This invention relates to suspension systems, objects, storage units and vehicles comprising same, as well as methods of use thereof.
It is known that if a vehicle is subjected to sudden external forces, such as those caused when the vehicle crashes into another object or when the vehicle is impacted by an explosion, damage to objects and injury to occupants within the vehicle will likely occur.
One type of seat known to be particularly safe when subjected to sudden external forces is a suspension seat held in a suspended position by a suspension apparatus above a floor of a vehicle. An advantage of such suspension seat may be that it distances a user seated thereon from an explosion below a vehicle. Suspension seats may comprise a seat portion and a back portion, similar to regular seats, and are normally secured to inner surfaces of the vehicle, particularly the lower and upper surfaces thereof via the suspension apparatus for holding the seat portion in a substantially horizontal orientation and the back portion in a substantially vertical orientation, thereby enabling a user to sit thereon similar to a normal seat.
A suspension apparatus may comprise elongated suspension elements for anchoring a suspension seat such that it is spaced from the floor or other inner surfaces of a vehicle it is disposed within. The elongated suspension elements of a suspension apparatus may all be non-rigid elements, meaning elements which do not transfer compression forces impacting the inner surface of the vehicle to which the elongated element is attached to the suspension seat, as would occur via rigid elements, thereby providing a high level of safety for a user of the suspension seat.
The suspension apparatus may also comprise an anchoring arrangement which includes static and/or dynamic connection elements, defined below, which engage the inner surfaces of the vehicle and suspension seat as well as engaging the elongated suspension elements of the suspension apparatus to allow it to be held in a predetermined spatial disposition. The anchoring arrangement may further comprise intermediate connection elements for connecting an elongated suspension element to a connection element on the inner surfaces of the vehicle or to the suspension seat. An example of an intermediate connection element is a carabiner.
Suspension seats having more than one operational state while suspended are known, for example from US Publication No. 2007/0170742 A1, which discloses a suspension seat having a seat portion which can be folded or pivoted between a sitting position and a storage position by raising the rear end of the seat portion.
DE 10130631 discloses a suspension seat fixed on a seat console, suspended by a support arm from the roof on the seat and/or on the seat console and/or on the support arm. The seat console is braced against the vehicle floor and/or the lower area of the side wall through connecting elements which can only transfer tensile forces and not compression forces.
The present invention relates to vehicles, suspension systems, suspension apparatus' and objects to be suspended, storage units, and methods of use thereof. The present invention comprises a plurality of features, each of which being inventive in itself. Each inventive feature may be used in combination with other inventive features described herein or used independently thereof.
For the purposes of the specification and the claims that the terms below are defined as follows:
According to one inventive feature, there is provided a vehicle comprising lower and upper surfaces, an object and a suspension apparatus for holding the object in a suspended position in the vehicle; the object having opposite rear and front edges, and adjacent first and second halves extending between the rear and front edges; the suspension apparatus being adapted to anchor the object to the lower surface of the vehicle via elongated suspension elements, and comprising first and second elongated suspension elements; each elongated suspension element comprising first and second ends and an intermediate portion therebetween; the first elongated suspension element being connected via the first end thereof to a first point on the object's first half, and being connected via the second end thereof to a first point on the vehicle's lower surface disposed closer to the objects second half than to the first half thereof; the second elongated suspension element being connected via the first end thereof to a second point on the object's second half, and being connected via the second end thereof to a second point on the vehicle's lower surface disposed closer to the object's first half than to the second half thereof.
The arrangement of the first and second elongated suspension elements described above may be referred to below as the ‘cross-over arrangement’.
One of the advantages of the vehicle above may be that, during an explosion underneath the vehicle more proximate a first side of the object than a second side, elevation and other motion on the first side of the object caused by the explosion are reduced, since the first side is anchored from a point on the lower surface of the vehicle less effected by the explosion. Additionally, since both sides of the object are anchored to the lower point in this manner they both may have this advantage.
The second ends of the first and second elongated suspension elements may be either directly or indirectly connected to the first and second on the lower surface.
In order to describe further constructional features, it should first be noted that the object may further comprise a lower portion and an upper portion. The first and second halves mentioned above may be halves of only the lower portion. The lower portion of the object may further comprise a bottom surface facing the lower surface of the vehicle. The first half of the lower portion may further comprise a first peripheral edge extending between the rear and front edges, and the second half of the lower portion further may comprise a second peripheral edge extending between the rear and front edges.
Regarding the distance between the points on the lower surface of the vehicle: the first and second points on the lower surface may be separated by a distance of at least 200 mm, or by a distance having a magnitude greater than a distance between points on the first and second peripheral edges closest to the second and first points on the lower surface, in a plan view of the object and lower surface of the vehicle.
One of the advantages of increasing the distance between the points on the floor may be that the elongated suspension elements provide better anchorage of the side of the object to which they are connected, reducing the elevation and twisting motion thereof during an explosion proximate the side of the seat to which they are connected.
Regarding the position of the points on the floor, in a plan view of the object and lower surface of the vehicle: the first point on the lower surface may be spaced from the second peripheral edge in a direction away from the first peripheral edge and/or the second point on the lower surface may be spaced from the first peripheral edge in a direction away from the second peripheral edge. In such cases, the points are distanced from the object, which may be advantageous as explained above. Additionally, when the first and second points on the floor are spaced from any of the edges of the object, such arrangement may facilitate convenient access for a person to secure the elongated suspension elements to the points. Such convenient access may also be facilitated when the first point and/or the second point on the lower surface of the vehicle is spaced from the front edge of the object in a direction away from the rear edge of the object. The first point on the lower surface of the vehicle may be spaced from the second peripheral edge in a direction away from the first peripheral edge, and spaced from the front edge of the object in a direction away from the rear edge thereof. The second point on the lower surface may be spaced from the first peripheral edge in a direction away from the second peripheral edge, and spaced from the front edge of the object in a direction away from the rear edge thereof. Both of the latter two arrangements may have the advantages described above.
It should be noted however that the lower points need not necessarily be spaced from the edges of the object to allow convenient access thereto, and that an advantageous installation position may also occur when: the first and second points on the lower surface of the vehicle are closer to the front edge of the object than the rear edge thereof; or the first and second points on the object are each disposed closer to the front edge of the object than the rear edge thereof; or the first and second points on the object are disposed at corners thereof, i.e. at the intersection of the front edge and peripheral edges of the object.
When[e1] the object is in the suspension position, and hence the first and second lower elongated suspension elements are taut: in the front view of the object, an angle less than 25 degrees may be formed between the first and/or second lower elongated suspension element with the bottom surface of the lower portion of the object; in the plan view of the suspension apparatus, an X-shaped arrangement may be formed by at least a portion of the first and second lower elongated suspension elements; such X-shaped arrangement may have an angle, in the range of about 0 to 45 degrees, or about 5 to 30 degrees, formed between the first and second lower elongated suspension elements and, in the plan view of the suspension apparatus.
The suspension apparatus may further comprise third and fourth elongated suspension elements. The third elongated suspension element may be connected at a first end thereof to a third point on the object's first half, and connected at the second end thereof to a third point on the lower surface of the vehicle. The fourth elongated suspension element may be connected at the first end thereof to a fourth point on the object's second half, and connected at the second end thereof to a fourth point on the lower surface of the vehicle. Both of the second ends of the third and fourth elongated suspension elements may be either directly or indirectly connected to the third and fourth points on the lower surface. The first and second points on the object may be closer to the front edge thereof than to the rear edge thereof and the third and fourth points on the object may be closer to the rear edge of the object than to the front edge thereof.
Regarding the position of the points on the lower surface of the vehicle: the first and third points may constitute a single spatial point and the second and fourth points may constitute a single spatial point; the first and fourth points may constitute a single spatial point and the second and third points may constitute a single spatial point; the first, second, third and fourth point may all be spaced from each other.
Regarding the arrangement of the elongated suspension elements: in a side view of the object, angles formed between the third and/or fourth elongated elements with the lower surface of the vehicle may be of smaller magnitude than angles formed between the first and/or second elongated elements with the lower surface of the vehicle.
The suspension apparatus may be free of an additional suspension element connected between the object and the lower surface of the vehicle, such connection being within a distance of 200 mm of the first or second points on the object. Similarly, in a case where the first and second halves of the object each have a longitudinal dimension extending between the rear and front edges and a transverse dimension perpendicular to the longitudinal dimension, the suspension apparatus may be free of an additional suspension element connected between the object and the lower surface of the vehicle, the connection of the additional suspension element to the object being within a distance equal to the transverse dimension of the first and second halves, to the first or second points on the object.
Some of the lower elongated suspension elements may be significantly more tensioned than others, which may provide a desired motion of the object during an explosion. For example, where there are elongated suspension elements connected to the object proximate to the rear edge thereof and two elongated suspension elements connected to the object proximate to the front edge thereof, the two elements connected proximate to the rear edge may be tensioned (for example using a tensioning mechanism) and the two elements connected proximate to the front edge may be loose (or relatively looser than the tensioned elongated elements).
In accordance with a first aspect of another inventive feature, there is provided a vehicle having lower and upper surfaces, and comprising an object and a suspension apparatus adapted to hold the object in a suspended position; the object having front and rear edges; the suspension apparatus comprising first, second, third and fourth elongated suspension elements, each having first and second ends, and an intermediate portion therebetween; the first ends of the first and second elongated suspension elements being connected to the object more proximate to the front edge of the thereof than to the rear edge, and connected via the second ends thereof to the lower surface of the vehicle; the first ends of the third and fourth elongated suspension elements being connected to the object more proximate to the rear edge thereof than to the front edge, and connected via the second ends thereof to the lower surface of the vehicle; the third and fourth elongated suspension elements being more tensioned than the first and second elongated suspension elements.
The elongated suspension elements may be arranged in the cross-over arrangement and any manner described hereinabove or below.
One of the advantages of such tensioning of the elongated suspension elements may be that during an explosion beneath the vehicle the rear elongated elements (the third and fourth elongated suspension elements) may become loosened from their tensioned state, projecting the object in the direction of the front edge thereof, causing the front elongated elements (the first and second elongated elements), to become tensioned and restrain movement of the object.
The object may be further connected to an upper surface of the vehicle via at least one elongated suspension element connected to the object at a portion thereof more proximate the rear edge than the front edge. In such case it will be appreciated that the relatively higher tensioning of the elongated suspension elements connected proximate to the rear edge of the object, compared with the suspension elements connected proximate to the front edge of the object, may be advantageous since a portion of the object proximate the front edge thereof is less stable during an explosion than a portion of the object proximate the rear edge thereof, since the rear edge is anchored to both the lower and upper surfaces of the vehicle. This may be of particular advantage when the first and second elongated suspension elements (i.e. the elements connected adjacent to the front edge of the object) are arranged in the cross-over arrangement.
In accordance with another aspect of the inventive feature, there is provided a method for suspending an object in a vehicle with elongated suspension elements, the object comprising lower and upper portions, the lower portion comprising a rear edge proximate the upper portion and a front edge distal therefrom, the vehicle having lower and upper surfaces; each of the elongated suspension elements comprising first and second ends and an intermediate portion extending therebetween, the method comprising:
In accordance with both aspects above, the elongated suspension elements connected to the object's lower portion proximate the front edge: may be connected by hand without the use of a tensioning mechanism; may be loose (or relatively looser than the elongated suspension elements connected to the object's lower portion proximate the rear edge).
According to another inventive feature, there is provide a vehicle having lower and upper surfaces, an object, and a suspension apparatus adapted for holding the object in a suspended position in the vehicle; the object having opposite rear and front edges, and adjacent first and second halves extending between the rear and front edges; the suspension apparatus comprising first and second lower elongated suspension elements adapted to anchor the object to the lower surface of the vehicle, and first and second connection elongated suspension elements; each of the elongated suspension elements comprising first and second ends and an intermediate portion therebetween; the first lower elongated suspension element being connected via a first end thereof to a first point on the object's first half, and being connected via the second end thereof to a first end of the first connection elongated suspension element; the second lower elongated suspension element being connected via the first end thereof to a second point on the object's second half, and being connected via the second end thereof to the first end of the second connection elongated suspension element; the second end of the first connection elongated suspension element being connected to a first point on the lower surface of the vehicle; the second end of the second connection elongated suspension element being connected to a second point on the lower surface of the vehicle; the first point on the vehicle's lower surface being disposed closer to the object's second half than to the first half thereof; the second point on the vehicle's lower surface being disposed closer to the object's first half than to the second half thereof.
Thus the second ends of first and second lower elongated suspension elements are indirectly connected to first and second points on the lower surface.
The second end of the first lower elongated suspension element may be connected to a first connection element disposed higher than and spaced from the first point on the lower surface of the vehicle and closer to the second half of the object than the first half thereof. The second end of the second lower elongated suspension element may be connected to a second connection element disposed higher than and spaced from a second point on the lower surface of the vehicle and closer to the first half of the object than the second half thereof;
Regarding the position of the points, when the object is in a suspended position and hence the elongated suspension elements are taut, in the plan view of the object and lower surface of the vehicle: the first point on the lower surface may be directly underneath the first connection element or spaced therefrom in a direction away from the object's first half; the second point on the lower surface may directly underneath the second connection element or spaced therefrom in a direction away from the object's second half. Such positioning may keep the elongated suspension elements taut.
The suspension apparatus may further comprise third and fourth lower elongated suspension elements. The third lower elongated suspension element may be connected at a first end thereof to a third point on the object's first half. The fourth lower elongated suspension element may be connected at the first end thereof to a fourth point on the object's second half. In the plan view of the object and lower surface of the vehicle the first and second points on the object may be closer to the front edge thereof than the rear edge and the third and fourth points on the object may be closer to the rear edge thereof than the front edge. The third lower elongated suspension element may be connected to the first connection element and the fourth lower elongated suspension element may be connected to the second connection element, or vice versa.
The vehicle may further comprise an elevated floor disposed above and spaced from at least a portion of the lower surface. In such case, the lower elongated suspension elements may be connected to the connection suspension elements at a height higher than the height of the floor.
Yet another inventive feature provides a suspension system for use in a vehicle having a lower surface; the suspension system comprising an object and a suspension apparatus for holding the object in a suspended position in the vehicle; the object comprising a lower portion and an upper portion, the lower portion of the object being biased for pivotal motion towards the upper portion; the suspension apparatus comprising at least one elongated suspension element adapted to anchor the lower portion of the object to the lower surface of the vehicle in the suspended position, and a fast release detachment mechanism connected to the at least one elongated suspension element; the fast release detachment mechanism being adapted to be brought from an attached state to a detached state; wherein when the object is held in a suspended position and the fast release detachment mechanism is in the attached state, the lower portion of the object is arrested from pivoting towards the upper portion thereof by connection of the elongated suspension element between the lower portion and the lower surface of the vehicle, and when the fast release detachment mechanism is brought to the detached state, the lower portion of the object is no longer connected to the lower surface of the vehicle via the elongated suspension element allowing pivotal motion of the object's lower portion.
Yet another inventive feature may provide a suspension seat adapted to be brought from a deployed state, which enables a person to sit thereon with their back resting against a back portion of the seat, to an undeployed state, in which at least a part of the back portion may be moved sufficiently so as to allow a person passage through a back-support region previously obstructed by the back portion in the deployed state.
According to one aspect of this inventive feature, there is provided a suspension system comprising a suspension seat and a suspension apparatus for use in a vehicle having lower and upper surfaces; the suspension seat including a seat portion and a back portion; the suspension apparatus being adapted to engage the lower and upper surfaces of the vehicle and to suspend therebetween the suspension seat with the seat portion in a substantially horizontal orientation; the back portion being adapted to be brought to a deployed state and an undeployed state, wherein in the deployed state the back portion is in a substantially vertical orientation occupying a back-support region of the suspension system above the seat portion, and in the undeployed state the back portion has at least a part thereof moved away from the back-support region to enable passage through the back-support region of the suspension apparatus.
In the deployed state the back portion may be attached to the suspension apparatus, and in the undeployed state the back portion may be detached from the suspension apparatus. The at least part of the back portion may be detachably attachable to the suspension apparatus. Such detachable attachment may be accomplished by the at least part of the back portion comprising at least one fastener element for connection to the suspension apparatus. In such case, the suspension apparatus may further comprise a fastener element adapted to engage the at least one fastener element of the back portion, wherein the fastener element of the suspension apparatus is disposed closer to the upper surface than the lower surface of the vehicle, when the suspension seat is suspended in the vehicle. While only a part of the back portion may be detached, it should be understood that the entire back portion may be adapted to be detached from the suspension apparatus to enable passage through the back-support region of the suspension apparatus, in which case the entire back portion may be detached from the suspension apparatus in the undeployed state.
The seat portion may be adapted to remain in a substantially horizontal orientation when the back portion is in the undeployed state. The seat portion may have opposite rear and front edges, adjacent first and second halves extending between the rear and front edges, and a bottom surface. The rear edge being closer to the back portion than the front edge. It will be appreciated, that seat portions may not necessarily be square or rectangular shaped.
The back portion and the seat portion each may be integrally and pivotally joined along a merging line. Alternatively, the back portion and seat portion may, for example, be two separate portions or completely detachably attachable portions.
The suspension apparatus may include two spaced apart and substantially vertical elongated suspension elements attached to the back portion, when the back portion is in the deployed state. In such case the back-support region may be constituted by an area above the seat portion and between portions of the vertical elongated suspension elements. The suspension apparatus may further include a substantially horizontal stabilizing element attached to both of the vertical elongated suspension elements and disposed above the back-support region, for providing structural support to the suspension apparatus. The suspension apparatus may comprise at least one elongated suspension element. It will be appreciated that the suspension apparatus may be free of rigid elongated suspension elements adapted for connection to the lower or upper surfaces of the vehicle.
The back-support region may have a horizontal dimension of at least 50 centimeters. The back-support region, disposed above the seat portion, may have a vertical dimension of at least 80 centimeters. Such dimensions may allow the back-support region to be of sufficient size to allow passage therethrough.
According to another aspect of the inventive feature, there is further provided a vehicle having a passageway and lower surface and upper surfaces, the vehicle comprising a suspension seat and a suspension apparatus adapted for holding the suspension seat in a suspended position in the vehicle; the suspension seat including a seat portion and a back portion; the suspension apparatus comprising at least one suspension element and comprising plurality of connection elements engaging the suspension seat and points on the lower and upper surfaces of the vehicle disposed above and below a portion of the passageway; the suspension apparatus being adapted to suspend the suspension seat in the suspended position in said portion of the passageway, with the seat portion in a substantially horizontal orientation and the back portion in a substantially vertical orientation, via connection of the at least one suspension element with the connection elements; the back portion of the suspension seat being adapted to be brought to a deployed state and an undeployed state; wherein in the deployed state the back portion is attached to the suspension apparatus above the seat portion in the substantially vertical orientation and passage is prevented through the portion of the passageway via a back support region of the suspension apparatus, and in the undeployed state at least a part of the back portion is detached from the suspension apparatus enabling passage through the portion of the passageway via the back support region of the suspension apparatus.
The vehicle may comprise first and second areas separated by an internal partition wall, the partition wall being formed with an opening allowing passage between the first and second areas. In such case the opening constitutes the portion of the passageway mentioned above. The vehicle may comprise an outer wall, the outer wall being formed with an exit allowing passage into and out of the vehicle. In such case the exit may constitute the portion of the passageway mentioned above.
In accordance with a further aspect of this inventive feature, there is provided a vehicle having a passageway and suspension system, the suspension system comprising a suspension seat at least partially blocking a portion of the passageway when in a first state and enabling passage through the portion of the passageway when in a second state.
Suspension of More than One Object
In accordance with a first aspect of the inventive feature, there is provided a suspension system for use in a vehicle; the suspension system comprising a first object and a suspension apparatus for holding the first object in a suspended position in a vehicle; the suspension apparatus comprising at least one elongated suspension element adapted to hold the first object in the suspended position; the suspension apparatus and/or the first object being adapted to at least partially suspend an additional object, the additional object being disposed at a height above the first object or at its side when the first object is seen in the front view.
The first object may further comprise a detachably attachable engagement member secured thereto adapted for attachment of the additional object. The engagement member may be a rigid elongated object, such as a rod, or the engagement member may be a clamp-like member adapted to at least partially lockingly receive therein a rigid elongated member, such as a rod.
The object may further comprise a handle adapted to release the additional object from an attached state.
The object may be a suspension seat comprising a seat portion and a back portion, and the engagement member may be mounted on the seat portion.
The suspension system may further comprise a storage unit adapted for detachable attachment to the engagement member. The storage unit may be adapted to hold ammunition. Notably, it may be advantageous to store ammunition in a suspended position, and thereby distance it from an area which may be directly impacted by an explosion.
The additional object may be a storage unit.
In accordance with another aspect of the inventive feature, there is provided a suspension system for use in a vehicle having upper and lower surfaces; the suspension system comprising an object, a suspension apparatus for holding the object in a suspended position in the vehicle, and a storage unit; the object having a lower portion and an upper portion; the suspension apparatus comprising at least one upper elongated suspension element adapted to anchor the upper portion of the object to the upper surface of the vehicle in the suspended position; the storage unit being connected to the at least one upper elongated suspension element.
The storage unit may be adapted to be mounted at a height higher than the upper portion of the object (i.e. above the object, in a front or side view of the object).
The object may have a first substantially vertical portion and a second substantially horizontal portion extending from the first portion. In such case the storage unit may be positioned such that at least a majority thereof is not disposed above the second portion, in a plan view of the object, or the entire storage unit may be not disposed above the second portion.
When a person is to sit on the object, such as when the object is a seat and the first portion constitutes a back portion and the second portion constitutes a seat portion, such positioning of the storage unit, not above the seat portion and hence a head of a user sitting thereon, may have a safety advantage.
The storage unit may be made of non-rigid material, for example a flexible net. When there is a plurality of upper elongated suspension elements, the net may be adapted to extend between them to define a storage area therebetween. The storage unit may be made of fabric material. The storage unit may be free of any rigid elements.
The additional object may be held in a suspended position by two or more suspended objects
According to yet another aspect of the inventive feature, there is provided a suspension system for use in a vehicle comprising lower and upper surfaces, the suspension system comprising first and second objects, a suspension apparatus, and a platform; each of the first and second objects being adapted to be held by the suspension apparatus in a suspended position; the suspension system being adapted to at least partially suspend the platform via the first and second objects.
The suspension apparatus may comprise one or more elongated suspension elements and the first and second objects may be suspended by different such suspension elements or by different portions of one such suspension element.
The platform may be free of elongated suspension elements directly connected to the upper or lower surfaces of the vehicle.
The platform may be suspended solely by the first and second objects.
Thus the suspension system may save space by not requiring room in a vehicle for additional elongated suspension elements adapted to suspend a platform. Additionally, installation and removal of items mounted on the platform may be faster than installation and removal of items connected to the vehicle via a suspension apparatus.
When each of the first and second objects further have aligned bottom surfaces, the platform may be constituted by a bridge section extending between the first object and the second object aligned with the bottom surfaces of the lower portions.
An item may be mounted on the platform in a pivotal manner. Such item may be a seat, frame, stretcher, storage unit, etc. In a case where the item may be adapted to pivot, access to storage areas or access points of a vehicle may become accessible. Such feature may be advantageous in vehicles which are lacking in space. Notably, suspension seats and suspended objects normally are connected to the roof via suspension elements and are not adapted for pivotal motion to provide access therebehind.
The platform may be constituted by an elevated floor spaced from the lower surface of the vehicle and extending between the first and second objects. The elevated floor may be spaced at least 250 mm lower than the bottom surface of the first and/or second object, and preferably at least 300 mm. The elevated floor may be adapted to suspend an item thereon.
Such elevated floor may be advantageous in that it may provide protection against an explosion under the lower surface of a vehicle, while allowing a user to feel more comfort than when they are forced to put their feet in a restricted position, such as elevated on a foot rest.
According to a further aspect there is provided a vehicle having lower and upper surfaces and comprising a suspension system having any of the features of the previous aspect. In such case, the distance from a portion of the upper surface of the vehicle to a lower portion of an object directly therebelow, in the plan view, may be at least 1000 mm or greater. This may be to ensure that a person seated on the object (or a seat mounted thereon) is sufficiently spaced from the upper surface of the vehicle.
The elevated floor may be spaced from the lower surface of the vehicle a distance of between about 50 mm to 150 mm, and preferably about 100 mm, to ensure ample spacing from an explosive impact to the lower surface.
Other dimensions of the elevated floor may include: when the object's front edge has a length, the elevated floor may have a width having a magnitude of length greater than the length of the front edge; a dimension perpendicular to the width of the elevated floor may be of a magnitude of length greater than 250 mm.
The elevated floor may further comprise a planar surface, a plurality of connected rigid support members parallel with the planar surface and upon which the surface is mounted, and a plurality of rigid connection members oriented transverse to the rigid support members; each of the rigid connection members comprising a lower end, an upper end, and an intermediate portion extending therebetween, the lower end being connected to one of the rigid support members, and the upper end connected to one of the objects.
Similar to above, each object may further comprise a detachably attachable engagement member. Where there is more than one object with such members, the engagement members may be disposed a distance of about 300 mm-800 mm from each other. There may be provided a stretcher having two or more attachment members adapted to engage such engagement members, thus the stretcher may be suspended at one end thereof via two such objects having detachably attachable engagement members and at the second end thereof via another suspension apparatus. The stretcher may be suspended between four objects. Thus an injured person may be transported in a suspended position, while in a horizontal position, between suspended objects (e.g. in a passageway), without decreasing seating space in a vehicle or exposing the person to danger of an explosion by being placed on the floor.
It will be understood that in accordance with all aspects above the one or more objects may be seats.
Yet a further aspect of the inventive feature including suspending an additional object via a first object is via the use of a holder or frame.
According to another aspect of the inventive feature, there is provided a suspension system adapted for at least partially suspending an object in a suspended position in a vehicle via at least one elongated suspension element, the suspension system comprising a suspended holder adapted for connection to at least one elongated suspension element and to be suspended thereby, the holder being further adapted for having an object detachably attached thereto and for holding the object in a suspended position.
The holder may be a single component. The holder may be made of two or more sub-components joined together The holder may comprise at least one mounting element for mounting an object to the holder thereby. The mounting element may be adapted for fast-connection and/or fast release. In such case the mounting element, for example, may comprise one or more projections and the object may be adapted to be mounted on the projections. The at least one mounting element may comprise at least one locking element for ensuring that an object mounted on the holder is secured to the holder. In such case, the locking element may be adapted for fast-connection and/or fast release. In such case the mounting element may be formed with a bore and the locking element may be a pin adapted for insertion into the bore.
The holder may be of substantially planar shape. The holder may have a transverse dimension far greater than the thickness thereof. The holder may have a width of 20 cm or less. The holder may have a linear section and a non-linear section extending from one end of the linear section. In such case the linear section and non-linear section may be shaped so as to have a seat-like shape and thereby be adapted to have a seat mounted thereon.
The holder may be made of a sheet of a rigid material.
The holder may comprise lower and upper portions and an intermediate portion therebetween. Each of the lower and upper portions may comprise connection elements and thus be adapted for connection to the at least one elongated suspension element thereby. The connection elements may be static connection elements.
The suspension system may further comprise the at least one elongated suspension element, via which the holder is to be suspended. The at least one elongated suspension element may be a plurality of elongated suspension elements. The at least one elongated suspension element may be any number of elongation suspension elements arranged to suspend the holder in any arrangement disclosed hereinabove or below.
The suspension system may further comprise the object to be suspended. The object may be free of connection elements adapted for connection to at least one elongated suspension element. In such case the object may be held in a suspended position completely via the holder. Alternatively, the object may be adapted for connection to at least one elongated suspension element, for partial suspension thereby. In such case the holder may only partially suspend the object. The object may be adapted to be mounted on the holder in a static manner. Such adaption may include the object comprising a strap for securing to the holder, or a mounting projection, or a recess adapted to receive a mounting projection, etc. The object may be a computer, a display, a gunner step, a stretcher, a seat, etc.
When the object is a seat: the seat may be a standard suspension seat, or may be adapted for suspension; the seat may comprise a seat portion and back portion integrally formed with each other; the seat may comprise a seat portion and back portion which are not integrally formed, in such case the back portion and/or holder may be adapted to allow the back portion to be mounted at different positions on the holder, and the seat portion and/or holder may be adapted for connection to each other; the seat portion and back portion may be attached to each other via a flexible and/or elastic strip connection member. The seat portion may comprise connection elements, adapted for connection to at least one elongated suspension element. The seat portion in any of the seats above may be adapted for connection to elongated suspension elements. The back portion and seat portion may comprise connection elements adapted for connection to at least one elongated suspension element.
It will be understood that any of the objects above may comprise elements adapted to mount or lock the object to the holder. Alternatively the mounting and/or locking elements may be comprised by the holder only, or both the object and holder may be adapted for connection to each other.
The suspension system may be configured to allow the holder to be positioned at different heights. This may be accomplished, for example, by shortening or lengthening the at least one elongated suspension element.
It would be understood that an object may be secured to the holder in any suitable manner, and that the holder may be formed with elements adapted to allow securing of objects thereto.
One advantage of using a holder as described above, may be that objects can be quickly suspended thereon and removed therefrom, since the object itself does not need to be connected to a vehicle, at least fully, by elongated suspension elements in a highly tensioned state.
Another advantage may be the reduced amount that an object for suspension needs to be modified for suspension. For example if the object is a conventional suspension seat, such seat may need to have industrial strength static connection elements welded to several portions thereof, each portion of such seat needing to be constructed to withstand the high forces exerted thereon by elongated suspension element in a highly tensioned state. Where a holder of the above-described type is used, the object may require substantially less modification, as it need only be adapted to be mounted on a holder. Or such seat may only require less connection elements than a conventional suspended object. The reduced need for modification of such seat for elongated suspension elements may allow a lighter and/or smaller seat to be used.
The holder may be shaped such that it functions as a part of a back portion of a seat. In such case the seat portion and back portion may be non-integral with each other. The back portion may have a reduced thickness, since at least a portion of the normal function thereof may be provided by the holder. Such seat may also have a compact folding position due to the reduced thickness of the back portion and/or reduction of material used to connect the back portion and seat portion.
According to another inventive feature, there is provided a vehicle comprising an upper surface, an object and a suspension apparatus for holding the object in a suspended position in the vehicle; the object having a first imaginary vertical reference plane symmetrically dividing it into two halves and a second imaginary vertical reference plane perpendicular to the first plane; the suspension apparatus comprising two pairs of elongated suspension elements each comprising first end and second ends and an intermediate portion extending therebetween, and being adapted to anchor the object to the upper surface of the vehicle; the first ends of each pair of elongated suspension elements engaging an object connection point disposed on the object, the object connection points of the two pairs being disposed at different sides of the first plane; each pair having a second end of one of the elongated suspension elements engaging a first vehicle connection point disposed on the upper surface of the vehicle, and a second end of the other elongated suspension element engaging a second vehicle connection point disposed on the upper surface of the vehicle, the first and second vehicle connection points being disposed at different sides of the second plane; the first vehicle connection points of the two pairs being disposed closer to each other than the second vehicle connection points of the two pairs.
One of the advantages of the above arrangement may be that during an explosion underneath the vehicle the object is significantly prevented from undesired twisting.
The first vehicle connection points may be separated by a distance of between 100-200 mm. Such distance may be advantageous in that it is not so small as to cause the first vehicle connection points to behave during an explosion as a single pivot point.
The second vehicle connection points may be, in the plan view of the object and upper surface of the vehicle, spaced further from each other than the spacing of the outer peripheral edges of the object disposed along a third imaginary vertical reference plane parallel with the second imaginary vertical reference plane. In such view, both of the second vehicle connection points may be spaced from the object such that they are not disposed thereabove. Such of the second vehicle connection points may be advantageous in that it does not leave elements above a head of a person sitting in the object, which may be impacted during an explosion under the vehicle.
In a side view of the object, each of the first, second, third and fourth upper elongated suspension elements may forms an angle of at least 10 degrees from a vertical axis passing through the respective point on the upper portion to which the elongated suspension element is connected.
Such angle may provide additional stability to the suspension system.
The object connection points may be disposed at corners of the object.
In accordance with a first aspect of another inventive feature, there is provided a vehicle comprising inner surfaces, an object, and a suspension apparatus for holding the object in a suspended position in the vehicle; the suspension apparatus comprising a dynamic connection element mounted on one of said inner surfaces of the vehicle, a first static connection element mounted on one of said inner surfaces of the vehicle, a second static connection element mounted on the object, and an elongated suspension element adapted to hold the object in the suspended position; the elongated suspension element comprising first and second ends and an intermediate portion extending therebetween; the elongated suspension element engaging the dynamic connection element via the intermediate portion thereof, and engaging the first and second static connection elements via the first and second ends thereof.
The use of a dynamic connection element may be advantageous in situations where the object is suspended close to a side surface or upper surface of a vehicle. If a vehicle uses a suspension apparatus with a short upper elongation element, when an explosion occurs under the vehicle there may be a violently acceleration upwards of the upper and side surfaces of the vehicle, together with the short elongated suspension element connected to an object. Consequently the short elongated suspension behaves in a manner similar to a rigid element and violently jerks the object upwards transferring all of the force of the explosion to the object. It has been found that a longer elongated member stretches more during an explosion (high forces of an explosion even causing stretching of high strength elongated elements). Additionally it has been found that by creating a non-linear path of the upper elongated element, shock waves may be somewhat dissipated by diversion of their path. Thus, use of a dynamic connection element having a minimum predetermined length to allow stretching thereof during sudden tensioning thereof by an explosion, allows a longer elongated element to be used, even when an object to which the elongated object is attached is disposed in close proximity to a wall, and an optimal angle for static connection of the elongated element to the side wall for a desired suspension position would have necessitated a shorter elongated element. Elongated suspension elements of greater than 80 mm have been found to stretch in a suitable manner.
The elongated suspension element may be greater than 80 mm.
Using the dynamic connection element, the optimal angle may be achieved while utilizing a long elongated element along a non-linear path.
The first and second static connection elements and the dynamic connection elements may be disposed in a non-linear path.
The dynamic connection element may be secured to a side surface of a vehicle. The dynamic connection element may be proximate to the upper surface.
In accordance with another aspect of the inventive feature, there is provided a vehicle comprising inner surfaces, an object and a suspension apparatus; the suspension apparatus comprising at least one elongated suspension element adapted to hold the object in the suspended position, a tensioning strap, a tensioning mechanism engaging the tensioning strap, and a dynamic connection element mounted on one of said inner surfaces of the vehicle; the tensioning strap comprising first and second ends and an intermediate portion extending therebetween; the tensioning mechanism being mounted on the object or on one of the inner surfaces; the intermediate portion of the tensioning strap engaging the dynamic connection element in a manner that allows the intermediate portion to move relative to the dynamic connection element, when the tensioning mechanism is operated.
The suspension apparatus may comprise a single tensioning strap or a single tensioning mechanism.
The tensioning strap may have one free end, i.e. an end which is not connected to the object or vehicle.
The inner surface upon which the dynamic connection element may be mounted may be a floor of the vehicle. The tensioning mechanism may be mounted on a side surface of the vehicle.
Some of the advantages of using a dynamic connection element may be that:
The dynamic connection element may be mounted on the same inner surface of the vehicle as the tensioning mechanism. In such case the intermediate portion of the tensioning strap may engage the dynamic connection element in a manner that allows the intermediate portion thereof to move relative to the dynamic connection element when the tensioning strap is not taut, and a portion of the tensioning strap which extends between the tensioning mechanism and the dynamic connection element may be substantially parallel with the inner surface upon which both are mounted, when the tensioning strap is taut, allowing easy release of the tensioning strap when the tensioning mechanism is operated.
The suspension system may be free of dynamic connection elements on the object. The suspension system may be free of one or more dynamic connection elements on the upper surface of the vehicle. The suspension system may be free of elongated suspension elements which engage a dynamic connection element.
Suspension System with a Single Tensioning Strap and a Single Tensioning Mechanism
Still a further inventive feature, provides for a vehicle comprising inner surfaces, an object and a suspension apparatus for holding the object in a suspended position in the vehicle; the suspension apparatus comprising a single tensioning strap, a single tensioning mechanism engaging the tensioning strap, and at least one elongated suspension element adapted to hold the object in the suspended position; the tensioning strap having a first end, a second end and a intermediate portion extending therebetween; one of the first end of the tensioning strap and tensioning mechanism being secured to the object and the other one being secured to one of the inner surfaces of the vehicle; and when the tensioning mechanism is operated, thereby causing the tensioning strap to become taut, the object is moved in a desired direction causing the at least one elongated suspension element to become taut and suspend the object in the suspended position.
It will be appreciated, that since the at least one elongated suspension element is adapted to hold the object in the suspended position, the tensioning strap may be less strong than the at least one elongated suspension element as it is not designed to bear the load of the object and a user that may be seated thereon.
The suspension apparatus may be free of an additional tensioning mechanism.
A spatial arrangement of the suspension apparatus may be that, when the object in the suspended position and the tensioning strap is taut, the tensioning strap is slanted in a direction transverse the slanting direction of portions of the at least one elongated suspension element connected between the object and lower surface of the vehicle. The tensioning strap may be slanted in a direction similar to the slanting direction of portions of the at least one elongated suspension element connected between the object and upper surface of the vehicle.
The object may further comprise upper portion and lower portions, and being symmetrically divided into two halves by an imaginary vertical reference plane. The rear edge being more proximate than the front edge to the upper portion. In such case the tensioning mechanism may be mounted on the object on the upper portion and/or the lower portion, at a point of intersection of the first and second halves thereof. The tensioning mechanism may be mounted on: the upper portion at a point thereon within the lowest third of the upper portion, in a rear view of the object; a bottom surface of the lower portion.
A further inventive feature provides a suspension system comprising a suspension seat and a suspension apparatus adapted to hold the seat in a suspended position; the suspension seat comprising a back portion, a rigid seat portion, and a rigid support member; the suspension apparatus comprising at least one elongated suspension element; the rigid support member having first and second ends and an intermediate portion extending therebetween; the first end of the rigid support member and the rigid seat portion are adapted for static connection with each other at a seat point spaced from the at least one elongated suspension element; the second end of the rigid support member and the at least one elongated suspension element are adapted for static connection with each other at an element point spaced from the seat portion.
An advantage of the suspension system above may be that it allows use of a rigid structural member, without the disadvantage of compressive forces being transferred from a surface of a vehicle, during an explosion. Such disadvantage may not occur, since the rigid structural member itself may be suspended via the suspension apparatus and may be distanced from surfaces of the vehicle.
The suspension seat and suspension apparatus may be free of supporting means extending from the rigid seat portion at a point thereon spaced from the elongated suspension element to a point on either a back portion of the suspension seat or the suspension apparatus at a point disposed higher than the seat portion.
The rigid seat portion may comprise first and second peripheral edges extending between rear and front edges thereof. A maximum magnitude of length between proximate points on the first and second peripheral edges may be less than 450 mm. The maximum magnitude of length may be between 400 mm to 430 mm.
Some of the advantages of such suspension system may be that: the absence of side straps may ease use of the seat, as equipment worn will not become entangled with such straps; since no side straps extending from a portion of the at least one elongated suspension element above the rigid seat portion are needed to support the seat portion, a seat having a small width may be provided, than was previously needed for users wearing equipment on their belts, allowing more space in the vehicle.
The intermediate portion of the rigid support member may be of a length adapted to support the seat point in a substantially horizontal orientation.
The first end of the rigid support member may be adapted for detachably attachable engagement with the rigid seat portion.
The second end of the rigid support member may be adapted for detachably attachable engagement with the elongated suspension element.
The suspension seat may further comprise a back portion. The back portion may be made of a textile material. The suspension seat may further comprise a biasing mechanism adapted to pivot the seat portion upwardly about a merging area of the seat portion and back portion, when the rigid support member is detached from the seat portion and elongated suspension element. The back portion may be transparent.
The element point may be spaced at least 20 mm from an end of the elongated suspension element or, where a vehicle comprising such suspension system is provided with the suspension system, 20 mm from any rigid element directly connected to the lower surface of the vehicle or the lower surface of the vehicle. The spacing for either case may also be a distance of at least 80 mm.
The at least one elongated suspension element may be formed with a plurality of recesses adapted for engagement with the second end of the rigid support member. The at least one elongated suspension element may further comprise at least three adjacent bulging portions made of textile material, and a plurality of recesses formed between the bulging portions; the recesses being adapted for the engagement with the second end of the rigid support member.
The rigid seat portion may further comprise top and bottom surfaces, the bottom surface being formed with a plurality of recesses adapted for the engagement with the first end of the rigid support member.
It will be understood that each so-called ‘object’ mentioned above may be suspended in an advantageous way. Thus the object may be constituted by alternative items, depending on the need therefor in a vehicle:
One of the advantages of using a holder or a platform, is that they may be adapted to hold different elements. For example, off-the-shelf seats manufactured for applications other than suspension may be mounted on such holder or platform. Thus light, cheap seats, not comprising metal brackets and industrial strength parts for holding the brackets may be used. Additionally, the holder or platform allows a user to choose the most efficient use for space in a vehicle, by selecting such to support a seat or to be used as storage space.
General
In accordance with any of the inventive features above:
It will be understood that even though the claims of the present application do not include all inventive features above, such inventive features are not disclaimed and the applicant reserves the right to file divisional and/or continuation applications therefor.
In order to understand the invention and to see how it may be carried out in practice, embodiments will now be described, by way of non-limiting example only, with reference to the accompanying drawings, in which:
Examples of vehicles, suspension systems, suspension apparatus' and objects to be suspended, storage units, and as methods of use thereof, will now be described.

It should be noted that drawings of the present application are schematic and therefore may not show connection or intermediate connection elements, however any such omission does not deny the presence of such elements.
Referring now to the drawings wherein like reference characters designate like or corresponding parts throughout several views, there is shown in
The vehicle 10 comprises a lower surface 14 (
The suspension apparatus comprises an anchoring arrangement having a plurality of brackets 26 (
The vehicle 10 further comprises a first area 28 constituted by a drivers cabin and a second area 30 constituted by a passengers cabin.

The suspension apparatus 50 comprises two spaced apart and substantially vertical elongated suspension elements 58, a horizontal stabilizing element 60 attached to both of the vertical elongated suspension elements 58 at portions thereof adjacent to the upper surface 16 of the vehicle 10, upper side-support straps 62, a tensioning element 66, constituted by a ratchet, mounted on each of the vertical elongated suspension elements 58, and a plurality of intermediate connection elements 68.
The intermediate connection elements 68 include automatic carabiners 68A (sold under the trade name “Camp 782”), flight hooks 68B (sold under the trade name “CS-1125”), and D-shaped screw gate carabiners 68C (sold under the trade name “N-432”). It should be noted that each of the vertical elongated suspension elements 58 loops through carabiners 68A and thus has one linear vertical portion 58A (best seen in
The suspension apparatus 50 comprises a first front elongated suspension element 64A (
The vertical elongated suspension elements 58 comprises fastener elements 70 in the form of buckle receivers for snapping engagement with the fastener element 56 of the back portion 46. The buckle receivers 70 are disposed more proximate to the upper surface 16 than the lower surface of the vehicle 14, when the suspension seat is suspended in the vehicle.
In this example the elongated suspension elements (58, 64) are all in the form of high strength elongated suspension elements, which are bendable, and have a minimum tear strength of about 5000 kg, and low elasticity properties.

It should however be noted that if the suspension seat 12, did not comprise the horizontal stabilizing element 60, the back-support region 72 would be constituted by the area between the vertical elongated suspension elements 58, extending from the seat portion 44 until the upper surface 16. It should also be noted that the back-support region need not necessarily be rectangular. However, the back-support region should be a sufficiently large enough area to enable a person to traverse therethrough.
In operation, the suspension seat 12 is suspended in the portion 43 of the passageway 42 with the back portion 46 in a deployed state (as seen in

The suspension seat 254 comprises a seat portion 258 and a back portion 260. The seat portion 258 comprises opposite rear and front edges (262, 264), with the rear edge 262 being the closer edge to the back portion 260. The seat portion 258 further comprises adjacent first and second halves (266, 268) extending between the rear and front edges (262, 264), first and second peripheral edges (263, 265) extending between the rear and front edges, and bottom and top surfaces (267, 269, see
The suspension apparatus 256 is adapted to anchor the back portion 260 to the upper surface 252 of the vehicle, and comprises first and second lower elongated suspension elements (270A, 270B) adapted to anchor the seat portion 258 to the lower surface 250 of the vehicle. The first lower elongated suspension element 270A comprises a first end 272A connected to a first point 274A on the bottom surface 267 (as seen in
Notably,
It should be mentioned that when it is stated that one of the halves of the seat portion is ‘closer’ than the other half to a point on the floor, such should be understood to mean that the closer half of the seat portion is the one which has a point thereon which is spaced from the point on the floor a smaller distance than every point on the other half of the seat portion. To elaborate, in the present example the closest point on the first half 266 to first point 278A on the lower surface 250, is the point designated as 280 which is disposed at the intersection of the bottom surface 267 of the seat portion, the vertical plane X and the first half 266, and is spaced from the vertical plane Y the same magnitude of distance as point 278A. Therefore there are many points on the second half 268 which are closer to the point 278A than point 280, and therefore the second half 268 is closer to the point 278A than the first half 266. It will also be appreciated that any point on the lower surface, such point being disposed on an opposite side of the vertical plane X to the first half 266, will be closer to the second half 268 of the seat portion 258 than the first half 266 thereof.
Regarding positioning of various points, as can be understood visually, the imaginary vertical plane Y is interposed between the first and second points (278A, 278B) and the rear edge 262, but the vertical plane Y is not interposed between the first and second points (278A, 278B) and the front edge 262, thus in the present example:

Additionally, each of the first and second elongated suspension elements (270A, 270B) comprise a fast release detachment mechanism (314A, 314B), allowing the front edge 264 of the seat portion to be quickly released and, if needed, pivoted, when the fast release detachment mechanism is in a detached state.
Such indirect connection may be useful when used with a floating floor having apertures formed therein. An example of such floating floor is shown in

The seats (1114,1118A,1118B) are mounted on the base 1116. Notably seat 1114 is mounted on the central section 1180 of the base 1116, and is not connected to any of the elongated suspension elements 1196. Thus the seat 1114 is fully suspended by the central section 1180 which in turn is held in a suspended position by the seats (1118A,1118B) which themselves are connected to elongated suspension elements 1196 that are anchored to the upper surface 1106 of the vehicle 1100. The central section 1180 is also held by the first and second sections (1172,1178) of the base 1116, these sections (1172,1178) being anchored to the lower surface 1104 of the vehicle via elongated suspension elements 1196.
The base 1116 further comprises a frame 1190 extending upwardly from the upper face 1182. The frame 1190 includes side-frame elements (1190A,1190B) and a rear frame-element 1190C. The frame 1190 is formed with a recess 1192 bounded by the side-frame elements (1190A,1190B) and the rear frame-element 1190C.

Those skilled in the art to which this invention pertains will readily appreciate that numerous changes, variations and modifications can be made without departing from the scope of the invention mutatis mutandis. For example, any sufficiently strong connection elements may be used. Additionally, a part of the back portion engaging the suspension apparatus may be moved in any number of ways to allow passage through the back-support region, e.g. via a zip extending through the center of the back portion, by the entire back portion being detachable from the suspension seat, for example by fasteners being on each corner thereof, etc. The suspension seat may be placed at any position in a vehicle, for example at an exit thereof. The horizontal stabilizing element is an optional part of a suspension apparatus, and is added for providing a user more stability, and hence a more comfortable journey, during movement of the vehicle. Whilst an armored personnel carrier was exemplified, other vehicles such as planes and helicopters may also be examples of vehicles in accordance with the present invention. The suspension apparatus may be of any suitable configuration which can suspend a seat portion and a back portion and which may have a back-support region of sufficient size to allow passage therethrough. It should also be mentioned, that connection points between elongated suspension elements are not shown in all drawings but may be integral or attachable to the vehicle and suspension seat in accordance with the invention. Such connection elements may be attached to the suspension seat via a solid plate integral with or attached to the suspension seat and/or the seat portion or back portion may be formed with eyelets, etc.
