In addition, US 2015/0 034 641 A1, for example, discloses a life vest bag for an aircraft seat having a drawstring by means of which a life vest is able to be removed, when necessary, from the life vest bag by a passenger.
The object of the invention consists, in particular, in providing a generic life vest bag with advantageous properties with regard to a design. The object is achieved according to the invention by the features of claim 1, whilst advantageous designs and further developments of the invention are able to be taken from the subclaims.
The invention relates to a life vest bag, in particular to a passenger seat life vest bag, for example an aircraft seat life vest bag, having at least one receiving unit which comprises at least one receiving space for at least one life vest and at least one access opening to the receiving space, and having at least one closure unit which closes the access opening in at least one correctly closed state.
A life vest bag is to be understood, in particular, as a container for storing at least, preferably precisely, one life vest, in particular for a passenger and/or a driver of a vehicle, for example of a ship or a boat or a motor vehicle, in particular of a bus, or of a rail vehicle or an aircraft. In particular, the life vest is an inflatable life vest, for example with at least one gas pressure cartridge which is configured for inflating at least one float. In particular, the life vest is arranged in a stowed state at least in part, preferably entirely, in the receiving space. The life vest is advantageously folded and/or compressed and/or packed in the stowed state. The term “configured” is to be understood, in particular, as especially designed and/or equipped. An object being configured for a certain function is to be understood, in particular, as the object meeting and/or carrying out said certain function in at least one application and/or operating state.
The closure unit and the receiving unit are advantageously connected to one another so as to be captive, for example in an articulated manner. As an alternative to this or in addition to it, it is conceivable for the closure unit and the receiving unit to be connected to one another by means of at least one connection element. In particular, the connection element can be realized as a cord and/or a line and/or a tape.
In an open state, the life vest can preferably be removed from the receiving space, in particular through the access opening, without any damage. The life vest, at least in the stowed state, and the access opening preferably comprise an at least substantially identical cross section. A first object and a second object comprising an “at least substantially identical cross section” is to be understood, in this case, in particular, as a minimum surface area of a differential surface, which is formed when the cross sections are placed one on top of the other, being a maximum of 20%, advantageously a maximum of 10% and particularly advantageously a maximum of 5% of the surface area of the larger of the two cross sections for at least one cross section of the first object and at least one arbitrary cross section of the second object. It is also possible, however, for a cross section of the life vest and a cross section of the access opening to differ.
In the correctly closed state, the access opening and/or a region of the access opening which is uncovered and/or unclosed, in particular by the seal, advantageously comprises a cross section which is smaller than a cross section of the life vest in the stowed state, in particular parallel to the access opening. In particular, the life vest is arranged in the receiving space so as to be inaccessible in the correctly closed state. A cross section of an object, which, in the correctly closed state, is insertable into the receiving space in a damage-free manner and/or without damaging the closure unit and the receiving unit as well as, in particular, the seal, is advantageously a maximum of 2 cm2 or a maximum of 1 cm2 or a maximum of 0.5 cm2 and in a preferred manner a maximum of 9 mm by 9 mm. A length of an object, which, in the correctly closed state, is insertable into the receiving space in a damage-free manner and/or without damaging the closure unit and the receiving unit, is preferably a maximum of 99 mm, in a particularly preferred manner a maximum of 50 mm. It is conceivable for the access opening, in the correctly closed state, to comprise the same cross section as in the open state. It is conceivable, in particular, for the closure unit to cover and/or to span and/or to overlap the access opening in the correctly closed state at least in part, advantageously entirely.
An advantageous construction method can be provided, in particular, by the design according to the invention.
In addition, advantageous properties with regard to a low weight and/or to rapid and/or cost-efficient production and/or to a reduced variety of parts can be obtained in particular. In addition, a high degree of operational reliability and/or a high level of operating comfort can be obtained. In an advantageous manner, maintenance that is simple and/or quick to carry out is made possible. In particular, a life vest bag which is easily fillable and/or can easily be tested for a correct state can be provided.
The life vest bag advantageously comprises at least one seal which is configured for the purpose of indicating the correctly closed state. In particular, the seal is configured to be damaged at least in part when the access opening is opened. The seal preferably comprises at least one closure which is configured for fixing, in particular mechanically, a state of the closure unit in the correctly closed state. For example, the seal can comprise at least one adhesive seal and/or at least one adhesive film and/or at least one plastic film and/or at least one lead seal and/or at least one bolt and/or at least one pin and/or at least one split pin. It is conceivable for the seal to be connected in one piece to the closure unit. As a result, it is possible to recognize a correct and/or an incorrect state of the life vest bag quickly and/or reliably.
A further design of the invention proposes that the life vest bag comprises at least one, in particular the, seal which is configured to be at least damaged when an object, which comprises a cross section with a cross-sectional area of more than 2 cm2, in an advantageous manner of more than 1 cm2 and in a particularly advantageous manner of more than 9 mm by 9 mm, is pushed into the receiving space. As a result, it is possible to avoid inserting larger objects and/or potential damage or destruction of a life vest.
An advantageous design of the invention proposes that a cross section of the access opening in the correctly closed state deviates from a cross section of the access opening in the open state. In particular, a cross section of the access opening in the correctly closed state is smaller than in the open state. The closure unit is preferably configured for the purpose of deforming the receiving unit, in particular the access opening, in the closed state at least in part. For example, the receiving unit can be realized at least in part, advantageously entirely, as a sack and/or a bag and in particular can be realized so as to be deformable in a damage-free manner. Structural simplicity can be advantageously made possible as a result. Furthermore, tight and/or complete closing can be made possible as a result. In addition, space-saving geometry can be provided in an advantageous manner.
A particularly advantageous design of the invention proposes that the closure unit comprises at least two closure elements which close the access opening in the correctly closed state. The closure elements are preferably connected to one another, in particular at least in pairs, advantageously in a captive manner, in particular in the correctly closed state and/or in the open state. In particular, in the event of opening, a connection between the closure element is released at least in part, for example on at least one side of the closure element. In particular, the closure elements can be connected to one another integrally. It is conceivable for the closure elements, in particular in a state when connected to one another, to be configured for the purpose of deforming the access opening at least in part. A more reliable closure and/or a mechanism which is simple to operate and/or is more reliable can be advantageously provided as a result.
A preferred design of the invention proposes that the closure elements are connected to one another in an articulated manner, in particular at least in pairs. The closure elements preferably realize a frame encompassing the access opening at least in part. For example, the closure elements can each realize part of a joint. It is, in particular, conceivable for the closure elements to be connected to one another by means of a film hinge and advantageously integrally. However, it is also conceivable for the closure unit to comprise at least one articulated element which connects the closure elements together in an articulated manner, preferably at least in pairs. A high level of operating comfort and/or simple handling and/or a high level of reliability can be obtained as a result.
A particularly preferred design of the invention proposes that in the correctly closed state the closure elements are connected to one another by means of at least one positive locking connection, in particular a latching connection. The closure elements are preferably connected to one another along at least one first side, in particular in an articulated manner. In a particularly advantageous manner, the closure elements are connected by means of the positive locking connection along at least one second side. In an advantageous manner, at least one of the connecting elements comprises at least one latching lug and in particular realizes the same. The closure unit preferably comprises at least one actuating element which is connected in particular to at least one of the closure elements, advantageously integrally, and is configured for the release of the positive locking connection by a user. A more reliable and/or solid and/or where required easily releasable connection can be provided advantageously as a result. In addition, simple opening is made possible advantageously as a result.
It is further proposed that the closure unit comprises at least one spring element which is configured for supporting, at least in part, an opening of the access opening. In particular, the spring elements can be realized as a helical spring or as a spiral spring or as a leaf spring or as a leg spring or as a conical spring, for example produced from a metal and/or a plastics material. The spring element can be a compression spring or a tensile spring. It is conceivable for at least one closure element of the closure unit to realize the spring element. It is additionally conceivable for the spring element to be connected, in particular integrally, to the receiving unit. The term “integrally” is to be understood, in particular, as being connected at least in a substance-to-substance bond, for example by means of a welding process, a gluing process, an injection process and/or another process which appears sensible to the expert, and/or is molded advantageously in one piece, such as, for example, as a result of production from a casting and/or as a result of production using a single or multiple component injection method and advantageously from one single blank. The spring element is preferably arranged between the closure elements. The spring element advantageously generates compressive forces which act on the closure elements and act in different, in particular opposite, directions. In a particularly advantageous manner, the spring element, in at least one operating state, in particular during opening, presses the closure elements in different directions, in particular apart from one another. Easy access to a life vest can be made possible in an advantageous manner as a result. This means, in particular, that a life vest is easily able to be removed, where necessary, by a nervous and/or excited and/or unfocused and/or distracted user.
The spring element is realized advantageously as a spring hinge encompassing the access opening at least in part, particularly advantageously entirely. By a first object “encompassing at least in part” a second object is to be understood, in particular, that there is at least one projection direction for which at least 80%, advantageously at least 90% and particularly advantageously 95% of the points of a projection of the second object lie inside a smallest convex polygon which encloses a projection of the first object. In particular, the spring hinge can comprise a first spring hinge piece and a second spring hinge piece which are connected to one another in a flat manner at least in portions, advantageously on two opposite sides of the access opening. The spring hinge preferably realizes an edge of the access opening, at least in portions, in a preferred manner entirely. The closure unit advantageously comprises at least one clamping element which deforms the spring hinge at least in part in the correctly closed state. In a particularly advantageous manner, the clamping element compresses the spring hinge in the correct state, as a result of which, in particular, the access opening is closed. The spring hinge is preferably connected integrally to the receiving unit. A small variety of parts and/or a simple design and/or a low weight can be advantageously achieved as a result.
An advantageous design of the invention proposes that the closure unit is fastened to the receiving unit by means of at least one clamping connection, in particular in a region of the access opening. A “clamping connection” is to be understood, in particular, as a connection at least by means of a positive locking closure and/or a non-positive locking closure. For example, the receiving unit can be clamped between the connection elements. As a result, structural simplicity and/or space-saving geometry can be advantageously obtained. In addition, advantageous characteristics with regard to a cost-efficient and/or simple and/or rapid production can be obtained as a result.
A particularly advantageous design of the invention proposes that at least a portion of the closure unit, preferably the entire closure unit, is realized so as to be removable from the receiving unit. In particular, with the closure unit in a removed state, the closure unit and the receiving unit are arranged in a contact-free manner. However, it is also conceivable, as mentioned above in particular, for the closure unit to be connected to the receiving unit by means of a connection element. In an advantageous manner, the closure unit is realized so as to be removable and/or separable from the receiving unit. In a particularly advantageous manner, the closure unit is configured for the purpose releasing the access opening at least in part, preferably completely, when the closure unit is removed from the receiving unit. Easy access to a life vest can be obtained advantageously as a result.
A preferred design of the invention proposes that the closure unit is connected integrally to the receiving unit. In particular, the receiving unit and the closure unit are realized at least in part, preferably entirely, from a plastics material and/or from a fabric. The receiving unit and the closure unit are preferably realized from at least one common, in particular curved and/or folded, plate and/or from at least one film, in particular from a plastics material. However, it is also conceivable for the receiving unit and the closure unit to be realized from metal, for example from at least one, in particular curved and/or folded metal sheet. Simple production can be made possible advantageously as a result, in particular without any need for sewing.
A further design of the invention proposes that the closure unit is fastened to the receiving unit by means of at least one zipper. One side of the zipper is preferably part of the closure unit. In a particularly preferred manner, a further side of the zipper is part of the receiving unit. In particular, the zipper runs along an edge of the access opening. The further side of the zipper preferably realizes the access opening at least in part, preferably to at least a large extent. The term “at least to a large extent” is to be understood, in this case, in particular, as at least to 55%, advantageously at least to 65%, preferably at least to 75%, particularly preferred at least to 85% and particularly advantageously to at least to 95%. As a result, a life vest can advantageously be maintained and/or replaced, in particular without breaking the seal.
It is additionally proposed that the seal comprises at least two adhesive strips and at least one sealing strip which is glued onto the adhesive strip. An “adhesive strip” is to be understood, in this case, in particular, as a plastics material strip which comprises advantageous adhesive properties. The adhesive strips are preferably all formed from the same material. The adhesive strips are preferably formed from a hard plastics material. In principle, it is also conceivable for an adhesive strip on the one side of the access opening to be formed preferably from a different material to the adhesive strip arranged on the opposite side of the access opening. In this case, the two different adhesive strips are preferably formed from variously hard plastics material, the adhesive strip formed from a harder plastics material preferably increasing the stability of the life vest bag, whilst the adhesive strip formed from a softer plastics material comprises more advantageous properties for when the sealing strip is released. The adhesive strips, in this case, are preferably formed from a polycarbonate, a polyvinyl chloride (PVC) or from another plastics material that appears sensible to the expert. As a result, advantageous sealing of the access opening can be provided and the access opening can be, in particular, advantageously completely closed and insertion of objects without breaking the seal can be advantageously prevented. Advantageous specifications can be maintained in particular as a result.
In addition, a system having a life vest bag according to the invention and having at least one life vest arranged in the receiving space is proposed. A shape of the life vest and/or a type of collapsing and/or of folding the life vest is preferably adapted to the life vest bag. In a particularly preferred manner, with the life vest in a stowed state, a volume of the life vest corresponds at least substantially to a volume of the receiving space. The term “at least substantially” is to be understood in this context, in particular, as a deviation from a predefined value corresponding in particular to less than 15%, preferably to less than 10% and particularly preferred to less than 5% of the predefined value.
An advantageous design can be obtained, in particular, with a passenger seat, preferably an aircraft seat, with a life vest bag according to the invention. In particular, the passenger seat can comprise the system.
The life vest bag according to the invention is not to be restricted, in this connection, to the above-described application and embodiment. In particular, for fulfilling a functionality described herein, the life vest bag according to the invention can comprise a number which deviates from the number of individual elements, components and units named herein.

In principle, it would also be conceivable, however, for the sealing strips 134k to be realized in a transparent manner. The sealing strip 134k closes the access opening 16k completely. As a result, the life vest bag 30k can be realized in a completely closed manner in an unused state such that nothing is able to be inserted into the life vest bag. As a result, in particular new regulations which prescribe that no objects are able to be inserted into the life vest bag without breaking a seal are able to be maintained. The sealing strip 134k comprises an unsealing function, a clear feature being imaged on the sealing strip 134k after the sealing strip 134k has been removed once from the adhesive strips 126k, 128k, 130k, 132k. A readable message appears on the sealing strip once it has been removed for the first time, such as, for example, in particular the message “VOID” or “Unsealed” which is simple and unambiguous to recognize. The readable message which appears once the sealing strip 134k has been removed is preferably generated during the processing of the sealing strip 134k and is sufficiently known in the prior art.
The life vest bag 30k comprises a tab 102k which is attached to a bottom side of the access opening 16k on the bag 60k. In a closed state, the tab is arranged below the sealing strip 134k. The life vest bag 30k can be opened by pulling on the tab 102k. The access opening 16k closed by the loop and hook tapes is opened by pulling on the tab 102k. In this case, the sealing strip 134k is released at least in part from the adhesive strips 126k, 128k, 130k, 132k. As a result of realizing the adhesive strips 126k, 130k, 132k from a hard plastics material strip, the sealing strip 134k holds particularly well here and the bag 60k is endowed with particularly advantageous dimensional stability. Once the access opening 16k has been torn open by means of the tab 102k, a life vest which is arranged in the receiving space of the life vest bag is able to be removed through the access opening. After the sealing strip 134k has been released once from the bag, that is to say in particular from the adhesive strips 126k, 128k, 130k, 132k, the message that the sealing strip 134 has been released will always be recognizable. As a result of a corresponding design of the life vest bag 30k, a life vest arranged in the life vest bag 30k is particularly easy to remove. For opening the life vest bag 30k, in particular the access opening 16k, just a force of approximately 120 N is necessary to remove the sealing strip 134k and to open the access opening 16k as a result of separating the loop and hook tapes which are arranged there. Without the sealing strip 134k, even just a force of approximately 50 N is necessary to open the access opening 16k of the life vest bag 30k.
