Patent Application
20190291870
The present application relates to a storage portion for a passenger seat. Particularly, although not exclusively, the present application relates to a storage portion that is intended to form a storage pocket or compartment in conjunction with a surface of a vehicle seat such as an aircraft seat. The present application also relates to an aircraft seat having a storage pocket.
Many passenger seats that are installed in vehicles, such as aircraft, automobiles, or trains, are provided with a pocket or compartment for the storage of, e.g., literature, games, food and drink items, spectacles, and portable electronic devices. In a typical arrangement, the storage pocket is provided on the rear surface of a first seat in order to be accessible to a passenger occupying a second seat of the vehicle that is located behind the first seat and is spaced therefrom.
In the case of storage pockets that are intended for use on an aircraft seat, it is known for the storage pocket, or at least the portion of the storage pocket that forms a rearward facing surface of the seat, to be made from high strength, rigid plastic. This, in part, is for compliance with legislation concerning the installation of seats into an aircraft that seeks to protect occupants from head injury in the event of an impact with the seat in front. As will be appreciated, aircraft seats are typically arranged to define a plurality of rows with a particular spacing or distance between the rearward facing surface of a first seat and a second seat directly behind.
Specifically, there is legislation that states that a potential impact region of a rearward facing part of a seat must be strong enough to stay intact and/or not shatter during an impact event. As a consequence, it is known for storage pockets that are provided at an upper rearward facing region of an aircraft seat, i.e., the region that extends from the top of the seat and comprises the upper third or upper half of the back surface of seat and thus forms at least a part of the potential impact region of the seat, to be formed of rigid/hard plastic.
However, although the storage portion may be strong enough to withstand forces arising as a result of impact with a passenger who is occupying the seat behind, significant injury including head trauma may be suffered by that passenger. This problem is exacerbated in aircraft seating arrangements, where the spacing between adjacent rows of aircraft seats is kept to a minimum.
Furthermore, rigid or inflexible storage pockets have been shown to cause damage to items, particularly literature items, that are stowed in the pocket and that may collide with the hard edges of the pocket as the item is placed into the storage pocket.
The present examples are concerned with improving the design of a storage portion that is intended to be mounted to an upper rearward-facing portion of a vehicle seat. Embodiments of the present invention are particularly concerned with a storage portion that is intended to be provided at an upper rearward facing portion of an aircraft seat.
According to a first aspect of the present invention, there is provided an aircraft seat comprising a storage pocket provided on a rearward facing surface of the seat, the storage pocket comprising a storage portion that is detachably mounted to the seat in order to form the storage pocket, wherein the storage portion is formed of a flexible and/or deformable material.
The storage portion may be formed of a rubber-like material or elastomer. According to one or more examples, the storage portion is formed of a silicone, or a silicone-type, material. Thus, the storage portion may be formed of silicone rubber. The storage portion may be formed of a material having a Shore hardness that is between 50A and 60D, preferably between 60A and 100A, more preferably between 80A and 98A. The Shore hardness is selected having regard for the desire for the storage portion to be flexible and/or deformable, while also being able to retain its shape.
The storage portion may comprise an attachment mechanism for attaching the storage portion to the seat. For example, the attachment mechanism may comprise a plurality of mounting pins that are provided along one or more edges of the storage portion. The pins may be flexible. For example, the pins may be formed of rubber, such as silicone rubber, or from flexible polymer material.
The aircraft seat may comprise a plurality of recesses, such as holes or blind bores that are each configured to receive a cooperating mounting pin.
The pins may be formed with an enlarged portion that is larger in diameter than the recess, so that when the pin has been pushed through the recess in the seat and into a corresponding recess in the back of the seat, it recovers its original shape, thereby holding the pin in place and securing the storage pocket to the seat back.
If the pins are made of flexible material, they do not present a hazard to passengers in the seat to which the storage pocket is fixed or in the seat behind, in the event of a collision.
The storage pocket may comprise a primary opening towards an upper region of the storage pocket for passing items into an interior enclosure of the storage pocket. The primary opening may be a literature opening and may, for example, be at least 210 mm wide so that it can accommodate an A4 note pad. It may be as wide as the storage pocket, so the width may typically be in the range of 200 mm to 300 mm. The storage pocket may also comprise a secondary opening at a position below the primary opening. The secondary opening is also for passing items into the interior enclosure of the storage pocket and also allows a passenger and flight crew to view what is in the storage pocket.
The secondary opening may be elongate. For example, the secondary opening may be 50 mm to 300 mm wide and 10 mm to 75 mm high.
The storage portion may comprise a back portion. The secondary opening may be formed in the back portion. The storage portion may comprise first and second side portions that extend in a direction having a component which is orthogonal with respect to the back portion. The storage portion may comprise a base portion that extends in a direction having a component which is orthogonal with respect to the back portion. The base portion may comprise at least one tertiary opening for allowing, e.g., debris to fall through the pocket, for example, during cleaning of the storage pocket. The or each tertiary opening may be at least 10 mm wide.
According to one or more examples, the storage portion exhibits a single piece construction. The storage portion may be formed of a single piece of molded material. The material may be an elastomer or rubber-like material, such as silicone or silicone-rubber.
Features of any given aspect may be combined with the features of any other aspect, and the various features described herein may be implemented in any combination in a given embodiment.
Various aspects of this invention will become apparent to those skilled in the art from the following detailed description of the preferred embodiment, when read in light of the accompanying drawings.
The back portion 21 of the storage portion 10 defines an outer, generally planar, surface of the storage portion 10. Optionally, and as illustrated in this particular example, the back portion 21 may be provided with a secondary aperture 24 that extends through the back portion 21 between the outer and inner surfaces of the back portion 21, provides access to an interior of the storage portion 10, and allows the interior of the storage portion 10 to be viewed from outside the storage portion 10. The secondary aperture may be at least 10 mm high and at least 50 mm wide so that articles, such as spectacles, pens, packs of tissues, and sweets can be placed in the storage portion 10 through the second aperture. The second aperture may be higher and wider. For example, the second aperture may be from 10 to 75 mm high and from 50 to 300 mm wide.
Other attachment mechanisms are envisaged within the context of the present invention including, for example, a plurality of openings provided at or near a perimeter edge of the storage portion 10 that are each sized to receive a protrusion correspondingly provided on the vehicle seat, or to align with holes formed in the seat and be connected by fixings such as rivets, bolts or screws.
As illustrated in
Furthermore, when the storage pocket is washed, the tertiary opening allows air flow through the pocket to speed up the drying process.
According to one or more examples, the storage portion 10 is detachably mounted to the seat 40 along a plurality of mounting edges. As illustrated in
According to one or more examples of the present invention, the storage portion 10 forms a storage pocket in conjunction with a region of an outer surface of a vehicle seat. The region of the outer surface of the seat effectively forms an interior surface of the storage pocket. The storage portion 10 can be considered to define an outer surface of the storage pocket and another interior surface of the storage pocket.
In an alternative embodiment, not illustrated, the storage pocket is a self-contained unit molded as a single unit with a front wall, a back wall, side walls, and a base wall.
Following attachment of the storage portion 10 to an aircraft seat, the resulting storage pocket preferably comprises a primary opening 28 to allow items to be loaded into the pocket. For example, as illustrated in
The first and second interior surfaces of the storage pocket 10 define an enclosure within which one or more items may be placed. It will be appreciated that the shape and size of the enclosure will depend at least partly on the design of the storage portion 10. For example, the storage portion 10 illustrated in
Other designs are envisaged within the context of the present invention in which, for example, the storage portion is configured to be more closely conformal with the outer surface of the seat. As a consequence of the flexible and/or deformable properties of the storage portion 10, which allows the storage portion 10 to deform in order to accommodate a given item, the storage portion 10 may be configured to have a lesser thickness than rigid storage portions having an equivalent capacity. Thus, examples are envisaged in which the storage portion 10 comprises only a back portion and does not comprise side portions or base portions.
According to one or more examples, the mounting mechanism is configured to allow the storage portion 10 to be readily detached, thereby allowing replacement and/or cleaning of the storage portion 10. For example, where the mounting mechanism comprises flexible pins, the pins can be withdrawn from corresponding fixing holes formed in the seat back by pulling firmly on the storage portion 10.
The opacity and/or color of the flexible storage portion 10, which may preferably be formed of silicone material, may be customized. According to one or more examples that utilize a silicone rubber material for the storage portion 10, one or more additives may be incorporated into the material that impart anti-bacterial, anti-microbial, or anti-mold properties to the material.
According to one or more example, the storage portion 10 is sized relative to the dimensions of the aircraft seat. Thus, the storage portion 10 may be mounted at or within a few centimeters of the edge of the seat so as to extend across the width of the rearward facing surface of the seat. This advantageously allows the storage capacity of the storage pocket to be maximized with respect to the size of the seat. For example, the storage portion 10 may be configured to allow an A4-sized literature item to be stowed entirely within the storage pocket in a landscape orientation. In one example, the storage portion 10 is configured such that the edges of the storage portion 10 are substantially flush with the side edges of the seat.
According to one or more embodiments, at least a part of the storage portion 10 is provided within a potential impact region of the seat, i.e., a region where a passenger occupying a seat directly behind the seat will tend to impact when exposed to a force that causes the occupant to be thrust towards the seat. As illustrated in
Examples described herein provide a storage portion 10 that exhibits a number of advantages over previously considered storage portions that are made from rigid plastic. Importantly, the softness and/or compliance of the storage portion 10 offers improved protection against trauma or injury to a passenger who may be subjected to forces which cause them to impact the seat in front.
Furthermore, the flexibility and/or deformability of the storage portion 10 allows the storage portion 10 to deform in order to accommodate one or more items, thus giving the potential for a small amount of “additional” or flexible capacity within the storage pocket. Furthermore, any item that exerts a force causing a slight deformation of the storage portion 10 will experience a degree of grip, or counter force, to thereby hold any such item securely within the storage pocket. In addition, items placed within the storage pocket are less likely to be damaged as a result of contact with the flexible storage portion 10.
Consequently, as the storage pocket is made from flexible material, a larger item such as a book, which is slightly too big to fit through primary or secondary openings, can still be eased into the storage pocket because the sides of the primary or secondary opening will flex slightly. Furthermore, an electronic device can be inserted into the primary or secondary opening, such that it is gripped by the sides of the opening and can be held in this way so that the screen can be viewed by the passenger hands free.
The hardness level of the material is preferably selected such that the deformable storage portion 10 substantially retains its shape and/or is resistant to sag over time.
It should be noted that the above-mentioned embodiments illustrate rather than limit the invention, and that those skilled in the art will be able to design many alternative embodiments without departing from the scope of the appended claims. The word “comprising” does not exclude the presence of elements or steps other than those listed in a claim, “a” or “an” does not exclude a plurality, and a single feature or other unit may fulfil the functions of several units recited in the claims. Any reference signs in the claims shall not be construed so as to limit their scope.
The principle and mode of operation of this invention have been explained and illustrated in its preferred embodiment. However, it must be understood that this invention may be practiced otherwise than as specifically explained and illustrated without departing from its spirit or scope.
