The invention relates to tray tables for passenger seats or the like.
Many passenger seats such as those on passenger aircraft, buses, trains, and the like are equipped with upright positions and full flat or a lie flat bed position. These seats comprise at least a bottom cushion, a back cushion, and armrests.
In an upright position, the top of the bottom cushion is typically located between 15-19 inches from the floor, and the top of the armrests is located at approximately 25 inches from the floor.
In an sleeper position, the top of the bottom cushion is generally at the same level, and the body of the passenger is located just below and/or adjacent the armrest.
Many seats are double or triple units, with a center console between each seat. The center console serves many functions: separation between passenger living space, armrest support, food tray stowage compartment, and/or location for a drink tray.
Typically, a tray table stowage compartment is located inside the center console, below the armrest or in front of the center console below the drink tray. These stowage locations are limiting to the amount of room available for a passenger when the passenger seat is in the sleeper position.
In certain situations, it may be desirable to maximize the amount of space available to passengers when the passenger seat is in the sleeper position by relocating the tray table stowage compartment to a location above the armrest and/or by retracting at least one of the armrests.
Embodiments of the present invention include a tray table assembly comprising a table body, a support arm comprising a support portion coupled to the table body and a coupling portion, a center console comprising a table storage compartment and a track, wherein the track is located between the table storage compartment and a location forward of the table storage compartment, and the table storage compartment is located above an armrest support, and a linkage comprising a head and a base, wherein the head is rotatably coupled to the coupling portion of the support arm, and the base is slidingly coupled to the track, wherein the table body is configured to slide between a stowed position within the table storage compartment to a raised position in the location forward of the table storage compartment, and an outer surface of the table body is substantially vertically oriented in the stowed and raised positions, and wherein the table body is configured to rotate between the raised position and a deployed position forward of a passenger seat, and the outer surface of the table body is substantially horizontally oriented in the deployed position.
In certain embodiments, the center console further comprises a drink tray located forward of the raised position, and the table body may be configured not to contact the drink tray. A retractable armrest may be positioned proximate a seat back, and a control panel may be located on the head of the linkage.
According to certain embodiments, the track is located below an upper surface of the armrest support. In some embodiments, the passenger seat comprises additional width when positioned in a sleeper position.
The described embodiments of the invention provide tray table assemblies for use with passenger seats. While the tray table assemblies are discussed for use with aircraft seats, they are by no means so limited. Rather, embodiments of the tray table assemblies may be used in passenger seats or other seats of any type or otherwise as desired.
The table body 12 may be formed of materials including but not limited to aluminum, stainless steel, aramid fibers, polycarbonate, polypropylene, other plastic materials, other metallic materials, composite materials, or other similar materials. One of skill in the art will understand that any suitable materials may be used to form the table body 12 that will provide a lightweight table body 12 having sufficient strength to withstand forces that may be placed on the tray table assembly 10.
The support arm 14 and the linkage 16 may be formed of constructed of any suitable material including but not limited to aluminum, stainless steel, other metallic materials, composite materials, or other similar materials that provides sufficient strength to withstand forces that may be placed on the tray table assembly 10.
In some embodiments, as illustrated in
In some embodiments, as shown in
The coupling portion 20 may be coupled to or integrally formed with an end 24 of the support portion 18. In some embodiments, as illustrated in
The linkage 16 may further comprise a base 30 coupled to or integrally formed with the head 28. In certain embodiments, the head 28 may comprise a cross-sectional area having a circular shape so that the head 28 may have a conical or cylindrical three-dimensional shape and any suitable shape that allows the coupling portion 20 to rotate relative to the head 28. The head 28 is therefore configured to extend through the aperture 26 so that the coupling portion 20 rotates about the head 28. The head 28 may be oriented at any suitable angle relative to the base 30 so as to achieve the desired plane of rotation of the table body 12.
The combined orientation of the head 28 and/or the shape of the coupling portion 20 control the rotational pattern of the table body 12. Specifically, as illustrated in
In some embodiments, as shown in
In the embodiments shown in
In certain embodiments, as illustrated in
The table body 12 slides along the track 40 between the raised position where the table body 12 is positioned with the outer surface 36 in a substantially vertical orientation proximate one side of the passenger seat 34 (as shown in
A stop 68 may be provided adjacent a forward end of the track 40 that corresponds to the raised position of the table body 12 described above. The stop 68 prevents the table body 12 from traveling forward beyond the raised position location and contacting or interfering with the drink tray 46.
In the stowed position described above, the table body 12 may be housed within the table storage compartment 52. The table storage compartment 52 is configured to have a volume that accommodates substantially all of the surface area and the height of the table body 12 in the stowed position. For example, in some embodiments, the table storage compartment 52 may be configured to house the table body 12 in an unfolded configuration, such as in the examples where the table body 12 is formed as an integral piece. In embodiments where the table body 12 comprises multiple segments that are folded over one another for stowage, the table storage compartment 52 may include a wider opening to accommodate a greater thickness of the folded table body 12 and a smaller height to accommodate a shorter vertical dimension of the folded table body 12. One of ordinary skill in the relevant art will understand that any suitable configuration of height and depth of the table storage compartment 52 may be used that will fit within appropriate space above and/or within the center console 44.
The shape of the head 28, the coupling portion 20, the shape of the table body 12 and/or the location of the stop 68 result in a rotational design for the tray table assembly 10 that is easily deployed and stowed, while also avoiding contact with the drink tray 46 or objects that may be placed on the drink tray 46 to prevent unintentional spills or accidents.
Furthermore, by locating the table storage compartment 52 and the track 40 approximately level with or above the armrest support 42, additional width is provided for a passenger when the passenger seat 34 is in a sleeper position.
The embodiments illustrated in
The passenger seat 34 may further comprise a retractable armrest 54 positioned opposite the location of the armrest support 42. The armrest 54 is slidingly coupled to a track 56 or other guiding means positioned proximate and/or aft of the seat back 50 of the passenger seat 34. The armrest 54 may slide to a deployed position where a forward edge 58 of the armrest 54 is positioned proximate a forward edge 60 of a lower cushion 62 of the passenger seat 34 when the passenger seat 34 is in an upright position. In the deployed position, the armrest 54 provides privacy to a passenger, as well as support for the passenger's arm.
In contrast, the armrest 54 may slide to a retracted position where the forward edge 58 of the armrest 54 is positioned proximate a forward surface 64 of the seat back 50 of the passenger seat 34 when the passenger seat 34 is in an upright position. In the retracted position, better access to the passenger seat 34 is available for handicapped access and/or for passengers requiring additional space to access the passenger seat 34. The retracted position also provides additional width for a passenger when the passenger seat 34 is in a sleeper position.
The foregoing is provided for purposes of illustrating, explaining, and describing embodiments of the present invention. Further modifications and adaptations to these embodiments will be apparent to those skilled in the art and may be made without departing from the scope or spirit of the invention.
