A system and method that comprises a plurality of inflatable tubes is provided. The plurality of inflatable tubes comprises a first tube set and a second tube set. The plurality of inflatable tubes is configured to provide a pressure distribution to an object supported by the plurality of inflatable tubes. The first tube set is configured to be inflated and deflated at a predetermined time interval to shift the pressure distribution.

The present invention is a portable, intelligent, ergonomically adjustable body-seat cushion controlled wirelessly via a smartphone or tablet app. Multiple air bladders embedded in the body-seat cushion inflate/deflate at the direction of the app to manipulate the physical position of the user's neck, back, posterior, legs, and feet in order to: (1) alleviate pressure on the back and sit-bones; (2) lengthen the user from a normal sitting position to a lengthened sitting position; and (3) increase blood flow to the user's extremities. Positioning algorithms in the app use the user's anthropometric data (body measurements) and seat measurements (including available space above and in front of the seat) to generate one or more air bladder fill instructions to lengthen the user. The app then wirelessly transmits the positioning instructions as well as optional motion, temperature, and vibration instructions to one or more wireless receivers in the seat cushion.

Described is a passenger seat that includes a seat bottom assembly (201) with a forward edge and a rear edge and a seat back assembly (101) extending up from the rear edge of the seat bottom assembly (201). The seat back assembly (101) may include a frame (103), a plurality of panels (104-107) within a perimeter of the frame (103), and at least one attachment member (161) configured to attach the plurality of panels (104-107) to the frame (103). The seat bottom assembly (201) may include a frame (203) and a plurality of panels (204,205,206) within a perimeter of the frame (103).

A cushion assembly has first and second foam layers that are fixedly connected to each other so as to be contiguous. The cushion assembly also includes a fire-retardant covering and finds particular use as the seat base of a vehicle seat, especially an aircraft seat.

A seat pan for a passenger seat and a passenger seat. The seat pan is corrugated for partially absorbing a downward loading applied to the seat pan through deformation of a corrugation pattern of the seat pan as a result of a counter force applied by a support structure of the passenger seat.

The present invention provides a cover for a seat in an aircraft or spacecraft, including a receiver which is configured to receive in an exchangeable manner an electronic device which is fitted with a screen, at least one recess being provided in the region of the receiver such that the screen of the electronic device is exposed for viewing.

Described is a seat back comprising a rear wall bordered by side walls projecting forward from the rear wall. The rear wall and side walls define a cavity in front of the rear wall and between opposing surfaces of the side walls. The seat back comprises an insert disposed at least partially within the cavity which is for supporting the back of a person leaning against the front of the seat back. The seat back and insert are shaped such that when the insert is positioned within the cavity, movement of the insert towards the base of the seat back is restricted.

Described are lightweight headrests with a perimeter frame 200 with an open central region. The open central region is spanned by a suspension membrane 100 held in tension. The suspension membrane provides support and cushioning functions to a passenger head without the need for internal structures or compression cushions. The perimeter frame of the headrest may have additional cross members spanning the rear portion of the headrest. These cross members may provide additional structure or locate attachment points for the headrest onto the seat.

A modular monocoque backrest is provided. The modular monocoque backrest may comprise a front shroud, a back shroud, and an at least one back spar. The front shroud may be coupled to the back shroud, and the back spar may be configured as a mounting point, enabling the modular monocoque backrest to mount to an aircraft floor. The front shroud and the back shroud may comprise a carbon fiber composite material, allowing the modular monocoque backrest to be modular in nature. The carbon fiber composite material may enable the modular monocoque backrest to have a lightweight design while also maintaining resistance to dynamic crash loads.

A vehicle seat for a passenger, comprising a backrest having a front face directed towards the passenger and a rear face opposite the front face, and a seat part having an upper face directed towards the passenger and a lower face opposite the upper face, wherein the rear face of the backrest and/or the lower face of the seat part comprise(s) at least one area that is deformable in the event of an impact, towards the front face of the backrest and/or towards the upper face of the seat part respectively, and in that the front face and rear face of the backrest, and/or the upper face and lower face of the seat part are located at a distance from each other, at least at said at least one deformable area, so as to define a clearance space, said at least one deformable area of the rear face of the backrest and/or of the lower face of the seat part being configured so as to deform into the clearance space in the event of an impact on the rear face of the backrest and/or the lower face of the seat part, without transmitting the impact to the front face of the backrest and/or the upper face of the seat part respectively.
