A vehicle seat comprises a seat cushion frame configuring a frame member of a seat cushion, and a seat unit that is supported by the seat cushion frame and on which an occupant sits, that has a higher seating face rigidity in a seat front-rear direction than a seating face rigidity in a seat width direction, and that has the seating face rigidity in the seat width direction set lower at a seat front-rear direction rear side than at a seat front-rear direction front side.

A seat system for a passenger aircraft. The seat system includes a passenger seat frame having at least one pair of generally parallel spar tubes laterally positioned across the passenger seat frame and an articulating seat pan assembly. In one embodiment, the articulation seat pan assembly includes at least two pairs of opposed crescent-shaped seat pan roller assemblies attached to the spar tubes and a seat pan adapted to be mounted onto the pairs of opposed seat pan roller assemblies whereby the seat pan articulates along the seat pan rollers from back to front of the passenger seat frame. The seat system may further include a seat back tray table attached to the back of the passenger seat.

A vehicle seat in which a net structure may be attached easily to a frame while ensuring rigidity of the seatback frame. In the vehicle seat, a net structure is drawn within a seat frame. The seat frame includes: a net frame in which the net structure is drawn, a receiving frame formed integrally with the seat frame, and a fastening mechanism that fastens the net frame to the receiving frame.

A vehicle seat in which a swiveling motion of a sub-frame is restricted only to a desirable direction is provided. A sub-frame is suspended from a seatback frame. A first elastic member connects a right upper end of the sub-frame to the seat back frame, and a second elastic member a left upper end of the sub-frame to the seat back frame. A universal joint mechanism connects a lower lateral portion of the sub-frame to a lateral member of the seat back frame.

The present invention relates to, among other things, a rotational damper comprising a fluid-filled damper housing and within the damper housing a piston rotatably accommodated by a rotation axis of the rotational damper in a first direction and an opposite second direction with a piston rod extending in the direction of the rotation axis; whereby the piston has at least one opening with a flow cross-section which allows for the flow of fluid through the piston, whereby a total flow cross-section is calculated as the sum of the flow cross-sections of the at least one opening. A blocking device can be furthermore assigned to the piston which is capable of reducing the flow cross-section of at least one of the openings during a rotation of the piston in a first direction relative to a rotation of the piston in the second direction.

A vehicle seat comprises a seat cushion frame configuring a frame member of a seat cushion, and a seat unit that is supported by the seat cushion frame and on which an occupant sits, that has a higher seating face rigidity in a seat front-rear direction than a seating face rigidity in a seat width direction, and that has the seating face rigidity in the seat width direction set lower at a seat front-rear direction rear side than at a seat front-rear direction front side.

A vehicle seat suspension system includes first and second side supports that define a seatback frame. A front trim piece is coupled between the first and second side supports. A suspension component is coupled with a central area of the front trim piece and has flexible members protruding forward and outward therefrom. A passenger support panel has a periphery coupled to distal ends of the flexible members and suspended away from the seatback frame.
