Abstract: An entertainment seat (10) including a seat back (18) and seat base (24) having a seat architecture for providing structural support relative to a base (floor) and also having two seat motion actuators (92, 94) located toward the front of the seat (10) for providing seat movement in response to a seat motion control system (16) for operating the seat motion actuators (92, 94), the seat (10) also includes armrests (26, 28) which form a portion of the seat back (18).

Abstract: A back frame for a vehicle seat assembly having an upright frame member capable of supporting compressive and tensile loading and a secondary, tensile load carrying member capable only of supporting significant loads in tension. The tensile load carrying member is attached to the upright frame member at the upper end of the back frame and extends downward behind the upright frame member and is attached to a base at the lower end of the back frame. The upright frame member is also attached to the base at the lower end of the back frame. The result is a triangular truss formed by the upright frame member, the tensile load carrying member and the base.

Abstract: A vehicle seat having at least one hinge fitting, the upper fitting element (10) of which is associated with the backrest (11) and the lower fitting element of which is associated with the seat frame, has a hook (14) which is arranged so as to be pivotable in a suspended manner, runs parallel to the hinge axle in its locked position, and securely engages behind lock bolts (29) to be connected with the floor of the vehicle. The upper fitting element (10) has a detent (28) in a surface (27) that extends in its pivot direction. A counter detent (22') is provided at one end of a double-armed pivot lever (20), which is pivotably mounted on the lower fitting element and is spring-loaded in the sense of moving the counter detent (22') toward the detent (28). The detent (28) and the counter detent (22') are in engagement in an angular position of the upper fitting element (10) that lies outside of the use position of the backrest ( 11), and form a form-fitting pivot block for the upper fitting element (10).
