Abstract:
1. A passenger seat having a simultaneous rearward movement of a seat back assembly with a compensating forward and upward movement of a forward end of a seat bottom assembly so that the passenger maintains a similar angle between the upper and lower body in both an upright and reclined seat back position, comprising: (a) a seat back assembly and a seat bottom assembly supported by a frame mounted on laterally spaced-apart legs for being mounted to a deck of an aircraft, the frame including laterally-extending forward and rear beam tubes; (b) first and second laterally-spaced seat pan rails carried by the seat bottom assembly for supporting a seat pan; (c) a pivot linkage, comprising: (d) the seat pan rails defining respective downwardly-facing, shaped contact surfaces proximate a forward end thereof for riding on an upwardly-facing surface of the forward beam tube, the shaped contact surface adapted to lift the seat pan during forward movement of the seat pan, and lower the seat pan during rearward movement of the seat pan, thereby simultaneously raising and shifting forward the seat pan as the seat back assembly reclines and simultaneously lowering and shifting rearward the seat pan as the seat back assembly moves from the reclined position to the upright position; and (e) the seat pan rails having forward and rear roller bearing assemblies pivotally mounted thereon riding on an outer, upper surface of the forward and rear beam tubes for articulating movement in response to pivotal movement of the recline arm.
