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 fore and aft, laterally- extending beam tubes (32, 34); (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: (i) a recline arm pivotally-connected proximate a first end to the seat back assembly and pivotally-connected proximate a second end to a first end of a crank link; (ii) the crank link pivotally connected at a second end remote from the recline arm to the seat pan for allowing the recline arm to drive the crank and transfer motion of the seat back between upright and reclined positions through the crank link to cause corresponding rearward and forward motions of the seat bottom assembly; (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) characterized in that the seat pan rails include forward and rear roller bearing assemblies pivotally mounted thereto and configured to ride along an outer, upper surface of the fore and aft beam tubes (32, 34) for articulating movement in response to pivotal movement of the recline arm. (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 fore and aft, laterally- extending beam tubes (32, 34); (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: (i) a recline arm pivotally-connected proximate a first end to the seat back assembly and pivotally-connected proximate a second end to a first end of a crank link; (ii) the crank link pivotally connected at a second end remote from the recline arm to the seat pan for allowing the recline arm to drive the crank and transfer motion of the seat back between upright and reclined positions through the crank link to cause corresponding rearward and forward motions of the seat bottom assembly; (i) a recline arm pivotally-connected proximate a first end to the seat back assembly and pivotally-connected proximate a second end to a first end of a crank link; (ii) the crank link pivotally connected at a second end remote from the recline arm to the seat pan for allowing the recline arm to drive the crank and transfer motion of the seat back between upright and reclined positions through the crank link to cause corresponding rearward and forward motions of the seat bottom assembly; (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) characterized in that the seat pan rails include forward and rear roller bearing assemblies pivotally mounted thereto and configured to ride along an outer, upper surface of the fore and aft beam tubes (32, 34) for articulating movement in response to pivotal movement of the recline arm.
