RECLINING MECHANISM FOR AIRCRAFT PASSENGER SEAT

摘要

Provided is an improved reclining mechanism for an aircraft passenger seat. An aircraft passenger seat (100) is provided with a seat bottom frame (152) which constitutes a seat surface, and a seat back frame (162) which constitutes a back rest, wherein cam followers (240, 242) provided on both sides of the seat back frame (162) slide within cam grooves (132) on spreaders (130) supporting both sides of a seat mechanism. When an actuator (200) expands and pivots a link arm (230) in the direction of an arrow R1 to cause the seat back frame (162) to start reclining, a link plate (270) extends in the direction of an arrow F1, and pivots a head rest frame (172) in the ¸ direction. This operation prevents the line of sight of the passenger from being deviated from a video device provided on a back of a front seat.
