AUTOMOTIVE SEAT BACK RECLINING MECHANISM

摘要

A recliner assembly (16) for providing pivotal movement of a seat back (14) relative to a seat cushion (12) includes a seat cushion bracket (18) secured to the seat cushion and a seat back bracket (22) secured to the seat back. A locking recliner mechanism (26) pivotally interconnects the seat back bracket to the seat cushion bracket. The locking recliner mechanism is operable between an unlocked condition for providing the pivotal movement of the seat back between a plurality of reclined positions and a locked condition for locking the seat back in any one of the reclined positions. A drive shaft (34) is coupled between the seat cushion bracket and the locking recliner mechanism for defining a seat back pivot bracket and rotating the locking recliner mechanism between the locked and unlocked conditions. An elongated release lever (56) has a first end (58) pivotally connected to the seat cushion bracket defining a release lever pivot axis (B) spaced laterally from the seat back pivot axis (A) and a second free end (6) forming a handle. An angular displacement link (68) has a first end (70) fixedly secured to the drive shaft (34) and a second end (74) rotatably coupled to the release lever (56) to define a link axis (C) spaced laterally from the seat back pivot axis and the release lever pivot axis. The link rotates the drive shaft and actuates the locking recliner mechanisms between the locked and unlocked conditions in response to the pivotal movement of the release lever about the release lever pivot axis.
