ABSTRACT:
A system for mounting a seat back relative to a seat bottom includes a rod having circumferentially spaced threaded and non-threaded portions. The non-threaded portions have a smaller diameter than the threaded portions. The rod extends through a bore in a lock ring. The lock ring bore has threaded and non-threaded portions. The threaded portions of the ring have a smaller diameter than the non-threaded portions. The lock ring is rotatable between a locked position at which its threaded portions are aligned with the threaded portions on the rod. At this position, the rod cannot move. The rod is fixed to a seat back pivot bracket, and when the rod is fixed, the seat back is prevented from pivoting relative to a seat bottom. However, when the locked member is rotated such that its non-threaded portions are aligned with the threaded portions on the rod, the rod can move. At this position the seat back can pivot relative to the seat bottom. The same locking mechanism is used as a seat track in a separate embodiment.
