SEAT BELT RETRACTOR FOR RECLINABLE SEAT BACKS

摘要

A vehicle-sensitive retractor (10) is provided that can be mounted in a reclinable seat. The retractor has a universal acceleration sensor (12) that compensates for different seat back inclinations so that it does not lock until a threshold vehicle acceleration condition is detected. The sensor (12) includes a weighted basket (14) that supports an inertia member (18). At the rearward inclination position, the inertia member (18) operates an actuating mechanism (20) to lock the retractor. A stop (22) engages and prevents adjustment of a support at the seat back's forwardmost inclined position, so that the inertia member (18) causes locking of the retractor (10) before reaching the specified forward inclination position from the design position where the retractor must be locked.
