Abstract
A vehicle-sensitive retractor is provided that can be mounted in a reclinable seat back which has a nominal position inclined to the vertical and that is actuated to a locked position in each of three mutually-perpendicular planes. The retractor has a universal acceleration sensor that compensates for different seat back inclinations so that it does not lock until a threshold vehicle acceleration condition is detected, and so that it will lock regardless of the sensed acceleration when the seat back and retractor are shifted to specified inclinations forward and rearward from the seat back nominally inclined position. The sensor preferably includes a weighted basket that supports an inertia member. At the rearward inclination position, the inertia member operates an actuating mechanism to lock the retractor. A stop engages and prevents adjustment of the support at the seat back's forwardmost inclined position so that at a predetermined angular distance forward therefrom, e.g. 22°, the inertia member causing locking of the retractor before reaching the specified forward inclination position from the design position where the retractor must be locked.
