ABSTRACT:
The vehicle-sensitive retractor has an upper pendulum assembly and a lower pendulum assembly. The upper pendulum assembly includes a trunnion, a swivel axis for the trunnion, a support member for the trunnion, and a pendulum housing which is attached to the trunnion and is part of the upper pendulum assembly. The lower pendulum assembly includes a pendulum head, a pendulum rod and a pendulum weight. The trunnion of the upper pendulum assembly has an aperture in its bottom central portion through which the pendulum rod of the lower pendulum assembly extends. The trunnion has a circular support edge upon which the pendulum head of the lower pendulum assembly is disposed for pivoting movement. The trunnion is adapted to pivot in two directions upon its swivel axis with reference to the support member. The lower pendulum assembly and the upper pendulum assembly form a double pendulum mechanism. The upper pendulum assembly is adjustable to a variety of operable static positions in one plane according to the position in which the retractor is installed in the vehicle. The retractor may be tilted for installation without having to redesign the pendulum assembly and support assembly.
