ABSTRACT:
A retractor lock and pawl saddle combination for seat belt retractors and particularly inertial retractors in which the saddle supports the pawl or lock and the saddle is deformably installed in the retractor frame dimensionally supporting and journalling the shaft of the retractor drum and having a deflective portion in support of the pawl so that as the pawl engages the ratchet wheel, a portion of the saddle flexes guidably and the pawl is carried to thrust and lock abutment against the retractor frame. The flexing portion of the saddle supports an inertial sensor such as a pendulum and the pendulum upon movement pivots the pawl to engage the ratchet wheel. The saddle pawl and sensor are preassembled and are then sprung into place between the upstanding walls of the retractor frame.
