ABSTRACT:
A spindle has belt webbing wound thereon. The spindle is supported for rotation in belt withdrawal and belt retraction directions. A pawl member is movable from a first position allowing rotation of the spindle to a second position blocking rotation of the spindle in belt withdrawal direction. An inertia member is supported for rotation with and relative to the spindle. The pawl member is moved to its second position in response to rotation of the spindle in the belt withdrawal direction relative to the inertia member. Rotation of the inertia member is blocked in response to rotation of the spindle in the belt withdrawal direction a predetermined amount to enable the spindle to rotate in the belt withdrawal direction relative to the inertia member and thereby effect movement of the pawl member to its second position.
