ABSTRACT:
A vehicle sensitive safety belt retractor is provided with actuating means responsive to acceleration of the vehicle for directly engaging with ratchet means mounted for interaction with a belt strap reel of the retractor, and thereby preventing protraction of the belt. The actuating means includes a unitary tipping inertia and locking member which is tippable from its position of rest so as to engage the ratchet means. The center of gravity of the unitary member passes over its pivot point on tipping of the member into locked position, so that it can only be returned to its stable, non-tipped position on movement of the ratchet means which it has engaged in a belt retraction direction. In one embodiment, a plurality of such unitary members are used in association with the single ratchet.
