ABSTRACT:
An improved safety-belt retractor to be applied to an automotive vehicle or other vehicles for protecting a wearer from danger caused when the vehicle is suddenly or rapidly decelerated. The disclosed safety-belt retractor comprises a frame, a belt reel rotatably disposed within the frame and a safety-belt wound thereon to allow extraction and retraction of a safety-belt, a ratchet wheel with a plurality of ratchet teeth on the periphery thereof being secured on the belt reel, a locking member movably disposed within the frame opposing to the ratchet wheel and being engageable with the teeth of the ratchet wheel, and an inertia sensing means, including a means for operating the locking member, for interengagement of the locking member and the ratchet wheel so as to lock the extraction, when the vehicle is suddenly or rapidly decelerated. The improvement comprises, in combination, an inertia sensing means supported by a supporting means in horizontally rotatable position, the supporting means includes an elastic member for allowing displacement of the locking member when the latter is moved toward the ratchet wheel and which is deflected by a top of a ratchet tooth to a position apart therefrom, and for accumulating the reaction energy for elastically forcing the locking member toward the ratchet wheel for interengagement therewith.
