Abstract
A vehicle seat belt retractor having an emergency locking mechanism of two seat belts is disclosed. There is provided a seat belt retractor with an emergency locking mechanism which comprises: a common U-shaped housing; a pair of seat belt retracting shafts, each having one end journalled on one plate of the common U-shaped housing and the other end connected with a return spring for biasing the retracting shaft to retract the corresponding seat belt; a pair of ratchet wheels each fixed to one end of the corresponding seat belt retracting shaft; an inertia sensor, mounted within said common U-shaped housing, for operatively detecting and signalling by displacement when the vehicle's inertia force exceeds a predetermined value; a lock pawl mechanism mounted within said common U-shaped housing and biased away from engagement with the ratchet wheels by means of a fixing means located at one plate of the common U-shaped housing; and an actuating lever rotatably fixed on the common U-shaped housing for actuating the lock pawl mechanism to simultaneously engage with both ratchet wheels when the inertia sensor detects and signals the vehicle's inertia force exceeding the predetermined value.
