Abstract: An acceleration switch that improves detection sensitivity without being enlarged. The acceleration switch includes a switch body, a fixed electrode arranged in the switch body, and a movable weight arranged in the switch body. The movable weight is displaced when subjected to acceleration. The movable weight includes a movable electrode that contacts the fixed electrode when the movable weight is displaced, and a pair of beams connecting the movable weight and the switch body. The beams pivotally support the movable weight and extend into recesses formed in the movable weight.

Abstract: An anchor plate engaging one end portion of an occupant restraining webbing is driven by a driving member movable along a guide rail provided on the vehicle body, whereby the webbing is automatically fastened to the occupant. A lock pawl of a locking plate pivotally supported by the vehicle body lock said anchor plate so as to support a tensile force of the webbing by the vehicle body in an emergency of the vehicle. A release block secured to the driving member rotates the locking plate, whereby the locking plate is disengaged from the anchor plate, so that the anchor plate become movable.

Abstract: A seatbelt retractor including a means for preventing excessive tightness of the seatbelt during use. The seatbelt retractor including a frame, a seatbelt take-up spool having a torque applied thereto in a wind-up direction and rotatably coupled to the frame, at least one ratchet gear coupled to the take-up spool, a pawl pivotally coupled to the frame and engageable with the pawl gear such that the spool is prevented from winding up when the pawl engages with the ratchet gear, and a means for disengaging the pawl from the ratchet gear when the seatbelt is completely wound on the spool or so long as the seatbelt is being pulled out from the wound up state and for engaging the pawl with the ratchet gear when the seatbelt is being utilized.

Abstract: A current limiting element for preventing electrical overcurrent manufactured by mixing conductive particles with an elastic insulating material which possesses a positive coefficient of thermal expansion, such that particles are normally in electrical contact with each other, and the elastic material interposed between the particles is caused by heating to expand so that the electric circuit is interrupted.

Abstract: A seat belt retractor system of the type wherein two seat belts are wound up on a single retractor shaft one over the other. The retractor includes a base, a retractor shaft rotatably supported by the base and a fastening means provided on both seat belts whereby the seat belts are easily fastened together when the seat belts contact each other during retraction and are easily separated when the seat belts are separated during extension.

Abstract: A lock assembly having special utility for locking sliding doors and the like is disclosed. The lock assembly comprises a cylinder lock having a rotor case and a rotatable rotor disposed therein. The rotor has pin members configured such that upon insertion of an associated key into the rotor, the pin members retract and the rotor is rendered selectively rotatable in the rotor case. A movable runner is coupled to the rotor and a hook member is coupled to the runner such that when the runner is moved from the unlocked position to the locked position, the hook moves into a "deadlock" zone. A driver member is also connected to the runner to aid it in moving from its locked position to the unlocked position and vice versa.
