    Abstract: A retracting reel assembly including a cylinder with circular ratchet members secured to each end thereof for winding and unwinding a seat belt about the cylinder and a locking pawl movable into locking engagement with the ratchet members to prevent unwinding of the seat belt. The locking pawl is held out of locking engagement with the ratchet members by mechanical engagement with a catch in a leaf spring and the position of the leaf spring is controlled by a bimetallic strip. An electrical circuit is included to control the bimetallic strip so that the locking pawl is held out of locking engagement with the ratchet members for a predetermined time after the seat belt is moved in the unwinding direction whereby the seat belt may be extended and jockeyed back and forth by further extension and retraction until in the proper position before the locking pawl engages the ratchet members to prevent further unwinding of the seat belt.

    Abstract: THE HOLDER OF A SAFETY BELT IS CONNECTED TO A CABLE WHICH IS WRAPPED AROUND A SPRING-LOADED DRUM WHICH IS ROTATABLY SUPPORTED ON A CARRIER ATTACHED TO A VEHICLE SUCH THAT THE HOLDER CAN BE MOVED TOWARDS AND AWAY FROM THE CARRIER BY WINDING AND UNWINDING OF THE CABLE ON THE DRUM. A TOOTHED MEMBER ROTATES WITH THE DRUM AND IS ENGAGEABLE BY A SPRING LOADED PAWL TO LOCK THE DRUM WHEN THE PAWL IS ACTED BY AN ENERGIZED ELECTROMAGNET, THE LATTER BEING ENERGIZED BY CLOSING OF A SWITCH OF AN ENERGIZING CIRCUIT BY A SWINGING PENDULUM WHEN THE VEHICLE ACCELERATION OR DECELERATION EXCEEDS A PREDETERMINED MAGNITUDE.

    Abstract: A seat belt retractor includes a housing including a pair of side walls facing each other, a winding drum configured to wind up a webbing, a locking base prevented from being rotated in the pull-out direction, in an emergency of a vehicle, an impact energy absorbing member including a first end side coupled to the winding drum and a second end side coupled to the locking base, the impact energy absorbing member connecting the winding drum and the locking base so as to be integrally rotatable, in a normal state, at least one impact energy absorbing wire housed in at least one slot that is provided in the winding drum, and a stopper member configured to define an allowable amount of relative rotation between the winding drum and the locking base in a case where the impact energy absorbing member absorbs the impact energy.
