Abstract
A strap retractor assembly of a vehicular seat belt arrangement including a retaining strap to be fitted to a vehicle occupant, comprising a reel shaft having the strap anchored thereto at one end of the strap, a spring urging the reel shaft to turn in a direction to have the strap re-wound on the reel shaft, a ratchet wheel rotatable with the reel shaft, a pawl member movable into and out of a position engaging the ratchet wheel and prohibiting the reel shaft from being turned in the aforesaid direction, a switch unit to produce first pulses in response to rotation of the reel shaft in one direction and second pulses in response to rotation of the reel shaft in the opposite direction, a pulse counter to count the first pulses forwardly and the second pulses backwardly, a comparator to compare the number of the pulses counted by the counter with a predetermined number of pulses and to produce a control signal when the former equals the latter, and a solenoid-operated actuator to drive the pawl member into the aforesaid position in response to the control signal.
