ABSTRACT:
A safety seatbelt retractor for use in a vehicle including a frame adapted to be fixed to the vehicle and a winding shaft rotatably mounted on the frame. The seatbelt is normally wound around the winding shaft. The winding shaft has associated therewith a spring member. When the seatbelt is unwound out of the winding shaft, the spring member applies no or weak biasing force to the winding shaft in such direction as to cause the seatbelt to be wound therearound. During the normal fastening of the seatbelt on a passenger taking his seat of the vehicle, the spring member continuously applies a weak biasing force to the winding shaft in the direction mentioned above. The winding shaft has also associated therewith a drive unit which, when operated, drives the winding shaft to rotate the same so as to cause the seatbelt to be wound around the winding shaft. The drive unit is operated when the seatbelt is unfastened or the passenger gets off the vehicle with the seatbelt unwound out of the winding shaft.
