Abstract
A seat belt winding apparatus for a vehicle comprises a winding reel and spring means having one end connected to the winding reel and the other end connected to a stationary part of the apparatus. The spring means is constituted by two spiral springs connected to each other though an interposed ratchet gear rotatably mounted on a stationary part of the apparatus. There is provided for controlling rotation of the ratchet gear controlling means which includes a pawl adapted to releasably engage with the ratchet gear, electro-magnetic means for selectively actuating the pawl and a switch which responds to the states of the vehicle to selectively energize the electro-magnetic actuator means, thereby to control the combined force of the first and second springs in dependence on whether the pawl is engaged with the ratchet gear or not and hence in dependence upon the prevailing states of the vehicle.
