A belt shortening device for winding and unwinding a vehicle seat belt includes an L-shaped spindle mounted in a frame and connected to a crank arm to facilitate winding. The spindle includes a longitudinally extending slot which communicates with a laterally extending entry opening. A spring-biased closure is connected to the spindle to close the laterally extending entry opening during winding. When the closure is open and access to the laterally extending entry opening is available, a seat belt is insertable, edge first, into longitudinally extending slot via laterally extending entry opening. Once the vehicle seat belt is positioned within the longitudinally extending slot, the closure closes the entry opening and the crank arm is manipulated to, thereby, rotate the spindle to wind the belt therearound. The laterally extending entry opening is positioned at one end of the length of the longitudinally extending slot. A guide tab or pair of guide tabs may also be employed to further secure the belt during winding and unwinding.
