Abstract

A belt shortening device for winding and unwinding a vehicle seat belt is disclosed. The device includes a 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 seat belt, when folded, is insertable into the longitudinally extending slot via the laterally extending entry opening. Once the vehicle seat belt is positioned within the longitudinally extending slot, the crank arm is manipulated to, thereby, rotate the spindle to wind the belt therearound. The laterally extending entry opening is positioned substantially mid-way along the length of the longitudinally extending slot to prevent ejection and slippage of the belt during winding.
