ABSTRACT:
A reel for safety belts. There is provided a safety belt for such use as motor vehicles or aircraft, which will normally have only light tension thereon to permit easy movement of the safetied person on the seat of the vehicle or aircraft but which upon sudden change in speed of the vehicle or aircraft will impose a sufficient strong restraint against unwinding thereof as to effect the desired support of the person to whom the safety belt is applied. The device is particularly adapted for fitting into relatively small spaces and is fully integrated for providing its operation without external connections. Particularly, the device embodying the invention is provided with a belt-carrying winch in which a spring maintains a light windup tension thereon. Acceleration sensitive means initially locks the winch to prevent unreeling of the belt and immediately thereafter releases said lock, winds the belt as needed to remove any slack therefrom and applies a brake against further unreeling of the belt.
