The invention concerns an improvement in vehicle safety apparatus for sharply retracting a predetermined length of belt at the moment of an impending collision in order to draw the safety belt up firmly against the body of a passenger seated in the vehicle. In a vehicle safety belt take-up device of the type having an intermediate lug holding the safety belt and connected by means of a connecting rod to a piston arranged within a cylinder provided with a propellant charge for applying the belt retracting force when released in response to an actuating sensor, the improvement comprises a stationary backstop for stopping the retracting movement of the intermediate lug, and a locking device for locking the intermediate lug in place after the lug has retracted the belt a predetermined distance against the stationary backstop.

An improved safety belt take-up device of the type having a frame, a cylinder arranged on the frame, a piston displaceable within the cylinder, an intermediate lug holding the safety belt, a connecting rod connecting the intermediate lug to the piston, a propellant charge in the cylinder for applying the belt retracting force through displacement of the piston, and an actuating sensor for releasing the propellant charge upon sensing and impending collision, wherein the improvement comprises: a. stationary backstop means on said frame for stopping said intermediate lug when moved by said piston from a normal unactivated position to a retracted position against said backstop means, said retracted position being a predetermined distance from said normal unactivated position corresponding to the length of belt to be retracted; and b. locking means in conjunction with said backstop means for locking said intermediate lug in place after said lug has retracted the belt over said predetermined distance against said backstop means following release of said propellant charge.
