Title: Self-locking belt reeling mechanisms
Inventor: VOIGT WILHELM
IPC: B60R22/40
Filed: 1983-03-02
Abstract: In a self-locking belt reeling mechanism, particularly for safety belts for motor vehicles, having a vehicle-sensitive locking system constructed as a ball or pendulum sensor, wherein the element sensitive to acceleration, namely the ball or pendulum, throws out a lever which engages in stop locations in a disc which locks the belt winding spindle when the sensor is activated, flexible material is provided in the region of the lever for noise attenuation, the noise problem is in the region of the tip (17) of the lever (14). Thus, when subjected to jolting, the tip of the lever may clatter over the toothed periphery of the disc (18) which causes blocking of the belt winding spindle and this may be a nuisance. To solve this problem, an annular attenuating member consisting of flexible material (22, 27), the periphery of which is struck by the lever (14, 17, 24) as it moves, is mounted on a component (18, 25) adjacent to the lever. <IMAGE>
