Retracting device for a safety belt

摘要

The retractor comprises a mandrel rotatably mounted on a support and around which the belt is wound. A spring biases the mandrel to rotate it in a direction to wind the belt onto the mandrel. Locking means are combined with the mandrel for preventing rotation of the mandrel. An acceleration detector is associated with the locking means to actuate the latter when the acceleration of the vehicle exceeds a predetermined value. A rocker is freely pivotably suspended from the support and the acceleration detector is carried by the rocker. The center of gravity of the rocker is offset from the axis of rotation of the mandrel.
