Car seat-belt retract system A blade wheel 17 on the spindle 11 for reeling the seat belt 12 can be rotated with its blades 18 in a groove 24 designed to guide a ball 27. A rest position 28 is arranged for the ball in the said guide groove, and on one side of the rest position there is a limit stop 30 for the ball. A hollow 31 is located at the bottom of the guide groove between the rest position and the limit stop. With the drawing-out of the seat belt 12 and the rapid rotation of the spindle 11, the ball 27 is carried over the hollow 31 against the stop 30. In the case of slow rotation of the spindle, the ball will avoid contact with the blade wheel 17 in the hollow 31 and will return to the rest position. On the other side of the rest position 28, the ball allows free movement of the blade wheel. <IMAGE> |
