<p>In a seat belt for use in a vehicle with a braking lever (21) engaging ratchet gears (32,32') for use as an emergency braking means, a seat belt winding force control device (1) is provided in which a braked means of ratchet gear (11) toothed contrary to said ratchet gears (32,32') is formed on the winding axis (5), and said braking means provided with a brake (12) which is elastically attached by a spring (13) is formed as the binding means of said braked means, and an intermittent snapping switch (18) or a solenoid is formed as the intermittent means of said braking means and said intermittent means (18) is operated by the belt snapping of the wearer. The winding force can be easily locked and released by snatching within the range in which the wearer does not feel a sense of oppression. Even when the belt is drawn out by the movement of the wearer after winding force is set, it returns to its original position within the given limits and so it can be adapted for wearer's movement to some extent. Being formed of a relatively simple mechanism, the device operates without trouble and enjoys a nearly permanent life. <IMAGE></p> |
