ABSTRACT:
A seat belt apparatus is provided for restraining the occupant of a seat assembly within a vehicle body structure having a plurality of closure members each hingedly supported for movement between opened and closed positions to selectively open and close a respective utility opening. The closure members may be front and rear side doors, a hood or a trunk lid. The seat belt apparatus includes a length of flexible belt having fixed and free ends opposite to each other, an automatic belt retractor rigidly connected with the free end of the belt for forcibly winding up the belt thereby holding the belt under tension, a detecting system for detecting the movement of at least one of the closure members towards the opened position, a locking mechanism built in the automatic belt retractor for preventing the belt from being pulled outwards from the automatic belt retractor when a predetermined acceleration acts thereon, and a cancelling mechanism for disabling the locking mechanism when the detecting system detects the movement of the at least one of the closure members towards the opened position. Instead of the cancelling mechanism, a sensitivity reducing mechanism may be provided for lowering the sensitivity of the locking mechanism.
