Abstract
Each vehicle door in which a retractor is mounted includes a jamb switch mounted in the door jamb for sensing actual opening of the door, and a lock switch mounted in the door lock assembly for sensing actuation of the interior or exterior door handles. When door opening or closure is indicated, locking of the retractors is inhibited for a predetermined interval. Logical agreement between the lock and jamb switches is required to maintain the inhibit beyond the predetermined interval while the door is open. If agreement is not achieved within the interval, a switch failure is presumed, and the inhibit is removed to permit normal locking of the retractors. If such agreement is achieved, the inhibit is maintained until closure of the door, and thereafter for another predetermined interval. If the switches fail to remain in agreement after closure of the door, further operation of the inhibit on subsequent opening of the door is disabled.
