Abstract
A safety restraint system for an occupant of a vehicle seat provided with adjusting means for varying the seat position and/or seatback inclination. The system comprises a seat belt, a retractor having a reel constantly biased toward retraction of the belt and a tension-eliminating mechanism including an electric actuator for inhibiting the reel from turning in the belt-retracting direction when the seat belt is worn by the occupant to cause closing of a primary control switch. The improvement resides in the provision of secondary control switch(es) coupled with the seat adjusting mechanism to make the tension-eliminating mechanism ineffective during operation of the adjusting means, thereby allowing the occupant to accomplish adjustment of the seat without the need of unfastening the seat belt and automatically adjusting the amount of protraction of the belt from the retractor in compliance with the change in the position or posture of the occupant.
