Seatbelt device for vehicle; has belt held on belt roller tensioned by spiral spring, with device to prevent belt from unrolling and belt guide device over passenger's shoulder to guide belt

摘要

The device has a belt (15) held on a belt roller (12), which is tensioned by a spiral spring and has a device to prevent the belt from unrolling when an accident causes acceleration. A belt guide device (17) with a guide roller (20) is arranged over a passenger's shoulder and guides the belt from the belt roller to secure the passenger. The guide roller is fixed to the vehicle chassis (11) and can slide vertically away from the passenger under the force of a spring, but is normally fixed by a holder mechanism (16) against the spring force. The holder mechanism releases the guide roller when there is a tension force on the belt due to an accident, so that the belt is pulled to return the passenger to the normal seating position.
