Abstract: A personal restraint system for a seat in a motor vehicle including a three-point belt system and a two-point belt system. The three-point belt system including a first belt retractor, and a first belt web having a first belt latch plate, and a first belt buckle. The two-point belt system including a second belt retractor, and a second belt web having a second belt latch plate, and a second belt buckle. The second belt retractor including a blocking device which engages a spool of the second belt retractor when both belt webs are wound up on their respective retractors to prevent engagement of the two-point belt system if the three-point belt system is not engaged.

Abstract: A safety belt for use in an automobile has a retractor reel incorporating a spindle onto which the belt is wound. The spindle can be locked, to prevent rotation of the spindle, in response to predetermined conditions, such as rapid deceleration of the automobile. The retractor reel is mounted on the chassis so that the reel can move relative to the chassis if a large force is applied thereto, by the safety belt, in excess of a predetermined limit. A clamp is also provided, which can clamp the safety belt leaving the reel, the clamp operating in response to movement of the reel as a consequence of the large force. A force limiter is provided to relieve any force exerted by the safety belt in excess of a predetermined limit.
