Seatbelt system

摘要

A seatbelt system which includes an anchor plate which anchors one under the passenger restraining belt and which is fastened to a runner piece which moves along a guide rail fastened to a motor vehicle body. When the anchor plate receives a driving force, the anchor plate moves along the guide rail so that the belt is automatically fastened about the passenger. The seatbelt system is further arranged and configured such that a belt anchoring portion of the anchor plate and a portion of the runner piece that is directly supported by the guide rail are both provided on a straight line which coincides with the line of action of belt tension during a vehicular emergency whereby belt tension is securely supported by the guide rail.
