Abstract

An apparatus to position a 3-point restraining device to and out of immediate proximity to a person seated in a car. Its operation may be manual, mechanically assisted, automatic or fully passive. A length of webbing or cable has one end anchored to vehicle floor back and inboard of its seated user, the other end anchored back and inboard of his head to a "Central-Post". The door panel or body side closest to the seat supports a diagonally disposed track channel over which slides a belt carrier supporting the mid-portion of the device and dividing it into lap-belt and shoulder-belt portions. When the vehicle door is opened, it causes the belt carrier to slide forward and upward, removing the device away from its user; when it is closed, the device is repositioned and locked over its user'"'"'s lap and chest. The apparatus is usable with most seats of most motor vehicles and accepts various auxiliary protective devices.
