Abstract

A seat belt system includes a control arm with one end pivoted to an upper sash of a door and with the other end portion mounted to a roof side of a vehicle body for slidable movement. A seat belt extends from an anchor mounted to the roof side to a retractor mounted to the roof of the vehicle body adjacent the inboard side of a seat. A portion of the seat belt passes through the other end portion of the control arm. A spring is mounted so that when the door is closed, the other end portion of the control arm is urged to displace rearwardly till the control arm extends along the roof side to allow the seat belt to fasten around a passenger on the seat. As the door is opened, opening movement of the door will pull the one end of the control arm outwardly of the vehicle body, thus displacing the other end portion forwardly to extend the seat belt forwardly of the passenger for easy ingress or egress.
