Abstract: Motorized shoulder and lap belts are moved to restraining positions by a drive belt along a track around a doorway of a vehicle. A catch in a slot in the drive belt engages the shoulder belt to move with the lap belt which is attached to the drive belt. An adjustable height stop in the track stops and disengages the shoulder belt in the shoulder belt restraining position from the catch while the lap belt continues to move and stops in the lap belt restraining position. A persons weight in a seat of the vehicle and closing the vehicle door, if the vehicle ignition is turned on, activates a switch which moves the shoulder and lap belts into their restraining positions. With the person seated, the shoulder and lap belts are retracted by turning the vehicle ignition off, or by activating a switch located in the vehicle door handle, door post, or elsewhere in the vehicle. Sleeves located near where the shoulder and lap belts enter retractors are disposed around ends of the shoulder and lap belts.

Abstract: Motorized bi-level safety belts having a lap belt and a shoulder belt with a base end of each anchored to a separate retractor at an inside portion of a vehicle seat. Moveable ends of the lap belt and shoulder belt are attachable to a moveable base that is separable into a shoulder level and a seat level. The moveable base travels in a rail from a body-release mode in a position at a front of a vehicle door to a body-restraint mode in which the moveable base is separable into a shoulder level and a seat level at the back of the door. The rail is attached to a frame of the door. Curved accurately shaped, rigid areas of the belts are provided to prevent contact of a lap belt and a shoulder belt with a body of an individual on a vehicle seat and to prevent contact of the safety belts with a steering wheel of a car in transit between body-release and body-restraint modes.
