Abstract: A four-point seat belt system for restraining a vehicle occupant in a vehicle seat is disclosed. The system includes a four-point seat belt restraint system mounted on a vehicle seat that includes a first lap belt portion having a back side and a second lap belt portion having a back side. A portion of at least one of the back side of the first lap belt portion or the back side of the second lap belt portion has a contour which substantially corresponds to the contour of the lap of the seated vehicle occupant. The contour is defined by a convex surface. Each of the buckle portion and the tongue portion may include a button release.

Abstract: A four-point seat belt system for restraining a vehicle occupant in a vehicle seat is disclosed. Two shoulder belts are provided which are buckled together with a pair of lap belts. The convergence of the shoulder belts created at the buckles defines a V-shaped configuration which aids in occupant safety and comfort. Movably-adjustable retractors are provided to anchor the upper end of each shoulder belt to the vehicle seat. A movable headrest having a pair of laterally-adjustable belt loops is provided to further enhance occupant security and comfort.

Abstract: A four-point seat belt system for restraining a vehicle occupant in a vehicle seat. Two shoulder belts mounted on separate spool members are connected to a common retractor mechanism, which synchronizes web payout and retraction and also shares a load limiting function. The shoulder belts are connected to a lap belt, which is buckled centrally on the abdomen of the occupant. A load limiting system controls occupant motion and reduces force levels on the occupant's chest. A single load limiting method can be used to accommodate all occupants of the vehicle with specific force versus belt payout properties.

Abstract: A four-point seat belt restraint system having a lap belt movable between a comfort position wherein the portions of the belt extending over the outsides of the occupant's thighs are generally vertical, and a crash restraint position wherein the same portions extend at an angle downward and to the rear. Belt guides disposed adjacent opposite sides of the seat engage the lap belt as it extends from the anchor points toward the seat cushion. During normal vehicle operations, the belt guide is located in a comfort position that causes the portion of the lap belt passing over and around the outsides of the occupant's thighs to have a relatively vertical orientation. In the event of an actual or impending crash or other rapid vehicle deceleration, a restraints control module commands an actuation mechanism to move the belt guides rearward with respect to the comfort position, allowing the lap belt to extend in a substantially straight line to the rear-located anchor point.

Abstract: An occupant restraint system for a vehicle seat includes a three-point belt assembly comprising a shoulder belt and a lap belt releasably secured at an first buckle element and a supplemental shoulder belt having an upper end adjacent an upper first portion of the seat back and a lower end releasably secured to a second buckle element. The second buckle element is secured to the lap belt attachment in a position to restrain the second ends of the lap belt and supplemental shoulder belt in a configuration that is symmetric about the centerline of the seat with the configuration of the first ends of the lap belt and the shoulder belt where they are secured to the first buckle element. The load-carrying paths for the first ends of the lap belt and shoulder belt intersect one another at an intersection point that is symmetric with the intersection point where the load-carrying paths for the second ends of the lap belt and supplemental shoulder belt intersect one another about.
