  • Patent number: 5431446
    Abstract: A seat belt presenter (10) for an active seat belt system (14) for restraining a vehicle occupant includes a guide (82) having surfaces (87) which surround opposite major side surfaces (41, 43) of belt webbing (40). A lift arm (74) has an end portion (78) to which the guide (82) is attached. The lift arm (74) is movable between a presented position in which the guide (82) supports a tongue assembly (48) adjacent to the vehicle occupant and a stored position in which the guide is disposed when the tongue assembly is engaged with a buckle (50). A spring (110) biases the lift arm (74) and the guide (82) to the presented position. A motor (130) when energized moves the lift arm (74) and the guide (82) to the stored position. The guide (82) is maintained at a constant attitude angle as the lift arm (74) moves between the presented and stored positions.
