Abstract
Abstract A vehicle occupant protection device (14) has an inflated condition wherein the vehicle occupant protection device is located between a side structure (16) of the vehicle (12) and a vehicle occupant. When in the inflated condition, the vehicle occupant protection device (14) has a given length measured in the direction of vehicle travel. The length of the vehicle occupant protection device (14) increases as measured in the direction of vehicle travel as the vehicle occupant protection device deflates from the inflated condition to a deflated condition. A first spring connector (52) connects the vehicle occupant protection device (14) to the vehicle (12). The first spring connector (52) applies force to the vehicle occupant protection device (14) as it deflates and maintains tension in the deflating vehicle occupant protection device.
