Abstract

A side impact head restraint with inflatable deployment in which an inflatable member having a movable mounting point is used to deploy a fabric panel during a side impact collision for head protection. The inflatable member, made of coated fabric, is pressurized by a gas generator. The inflatable member is connected to fabric panel and is used to bring a fabric panel into position in the window area of a side door of the vehicle. The fabric panel is secured at three points, two fixed points located on the upper side rail and a third movable point on a track located on the "B" pillar. The inflatable member pushes the movable mounting point down the track from a position near the upper side rail down to a position immediately below the centerline of the side glass. The movable point locks into position at the end of the travel, when fully deployed. The fabric panel can then be loaded by the head wherein fabric elongation absorbs head impact energy.
