Abstract: A fastening clip with a flexible tether for use with a vehicle includes a first fastener attached to a component such as a vehicle body, and a second fastener attached to a removable component such as a vehicle trim panel. The first and second fasteners may be connected by generally rigid arms joined by an integral hinge and by at least one flexible tether capable of elongating and contracting. The hinged arms and tether provide multiple means to prevent the trim section from freely detaching from the vehicle body and becoming a projectile following deployment of an air bag from behind the trim panel. In addition, the rigid arms cause the trim panel to move in a controlled arc. A further aspect of the invention provides a tether that is capable of stretching to allow unimpeded air bag deployment followed by contracting to pull the trim panel back towards its original position on the vehicle body.
