US Patent 9982699 Energy absorption rotatable fastener

An energy absorbing rotatable fastener to attach curtain air bags to a vehicle body includes a metal clip with a rectangular central aperture and inward flanges on opposing sides of the aperture. A molded pin includes a manipulation portion and an energy absorption portion supported on the clip with a biasing element urging the pin outward. The pin and clip connect an air bag tab and body plate and the pin is rotatable in an arc of 45° to place the energy absorption portion in an energy absorbing position between the tab and body plate. The pin and clip each provide energy absorption on air bag deployment. In one form, the manipulation portion of the pin includes a drive cap that provides ninety degrees (90°) of lost motion.
