Two stage high retention fastener

摘要

A fastener system for use with an air bag includes a fastener (10) having a rounded base (16) having a flat portion, and first and second arms (18) oriented transverse to the flat portion. A first set of engagement devices (22,24) is connected proximate the rounded base (16). A second set of engagement devices (46,48) is connected spatially separated from both the first set of engagement devices (22,24) and the rounded base (16). A vehicle component (99) has a dog-house (98). The rounded base (16) is received and engaged in a dog-house cavity (112) connecting the fastener (10) and vehicle component (99). The vehicle component (99) displaces upon air bag deployment from a first engagement position having the first engagement device set (22,24) engaged with a vehicle body panel (126), to a second engagement position having the second engagement device (46,48) set engaged with the vehicle body panel (126). A second fastener sliding part (14) allows telescopic extension of the vehicle component (99).
