ABSTRACT:
An airbag system for motor vehicles and the like includes an inflatable airbag contained in a housing having a protective cover normally closing a panel opening aligned with an open end of the airbag housing. The cover is bodily movable away from the opening during deployment of the airbag and a flexible tether is interconnected between the cover and the panel or the housing for limiting the travel of the cover away from the panel opening during deployment. The cover includes an integral outer skin and inner skin folded over and spaced therefrom having slots to permit passage of tethers into a space formed between the skins and eventually filled with foam. An anchor in the form of an elongated element is placed between the skins and the tether and is secured to the anchor for spreading the load exerted by the tether over a wide area of the cover to prevent fracturing or breakage thereof. After the anchor and tether are in place, the inner and outer skins are secured together along an edge in a heat staking operation.
