Abstract
An air bag safety system with an emergency venting assembly. The air bag system includes an air bag cushion, an inflator assembly and a cover that is movably attached to the inflator assembly. The inflator assembly includes an inflator and a housing with a side wall assembly configured to cooperate with the cover. The side wall assembly comprises an inner wall having a hole formed therein and an outer wall. The cover is movably attached to the inflator assembly. The cover has a side wall with an emergency relief vent formed therein. The cover further has a first position and a second position such that when the cover is in the first position the emergency relief vent on the side wall of the cover is substantially aligned with the hole in the inner wall of the housing so as to allow the inflation fluid to exit the inflator assembly. When the cover moves to the second position the cover has been laterally displaced in relation to the inflator assembly such that the emergency relief vents in the side wall of the cover and the hole in the inner wall of the housing are no longer aligned thereby forcing the inflation fluid into the air bag. The displacement of said cover from the first p…
