Abstract
The present invention comprises a new and improved method and apparatus for packing an inflatable air bag cushion into a housing of an air bag module assembly of an occupant restraint system for a motor vehicle. After securing an inlet chute of the air bag cushion in the open end of the housing and placing the air bag on a flat support with a larger portion of the back wall thereof overlaying a small portion of the back wall with the front wall in between in a folded condition, a central portion of the air bag is clamped by a large blade and subsequently a first edge portion is folded over the central portion and a second opposite edge portion is folded over the first edge portion so that opposite edge fold lines extend outwardly just inside opposite ends of the housing. A rolling clamp is attached transversely across the folded air bag and the air bag is rolled-up on an axis moved toward the housing. An inverted channel element is placed over the rolled-up air bag from above and moves the air bag to a position at the open end of the housing. An outer wall of the channel element which in any upwardly retracted position causes the rolled-up bag to be inserted into the housing and a …
