Abstract
Abstract The seat assembly 10 with an inflatable air bag for protecting the occupant of the seat during a collision. More specifically, the air bag assembly, generally shown at 22, is, at least in part, formed integrally with one or both, of the seat frame members 12 and 14. Each of the load bearing frame members 12 and 14 has an integral section 24 thereof extending longitudinally along a portion of the length of thereof. In other words, the integral section 24 is shorter than the entire length of the associated frame member 12 or 14 and the integral section 24 defines an air bag storage pocket or recess 26 and an inflator housing 28. The integral section 24 includes a common wall 30 separating the bag storage pocket 26 from the inflator housing 28. The common wall 30 includes air holes 32 extending therethrough to convey expanding gas from the inflator housing 28 to the pocket 26 for inflating a bag. A rectangular frame 52 seals the mouth of the bag 50 about the periphery of the recess 26 in which the bag 50 is stored. A gas generating cartridge 54 is disposed in the inflator housing 28 to inflate the bag 50.
