Air bag unit and assembling method and apparatus therefor.

摘要

Air bag apparatus comprises at least an air bag (114) for protecting a driver of a vehicle upon collision of the vehicle, a base plate (108) for mounting thereon a gas inflator for inflating the air bag, and a pad cover (107) secured to the base plate (108) for accommodating the air bag and the gas inflator therein. Part of the base plate (108) is deformed into a predetermined shape to secure the pad cover (107) to the base plate. Preferably, part of the base plate (108) is bent to form a side inner face portion and is further folded back to form a side outer face portion, and a terminal portion of the pad cover (107) is held between and secured by the side outer face portion and the side inner face portion of the base plate (108). Methods and apparatus (101,102,104) for assembly of the air bag system are also disclosed.
