Inflatable bladder

摘要

An inflatable restraint system includes an inflator for generating inflator gas and a bladder inflatable upon generation of gas by the inflator. The bladder includes a forward panel, a rearward panel, and a pair of opposing end panels extending between and interconnecting the forward and rearward panels. Preferably, the bladder is made of a metal material. Also preferably, the system includes an instrument panel having a lower portion and the bladder is positioned beneath the lower portion of the instrument panel to serve as a knee bolster when inflated for protection of the occupant.
