Abstract

The present invention relates to an inflatable air bag apparatus attached to a harness restraint system in a vehicle which inflates if an impact sensor detects an impact. The apparatus comprises an bladder attached to the harness's shoulder strap. The sides of the bladder wrap around the shoulder strap and are folded on top of the shoulder strap. When an impact is detected, the impact sensor transmits an electrical signal which ignites the gas generator, and inflates the bladder. In a preferred embodiment, the bladder member comprises three chambers, a central chamber and two side chambers. The chambers are formed by two vertical webs that divide the bladder into the central chamber and the side chamber. The webs are fabricated from permeable material, such that the side chambers inflate before the central chamber inflates, thus stabilizing the air bag apparatus.
