Side-impact airbag module assembly incorporating combination airbag inflator and module housing
First Claim
1. A side-impact airbag module assembly comprising:
- a combination side-impact airbag inflator and module housing having an internal gas generant chamber and comprising a unitary one-piece hollow elongated longitudinal body having an outer surface, an inner surface, opposing first and second open ends, a plurality of gas exhaust ports extending from the inner surface to the outer surface, and two airbag receiving channels parallel with the longitudinal body and located on the outer surface on opposite sides of the plurality of gas exhaust ports, each airbag receiving channel having a slot running along the channel;
a first endplug located within and sealing the first open end and a second endplug located within and sealing the second open end, the second endplug having an access opening;
gas generant located within the gas generant chamber;
an ignitor connectable to a remote collision sensor and located within the access opening for igniting the gas generant;
an inflatable airbag cushion having an open mouth partly formed by two opposing mouth sides, each of said two opposing mouth sides forming an airbag tube, an airbag retaining rod located within each airbag tube, and said airbag retaining rods being wider than the slots in the airbag receiving channels, each airbag tube and its retaining rod being located within one of the airbag receiving channels so that the open mouth of the airbag is located above the plurality of gas exhaust ports;
a first endplate secured over both the first open end of the longitudinal body and the first endplug and a second endplate secured over both the second open end and the second endplug, the second endplate having an aperture located adjacent the access opening in the second endplug, the first and second endplates secured to the opposing ends of the longitudinal body and closing ends of the airbag receiving channels to retain the retaining rods within the airbag receiving channels between the endplates, and each endplate having a mounting bracket extending therefrom, andsaid open mouth of the inflatable airbag cushion is additionally formed by two opposing mouth ends that are retained between the endplates and the opposing ends of the longitudinal body.

Abstract
A side impact airbag module assembly having a combination airbag inflator and module housing and an airbag cushion. The combination airbag inflator and module housing has an extruded unitary one-piece hollow elongated longitudinal body having an outer surface, an inner surface, a first open end, a second open end, and a plurality of gas exhaust ports extending from the inner surface to the outer surface. Two airbag receiving channels, each channel having a slot running along the channel, are respectively located on the outer surface of the longitudinal body, parallel with the body on opposite sides of the plurality of gas exhaust ports. A first endplug seals the first open end and a second endplug seals the second open end with the inner surface of the longitudinal body and the endplugs defining a gas generant chamber containing a gas generant. A first endplate is secured to the first open end of the longitudinal body and a second endplate is secured to the second open end, the endplates closing ends of the airbag receiving channels. Each endplate has a mounting bracket extending therefrom. The airbag cushion is folded and bundled in a tearable or breakable wrapper and has an open mouth partly formed by opposed mouth sides that are secured within the airbag receiving channels between the endplates. The endplates also retain opposed mouth ends of the airbag cushion.
