Patent attributes
A seat mounted side impact airbag module for protecting an occupant of a vehicle has an airbag with a first inflation chamber for engaging the pelvic region of the vehicle occupant and a second inflation chamber for engaging the thoracic region of the vehicle occupant. The inflation chambers are separated by a chamber separator. An inflator provides inflation gas to fill the airbag housed in a tubular housing manifold having a first aperture and a second aperture. The housing manifold is shaped to retain the inflator and create two discrete flows of inflation gas. A first flow of inflation gas goes into the first inflation chamber via the first aperture and a second flow of inflation gas goes into the second inflation chamber via the second aperture. The chamber separator is tightly sealed around the housing manifold to prevent the first flow and second flow to pass into the other inflation chamber. The chamber separator may be rubber coated with the housing manifold having a recess adapted to accept and hold the chamber separator sealed in a gas tight manner around the exterior of the housing manifold.
