Air bag cushion with fabric diffuser

摘要

A device is provided for controlling the forward momentum of the front surface of an automotive air bag cushion during deployment thereof. A diffuser is installed inside the air bag cushion near the gets inlet and substantially perpendicular to the flow of gas from the inflator. The diffuser results in reduced forward momentum of the front part of the air bag cushion thus permitting the lower portion of the air bag cushion to deploy toward the occupant of the vehicle so that initial contact of the air bag is made with the lower torso of an occupant. The cushion is thereby moved into a lower position in front of the occupant's torso more quickly than an air bag cushion equipped without a diffuser. The diffuser of this invention also provides secondary filtration of particulate matter from the gas stream.
