Abstract
Side airbags to provide protection to vehicle occupants are provided. The side airbags include an outer skin forming an inflatable chamber having an upper thorax portion and a lower pelvic portion for contact with the thorax region and the pelvic region, respectively, of the associated vehicle occupant. The side airbag includes a loop diffuser for placement about an inflator disposed within the inflatable chamber. The loop diffuser has opposed first and second open ends to permit communication of inflation gas to the upper thorax portion and to the lower pelvic portion, respectively, of the inflatable chamber. The loop diffuser permits significantly greater flow of inflation gas to the lower pelvic portion as compare to flow of inflation gas to the upper thorax portion of the inflatable chamber. The first open end can be significantly smaller in cross section as compared to the second open end.
