ABSTRACT:
A flow control device for use with inflatable confinements or "air bags" of vehicle occupant safety restraint systems is produced by incorporating in the wall of the confinement a fluid permeable portion which has a filamentous surface on one side in which flexible, filamentary projections align themselves in parallel relation as fluid permeates the portion and flows into the bag relatively unrestrictedly, and collapse against the surface as fluid permeates the portion and flows out of the bag relatively more restrictedly to provide rebound protection for the vehicle occupant.
