Method and apparatus for inflating an inflatable vehicle occupant restraint.

摘要

A method of inflating an inflatable vehicle occupant restraint (12) comprises the step of directing inflation fluid to flow into the restraint (12) to inflate the restraint (12) in a vehicle (11) between a vehicle seat (16) and a side portion of the vehicle (11), such as a vehicle door (18). The inflation fluid increases the internal fluid pressure of the restraint (12) toward a maximum internal fluid pressure as the inflation fluid flows into the restraint (12). The method further comprises the step of constraining the restraint (12) to resist inflating the restraint (12) during at least a portion of the step of directing inflation fluid into the restraint (12). The step of constraining the restraint (12) causes the restraint (12) to reach a constrained volume at which the internal fluid pressure is approximately 70-100% of the maximum internal fluid pressure at approximately 6-8 milliseconds after the inflation fluid begins to flow into the restraint (12).
