Abstract
A method of inflating an airbag includes expanding a collapsed or folded frame that supports and expands the airbag. The expansion of the airbag creates a lower pressure in the interior of the airbag as compared to the exterior, which allows air to be drawn into the airbag due to the lower pressure to fill the airbag. The frame can be made from inflatable ribs, or the frame can be made from interconnecting rigid members. The inflatable ribs can be inflated using a compressed gas canister, while the frame made from rigid members can be expanded using a spring. Filling a frame made from inflatable ribs, as opposed to the airbag itself allows for a smaller compressed gas canister.
