Abstract
A leg protection device for protecting legs of a vehicle occupant from colliding against a vehicle member in front of the vehicle occupant includes an airbag installed inside the vehicle member and a gas generator for generating gas to inflate the airbag. The airbag has a first chamber having a first gas inlet and a second chamber having a second gas inlet. The airbag expands along the vehicle member when the airbag is inflated. The first chamber and the second chamber are connected so that the gas generated from the gas generator at first passes through the first chamber, then flows into the second chamber.
