The object is to provide a leg protection device for vehicle occupants which has an airbag of which thickness when inflated is small so that the airbag can be rapidly inflated even with a gas generator having small generating capacity and which can sufficiently receive and stop occupant's legs. As a vehicle equipped with a leg protection device (1) comes into a frontal collision, a gas generator (5) is actuated to spout out gas through gas ports (5b) so as to initiate the inflation of an airbag (90A). Gas from the gas generator (5) first flows into a first chamber (116) so that the first chamber (116) starts to inflate. Subsequently, the gas in the first chamber (116) flows through the inlets (22a) to inflate the second chamber (18). According to the initiation of inflation of the airbag (90A), an interior panel (2) is pressed by the airbag (90A) so as to be torn along tear lines (6), forming flaps (25). The airbag (90A) is deployed into a vehicle cabin to extend along the front surface of the interior panel (2). The inside of the airbag is divided into said first chamber and the second chamber by a partition panel (96) and the partition panel is provided with at least one vent hole (112) for allowing the communication of gas. |
