Leg protection device for vehicle occupants

摘要

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. The airbag comprises a front panel (11) arranged to face a vehicle occupant and a rear panel (12) arranged to face a vehicle member. The inside of the airbag is divided into a first chamber (21) and second chambers (22) by a linear joint portion connecting the front panel (11) and the rear panel (12). The second chambers are provided at their inlets with a partition (15) extending in a direction perpendicular to the longitudinal direction of the second chambers (22).
