Abstract

The present disclosure relates to a leg protection device for an occupant protection system of a vehicle. The leg protection device includes an airbag module. The airbag module includes an airbag and a gas generator that inflates the airbag to a deployed state such that the airbag is disposed in the footwell and in front of a vehicle seat. The airbag includes a first chamber and a second chamber fluidically connected to the first chamber. The first chamber and the second chamber are deployed in the footwell to protect an occupant when the airbag is set in the deployed state. The first chamber is connected to the second chamber by a flexible connection region that diverts the airbag along the object in any spatial direction when the airbag encounters the object during deployment in the footwell.
