Abstract
The present invention discloses a multiple-chamber airbag structure where the airbag design has at least a stiff lower section to reduce the chest velocity and a soft upper section to meet the HIC requirements. Although stowed and deployed as a unitary airbag, the present invention includes separate chambers, which allows for independent gas inflation and stiffness control with venting.
