Knee airbag with clamshell housing

Abstract

A knee airbag module (200) has an airbag (201), an inflator (206) and a housing (202). The knee airbag module (200) is a self-contained assembly for mounting to a vehicle frame part (108) under the instrument panel (106). The housing (202) contains the airbag (201) and inflator (206) within a hollow interior of the housing formed by a first housing part (300) and a second housing part (302). The first and second housing parts are joined together. The housing (202) includes a deployable door cover (220) formed in the second part that articulates about a hinge (222) as the airbag (201) is inflated. The airbag (201), when inflated, extends upward relative to the lower portion of the instrument panel (106) between the instrument panel (106) and an occupant's knees (120). The door cover (220) is partially separated from the second housing part (302) by a tear seam (320). The hinge (222) is near a portion of the tear seam (320).
