Leg airbag apparatus and automobile
First Claim
1. A leg airbag apparatus comprising:
- an airbag that deploys in an area including a position in front of legs of an occupant of an automobile;
an instrument panel holding a retainer that stores the airbag in a folded state therein; and
an inflator that inflates the airbag,wherein the airbag includes a body part that inflates in front of the occupant, and a projecting part that projects outward in a vehicle body width direction from the body part,wherein, in an inflated state of the airbag,a length from an occupant center line of the airbag to an outer end of the projecting part in the vehicle body width direction is longer than a length from the occupant center line of the airbag to an inner end of the airbag at a side opposite to the projecting part in the vehicle body width direction, andthe projecting part protrudes from the body part to a vehicle body rear side,an occupant side panel of the airbag is partly folded inwardly to connect together to define a tuck portion, the tuck portion being provided near a boundary portion between the projecting part and the body part in the occupant side panel of the airbag such that the projecting part protrudes to the vehicle body rear side, andthe airbag inflates and deploys upward along the instrument panel from a lower part of the instrument panel.

Abstract
A leg airbag apparatus can restrain occupant legs from moving obliquely forward in an offset collision and in the leg airbag apparatus, an airbag inflates and deploys early without using a high-output inflator, and an automobile includes the leg airbag apparatus. An airbag includes a body part that inflates in front of an occupant, and a projecting part that projects only outward in a vehicle body width direction from at least an upper portion of the body part. In an inflated state of the airbag, a length from an occupant center line of the airbag to an outer end of the projecting part in the vehicle body width direction is longer than a length to an inner end in the vehicle body width direction. The projecting part is protruded to the vehicle body rear side by being pulled by an outer tether.
