KNEE AIRBAG FOR VEHICLE
First Claim
1. A knee airbag device for a vehicle comprising:
- a knee airbag that, due to gas being supplied, inflates and is expanded toward a vehicle rear side; and
a glove box door that is provided so as to be able to open and close a glove box, and in which the knee airbag is accommodated in a folded-up state, and further, at which a rigidity of a lower portion that opposes knees of a passenger of a small body build is set to be lower than a rigidity of an upper portion that opposes knees of a passenger of a large body build.

Abstract
A knee airbag is provided to the lower part of a glove box door, and an airbag door provided to the glove box door opens in both upward and downward directions when the knee airbag expands. As the knee airbag expands, the rigidity of the lower part of the glove box door decreases, and this causes a relatively small reaction force, which corresponds to a relatively small load generated when the knees of an occupant having a relatively small body build make contact with the lower part, to be generated on the lower part of the glove box door. On the other hand, because the knee airbag is not provided to the upper part of the glove box door, the upper part can generate a relatively large reaction force which corresponds to a relatively large load generated when the knees of an occupant having a relatively large body build make contact with the upper part via the knee airbag.
