Abstract
In a knee protecting airbag device of the present invention, an airbag is folded and housed on the front side of the knees of a seated passenger. The airbag is protruded rearward of a vehicle from a protruding opening and expanded and inflated upward, when an inflating gas flows in. And, the airbag is arranged on the front side of the knees of the passenger between a member on the body side and the knees of the passenger thereby to protect the knees of the passenger. The protruding opening has a transverse width size set within a range of ⅛ to ⅔ of the transverse width size of the airbag having completed its expansion and inflation.
