Abstract:
A knee airbag device for a vehicle is provided that is capable of effectively protecting both knees of a seat occupant, regardless of position, shape or the like of an airbag door relative to the seat. In a passenger seat knee airbag device, a tear line of an airbag door retainer is broken and airbag doors are deployed upward and downward by deployment force of a knee airbag that receives a gas supply from an inflator. Thus, the knee airbag is deployed toward the knees of the occupant through an aperture portion formed in the airbag door retainer. A tear line of a form that is non-symmetrical between left and right is formed in a retaining sheet that is for retaining the knee airbag in a folded state. Thus, timings of deployment of the airbag doors by inflation pressure of the knee airbag are caused to differ between a left side portion and a right side portion.
