Abstract
An airbag for knee protection includes at the center in a left and right direction of the upper edge an accommodation recess that recesses downward for accommodating an underside of the column cover. An outer wall of the upper region of the airbag is comprised of a panel material that is doubled on a turn crease that extends straightly through the panel in a left and right direction and forms the upper edge of the airbag. The airbag further includes beneath the turn crease and in the vicinity of the center in a left and right direction of the upper panel and above the thickness regulating tether a connecting member that approximates the driver-side wall and column cover side wall of the airbag to each other so as to provide the accommodation recess. The connecting member is arranged to form a communication passage between the connecting member and the turn crease that allows inflation gas to flow through in a left and right direction.
