The sections are defined by a hinge portion extending generally straight in the fore-aft direction of the vehicle and a plurality of lateral thin portions extending from the hinge portion generally in a lateral direction of the vehicle. When the airbag inflates, by means of inflation force of the airbag, the lateral thin portions rupture and the individual sections rotate about the hinge portion and open.
1. A side door for a vehicle comprising:
a folded airbag which inflates upward in response to a side collision of the vehicle; and
a cover member disposed above the airbag and covering the airbag, wherein
