Abstract: Disclosed is a vehicle airbag. The vehicle airbag includes a deployment restricting member linked with an upper portion of a rear surface part of an outer portion of the vehicle airbag, prepared in a strip shape, and having one end statically fixed with a collar of the vehicle airbag in adjacent to the collar of the vehicle airbag and an opposite end coupled with the upper portion of the rear surface part of the outer portion of the vehicle airbag, thereby delaying the rear surface part of the vehicle airbag. A tear part is provided at the central portion of the deployment restricting member so that the tear part is torn under a predetermined pressure. In initial deployment of the vehicle airbag, the upper portion of the rear surface part of the airbag is confined in a folded state, so that the lower portion of the airbag is first inflated. The airbag is prevented from being suddenly inflated, thereby preventing the chest, the neck, or the head of the occupant from being injured.
