HEADREST AIRBAG FOR VEHICLE

A headrest airbag for a vehicle is provided. The headrest airbag has an airbag cushion that is deployed forward from a headrest to surround an occupant's head which minimizes the occupant's head movement by holding the occupant's head in advance thus protecting the occupant's head against impact Further, a rear cushion is deployed backward from the headrest, whereby both a front seat occupant and a rear seat occupant are safely protected from impact by preventing an injury caused when the rear seat occupant hits the front seat
