PURPOSE: Structure of a door in a multi-stage airbag is provided to minimize a passengers injury by reducing pressure of the airbag. CONSTITUTION: A door(60) of a multi-stage airbag comprises a first door(62) opened primarily to protrude the airbag(40) outside a crush pad(10) of a front passengers seat when the airbag(40) is exploded with low pressure from an airbag module(20); and a second door(64) opened secondarily to protrude the airbag(40) outside the crush pad(10) when the airbag(40) is exploded with high pressure from the airbag module(20). Thereby, a passengers injury is minimized by reducing high pressure of the airbag.
