An airbag module (10) for a motor vehicle comprising a housing (12); a door (14) having a pivot axis (22) and a tear line (20), and normally closing the housing; an inflatable airbag cushion (16) positioned in the housing; and an inflator (18) for inflating the airbag cushion; wherein the pivot axis extends around at least a portion of the outer circumference of the door; wherein the door comprises at least three portions (26) which are defined by the tear line; and wherein the tear line comprises at least three lines (32) each of which extend radially outwards from substantially the centre of the door. Reduces the risk of the door encountering an obstruction on actuation of the airbag module.
