Abstract:
An airbag cover adapted to be jointed with an airbag housing for covering an airbag housed in the housing. The airbag cover includes a door. In a circumference of the door, there are a hinge region which holds the door as opened, and a tearable region configured to break when pushed by the airbag. The tearable region includes a bridged tear region which includes perforations formed through the airbag cover and bridging regions disposed between the perforations, and is configured to break when the bridging regions break, and a thinned tear region which includes a continuous thinned region and is configured to break when the thinned region breaks. The bridged tear region is disposed at a leading end of the door as opened, distant from the hinge. The thinned tear region is disposed between both ends of the hinge region and both ends of the bridged tear region.
