US Patent 8936270 Disposition structure for curtain airbag system

A disposition structure for a curtain airbag system in which the airbag, when deployed, deforms an end of a roof trim toward the inside of a passenger compartment. An airbag guide support retains an airbag guide in a normal position in which an end of the airbag guide is kept away from an upper end of a pillar trim and a top surface of the airbag guide faces the under surface of the folded airbag. When the airbag is inflated and deployed, the airbag guide receives a downward pressing force from the inflating airbag on the top surface of the airbag guide and moves to a position of action in which the airbag guide covers the upper end of the pillar trim from above.
