A curtain airbag device of the present invention includes an airbag body including a bend-facilitating portion which is formed of a non-inflating portion of the airbag body in at least one chamber disposed at a lower end portion of the airbag body and which facilitates bending of the airbag body during inflation and deployment of the airbag body. In the curtain airbag device, the chamber including the bend-facilitating portion includes a passage for distributing the gas such that the gas comes around the bend-facilitating portion in one direction.

Curtain airbag device

A curtain air bag formed so that an auxiliary inflatable chamber adapted to reduce to as great an extent as possible a substantial decrease in a protective region of an air bag bodycan be formed. The air bag bodyis deployed into the interior of an automobileby introducing a high-pressure gas, which is ejected from an inflator at the time of the occurrence of collision of the automobilewith something, into the interior of the air bag body. An auxiliary inflatable chamberdefined with respect to a main inflatable chamberis obtained by sewing the air bag body by a substantially one sewing line using a multi-thread chain stitch method or the like. The auxiliary and main inflatable chambersare communicated with each other via a narrow orifice type gas flow restriction passage

Curtain air bag for vehicles

An airbag is disclosed wherein a lower deployment portion, right deployment portion, and left deployment portion are folded on the occupant side of a central deployment portion in an optional order. The upper deployment portion is folded to be located on the most occupant side and upper side of the folded deployment portions.

Airbag, airbag folding method, and airbag device

An air bag apparatus includes a folded air bag, an inflator arranged to discharge a high pressure gas into the air bag at a collision of the vehicle, and a container member receiving the air bag, covering a non-deployment side of the air bag, and retaining the inflator. The container member includes a rigid base plate supporting the inflator and the air bag, covering one part of the non-deployment side of the air bag, and supporting a reaction force of the air bag at a deployment of the air bag, and a flexible panel including a connecting portion connected with the base plate, covering the other part of the non-deployment side of the air bag, and being arranged to restrict inflation of the air bag on the non-deployment side at the deployment of the air bag.
