Abstract: A curtain airbag in a stored state is provided to extend in a vehicle longitudinal direction at an upper position of a border of a pillar trim and a top ceiling. A guide portion is provided at an upper portion of the pillar trim so as to guide the curtain airbag which is being inflated toward a vehicle compartment. The curtain airbag includes a patch portion as an inflation suppression portion at a position which overlaps with the guide portion when viewed from the inside of the vehicle compartment. The patch portion as the inflation suppression portion is configured to suppress inflation of part of the curtain airbag where the patch portion is provided.

Abstract: A cell of a curtain airbag is configured such that its upper portion is closed in an inflated state of the curtain airbag, whereas its lower portion is open and connected to a gas flowing passage from an inflator. Accordingly, a passenger protection device of a vehicle which can properly prevent an interior material from being broken and scattered can be provided.

Abstract: A curtain airbag device for a vehicle has a curtain airbag main body 17 that is disposed along a longitudinal direction of a vehicle body while covered with an A pillar trim 41 and roof trim 42, and folded in an A pillar 7 and a roof side rail part 30 of the vehicle body so as to be able to deploy downward within a cabin. The curtain airbag main body 17 is provided with a twisted part 17b that is twisted such that an initial deployment force, generated upon inflation and deployment of the curtain airbag main body 17 located in a vicinity of the A pillar trim 41, is acted in a separation direction in which the A pillar trim 41 is parted away from the A pillar part 7, to push open the A pillar trim 41 toward an inside of the cabin. At least an upper surface of the twisted part 17b is regulated by a supporting bracket 21 and disposed in the vehicle body.

Abstract: A side airbag unit disposed in a side support of a seat capable of absorbing collision energy sufficiently during a side collision of a vehicle is described. In one example, the airbag unit comprises: a low expansion member disposed inside of a front skin of the seat, wherein one end of the low expansion member is attached to the inside of the front skin in the vicinity of a fragile part of the seat and the other end of the low expansion member is attached to the seatback frame through a slit. The low expansion member inhibits the front skin from expanding due to the inflation of the airbag, and a cushion pad located outside of the slit in the vehicle width direction and inside of the fragile part in the vehicle width direction is moved outward and frontward by the inflation of the airbag in a vehicle collision.

Abstract: A middle pillar trim and a rear pillar trim positioned to the front and rear of a side window glass are each harder than a roof trim. A curtain air bag fixed to a rear pillar is deployed in a vehicle cabin while a predetermined end edge of the front of the rear pillar trim in the widthwise direction of a vehicle is deformed toward the front. The separation distance of the curtain air bag in a stored state from the side window glass in the widthwise direction of the vehicle is L1 (L2) in the portion of the curtain air bag along the rear edge of the side window glass, and L4 in the portion of the curtain air bag at the upper edge of the side window glass near the middle pillar trim, and the separation distance L1(L2) is smaller than the separation distance L4.

Abstract: A structure of a rear portion of a vehicle furnished with a curtain airbag apparatus includes a rear pillar, a soft roof trim, a rear pillar trim harder than the roof trim, and a cover constituting part of the rear pillar trim and covering a specific area of a front face portion of the rear pillar trim. The curtain airbag apparatus includes a curtain airbag and an inflator for inflating and deploying the curtain airbag into the vehicle interior along side window glass. The cover of the rear pillar trim can easily be displaced frontward along an airbag deployment joint. When inflated, the curtain airbag fixed to a vehicle body along an upper edge and a rear edge of the side window glass in a retracted position deploys into the vehicle interior upon separating and displacing the cover of the rear pillar trim frontward from the other part thereof.

Abstract: A vehicle rear structure with a curtain air bag device is provided which is capable of, when a predetermined condition is satisfied, effectively restraining a front upper end of a rear pillar trim from breaking and scattering, and spreading a curtain member properly.

Abstract: A middle pillar trim PT3 and a rear pillar trim PT4 positioned to the front and rear of a side window glass G3 are each harder than a roof trim RT. A curtain air bag KB fixed to a rear pillar P4 is deployed in a vehicle cabin while a predetermined end edge 26a of the front of the rear pillar trim PT4 in the widthwise direction of a vehicle is deformed toward the front. The separation distance of the curtain air bag KB in a stored state from the side window glass G3 in the widthwise direction of the vehicle is L1 (L2) in the portion of the curtain air bag KB along the rear edge of the side window glass G3, and L4 in the portion of the curtain air bag KB at the upper edge of the side window glass G3 near the middle pillar trim PT3, and L1 (L2)<L4 is satisfied.
