20120161425 | AIRBAG - In an airbag, an external wall composed of a flexible woven cloth is adhered and configured by extending a thick thread base cloth and a fine thread base cloth with threads of different thicknesses while performing heat pressing with a coating layer interposed between the thick thread base cloth and the fine thread base cloth. The coating layer is formed by applying a coating agent that forms the coating layer on the thick thread base cloth side in advance. | 06-28-2012 |
20130341892 | GAS GENERATOR AND AIRBAG APPARATUS - A gas generator includes an inflator and a retainer. The retainer includes a holding portion, which partially covers the inflator. The inflator has an attaching protrusion for determining the position relative to the retainer. The retainer includes an engagement base and a tongue piece. The tongue piece extends in an axial direction of the inflator and from a position separated from the engagement base in the circumferential direction of the holding portion. The engagement base and the tongue piece each have an engagement portion. The engagement portions face each other to form an engagement space therebetween, into which the attaching protrusion enters. The engagement space has an inlet the width of which is less than the size of the positioning protrusion. When the inflator causes the positioning protrusion to increase the width of the inlet, the tongue piece is elastically deformed about a basal end of the tongue piece. | 12-26-2013 |
20140008903 | AIRBAG APPARATUS - An airbag includes a high pressure expansion chamber, a low pressure expansion chamber, and a communication passage, which connects the high pressure expansion chamber and the low pressure expansion chamber to each other. A gas supply port, which supplies inflation gas into the airbag, is located inside the low pressure expansion chamber to discharge the inflation gas toward the inside of the communication passage. The communication passage extends from the edge of a communication port, which connects the high pressure expansion chamber and the low pressure expansion chamber, toward the inside of the high pressure expansion chamber. At deployment and inflation of the airbag, the communication passage is located between a seam formed at the outer periphery of the base fabric sheet of the airbag and the gas supply port. | 01-09-2014 |
20140208567 | METHOD FOR MANUFACTURING AIRBAG - An airbag is manufactured as follows. In a first joining step, peripheral portions of structural fabric portions that are located closer to the main body fabric portions at the installation are joined to the main body fabric portions in a spread state. In a second joining step, a part that is not overlaid onto the structural fabric portions is joined to the main body fabric portions, and a part that is overlaid onto the structural fabric portions is joined only to the structural portions. In a third joining step, peripheral portions of the structural fabric portions that are separated away from the main body fabric portions at the installation are joined to each other. | 07-31-2014 |
20140265277 | AIRBAG APPARATUS - An airbag apparatus has an airbag formed by sewing fabric portions together at peripheries thereof. A periphery sewn portion of the airbag has two terminals separated from each other. The terminals are formed by leaving sections of the peripheries of the fabric portions unsewn. A surrounding sewn portion is formed about each terminal of the periphery sewn portion. The airbag has a vent hole between the terminals. The opening of the vent hole is defined by vent hole defining sections, each of which is in one of the surrounding sewn portions. Position determining portions are provided in the margin of the airbag. Each surrounding sewn portion is formed in place with reference to the corresponding position determining portion. Each position determining portion is located father from the vent hole in the circumferential direction of the margin than the vent hole defining section of the corresponding surrounding sewn portion. | 09-18-2014 |
20150021884 | SIDE AIRBAG APPARATUS - An airbag is formed in a bag shape by joining margins of one pair of main body cloth portions. Inflation gas is supplied from an inflator to the airbag according to an impact given from the side of a vehicle seat. With this supply, the airbag deploys and inflates. A longitudinal partition portion is laid between the one pair of main body cloth portions. The longitudinal partition portion partitions an interior of the airbag into a front part and a rear part and has a communication hole. An inside one of the main body cloth portions constituting the airbag is attached to a car. The airbag is attached to a side frame inside the vehicle seat at a position between a rear end of the inside main body cloth portion and the longitudinal partition portion. | 01-22-2015 |
20150021887 | SIDE AIRBAG APPARATUS - An airbag main body is divided into a first inflation chamber, a second inflation chamber, and a third inflation chamber. The third inflation chamber is inflated beside the lumbar region of an occupant. The vertical partition has a communication hole that connects the first inflation chamber and the second inflation chamber to each other. The airbag main body has a gas passage, which extends in the up-down direction and surrounds at least the gas outlet of an inflator. The gas passage bridges the first inflation chamber and the third inflation chamber. The gas passage has an upper opening, which faces a part of the first inflation chamber that is inflated beside the shoulder region of the occupant. The gas passage also has a lower opening, which faces the third inflation chamber. | 01-22-2015 |
