20100156078 | AIRBAG, AIRBAG DEVICE, AND VEHICLE - An airbag comprises a right half airbag to be inflated on a front right side of an occupant, a left half airbag to be inflated on a front left side of the occupant, and a base-end chamber that communicates with base-end sides of the right half airbag and the left half airbag. A vertically extended concave portion exists on a surface of the inflated airbag that faces the occupant. The upper parts of the right half airbag and the left half airbag, and the lower parts of the right half airbag and the left half airbag are stitched together by seams, and the intermediate parts of the right half airbag and the left half airbag are stitched together by a seam. The seam is provided at the deepest location. The concave portion is shallow in the upper part and lower part thereof. | 06-24-2010 |
20100201107 | AIRBAG, AIRBAG DEVICE AND AIRBAG EXHAUSTING METHOD - [Object] To provide an airbag, an airbag apparatus, and an air-discharging method of the airbag which are able to reduce the pressure loss during inflation and deployment of the airbag, or is able to demonstrate the impact absorbing capability of the airbag apparatus efficiently depending on the physical structure of an occupant. | 08-12-2010 |
20110042922 | FOLDING METHOD OF AIRBAG - A folding method of an airbag having a left airbag portion and a right airbag portion is disclosed. In one form, the method includes the steps of: a primary folding step for forming a primary folded body in which said airbag is flattened along a top-bottom direction and along a right-left direction by folding said airbag in a manner that decreases a thickness of said left airbag portion and said right airbag portion along a front-back direction and at least partially separates a left surface of said left airbag portion and a right surface of said right airbag portion along the right-left direction; and a secondary folding step for forming a final folded body by folding said primary folded body in a manner that decreases its width along the top-bottom direction and along the right-left direction. | 02-24-2011 |
20110068564 | AIRBAG AND AIRBAG DEVICE - To provide an airbag and an airbag device that is excellent in an impact absorbing force and can efficiently inflate and deploy the airbag. An airbag | 03-24-2011 |
20120068446 | AIRBAG APPARATUS AND TETHER SEWING METHOD - There is provided an airbag that is folded up in a normal state and is inflated and deployed in an emergency state. The airbag includes: a base fabric; a tether sewn to the base fabric and configured to restrict a shape of the airbag when the airbag is inflated and deployed. The base fabric has a first pin hole therethrough in a contact region where the base fabric and the tether contacts each other, and the tether has a second pin hole therethrough in the contact region, wherein a position of the second pin hole corresponds to a position of the first pin hole. The tether has a folded back portion sewn to the tether and covering the first and second pin holes. The respective first and second pin holes are configured to receive a positioning pin for fixing the base fabric and tether to each other. | 03-22-2012 |
20120126515 | PASSENGER-SIDE AIRBAG FOLDED BODY AND PASSENGER-SIDE AIRBAG APPARATUS - There is provided a passenger-side airbag folded body in which an inflator opening is provided at a base end of an airbag and a vent hole is provided at each of right and left side surfaces of the airbag. Right and left end parts of the airbag are folded along vertical fold lines, thereby providing a vertically long primary folded body. The primary folded body is folded along lateral fold lines, thereby providing the passenger-side airbag folded body serving as a final folded body, and the vent holes are exposed at right and left end faces of the final folded body. | 05-24-2012 |
20130154244 | PASSENGER SEAT AIR BAG, PASSENGER SEAT AIR BAG APPARATUS AND VEHICLE - When an air bag body beings to expand due to gas flowing from an inflator into the air bag body, a left side folded piece and a right side folded piece which have been folded into concertinas expand quickly to thrust laterally to the left and right. Vent holes are located to be exposed in upper faces of the folded pieces. Accordingly, the gas can flow out from the interiors of the folded pieces through the vent holes as soon as the folded pieces begin to expand. | 06-20-2013 |

20140353952 | PASSENGER AIRBAG, PASSENGER AIRBAG DEVICE, AND VEHICLE - A passenger airbag and a passenger airbag device in which when the passenger airbag starts to inflate with an interfering object close to the IP, gas in the airbag is caused to quickly flow out through vent holes to reduce the impact on the interfering object, and a vehicle equipped with this passenger airbag device. In case of front collision of the vehicle, an inflator is activated to generate gas, and the gas flows through a diffuser into an airbag main body. The diffuser inflates, and the diffuser and the airbag main body thereby start to deploy above the IP. In this early stage of deployment, the diffuser is quickly almost fully inflated, and gas discharge openings are located above the IP. The diffuser is provided with a depression, and the depression faces the interfering object M. | 12-04-2014 |
