The two covering sections each form an airbag layer which are connected to each other for forming the airbag covering and which upon inflation of the airbag move away from each other. The airbag layers moving away from each other introduce a force into the connecting means so that the connections between the two covering sections is released. | 02-23-2012 |
20120068444 | AIRBAG DEVICE - The present invention provides an airbag device that is capable of restraining a rectification cloth that switches a vent hole to an opened or closed state so as not to be twisted, and that is capable of switching the vent hole from an opened state to a closed state, and further, switching to the opened state. At an initial stage at which an airbag main body inflates and expands, the vent hole 8 is arranged between the leg portions 5, and when the airbag main body is in a predetermined internal pressure state, the vent hole is closed by means of the band-shaped portion 4. If an occupant or the like comes into contact with the airbag main body, a tense state of each of the leg portions is released, the rectification cloth is established in a slackened state, and the vent hole 8 is established in an opened state. | 03-22-2012 |
20120074677 | AIRBAG, AIRBAG DEVICE, AND METHOD FOR SEWING LID MEMBER OF AIRBAG - Provided are an airbag, an airbag device, and a method for sewing a lid member of an airbag that can make it easier to maintain the internal pressure until inflation and deployment of the airbag are completed and to quickly release gas after an occupant contacts the airbag. An airbag includes a vent hole for releasing gas supplied in the airbag, a lid member for making the vent hole openable and closable, and a tether for applying tension to the lid member. A seam formed by sewing the lid member to the airbag is disposed in a sewing region defined by a straight line shape spaced a predetermined distance from the vent hole, and a curved shape (most curved shape) formed by bringing both ends of the straight line shape close to a center line of the vent hole parallel to the straight line shape. The curvature of the seam can be regulated in view of the lap width between the lid member and the outer edge of the vent hole. | 03-29-2012 |
20120153603 | AIRBAG VENT ASSEMBLY - An airbag cushion of flexible sheet material has a vent opening therein with a vent cover of flexible sheet material stitched to an interior surface of the airbag cushion aligned with the vent opening in the airbag cushion to form a pocket. The vent cover has a vent opening therein that allows airbag inflation gas to escape from the airbag cushion via the vent opening in the airbag cushion. A vent flap of flexible sheet material is disposed at least partially within the pocket and inboard of the vent openings in the airbag cushion and vent cover. The vent flap is fixed to at least one tether that extends outboard from the vent flap through an opening in the vent cover to a tether end that is permanently attached to the airbag cushion outboard of the vent cover. A tether extends inboard from vent flap to a tether end that is fixed in a releasable manner to a tether end securing device fixed to a module housing. The tether end securing device reacts to a signal to release the end of the tether when a sensor senses a predetermined parameter during deployment of the airbag. The vent flap is pulled in an outboard direction by a tether to become interposed between the vent openings in the airbag cushion and the vent cover and prevent the escape of inflation gas through the vent openings in the airbag cushion and the vent cover. | 06-21-2012 |
