20110074136 | Airbag apparatus - An airbag apparatus is mounted on a vehicle as housed in a housing and includes an airbag inflatable with inflation gas for catching an object of protection. The airbag includes a sheet-shaped circumferential wall made from synthetic resin. The circumferential wall is plastically deformable in such a manner as to be elongated due to increase of internal pressure caused by being pressed by the object of protection when arresting the object of protection at full inflation. | 03-31-2011 |
20120025499 | AIRBAG APPARATUS - An inflation portion of an airbag, which is inflated by inflation gas, is partitioned into an upstream inflation portion and a downstream inflation portion via a partition member. When being tensioned in a planar manner, the partition member has a length in a longitudinal direction that is longer than a length in a transverse direction perpendicular to the longitudinal direction. A pressure regulating valve that is closed at an early stage of a supply period of the inflation gas to the inflation portion and is opened from the middle of the supply period includes a slit-like inner opening that is provided on the partition member and extends in the transverse direction and a pair of valve body portions that are provided around the inner opening and are selectively positioned close to and separated from each other. | 02-02-2012 |
20130076013 | SIDE AIRBAG APPARATUS - The airbag has a front portion, in which a front chamber is formed, a rear portion, in which a rear chamber is formed, and a partition, which partitions the front and rear chambers from each other. The partition has a communication passage for connecting the front and rear chambers to communicate to each other. A pressure regulating valve is located in the passage. At an early stage of a supply period during which an inflator supplies inflation gas to the airbag, the valve is closed to restrict flow of the inflation gas from the rear chamber to the front chamber via the passage. The valve is opened during the supply period to permit the inflation gas to flow therethrough. A front portion of the airbag is roll-folded, while a rear portion is accordion-folded. The airbag front portion and the airbag rear portion are located in front of the inflator. | 03-28-2013 |
20130200597 | SIDE AIRBAG APPARATUS - An airbag includes a check valve in a communication passage connecting a lumbar-region-protecting inflatable portion and a shoulder-protecting inflatable portion. The check valve restricts outflow of inflation gas from the lumbar-region-protecting inflatable portion to the shoulder-protecting inflatable portion. A pressure regulation valve, which has an internal opening and a pair of valve body elements, is provided in a partitioning member between the shoulder-protecting inflatable portion and a thorax-protecting inflatable portion. Before an occupant is restrained by the shoulder-protecting inflatable portion, the valve body elements are pressed and contact with each other by inflation gas in the shoulder-protecting inflatable portion, thereby restricting flow of inflation gas at the internal opening. When the occupant is restrained by the shoulder-protecting inflatable portion, the valve body elements are flexed and separated from each other by external force applied following the restraining, thereby permitting flow of inflation gas at the internal opening. | 08-08-2013 |

20140084571 | AIRBAG APPARATUS - Inside of an airbag is partitioned by a partitioning member into an upstream inflation portion, which is inflated by a supply of gas, and a downstream inflation portion, which is inflated by inflow of the gas from the upstream inflation portion. The partitioning member includes a wide portion where an external force to be applied accompanying an occupant restraint by the airbag becomes largest. In the partitioning member, slits are formed at portions other than the wide portion. The slits cause the gas to flow into the downstream inflation portion from the upstream inflation portion upon the inflation of the airbag. The slits are opened by the force to increase the flow rate of the gas into the downstream inflation portion from the upstream inflation portion during the occupant restraint by the airbag compared to the gas flow rate before the occupant restraint by the airbag. | 03-27-2014 |
20140151985 | SIDE AIRBAG APPARATUS - An airbag of a side airbag apparatus includes an upstream inflation portion, which inflates by inflation gas, and deploys frontward at a side of a vehicle seat. An opening is provided at a wall portion of the upstream inflation portion. A pressure regulator valve closes before an occupant is restrained by the upstream inflation portion, thereby restricting the inflation gas in the upstream inflation portion from flowing through the opening. Upon the occupant restraint, the pressure regulator valve cancels the restriction in response to a change in a tensed state of the dividing portion by an external force applied due to the restraint. A tear seam that connects valve body portions of the pressure regulator valve delays the opening time of the pressure regulator valve upon the occupant restraint by the upstream inflation portion relative to the opening time set only by the pressure regulator valve. | 06-05-2014 |
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 |
20140210192 | SIDE AIRBAG APPARATUS - An inflation portion of an airbag main body is divided into a first inflation chamber, a second inflation chamber in front of and adjacent to the first inflation chamber with a vertical partition in between, and a third inflation chamber below the first inflation chamber with a lateral partition in between. The vertical partition has a pressure regulator valve. Before the first inflation chamber restrains an occupant, the pressure regulator valve restricts flow of inflation gas from the first inflation chamber to the second inflation chamber. When the first inflation chamber restrains the occupant, the pressure regulator valve opens in response to a change in the tensed state of the vertical partition due to the applied external force generated by the restraint, thereby cancelling the restraint. The lateral partition has a check valve, which restricts flow of inflation gas from the third inflation chamber to the first inflation chamber. | 07-31-2014 |
