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 |
20140042735 | 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. | 02-13-2014 |
20140339797 | 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.
