    摘要： PROBLEM
    To provide a vehicular side airbag device enabling improving occupant restraint performance of the airbag cushion with a simple configuration.
    RESOLUTION MEANS
    An airbag module 106 includes an airbag cushion 108 in a bag shape and in a prescribed rolled or folded storage configuration and an inflator 110 that supplies gas to the airbag cushion 108, and is mounted in a side frame 134 of a seatback 104. The airbag cushion 108 includes a main chamber 112 that expands and deploys from the side frame 134 to the side of an occupant seated in a seat 102 and a sub-chamber 114 that expands and deploys from the main chamber 112 to the occupant side. The edge 116 of the sub-chamber 114 on the occupant side is curved and concave toward the main chamber side.

    摘要： Provided is a vehicle seat that has high designability and achieves control of a deployment speed of a side airbag. A seat (1) includes: a bolster part (4) located on a side of a top board part; a shoulder part (5) located above the bolster part (4); a cover (6) for each the bolster part (4) and the shoulder part (5); and an airbag sleeve (15) provided in the bolster part (4). The airbag sleeve (15) includes; a first section (15a) extending along a first tear line (17) serving as a seam of a first cover piece (11) and a second cover piece (12); and a second section (15b) extending across a second lateral directional line (20) serving as a seam of the second cover piece (12) and a fourth cover piece (14). The first section (15a) is sewn with the second cover piece (12) along the first tear line (17). The second section (15b) is sewn with a set of the second cover piece (12) and the fourth cover piece (14) in such a manner as to enclose and sandwich a seam allowance extending along the second lateral directional line (20).

    摘要： [Problem] To provide a passenger restraining device capable of further improving passenger restraining performance of an airbag cushion.
    [Resolution Means] A passenger restraining device 100 is provided with an airbag cushion 112 stored in a seatback 104 in a predetermined storage form, an inflator 120, and a first belt 116a and a second belt 116b connected to the side of the airbag cushion 112 opposite to the passenger 103 and stored from the inside of the seatback 104 to the inside of a seat cushion 106. The second belt 116b is disposed behind the first belt 116a on the side of the expanded and deployed airbag cushion 112 opposite to the passenger. In a stored state in which the airbag cushion 112 in a storage form is assembled on a frame 122, the first belt 116a is disposed so as to be located farther from the frame 122 than the second belt 116b.
