Abstract: A vehicle seat includes a seat cushion, a seat back having a side support, a frame sidewall in the side support, and a side airbag device. The side airbag device has an airbag in the side support, and an inflator for supplying a gas to the airbag. The airbag has a first chamber to be deployed toward a vehicle front side, a second chamber, and an inner vent hole at a partition between the first and second chambers. The second chamber starts to be deployed prior to the deployment of the first chamber. The gas flows from the second chamber to the first chamber via the inner vent hole. When the second chamber is deployed, at least one of an upper region or a lower region of the second chamber protrudes toward the vehicle front side than a middle region of the second chamber.

Abstract: The present invention is a side airbag device stowed in a seatback of a vehicle seat, comprising: an inflator arranged on the occupant side of a side frame which is positioned on a side part inside the seatback, that generates expansion gas, and an airbag which expands due to said expansion gas and protects the occupant seated in the vehicle seat. The airbag includes a main chamber that deploys toward the front of the seatback, and a pre-chamber that houses the inflator inside and is connected to the occupant side of the main chamber. Furthermore, an integral joint without gaps is formed by sewing between at least the front edge part of the pre-chamber and the main chamber.

Abstract: An improved modularization of an airbag cushion covered with a cover member and a method for manufacturing the same are disclosed. A first press is performed on the first portion of the cover member in a state where the folded airbag cushion 30 is not covered with the cover member. The first portion has at least a portion that includes a position corresponding to an inflator within the folded airbag cushion. Next, the folded airbag cushion is covered with the cover member, and in the covered state, a second press is applied to at least a part of the second portion of the cover member excluding the first portion.
