<p>There is obtained a side airbag device for a vehicle in which an upper arm portion of a seated passenger becoming interposed between a chest portion of the seated passenger and a side airbag can be suppressed, and that can restrain a shoulder portion of the seated passenger well by a side airbag regardless of a form of a side collision. In an inflated and expanded state of a side airbag (20), a forwardly extending portion (32B), that is provided at an upper portion of a rear side bag portion (32), extends from a side of a shoulder portion (S) of a seated passenger (P) toward a vehicle front side and is disposed above a front side bag portion (30). A dimension in a vehicle transverse direction of this forwardly extending portion (32B) is set to be smaller than that of the front side bag portion (30), and a vehicle transverse direction inner side surface at an upper end side of the front side bag portion (30) is inclined or curved so as to rise-up while heading toward a vehicle transverse direction outer side. An upper arm portion (A) is pushed-up due to sliding contact with this surface. Moreover, even when the seated passenger (P) inertially toward an oblique front of a vehicle, the shoulder portion (S) can be restrained by the forwardly extending portion (32B).</p> |
