<p>An ability of a side airbag to initially restrain the shoulder of an occupant is improved. In a vehicle side airbag device (10), when a side airbag (20) is inflated and deployed, a tension cloth (26) disposed bridging an upper side bag portion (34) and a lower side bag portion (36) on the vehicle width direction outer side of the side airbag (20) is pulled up and down. Because of this, the vehicle width direction inflation width of the side airbag (20) is enlarged, so the vehicle width direction shock absorbing stroke can be ensured by the small-capacity side airbag (20). Moreover, the tension cloth (26) functions as a reaction force surface that supports the upper side bag portion (34) from the outer side in the vehicle width direction, so even in a vehicle in which the position of a door beltline (49) is low, a shoulder (S) of an occupant (P) can be restrained at an early stage. Furthermore, in a case where the vehicle has rolled over, the tension cloth (26) protects the side airbag (20) from fragments of a door glass (50).</p> |
