Abstract

A vehicle seat includes: a seat frame; a seat cover provided with a rupture portion; an airbag disposed in the seat; a pair of webbings provided so as to surround the airbag on a back surface side of the seat cover, one end sides of the webbings being mounted to the rupture portion; and a mounting section mounting the other end sides of the webbings to the seat frame. In a vehicle collision, the airbag is protruded out of the seat by rupturing and opening the rupture portion. The mounting section is provided at a place where a body of the seat frame is disposed. When the airbag is uninflated, the mounting section holds the other ends of the webbings apart from the body of the seat frame, and an inhibition portion in the mounting section inhibits contact between an edge-shaped portion formed in the body and the webbings.
