<p>In order to further improve a capability for restraining an occupant (14) by absorbing inertia force of a head portion (14H) in a vehicle-width direction, by means of an expansion portion (18), by far largely expanding the expansion portion (18) in an upper and lower direction of motor vehicle at a position facing the head portion (14H) of the occupant (14) in the vehicle-width direction in a side collision, while securing usability of a webbing (16) for occupant restraint in an ordinary use, a belt guide (20) provided on a slanting portion (22) (shoulder portion) of a seatback (26) in a vehicle seat (12), is capable of being developed in a direction being spaced apart from the head portion (14H) up to a predetermined angle limited by means of stopper portions (40S, 42S), around a fulcrum (36) positioned at an outside in a vehicle-width direction as a center, from an ordinary condition, in which the webbing (16) for occupant restraint is guided, at a time when the expansion portion (18) is expanded. Accordingly, it is enabled for the expansion portion (18) to be expanded toward an upper position facing the head portion (14H) in the vehicle-width direction, while limiting an expanding shape of the expansion portion (18).</p> |
