To satisfy both of prevention of wearing feeling deterioration when an adult wears a seat belt and prevention of separation of the seat belt from the shoulder when a child wears the seat belt during a collision without adding expensive components and separately performing a manual operation.SOLUTION: A pretensioner type retractor 30 is disposed on a rear side of a belt guide 10. A seat belt 40 via the belt guide 10 from the retractor 30 extends obliquely downward from the shoulders of occupants (an adult P1 and children P2) and restrains the occupants. The belt guide 10 has an inside side wall section 14 extending upward at an end on the occupant side. The inside side wall section 14 regulates the seat belt 40 from being displaced by prescribed amount or more toward the occupant side during a normal time. The inside side wall section is elastically deformed by receiving component force directing to the occupant side when tensile force of pretension by the retractor 30 is applied and locates the seat belt at a position where the seat belt is more moved toward the occupant side than the normal time.SELECTED DRAWING: Figure 11

    【課題】高価な部品の追加や別途マニュアル操作を行うことなく、大人が装着したときの装着感悪化の防止と子供が装着したときの衝突時におけるシートベルトの肩外れ防止とを共に満足させる。【解決手段】ベルトガイド10の後方にプリテンショナ式のリトラクタ30が配設される。リトラクタ30からベルトガイド10を経由したシートベルト40が乗員(大人P1、子供P2)の肩部から斜め下方へと延びて乗員を拘束する。ベルトガイド10は、乗員側の端部において上方へ延びる内側側壁部14を有する。内側側壁部14は、通常時はシートベルト40が乗員側に向けて所定以上変位するのを規制する一方、リトラクタ30によるプリテンションの引張力が作用したときに乗員側に向かう分力を受けて弾性変形されて、シートベルトが通常時よりも乗員側に向けて移動された位置とされる。【選択図】 図11
