To obtain a vehicle seat belt device which can inhibit occurrence of a submarine phenomenon of occupants including an occupant in a relaxed state upon a forward movement collision, and which can be improved in weight reduction and mountability.SOLUTION: A buckle 14 is provided between an anchor 22 and a pretensioner 16 via a load transmission member 18. When the pretensioner 16 is activated, and a seat front-side end part of the load transmission member 18 is pulled into the inside of the pretensioner 16, the buckle 14 is pulled in substantially to a seat lower side by an intermediate part 18B. Thereby, a lap belt 20 is directly pulled in substantially to the seat lower side. As a result, even when an occupant P takes a relaxed posture, and thus, a waist part L of the occupant P is tilted backward, a pelvis is tilted forward from the point of the lap belt 20, thereby preventing the waist part L from coming off from the lap belt 20. Accordingly, since the buckle 14 can be directly pulled in by the load transmission member 18 having flexibility and extending in a seat longitudinal direction, the whole of a device can be made compact.SELECTED DRAWING: Figure 2
【課題】安楽状態の乗員も含めて前方移動衝突時にサブマリン現象の発生を抑制できると共に、軽量化と搭載性を向上させることができる車両用シートベルト装置を得る。【解決手段】アンカ22とプリテンショナ16との間に荷重伝達部材18を介してバックル14が設けられている。プリテンショナ16が作動して荷重伝達部材18のシート前方側の端部がプリテンショナ16の内部に引き込まれると、中間部18Bによってバックル14が略シート下方側へ引き込まれる。このため、ラップベルト20が直接的に略シート下方側へ引き込まれるため、安楽姿勢をとることで乗員Pの腰部Lが後傾している場合でも、ラップベルト20を起点に骨盤が前傾してラップベルト20から腰部Lが外れ難くなる。以上より、可撓性を有するシート前後方向に延設された荷重伝達部材18によってバックル14を直接的に引き込むことができるため、装置全体をコンパクトにすることができる。【選択図】図2
