PROBLEM TO BE SOLVED: To provide an occupant restraint capable of more surely restraining the waist part at the time of a front crash than before.SOLUTION: A restraint 10 for the waist part of a sitting person is provided for restraining a forward movement of the waist part of a sitting person by elevating a seating surface 2a of a seat part 2 of a vehicle seat 1 in correspondence with a front crash in a state of a waist part seat belt 20b of the vehicle seat 1 being fastened. The elevation shape of the seating surface 2a of the restraint 10 for the waist part of a sitting person in correspondence with the front crash is in a convex shape having a ridge line part 2ad extending in a vehicle front-rear direction at a substantially center position in a width direction of the seat part 2. Further, the height and width of the ridge line part 2ad gradually increase as extending from the vehicle rear side to the front side. Thereby, at the time of a front crash, the waist part of a sitting person S is restrained from being moved forward in a manner riding onto the ridge line part 2ad. Also, due to the ridge line part 2ad, a horizontal movement of the thigh part is restrained and thereby the horizontal movement of the waist part is also restrained.SELECTED DRAWING: Figure 7

    【課題】前突時に従来よりも腰部を確実に拘束しうる乗員拘束装置を提供すること。【解決手段】車両用シート1の腰部シートベルト20bの装着状態で、前突に対応して車両用シート1のシート部2の座面2aを隆起させて着座者の腰部の前方移動を抑制する着座者腰部拘束装置10である。着座者腰部拘束装置10の前突に対応した座面2aの隆起形状が、シート部2の幅方向略中央位置で車両前後方向に伸長する稜線部2adを有する凸状形状であり、稜線部2adの高さ及び幅が、車両後方から前方に移行するにつれて漸次増大することを特徴とする。これにより、前突の際には着座者Sの腰部がこの稜線部2adに乗り上げる形で前方移動が拘束され、且つ、この稜線部2adによって大腿部の左右への移動が拘束され、腰部の左右移動も拘束される。【選択図】図7
