    • The present invention provides a seat assembly supported by a seat frame that includes a seat cushion, an upwardly extending back cushion, a seat repositioning device, and an actuation mechanism that repositions the seat cushion. In one embodiment, an airbag is disposed beneath a seatpan such that inflation raises a forward portion of both the seatpan and seat cushion. Inflation of the airbag is in response to a sensor detecting the rapid deceleration of the vehicle. The seatpan is attached to each respective armrest of the seat frame at a hinge point that permits the seatpan to rotate upwardly. A seatbelt cinching mechanism is attached to the seatpan such that upward rotation of the seatpan pulls the cinching mechanism around an idler pulley, and thereby increases seatbelt tension. In a second embodiment, an airbag inflates through an opening in the seat cushion and above a forward portion of the seat cushion. In a third embodiment, the airbag is substituted with a gas activated cylinder. As in the first embodiment, rapid deceleration initiates the gas activated cylinder to lift the seatpan upwardly.
    • 本发明提供了一种由座椅框架支撑的座椅组件,座椅框架包括座垫,向上延伸的靠背垫,座椅重新定位装置和重新定位座垫的致动机构。 在一个实施例中,安全气囊设置在座位下方,使得膨胀使坐垫和座垫的前部部分升高。 气囊的充气是响应于传感器检测到车辆的快速减速。 座位板在允许座椅板向上旋转的铰链点处附接到座椅框架的每个相应的扶手。 安全带收紧机构附接到座位板,使得座椅的向上旋转将收紧机构拉到惰轮上,从而增加了安全带张力。 在第二实施例中,安全气囊通过座垫中的开口膨胀并且在座垫的前部上方膨胀。 在第三实施例中,气囊被气体活化气缸代替。 如在第一实施例中,快速减速启动气体活动气缸以向上提升座椅板。
