The invention provides a seat backrest emergency floating device which comprises a seat backrest, a movable plate and a storage tank, a containing cavity with an opening is formed in the seat backrest, and the movable plate is arranged in the containing cavity and can move towards the opening direction of the containing cavity under the action of external tension. The storage tank is fixed to the end, away from the movable plate, of the seat backrest and communicates with the containing cavity, and foaming agents are contained in the storage tank. The daily movable plate is located in the containing cavity to provide support, stability of the seat backrest is guaranteed, when the vehicle encounters the danger of falling into water, the seat backrest can be detached, the movable plate is rapidly pulled out of the containing cavity, meanwhile, the storage tank is opened, the foaming agent is rapidly released and rapidly fills the whole containing cavity, and the seat backrest is supported; the movable plate and the foaming agent are both buoyancy materials and can provide buoyancy for the whole seat backrest to enable the seat backrest to become an emergency floating plate, so that a person in distress can quickly emerge from the water surface through the floating plate at the first time and can float on the water surface for a long time to wait for rescue.
本发明提供了一种座椅靠背应急漂浮装置,包括座椅靠背、活动板材和存储罐,座椅靠背内部形成具有开口的容纳腔,活动板材设置于容纳腔内并能够在外部拉力的作用下向容纳腔的开口方向移动,存储罐固定于座椅靠背远离活动板材的一端并与容纳腔连通,其内部有发泡剂;日常活动板材位于容纳腔内提供支撑,保证座椅靠背的稳定,当车辆遭遇落水险情时,可拆卸座椅靠背,将活动板材快速拉出容纳腔,同时存储罐被打开,发泡剂快速释放并迅速填充整个容纳腔,对座椅靠背实现支撑,活动板材和发泡剂均为浮力材料,能够为整个座椅靠背提供浮力,使其成为应急漂浮板,从而遇险人员能够第一时间利用漂浮板快速浮出水面,且能够长时间漂浮于水面上以等待救援。
