The invention provides an automobile seat emergency protection device for automobile head-on impact. The device is connected with a head anti-collision beam on an automobile. The device comprises a base, a cushion, a backrest, a linkage rod, a rotating shaft, an adjusting gear, an adjusting rod, clamping teeth, a first spring, a rotating gear and a rack. The cushion is fixedly arranged on the base, the adjusting gear is hinged to the cushion through the rotating shaft, the backrest is fixedly connected with the adjusting gear through a rotating arm, and the middle of the adjusting rod is hinged to the base. When a front impact occurs, the impact enables the anti-collision beam of an automobile head to be sunken inwards, the anti-collision beam can move inwards straightly through a linkagerod, then the rack drives a rotating gear to rotate, the backrest is turned backwards to be in a lying state, and at the moment, a human body lies backwards along with the backrest under a constraintof inertia and a safety belt. At the moment, even if a steering wheel and an instrument panel invade a cab, fatal damage to key parts of an upper body of a driver is avoided, and the human body is effectively protected.

    本发明提供一种汽车正面撞击的汽车座椅紧急防护装置,与汽车上的头部防撞梁相连,包括底座、坐垫、靠背、联动杆、转轴、调节齿轮、调节杆、卡齿、弹簧一、转动齿轮、齿条,所述坐垫固定设置在底座,所述调节齿轮通过转轴铰接在坐垫上,所述靠背通过转动臂与调节齿轮固连,所述调节杆的中部铰接在底座上。当遇到正面撞击时,撞击会使车头的防撞梁向内凹陷,防撞梁就会通过联动杆径直向内移动,然后齿条带动转动齿轮转动,使得靠背向后翻转至平躺状态,此刻人体在惯性和安全带的束缚下,跟随靠背向后躺下。此刻,即使方向盘和仪表盘入侵驾驶室,也不会对驾驶员的上半身人体要害部分造成致命伤害,对人体形成有效的防护。
