The invention relates to an automobile seat waist supporting mechanism which comprises an automobile seat body, and an adjusting mechanism is arranged at the top of the automobile seat body. The adjustable backrest has the beneficial effects that when a user needs to adjust the angle of the seat backrest, the inclination of the adjustable backrest body can be manually adjusted firstly, then the micro transmission pump is started, air is conveyed into the air bag through the communicating pipe, the user can sit on a trial to ensure optimal matching of waist support, and after the user is adjusted to an ideal state, the user can sit on the waist support. In the running process of the vehicle, if braking occurs and a user inclines forwards due to the inertia effect, the back can apply pressure to a plurality of adjusting air bags, after the adjusting air bags are pressed, a mounting plate is driven to apply force to a fixing plate, the fixing plate is made to generate displacement, the force is transmitted to a protection plate step by step, and the protection plate further transmits the pressure to a reset spring; the reset spring effectively buffers impact on the waist and the back of the user during braking by absorbing impact force.

    本发明涉及一种汽车座椅腰部支撑机构,包括汽车座椅本体,汽车座椅本体的顶部设有调节机构;本发明的有益效果是:当使用者需要调整座椅靠背角度时,可先手动调节可调节靠背本体的倾斜度,随后启动微型传输泵,利用连通管将气体输送至气囊内部,使用者可进行试坐,以确保腰部支撑的最佳匹配,当调整至理想状态后,即可进入驾驶状态,在车辆行驶过程中,若发生刹车,使用者因惯性作用向前倾斜,后背会对多个调节气囊施加压力,调节气囊受压后驱动安装板向固定板施力,使固定板产生位移,并将力逐级传递至防护板,防护板进一步传递压力至复位弹簧,复位弹簧通过吸收冲击力,有效缓冲刹车时对使用者腰部及背部的冲击。
