The invention relates to a safety airbag device capable of adjusting internal pressure. The safety airbag device comprises an airbag body and a mounting shell thereof, a first air leakage hole is formed in the air bag body; the device is characterized in that the device is provided with a base; a second air leakage hole is formed in the air bag body; the airbag body is internally connected with anair leakage assembly corresponding to the second air leakage hole; a release mechanism controlled by an ECU is arranged on the mounting shell, one end of the air leakage assembly is connected with the release mechanism through a pull belt, and the air leakage assembly is released by the release mechanism when a vehicle is in head-on collision and the body proportion of a driver and passengers issmall, so that the second air leakage hole is opened, and rapid air leakage is achieved. The safety airbag device has the beneficial effects that the ECU controls the ignition action of the gas generator of the release mechanism, so that the gas release assembly is released by the release mechanism, the second gas release hole is opened, high-pressure gas inflated into the airbag body is discharged more quickly through the first gas release hole and the second gas release hole, the internal pressure of the airbag is reduced, and the personal safety of drivers and passengers is protected.

    本发明涉及一种可调节内压的安全气囊装置,包括气囊本体及其安装壳体,在气囊本体上设有第一泄气孔,其特殊之处是:在气囊本体上设有第二泄气孔,气囊本体内对应第二泄气孔处连接有泄气组件,在安装壳体上设有通过ECU控制的释放机构,所述泄气组件一端通过拉带与释放机构连接,用于当车辆发生正面碰撞且驾乘人员身材比例较小时,所述泄气组件被释放机构释放,从而将第二泄气孔打开实现快速泄气。有益效果为:通过ECU控制释放机构的气体发生器点火动作,使泄气组件被释放机构释放,从而将第二泄气孔打开,使充入气囊本体内的高压气体通过第一、第二泄气孔更快速的排出,从而降低气囊内部压力,保护驾乘人员的人身安全。
