The invention provides a safety airbag which is used as a main driving airbag of a vehicle. The safety airbag comprises a main airbag and auxiliary airbags. The main airbag has an approximately circular cross section. The auxiliary airbags are attached to the left and right sides of the main airbag in a diameter direction of the main airbag. Each auxiliary airbag has a crescent-shaped cross section, and an air leakage hole is formed in the opposite face of the face away from the passenger. The main airbag is provided with exhaust channels leading to the auxiliary airbags. According to the safety airbag, air in the main airbag can be exhausted to the auxiliary airbags through the exhaust channels to be reused in the process that a driver makes contact with the safety airbag, the auxiliary airbags protect the driver, and particularly the head of the driver is protected in offset collision; besides, the safety airbag more matches a conventional steering wheel structure, and after an accident happens, the steering wheel can provide a more stable supporting effect for the safety airbag.

    本发明提供一种安全气囊,其用作车辆的主驾驶安全气囊。安全气囊包括主气囊和副气囊。其中,主气囊具有大致呈圆形的横截面。副气囊分别沿主气囊的直径方向附接于主气囊的左右两侧。副气囊具有月牙形横截面,且在背离面朝乘客一面的相对面设有泄气孔。主气囊设有通向副气囊的排气通道。本发明的安全气囊可以在驾驶员与其接触过程中通过排气通道将主气囊的气体排出到副气囊,进行再次利用,副气囊对驾驶员提供保护,尤其在偏置碰撞中对驾驶员头部提供保护作用;此外,该类型的安全气囊与常规的方向盘构造更为匹配,发生事故后,方向盘能够对安全气囊提供更稳固的支撑作用。
