在全球汽车制造业及美国的政府机构(NHATSA)的共同努力下,已经认可汽车安全气囊与安全带一起使用时,汽车发生前碰撞时对拯救乘员生命方面是有效的。在过去的几年中,安全气囊仅能装备在豪华汽车上。目前由于技术的发展,加上法规对汽车安全性要求日趋完善,已经有条件把它作为一种标准装
With the joint efforts of the global automotive industry and the U.S. government agencies (NHATSA), it has been recognized that when a car’s airbag is used in conjunction with a seat belt, the car’s frontal collision is effective in saving the lives of occupants. In the past few years, airbags can only be equipped with luxury cars. At present, due to the development of technology, coupled with the increasingly stringent requirements of laws and regulations on automobile safety, it has been qualified as a standard equipment
