汽车安全气囊概述和机械式气囊

Brief Introduction on Car Safety Air Bag and Mechanical Air Bag

汽车安全气囊按控制类型不同，可分为机械式和电子控制式两类。本文重点介绍电子控制式安全气囊的分类；对安全气囊工作可靠性进行了分析；阐述了目前国外已开发出比电子式气囊更简单、更廉价的机械式安全气囊的工作原理。

According to the different controlled types, car safety air bags can be divided into mechanically controlled type and electrically controlled type. This paper puts emphasis on introducing the classification of the electrically controlled safety air bag and analyses its working reliablity, and expounds the principle of the mechanical type which is simpler and cheaper than electrical one.
