汽车安全气囊 摘要 。关键词SummaryThe automotive airbag is a passive safety system devices. Popular simple to say, protection is not active, only after the discovery of the collision, the system will work. Airbag sensors, microprocessors, gas generator and air bag components. Sensors and microprocessors used to determine the extent of the crash, transmission, and sends a signal; gas generator according to the signal indication ignition action, to ignite the solid fuel and the production of gas to the air bag inflated, the airbag rapid expansion, airbag capacity of about (50-90) L,. The airbag has a safety valve will automatically discharge the part of the gas, to avoid to squeeze the passengers were injured when over-inflated or intraluminal pressure exceeds a certain value. Used in airbag gas is nitrogen or carbon monoxide. The automotive airbag in the event of a collision, a very short period of time, the ECU issue ignition instructions, the gas generator initiation to release the gas After rebooting the airbags to break through the cover and the formation of a bag body, to make like the pediment of the crew does not hit the steering wheel or on the dashboard or other car parts. Is actually a process of energy with energy constraints, popular is violence with violence, so passive. Airbag deployment, a bag body (like an inflated balloon), to offset a large part due to collision and passengers forward momentum and energy, so as to achieve a protective effect.Keywords: collision sensor buffer airbag gas generator control block (computer) 目录 第一章 汽车安全气囊的发展 　 1.1安全气囊简介 　 1.2安全气囊的发展 　　1.3安全气囊的发展趋势 第二章 安全气囊的工作原理 　　2.1 安全气囊系统的组成及特点 　　2.1.1安全气囊的组成 　　2.1.2安全气囊的特点 　　2.2 安全气囊的作用与分类 　　2.2.1 安全气囊的作用 　　2.2.2 安全气囊的分类 2.3 安全气囊的工作原理 第三章 汽车安全气囊的应用 　　3.1 安全气囊的工作过程 　　3.2 启爆安全气囊的条件 　　3.3 使用安全气囊注意事项 　　3.4 安全气囊的缺陷 3.5 安全气囊的拆装及维护 总结 参考文献 第一章 汽车安全气囊的发展 1.1安全气囊简介 　　安全气囊系统称为SRS，相对于安全带，安全气囊只是一个辅助保护设备。安全气囊是用带橡胶衬里的特种织物尼龙制成，工作时用无害的氦气填充。它主要分布在车内前
