摘要:正如大家都知道的，中国的汽车产业起步较晚，技术落后，缺乏研发能力等方面长期存在的问题没有解决原则。汽车产生之初，最高车速极低，道路系统也不发达，比起马车来都要安全很多，人们尚且不用担心交通事故的问题。但汽车从未停止过加速的脚步，与之而来的即是不断增多的汽车交通事故及其造成的大量人员伤亡，当交通事故的数量逐步累积的时候，汽车安全技术也就应运而生。汽车安全技术关乎人员的生命，是当今汽车技术的重要研究发展领域，也是多个学科的交叉点。汽车安全技术的发展水平在某种意义上说可以代表整个汽车工业的发展水平。然而汽车在为人们带来便利的同时，也带来了令人担心的副作用——安全问题。随着中国汽车产业的快速发展，汽车的驾驶舒适性和安全性的要求越来越高。汽车座椅主要是承载乘客的身体，乘员和汽车内部结构之间的碰撞被称为二次碰撞，由于惯性作用，当车速急降时，司乘人员仍保持原有的速度向前运动，于是就发生了乘员和方向盘、仪表板、挡风玻璃等之间的碰撞，从而造成司乘人员伤亡的严重后果。因此，为了给乘客提供舒适和安全的乘坐体验，一个座椅的设计是否成功，对乘客乘坐舒适性及安全性等有很大的影响，务必要从各方面综合地考虑，只有这样才能设计生产出成功的座椅。

　　本论文分析了人与座椅的人机关系，并且结合我国国民对汽车座椅的使用要求，以座椅结构和力学的理论为依据，以国家和国际标准为准则，对车辆紧急状况和碰撞中作综合设计与静力分析。

ABSTRACT:The principle of China's auto industry started late, backward technology, lack of R & D capabilities longstanding problem is not resolved. The car the beginning of the generated of, the highest vehicle speed is extremely low, the road system is nor developed, compared to the horse-drawn carriage 's the past going to secure a lot of, the people Shangqie do not have to worry about the problem of traffic accidents. But the car has never stopped too accelerate the footsteps of, with it comes that is, the a large number of personnel of the constantly number of for Motor Car Traffic Accident and its caused by the casualties, When the number of traffic accidents gradually the cumulative when, the Automotive Safety Technology also came into being. Automotive Safety Technology relates to the lives of persons is the an important research of the of today's automotive technology the field of development, the cross point of is also the a multiple of disciplines. In a sense, the level of development of the Automotive Safety Technology said that can on behalf of  the level of development of the entire the automotive industry. However, the automotive in the for people to bring convenient at the same time, has also brought the What is worrying side effects of - security issues. With the rapid development of the China's automobile industry, the comfort and safety of the driving of the car the requirements of the sexual is increasingly high. Car seat is mainly is to bearer the's body of the passengers, the collision between the occupant and the automotive the internal structure of is referred to as the secondary collision, due to inertia the role of, When the the drop of vehicle speed when, the Secretary for and passengers are still to maintain a the original the speed of forward movement of the, so took place the collision between the in the occupant and steering wheel, instrument panels, windshield, and so on, resulting in the Secretary for multiplier the the serious consequences of the casualties of personnel. Therefore, in order to the provided to the passengers. The ride experience of the comfortable and safe, a the whether the the design of the seat is successful, on passengers ride comfort and safety of, and so on has a great influence, be sure to you want to the all aspects of the consolidated to consider, the only way in order to design and production out of the success the seat.

　　In this thesis, analysis the man-machine the relationship between of the between man and the seat, and the combination of the use of requirements of our country nationals on the car seat, in order to the of seat structure and mechanics theory and as the basis to, as a criterion in order to the national and international standards, emergency position and collision of the of the vehicle the Sino-make a comprehensive design and the static analysis.
