Car seat system is used to driving in the car who support and facilitate the access and drive to ensure the operation of driving under the premise of providing effective seat driving system should expect to provide adjustable and longdistance driving fort. In the door closed, adjust the seat the entire trip, the seats should be suitable for operation of the system to carry out all the body driving control operation intuitive. At the same time protect the car seat is also part of vehicle safety performance. Car seat design and the quality of the reasonableness of a direct impact on passenger safety and fort.The bination of ergonomic design, as well as the main seat of the national standards for small passenger seat of the structural design and analysis. According to various parts of ergonomics to determine the size of the pletion of the structure adjustment, according to relevant national standards for the design of rational analysis and a static analysis.The design of the regulating agencies, including before and after adjusting the main body, a high degree of regulation of agencies and institutions regulating the design point of view, the design of its structure and working principle.The seat is designed to minivan production and provides a reference experiment, the actual production of a certain degree of guidance.Keywords: chairs, ergonomics, structure, static analysis本科生畢業(yè)設(shè)計(jì)（論文）III目 錄第 1 章 緒 論 ...........................................................................................................1 小型客車(chē)座椅的功用及設(shè)計(jì)要求 ............................................................1 小型客車(chē)座椅的功用 .....................................................................1 小型客車(chē)座椅的設(shè)計(jì)要求 ..............................................................1 小型客車(chē)座椅結(jié)構(gòu) .................................................................................
