乘用车座椅的设计 摘要：随着现代经济的飞速发展，汽车成为人们生活的必需品，人们对汽车的舒适性和安全性有了更高的要求，座椅是影响汽车的舒适性和安全性主要的一部分，本文通过对乘用车座椅的结构、性能、设计要求等对座椅的乘坐舒适性进行分析—建模—数据分析—设计—评估；对安全性进行分析—建模—试验—结果分析—设计，安全带作为座椅安全的主要配置，提出在车上装配安全气囊的情况下，安全带在一定条件下的断裂及座椅在一定条件下的移动变形，更有助于对乘员的保护。进而提出在综合考虑与安全气囊匹配的情况下，安全带该断就断、座椅该动就动的新的设计理念，最后介绍了CAD在座椅设计中的应用。 关键词：舒适性；安全性；人机工程学；CAD The Design Of Passenger Seats  Abstract：With the rapid development of modern economy, car has become a necessity for peoples lives, Peoples car comfort and safety have higher requirements, Affecting the car seat comfort and safety of the main part of this paper, the structure of the passenger seat, performance, design requirements, such as seating comfort analysis - modeling - data analysis - Design - Evaluation ; of security analysis - Modeling - Testing - Analysis - Design, safety seat belts as the main configuration, the airbag assembly in the vehicle, the seat belts under certain conditions, and the seat of the fracture under certain conditions, the movement and deformation, but also contribute to the protection of the crew. Proposed to consider the matching with the airbag, the seat belt on the broken off, seats that move on the dynamic new design concept, and finally introduced in the seat design of CAD applications.
