摘 要
随着国民经济的快速发展，汽车逐渐成为我国目前主要的交通工具之一。汽车座椅是影响舒适性和美观性以及汽车NVH性能的重要组成部分，随着人们对生活品质要求的不断提高，汽车座椅的设计要求不断提出更高的要求，尤其是汽车后排座椅的调节较为单一化，后排座椅调节机构没能普及的原因可能在于缺乏架构合理、便于调节的座椅调节机构。本文首先查并总结了汽车座椅调节机构的发展研究现状，了解重要部件的设计要求，对后排座椅的调节机构进行设计和改进，完成了后排座椅靠背调节和座椅前后及上下四个方向的调节机构的设计，本文设计的汽车后排座椅调节机构易于实现和操作，结构和尺寸在确定后使用三维建模软件CATIA完成整体的部件装配。书本知识活学活用，将汽车后排座椅的调节实现了靠背的角度稳定、流畅的调节以及前后、上下四个方向的调节，在没有采用复杂的无极调节机构的基础上实现了对汽车后排座椅不同方向上的流畅性调节，能够满足不同百分位乘员身体的舒适性，提高了操作舒适性，与此同时本文设计的后排座椅调节机构所采用的材料和零件尺寸都遵循轻量化的原则，尽可能的将后排乘员空间利用率提升至最大。查阅了机械设计手册，学习和掌握了三维建模软件的知识，提高了自身的绘图水平。

Abstract
属鸡的今年多少岁With the rapid development of the national economy, the automobile has gradually become one of the main means of transportation in China. Car seats are comfortable and beautiful sex and harshness (NVH) performance is an important part of, with the continuous improvement of people's life quality requirements, the design requirements of car seat continuously put forward higher request, especially the car rear seat is simplified and the regulation of the rear seat regulator failed to universal reason may lie in the lack of structure is reasonable, easy to adjust the seat adjustment mechanism. At first, this paper finds and summarizes the development and research status of automobile seat adjustment mechanism, understand the important parts of the design requirements, adjusting mechanism of the rear seat design and improvement, completed the rear seat backrest and seat before and after the adjustment and the regulating mechanism in the direction of up and down four design, this paper design the car rear seat regulating mech
anism is easy to realize and operation, the structure and dimension after determined using three-dimensional modeling software CATIA to complete the whole assembly of parts. Book knowledge learning, to the rear seat of the car regulation can adjust the backrest Angle stability, fluent and, before and after the adjustment of the four directions, up and down without using the non-polar adjusting mechanism on the basis of realizing the complex flow of different directions in car rear seat adjustment, able to meet the percentile occupant comfort of the body, improve the operating comfort, at the same time this paper design the rear seat used by regulating mechanism of materials and parts size is in line with the principles of lightweight, as far as possible to the rear occupant space utilization up to the maximum. The manual of mechanical design is reviewed, the knowledge of 3d modeling software is studied and mastered, and the drawing level is improved.
