摘要

人们在生活和工作时，离不开座椅，特别是以坐姿进行工作的人，每天都有1/3以上的时间在与座椅打交道。因此座椅设计除了材料运用得当及造型大方美观以外，更重要的是要符合人体工学设计原则，即进行座椅设计时必须充分考虑人体的坐态生理特征。让坐在其上的人可以得到更好的状态。

人最自然的姿态是直立站姿，直立时脊柱基本上呈S形，不过与之相比，坐姿更有利于身体下部的血液循环，可以减少下肢的肌肉疲劳感。但是人们坐着时，骨盆向后方倾转，因而使得背下端的骶骨产生倾转，使脊柱由S形（正常状态）向拱形变化，使得椎间盘受到很大压力，从而导致腰痛等疾病。因此，座椅设计要保证椎间盘压力最小。

座椅与人们的生活息息相关，无论是工作、学习、出门旅行、在家休息都离不开座椅。关于座椅的设计问题至今仍是值得研究的课题。从50年代初，美国的科甘对整形外科的医用座椅进行研究以后，40多年来关于座椅的设计问题已有多位学者进行过系统科学的研究，各种设计参数也相继见于诸多资料。但就目前来看，尚不能说一把真正获得公认的理想的舒适座椅已经问世。这是因为人体的坐姿是个相当复杂的问题。比如，从事长时间体力劳动的人能坐上一只木板凳休息，则会感到非常舒适，而对于常年日工作量8h且取坐姿工作的人(秘书、打字员等)任何一种座椅都不会被认为是完美无缺的。

综上所述，座椅的设计是很复杂的问题，要想设计出一把被公认为理想的舒适座椅几乎是不可能的。因而要想设计出一把相对理想的座椅必须根据使用目的进行多种因素的考虑。

Abstract：

Seats with people's daily lives, whether it is work, study, to travel, to rest at home are inseparable from the seat. Design problems on the seat is still worthy of some research. From the early '50s, the United States Cogan pairs of plastic surgery research for medical seat after 40 years on the seat design problems have been a number of scholars to conduct a systematic scientific research, various design parameters have also seen a lot of information on . But for now, still can not say that one will really be recognized as an ideal comfortable chairs have been around. This is because the body's posture is a rather complex problem. For example, people who engage in prolonged physical work can sit a Muban Deng rest, would be very comfortable, but for all year round on the workload of 8h and the work of the seated person (secretary, typist, etc.) any kind of seat will not be considered to be perfect.

In summary, the seat design is a very complex issue, in order to design a widely recognized as an ideal comfortable seat is almost impossible. To design and therefore a relatively good seats must be based on the use of purpose of a variety of factors into account.
