技术领域technical field
本发明涉及汽车座椅技术领域，更具体地说，涉及一种腰背部气动支撑装置及汽车座椅。The invention relates to the technical field of car seats, and more specifically, relates to a low back pneumatic support device and a car seat.
背景技术Background technique
随着车辆交通领域的科技发展，人们对于车辆乘坐舒适性的要求越来越高。一种座椅的腰背部支撑技术也应运而生，并逐步应用于中高端乘用车辆领域。With the development of science and technology in the field of vehicle transportation, people have higher and higher requirements for vehicle ride comfort. A lumbar back support technology for seats also emerged as the times require, and has been gradually applied to the field of mid-to-high-end passenger vehicles.
以往，此类座椅腰托支撑技术通常使用机械支撑和气动支撑两种技术形态。气动支撑是采用微型的气泵作为动力源将空气经过相关控制阀体，吹入置于座椅靠背发泡垫后部的顶撑气囊体内，通过气囊体的充放气，实现靠背座椅椅面的局部凸起或平伏，进而实现对人体的腰背部支撑作用。In the past, this type of seat lumbar support technology usually used two technical forms of mechanical support and pneumatic support. Pneumatic support uses a miniature air pump as the power source to blow air through the relevant control valve body and into the top support air bag placed at the back of the foam cushion of the seat back. The local bulge or flatten, and then achieve the role of supporting the human body's lower back.
此类座椅顶撑气囊产品的一个简单应用，就是将一个顶撑气囊，布置在靠背支撑簧架与靠背发泡垫之间的塑料支撑背板之上。当顶撑气囊被气泵充气时，顶撑气囊被充气而产生凸起行程，进而将靠背发泡垫向前顶起，进而使得靠背椅面前方发生凸起。A simple application of this type of seat top support airbag product is to arrange a top support airbag on the plastic support backboard between the backrest support spring frame and the backrest foam cushion. When the support airbag is inflated by the air pump, the support airbag is inflated to produce a convex stroke, and then the backrest foam cushion is pushed forward, thereby causing the front of the backrest to bulge.
然而，凸起的顶撑气囊在向椅面前方顶起的同时，顶撑气囊会顶压在靠背发泡垫上，并在一定程度上易于陷入相对较软的靠背发泡垫的后部。当靠背发泡垫的垫体厚度偏薄时，其造成的结果是，各个顶撑气囊充气后，被充气的顶撑气囊顶压面使得座椅靠背椅面出现不够平顺，乘员腰部有突兀感现象，容易引起座椅使用者的不满。这种突兀的不平顺现象，对于采用较大椅面支撑行程的多级气囊的顶撑气囊的气动背部支撑调节装置来说尤其明显。However, when the raised top support airbag pushes up towards the front of the seat, the top support airbag will press against the backrest foam cushion, and to a certain extent, it is easy to sink into the rear portion of the relatively soft backrest foam cushion. When the cushion thickness of the backrest foam cushion is relatively thin, the result is that after each top support airbag is inflated, the pressure surface of the inflated top support airbag makes the seat back surface not smooth enough, and the occupant's waist feels abrupt. Phenomenon, it is easy to cause dissatisfaction of seat users. This abrupt uneven phenomenon is particularly obvious for the pneumatic back support adjustment device of the top support air bag of the multi-stage air bag that adopts a larger seat surface support stroke.
因此，如何避免座椅靠背的椅面出现不够平顺的问题，成为本领域技术人员亟待解决的技术问题。Therefore, how to avoid the problem that the seat surface of the seat back is not smooth enough has become a technical problem urgently to be solved by those skilled in the art.
