后排座椅四连杆机构的连接支架杆同心安装结构
本技术属于汽车座椅
,具体涉及一种后排座椅四连杆机构的连接支架杆同心安装结构。
技术介绍
后排座椅上设置有四连杆机构,用于实现靠背放平的同时座框下沉,其中靠背骨架与座框骨架有两个铰接点,座框骨架的前端通过前连接杆与底座相连,前连接杆的上下两端各为一个铰接点,共四个铰接点。对于靠背骨架与座框骨架有两个铰接点,其中一个为靠背骨架与座框骨架直接铰接,另外一个为座框骨架通过座框后连接杆与靠背骨架间接铰接。对于间接铰接点,在座椅的两侧分别做两个大销轴,将座框后连接杆固定在靠背骨架的边板上,同心度无法保证,强度也不够。
技术实现思路
本技术旨在将靠背骨架与座框骨架的间接铰接点通过同一连接支架杆相连,从而确保左右两侧铰接点的同心度。为此,本技术所采用的技术方案为:一种后排座椅四连杆机构的连接支架杆同心安装结构,包括靠背骨架和座框骨架,所述靠背骨架与座框骨架通过第一铰接点相连,座框骨架左右两侧的后端分别固连有座框后连接杆,两个座框后连接杆的后端向上弯折并通过贯通靠背骨架的同一连接支架杆活动连接,构成了靠背骨架与座框骨架的第二铰接点,且第二 ...
