The present invention relates to a forward shift linkage massage chair frame, including legs foot frame, cushion frame, backrest frame, landing frame, electric push rod and opening bar group, and the opening bar group is set between the lower end of the backrest frame and the front of the cushion frame, and the lift of the cushion frame and leg frame driven by the backrest; and it also includes a sliding frame and a linkage bar group. The sliding frame and the landing frame are sliding and positioned, and the sliding frame driven by the electric push rod can move forward and backward along the landing frame; the rear of the cushion frame and the middle and lower part of the back frame are positioned at the back of the sliding frame through the pin shaft, and the linkage group is set between the lower end of the backrest and the front of the sliding frame, and through the linkage rod group, the backrest frame is fixed around the pin shaft. The loci oscillate, and the angle adjustment is realized. The invention adopts an electric push rod to provide the moving power of the cushion frame and backrest frame. The back frame does not occupy the rear space when the back frame is adjusted, and then cooperates with the opening bar group and the linkage bar group, and synchronously realizes the linkage adjustment of the cushion frame and the leg foot frame, and simulates the zero gravity state.

一种前移联动按摩椅架
:本专利技术涉及一种前移联动按摩椅架,尤其是一款采用单根电动推杆驱动的按摩椅架。
技术介绍
:现有按摩椅的种类繁多,各具有特色,动作越多采用的电动推杆数量也越多,为此,制造业者为了简化制作难度和成本,开发出L形坐靠连体架的方案,虽然靠背垫与坐垫间夹角无法调节,但依然可以实现零重力的角度调节。而为了解决,按摩椅靠背调节时,触及背后的器物或墙体,制造业者又想出了平躺前移式结构来。如专利申请号201220674433.1,公开一种前移式靠背可调座椅,包括有坐架和靠背架,其特征是还包括一底座,坐架通过轨道滑动定位在底座上,两者之间还设有驱动机构,借助该驱动机构驱动坐架前移或后退动作,所述底座两侧各设一条弧形滑槽,两条弧形滑槽相向且成对称结构;靠背架中下部通过销轴定位在坐架上,靠背架下端部两侧分别安装有滚轮,两滚轮分别落在两条弧形滑槽中,形成活动限位。本专利技术借助坐架带动靠背架前移的同时,联动靠背架后倾调节,达到不占后部空间的目的。但也存在不足,如坐架角度恒定,使得零重力效果不明显;坐架前端需设置着地脚轮,易造成地板的磨损,也增加不必要的阻力;两侧设 ...
