The invention discloses a back cushion thickness-width linkage adjusting mechanism which comprises a cushion body, the cushion body comprises two face plates arranged oppositely, a compression guide mechanism is connected between the two face plates, and the two face plates are restrained by the compression guide mechanism to be close to or far away from each other; a thickness resetting piece is further arranged between the two panels and drives the two panels to be far away from each other; two expansion wing plates are further arranged on the outer side of any panel, distributed in the left-right direction of the pad body, assembled with the pad body in a sliding mode in the left-right direction of the pad body, connected with the guide body and synchronously linked with the guide body. The seat cushion has the remarkable effects that when the cushion body used as a backrest is subjected to leaning pressure of a passenger, the thickness of the cushion body can be automatically compressed, and the supporting area of the cushion body can be synchronously expanded, so that extremely convenient use experience is provided for the user.

    本发明公开了一种靠垫厚度‑宽度联动调节机构,包括垫本体,该垫本体包括两块正对设置的面板,两块面板之间连接有压缩导向机构,两块面板受压缩导向机构的约束而相对靠近或远离;两块面板之间还设有厚度复位件,该厚度复位件带动两块面板相互远离;在任一面板的外侧还设有两块拓展翼板,两块拓展翼板沿垫本体的左右方向分布,两块拓展翼板分别沿垫本体的左右方向与其滑动装配,两块拓展翼板分别与导向主体连接并与其同步联动。采用本发明的显著效果是,作为靠背功能使用的垫本体能在受到乘客倚靠压力时,自动压缩其厚度、并同步扩展其支撑面积,从而为用户提供极致便捷的使用体验。
