Four-direction waist support driven by inhaul cable traction
Four-direction waist support driven by inhaul cable traction
The invention discloses a four-direction waist support driven by inhaul cable traction. The support comprises a supporting assembly located in a backrest frame body, the upper end of the supporting assembly is in running fit with the backrest frame body, and the supporting assembly comprises a supporting body and a Z-direction driving mechanism for driving the supporting body to move in the height direction of the backrest frame body; the waist support also comprises an X-direction driving mechanism which comprises an inhaul cable and an inhaul cable motor for controlling the inhaul cable to move, wherein the inhaul cable is supported at the lower end of the rear side of the supporting assembly, and the inhaul cable motor can work to drive the supporting assembly to move in the thickness direction of the backrest frame body; and the waist support also comprises a first tension spring and a second tension spring which are connected to the two ends of the backrest frame body respectively, and the ends, away from the backrest frame body, of the first tension spring and the second tension spring are connected to the inhaul cable. The waist support has the advantages that the supporting assembly can adaptively float along with thrust or self weight of the back of the human body, elastic support is formed, and compared with a traditional waist support, the comfort is better.
本发明公开了一种拉索牵引驱动的四向腰托，包括位于靠背框体内部的支撑组件，支撑组件上端与靠背框体转动配合，支撑组件包括支撑体以及驱动支撑体沿靠背框体高度方向移动的Z向驱动机构；X向驱动机构，其包括拉索和控制该拉索运动的拉索电机，其中，所述拉索支撑在所述支撑组件的后侧下端，所述拉索电机工作能够驱动支撑组件的沿靠背框体厚度方向移动；以及分别连接在所述靠背框体两端的第一拉簧和第二拉簧，所述第一拉簧和第二拉簧远离靠背框体的一端均连接在所述拉索上。本发明的有益效果是：支撑组件能够随人体背部的推力或自重进行适应性浮动，并形成一种弹性支撑，相对于传统的腰托而言，舒适性更好。
