The invention discloses a supporting and mounting structure of a seat waist support, which comprises a waist support fixing plate, a waist support sliding plate, a driving mechanism and a torsional spring supporting mechanism, and is characterized in that the driving mechanism is mounted on the waist support fixing plate; the driving end of the driving mechanism is connected to the waist support sliding plate; a first torsion end and a second torsion end are arranged on the two opposite sides of the torsion spring supporting mechanism correspondingly. A first torsion end of the torsion spring supporting mechanism is connected to the waist support fixing plate; a second torsion end of the torsion spring supporting mechanism is connected to the waist support sliding plate; the supporting end of the torsional spring supporting mechanism is used for supporting a seat waist support; the waist support fixing plate and the waist support sliding plate are driven by the driving mechanism to slide relatively, so that the torsional spring supporting mechanism is supported and falls back, and the waist support adjusting function is achieved; the two ends of the torsion spring supporting mechanism are in torsion connection with the waist support fixing plate and the waist support sliding plate respectively, so that the problem of abnormal sound caused by elasticity loss of an elastic steel sheet is solved.
本发明公开了一种座椅腰托的支撑安装结构,包括腰托固定板、腰托滑动板、驱动机构和扭簧支撑机构,其中:驱动机构安装在腰托固定板上;驱动机构的驱动端连接于腰托滑动板;扭簧支撑机构的对向两侧分别设置有第一扭力端和第二扭力端;扭簧支撑机构的第一扭力端连接于腰托固定板;扭簧支撑机构的第二扭力端连接于腰托滑动板;扭簧支撑机构的支撑端用于支撑座椅腰托;通过驱动机构驱动腰托固定板与腰托滑动板相对滑动,使扭簧支撑机构支起和回落,实现腰托调节功能;通过扭簧支撑机构两端分别与腰托固定板和腰托滑动板扭力连接,消除弹性钢片存在的弹性损失导致的异响问题。
