The purpose of the present invention is to provide a curvature adjusting mechanism for a waist support, the curvature of a backup plate being variable so as to fit the curvature of the waist of different users, the curvature adjusting mechanism comprising: a base plate, one end of which is connected to one end of the backup plate; the other end of the backup plate can slide relative to the base plate, and the range limiting piece is used for limiting the other end of the backup plate within different sliding ranges, so that the distance change range of the other end of the backup plate relative to one end of the backup plate is changed, and the curvature change range of the backup plate is adjusted. The invention further provides an adjustable waist support comprising the curvature adjusting mechanism.

    本发明的目的在于提供一种靠板曲度可变从而能够配合不同使用者的腰部曲度的腰托曲度调节机构,该曲度调节机构包括:基板,一端与靠板的一端连接;范围限制件,其中,靠板的另一端相对于基板可滑动,范围限制件用于将靠板的另一端限制在不同的可滑动范围内,从而改变靠板的另一端相对于靠板的一端的距离变化范围,实现靠板的曲度变化范围的调节。本发明还提供了含有该曲度调节机构的可调式腰托。
