The invention aims to provide a backup plate which can be better matched with the waist of a user in shape and can well support the waist, a backup plate body is made of a deformable material, the surface, corresponding to the waist of the user, of the backup plate body is a bearing surface, the bearing surface is a double-curved surface, and the double-curved surface is a double-curved surface. The longitudinal middle of the supporting surface protrudes towards the side of a user, the transverse middle of the supporting surface is sunken relative to the side of the user, when the waist of the user leans on the backup plate, the backup plate body is slightly elongated in the longitudinal direction, the two transverse sides of the backup plate body extend forwards, and in the state, the longitudinal curve of the supporting surface can be better matched with the physiological curve of the waist of the user; the supporting performance is improved; on the other hand, the two transverse side parts can also generate an enveloping feeling on the waist of the user, the use feeling is improved, and meanwhile the supporting performance can be further improved. The invention further provides a waist support comprising the backup plate.

    本发明的目的在于提供一种能够更好地与使用者的腰部形状相配合且能够对腰部形成良好支撑的靠板,其中,靠板本体采用可形变材料制成,靠板本体的与使用者的腰部相对应的表面为承托表面,该承托表面为双曲面,其纵向中部向使用者侧凸出,且横向中部相对于使用者侧凹陷,在使用者将腰部靠在靠板上时,靠板本体在纵向方向上略微伸长且横向两侧部分向前伸,这种状态下,承托表面在纵向上的曲线能够更好地与使用者的腰部生理曲线相适配,提高支撑性;另一方面,横向两侧部分也能够对使用者的腰部产生包络感,提升使用感受的同时也能够进一步提高支撑性。本发明还提供了含有该靠板的腰托。
