a waist rest is characterized in that: the human body curve-conforming wavy support plate is included, a plurality of wedge-shaped components which are hinged together are arranged on the front side of the support plate, and the wedge-shaped components at the uppermost end and the lowermost end are respectively hinged with the support plate; the wedge-shaped members comprise groove bodies, the cross sections of the groove bodies are trapezoidal, the groove bodies are formed by side walls with different heights, the two side walls are parallel, two hinge lug plates are respectively arranged on the upper portion and the lower portion of each groove body, every two adjacent wedge-shaped members are hinged together through the hinge lug plates, and elastic elements are arranged between every two adjacent wedge-shaped members and on one side, facing the supporting plate, of each wedge-shaped member; among all the wedge-shaped components, the side wall facing one side of the supporting plate is divided into a high side wall group and a low side wall group, the high side wall group and the low side wall group are respectively composed of at least one wedge-shaped component, the high side wall group and the low side wall group are arranged at intervals to form a curve conforming to the curve of a human body, and a waist backing plate is fixedly arranged on one side of each wedge-shaped component facing the human body.
Two connecting pieces are arranged on the supporting plate, and the wedge-shaped components at the upper end and the lower end are respectively hinged with the two connecting pieces.
The supporting plate is provided with a through groove, and the connecting piece is fixed on the supporting plate through a screw penetrating through the through groove.
The lower end of the supporting plate is connected with the cushion through a leaf spring.
The leaf spring is fixed to the support plate by another bolt passing through the through groove.
The elastic element is a spring, a spring piece or elastic silica gel.
The number of the wedge-shaped components is 16, and the wedge-shaped components are sequentially from top to bottom: the high-strength concrete wall comprises a low side wall group consisting of two wedge-shaped members, a high side wall group consisting of one wedge-shaped member, a low side wall group consisting of one wedge-shaped member, a high side wall group consisting of four wedge-shaped members and a low side wall group consisting of five wedge-shaped members.
The invention has the beneficial effects that:

In the figure, 1 supporting plate, 2 connecting pieces, 3 cushion, 4 leaf spring, 5 elastic elements, 6 wedge-shaped members, 600 groove bodies, 601 side walls, 602 hinged lug plates, 603 reinforcing plates, 7 waist backing plates and 8 through grooves.
Detailed Description
The drawings illustrate specific embodiments of the invention. As shown in fig. 1 to 11, the waist rest comprises a support plate 1, wherein the support plate 1 is a wavy support plate 1 conforming to the curve of a human body, of course, only one surface facing the human body is wavy, four through grooves 8 are formed in the support plate 1, the through grooves 8 are long-strip-shaped, the upper end and the lower end of each through groove are respectively provided with a screw, the through grooves 8 at the lower end of each through groove are respectively provided with two screws, each through groove 8 is provided with a screw penetrating through the through groove 8 from the back surface of the support plate 1 and then connected with a connecting piece 2 in a threaded manner, that is, the position of the connecting piece 2 in each through groove 8 can be adjusted up and down, a plurality of wedge-shaped members 6 hinged together are arranged between the two connecting pieces 2, 16 wedge-shaped members 6 are arranged at the front side of the support plate 1, and the requirements of different heights can be met by adjusting the positions of the connecting pieces 2; the lower extreme of backup pad 1 is connected with cushion 3 through a leaf spring 4, and wherein, the lower extreme and the 3 fixed connection of cushion of leaf spring 4, the upper end is the same with connecting piece 2, passes through threaded connection behind the logical groove 8 through two screws to fix in the backup pad, its fixed position also can reciprocate.
The wedge-shaped member 6 is a groove body 600 which is reversely buckled, the front side wall 601 and the rear side wall 601 of the groove body 600 are parallel to each other and have a long side and a short side, that is, the cross section of the groove body 600 is trapezoidal, two hinge lug plates 602 are respectively arranged at the upper part and the lower part of the wedge-shaped member 6, the two hinge lug plates 602 are respectively arranged at two ends of the groove body 600, the two adjacent wedge-shaped members 6 are hinged together through the hinge lug plates 602, the wedge-shaped member 6 at the uppermost end is hinged with the connecting piece 2 at the upper part, and the wedge-shaped member 6 at the lowermost end is hinged with the connecting piece 2 at the lower part; elastic elements 5 are fixedly arranged between two adjacent wedge-shaped members 6 and on the side of the wedge-shaped members 6 facing the support plate 1, the elastic elements 5 are preferably located at the middle position in the length direction, and the elastic elements 5 can be springs, spring pieces or elastic silica gel and the like.
In order to increase the strength, the reinforcing plate 603 is installed between the two side walls 601, and may be one or two, and if the two side walls are provided, the two side walls may be arranged in a crossed manner, and the crossing may be realized by plastic injection molding or 3D printing.
The wedge-shaped members 6 are not arranged in one orientation, and are connected according to the size of the wedge-shaped members 6 and the shape of the human body curve, wherein the side walls of the short sides face the support plate 1, the side walls of the long sides face the support plate 1, and the wedge-shaped members 6 are arranged at intervals, the number of the wedge-shaped members 6 in the same orientation in each interval can be the same, or can be different, so as to form the curve conforming to the human body curve, and 16 wedge-shaped members 6 in the embodiment are taken as an example:
we call the adjacent wedge-shaped members 6 of the same orientation a high side wall group and a low side wall group respectively, the high side wall group means that the long side wall faces the support plate 1, the low side wall group means that the short side wall faces the support plate 1, and the distribution from top to bottom is as follows: a short set of side walls consisting of two wedge-shaped members 6, a high set of side walls consisting of one wedge-shaped member 6, a short set of side walls consisting of one wedge-shaped member 6, a high set of side walls consisting of four wedge-shaped members 6, a short set of side walls consisting of five wedge-shaped members 6.
On the side of each wedge-shaped member 6 facing the user, a lumbar plate 7 is mounted.
Since the adjacent wedge members 6 are hinged together by the hinge ear plates 602, when pressed by the human body, they automatically deform to form a curve that conforms to the human body curve, dynamically supporting and protecting the back and waist of the user according to the sitting posture of the user.
Other technical features than those described in the specification are known to those skilled in the art.
