Embodiment 1

[0042] Such as figure 1 As shown, the present embodiment designs an adaptive waist-hip cushion structure, including buttock support plate 2, waist support plate 4, rotation pivot 3 and rear support member 5 and other structures.

[0043] The waist-hip cushion structure can be placed on the seat 1 , or connected to the seat 1 in a detachable manner, or designed integrally with the seat 1 as a part of the seat 1 .

[0044] The seat 1 in the present embodiment includes a seat plate 11, an elastic connector 12 and a back plate 13; the seat plate 11 is used for sitting and standing of the human body, and the back plate 13 is connected to the rear side of the seat plate 11 by the elastic connector 12, The backboard 13 is inclined or upright.

[0045] The buttock supporting plate 2 mentioned above can support the buttocks of the human body correspondingly, and the buttock supporting plate 2 is mainly held up in the area where the rear side is not in contact with the seat plate 11, t...

Embodiment 2

[0052] Such as Figure 1-4 As shown, on the basis of the structure of Embodiment 1, in order to solve the comfort problem of the waist-hip cushion structure, this embodiment adopts the following structural design:

[0053] The buttock supporting board 2 is designed to be arc-shaped or an arc-shaped buttock arc supporting part 22 is arranged on the hip supporting board 2, and the buttock arc supporting part 22 is arched or sunken toward the side of the human body sitting and standing direction. Utilize the self-elasticity of the arched or sunken buttock support plate 2 to further fit the rear side of the human buttocks, thereby improving the support comfort of the buttocks area.

[0054] In addition, the buttock cushion 21 can also be laid on the surface of the buttock support plate 2 facing the human body; Contact comfort.

[0055] The comfort of the buttocks supporting plate 2 can also be realized by arranging reinforcing ribs, and the buttocks reinforcing ribs 23 can be ar...

Embodiment 3

[0060] Such as figure 1 , 5 As shown in -8, on the basis of the structure of Embodiment 1, in order to solve the problem that the position of the rotation pivot 3 of the waist-hip cushion structure can be adjusted vertically, so as to improve the adaptability between the waist-hip cushion and the waist-hip of the human body during the pitching process of the human body, this implementation Example Structural design of the rear support 5, the rear support 5 includes a support body 52 and a support connector 51, the support connector 51 is fixed on the support body 52, and a pivot connection position 55 is arranged on the support connector 51 , the pivotal connection position 55 is used for rotating the pivotal connection of the pivot 3; at the same time, the supporting body 52 may include an airbag-type design and a spring-type design.

[0061] Such as Figure 5 , 6 As shown in the airbag design, the supporting body 52 is in a cylindrical, elliptical, or triangular column-sh...

Abstract

The invention belongs to the technical field of waist rests or waist cushions, and particularly relates to a self-adaptive waist-hip back cushion structure, which comprises a hip supporting plate, a waist backup plate, a rotating pivot and a rear supporting piece, the rotating pivot is connected to the intersection of the hip supporting plate and the waist backup plate, and the rotating pivot is as high as the hip joint of a human body in a sitting posture. The hip supporting plate and the waist backup plate form a lever by taking the rotating pivot as a fulcrum; the rotating pivot is rotatably connected with the rear supporting piece, and the rear supporting piece is used for supporting the rotating pivot to be arranged at a set height position; according to the scheme, the hip and the waist of a human body can be synchronously supported, and the supporting pressure borne by hip joints is effectively reduced; due to the lever type linkage relation between the hip supporting plate and the waist backup plate, the comfort of the human body in the pitching process is guaranteed; the rotating pivot not only can provide rotating support, but also ensures comfort and self-adaptability of waist and hip support in the scheme by means of the supporting main body in an air bag type design or a spring type design according to the height of the rotating pivot.

Description

technical field [0001] The invention belongs to the technical field of lumbar support or lumbar cushion, and in particular relates to an adaptive waist-hip cushion structure. Background technique [0002] As one of the essential articles for people's daily life, the chair is an important rest appliance that provides the weight of the human body when the human body is at home, office, or reading, and brings convenience to people's rest and office. The buttocks are supported, and the legs can be temporarily relieved because of the support. There are also common chairs with a backrest, which can also make the human body's back lean; however, the lumbar spine problems caused by sitting for a long time And sub-health has always been a life issue that people pay attention to. [0003] The shape of the human body is wide chest and back, wide hips, and narrow waist. When the human body is lying flat, the upward supporting force of the human trunk is mainly divided into three parts:...
