Embodiment 1, as shown in fig. 1 and 3, a chair with an adaptive lumbar support includes a seat 1, a backrest 2, a lumbar support 3, and an adaptive member 4. The waist support 3 is used for supporting the waist of a user, and the waist support 3 is connected with the chair back 2 through the self-adaptive piece 4. The adaptive part 4 comprises a first mounting plate 41, a second mounting plate 42 and an elastic part 43 for connecting the first mounting plate 41 and the second mounting plate 42, wherein the first mounting plate 41 is connected with the chair back 2, and the second mounting plate 42 is connected with the lumbar support 3.

The elastic part 43 in the adaptive piece 4 is arranged between the chair back 2 and the waist support 3, and when a user leans on the waist support 3, the elastic part 43 provides elastic force for the waist support 3 to cling to the user by using the elasticity of the user, so that the waist support 3 can be fitted with the waist of the user and provides a certain supporting force for the waist. The elastic part 43 can twist and move in all directions, that is, the lumbar support 3 can also twist in all directions, so that the lumbar support 3 can be driven to move synchronously when the waist of the user moves, and after the elastic part 43 moves, the elastic part continues to provide elastic force or torsion force in all directions for the lumbar support 3, so that the lumbar support 3 continues to wrap, fit the waist of the user and provide supporting force.

Self-adaptation piece 4 is connected with back of the chair 2, waist respectively through mounting panel one 41, mounting panel two 42, and the extension end extending direction of mounting panel one 41 and mounting panel two 42 is different each other not coincide, has left the installation space that does not coincide, makes things convenient for the later stage to connect back of the chair 2 and waist and leans on 3, and during the installation, can use the mounting to be connected, simple to operate like connecting pieces such as rifle nail, bolt. The chair back 2 and the waist support 3 are connected through the self-adaptive piece 4, on one hand, the self-adaptive piece is different from the situation that a plurality of self-adaptive pieces 4 are arranged on the waist support 3, and only one self-adaptive piece 4 provides supporting force for the waist support 3, so that the waist support 3 is more flexible in movement and can be adapted to the waist of a human body; on the other hand, the material is saved and the cost is reduced.

As shown in fig. 3, the elastic portion 43 includes a spring 431 and connecting plates 432 attached to both ends of the spring 431. In order to facilitate the connection of the elastic portion 43 with the first mounting plate 41 and the second mounting plate 42, each connecting plate 432 is provided with a plug 433, and the first mounting plate 41 and the second mounting plate 42 include a slot adapted to the plug 433. When in connection, the connection can be completed only by inserting the plug 433 into the slot, and the installation is convenient. In order to further enhance the connection strength between the elastic portion 43 and the first and second mounting

plates

41 and 42, the plug 433 is further provided with a fastening ridge 434, and after the plug 433 is plugged into the slot, the fastening ridge 434 is fastened with a fastening ridge groove in the slot, so that the plug 433 is not easily separated from the slot. In order to conveniently connect the spring 433 with the connecting plate 432, one side of the connecting plate 432 close to the spring 431 is provided with a plurality of fixing blocks 435 with holes, and the tail end of the spring 431 can be fixedly connected with the connecting plate 432 after sequentially penetrating through the holes of the plurality of fixing blocks 435, so that the connection is convenient and firm.

As shown in fig. 1-3, different users have different requirements for the height position of the lumbar support due to the difference in size of the users. The self-adaptive piece 4 in the embodiment can be detachably arranged at different height positions of the chair back 2 so as to conveniently adjust the height of the lumbar support 3. The leaning surface of the chair back 2 is provided with a connecting rod 21 extending in the height direction, a clamping buckle 5 is installed on the first mounting plate 41, the clamping buckle 5 is provided with an opening, and the clamping buckle 5 is connected with the connecting rod 21 in a buckling mode after the opening penetrates through the connecting rod 21. When the height of the waist rest 3 needs to be changed, the clamping buckle 5 only needs to be separated from the original position and is buckled to the connecting rod 21 at different height positions again, and the adjustment is convenient. The connecting rod 21 is a metal rod, and the clamping buckle 5 is a U-shaped pipe clamp with a U-shaped opening.

When the chair back 2 and the waist support 3 are connected, bolts or gun nails penetrate through the second mounting plate 42 and the waist support 3 and then are fixed; then the snap fastener 5 is fastened with the connecting rod 21. The connection between the chair back 2 and the lumbar support 3 is completed.

As shown in fig. 2, the fastening portion of the buckle 5 may be loosened after the buckle is connected to the connecting rod 21 for a long time, so that the buckle 5 may be displaced. In order to prevent the displacement of the snap fastener 5, the connecting rod 21 includes the snap-fit areas 211 and the supporting areas 212 arranged at intervals, and since the diameter of the snap-fit area 211 is smaller than that of the supporting areas 212, the snap fastener 5 is fastened with the snap-fit areas 211 and then limited between the adjacent supporting areas 212, so as to ensure that the snap fastener 5 cannot move downwards or upwards.

The clamping area 211 surface is equipped with the rubber layer, and the one side that the clamping is buckled 5 and is close to clamping area 211 is provided with the rubber layer, and the rubber layer has increased frictional force between them, further prevents that clamping is buckled 5 and is fallen from the clamping area 211 of connecting rod 21.

Embodiment 2, as shown in fig. 4 and 5, differs from embodiment 1 in that the adaptive element 4 only includes a first mounting plate 41, an elastic portion 42 and a second mounting plate 43, the first mounting plate 41 is directly connected to the seat back 2, the second mounting plate 43 is directly connected to the lumbar support 3, and the elastic portion 43 is a spring. The first mounting plate 41 and the second mounting plate 42 are triangular plates, mounting holes are formed in the top corners of the first mounting plate 41 and the second mounting plate 42, and the top corners of the first mounting plate 41 and the second mounting plate 42 do not coincide with each other in the horizontal direction. The first mounting plate 41 and the second mounting plate 42 are triangular plates, and the elastic part 43 is mounted in the middle of the triangular plates. The three apex angle of triangle-shaped board is equipped with the mounting hole, and the mounting hole supplies mounting such as bolt to pass, and three mounting hole has formed three fixed point, and later stage connection is more firm. The mounting plate I and the mounting plate II are not overlapped with each other at each vertex angle in the horizontal direction, a non-overlapped mounting space is reserved, and the chair back and the waist support can be conveniently connected at the later stage.
