Problems solved by technology

[0002] At present, swivel chairs are generally equipped with a lumbar pad for supporting the waist, but most of the lumbar pads are fixed, and even if they are movable, they can only swing slightly. When sitting on a swivel chair or in different sitting postures, the position of the waist is not the same, so the adjustment of the lumbar cushion requires a wide range of adjustments to suit the needs of people of different body types

no. 1 example

[0030] The first embodiment: as Figure 1 to Figure 4 Shown, a kind of chair with retractable lumbar cushion comprises by chair back 1, chair pad 2 and chair foot 3, it is characterized in that, be provided with installation space 4 between described chair back 1 and chair pad 2, install The space 4 is provided with an inclined sleeve 5, and the inclined sleeve 5 is telescopically connected with a waist pad 6 through a telescopic assembly.

[0031] The chair back 1 and the seat cushion 2 can be arranged as a split type, or as a connected body, but the installation space 4 must be left in both ways.

[0032] With the lumbar pad adjustment structure of this structure, the lumbar pad 6 can be telescopically adjusted along the tilting sleeve 5 to realize the tilting telescopic adjustment of the lumbar pad 6, which is suitable for people of different body types. During the stretching process of the pad 6, the height adjustment is realized, which makes the adjustment more flexible....

no. 2 example

[0036] The second embodiment: as Figure 5 As shown, it is similar to the first embodiment, except that: the first driver 10 is an electric driver; in an electric form, by setting an electronic switch, the electric driver such as a motor, a cylinder and other electronic drive equipment drives the transverse link 14 rotations to realize the telescopic adjustment of the waist pad 6, which can also achieve the adjustment function, and avoid the cumbersome manual operation.

no. 3 example

[0037] The third embodiment: as Figure 5 As shown, similar to the first and second embodiments, the difference is that in addition to the telescopic function of the waist pad 6, the swing function of the waist pad 6 is also added, specifically: the other side of the transverse sleeve 9 is internally connected There is a latch 18, and the latch 18 is connected with a second driver 20 through a reduction box 19; in order to increase the adjustment angle of the lumbar pad 6, the rotation of the transverse sleeve 9 is realized by the second driver 20, and the rotation of the transverse sleeve 9 makes it connected to the transverse sleeve. The inclined sleeve 5 of the barrel 9 rotates around the central axis of the transverse sleeve 9, finally realizing the swing of the waist pad 6, increasing the adjustment angle of the waist pad 6, so that the waist pad 6 can not only realize stretching, but also swing, further It is suitable for the requirements of different body shapes and dif...

Abstract

The invention relates to a chair with a telescopic lumbar cushion. The chair comprises a chair back, a chair cushion and chair legs, wherein an inclined sleeve is obliquely arranged on the chair back or the chair cushion or between the chair back and the chair cushion; the lumbar cushion is connected onto the inclined sleeve in a telescopic manner through a telescopic component; with the adoption of a lumbar cushion regulating structure, the lumbar cushion can be regulated along the inclined sleeve in a telescopic manner, the inclined telescopic regulation of the lumbar cushion can be realized, so that the chair is suitable for being used by people with different bodily forms; the inclined sleeve is obliquely arranged, so that the height can be regulated during the expansion and contraction of the lumbar cushion, and the regulation is more flexible.

Description

technical field [0001] The invention relates to the technical field of chairs, in particular to a chair with a retractable lumbar cushion. Background technique [0002] At present, swivel chairs are generally equipped with a lumbar pad for supporting the waist, but most of the lumbar pads are fixed, and even if they are movable, they can only swing slightly. When sitting on a swivel chair, or in different sitting postures, the position of the waist is not the same, so the adjustment of the lumbar cushion requires a wide range of adjustments to meet the needs of people of different shapes. Contents of the invention [0003] The purpose of the present invention is to solve the above-mentioned deficiencies in the prior art, and improve a chair with a telescopic lumbar pad that is simple and reasonable in structure, easy to adjust, large in adjustment angle, low in manufacturing cost, and suitable for people of different body types. [0004] The technical solution adopted by ...
