Technical Field

[0001] The utility model relates to the technical field of furniture, and particularly relates to a seat backrest. Background Art

[0002] In recent years, with the development of the social economy and the acceleration of people's living rhythm, more and more people are running around for study and work, resulting in more and more people becoming sedentary. Therefore, whether a chair is safe and comfortable has become the primary requirement for people to select a chair.

[0003] When the lumbar support in the existing chair supports the waist of the user, the lumbar support of the waist can only singlely abut against a single area of the waist, and it is very difficult to achieve a complete circumferential leaning against the entire waist of the user. Moreover, due to the differences among users, the height positions of the waists of adult men and adult women are also different, which easily causes usage defects. Summary of the Utility Model

[0004] The purpose of the utility model is to overcome the deficiencies of the prior art and propose a seat backrest, which is used to solve the technical problems that the lumbar support of the waist can only singlely abut against a single area of the waist, and it is very difficult to achieve a complete circumferential leaning against the entire waist of the user. Moreover, due to the differences among users, the height positions of the waists of adult men and adult women are also different, which easily causes usage defects.

[0005] To achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A seat backrest includes a lumbar support and a backrest. The lumbar support is buckled on the backrest. A row of vertical female buckles are arranged on both sides of the backrest. One piece of cotton cloth is arranged on each side of the lumbar support, and two vertically distributed male buckles are arranged on both pieces of cotton cloth. The male buckles on both pieces of cotton cloth can be respectively buckled with the female buckles on both sides of the backrest. One elastic band is also arranged on each side of the lumbar support, and a lumbar support belt is arranged on each elastic band, and the two lumbar support belts are detachably connected.

[0007] Working Principle:

[0008] When the user leans on the backrest, due to the differences among users, the abutting positions of the lumbar support against the back are different. At this time, when the user leans on the backrest, the waist also abuts against the lumbar support at the same time. Then, the lumbar support belts on both sides of the lumbar support are attached to each other, which can fit the waist of the user with the lumbar support, prevent the user from having a displacement of the waist posture when leaning on the seat for a long time, resulting in diseases harmful to health such as lumbar disc herniation. And the cotton cloth on both sides of the lumbar support can be pulled until the male buckles on both sides of the cotton cloth are pulled out from the female buckles on both sides of the backrest. Then, the male buckles on both sides are re-buckled to the female buckles on both sides of the backrest suitable for the user.

[0009] The beneficial effects of the present utility model are as follows:

[0010] Compared with some existing technologies, most lumbar supports are fixedly installed on the backrest. However, in this application document, the cotton cloth on both sides of the lumbar support can be pulled until the sub - buttons on both sides of the cotton cloth are pulled out from the mother - buttons on both sides of the backrest, and then the two sub - buttons can be re - buckled to the mother - buttons on both sides of the backrest suitable for the user, so that the overall height of the lumbar support can be adjusted and it can be adapted to the usage situation of the user.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0013] The technical solutions in the present utility model will be further described below with reference to the drawings and embodiments.

[0014] As Figure 1 shown, a seat backrest includes a lumbar support 1 and a backrest 2. The lumbar support 1 is buckled to the backrest 2. A row of vertical mother - buttons 3 are provided on both sides of the backrest 2. A piece of cotton cloth 4 is provided on each side of the lumbar support 1, and two vertically - distributed sub - buttons 5 are provided on each of the two pieces of cotton cloth 4. The sub - buttons 5 on the two pieces of cotton cloth 4 can be respectively buckled with the mother - buttons 3 on both sides of the backrest 2. An elastic band 6 is further provided on each side of the lumbar support 1, and a lumbar belt 7 is provided on each elastic band 6, and the two lumbar belts 7 are detachably connected.

[0015] When a user leans on the backrest 2, due to the differences among users, the contact position of the lumbar support 1 with the back is different. At this time, when the user leans on the backrest 2, the waist simultaneously abuts against the lumbar support 1. Then, the lumbar belts 7 on both sides of the lumbar support 1 are adhered to each other, which can fit the user's waist with the lumbar support 1. And the cotton cloth 4 on both sides of the lumbar support 1 can be pulled until the sub - buttons 5 on both sides of the cotton cloth 4 are pulled out from the mother - buttons 3 on both sides of the backrest 2, and then the two sub - buttons 5 are re - buckled to the mother - buttons 3 on both sides of the backrest 2 suitable for the user.

[0016] As Figure 1As shown, the lumbar support 1 includes a first block 13, a second block 14, and a connecting cloth 15. The second block 14 is disposed on one side of the first block 13, and the connecting cloth 15 is disposed between the first block 13 and the second block 14 and is used to connect the first block 13 and the second block 14. The first block 13 and the second block 14 are respectively composed of a high-resilience sponge block 8 and a wrapping cloth 9, and the wrapping cloth 9 is sleeved on the outer surface of the high-resilience sponge block 8.

[0017] When the waist width spacing of the user is relatively small, the user squeezes the first block 13 and the second block 14 against each other, places the connecting cloth 15 located between the first block 13 and the second block 14 in the middle and the connecting cloth 15 will not protrude to one side of the user, causing discomfort to the user. When the waist width spacing of the user is relatively large, the user only needs to pull the first block 13 and the second block 14 away from each other until the connecting cloth 15 is tightened. At this time, when the user's waist leans on the lumbar support 1, a certain spacing can be enlarged, making the user feel relatively comfortable. And the high-resilience sponge block 8 provided can make the user more comfortable when leaning.

[0018] As Figure 1 shown, a plurality of through holes 10 for ventilation are formed in the wrapping cloth 9. The side of the lumbar support 1 close to the user is set as a curved surface, and further includes two extension blocks 17. The two extension blocks 17 are respectively disposed on both sides of the lumbar support 1 and the end faces of the two extension blocks are attached to the user's waist. The two waist belts 7 are respectively provided with a hook surface 11 and a loop surface 12 of Velcro, and the two waist belts 7 are adhesively connected to each other. An opening 16 is formed in each of the two waist belts 7, and a heat patch can be adhesively attached in the opening 16.

[0019] The through holes 10 provided can make the user more breathable when using, and the gradually widening lumbar support 1 can also make the user more comfortable when leaning. And the mutual cooperation of the hook surface and the loop surface 12 of Velcro on the waist belt 7 can firmly fix the user's waist and the lumbar support 1 together, making it more comfortable when leaning. And the opening provided on the waist belt 7 can adhesively attach a heat patch, so that the user's waist and stomach will not catch a cold.

[0020] Working principle:

[0021] When the user leans on the backrest 2, due to the differences among users, the contact positions of the lumbar support 1 with the back are different. At this time, when the user leans on the backrest 2, the waist simultaneously contacts the lumbar support 1. Then, the waist belts 7 on both sides of the lumbar support 1 are adhered to each other, which can fit the user's waist with the lumbar support 1, preventing diseases that are harmful to health such as lumbar disc herniation caused by the displacement of the waist posture when the user leans on the seat for a long time. And the cotton cloth 4 on both sides of the lumbar support 1 can be pulled until the male buttons 5 on both sides of the cotton cloth 4 are pulled out from the female buttons 3 on both sides of the backrest 2. Then, the male buttons 5 on both sides are re-fastened to the female buttons 3 on both sides of the backrest 2 suitable for the user. In this way, different distance positions can be changed according to the physical conditions of different users, increasing the applicable range of this lumbar support 1. Then, when the two lumbar pads are reversely wound and attached to the backrest 2, the lumbar support 1 can be more firmly fixed on the backrest 2.

[0022] When the waist width interval of the user is relatively small, at this time, the user squeezes the first block 13 and the second block 14 together, places the connecting cloth 15 between the first block 13 and the second block 14 in the middle and the connecting cloth 15 will not protrude to one side of the user, causing discomfort to the user. When the waist width interval of the user is relatively large, the user only needs to pull the first block 13 and the second block 14 apart until the connecting cloth 15 is tightened. At this time, when the user's waist leans on the lumbar support 1, a certain interval can be enlarged, making the user feel more comfortable. And the high-resilience sponge block 8 provided can make the user more comfortable when leaning. The through holes 10 provided can make the user more breathable when using. And the gradually widening lumbar support 1 can also make the user more comfortable when leaning. And the mutual cooperation of the hook surface and the loop surface 12 of the magic tape on the waist belt 7 can fix the user's waist and the lumbar support 1 firmly together, making it more comfortable when leaning. And by setting an opening on the waist belt 7, a heat patch can be adhered, so that the user's waist and stomach will not catch cold.
