Technical Field
[0001] This utility model relates to the field of office chair technology, specifically to an office chair with lumbar support to relieve fatigue. Background Technology
[0002] Currently, office chairs are chairs designed and manufactured specifically for the needs of seated work in daily work and social activities. Their main function is to provide users with a comfortable, supportive, and ergonomic sitting environment to improve work efficiency, reduce physical stress caused by prolonged sitting, and ensure the health and comfort of users.
[0003] Office chairs are used in office spaces. When working, office workers need to concentrate for long periods of time, which keeps them in a state of tension, leading to physical pain, especially discomfort in the lower back due to pressure. Most existing office chairs are relatively traditional and do not have good lumbar pressure relief functions, making it easy for office workers to experience lower back pain due to prolonged sitting, thus affecting their comfort and work efficiency.
[0004] Therefore, we propose a lumbar support office chair that can stretch and relax the user's lower back, effectively relieving fatigue. Utility Model Content
[0005] The purpose of this invention is to provide a lumbar support office chair that relieves fatigue, thus solving the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a lumbar support office chair for relieving fatigue, comprising chair legs, rubber pads fixedly installed on the outer bottom of each chair leg, a cylinder fixedly installed on the top of each chair leg, a seat cushion fixedly installed on the top of the cylinder, an elastic frame fixedly installed at one end of the bottom of the seat cushion, a backrest fixedly installed at the other end of the elastic frame, and a lumbar support mechanism installed between the seat cushion and the backrest.
[0007] The lumbar support mechanism includes a lumbar cushion installed between the seat cushion and the backrest, a cavity opened in the middle of the lumbar cushion, a pad fixedly installed on one side inside the cavity, an air pipe connected to one end of the cavity, and an air pump connected to the other end of the air pipe.
[0008] Optionally, the bottom and sidewalls of the lumbar cushion are respectively attached to the seat cushion and the sidewalls of the backrest, and the air pump is installed on the sidewalls of the backrest.
[0009] Optionally, a mounting component is fixedly installed on one side of the air pump, and the mounting component is fixedly installed on the side wall of the backrest by bolts. A wire is fixedly installed on one end of the air pump.
[0010] By adopting the above technical solution, it is easy to install the air pump on the backrest.
[0011] Optionally, a damping sleeve is rotatably mounted at the bottom of the cylinder, and a foot limiting mechanism is mounted on the damping sleeve.
[0012] Optionally, the foot limiting mechanism includes a bracket fixedly installed on the side wall of the damping sleeve, a support plate fixedly installed at the other end of the bracket, and a sponge pad fixedly installed at the other end of the support plate, wherein the support plate and the sponge pad are inclined upward.
[0013] By adopting the above technical solution, the user's legs can be restricted.
[0014] Optionally, the damping sleeve has a threaded hole on its side wall, and a bolt is installed in the threaded hole, with the other end of the bolt corresponding to the side wall of the cylinder.
[0015] By adopting the above technical solution, the damping sleeve can be positioned.
[0016] Compared with the prior art, the beneficial effects of the technical solution of this application are as follows:
[0017] The technical solution of this application uses an elastic frame installed at the bottom of the seat cushion and backrest to provide a certain cushioning effect. When the backrest is subjected to pressure, it tilts downward. While the user is leaning against the backrest to relieve fatigue, the lumbar support and pad installed between the seat cushion and backrest can support the user's waist, allowing the user's waist to be supported in an arch shape on the lumbar support. The user can pull the lumbar support to achieve a good effect in relieving fatigue. The user can simultaneously drive the air pump to inflate and deflate the cavity inside the lumbar support, allowing the lumbar support to expand and contract, thus ensuring that the lumbar support can relieve fatigue for users of different body types.
[0018] A damping sleeve is installed at the bottom of the cylinder, and a foot limiting mechanism is installed on the damping sleeve. When the user's back is against the backrest, the user's legs will slide down the seat cushion because there is no foot limit. At the same time, the user rotates the damping sleeve to move the support plate and sponge pad on the bracket to the front of the seat cushion. The user then kneels on the support plate and sponge pad with their feet together, ensuring that the user's legs are firmly limited. As the user continues to lean towards the backrest, the user's waist receives a better stretching effect, which further improves the fatigue relief effect. Attached Figure Description

[0023] Please see Figure 1-2 This utility model provides a technical solution: a lumbar support office chair for relieving fatigue, including a chair leg 1, with rubber pads 11 fixedly installed on the outer side of the bottom of the chair leg 1, a cylinder 12 fixedly installed on the top of the chair leg 1, a seat cushion 13 fixedly installed on the top of the cylinder 12, an elastic frame 14 fixedly installed at one end of the bottom of the seat cushion 13, a backrest 15 fixedly installed at the other end of the elastic frame 14, and a lumbar support mechanism installed between the seat cushion 13 and the backrest 15.
[0024] The lumbar support mechanism includes a lumbar cushion 2 installed between the seat cushion 13 and the backrest 15, a cavity 21 opened in the middle of the lumbar cushion 2, a pad block 22 fixedly installed on one side inside the cavity 21, an air pipe 23 connected to one end of the cavity 21, and an air pump 24 connected to the other end of the air pipe 23. The bottom and side wall of the lumbar cushion 2 are respectively in contact with the side wall of the seat cushion 13 and the backrest 15, and the air pump 24 is installed on the side wall of the backrest 15.
[0025] The elastic frame 14 installed at the bottom of the seat cushion 13 and the backrest 15 can provide a certain cushioning effect. When the backrest 15 is subjected to pressure, it tilts downward. At the same time, when the user leans against the backrest 15 to relieve fatigue, the lumbar pad 2 and the pad block 22 installed between the seat cushion 13 and the backrest 15 can support the user's waist, so that the user's waist is supported in an arch shape on the lumbar pad 2. The user's waist is pulled by the rope, thereby achieving a good relief of fatigue. The user can simultaneously drive the air pump 24 to inflate and deflate the cavity 21 inside the lumbar pad 2, so that the lumbar pad 2 can expand and shrink, thereby ensuring that the lumbar pad 2 can relieve the fatigue of the waist of users of different body types.
[0026] In this technical solution, a damping sleeve 32 is rotatably mounted on the bottom of the cylinder 12. A foot limiting mechanism is mounted on the damping sleeve 32. The foot limiting mechanism includes a bracket 33 fixedly mounted on the side wall of the damping sleeve 32, a support plate 34 fixedly mounted on the other end of the bracket 33, and a sponge pad 35 fixedly mounted on the other end of the support plate 34. The support plate 34 and the sponge pad 35 are inclined upwards, which can limit the user's legs.
[0027] When the user's back is against the backrest 15, the user's legs are not restrained, causing the user to slide down the seat cushion 13. At the same time, the user rotates the damping sleeve 32 to move the support plate 34 and sponge pad 35 on the bracket 33 to the front of the seat cushion 13. The user then kneels on the support plate 34 and sponge pad 35 with their feet together, ensuring that the user's legs are firmly restrained. As the user continues to lean towards the backrest 15, the user's waist receives a better stretching effect, further improving the fatigue relief effect.
[0028] In this technical solution, the side wall of the damping sleeve 32 is provided with a screw hole 36, and a bolt is installed in the internal thread of the screw hole 36. The other end of the bolt corresponds to the side wall of the cylinder 12, which can position the damping sleeve 32.
[0029] By tightening the bolt inside the screw hole 36, the other end of the bolt can be made to fit against the side wall of the cylinder 12, thereby positioning the damping sleeve 32 and ensuring the stability and firmness of the bracket 33, the support plate 34, and the sponge pad 35.
[0030] In this technical solution, an installation component 3 is fixedly installed on one side of the air pump 24. The installation component 3 is fixedly installed on the side wall of the backrest 15 by bolts.

[0032] In use, after the user sits on the seat cushion 13, the elastic frame 14 installed at the bottom of the seat cushion 13 and backrest 15 provides a certain cushioning effect. The backrest 15 tilts downwards under pressure, allowing the user to lean against it to relieve fatigue. Simultaneously, the lumbar support 2 and pad 22 installed between the seat cushion 13 and backrest 15 provide lumbar support, allowing the user's lower back to arch and be supported by the lumbar support 2. The lumbar support is then pulled along, effectively relieving fatigue. Simultaneously, the user drives the air pump 24 to inflate and deflate the cavity 21 inside the lumbar support 2, allowing it to expand and contract, thus ensuring the lumbar support 2 does not... The system relieves lumbar fatigue for users of similar body types. A damping sleeve 32 is mounted on the bottom of cylinder 12, and a foot restraint mechanism is installed on the damping sleeve 32. When the user's back rests against the backrest 15, the user's legs are not restrained, causing the user to slide down the seat cushion 13. Simultaneously, the user rotates the damping sleeve 32, moving the support plate 34 and sponge pad 35 on the bracket 33 to the front of the seat cushion 13. The user then kneels on the support plate 34 and sponge pad 35 with their feet together, ensuring their legs are firmly restrained. As the user leans further towards the backrest 15, the user's lumbar region receives better stretching, further enhancing the fatigue relief effect.
