Description

Technical Field

[0001] This utility model relates to the field of seating technology, and in particular to a seat with an electrically adjustable lumbar support. Background Technology

[0002] As an essential piece of equipment in daily life and office settings, the comfort and health support performance of chairs directly affect the user's physical condition. With the increasing number of people sitting for long periods, lumbar health problems are becoming increasingly prominent. As a key component for maintaining the natural physiological curvature of the spine and reducing lumbar pressure, the rationality of the chair's lumbar support design is receiving more and more attention. However, the mainstream chairs on the market still have many technical deficiencies in lumbar support that urgently need to be addressed.

[0003] Currently, the seat depth design of most chairs is generally unreasonable, resulting in prominent problems of lumbar unsupported movement. In pursuit of appearance or versatility, most chairs have a seat depth of more than 50 centimeters. This excessively deep seat depth design creates a significant gap between the user's lower back and the chair back (i.e., the "empty back" phenomenon), forcing the spine to bend into a C-shape, which increases the pressure on the lumbar intervertebral discs by 300-400 Pascals. Long-term use can easily lead to diseases such as lumbar muscle strain and lumbar disc herniation.

[0004] To fill the gap in the lumbar region, existing technologies use a fixed support at the front of the chair back to support the user's lumbar region. However, since different users have different body sizes, the fixed support cannot be adjusted to tilt forward to support the user's lumbar region, making it impossible to fully and comfortably match the lumbar region of different users. Therefore, it has the disadvantage of being inconvenient to use. Utility Model Content

[0005] The present invention aims to provide a seat with an electrically adjustable lumbar support to solve the problem mentioned in the background art. In the prior art, a fixed support is designed at the front of the backrest to support the user's waist. However, since different users have different body sizes, the fixed support cannot be adjusted to tilt forward to support the user's waist, which makes it impossible to fully and comfortably match the waist of different users, thus causing inconvenience in use.

[0006] The technical solution adopted by this utility model to solve the technical problem is as follows: A seat with an electrically adjustable lumbar pillow includes a chair leg, a seat, a backrest, a lumbar pillow, and a headrest; the seat is fixedly disposed on the top of the chair leg, the backrest is fixedly disposed on the top rear part of the seat, the top of the lumbar pillow is rotatably connected to the front part of the backrest, the headrest is fixedly disposed on the front part of the backrest and is correspondingly located above the lumbar pillow, and an electrically adjustable push rod is provided inside the backrest, the electrically adjustable push rod is connected to the rear part of the lumbar pillow, and the electrically adjustable push rod is used to push the lumbar pillow forward.

[0007] In some embodiments, the backrest has a back frame inside, the bottom of the electric push rod is hinged to the back frame, the lumbar pillow has a pillow frame inside, the top of the pillow frame is hinged to the front of the back frame, the top of the electric push rod has an output shaft, and the output shaft at the top of the electric push rod is hinged to the rear of the pillow frame.

[0008] In some embodiments, armrests are provided on both sides of the seat, and the height of the armrests is greater than the height of the seat.

[0009] In some embodiments, the top of the armrest is provided with a sponge support.

[0010] In some embodiments, the bottom of the chair legs is provided with a plurality of casters.

[0011] In some embodiments, the back frame is made of aluminum alloy, iron, or stainless steel.

[0012] In some embodiments, the pillow frame is made of aluminum alloy, iron, or stainless steel.

[0013] Compared with the prior art, the beneficial effects of this utility model are: In this invention, a user can sit on a seat supported by chair legs, with their back resting against the backrest at the top rear of the seat, their lower back against a lumbar support at the front of the backrest, and their head against a headrest at the front of the backrest. Because different users have different body shapes, different users require different lumbar support angles for a more comfortable fit. When adjusting the lumbar support angle, an electric actuator pushes the lumbar support forward. Since the top of the lumbar support is rotatably connected to the front of the backrest, when the lumbar support is pushed forward by the electric actuator, the lower part of the lumbar support tilts forward to support the user's lower back. Thus, the user can control and adjust the lumbar support angle via the electric actuator for a more comfortable fit, improving the user's comfort when using this chair. It has the advantages of being practical and convenient. Attached Figure Description

[0019] This utility model provides the following technical solution: a seat 100 with an electrically adjustable lumbar pillow, including a chair leg 10, a seat 20, a backrest 30, a lumbar pillow 40, and a headrest 50; the seat 20 is fixedly disposed on the top of the chair leg 10, the backrest 30 is fixedly disposed on the top rear part of the seat 20, the top of the lumbar pillow 40 is rotatably connected to the front part of the backrest 30, and the headrest 50 is fixedly disposed on the front part of the backrest 30 and is correspondingly located above the lumbar pillow 40; an electrically adjustable push rod 60 is provided inside the backrest 30, and the electrically adjustable push rod 60 is connected to the rear part of the lumbar pillow 40 for transmission, and the electrically adjustable push rod 60 is used to push the lumbar pillow 40 to tilt forward.

[0020] In the seat 100 with an electrically adjustable lumbar support provided in this embodiment, a user can sit on a seat 20 supported by chair legs 10. The user's back can lean against the backrest 30 at the top rear of the seat 20, the user's lower back can rest against the lumbar support 40 at the front of the backrest 30, and the user's head can rest against the headrest 50 at the front of the backrest 30. Since different users have different body shapes, different users require different forward tilt angles of the lumbar support 40 for a more comfortable fit. When the forward tilt angle of the lumbar support 40 needs to be adjusted, the electrically adjustable rod 60 moves to push the lumbar support 40 forward. Since the top of the lumbar support 40 is rotatably connected to the front of the backrest 30, when the lumbar support 40 is pushed forward by the electrically adjustable rod 60, the lower part of the lumbar support 40 tilts forward to rest against the user's lower back. Thus, the user can control and adjust the forward tilt angle of the lumbar support 40 through the electrically adjustable rod 60 to more comfortably fit their lower back, thereby improving the user's comfort when using this seat. It has the advantages of being practical and convenient.

[0021] In some embodiments, the backrest 30 has a backrest frame 301 inside, the bottom of the electric push rod 60 is hinged to the backrest frame 301, the lumbar pillow 40 has a pillow frame 401 inside, the top of the pillow frame 401 is hinged to the front of the backrest frame 301, the top of the electric push rod 60 has an output shaft 601, and the output shaft 601 at the top of the electric push rod 60 is hinged to the rear of the pillow frame 401.

[0022] In specific implementation: When adjusting the forward tilt of the lumbar pillow 40 via the operation of the electric push rod 60, the output shaft 601 at the top of the electric push rod 60 extends forward to push the pillow frame 401. The bottom of the electric push rod 60, hinged to the back frame 301, can rotate under force; the output shaft 601 at the top of the electric push rod 60, hinged to the rear of the pillow frame 401, can rotate under force; and the top of the pillow frame 401, hinged to the front of the back frame 301, can rotate under force. Thus, the output shaft 601 at the top of the electric push rod 60 can push the lower part of the pillow frame 401 forward, thereby adjusting the forward tilt angle of the pillow frame 401, and ultimately adjusting the forward tilt angle of the entire lumbar pillow 40 to more comfortably support the user's lower back. Through this configuration, the electric push rod 60 can effectively adjust the forward tilt angle of the lumbar pillow 40 to support the user's lower back.
