Description

Technical Field

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

[0002] For most people working today, prolonged sitting at a desk has become the norm. When poor posture occurs, the lumbar spine becomes kyphotic, increasing the posterior intervertebral space. The nucleus pulposus in the intervertebral disc can protrude posteriorly and compress the spinal nerves. Over time, this sitting posture can lead to lumbar spine diseases. Lumbar supports, as a commonly used conservative treatment, are widely applied. They are mainly suitable for those with mild symptoms or those with obvious symptoms that can be relieved by rest. Choosing a suitable lumbar support can help patients recover and consolidate the therapeutic effect.

[0003] In existing technologies, lumbar supports are typically made of flexible or elastic materials and secured to the seat back with straps. While this provides some support for the lower back, the size and effectiveness of the lumbar support are not adjustable. However, after prolonged sitting, a person's lower back requires different levels of support, which a fixed-size lumbar support cannot meet. To address this problem, inflatable lumbar supports have emerged in the prior art, allowing the size of the lumbar support to be adjusted by changing the amount of air inflated.

[0004] However, existing inflatable lumbar supports consist of only a single air bladder. This causes significant changes in the shape of the support after inflation, often resulting in a shape that is wider in the middle and narrower at both ends. This makes it inconsistent with the shape of the human waist and thus fails to provide effective lumbar support. Furthermore, existing inflatable lumbar supports use plugs to control the venting, but this method is difficult to control, easily leading to over-deflation or under-deflation, making it difficult to accurately control the size of the lumbar support. Utility Model Content

[0005] In view of the problems of existing lumbar supports being unsuitable in shape after inflation and inconvenient to control venting, the purpose of this utility model is to provide an inflatable lumbar support for seats, so as to at least partially solve the above problems.

[0006] To achieve the above objectives, the technical solution of this utility model is as follows:

[0007] An inflatable lumbar support for a seat includes a lumbar support body and a strap connected to one side of the back of the lumbar support body. The lumbar support body includes a skin and an inflatable airbag disposed within the skin. The interior of the skin also has two protective wings made of flexible material and adapted to the side of the waist. The protective wings are arranged symmetrically on the left and right sides of the inflatable airbag. An execution panel is fixedly installed on the left or right surface of the lumbar support body. The execution panel is provided with an air inlet and an exhaust outlet. The air inlet and the exhaust outlet are respectively connected to an inflation pipe and an exhaust pipe. Both the inflation pipe and the exhaust pipe are connected to the inflatable airbag after passing through the protective wings. The inflation pipe and the exhaust pipe are respectively equipped with a one-way valve and a solenoid valve. The execution panel is provided with a power interface for supplying power to the solenoid valve. The execution panel is also equipped with an exhaust switch for controlling the on / off state of the solenoid valve.

[0008] In a preferred embodiment, the skin has a filling port, which is closed by a zipper, and both wings are detachably and fixedly connected to the inflatable airbag.

[0009] In a preferred embodiment, both the one-way valve and the solenoid valve are fixedly installed on one side of the inner wall of the actuator panel.

[0010] In a preferred embodiment, the protective wing is provided with an inflation channel and an exhaust channel respectively adapted to the inflation pipe and the exhaust pipe.

[0011] In a preferred embodiment, the execution panel is fitted into a mounting port on the skin.

[0012] In a preferred embodiment, the skin is made of woven fabric or leather material.

[0013] In a preferred embodiment, the flexible material is a sponge, silicone, or latex.

[0014] In a preferred embodiment, the lumbar support body is dumbbell-shaped.

[0015] In a preferred embodiment, the device further includes an electric air pump, which is fixedly installed on one side of the inner wall of the execution panel. The electric air pump is connected between the one-way valve and the air inlet via a pipeline. The electric air pump is also connected to the power interface via a power supply cable. An inflation switch for controlling the start and stop status of the electric air pump is also installed on the execution panel.

[0016] In a preferred embodiment, a filter screen is provided in the air intake port.

[0017] The beneficial effects of this utility model by adopting the above technical solution are as follows: due to the setting of the protective wings on both sides of the inflatable airbag, the lumbar support body can still be restricted by the protective wings after the inflatable airbag is inflated, so that the lumbar support body can still support the waist from both sides; in addition, due to the setting of the solenoid valve on the exhaust pipe and the exhaust switch on the execution panel, the opening and closing state of the solenoid valve can be flexibly and accurately controlled by the exhaust switch, thereby accurately controlling the exhaust volume, so that the size of the lumbar support body can be accurately controlled, thus meeting the usage requirements.

[0028] Example 1

[0029] like Figure 1-3 As shown, this utility model embodiment provides an inflatable lumbar support for a seat, including a lumbar support body 1 and a strap 2 connected to one side of the back of the lumbar support body 1.

[0030] The lumbar support body 1 consists of a skin 3, an inflatable airbag 4, and protective wings 5. The skin 3 is made of fabric or leather. The inflatable airbag 4 and protective wings 5 ​​are arranged inside the skin 3. A horizontal, elongated filling port is provided on the skin 3. The filling port is closed by a zipper 18. The filling port is also located on one side of the back of the lumbar support body 1 to facilitate maintenance and replacement of the inflatable airbag 4 and protective wings 5.

[0031] The wing 5 is made of a flexible material that fits the side of the waist. This flexible material can be sponge, silicone, or latex. Two wings 5 ​​are provided, symmetrically arranged on the left and right sides of the inflatable airbag 4. The two wings 5 ​​are detachably and securely connected to the left and right sides of the inflatable airbag 4, for example, via buttons. This makes the inflatable airbag 4 and the two wings 5 ​​form a unified whole, facilitating the use of the lumbar support body 1. Simultaneously, the inflatable airbag 4 and / or the wings 5 ​​are detachably and securely connected to the inner side of the skin 1, for example, via buttons, further improving the overall structural effect of the lumbar support body 1. In this embodiment, after the inflatable airbag 4 is fully inflated, the lumbar support body 1 takes on a dumbbell shape. The middle position of the lumbar support body 1 corresponds to the inflatable airbag 4, providing direct support to the waist, while the two sides of the lumbar support body 1 correspond to the wings 5, providing support to the sides of the waist.

[0032] In this embodiment, an execution panel 6 is also fixedly installed on the surface of the lumbar support body 1, and the execution panel 6 is installed on the right side of the lumbar support body 1. Figure 1(on the right side), which is convenient to operate and does not affect the use of the lumbar support body 1. Specifically, an installation port is opened on the skin 1, and then the execution panel 6 is fitted into the installation port, for example, by adhesive or screw fixing.

[0033] The execution panel 6 includes a plate-shaped body made of plastic. This plate-shaped body has an air inlet 7 and an exhaust outlet 8, both extending through the inner and outer sides of the plate-shaped body. On the inner side of the plate-shaped body (i.e., inside the lumbar support body 1), the air inlet 7 and exhaust outlet 8 are respectively connected to an inflation pipe 9 and an exhaust pipe 10. Both the inflation pipe 9 and the exhaust pipe 10 connect to the inflatable airbag 4 after passing through the adjacent protective wing 5 (located on the right side). It is easy to understand that the protective wing 5 on the right side has inflation channels and exhaust channels respectively adapted to the inflation pipe 9 and the exhaust pipe 10, thus allowing the inflation pipe 9 and the exhaust pipe 10 to easily pass through the protective wing 5.

[0034] Meanwhile, the inflation pipe 9 and the exhaust pipe 10 are respectively equipped with a one-way valve 11 and a solenoid valve 12. In this embodiment, both the one-way valve 11 and the solenoid valve 12 are fixedly installed on one side of the inner wall of the plate-shaped body of the execution panel 6. One end of the one-way valve 11 (the air inlet end) is connected to the air inlet port 7 through a hose (or directly fixedly connected to the air inlet port 7 from one side of the inner wall of the plate-shaped body), and the other end is connected to the inflation pipe 9. The solenoid valve 12 is configured as a normally closed solenoid valve, one end of which is connected to the exhaust port 8 through a hose (or directly fixedly connected to the exhaust port 8 from one side of the inner wall of the plate-shaped body), and the other end is connected to the exhaust pipe 10.

[0035] In addition, a power interface 13 for supplying power to the solenoid valve 12 is provided on one side of the outer surface of the plate-shaped body of the actuator panel 6. In use, this power interface 13 is connected to the vehicle's power supply via a cable. Simultaneously, an exhaust switch 14 for controlling the on / off state of the solenoid valve 12 is also installed on one side of the outer surface of the plate-shaped body of the actuator panel 6. That is, the exhaust switch 14 is connected in series between the power interface 13 and the solenoid valve 12, thereby controlling the on / off state of the solenoid valve 12 by operating the exhaust switch 14. The exhaust switch 14 can be a push-button switch or a touch switch.

[0036] In use, connect the air inlet 7 to an external air pump (manual, foot-operated, or electric) via a pipe to inflate the airbag 4, making it expand and thicken. Once the lumbar support body 1 reaches the desired thickness, turn off the air pump to stop inflation. Then, use the straps 2 to secure the lumbar support body 1 to the appropriate position on the seat. During use, the expansion degree of the lumbar support body 1 can be increased by restarting the air pump, and the expansion degree of the lumbar support body 1 can be reduced by releasing air through the exhaust switch 14, thus allowing the lumbar support body 1 to meet the user's needs at different times and for different users.

[0037] Example 2

[0038] Its difference from Embodiment 1 is as follows: Figure 4-5 As shown, this embodiment also includes an electric air pump 15, which is fixedly installed on one side of the inner wall of the plate-shaped body of the execution panel 6. The air inlet of the electric air pump 15 is connected to the air inlet port 7 through a hose, and the air outlet of the electric air pump 15 is connected to the air inlet of the one-way valve 11 through a hose. A filter screen 17 is provided in the air inlet port 7.

[0039] In addition, the electric air pump 15 is connected to the power interface 13 via a power supply cable, and an inflation switch 16 for controlling the start and stop status of the electric air pump 15 is also installed on one side of the outer surface of the execution panel 6.

[0040] With this configuration, by integrating the electric air pump 15 inside the lumbar support body 1, it is possible to use the lumbar support without relying on an external air pump.

[0041] The embodiments of this utility model have been described in detail above with reference to the accompanying drawings, but this utility model is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, and these variations still fall within the protection scope of this utility model.
