Description

Technical Field

[0001] This utility model relates to the field of lumbar support cushion technology, specifically a manual / automatic integrated airbag adjustable lumbar support cushion. Background Technology

[0002] Lumbar support cushions are practical tools for people who sit for long periods (such as office workers and drivers) to relieve lumbar pressure and correct posture. Generally, lumbar support cushions use either a plate-type mechanical adjustment mechanism or a flexible foam pad for support. However, existing lumbar support cushions are bulky and inconvenient to carry, affecting their portability. Furthermore, the mechanical adjustment mechanism results in a fixed support angle, making them difficult to use. Therefore, improvements to the existing technology are needed. Utility Model Content

[0003] The purpose of this invention is to provide a manual / automatic integrated airbag adjustable lumbar support cushion, which solves the problems of the lumbar support cushion's size and angle being inconvenient to carry and its adjustment being limited.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. This utility model adds a support bladder, an air bladder, and a connecting tube to the inflatable plate. When using the lumbar support cushion, the support bladder and the inside of the inflatable plate can be inflated by the air bladder or an air pump. The inflated support bladder can then support the user's waist. When it is necessary to carry it, it can be deflated by the hose, thus making the lumbar support cushion more convenient to carry.

[0013] 2. This utility model, by adding an air bladder, connecting tube and manual inflation mechanism to the one-way tube, can support the waist by inflating the inside of the support bladder manually or electrically. The support force and angle of the support bladder can then be adjusted by the amount of inflation, thereby effectively improving the degree of adjustment. Attached Figure Description

[0021] Please see Figure 1-5 A manual / automatic adjustable lumbar support cushion with an airbag design includes an inflatable plate 1. Two symmetrically distributed support bladders 2 are fixedly connected to the outer side of the inflatable plate 1. A flexible heating element 3 is fixedly installed on the front of the support bladder 2. A hose 6 is fixedly connected to the lower right end of the inflatable plate 1. An externally threaded tube 7 is fixedly connected to the lower end of the hose 6. A one-way tube 8 is threadedly connected to the outer side of the externally threaded tube 7. An inflatable bladder 9 is fixedly installed at the lower end of the one-way tube 8. A connecting tube 10 is fixedly connected to the inner lower end of the inflatable bladder 9. A manual inflation mechanism 11 is provided inside the connecting tube 10. An internally threaded tube 12 is fixedly connected to the inner lower end of the connecting tube 10. Two symmetrically distributed fixing rods 15 are fixedly connected inside the one-way tube 8. A moving strip 16 is slidably connected to the outer side of the fixing rod 15. A sealing plug 17 is fixedly connected to the lower end of the moving strip 16. A spring 18 is provided on the outer side of the fixing rod 15.

[0022] Please see Figure 1-5Two flexible heating elements 3 are fixedly connected by a wire 4. A plug 5 is fixedly installed on the outside of the wire 4, which can supply power to the flexible heating elements 3 through the plug 5 and the wire 4. A sealing ring 13 is fixedly connected to the upper end of the internal threaded tube 12. The sealing ring 13 is fixedly connected to the connecting tube 10. The sealing ring 14 can increase the sealing performance at the connection between the air pump tube and the internal threaded tube 12. A sealing ring 14 is fixedly connected to the upper end of the one-way tube 8. The sealing ring 14 contacts the external threaded tube 7. The sealing ring 14 can improve the sealing performance at the connection between the external threaded tube 7 and the one-way tube 8. One end of the spring 18 is fixedly connected to the one-way tube 8, and the other end of the spring 18 is fixedly connected to the moving strip 16. The sealing plug 17 slides in contact with the one-way tube 8. The spring 18 can support the moving strip 16 through its elasticity.

[0023] Please see Figure 1-5 The manual inflation mechanism 11 includes a fixing strip 111. The fixing strip 111 is fixedly connected to the upper part of the inner wall of the connecting pipe 10. A reset frame 112 is slidably connected inside the fixing strip 111. A cover plate 113 is fixedly connected to the upper end of the reset frame 112. A sealing post 114 is fixedly connected to the lower end of the cover plate 113. A second spring 115 is provided on the outer side of the reset frame 112.

The sealing post 114 is fixedly connected to the reset frame 112. The second spring 115 can automatically reset the reset frame 112 through its elastic force.

[0024] The specific implementation process of this utility model is as follows: When in use, press the airbag 9. After the airbag 9 is squeezed, the internal pressure increases. The force of the pressure acts on the surface of the sealing plug 17. When the pressure is greater than the elastic force of the spring 18, the sealing plug 17 can be pushed away from the one-way tube 8. After it is separated, the airflow can enter the interior of the inflation plate 1 and the support bladder 2 through the one-way tube 8. Then release the airbag 9. The airbag 9 fills the interior of the inflation plate 1 with gas, and the internal pressure decreases. When the atmospheric pressure applied to the outside of the sealing column 114 is greater than the elastic force of the spring 115, the sealing column 114 can be pushed away from the connecting tube 10. Then the external gas can flow into the interior of the airbag 9, so that the airbag 9 is reset. Then, the airbag 9 can be repeatedly squeezed to inflate the interior of the inflation plate 1 and the support bladder 2. When there is an air pump nearby, the connection port of the air pump can be connected to the internal threaded tube 12, and the inflation plate 1 and the support bladder 2 can be inflated by the air pump.

[0025] When the support strength needs to be adjusted, only the inflation volume needs to be controlled. When it needs to be carried, the one-way tube 8 can be removed from the external threaded tube 7, and the gas inside the inflation plate 1 can be released through the hose 6.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
