Description

Technical Field

[0001] The utility model relates to the technical field of seat supplies, in particular to an adjustable multi-functional air lumbar support. Background Art

[0002] A seat is a seating tool with a backrest and some also have armrests; in order to improve the comfort of users, existing seats usually add a lumbar support to the backrest to meet the usage needs of different users. For existing office seats and vehicle seats, most of the lumbar supports and the backrests of the seats are integrally designed and not easy to adjust. Due to structural limitations, when the existing split-type lumbar support is placed at the backrest position during use, it is mostly constrained by a restraint strap, which easily causes the lumbar support to shake during use and cannot be adjusted for support, making it difficult to synchronously adapt to people of different body types. Therefore, it is relatively lacking in comfort and cannot well meet the usage needs of users. Summary of the Utility Model

[0019] Such as Figure 1As shown in the figure, an embodiment of the present utility model provides an adjustable multi-functional air lumbar support, which includes a lumbar support body 100, and an adjustment structure and a mounting structure are provided on the lumbar support body 100; the adjustment structure is used to adjust the support effect of the lumbar support during use, and the mounting structure is used for installation according to different seats. The mounting structure provided in this embodiment includes an adjustment belt 200 and a fixing belt 300 respectively located at the upper end and the lower end of the lumbar support body 100. Insertion openings are arranged at intervals up and down on the adjustment belt 200, and an upper fixing strip 400 is inserted into the insertion openings. Clasps that can be engaged with each other are provided at both ends of the upper fixing strip 400; a plurality of clamping blocks 500 are arranged at intervals on the lower edge of the fixing belt 300, and an anti-slip surface is provided on the surface of the clamping blocks 500; in this way, the lumbar support body 100 can be installed on different seats through the mounting structure. The adjustment belt 200 of the mounting structure can be installed at the upper end of the seat. The fixing strip is inserted into the insertion opening at the corresponding height to adjust the installation height of the seat. The two ends of the upper fixing strip 400 can be engaged with each other to fix the upper end of the seat. At the same time, each clamping block 500 at the lower end of the fixing belt 300 is inserted into the gap between the seat and the backrest. Since the anti-slip surface is provided on the surface of the clamping block 500, the static friction can be increased, thereby preventing the clamping block 500 from moving, and the reliability is higher. The entire lumbar support body 100 is fixed by using the upper and lower mounting structures, and the installation height is adjusted according to different seat types to achieve the purpose of expanding the scope of application.

[0020] As Figure 1 shown in the figure, the adjustment structure provided in this embodiment includes a support airbag 600 provided inside the lumbar support body 100. The support airbag 600 is connected to a suction pump module 700 for adjusting the inflation volume of the support airbag 600. The suction pump module 700 is connected to a control panel 800 through a control circuit. Through the above settings, the adjustment structure is installed inside the lumbar support body 100 by using the support airbag 600 structure. Different users control the suction pump module 700 through the control panel 800 during use, so as to adjust the inflation volume inside the support airbag 600; thus, corresponding support points can be provided according to the needs of different users; the comfort of supporting the back and waist of different users is improved; in this embodiment, the suction pump module 700 is used to adjust the inflation volume inside the support airbag 600, and an existing air pump structure is adopted. The specific model and specifications are selected according to needs. The air extraction pump module has a built-in power supply for supplying power to the operation of the device. The control panel 800 is mainly used to control operations such as inflation, deflation, and switching on and off. The control panel 800 can be installed on the outside of the lumbar support body 100 for convenient operation of pressing buttons and the like, which will not be elaborated here.

[0021] As described above, in this embodiment, a support airbag 600 is provided inside the lumbar support body 100 to adjust the support height. To provide a more comfortable support effect for the waists and backs of different users, a plurality of airbag chambers 610 that are spaced apart vertically and communicate with each other are provided inside the support airbag 600. The airbag chambers 610 are arranged in a spindle shape, and the sizes of the respective airbag chambers 610 gradually increase from top to bottom. The suction pump module 700 is connected to the airbag chamber 610 at the lowermost end. The airbag chambers 610 are arranged from top to bottom and their sizes gradually increase. When inflating, the suction pump module 700 preferentially inflates the airbag chamber 610 at the lowermost end. When in use, each airbag chamber 610 is inflated in sequence according to the amount of inflated air by the user, thereby adjusting the support height to facilitate the use by different users.

[0022] As Figure 1 shown, in practical applications, the lumbar support body 100 provided in this embodiment includes an elastic lumbar support inner core 110. The support airbag 600 is installed in an installation cavity provided inside the lumbar support inner core 110. A detachable lumbar support outer cover 130 is further provided on the surface of the lumbar support inner core 110. In this way, the lumbar support inner core 110 plays a role in supporting the waist, and the lumbar support outer cover 130 can be detached and cleaned after use. In addition, in this embodiment, a plurality of ventilation holes arranged in an array are provided on the front side of the lumbar support outer cover 130 corresponding to the lumbar support body 100. The ventilation holes can play a role in ventilation and improve the breathability of the lumbar support.

[0023] As Figure 1 shown, in this embodiment, arc-shaped support flanks 120 are provided on both sides of the lumbar support inner core 110. The support flanks 120 can play a role in supporting both sides of the waist, making the wrapping property of the seat stronger. When used for a vehicle seat, the riding comfort can be improved.

[0024] As described above, the support airbag 600 is connected to the air extraction pump module. To ensure the stability of the installation of the suction pump, in this embodiment, an installation port 140 for installing the suction pump module is provided on one side of the lumbar support inner core 110. A protective piece for opening or closing the installation port 140 is provided at the position of the lumbar support outer cover 130 corresponding to the installation port 140. When in use, the suction pump module 700 can be inserted into the installation port 140. The protective piece can be opened during inflation and deflation to promote air flow, and the protective piece is closed after inflation is completed. The protective piece is connected by a zipper structure, which is convenient for the user to operate.

[0025] As Figure 1 shown, in practical applications, to prevent the middle position of the lumbar support body 100 from shaking, in this embodiment, restraint straps 150 are provided on both sides of the lumbar support outer cover 130 corresponding to the lumbar support body 100. Adhesive parts that can be adhered to each other are provided at the ends of the restraint straps 150. The restraint straps 150 can be wound around the seat and adhered to each other through the adhesive parts to further improve the stability of the seat.

[0026] As Figure 1 shown, in this embodiment, a neck support portion 160 arranged in a spindle shape is further provided in the lumbar support inner core 110 corresponding to the human neck, and the neck support portion 160 has resilience. In this way, the neck support portion 160 can support the user's neck position, and the use of a material with resilience provides higher comfort.
