DETAILED DESCRIPTION

[0052] As described in the background technology, a lumbar support is usually provided on a car seat, which generally includes a manual lumbar support, an electric lumbar support and a pneumatic lumbar support, wherein the pneumatic lumbar support is adjusted by an airbag and an air pump system. Passengers can change the support strength and position of the lumbar support by controlling the inflation and deflation of the airbag. However, the existing pneumatic lumbar support has a poor supporting effect on the occupants. The inventor has found that the main reason for this problem is that the airbag of the pneumatic lumbar support is usually a rectangular airbag composed of multiple straight edges, and the thickness of the airbag is consistent when it is inflated, which is not sufficiently compatible with the physiological curve of the human spine, and the support for the waist and back is not good. When the car is turning, the human body is easy to slide relative to the airbag.

[0053] In response to the above technical problems, an embodiment of the present application provides an air bag lumbar support, which includes a first air bag having a first curved edge, and a first arc segment on the first curved edge, wherein the first arc segment is concave toward one side of the middle of the first air bag, so that after the first air bag is inflated by the action of an air pump device, the thickness of the middle part of the first air bag itself is smaller than the thickness of the two side parts. In this way, the middle area of ​​the first air bag will not produce excessive pressure on the human spine, and the support is more uniform. Moreover, the thicker inflated areas on both sides of the arc segment of the air bag can provide lateral support to the human spine and waist, thereby reducing the shaking of the waist and back during driving.

[0054] In order to make the above-mentioned purposes, features and advantages of the embodiments of the present application more obvious and understandable, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work belong to the scope of protection of this application.

[0055] The air bag lumbar support provided in the embodiment of the present application includes a base plate 100, which is installed on a seat back; a first air bag 200, which is connected to the base plate 100, and the first air bag 200 has a first curved edge 210, and the first curved edge 210 has a first arc segment 211, and the first arc segment 211 is concave toward one side of the middle of the first air bag 200; an air pump device 300, which is connected to the first air bag 200 to inflate the first air bag 200.

[0056] In this way, by having a first air bag 200 with a first curved edge 210, and having a first arc segment 211 on the first curved edge 210, the first arc segment 211 is concave toward the middle side of the first air bag 200, so that after the first air bag 200 is inflated under the action of the pumping device 300, the thickness of the middle part itself is less than the thickness of the two side parts. In this way, the middle area of ​​the first air bag 200 will not produce excessive pressure on the human spine, and the support is more uniform. Moreover, the thicker inflated areas on both sides of the arc segment of the air bag can provide lateral support to the human spine and waist, thereby reducing the shaking of the waist and back during driving.

[0057] Exemplarily, the base plate 100 is a felt board having connection holes on opposite sides along its width direction. The felt board is fixedly connected by rivets penetrating the connection holes and preset mounting holes of the seat. For example, the rivet is a tree-shaped rivet 110, which is easy to install and firmly fixed. The serrated structure of the tree-shaped rivet 110 provides a strong fixing force.

[0058] In some embodiments, the first air bag 200 further has a first straight side 220 , and the first straight side 220 is opposite to the first curved side 210 .

[0059] In this way, along the width direction of the first airbag 200, after the first airbag 200 is inflated, the thickness of the upper part of the first airbag 200 is greater than that of the lower part, which can further serve as a lumbar support part to provide support for the lumbar curve of the human body and avoid the lumbar curve from hanging in the air. It is more ergonomically designed, improves the riding experience of the passengers, and reduces the back fatigue of the passengers during long-term riding.

[0060] In some embodiments, the first air bag 200 is fixedly connected to the base plate 100 via a first locking member 400 .

[0061] In this way, while ensuring the connection stability between the first air bag 200 and the base plate 100, the flexibility of installation and disassembly of the two is high.

[0062] Exemplarily, the base plate 100 is a felt board, the first locking component 400 is a first lock buckle, the first lock buckle includes a first male buckle and a first female buckle, the first air bag 200 is provided with a connecting plate on one edge facing the felt board, the first female buckle is fixed on the connecting plate, the first male buckle is fixed on the felt board, and the first air bag 200 is fixedly connected to the felt board via the first lock buckle.

[0063] In some embodiments, a second air bag 500 is further included. The second air bag 500 is connected to the substrate 100 and covers at least a portion of the first air bag 200 . The second air bag 500 has a second curved edge 510 . The second curved edge 510 has a second arc segment 511 . The second arc segment 511 is concave toward one side of the first air bag 200 .

[0064] Through the above design, a second air bag 500 is added to the base plate 100, which can further provide support for the upper back of the human body and expand the supporting area of ​​the lumbar support. Moreover, after being inflated, the second air bag 500 with the second arc segment 511 also cooperates with the first air bag 200 to form a structural form with a thinner middle thickness and thicker sides along its length direction, thereby strengthening the lateral support for the human body.

[0065] In more examples, the air pump device 300 is an integrated pump and valve, which has a first output end and a second output end, the first air bag 200 has a first air inlet, the second air bag 500 has a second air inlet, and the lumbar support also includes a first connecting air pipe 230 and a second connecting air pipe 530, the first connecting air pipe 230 is connected between the first output end and the first air inlet, and the second connecting air pipe 530 is connected between the second output end and the second air inlet.

[0066] Furthermore, an air pipe fixing tie is provided on the outer periphery of the first connecting air pipe 230 and / or the second connecting air pipe 530, which can firmly fix the air pipe in a specific position to prevent it from moving due to vibration or external force during use, thereby ensuring the stability and safety of the air pipe.

[0067] Optionally, a plurality of air pipe fixing ties are arranged at intervals on the outer circumference of the first connecting air pipe 230 and / or the second connecting air pipe 530 .

[0068] Specifically, the air pipe fixing tie includes a first air pipe fixing tie 231 and a second air pipe fixing tie 531. The first air pipe fixing tie 231 is arranged on the periphery of the first connecting air pipe 230 and is located on the side close to the air inlet of the first air bag 200. The second air pipe fixing tie 531 is wrapped around the periphery of the first connecting air pipe 230 and the second connecting air pipe 530 to improve the air supply stability of the air pump device 300 to the first air bag 200 and the second air bag 500.

[0069] In some embodiments, the second airbag 500 further has a third curved edge 520 , which is opposite to the second curved edge 510 . The third curved edge 520 has a third arc segment 521 , and the third arc segment 521 is concave toward one side of the second arc segment 511 .

[0070] In this way, the two relatively arranged arc segments not only make the second air bag 500 form a symmetrical structure along its own width direction, and the structural strength both when not inflated and after inflating is enhanced, but also can further expand the thickness difference between the middle and both sides of the second air bag 500 after inflation, thereby strengthening the supporting performance of the second air bag 500 on both sides along its own length direction for the muscles on both sides of the human spine.

[0071] In some embodiments, the second air bag 500 is fixedly connected to the base plate 100 via a second locking member 600 .

[0072] Such an arrangement ensures the connection stability between the second air bag 500 and the base plate 100 while providing the two with high installation and disassembly flexibility.

[0073] In some embodiments, a protection component 700 is further included. The protection component 700 includes a protection bag 710 . The protection bag 710 is sleeved on the outer periphery of the air pumping device 300 .

[0074] In this way, the air pumping device 300 can be effectively prevented from being subjected to external physical impact, vibration or other mechanical damage, thereby extending the service life of the air pumping device 300. Moreover, the protective bag 710 can have a certain sound insulation effect, reduce the impact of noise on passengers in the car, and improve riding comfort.

[0075] Exemplarily, the air pumping device 300 is an air pump, which is a pump and valve integrated into one, and the air pump is placed in a protective bag 710 .

[0076] In some embodiments, the protection assembly 700 further includes a binding member 720 , which is bound to the outer periphery of the protection bag 710 .

[0077] In this way, the protective bag 710 can be firmly fixed at a specific position inside the seat through the binding piece 720, further preventing the air pump device 300 from being displaced or loosened during the driving of the vehicle, thereby ensuring its stability and reliability.

[0078] For example, the binding member 720 is a double-ended cable tie, which is relatively simple and convenient for installation and removal. Maintenance personnel or users can easily fix or remove the protective bag 710, which is convenient for maintenance and inspection of the air pumping device 300. Moreover, the double-ended cable tie can adjust the tightness as needed to ensure that the protective bag 710 can tightly wrap the air pumping device 300 to provide better protection. At the same time, the tightness can also be adjusted according to the specific situation to adapt to different installation environments and needs.

[0079] In more examples, the protective assembly 700 also includes a pump body fixing tie 730, which is arranged at intervals with the binding member 720 on the periphery of the protective bag 710 to prevent the air pump from moving due to vibration or external force during operation, thereby ensuring its stability and safety.

[0080] In some embodiments, a silencer tank 800 is further included, and the silencer tank 800 is connected between the air pump device 300 and the first air bag 200 .

[0081] Exemplarily, the pumping device 300 is a pump-valve integrated device, and the silencer tank 800 is connected between the pump-valve integrated device and the first air bag 200. In this way, the noise generated by the pump-valve integrated device during inflation or deflation can be reduced. Specifically, the silencer tank 800 can play a buffering role, making the airflow more stable and avoiding the sudden noise generated when the airflow directly enters the air bag. By reducing the pressure fluctuation between the pump-valve integrated device and the first air bag 200, the silencer tank 800 can reduce the mechanical stress of the system, thereby extending the service life of the air pump and the air bag. The use of the silencer tank 800 can significantly improve the comfort and user experience of the air bag waist support, making it quieter and more comfortable during use.

[0082] Exemplarily, there are two silencer tanks 800, and the air pumping device 300 is an air pump. The two silencer tanks 800 are respectively connected to the air pump and the first air bag 200, and between the air pump and the second air bag 500. Further, the two silencer tanks 800 are respectively connected to the air pumping device 300 through the first pump body connecting pipe 310 and the second pump body connecting pipe 320.

[0083] In more examples, a muffler tank fixing tie 810 is provided on the outer periphery of the muffler tank 800, so that by firmly fixing the muffler tank 800, the vibration and noise generated during operation can be reduced, and the working environment quality of the equipment can be improved. The muffler tank 800 is prevented from causing damage to itself or surrounding equipment due to movement, and the service life of the equipment is extended.

[0084] In some embodiments, the air bag lumbar support also includes a controller, which is arranged on the side of the substrate 100 away from the first air bag 200, the air pumping device 300 is a pump-valve integrated with the controller, which is electrically connected to the pump-valve, and the controller has a first control button, a second control button and a third control button. Pressing the first control button will turn on the air pump and the first air valve to inflate the first air bag 200, and the pressing time determines the filling degree of the first air bag 200.

[0085] Pressing the second control button will turn on the air pump and the second air valve to inflate the second air bag 500 , and the pressing time determines the filling degree of the second air bag 500 .

[0086] Pressing the third control button will turn on the air pump, the first air valve and the second air valve to inflate the first air bag 200 and the second air bag 500. The pressing time determines the filling degree of the first and second air bags 500.

[0087] The controller also has a fourth control button. Pressing the fourth control button will close the air pump, the first and second air valves, and deflate the first and second air bags 500. The pressing time determines the filling degree of the first and second air bags 500.

[0088] In this way, the air bag waist support of the embodiment of the present application can adjust the height of each air bag individually to meet the requirements of different users for improving waist comfort, so that the support air bag can better fit the natural curvature of the spine.

[0089] In a second aspect, an embodiment of the present application further provides a car seat, comprising a seat body and an air bag lumbar support as provided in any embodiment of the first aspect.
