DETAILED DESCRIPTION

[0090] 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 inflatable lumbar support on the existing car seat has a consistent bulging height after inflation, a consistent support surface for the waist and back of the human body, a poor match with the physiological curvature of the waist and back of the human body, and a poor supporting effect. Moreover, the existing lumbar support does not provide sufficient lateral support for the human body.

[0091] In response to the above technical problems, an embodiment of the present application provides a seat support assembly, which inflates the lumbar support airbag on the base plate through an air pump device, thereby providing stable support for the human body's waist and back, and uses a fixed base plate fixed to the seat frame to support the side wing airbags. After the side wing airbags are inflated by the air pump device, they can provide lateral support to the occupants. At the same time, a support plate is arranged between the side wing airbags and the foam of the car seat, which can elastically deform after the side wing airbags are inflated and come into contact with the support plate, so that the surface of the side wing airbag facing the human body changes from a curved surface to a flat surface, thereby increasing the lateral contact area of ​​the supporting side wing with the occupant and improving the support stability. In this way, comfortable wrapping of the occupant in the seat is achieved over a wide range at multiple angles.

[0092] 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.

[0093] refer to Figures 1 to 6The seat support assembly provided in the embodiment of the present application includes a lumbar support 100, including a base plate 110 and at least one lumbar support air bag 120, the base plate 110 is installed on the seat back, and the lumbar support air bag 120 is arranged on the base plate 110; a support side wing 200, including a fixed base plate 210, a side wing air bag 220 and a support plate 230, the fixed base plate 210 is fixedly connected to the seat frame and relatively fixed to the base plate 110, the side wing air bag 220 is connected to the fixed base plate 210 and is located between the fixed base plate 210 and the support plate 230, and the support plate 230 is used to abut against the seat foam; an air pump device 300 is connected to the lumbar support air bag 120 and the side wing air bag 220 to inflate the lumbar support air bag 120 and the side wing air bag 220.

[0094] In this way, the lumbar support airbag 120 on the base plate 110 is inflated by the air pump device 300, so as to provide stable support for the waist and back of the human body, and the side wing 200 airbag is supported by the fixed bottom plate 210 fixed to the seat frame. After the side wing airbag 220 is inflated by the air pump device 300, it can provide lateral support to the occupant. At the same time, a support plate 230 is arranged between the side wing airbag 220 and the foam of the car seat, which can elastically deform after the side wing airbag 220 is inflated and contacts with the support plate 230, so that the surface of the side wing airbag 220 facing the human body changes from a curved surface to a flat surface, thereby increasing the lateral contact area of ​​the supporting side wing 200 to the occupant and improving the support stability.

[0095] It is understandable that the waist support airbag 120 and the side wing airbag 220 are both made of flexible materials.

[0096] Exemplarily, the support plate 230 is made of plastic.

[0097] In more examples, there are two supporting wings 200, which are respectively located on both sides of the base plate 110 along the width direction of the base plate 110, and the supporting wings 200 are arranged in front of the lumbar support 100, so that after the occupant sits down and leans on the lumbar support 100, the supporting wings 200 on both sides can realize two-way lateral support for the occupant.

[0098] Furthermore, a first connecting member 130 is provided on the base plate 110. For example, the first connecting member is a tree-shaped rivet, and the base plate 110 is fixedly connected to the seat frame through the tree-shaped rivet.

[0099] In some embodiments, the support plate 230 is provided with a hanging groove 231, the groove wall of the hanging groove 231 has a protrusion 232, the protrusion 232 extends toward the middle side of the hanging groove 231, and the protrusion 232 is configured to be hung with a preset connector on the seat foam.

[0100] In some embodiments, a first hanging component is provided on the side wing airbag 220, and the first hanging component is hung with the protrusion 232. Exemplarily, the first hanging component is a perforated protrusion, which is fixedly connected to the side wing airbag 220, and the perforated protrusion is hung on the protrusion 232 of the hanging groove 231 of the support plate 230 through its own opening.

[0101] In more examples, the first hanging member is a hanging belt, which is connected to the surface of the side wing airbag 220 facing the support plate 230 , and is used to hang with the protrusion 232 of the hanging groove 231 .

[0102] In some embodiments, the side wing airbag 220 has a clamping portion 221 , the fixed base plate 210 is provided with a clamping hole 211 , and the clamping portion 221 is clamped to the clamping hole 211 .

[0103] On the basis of the above embodiment, it can be improved that the clamping portion 221 of the side wing airbag 220 includes a first clamping section, a second clamping section and a third clamping section which are connected in sequence, the first clamping section passes through the clamping port 211, the second clamping section is located on the side of the fixed base plate 210 away from the side wing airbag 220, the third clamping section is provided with a clamping groove, the fixed base plate 210 has a clamping protrusion, the clamping protrusion is located at the edge of the fixed base plate 210 and is arranged close to the clamping port 211, the clamping protrusion of the fixed base plate 210 is clamped in the clamping groove of the third clamping section, thereby further enhancing the connection stability between the side wing airbag 220 and the fixed base plate 210.

[0104] In more examples, the snap-fitting protrusion has an extension portion, which is parallel to the slot of the snap-fitting slot to prevent the snap-fitting protrusion from being separated from the snap-fitting slot. Furthermore, the snap-fitting protrusion has extension portions on opposite sides to further improve the snap-fitting stability between the snap-fitting protrusion and the snap-fitting slot.

[0105] In some other examples, an elastic band 240 is provided around the outer periphery of the supporting side wing 200. Specifically, the elastic band 240 is provided around the outer periphery of the fixed base plate 210, the side wing airbag 220 and the supporting plate 230 to fix the three along the circumferential direction. This can improve the fitting stability among the fixed base plate 210, the side wing airbag 220 and the supporting plate 230 before the supporting side wing 200 is assembled with the seat frame or after the supporting side wing 200 is removed from the seat frame.

[0106] In a possible embodiment, the seat support assembly also includes a controller, which is fixed to the back of the base plate 110. The controller has an air inlet port and multiple air outlet ports. The air pump device 300 includes an air pump 310, and the air pump 310 is connected to the air inlet port through an air pump air pipe 360. The multiple air outlet ports include side wing air outlet ports, and the side wing air outlet ports are connected to the side wing air bags 220 through side wing air pipes 260. Further, side wing air pipes 260 are provided with side wing springs 270. In this way, the deformation ability of the side wing air pipes 260 can be enhanced, and support can be provided for the side wing air pipes 260 to prevent the air pipes from folding or being blocked when bent or subjected to external forces, thereby ensuring smooth airflow. Further, air pump springs 340 can also be provided in the air pump air pipes 360.

[0107] Furthermore, the fixed bottom plate 210 is provided with two limiting holes at intervals, and the wing air pipe 260 is radially positioned on the side wall of the fixed bottom plate 210 through the wing fixing straps 250 passing through the limiting holes.

[0108] In some embodiments, the waist support airbag 120 includes a first airbag 121 connected to the base plate 110 , having a first curved edge 1211 , having a first arc segment 1211 a , and the first arc segment 1211 a is concave toward one side of the middle of the first airbag 121 .

[0109] By providing the first air bag 121 with a first curved edge 1211, and the first curved edge 1211 with a first arc segment 1211a, the first arc segment 1211a is concave toward one side of the middle of the first air bag 121, so that after the first air bag 121 is inflated by the pumping device 300, the thickness of the middle part itself is smaller than the thickness of the two side parts. In this way, the middle area of ​​the first air bag 121 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.

[0110] In some embodiments, the first air bag 121 further has a first straight side 1212 , and the first straight side 1212 is opposite to the first curved side 1211 .

[0111] In this way, along the width direction of the first airbag 121, after the first airbag 121 is inflated, the thickness of the upper part of the first airbag 121 is greater than that of the lower part, which can further serve as a lumbar curve 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.

[0112] In some embodiments, the lumbar support airbag 120 further includes a second airbag 122, which is connected to the substrate 110 and covers at least a portion of the first airbag 121. The second airbag 122 has a second curved edge 1221, and the second curved edge 1221 has a second arc segment 1221a, and the second arc segment 1221a is concave toward one side of the first airbag 121.

[0113] Through the above design, the second air bag 122 is added to the base plate 110 to further provide support for the upper back of the human body and expand the support area of ​​the lumbar support 100. Moreover, after being inflated, the second air bag 122 with the second arc segment 1221a also cooperates with the first air bag 121 to form a structural form with a thinner middle portion and thicker sides along its length direction, thereby strengthening the lateral support for the human body.

[0114] In some embodiments, the second air bag 122 further has a third curved edge 1222 , the third curved edge 1222 is opposite to the second curved edge 1221 , the third curved edge 1222 has a third arc segment 1222 a , and the third arc segment 1222 a is concave toward one side of the second arc segment 1221 a .

[0115] In this way, the two relatively arranged arc segments not only make the second air bag 122 form a symmetrical structure along its own width direction, and enhance the structural strength both when not inflated and after inflating, but also can further expand the thickness difference between the middle and both sides of the second air bag 122 after inflation, thereby strengthening the supporting performance of the second air bag 122 on both sides along its own length direction for the muscles on both sides of the human spine.

[0116] In some embodiments, the lumbar support airbag 120 also includes a third airbag 123, which is connected to the substrate 110 and covers at least a portion of the second airbag 122. The third airbag 123 has a fourth curved edge 1231, and the fourth curved edge 1231 has a fourth arc segment 1231a. The fourth arc segment 1231a is concave toward the side of the second airbag 122, thereby further improving the support performance for the occupant's waist and back.

[0117] In some embodiments, the third air bag 123 further has a fifth curved edge 1232 , the fifth curved edge 1232 is opposite to the fourth curved edge 1231 , the fifth curved edge 1232 has a fifth arc segment 1232 a , and the fifth arc segment 1232 a is concave toward one side of the fourth arc segment 1231 a .

[0118] Exemplarily, the substrate 110 is a felt board, and the first air bag 121, the second air bag 122 and the third air bag 123 are all fixed to the substrate 110 by the second connecting member 140. For example, the second connecting member 140 is a lock, and the substrate 110 is provided with a plurality of lock openings at intervals. The first air bag 121, the second air bag 122 and the third air bag 123 are all fixed to the substrate 110 by the cooperation of the lock and the lock opening, and the connection is stable and the disassembly is convenient.

[0119] In some embodiments, the air pumping device 300 includes an air pump 310, an air pump protection bag 320 and an air pump fixing tie 330. The air pump protection bag 320 is sleeved on the outer periphery of the air pump 310, the air pump fixing tie 330 is tied to the outer periphery of the air pump protection bag 320, and the air pump protection bag 320 is fixedly connected to the substrate 110 through the air pump assembly tie 350.

[0120] On the basis of the above embodiment, it can be improved that the air outlet port of the controller 500 also includes a first air outlet, a second air outlet and a third air outlet, and the first air bag 121, the second air bag 122 and the third air bag 123 are connected to the first air outlet, the second air outlet and the third air outlet through the first air pipe 124, the second air pipe 125 and the third air pipe 126 respectively, and the first air bag spring 127, the second air bag spring 128 and the third air bag spring 129 are respectively provided in the first air pipe 124, the second air pipe 125 and the third air pipe 126.

[0121] In some embodiments, a seat cushion 400 is also included, and the seat cushion 400 includes a seat plate 410 and a seat cushion air bag 420. The seat cushion air bag 420 is fixedly connected to the seat plate 410, and the seat cushion air bag 420 is connected to the air pump device 300. Exemplarily, the seat cushion air bag 420 is fixedly connected to the seat plate 410 via a third connecting member 450. For example, the third connecting member 450 is a tree-shaped rivet.

[0122] Furthermore, the seat cushion airbag 420 includes a first seat cushion airbag 421 and a second seat cushion airbag 422, and the first seat cushion airbag 421 and the second seat cushion airbag 422 are spaced apart from each other on the seat plate 410, and the air outlet port of the controller 500 also includes a first seat cushion air outlet and a second seat cushion air outlet, and the first seat cushion airbag 421 and the second seat cushion airbag 422 are respectively connected to the first seat cushion air outlet and the second seat cushion air outlet through a first seat cushion connecting air pipe 4211 and a second seat cushion connecting air pipe 4221 to receive the gas from the air pump device 300 distributed and transmitted by the controller 500.

[0123] Furthermore, the first seat cushion connecting air pipe 4211 and the first seat cushion air bag 421, as well as the second seat cushion connecting air pipe 4221 and the second seat cushion air bag 422 are connected via a first joint 440. For example, the first joint 440 is a right-angle joint. Furthermore, a plurality of limit grooves are spaced apart on the seat plate 410. The limit grooves have arc-shaped groove walls that protrude toward the side away from the seat plate 410 to form limit groove openings with the seat plate 410. The first seat cushion connecting air pipe 4211 and the second seat cushion connecting air pipe 4221 are penetrated by limit grooves, which have greater stability.

[0124] In other examples, the controller 500 is an ECU controller (Electronic Control Unit), and the first seat cushion connecting air pipe 4211 and the second seat cushion connecting air pipe 4221 are connected to the air circuit controller through the first ECU connecting air pipe 470 and the second ECU connecting air pipe 480, respectively, wherein the first seat cushion connecting air pipe 4211 and the first ECU connecting air pipe 470 are connected through the first quick-plug connector 4211b, the second seat cushion connecting air pipe 4221 and the second ECU connecting air pipe 480 are connected through the second quick-plug connector 4221b, the first seat cushion connecting air pipe 4211 and the second seat cushion connecting air pipe 4221 are radially limited by the limiting buckle 460, and further, the first ECU connecting air pipe 470 and the second ECU connecting air pipe 480 are respectively provided with a first ECU air pipe spring 471 and a second ECU air pipe spring 481.

[0125] In this embodiment, the ECU is an electronic device responsible for controlling and managing the seat cushion, which can adjust the inflation and deflation states of the seat cushion according to its internal sensor data and user input to provide better comfort and support.

[0126] Furthermore, a first air tube spring 4211 a and a second air tube spring 4221 a are respectively disposed inside the first seat cushion connecting air tube 4211 and the second seat cushion connecting air tube 4221 .
