[0026] To make the technical problems solved, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0027] There is a point where the human shoulder separates from the backrest; above this point, there is a gap between the shoulder and the backrest. Therefore, existing vehicle seats are equipped with shoulder airbags. When inflated, these airbags lift the seat back to compensate for this gap, allowing the seat back to support the shoulders. However, the gap between the shoulder and backrest increases with height. Even with the existing shoulder airbags, a gap remains between the lifted seat back and the upper part of the shoulder (neck and shoulder area), preventing a proper fit. This leads to shoulder fatigue during long journeys, reducing the comfort of the vehicle seat.

[0028] To address the aforementioned problems, this utility model provides a vehicle seat.

[0029] like Figures 1 to 4 As shown, an embodiment of the present invention provides a vehicle seat, including a backrest 5 and a shoulder airbag assembly. The backrest 5 includes a backrest frame 51 and a backrest foam 53 installed on the backrest frame 51.

[0030] It's understandable that a cover is installed on the front of the backrest foam 53. When the driver or passenger sits in the vehicle seat, they are in direct contact with the cover. The backrest frame 51 and the backrest foam 53 provide support for the driver or passenger. The backrest 5 has a shoulder area corresponding to the driver's or passenger's shoulders, and this shoulder area should support the driver's or passenger's shoulders. The location range of this shoulder area was obtained by the designers from a large dataset of shoulder height and width of people of different heights, weights, and sitting postures, so that the shoulder area with a certain support height can support the shoulders of most people.

[0031] In one embodiment of this application, a shoulder airbag assembly is provided, including a first airbag 2, a second airbag 3, and a mounting plate 1. The mounting plate 1 is mounted on a backrest frame 51, and the first airbag 2 and the second airbag 3 are mounted on the mounting plate 1. The first airbag 2 and the second airbag 3 are located on the side of the backrest foam 53 facing the back of the seat. The front of the seat is the side that contacts the driver / passenger, and correspondingly, the back of the seat is the side that faces away from the driver / passenger. Figure 3 As shown, the left and right directions refer to the left and right directions of the seat, and the up and down directions refer to the up and down directions of the seat.

[0032] like Figure 6 As shown, the first airbag 2 is inverted U-shaped. The first airbag 2 includes a main body 21 and two branches 22 connected to the main body 21. The two branches 22 are located below the main body 21 and are spaced apart along the left and right directions of the seat. The second airbag 3 is located on the side of the main body 21 facing away from the mounting plate 1. The first airbag 2 and the second airbag 3 can lift the shoulder area of ​​the backrest 5 when inflated.

[0033] Specifically, the driver and passengers can control the air source to inflate the first air bag 2 and the second air bag 3 by pressing a button or using a controller. After the first air bag 2 and the second air bag 3 are inflated, they expand to push up the backrest foam 53 and deform it to support a certain height, so that the backrest 5 fits the shoulders of the human body.

[0034] The first air bag 2, which consists of the main body 21 and two branches 22, is in an inverted U-shape. After the first air bag 2 is inflated, the main body 21 supports the upper part of the human shoulder, and the two branches 22 support the outer side of the scapula of the human shoulder, which is more in line with the shape of the human shoulder and more conducive to fitting the human shoulder with the backrest 5.

[0035] Furthermore, the gap between the human body and the backrest 5 increases with the increase in height. Therefore, a second air bag 3 is provided on one side surface of the upper main body 21 of the first air bag 2, so that the inflation height of the main body 21 and the second air bag 3 together compensate for the larger gap between the upper part of the human shoulder (i.e., the neck and shoulders) and the backrest 5, and the inflation height of the support 22 compensates for the gap between the lower part of the human shoulder and the backrest 5. Thus, the shoulder area of ​​the backrest 5, which is supported by the first air bag 2 and the second air bag 3, can better fit and support the human shoulder.

[0036] In one embodiment, such as Figure 6 As shown, the second air bag 3 is elongated, and the main body 21 is elongated. The second air bag 3 and the main body 21 have the same shape and size. The upper side of the second air bag 3 is aligned with the upper side of the main body 21.

[0037] When the upper side of the second air bag 3 is offset upward from the upper side of the main body 21, there will be an area on the second air bag 3 that cannot support the shoulders of the personnel. However, when the upper side of the second air bag 3 is aligned with the upper side of the main body 21, the second air bag 3 as a whole can share the gap between the backrest 5 and the shoulders of the personnel with the main body 21, thereby improving the utilization rate of the second air bag 3 and reducing its volume.

[0038] In some embodiments, the second airbag 3 preferably achieves substantial surface coverage with the main body 21, meaning the second airbag 3 just covers the surface of the main body 21. In other embodiments, at least the dimension of the second airbag 3 in the vertical direction of the seat is the same as that of the main body 21, or the dimension of the second airbag 3 in the vertical direction of the seat is smaller than that of the main body 21. This allows the two supports 22 to be exposed, fully utilizing the space formed between the two supports 22 and better adapting to human comfort needs.

[0039] In other embodiments, the second air bag 3 and the main body 21 can be other shapes such as circular or elliptical.

[0040] In one embodiment, the support 22 extends along the left and right sides of the vehicle seat in the vertical direction of the backrest 5.

[0041] In one embodiment, such as Figure 6 As shown, the mounting plate 1 is inverted U-shaped. The mounting plate 1 includes a plate body 11 and two support legs 12 connected to the plate body 11. The two support legs 12 are located on the lower side of the plate body 11 and are spaced apart along the left and right directions of the seat.

[0042] The main body 21 is located on the plate body 11, and the two supports 22 are arranged one-to-one with the two support legs 12, so as to reduce the space occupied by the mounting plate 1 while satisfying the support and fixation of the first air bag 2, and free up more installation space for other parts on the vehicle seat.

[0043] In one embodiment, such as Figure 5 and Figure 6 As shown, the mounting plate 1 also includes a connecting part 13, and the mounting plate 1 is mounted to the backrest frame 51 through the connecting part 13.

[0044] In one embodiment, such as Figure 5 and Figure 6 As shown, the connecting part 13 has a first folded edge 14, a second folded edge 15, and a third folded edge 16. The first folded edge 14 and the third folded edge 16 are spaced apart along the thickness direction of the main body 11. The second folded edge 15 connects the upper side of the first folded edge 14 and the upper side of the third folded edge 16, and the lower side of the first folded edge 14 is connected to the upper side of the main body 11. Hanging holes are formed between the first folded edge 14, the second folded edge 15, and the third folded edge 16. The connecting part 13 is hung on the backrest frame 51 of the vehicle seat through the hanging holes, so that the mounting plate 1 is suspended on the backrest frame 51. The structure is simple and easy to install.

[0045] In one embodiment, such as Figure 5 and Figure 6 As shown, the first folded edge 14 is provided with a first threaded hole extending along its thickness direction, and the third folded edge 16 is provided with a second threaded hole corresponding to and communicating with the first threaded hole. The first folded edge 14 and the third folded edge 16 are connected by screws 4. The screws 4 are threadedly engaged with the first threaded hole and the second threaded hole to prevent the hanging hole of the mounting plate 1 from detaching from the seat frame.

[0046] Of course, to further improve the stability of the mounting plate 1 fixed to the seat frame, the mounting plate 1 can be tied to the backrest frame 51 with cable ties.

[0047] In one embodiment, the first air bag 2 and the second air bag 3 are independently connected to the mounting plate 1 by snap fasteners. The snap fasteners have a simple structure and are easy to assemble and disassemble. In other embodiments, the first air bag 2 can be connected to the mounting plate 1 by snap fasteners, and the second air bag 3 can be attached to the first air bag 2.

[0048] In one embodiment, such as Figure 2 , Figure 3and Figure 4 As shown, the backrest frame 51 includes a spring frame 52 and a frame body. The upper ends of the spring frame 52 are hung on the frame body via hooks on both sides. The spring frame 52 includes multiple horizontal bars and two vertical bars. The two vertical bars are respectively connected to both sides of the multiple horizontal bars. The connecting part 13 is hung on the horizontal bar at the top of the spring frame 52 through the hanging hole.

[0049] Specifically, the first air bag 2 is provided with a first connecting ear, and the second air bag 3 is provided with a second connecting ear. The "first connecting ear" and "second connecting ear" refer to the first connecting ear being integrally formed on the first air bag 2 and not having an inflation function, and the second connecting ear being integrally formed on the second air bag 3 and not having an inflation function. Both the first connecting ear and the second connecting ear are provided with a female buckle for connecting, and the mounting plate 1 is provided with a male buckle for connecting. The female buckle engages with the corresponding male buckle to fix the first air bag 2 and the second air bag 3 on the mounting plate 1.

[0050] In one embodiment, the system further includes an air source, a controller, a first air pipe, and a second air pipe. The air source is connected to the controller, and both the first and second air pipes are connected to the controller. The first air pipe is connected to the first air bag 2, and the second air pipe is connected to the second air bag 3. The controller can control the air source to independently inflate the first air bag 2 and the second air bag 3, allowing the driver and passengers to adjust the inflation height of the first air bag 2 and the second air bag 3 as needed. This adjusts the support height of the air bags for the upper and lower parts of the shoulders, better meeting the support needs of different shoulder positions for the backrest 5.

[0051] Furthermore, the seat backrest 5 typically has a sitting position and a reclining position. When driving, the driver and passengers adjust the seat backrest 5 to the sitting position, and when resting, they adjust the seat backrest 5 to the reclining position, where the seat backrest 5 tilts backward and the driver and passengers lie down on the seat. The distance between the seat backrest 5 and the passenger's shoulders in the sitting position is different from the distance between the seat backrest 5 and the passenger's shoulders in the reclining position. Therefore, the first airbag 2 and the second airbag 3 are designed to inflate independently, allowing the passenger to adjust the inflation height of the first airbag 2 and the second airbag 3 according to the distance between the passenger and the seat backrest 5 in different positions.

[0052] In one embodiment, the control box is provided with two first valve bodies and a second valve body. The first valve body is connected to the first air bag 2, and the second valve body is connected to the second air bag 3. The first and second valve bodies can be opened or closed. The first and second valve bodies have the same structure. Taking the first valve body as an example, when the first valve body is open, the gas from the gas source can flow to the first air bag 2 through the first valve body. When the first valve body is closed, the gas source stops inflating the first air bag 2.

[0053] Understandably, the first air bag 2 can vent through the first valve body, and the second air bag 3 can vent through the second valve body, thus reducing the corresponding inflation height. Alternatively, vents can be provided on the first air bag 2 and the second air bag 3, allowing them to vent through their respective vents and reducing the corresponding inflation height.

[0054] In one embodiment, the air source is an air pump.

[0055] In addition, one embodiment of this utility model provides a shoulder airbag assembly, the structure of which is the same as that of the shoulder airbag assembly in any of the above embodiments, and will not be described again here.

[0056] In addition, one embodiment of the present invention provides a vehicle including the vehicle seat of any of the above embodiments.

[0057] The above-described embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model, and should all be included within the protection scope of this utility model.
