[0028] The embodiments of the present invention are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present invention are described in detail below.

[0029] The following is for reference. Figures 1-5 Describes a seat backrest 1 according to an embodiment of the present utility model.

[0030] like Figures 1-3 As shown, the seat back 1 according to an embodiment of the present invention includes: a back panel assembly 10, foam 20, and a support assembly 30. The back panel assembly 10 is the basic structure of the seat back 1, which can be used to support the entire seat back 1 and ensure its stability and safety. The foam 20 mainly provides comfort for the occupant, and the support assembly 30 mainly provides support.

[0031] like Figure 1 and Figure 2 As shown, the foam 20 is fixed to the front end of the back panel assembly 10, and the support assembly 30 is fixed to the back panel assembly 10. The support assembly 30 is located at the rear end of the foam 20. When the foam 20 deforms in the front-back direction, the support assembly 30 is used to support the foam 20.

[0032] The foam 20 is fixedly mounted at the front of the backrest assembly 10, and the support assembly 30 is fixed to the backrest assembly 10, with the support assembly 30 located at the rear end of the foam 20. The support assembly 30 is installed on the backrest assembly 10, positioned at the rear end of the foam 20, meaning it is positioned between the backrest assembly 10 and the foam 20. When the foam 20 deforms in the front-to-back direction, the support assembly 30 supports it. This ensures that the foam 20 will not shift or collapse due to mutual compression during seat backrest adjustment. It should be noted that the support assembly 30 can be positioned at the upper left and upper right corners of the foam 20 to prevent the corners from lacking internal support and collapsing under pressure.

[0033] Thus, the support component 30 is fixed to the back panel component 10, and the support component 10 is located at the rear end of the foam 20. When the foam 20 deforms in the front-back direction, the support component 10 can support the foam 20. This ensures that the foam 20 will not be misaligned or collapse due to mutual compression during the adjustment of the seat back 1.

[0034] Specifically, such as Figure 5 As shown, the support assembly 30 includes a connector 300 and a support member 301. The connector 300 is fixed to the back panel assembly 10, and the support member 301 is fixed to the connector 300. The connector 300 and the support member 301 are components of the support assembly 30. The connector 300 mainly serves a connecting function, while the support member 301 serves a supporting function. The connector 300 is fixed to the back panel assembly 10, thus enabling the support assembly 30 to be fixed to the back panel assembly 10, and the support member 301 to be fixed to the connector 300. At this time, the support member 301 and the connector 300 form a whole, facilitating the installation and setting of the support assembly 30.

[0035] Among them, such as Figure 5 As shown, the support member 301 includes: a fixing part 302, a first connecting part 303, a second connecting part 304, and a support part 305. The fixing part 302 is fixed to the connector 300. One end of the first connecting part 303 is connected to the fixing part 302. One end of the second connecting part 304 is connected to the other end of the first connecting part 303. The support part 305 is connected between the other end of the second connecting part 304. The other end of the first connecting part 303 extends forward and is inclined upward. The other end of the second connecting part 304 extends backward and is inclined upward.

[0036] It should be noted that the fixing part 302, the first connecting part 303, the second connecting part 304, and the supporting part 305 are components of the supporting member 301. The fixing part 302 mainly serves a fixing connection function, while the first connecting part 303 and the second connecting part 304 both serve a connecting function. The supporting part 305 mainly serves a supporting function. The fixing part 302 is fixed to the connecting member 300. Since the fixing part 302 is fixedly disposed on the connecting member 300, the supporting member 301 can be fixed to the connecting member 300. One end of the first connecting part 303 is connected to... The first connecting part 303 is connected to the fixing part 302, and one end of the second connecting part 304 is connected to the other end of the first connecting part 303. The support part 305 is connected to the other end of the second connecting part 304. That is, the two ends of the first connecting part 303 are connected to the fixing part 302 and the second connecting part 304 respectively, and the two ends of the second connecting part 304 are connected to the first connecting part 303 and the support part 305 respectively. At this time, the fixing part 302, the first connecting part 303, the second connecting part 304 and the support part 305 are connected to form a whole, which facilitates the installation and setting of the support member 301.

[0037] Furthermore, the other end of the first connecting part 303 extends forward and is inclined upward, while the other end of the second connecting part 304 extends backward and is inclined upward. This facilitates the arrangement of the first connecting part 303 and the second connecting part 304, thereby making the position of the support part 305 more reasonable and better supporting the foam 20 when it deforms. Of course, the bending connection between the first connecting part 303 and the second connecting part 304 can improve the overall structural strength of the support member 301, thereby improving the support strength of the support member 301 to a certain extent.

[0038] In addition, such as Figure 3 and Figure 4 As shown, a clearance space 200 is provided on the side of the foam 20 facing the back panel assembly 10, and the support member 301 is disposed in the clearance space 200. The clearance space 200 mainly serves a clearance function. The clearance space 200 is provided on the side of the foam 20 close to the back panel assembly 10, and the support member 301 can be disposed within the clearance space 200. At this time, the internal space of the backrest seat 1 can be reasonably utilized, reducing space occupation, thereby solving the space arrangement problem of the backrest seat 1.

[0039] Of course, such as 2 and Figure 4 As shown, the foam 20 is provided with a first protective surface 201 and a second protective surface 202. The first protective surface 201 is set perpendicular to the horizontal plane and is located above the back panel assembly 10. The second protective surface 202 is set on the side away from the back panel assembly 10. The distance between the first protective surface 201 and the second protective surface 202 and the support member 301 is 'a'. The value of 'a' is in the range of 'a≥25mm'.

[0040] The first protective surface 201 and the second protective surface 202 are components of the foam 20. The first protective surface 201 is perpendicular to the horizontal plane and is located above the back panel assembly 10. The first protective surface 301 is perpendicular to the horizontal plane and is located at the upper end of the back panel assembly 10. The second protective surface 202 is located on the side away from the back panel assembly 10. The distance 'a' between the first and second protective surfaces 201 and the support member 301 is 'a', and the value of 'a' is ≥ 25mm. It should be noted that the distance 'a' between the first and second protective surfaces 201 and the support member 301 needs to meet a certain range. Specifically, the distance 'a' between the first and second protective surfaces 201 and the support member 301 cannot be too small, that is, less than 25mm. This ensures that the support member 301 can provide support. If the distance 'a' between the first and second protective surfaces 201 and the support 301 is too small, it may affect the comfort of the occupants. In addition, it may cause the first protective surface 201 and the second protective surface 202 to be unevenly distributed around the support 301, resulting in excessive local stress. Over time, this may damage the foam 20 or the support 301. At the same time, the distance 'a' between the first and second protective surfaces 201 and the support 301 cannot be too large. If it is too large, the support 301 will not provide adequate support for the foam 20 when it deforms in the front-to-back direction. Furthermore, insufficient support may cause discomfort to the occupants. If the distance 'a' between the first and second protective surfaces 201 and the support 301 is too large, more foam 20 may be needed to fill the gaps, which not only increases costs but may also affect the shape stability of the seat due to excessive material. Therefore, the specific distance 'a' between the first and second protective surfaces 201 and the support 301 can be arranged according to the actual working conditions.

[0041] Furthermore, the seat back 1 also includes a buffer element, which is located at the contact point between the foam 20 and the support member 301. The buffer element primarily serves a cushioning function; its placement at the contact point between the foam 20 and the support member 301 prevents abnormal noises from the seat back 1 and further enhances the comfort and durability of the seat. The buffer element can be made of a noise-absorbing material such as felt.

[0042] In addition, such as Figure 5As shown, both the connector 300 and the support 301 are constructed as wire mesh structures. Wire mesh structures offer advantages such as high strength and small size. Constructing both the connector 300 and the support 301 as wire mesh structures better suits actual working conditions. The high strength of the wire mesh structures does not affect the seat's strength, ensuring stability and safety under various usage conditions. Furthermore, the small size of the wire mesh structures minimizes their impact on the overall weight of the seat. Constructing both the connector 300 and the support 301 as wire mesh structures ensures sufficient support while minimizing the impact on the seat's weight and strength.

[0043] It should be noted that, as Figure 2 As shown, the backrest assembly 10 includes a backrest 100 and a backrest frame 101. Foam 20 is fixed to the backrest 100, the backrest frame 101 is fixed to the backrest 100, and a connector 300 is fixed to the backrest frame 101. The backrest 100 and the backrest frame 101 are components of the backrest assembly 10. The backrest 100 is the main structure of the backrest assembly 10, providing overall rigidity and stability. The backrest frame 101 is a reinforcing structure of the backrest 100, providing additional support and stability to ensure the reliability of the seat under various usage conditions. The foam 20 is fixed to the backrest 100, thus allowing the foam 20 to be fixed to the front end of the backrest assembly 10. The backrest frame 101 is fixed to the backrest 100, and the connector 300 is fixed to the backrest frame 101. This makes the overall setup of the support assembly 30 more robust, stable, and reliable, thereby ensuring the rigidity and stability of the seat. It should be noted that the connector 300 is fixed to the backrest frame 101 by welding. The connector 300 and the backrest frame 101 can be welded together using a special welding machine. This ensures that the weld is smooth, the dimensions are accurate, the structure is simple and elegant, and the connection between the support component 30 and the back panel component 10 is firm and reliable, thereby ensuring the rigidity and stability of the seat.
