[0045] The present utility model will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0046] Refer to Figure 1 , the present utility model provides an automotive seat, which is used to solve the problem that when the backrest of the existing automotive seat rotates backward for adjustment, the height difference between the lower end of the backrest and the tail end of the seat cushion will cause poor comfort, and the greater the adjustment angle of the backrest, the more obvious the discomfort. The automotive seat of the present utility model is provided with a connecting rod and a lifting frame assembly, so that the lifting frame assembly can be linked with the backrest frame assembly. During the process of the backrest frame assembly rotating backward for adjustment, the rear end of the lifting frame assembly can be driven to lift upward through the connecting rod, compensating for the height difference caused by the rotation of the lower end of the backrest, and achieving the effect of comfortable reclining of the seat. The structure of an automotive seat of the present utility model will be described below in conjunction with the accompanying drawings.

[0047] Refer to Figure 1 , which shows a schematic structural diagram of the frame assembly of the automotive seat of the present utility model. The structure of the automotive seat of the present utility model will be described below in conjunction with Figure 1 .

[0048] As Figure 1As shown in the figure, the vehicle seat of the present utility model includes a seat cushion frame assembly 10 and a backrest frame assembly 20. The backrest frame assembly 20 can rotate relative to the seat cushion frame assembly 10, realizing the rotational adjustment function of the vehicle seat backrest. The seat cushion frame assembly 10 includes seat cushion side plates 11 arranged oppositely and a lifting frame assembly 30. The lifting frame assembly 30 has opposite front end 31 and rear end 32. The front end 31 of the lifting frame assembly 30 is hinged to the seat cushion side plate 11 of the seat cushion frame assembly 10, and the rear end 32 of the lifting frame assembly 30 is drivingly connected to the backrest frame assembly 20 through a connecting rod 40. One end of the connecting rod 40 is hinged to the backrest frame assembly 20, and the other end is slidably connected to the lifting frame assembly 30. The rear end 32 of the lifting frame assembly 30 can be lifted upward or lowered downward through the hinge connection at the front end 31.

[0049] When the backrest frame assembly 20 rotates relative to the seat cushion side plate 11 of the seat cushion frame assembly 10, the backrest frame assembly 20 can drive the rear end of the lifting frame assembly 30 to be lifted or lowered through the connecting rod 40. Specifically, when the backrest frame assembly 20 rotates backward for adjustment, through the transmission of the connecting rod 40, the rear end 32 of the lifting frame assembly 30 is lifted upward relative to the front end 31, compensating for the height difference caused by the rotational adjustment of the backrest and improving the comfort of the vehicle seat. When the backrest frame assembly 20 rotates forward, through the transmission of the connecting rod 40, the rear end 32 of the lifting frame assembly 30 is lowered relative to the front end 31, enabling the lifting frame assembly 30 to return to the state before lifting.

[0050] In a specific embodiment of the present utility model, the backrest frame assembly 20 of the vehicle seat of the present utility model can be rotated and adjusted relative to the seat cushion frame assembly 10 to a flat state. During the rotation and adjustment of the backrest frame assembly 20, the rear end 32 of the lifting frame assembly 30 is lifted upward around the front end 31 through the transmission of the connecting rod 40 until the rear end 32 of the lifting frame assembly 30 is close to the upper surface of the backrest frame assembly 20. The height difference between the rear end 32 of the lifting frame assembly 30 and the upper surface of the backrest frame assembly 20 only needs to meet ergonomics. Preferably, the height difference between the two is zero.

[0051] Combined Figure 10 and Figure 11 As shown in the figure, the backrest 2 of the vehicle seat can rotate backward from the state of the design position to a flat state. At this time, the vehicle seat can also be referred to as the large reclining position. The rear end of the lifting pad 3 formed by the lifting frame assembly 30 is lifted upward, and the upper surface of the lifting pad 3 is close to the upper surface of the backrest 2, which can avoid the discomfort caused to the human waist by the large height difference between the backrest 2 and the seat cushion 1. From Figure 10 and Figure 11From the displayed effect, the rear end of the lifting pad 3 is lifted from a state where it is generally flush with the rear end of the seat cushion 1 to the upper surface above the seat cushion 1 and close to the lower end of the backrest 2.

[0052] Furthermore, as Figure 3 shown, the designed position of the backrest frame assembly 20 of the vehicle seat is such that the backrest frame assembly 20 is generally in an upright state. At this time, the rear end 32 of the lifting frame assembly 30 is placed inside the seat cushion frame assembly 10, and the state is as Figure 10 shown. In this state, the backrest frame assembly 20 can rotate forward by a certain angle, as Figure 4 and Figure 9 shown. As the backrest frame assembly 20 rotates forward, the rear end of the lifting pad 3 is driven by the connecting rod 40 to descend, Figure 9 and in the displayed effect, the rear end of the lifting pad 3 is lower than the rear end of the seat cushion 1.

[0053] In a specific embodiment of the present invention, as Figure 1 shown, the rear end 32 of the lifting frame assembly 30 is arranged close to the lower end 22 of the backrest frame assembly 20.

[0054] When setting the lifting frame assembly 30, the lifting frame assembly 30 can be embedded in the seat cushion frame assembly 20. The front end 31 of the lifting frame assembly 30 is hinged to the corresponding part of the seat cushion frame assembly 20. The rear end 32 of the lifting frame assembly 30 is arranged close to the lower end of the backrest frame assembly 20, and the rear end 32 of the lifting frame assembly 30 can rotate upward around the front end 31 to achieve lifting or rotate downward to achieve lowering.

[0055] In a specific embodiment of the present invention, as Figures 1 to 3 shown, a bracket 51 extending outward is formed at the lower end 22 of the backrest frame assembly 20 close to the rotation connection part with the seat cushion side plate 11 of the seat cushion frame assembly 10, or a bracket 51 is connected; one end of the connecting rod 40 is hinged to the bracket 51.

[0056] The end of the connecting rod 40 is provided with a hinge hole 42, and the bracket 51 is also provided with a through hole. The hinge hole 42 and the through hole are aligned and then the hinge connection is achieved through a bolt bushing or a rivet passed through.

[0057] The bracket 51 can be a separate component and is connected to the lower end 22 of the backrest frame assembly 20 by welding or screws, etc. The bracket 51 can also be a part of the backrest frame assembly 20, that is, integrally formed with the backrest frame assembly 20.

[0058] Preferably, as Figure 1 and Figure 3As shown, the backrest frame assembly 20 includes a pair of backrest side plates 21, a backrest top plate 23 connected to the tops of the pair of backrest side plates 21, an upper connecting plate 24 connected to the upper parts of the pair of backrest side plates 21, and a lower connecting plate 25 connected to the lower parts of the pair of backrest side plates 21. Further, the pair of backrest side plates 21 includes a lower support plate 211 and an upper support plate connected to the lower support plate 211. In combination with Figure 10 As shown, a backrest foam and a backrest cover are made on the backrest frame assembly 20, thereby forming the backrest 2. The mounting position of the bracket 51 is at the lower end 22 of the lower support plate 211 of the backrest frame assembly 20.

[0059] In a specific embodiment of the present invention, as Figures 1 to 3 As shown, the lifting frame assembly 30 includes oppositely arranged side connecting plates 33. The front ends of the side connecting plates 33 are hinged to the seat side plates 11 of the seat frame assembly 10; there are two connecting rods 40, which are respectively hinged on both sides of the backrest frame assembly 20, and the other ends of the connecting rods 40 are slidably connected to the corresponding side connecting plates 33.

[0060] The side connecting plates 33 of the lifting frame assembly 30 are arranged close to the lower support plates 211 of the corresponding backrest frame assemblies 20. The rear ends of the side connecting plates 33 are slidably connected to the corresponding ends of the connecting rods 40, and the other ends of the connecting rods 40 are hinged to the brackets 51 at the lower ends of the corresponding lower support plates 211. The two arranged connecting rods 40 can synchronously lift or lower the two side connecting plates 33, improving the stability of the lifting and lowering adjustment process of the lifting frame assembly 30.

[0061] Further, sliding grooves 331 are formed in the side connecting plates 33 corresponding to the connecting rods 40; sliding blocks 41 are provided on the connecting rods 40 corresponding to the sliding grooves 331 and are slidably arranged in the sliding grooves 331. During the process of the backrest frame assembly 20 rotating and adjusting relative to the seat side plates 11 of the seat frame assembly 10, the sliding blocks 41 can slide in the sliding grooves 331.

[0062] As Figure 6 and Figure 4 As shown, when the backrest frame assembly 20 rotates forward and adjusts to a certain angle, the sliding blocks 41 slide to the first ends of the sliding grooves 331. The mutual cooperation between the first ends of the sliding grooves 331 and the sliding blocks 41 limits the forward rotation angle of the backrest frame assembly 20. At this time, the backrest frame assembly 20 can only rotate backward and adjust. In the Figure 6 shown state, the perpendicular line of the rotation center of the backrest frame assembly 20 and the center connection line of the rotation center and the hinge point center of the end of the connecting rod 40 are located on the same straight line.

[0063] As Figure 7 and Figure 3As shown, when the backrest frame assembly 20 is in its normal design position, the sliding block 41 slides in the middle of the sliding groove 331. At this time, the backrest frame assembly 20 can be rotated forward or backward for adjustment. Figure 7 In the state shown, the perpendicular line of the rotation center of the backrest frame assembly 20 and the center line connecting the rotation center and the center of the hinge point of the end of the connecting rod 40 form a certain angle A, and this angle A is an acute angle, which is equivalent to the backrest frame assembly 20 Figure 6 in the state shown has rotated backward by an angle A relative to the seat cushion frame assembly 10.

[0064] As Figure 8 and Figure 5 shown, when the backrest frame assembly 20 is in the flattened state, the sliding block 41 slides to the second end of the sliding groove 331. At this time, the backrest frame assembly 20 can only be rotated forward for adjustment. Figure 8 In the state shown, it is equivalent to the backrest frame assembly 20 Figure 6 in the state shown has rotated backward and lain flat relative to the seat cushion frame assembly 10.

[0065] As Figures 6 to 7 shown, when the backrest frame assembly 20 is rotated backward for adjustment, the sliding block 41 of the connecting rod 40 slides from the first end to the second end in the sliding groove 331. During the sliding process, the connecting rod 40 can drive the rear end of the side connecting plate 33 of the lifting frame assembly 30 to be slightly lifted upward. Figures 7 to 8 As shown, when the sliding block 41 of the connecting rod 40 slides to the second end of the sliding groove 331, the sliding block 41 slides to the limit position. Then, as the backrest frame assembly 20 is rotated backward for adjustment, the sliding block 41 pulls the rear end of the side connecting plate 33 of the lifting frame assembly 30 upward. When the backrest frame assembly 20 rotates to the flattened state, the rear end of the side connecting plate 33 is lifted to the highest position. Figure 11 Combined with

[0066] shown, after the foam and the cover are provided, the rear end of the lifting pad 3 is close to the lower end of the backrest 2.

[0067] In another preferred embodiment, the sliding connection between the connecting rod 40 and the corresponding side connecting plate 33 can also be realized by a slide rail mechanism. The slide rail mechanism includes a fixed rail and a moving rail slidably disposed on the fixed rail. The fixed rail can be fixedly connected to one of the side connecting plate 33 and the connecting rod 40, and the moving rail is fixedly connected to the other of the side connecting plate 33 and the connecting rod 40.

[0068] In a specific embodiment of the present invention, as Figures 1 to 3 shown, a fixing bracket 52 is formed at the front end of the seat cushion side plate 11 of the seat cushion frame assembly 10 corresponding to the side connecting plate 33 or is connected with a fixing bracket 52; the fixing bracket 52 is hinged to the front end of the side connecting plate 33.

[0069] A connecting hole 332 is formed at the front end of the side connecting plate 33, and a communicating hole 521 is provided on the fixing bracket 52. The connecting hole 332 and the communicating hole 521 are aligned and then hinged by a bolt bushing or a rivet passing through.

[0070] The fixing bracket 52 can be a separate component and is connected to the corresponding part of the seat cushion side plate 11 of the seat cushion frame assembly 10 by welding or screws. The fixing bracket 52 can also be a part of the seat cushion side plate 11 of the seat cushion frame assembly 10, that is, integrally formed with the seat cushion side plate 11.

[0071] Furthermore, a fixing bracket 52 is provided between the side connecting plate 33 and the seat cushion side plate 11 to realize the connection. The setting of the fixing bracket 52 enables a gap to be formed between the side connecting plate 33 and the seat cushion side plate 11 to place the connecting rod 40.

[0072] Preferably, as Figures 1 to 3 shown, the seat cushion frame assembly 10 further includes a rear tube 12 supported and connected to the rear end of the seat cushion side plate 11. Combining Figure 10 shown, making a seat cushion foam and a seat cushion cover on the seat cushion frame assembly 10 forms the seat cushion 1. An accommodation groove is formed inside the formed seat cushion 1 to accommodate the lifting pad 3 formed by the lifting frame assembly 30.

[0073] The lower part of the lower support plate 211 of the backrest frame assembly 20 is rotatably connected to the rear end of the seat cushion side plate 11. The lower support plate 211 of the backrest frame assembly 20 rotates by the drive of the provided drive mechanism 26. The drive mechanism 26 includes a drive motor 261 and an angle adjuster 262. The angle adjuster 262 is connected to the lower support plate 211, and the fixed disk of the angle adjuster 262 is connected to the seat cushion side plate 11. The lower support plate 211 is rotatably connected to the seat cushion side plate 11 through the angle adjuster 262. The drive motor 261 is drivingly connected to the angle adjuster 262 and can drive the angle adjuster 262 to rotate. Further, the angle adjuster 262 drives the lower support plate 211 to rotate together. The angle adjusters 262 between the two lower support plates 211 are drivingly connected through a synchronizing rod, so that the two angle adjusters 262 can rotate synchronously.

[0074] When a rear tube 12 is provided at the rear part of the seat cushion frame assembly 10, the connecting rod 40 passes over the rear tube 12, and the end of the connecting rod 40 close to the lifting frame assembly 30 is bent downward and then slidably connected to the lifting frame assembly 30.

[0075] Furthermore, the lifting frame assembly 30 further includes a support tube 34 supported and connected to the rear ends of the two side connecting plates 33. A suspension member 60 is also hung on the support tube 34. Figure 10 As shown, a lifting foam and a lifting cover are made on the lifting frame assembly 30, and then the lifting pad 3 is formed.
