Description

Technical Field

[0001] This utility model belongs to the field of automotive seat technology, and in particular relates to a reclining chair in which the back of the front seat is folded down to the height of the seat cushion. Background Technology

[0002] With the increasing prevalence of cars in daily life, they have become an important means of transportation. Car seats are a crucial component of cars, affecting both passenger comfort and safety.

[0003] In traditional cars, the front seats cannot be folded back to be flush with the seat cushion at the same height, making it impossible to lie down comfortably when resting, as the lower back is always pushed up by the bulge. Therefore, this utility model proposes a reclining chair in which the backrest of the front seat is folded back to be flush with the seat cushion height to solve the above problems. Utility Model Content

[0004] This invention provides a reclining chair where the backrest of the front seat folds down to the height of the seat cushion, aiming to solve the problems mentioned in the background art.

[0005] This utility model is implemented as follows: a reclining chair with the backrest of the front seat folding down to the height of the seat cushion, including a front link, a rear link, a seat cushion support, an angle adjuster, a backrest side panel, a seat cushion lifting motor, and a backrest angle adjustment motor.

[0006] One end of the front link is rotatably connected to the seat base, and the other end is rotatably connected to the seat cushion support. One end of the rear link is rotatably connected to the seat base, and the other end is rotatably connected to the seat cushion support. The front link and the rear link are distributed opposite to each other.

[0007] The seat cushion support and the backrest side panel are rotatably connected. The angle adjuster is located on the backrest side panel and connected to the seat back. The seat cushion lifting motor is located on the outer support plate of the seat cushion support and meshes with the rear linkage gear. The backrest angle adjustment motor is located on the backrest side panel and connected to the angle adjuster.

[0008] Preferably, the seat also includes a one-button control located on the outer wall of the seat cushion. The one-button control is used to control the seat cushion lifting motor and the backrest angle adjustment motor.

[0009] Preferably, there are two front linkages, which are distributed opposite to each other on the left and right sides of the seat.

[0010] Preferably, there are two rear linkages, which are distributed opposite to each other on the left and right sides of the seat.

[0011] Preferably, when the seat cushion needs to be adjusted to a horizontal position, the seat cushion lifting motor starts and drives the rear linkage to rotate upward, thereby driving the seat cushion support to move upward, which in turn drives the front linkage to rotate upward, and stops when the seat cushion surface reaches a horizontal position.

[0012] Preferably, when it is necessary to adjust the seat back to a horizontal position, the backrest angle adjustment motor starts and drives the angle adjuster to rotate backward, thereby driving the seat back to rotate backward. When the seat back is rotated to a horizontal position, it stops, at which point the seat back and seat cushion are aligned.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. When the seat cushion needs to be adjusted to a horizontal position, the seat cushion lifting motor starts (rotates forward), driving the rear linkage upward, which in turn moves the seat cushion support upward, and then drives the front linkage upward. The movement stops when the seat cushion surface reaches a horizontal position. After the seat cushion is adjusted to a horizontal position, when the seat back needs to be adjusted to a horizontal position, the backrest angle adjustment motor starts (rotates forward), driving the angle adjuster to rotate backward, which in turn rotates the seat back backward. The movement stops when the seat back flips to a horizontal position, at which point the seat back and seat cushion are flush, allowing for comfortable reclining.

[0015] 2. During the return to center position, the seat lifting motor starts (reverses) and drives the rear linkage downwards, which in turn moves the seat support downwards, causing the front linkage to rotate downwards. The position stops when the seat surface reaches the seating position (see Appendix 1 and Appendix 2). Figure 2 Then, the backrest angle adjustment motor starts (reverses) and drives the adjuster forward, thereby causing the seat back to rotate forward. It stops when the seat back is flipped to the sitting position (see Appendix 1 and Appendix 2). Figure 2 This allows the seat to return to its original position. Attached Figure Description

[0031] In this embodiment, when the seat cushion needs to be adjusted to a horizontal position, the seat cushion lifting motor 6 starts (rotates forward) and drives the rear linkage 2 to rotate upward, thereby driving the seat cushion support 3 to move upward, and then driving the front linkage 1 to rotate upward. The movement stops when the seat cushion surface reaches a horizontal position.

[0032] After the seat cushion is adjusted to a horizontal position, when the seat back needs to be adjusted to a horizontal position, the backrest angle adjustment motor 7 starts (rotates forward) and drives the angle adjuster 4 to rotate backward, thereby driving the seat back to rotate backward. When the seat back is rotated to a horizontal position, it stops. At this time, the seat back and seat cushion are flush, which satisfies the need for comfortable reclining.

[0033] During the return to position, the seat lifting motor 6 starts (reverses) and drives the rear linkage 2 to rotate downwards, thereby causing the seat support 3 to move downwards, which in turn causes the front linkage 1 to rotate downwards. The seat stops when the surface of the seat reaches the sitting position (see Appendix 1 and Appendix 2). Figure 2 Then, the backrest angle adjustment motor 7 starts (reverses) and drives the angle adjuster 4 to rotate forward, thereby causing the seat backrest to rotate forward. It stops when the seat backrest is flipped to the sitting position (see Appendix 1 and Appendix 2). Figure 2 This allows the seat to return to its original position;

[0034] A one-button 8 is provided, which is used to control the forward and reverse rotation of the seat cushion lifting motor 6 and the backrest angle adjustment motor 7, making adjustment convenient and quick.

[0036] In this embodiment, a one-button 8 is provided, which is used to control the forward and reverse rotation of the seat cushion lifting motor 6 and the backrest angle adjustment motor 7, making adjustment convenient and quick.

[0037] For further details, please refer to Figure 1 There are two front linkages 1, which are distributed on the left and right sides of the seat.

[0038] For further details, please refer to Figure 1 There are two rear linkages 2, which are distributed on the left and right sides of the seat.

[0039] In this embodiment, the two front links 1 and the two rear links 2, which are distributed opposite to each other on the left and right sides of the seat, are arranged in a matrix to increase the stability of the seat cushion.

[0040] The working principle and usage process of this utility model: When it is necessary to adjust the seat cushion to a horizontal position, the seat cushion lifting motor 6 starts (rotates forward) and drives the rear connecting rod 2 to rotate upward, thereby driving the seat cushion support 3 to move upward, and then driving the front connecting rod 1 to rotate upward. It stops when the surface of the seat cushion reaches a horizontal position.

[0041] After the seat cushion is adjusted to a horizontal position, when it is necessary to adjust the seat back to a horizontal position, the backrest angle adjustment motor 7 starts (rotates forward) and drives the angle adjuster 4 to rotate backward, thereby driving the seat back to rotate backward. When the seat back is rotated to a horizontal position, it stops, at which point the seat back and seat cushion are aligned.

[0042] During the return to position, the seat lifting motor 6 starts (reverses) and drives the rear linkage 2 to rotate downwards, thereby causing the seat support 3 to move downwards, which in turn causes the front linkage 1 to rotate downwards. The seat stops when the surface of the seat reaches the sitting position (see Appendix 1 and Appendix 2). Figure 2 Then, the backrest angle adjustment motor 7 starts (reverses) and drives the angle adjuster 4 to rotate forward, thereby causing the seat backrest to rotate forward. It stops when the seat backrest is flipped to the sitting position (see Appendix 1 and Appendix 2). Figure 2 This allows the seat to return to its original position.

[0043] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
