[0043] The embodiments of the present invention are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. Figure 1-Figure 12 A seat 100 according to an embodiment of the present invention is described. The seat 100 includes a slide rail 10 , a seat cushion 20 and a backrest 30 .

[0044] Specifically, if Figure 1-Figure 11 As shown, the seat cushion 20 can slide relative to the slide rail 10 along the first direction A, the seat cushion 20 can be turned around the second direction C, and the backrest 30 can slide relative to the slide rail 10 along the first direction A, and the backrest 30 can be turned around the second direction C. The seat cushion 20 includes a first surface 21, and the first surface 21 is opposite to the use surface of the seat cushion 20 in the sitting state. In this embodiment, the use surface of the seat cushion 20 in the sitting state is the third surface 22. The backrest 30 includes a second surface 31, and the second surface 31 is opposite to the use surface of the backrest 30 in the sitting state, and the use surface of the backrest 30 in the sitting state is the fourth surface 32.

[0045] The seat 100 has a first non-sitting state, in which the first surface 21 is located on a side of the seat cushion 20 away from the slide rail 10 along the third direction B, and the second surface 31 is located on a side of the backrest 30 away from the slide rail 10 along the third direction B, wherein the first direction A is the length direction of the slide rail 10, and the first direction A, the second direction C and the third direction B are orthogonal. In the first surface 21 perpendicular to the third direction B, the projection of the seat cushion 20 does not overlap with the projection of the backrest 30.

[0046] The seat cushion 20 and the backrest 30 are two independent parts. The seat cushion 20 and the backrest 30 are independently matched with the slide rail 10. The seat cushion 20 and the backrest 30 can be independently moved relative to the slide rail 10 along the first direction A, wherein the first direction A is the movement direction of the slide rail 10. The seat cushion 20 and the backrest 30 can be independently flipped relative to the slide rail 10 in the second direction C so that the seat cushion 20 and the backrest 30 are laid flat. When the seat 100 is in the first non-sitting state, the first surface 21 of the seat cushion 20 and the second surface 31 of the backrest 30 are respectively located on the side of the seat cushion 20 and the backrest 30 away from the slide rail 10 along the third direction B. At this time, the orthographic projections of the first surface 21 and the second surface 31 in the third direction B do not overlap, and the seat 100 is in a completely flat state. The movement of the seat cushion 20 and the backrest 30 along the first direction A can avoid the interference of the backrest 30 when the seat cushion 20 rotates, or the interference of the backrest 30 when the seat cushion 20 rotates.

[0047] According to the seat 100 of the embodiment of the utility model, the seat cushion 20 and the backrest 30 can be completely laid flat by independently moving the seat cushion 20 and the backrest 30 relative to the slide rail 10, so as to avoid the problem that the backrest 30 cannot be completely laid flat when it is flipped and placed on the seat cushion 20, so as to further reduce the space occupied by the seat 100 and release more space. At the same time, since the seat cushion 20 and the backrest 30 move and rotate independently, the seat 100 can selectively lay one or both of the seat cushion 20 and the backrest 30 flat according to the use requirements, so as to provide users with more choices and enhance the user experience.

[0048] In some embodiments, Figure 8 As shown, in the first non-sitting state, the seat cushion 20 moves in the first direction A toward the direction away from the backrest 30, and flips forward at a predetermined angle α1 around the second direction C, and the backrest 30 flips toward the seat cushion 20 at a predetermined angle β1 around the second direction C. That is, when the backrest 30 of the seat 100 needs to be stored, the seat cushion 20 can be moved in the direction away from the backrest 30 for a certain distance and then flipped toward the seat cushion 20, so that the use surface of the backrest 30 contacts the use surface of the seat cushion 20. Therefore, in the first non-sitting state, the utilization rate of the space above the seat 100 can be increased to meet more diverse usage requirements.

[0049] Optionally, in the first non-sitting state, the backrest 30 moves along the first direction A in a direction away from the seat cushion 20, and flips forward by a predetermined angle β2 around the second direction C, and the seat cushion 20 flips by a preset angle α2 around the second direction C in a direction away from the backrest 30. That is, when it is necessary to store the backrest 30 of the seat 100, the backrest 30 of the seat 100 can be slid first so that the backrest 30 of the seat 100 slides a certain distance in a direction away from the seat cushion 20, and then the seat cushion 20 and the backrest 30 are flipped. For example, when all seats 100 are in the first non-sitting state, a plane is formed, which can provide users with sleeping space in the car and give them a big bed-like experience. Thereby, it is convenient to realize the flat folding of the seat 100, maximize the utilization of space, and improve the user experience. α1 and α2 can be any values ​​within 0-180°. β1 and β2 can be any values ​​within 0-180°. In some embodiments, such as Figure 1As shown, the use surface of the seat cushion 20 in the sitting state, that is, the surface on which the user sits, is the third surface 22. In the sitting state, the first surface 21 and the third surface 22 are opposite to each other along the third direction B, that is, in the sitting state, the first surface 21 and the third surface 22 of the seat cushion 20 are respectively located on both sides of the seat cushion 20 along the third direction B. Among them, the first surface 21 is formed as a plane. Compared with the use surface of the seat cushion 20, the use surface that contacts the user's body generally conforms to the ergonomic design to increase the comfort and wrapping of the ride. The first surface 21 is a flat design to ensure that a relatively regular space can be provided when the seat cushion 20 is flipped, thereby improving the space utilization rate.

[0050] The use surface of the backrest 30 in the sitting state, that is, the surface of the backrest 30 when the user sits, is the fourth surface 32. In the sitting state, the second surface 31 and the fourth surface 32 of the backrest 30 are opposite along the first direction A, that is, in the sitting state, the second surface 31 and the fourth surface 32 of the backrest 30 are respectively located on both sides of the backrest 30 along the first direction A. Among them, the second surface 31 is formed as a plane. In the sitting state, the third surface 22 of the seat cushion 20 and the fourth surface 32 of the backrest 30 are adjacent to each other. At this time, the seat 100 is used for the normal sitting of the user and provides support for the user. Here, the second surface 31 of the backrest 30 is a plane, which is also relative to the use surface. The use surface needs to contact with the user to increase the comfort and reliability of the ride, which is in line with the reality of ergonomics. However, when the backrest 30 is flipped and the utilization rate of the space needs to be increased, the second surface 31 is a plane design to release more space.

[0051] In some embodiments, Figure 4 As shown, when the seat 100 is in the first non-sitting state, the first surface 21 is located on the side of the seat cushion 20 away from the slide rail 10 along the third direction B, the second surface 31 is located on the side of the backrest 30 away from the slide rail 10 along the third direction B, and the ends of the seat cushion 20 and the backrest 30 adjacent to each other are in contact with each other. For example, when it is necessary to further utilize the space, the seat cushion 20 can be flipped forward 180°, and the backrest 30 can be flipped forward 0-180°, so that the first surface 21 and the second surface 31 are respectively located on the side away from the slide rail 10, the ends of the seat cushion 20 and the backrest 30 adjacent to each other are stopped along the first direction A, and the projections of the backrest 30 and the seat cushion 20 along the third direction B do not overlap, so that the surfaces of the flipped seat cushion 20 and the backrest 30 can be completely flat.

[0052] In some embodiments, Figure 6As shown, the seat 100 has a second non-sitting state. When the seat 100 is in the second non-sitting state, the seat cushion 20 and the backrest 30 are stacked along the first direction A, and the use surface of the backrest 30 in the riding state, that is, the fourth surface 32, contacts the first surface 21. That is, the seat cushion 20 and the backrest 30 are both moved to one end of the slide rail 10 along the first direction A. At this time, the seat cushion 20 and the backrest 30 are both turned around the second direction C by a certain angle so that the second surface 31 of the backrest 30 contacts the fourth surface 32 to achieve folding and storage of the backrest 30 and the seat cushion 20, thereby increasing the utilization rate of the space. For example, the seat cushion rotates 90° counterclockwise around the second direction C, and the backrest moves along the first direction A toward the rotated seat cushion to achieve folding of the seat cushion and the backrest.

[0053] In some embodiments, in combination Figure 6 In the second non-sitting state, the seat cushion 20 moves along the first direction A in a direction away from the backrest 30, and the seat cushion 20 rotates around the second direction C by a preset angle α3, and the backrest 30 moves along the first direction A to contact the seat cushion 20, and the angle of rotation of the backrest 30 around the second direction is β3. In this state, after the seat cushion 20 flips around the second direction C by an angle α3, the backrest 30 flips around the second direction C toward the seat cushion 20 by a certain angle β3, and α3 and β3 can be any angle within 0-90°, so that the first surface 21 of the seat cushion 20 contacts the use surface of the backrest 30. When the seat 100 is in the second non-sitting state, multiple seats 100 can be stored and stacked along the first direction A, thereby increasing the utilization of the space in the first direction A.

[0054] Alternatively, if Figure 2 and Figure 3As shown, the seat 100 has a third non-sitting state. When the seat 100 is in the third non-sitting state, the backrest 30 is flipped around the second direction C toward the seat cushion 20 by a preset angle β4, and the use surface of the backrest 30 contacts the use surface of the seat cushion 20. That is, when the seat 100 needs to be in the third non-sitting state, the backrest 30 can be flipped around the second direction C toward the seat cushion 20 so that the use surface of the backrest 30 and the use surface of the seat cushion 20 are opposite and contacting in the third direction B. β4 can be a value within 0-90°, and in this embodiment, β4 can be 90°. When the seat 100 is in the third non-sitting state, the two ends of the seat cushion 20 and the backrest 30 are respectively opposite and contacting each other in the third direction B. The third surface 22 is located on the side of the seat cushion 20 away from the slide rail 10 along the third direction B, the second surface 31 is located on the side of the backrest 30 away from the slide rail 10 along the third direction B, and the fourth surface 32 contacts the third surface 22. That is, at this time, the seat cushion 20 remains in the sitting state, and the backrest 30 rotates toward the seat cushion 20 so that the fourth surface 32 contacts the third surface 22, so that the backrest 30 can be laid down, so that the backrest 30 is in the non-sitting state, thereby increasing the utilization of the space above the seat cushion 20. At this time, the projections of the seat cushion 20 and the backrest 30 along the third direction B at least partially overlap, and the backrest 30 is stacked above the seat cushion 20 along the third direction B.

[0055] In some embodiments, in combination Figure 5 , the seat 100 has a fourth non-sitting state. When the seat 100 is in the fourth non-sitting state, the backrest 30 rotates by a preset angle β5 around the second direction C toward a direction away from the seat cushion 20, and the seat cushion 20 rotates by a preset angle α5 around the second direction C toward a direction away from the backrest 30. That is, in the fourth non-sitting state, the seat cushion 20 can be turned over by a certain angle α5 toward a direction away from the backrest 30, and α5 can be 0-180°, and the backrest 30 can be turned over by a certain angle β5 toward a direction away from the seat cushion 20, and β5 can be 0-90°. Thus, the needs of different users can be met by adjusting the angle of the backrest 30.

[0056] Furthermore, combined with Figure 7 , only the angle of the seat cushion 20 can be adjusted according to the needs, the leg space of the user can be adjusted, and the waist support can be provided for the user to increase the riding comfort. Figure 1-Figure 8 The seats 100 are arranged in a plurality of groups along a first direction A, that is, the seats 100 are arranged at intervals along the first direction A, and can all be flipped relative to the slide rail 10. Here, the first direction A can be understood as the front-rear direction of the seats 100.

[0057] Specifically, the plurality of seats 100 includes a first seat group 101 and a second seat group 102, wherein the first seat group 101 is located in front of the second seat group 102. The plurality of seats 100 has a first combination state, that is, Figure 4 In the state shown, when the plurality of seats 100 are in the first combination state, the first seat group 101 is in the seat sitting state, and the second seat group 102 is in the first non-sitting state. In this embodiment, the user can keep the first seat group 101 in the seat sitting state according to the needs, at which time the third surface 22 is arranged away from the slide rail 10, and the fourth surface 32 is arranged toward the seat cushion 20. At the same time, the second seat group 102 is in the first non-sitting state, and the first surface 21 and the second surface 31 included in the second seat group 102 are both located on the side away from the slide rail 10.

[0058] Thus, the first group of seats 101 is in a sitting state, and the second group of seats 102 is in a first non-sitting state, that is, the seat cushion 20 of the second group of seats 102 is in a seat cushion non-sitting state, and the backrest 30 is in a backrest non-sitting state, which can increase the space behind the first group of seats 101. At the same time, since the second group of seats 102 is in the first non-sitting state, and since the side of the second group of seats 102 away from the slide rail 10 is flat, the stability of placed objects can be increased, thereby expanding the rear space of the first group of seats 101.

[0059] In some embodiments, Figure 5 As shown, the multiple groups of seats 100 include a first group of seats 101 and a second group of seats 102, and the first group of seats 101 is located in front of the second group of seats 102; the multiple groups of seats 100 have a second combination state, when the multiple groups of seats 100 are in the second combination state, the first group of seats 101 are in a first non-sitting state, the second group of seats 102 are in a second non-sitting state, the fourth surface 32 of the backrest 30 of the second group of seats 102 faces the first group of seats 101, and the seat cushion 20 of the second group of seats 102 stops between the fourth surface 32 of the backrest 30 of the first group of seats 101 and the second group of seats 102. This kind of seat 100 layout is that the seat cushion 20 of the second group of seats 102 is used as a "backrest" for the user to sit on, and the backrest 30 of the first group of seats 101 after being fully folded down is used for sitting, thereby increasing the seating area for the user, and the seat cushion 20 of the first group of seats 101 can be used to support the user's legs, and by flipping the seat cushion 20 of the second group of seats 102 and adjusting the flipping angle, different sitting postures can be obtained to adjust a more comfortable sitting posture so that the user's legs can be supported and straightened, thereby increasing the user's experience.

[0060] In some embodiments, Figure 7As shown, the multiple groups of seats 100 include a first group of seats 101 and a second group of seats 102, and the first group of seats 101 is located in front of the second group of seats 102; the multiple groups of seats 100 have a third combination state, when the multiple groups of seats 100 are in the third combination state, the first group of seats 101 are in a first non-sitting state, and the second group of seats 102 are in a fourth non-sitting state, that is, the seat cushion 20 of the second group of seats 102 is in a non-sitting state, and the fourth surface 32 of the backrest 30 of the second group of seats 102 faces the first group of seats 101, and the lower end is in contact with the seat cushion 20 of the second group of seats 102. In this layout of seats 100, the seat cushion 20 and backrest 30 included in the first group of seats 101 and the seat cushion 20 included in the second group of seats 102 are all flipped forward 180° and are in a completely flat state. The backrest 30 of the second group of seats 102 can be adjusted in angle according to the user's needs so that the user can obtain a more comfortable posture when half-lying on the seat 100. The backrest 30 of the second group of seats 102 is used to support the user's back and head.

[0061] In some embodiments, Figure 8 As shown, the multiple seats 100 include a first seat group 101 and a second seat group 102, wherein the first seat group 101 is located in front of the second seat group 102. The multiple seats 100 have a fourth combination state, when the multiple seats 100 are in the fourth combination state, both the first seat group 101 and the second seat group 102 are in a first non-sitting state, and the seat cushion 20 of the second seat group 102 abuts against the backrest 30 of the first seat group 101. That is, along the first direction A, the seat cushion 20 and the backrest 30 included in the first group of seats 101 are flipped forward, and the seat cushion 20 and the backrest 30 included in the second group of seats 102 are flipped forward, so that the first surface 21 and the second surface 31 are located on the side away from the slide rail 10, and the seat cushion 20 and the backrest 30 of the first group of seats 101 are stopped along the first direction A, and the seat cushion 20 and the backrest 30 of the second group of seats 102 are stopped along the first direction A, and the backrest 30 of the first group of seats 101 and the seat cushion 20 of the second group of seats 102 are stopped, so that the first group of seats 101 and the second group of seats 102 can be completely laid flat, eliminating the gap between the first group of seats 101 and the second group of seats 102 and the gap between the backrest 30 and the seat cushion 20 to form a regular plane, which can provide users with sleeping space to get a better user experience.

[0062] In some embodiments, in combination Fig.12The slide rail 10 includes a first slide rail and a second slide rail. The first slide rail is movably matched with the seat cushion 20; the second slide rail is movably matched with the backrest 30, and the first slide rail and the second slide rail are spaced apart along the first direction A. The backrest 30 and the seat cushion 20 are respectively matched with different slide rails 10, which is convenient for improving the flexibility of setting the slide rail 10 and reducing the cost of the slide rail 10. Optionally, the first slide rail and the second slide rail are connected, and the seat cushion 20 and the backrest 30 can move between the first slide rail and the second slide rail. In some embodiments, as Fig.10 As shown, the backrest 30 and / or the seat cushion 20 include: a first frame and a second frame, that is, the backrest 30 or the seat cushion 20 includes: a first frame and a second frame, the first frame is movably connected to the slide rail 10, and the second frame is hinged to the first frame.
