Detailed Implementation

[0056] To make the objectives, technical solutions, and advantages of this disclosure clearer, the following detailed description is provided in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are merely illustrative and do not limit the scope of protection of this disclosure.

[0057] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of this disclosure.

[0058] The seat of this disclosure will now be described in detail with reference to the accompanying drawings. Unless otherwise specified, the features of the following embodiments and implementations can be combined with each other.

[0059] In one embodiment of this disclosure, reference is made to Figures 1 to 4As shown, a seat 1 is provided, including a seat cushion 11, a backrest 12, a backrest support 13, and a backrest sliding portion 14. The seat cushion 11 extends along a first direction x. The backrest 12 is separately disposed from the seat cushion 11. The backrest support 13 extends along a second direction z and is connected to the backrest 12, the second direction z intersecting the first direction x. The backrest support 13 is slidably connected to the backrest sliding portion 14 along the first direction x.

[0060] The backrest 12 and the seat cushion 11 are separate, allowing the backrest 12 to move freely relative to it along a first direction x. When the backrest 12 moves to one end of the seat cushion 11 in the first direction x, the user sits on the seat 1 facing one direction. When the backrest 12 moves to the other end of the seat cushion 11 in the first direction x, the user sits on the seat 1 facing the opposite direction. The backrest support 13 moves relative to the backrest sliding part 14 along the first direction x, thereby driving the backrest support 13 to move along the first direction x. In this way, the direction the user faces while sitting on the seat 1 can be changed simply by moving the backrest 12 linearly. Compared to adding a rotating structure to the seat, the seat moving structure disclosed herein is simpler, more reliable, and can reduce costs.

[0061] In this embodiment, the first direction x and the second direction z are perpendicular to each other. The first direction x is set as a horizontal front-to-back direction, and the second direction z is set as a vertical up-and-down direction. (Refer to...) Figure 3 and Figure 4 As shown, when the backrest 12 moves to the rear end of the seat cushion 11 in the first direction x, the user sits on the seat 1 facing forward. When the backrest 12 moves to the front end of the seat cushion 11 in the first direction x, the user sits on the seat 1 facing backward.

[0062] The user sits on the seat cushion 11 and leans against the backrest 12.

[0063] In some embodiments, refer to Figure 1 As shown, the backrest support 13 is connected to two opposite sides of the backrest 12 in the third direction y. The third direction y intersects with the second direction z and the first direction x. In this embodiment, the third direction y is perpendicular to the plane xoz and is set as a horizontal left-right direction. The backrest support 13 is connected to at least one of the left side 121 and the right side 122 of the backrest 12. Preferably, the backrest support 13 is symmetrically arranged on the left side 121 and the right side 122 of the backrest 12 to provide stable support for the backrest 12.

[0064] In some embodiments, the backrest sliding part 14 adopts an electric slide rail and is located below the backrest 12 and the seat cushion part 11. The backrest support part 13 is located closer to the bottom of the backrest 12 than the top of the backrest 12, so as to reduce the extension length of the backrest support part 13 in the second direction z, which can both enhance the structural stability of the seat 1 and reduce costs.

[0065] In some embodiments, refer to Figures 1 to 4 As shown, the backrest 12 is rotatably connected to the backrest support 13 about a third direction y. This allows adjustment of the angle α between the backrest 12 and the seat cushion 11 to meet user needs. For example, when the user needs to sit upright, the angle α can be adjusted to approximately 90° by rotating the backrest 12. When the user needs to relax, the angle α can be adjusted to approximately 180°.

[0066] Specifically, refer to Figure 5 As shown, the seat 1 includes a backrest rotating part 15, a backrest 12 connected to the backrest rotating part 15, and a backrest supporting part 13 rotatably connected to the backrest rotating part 15. The rotation of the backrest rotating part 15 causes the backrest 12 to rotate about a third direction y.

[0067] Preferably, in this embodiment, the backrest rotating part 15 is an electric rotating shaft, and the backrest rotating part 15 passes through the backrest back 12 and the backrest support part 13 along the third direction y. The connection between the backrest rotating part 15 and the backrest support part 13 is located near the top end of the backrest support part 13.

[0068] In some embodiments, refer to Figure 3 and Figure 4 As shown, the backrest 12 is configured to have a variable height along the second direction z. This allows adjustment of the height value of the backrest 12 in the second direction z, improving the user experience.

[0069] Specifically, refer to Figure 3 and Figure 5 As shown, the backrest support 13 includes a first support 131 and a second support 132. The first support 131 is connected to the backrest sliding part 14, and the second support 132 is slidably connected to the first support 131 along the second direction z. The second support 132 is connected to the backrest 12. The second support 132 can reciprocate in the second direction z towards the first support 131 and away from the first support 131, changing the length of the backrest support 13 in the second direction z, thereby adjusting the height of the backrest 12 in the second direction z.

[0070] In this embodiment, the first support portion 131 is provided with a sliding groove 1311 extending along the second direction z, and the second support portion 132 is slidably disposed within the sliding groove 1311. The backrest rotating portion 15 is connected to the second support portion 132, and the connection point is disposed near the top end of the second support portion 132. The backrest support portion 13 includes two sets of first support portions 131 and second support portions 132, symmetrically disposed on the left side 121 and right side 122 of the backrest back 12. The top end of the second support portion 132 is arc-shaped.

[0071] Furthermore, in some embodiments, reference is made to Figure 5 and Figure 6 As shown, the backrest support 13 includes a gear 133 and a motor 134 disposed on the first support 131, and a rack 135 disposed on the second support 132.

The motor 134 drives the gear 133 to rotate, and the gear 133 drives the rack 135 to move along the second direction z, thereby driving the backrest 12 to move along the second direction z. The motor 134 and the gear 133 are fixedly disposed on the first support 131, and their positions in the second direction z remain fixed. When the gear 133 rotates, the rack 135 meshing with the gear 133 moves up and down along the second direction z, thereby pushing the second support 132 to move up and down.

[0072] In this embodiment, the rack 135 is disposed at at least one of the two ends of the second support portion 132 in the first direction x. The motor 134 and the gear 133 are disposed around the sliding groove 1311 corresponding to the rack 135.

[0073] Furthermore, referring to Figure 5 As shown, the backrest support 13 includes a reinforcing member 136 extending along a first direction x and a supporting member 137 extending along a second direction z. The reinforcing member 136 is slidably connected to the backrest sliding portion 14, and the supporting member 137 is connected to the backrest back 12. This increases the strength of the backrest support 13.

[0074] In this embodiment, the reinforcing member 136 and the supporting member 137 are interconnected to form a T-shaped structure. The length of the reinforcing member 136 in the first direction x, the width of the supporting member 137 in the first direction x, and the thickness of the reinforcing member 136 and the supporting member 137 in the third direction y are designed according to the actual required structural strength.

[0075] In some embodiments, refer to Figure 5As shown, the backrest 12 includes a backrest body 123 and a headrest portion 124, the headrest portion 124 being rotatably connected to one end of the backrest body 123 about a third direction y. This allows adjustment of the angle β between the headrest portion 124 and the backrest body 123 to meet user needs. The headrest portion 124 is located at the top of the backrest 12.

[0076] Specifically, continue to refer to Figure 5 As shown, the backrest 12 includes a headrest rotating part 125, a headrest part 124 and the headrest rotating part 125 are connected, and the headrest rotating part 125 and the backrest body 123 are rotatably connected. By rotating the headrest rotating part 125, the headrest part 124 is driven to rotate about a third direction y.

[0077] Preferably, in this embodiment, the headrest rotating part 125 is an electric rotating shaft, and the headrest rotating part 125 passes through the backrest body 123 along the third direction y. The backrest 12 also includes a support body 126, and the top end of the backrest body 123 is provided with a groove 1231. The support body 126 passes through the groove 1231 and is used to connect the headrest rotating part 125 and the headrest part 124.

[0078] In some embodiments, refer to Figure 3 and Figure 5 As shown, the seat 1 also includes a seat cushion sliding part 16 and a seat cushion support part 17, the seat cushion support part 17 being slidably connected to the seat cushion sliding part 16 along the first direction x. In this way, the position of the seat cushion sliding part 16 in the first direction x can be adjusted to meet the user's usage needs.

[0079] The seat cushion sliding part 16 may also be an electric slide rail, located below the backrest 12 and the seat cushion part 11. The seat cushion support part 17 is located at the bottom of the seat cushion part 11.

[0080] In this embodiment, both the backrest sliding part 14 and the seat cushion sliding part 16 adopt two electric slide rails extending along the first direction x, and the seat cushion sliding part 16 is disposed between the backrest sliding parts 14.

[0081] In some embodiments, refer to Figure 1 As shown, the backrest 12 includes two opposing surfaces along the first direction x: surface 127 and surface 128, which are symmetrically arranged. In some embodiments, the seat cushion 11 is symmetrically arranged along the central axis w. Thus, regardless of whether the backrest 12 moves to the front or rear of the seat cushion 11, the user can obtain the same seating comfort whether sitting forward or backward.

[0082] In some embodiments, the seat 1 also includes two seat belts (not shown), one of which is located on the surface 127 and the other on the surface 128. This allows the user to fasten the seat belts whether sitting forward or backward, ensuring full safety.

[0083] In practical applications, seat 1 includes sitting and lying postures.

[0084] In a seated position, refer to Figure 3 As shown, the seat cushion 11 includes a first end 111 and a second end 112 disposed opposite to each other in the first direction x. The backrest 12 is disposed close to the first end 111 or the second end 112, and the included angle α between the backrest 12 and the seat cushion 11 is 60° to 120°. In this way, the user can sit upright on the seat 1.

[0085] To achieve the desired sitting posture for seat 1, first adjust the fore-and-aft and up-and-down positions of the backrest 12. If the user is small, adjust the backrest 12 until it is flush against the first end 111 or the second end 112. If the user is large, adjust the backrest 12 so that it is spaced apart from the seat cushion 11 in the first x-direction and the second z-direction. Then rotate the backrest 12 to adjust the included angle α to between 60° and 120°.

[0086] In a supine position, refer to Figure 7 As shown, the connection between the backrest 12 and the backrest support 13 is not higher than the upper surface of the seat cushion 11, and the included angle α between the backrest 12 and the seat cushion 11 is 150° to 210°. In this way, the user can comfortably recline or lie flat on the seat 1.

[0087] To achieve a reclining position for seat 1, first adjust the fore-and-aft and / or up-and-down position of the backrest 12 to allow for rotation and prevent interference with the seat cushion 11. Then rotate the backrest 12 and adjust the included angle α to between 150° and 210°. Next, adjust the up-and-down position of the backrest 12 so that the connection between the backrest 12 and the backrest support 13 is not higher than the upper surface of the seat cushion 11, facilitating the user's reclining. Preferably, adjust the included angle α to 180° and adjust the backrest 12 up and down until the surface 127 or 128 of the backrest 12 is flush with the upper surface of the seat cushion 11. Finally, the fore-and-aft position of the backrest 12 can be adjusted as needed to change the distance between the backrest 12 and the seat cushion 11.

[0088] Furthermore, referring to Figure 8 As shown, in a supine position, the included angle β between the headrest 124 and the backrest body 123 is 240° to 330°. Thus, the headrest 124 and the backrest support 13 together provide support for the near-horizontal backrest body 123, making the structure more stable and reliable.

[0089] In related technologies, the connection between the backrest and seat cushion in the chair has structural limitations, making it difficult for the backrest to rotate to a horizontal position, and there is always a depression at the connection between the backrest and seat cushion, making it difficult for the user to have a comfortable experience. The chair 1 provided in this disclosure overcomes the above-mentioned defects.

[0090] In another embodiment of this disclosure, reference is made to Figures 9 to 16 As shown, a modular seat 2 is also provided, including a first seat 10 and a second seat 20, wherein the first seat 10 and the second seat 20 are the seats 1 in any of the above embodiments. The first seat 10 and the second seat 20 are arranged sequentially along a first direction x. The cushion portion 11 of the first seat 10 includes a first end 111 and a second end 112 disposed opposite to each other in the first direction x, and the cushion portion 21 of the second seat 20 includes a third end 211 and a fourth end 212 disposed opposite to each other in the first direction x. The first end 111 is disposed away from the second seat 20, the second end 112 is disposed close to the second seat 20, the third end 211 is disposed close to the first seat 10, and the fourth end 212 is disposed away from the first seat 10.

[0091] By combining and setting up the seats 1, and adjusting the cushion 11, backrest 12, and headrest 124 of the first seat 10 and the cushion 21, backrest 22, and headrest 224 of the second seat 20, multiple modes can be achieved, which are suitable for different usage scenarios.

[0092] In this embodiment, the first seat 10 and the second seat 20 share the backrest sliding part 14 and the seat cushion sliding part 16.

[0093] In some embodiments, the modular seat 2 includes a driving mode (not shown), in which the backrest 12 of the first seat 10 is positioned near the second end 112, and the backrest 22 of the second seat 20 is positioned near the fourth end 212. Thus, both the user sitting in the first seat 10 and the user sitting in the second seat 20 face the same direction.

[0094] In some embodiments, refer to Figure 9 and Figure 10 As shown, the modular seat 2 includes a communication mode. In this mode, the backrest 12 of the first seat 10 is positioned near the first end 111, and the backrest 22 of the second seat 20 is positioned near the fourth end 212. Thus, the user sitting in the first seat 10 and the user sitting in the second seat 20 can sit facing each other and interact.

[0095] Both the driving mode and the communication mode of the combination seat 2 can be achieved by changing the position of the backrest 12 and / or the backrest 22 in the first direction x. In both driving and communication modes, the first seat 10 and the second seat 20 can be adjusted to a sitting posture. One user sits on the seat cushion 11 and leans against the backrest 12, while another user sits on the seat cushion 21 and leans against the backrest 22.

[0096] In some embodiments, refer to Figure 11 and Figure 12As shown, the modular seat 2 includes a relaxation mode. In this mode, the backrest 12 of the first seat 10 is positioned near the first end 111, and the backrest 22 of the second seat 20 is positioned near the second end 112. Thus, the backrest 12 of the first seat 10, the seat cushion 11, and the backrest 22 of the second seat 20 combine to form a recliner-like seat. One of the backrests 12 and 22 serves as a backrest, and the other as leg support, allowing the user to achieve a more relaxed and comfortable seating experience in this mode.

[0097] Furthermore, the angle α2 between the backrest 12 of the first seat 10 and the backrest 22 of the second seat 20 and the seat cushion 11 of the first seat 10 is 90° to 180°, and the angle α1 between the other and the seat cushion 11 of the first seat 10 is 180° to 270°. The user's back rests against the former, and the user's legs are supported by the latter.

[0098] Furthermore, the backrest 12, which forms an angle of 180° to 270° with the seat cushion 11, includes a backrest body 123 and a headrest 124. The headrest 124 is rotatably connected to one end of the backrest body 123 about a third direction y, and the angle β between the headrest 124 and the backrest body 123 is 90° to 180°. Thus, the headrest 124 serves as a footrest, on which the user places their feet.

[0099] Understandably, the relaxation mode can also be configured such that the backrest 12 of the first seat 10 is positioned near the third end 211, and the backrest 22 of the second seat 20 is positioned near the fourth end 212.

[0100] In order to achieve the relaxation mode of the combination seat 2, the backrest 12 and backrest 22 can be moved along the first direction x respectively, and then the backrest 12, backrest 22, headrest 124 and headrest 224 can be rotated.

[0101] In some embodiments, refer to Figure 13 and Figure 14 As shown, the modular seat 2 includes a sleep mode. In sleep mode, the backrest 12 of the first seat 10 is positioned near the first end 111. The backrest 22 of the second seat 20 is positioned near the fourth end 212. The seat cushion 11 of the first seat 10 and the seat cushion 21 of the second seat 20 abut against each other along a first direction x. Combining the first seat 10 and the second seat 20 provides a longer, bed-like seat, allowing the user to lie completely flat and get sufficient rest.

[0102] In sleep mode, one of the first seat 10 and the second seat 20 can be adjusted to a sitting position, and the other to a reclining position. Alternatively, both the first seat 10 and the second seat 20 can be adjusted to a reclining position.

[0103] In some embodiments, refer to Figure 15 and Figure 16 As shown, the modular seating 2 includes a tea break mode. In tea break mode, the modular seating 2 comprises two sets of seats, a first seat 10 and a second seat 20, in a relaxed state. The two sets of seats are arranged at intervals in the third direction y. The arrangement order of the first seat 10 and second seat 20 in one set in the first direction x is the opposite of that in the other set. Thus, one user sits in one set of seats, and another user sits in the other set, allowing the two users to interact diagonally in the relaxed state.

[0104] Furthermore, the cushion portion 21 of the second seat 20 in one group is aligned with the cushion portion 11 of the first seat 10 in the other group in the third direction y. In this way, the extra cushion portion 21 of one group of seats can be used as a coffee table for the user sitting on the other group of seats, for placing items such as snacks, mobile phones, and iPads.

[0105] In another embodiment of this disclosure, a vehicle (not shown) is also provided, including the seat 1 and vehicle body (not shown) as described in any of the above embodiments. The seat 1 is disposed within the vehicle body, and the backrest sliding portion 14 is disposed at the bottom of the vehicle body. The seat 1 is disposed within the vehicle body, allowing users to adjust the seat according to their needs and obtain a better riding experience. Furthermore, the seat 1 requires little space to change its direction, thus improving the space utilization within the vehicle body.

[0106] Understandably, the seat cushion sliding part 16 is also located at the bottom of the vehicle body.

[0107] Specifically, the backrest sliding part 14 and the seat cushion sliding part 16 are embedded in the bottom of the vehicle body, and the openings are covered with materials such as nylon and fabric to prevent dust from entering the backrest sliding part 14 and the seat cushion sliding part 16. Furthermore, the reinforcing member 136 of the backrest support part 13 is also embedded in the bottom of the vehicle body to prevent passengers from bumping into it.
