For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0022] The following is for reference. Figures 1-15 According to the embodiment of the present utility model, the seat assembly 100 can be operated by the button 5 to drive the backrest tilting mechanism 2 to tilt the backrest structure 11, drive the seat lifting mechanism 3 to lift the seat cushion structure 12, and drive the slide rail moving mechanism 4 to move the seat cushion structure 12 forward. The operation is convenient and facilitates rear passengers to enter the rear space with one button.

[0023] like Figure 1 As shown, the seat assembly 100 of this utility model embodiment includes: a seat 1, a backrest tilting mechanism 2, a seat lifting mechanism 3, a slide rail moving mechanism 4, and operation buttons 5.

[0024] Seat 1 includes a backrest structure 11 and a seat cushion structure 12. The backrest structure 11 is rotatably connected to the seat cushion structure 12, and the seat cushion structure 12 is slidably mounted on the vehicle body. That is, the backrest structure 11 can rotate relative to the seat cushion structure 12, allowing the seat cushion structure 12 to be relatively fixed to the vehicle body. The backrest structure 11 can rotate forward or backward on the seat cushion structure 12, enabling flexible adjustment of the backrest angle of seat 1. When rotating forward, it provides more space behind the backrest structure 11. Furthermore, the seat cushion structure 12 can slide relative to the vehicle body, for example, sliding forward to create a larger clearance space behind seat 1, facilitating passenger access to the rear seats. Thus, the seat cushion structure 12 can drive the backrest structure 11 to slide forward, and the backrest structure 11 can rotate forward relative to the seat cushion structure 12, thereby providing a larger clearance space behind seat 1 for quick passenger access to the rear seats.

[0025] Additionally, the backrest tilting mechanism 2 is connected to the backrest structure 11 to drive the backrest structure 11 to tilt forward and backward relative to the seat cushion structure 12, the seat lifting mechanism 3 is connected to the seat cushion structure 12 to drive the seat cushion structure 12 to rise and fall, and the slide rail moving mechanism 4 is connected to the seat cushion structure 12 to drive the seat cushion structure 12 to slide forward and backward. In other words, the backrest structure 11 can be tilted relative to the seat cushion structure 12 by the backrest tilting mechanism 2. For example, the backrest structure 11 can be tilted forward to leave space behind the seat 1, or tilted backward to restore the backrest structure 11 to its original position. The seat cushion structure 12 can be raised and lowered by the seat lifting mechanism 3. For example, the seat cushion structure 12 can be raised to drive the backrest structure 11 to rise, or the seat cushion structure 12 can be lowered to drive the backrest structure 11 to fall, thus realizing the up and down adjustment of the seat 1. The seat cushion structure 12 can also be slid back and forth relative to the vehicle body by the slide rail moving mechanism 4. For example, the seat cushion structure 12 can be slid forward, and the seat cushion structure 12 can drive the backrest structure 11 to slide forward synchronously, thus leaving space behind the seat 1, or the seat cushion structure 12 can be slid backward, and the seat cushion structure 12 can drive the backrest structure 11 to slide backward together, thus restoring the seat 1 to its original position.

[0026] The seat lifting mechanism 3 can cooperate with the slide rail moving mechanism 4 to allow the seat 1 to slide smoothly back and forth. For example, after the seat lifting mechanism 3 lifts the seat cushion structure 12 and the backrest structure 11, the slide rail moving mechanism 4 can control the seat cushion structure 12 and the backrest structure 11 to slide forward; and after the forward sliding is completed, the slide rail moving mechanism 4 can control the seat cushion structure 12 and the backrest structure 11 to slide backward, and the seat lifting mechanism 3 controls the seat cushion structure 12 and the backrest structure 11 to descend so that the seat 1 returns to its original position. Thus, the back and forth movement of the seat 1 can be controlled.

[0027] Furthermore, the operation button 5 is configured to unlock the backrest tilt mechanism 2 upon triggering, thereby driving the seat cushion structure 12 to tilt forward; unlock the seat lifting mechanism 3, thereby driving the seat cushion structure 12 to lift; and unlock the slide rail moving mechanism 4, thereby driving the seat cushion structure 12 to move forward. In other words, the operation button 5 can control the forward tilt of the backrest structure 11 and can control the forward sliding of the seat cushion structure 12 and the backrest structure 11, so that the rear of the seat 1 can reserve more clearance.

[0028] Specifically, the operation button 5 can be triggered, and then the backrest tilting mechanism 2 controls the backrest structure 11 to tilt forward on the seat cushion structure 12. The seat lifting mechanism 3 can continue to control the seat cushion structure 12 to lift the backrest structure 11 upward. After the seat cushion structure 12 is lifted, the slide rail moving mechanism 4 can drive the seat cushion structure 12 to slide the backrest structure 11 forward. Thus, the forward tilting of the backrest structure 11 and the forward sliding of the seat 1 are achieved, which allows for a larger reserved space at the rear of the seat 1, facilitating passenger access to the rear seat space.

[0029] In other words, when rear passengers enter the rear seat space, they can actively operate the operation button 5. After the operation button 5 is triggered, multiple adjustment processes can be achieved, such as tilting the backrest structure 11 forward, raising the seat cushion structure 12, and moving the seat cushion structure 12 forward. All of these adjustment processes are controlled by one button, enabling the seat 1 to avoid the rear passengers, facilitating the passengers to enter the rear seat space with one button, making the operation more convenient, reducing the difficulty of the operation for passengers to enter the rear space, and improving the passenger experience.

[0030] In the actual design, the operation button 5 can be located on the top of the seat 1, which is convenient for rear passengers to press actively. That is, passengers can reach their hands to the top of the seat 1 to press the operation button 5, making the operation more convenient.

[0031] According to the seat assembly 100 of this utility model embodiment, the backrest tilting mechanism 2, the seat lifting mechanism 3 and the slide rail moving mechanism 4 can be unlocked by operating the button 5, thereby driving the backrest structure 11 of the seat 1 to tilt forward and the backrest structure 11 and the seat cushion structure 12 to slide forward, thus reserving a larger clearance space for passengers to pass through at the rear of the seat 1, and the operation is more convenient than that of a traditional manually controlled vehicle seat 1.

[0032] In some embodiments, the seat assembly 100 further includes a control structure 6 and an unlocking mechanism 7. Both the operation button 5 and the unlocking mechanism 7 are electrically connected to the control structure 6. The control structure 6 is used to control the unlocking mechanism 7 to unlock the backrest tilting mechanism 2, the seat lifting mechanism 3, and the slide rail moving mechanism 4 after the operation button 5 is triggered. That is, the control structure 6 and the unlocking mechanism 7 enable the operation button 5 to unlock the backrest tilting mechanism 2, the seat lifting mechanism 3, and the slide rail moving mechanism 4 to drive the backrest structure 11 to tilt forward, and the backrest structure 11 and the seat cushion structure 12 to slide forward.

[0033] Specifically, such as Figure 1 As shown, the control structure 6 can be electrically connected to the operation button 5 and the unlocking mechanism 7 via wiring harnesses. After the operation button 5 is triggered, the operation button 5 can send an electrical signal to the control structure 6. The control structure 6 can analyze and judge the electrical signal and then control the unlocking mechanism 7 via the wiring harness to unlock the backrest tilting mechanism 2, the seat lifting mechanism 3, and the slide rail moving mechanism 4 respectively. This causes the backrest tilting mechanism 2 to drive the backrest structure 11 to tilt forward, the seat lifting mechanism 3 to drive the seat cushion structure 12 to lift the backrest structure 11 upward, and the slide rail moving mechanism 4 to control the seat cushion structure 12 and the backrest structure 11 to slide forward, thereby reserving sufficient clearance for the rear of the seat 1, which is conducive to passengers entering the rear space.

[0034] Therefore, the movement of seat 1 can be flexibly controlled by operating button 5, control structure 6 and unlocking mechanism 7, so as to avoid passengers behind seat 1 and facilitate the passage of passengers. Moreover, triggering operation button 5 is simple and convenient.

[0035] In some embodiments, the backrest tilting mechanism 2 includes a backrest adjustment torsion bar 21 and an angle adjuster 22. The backrest structure 11 is rotatably connected to the seat cushion structure 12 via the angle adjuster 22. The backrest adjustment torsion bar 21 is connected to the backrest structure 11. The unlocking mechanism 7 is used to unlock the angle adjuster 22. After the angle adjuster 22 is unlocked, the backrest adjustment torsion bar 21 applies a tilting torque to the backrest structure 11 to tilt the backrest structure 11 forward. That is, the backrest adjustment torsion bar 21 can apply torque to the backrest structure 11 to tilt it forward, and the angle adjuster 22 can control the unlocking of the tilting of the backrest structure 11. Flexible control of the tilting of the backrest structure 11 can be achieved through the backrest adjustment torsion bar 21 and the angle adjuster 22.

[0036] like Figure 2 , Figure 3 and Figures 5-7As shown, the left end of the backrest adjustment torsion bar 21 can be fixedly connected to the seat cushion structure 12, and the right end of the backrest adjustment torsion bar 21 can be twistedly connected to the backrest structure 11, so that the backrest adjustment torsion bar 21 can always apply a torque to the backrest structure 11 to tilt it forward relative to the seat cushion structure 12; and the angle adjuster 22 can be connected to the unlocking mechanism 7, so that when the angle adjuster 22 is unlocked, the backrest adjustment torsion bar 21 can drive the backrest structure 11 to tilt forward, and when the angle adjuster 22 is locked, the backrest structure 11 and the seat cushion structure 12 can be fixed relative to each other.

[0037] Specifically, one end of the backrest adjustment torsion rod 21 connected to the seat cushion structure 12 can be bent into a U-shaped structure and inserted into the side plate of the seat cushion structure 12 to achieve a fixed connection with the seat cushion structure 12. The other end of the backrest adjustment torsion rod 21 can be relatively fixed to the backrest structure 11 through the torsion rod pressure plate 211 and the fixing bolt 212. For example, the other end of the backrest adjustment torsion rod 21 can be set between the torsion rod pressure plate 211 and the backrest structure 11, and then the torsion rod pressure plate 211 and the backrest structure 11 can be bolted together with the fixing bolt 212, so that the other end of the backrest adjustment torsion rod 21 is relatively fixed to the backrest structure 11. At this time, the torque generated by the backrest adjustment torsion rod 21 can drive the backrest structure 11 to tilt forward.

[0038] When the adjuster 22 is unlocked, the backrest structure 11 and the seat cushion structure 12 can rotate relative to each other. At this time, the torque of the backrest adjustment torsion bar 21 can drive the backrest structure 11 to tilt forward relative to the seat cushion structure 12. When the adjuster 22 is locked, the backrest structure 11 and the seat cushion structure 12 can be relatively fixed against the torque of the backrest adjustment torsion bar 21. Therefore, the user can flexibly control the forward tilt of the backrest structure 11 through the adjuster 22, making the control of the backrest structure 11 more convenient and efficient.

[0039] The backrest adjustment torsion bar 21 can be made of metal, and the torque generated can be controlled by controlling the diameter, material, structure, etc. of the backrest adjustment torsion bar 21.

[0040] In some embodiments, the unlocking mechanism 7 includes a first unlocking motor 71 and a first unlocking cable 72. The angle adjuster 22 is provided with an angle adjuster unlocking lever 221. The first unlocking motor 71 pulls the angle adjuster unlocking lever 221 through the first unlocking cable 72 to unlock the angle adjuster 22. That is, the unlocking of the angle adjuster 22 can be controlled by the first unlocking motor 71, thereby allowing the angle adjuster 22 to be controlled by the control structure 6, making it simpler and more convenient for the user to control the tilt of the backrest structure 11.

[0041] like Figure 7 , Figure 8 , Figure 14 and Figure 15As shown, the first unlocking motor 71 can be connected to one end of the first unlocking cable 72 so that the first unlocking motor 71 can control the first unlocking cable 72, and the other end of the first unlocking cable 72 can be connected to the angle adjuster unlocking lever 221 so that the first unlocking cable 72 can pull the angle adjuster unlocking lever 221, thereby controlling the unlocking and locking of the angle adjuster 22.

[0042] Specifically, a spring can be installed between the angle adjuster unlocking lever 221 and the angle adjuster 22. The spring can pull the angle adjuster unlocking lever 221 toward the angle adjuster 22 to lock the angle adjuster 22, thereby fixing the backrest structure 11 and the seat cushion structure 12 relative to each other. When the control structure 6 controls the first unlocking motor 71 to start, the first unlocking motor 71 can drive the first unlocking cable 72 to pull the angle adjuster unlocking lever 221 to overcome the elastic force of the spring and move away from the angle adjuster 22. At this time, the angle adjuster 22 is unlocked, and the backrest structure 11 can tilt forward relative to the seat cushion structure 12. When the control structure 6 controls the first unlocking motor 71 to close, the angle adjuster unlocking lever 221 can move closer to the angle adjuster 22 under the action of the elastic force of the spring, thereby locking the angle adjuster 22. At this time, the backrest structure 11 and the seat cushion structure 12 are relatively fixed.

[0043] Therefore, the control structure 6 can flexibly control the locking and unlocking of the angle adjuster 22 through the first unlocking motor 71 and the first unlocking cable 72, making the operation simple and convenient.

[0044] And / or, in other embodiments, there are at least two adjusters 22, which are laterally spaced and connected between the backrest structure 11 and the seat cushion structure 12. That is, both adjusters 22 can control the tilt of the backrest structure 11 to achieve more stable control of the backrest structure 11.

[0045] like Figure 5 As shown, two angle adjusters 22 are located inside the connection between the backrest structure 11 and the seat cushion structure 12 on the left and right sides. The first unlocking motor 71 is connected to one end of the first unlocking cable 72, and the other end of the first unlocking cable 72 can be split into two cable branches by the cable splitter 75 to be connected to the two angle adjusters 22 respectively, so that the first unlocking motor 71 can control the two angle adjusters 22 at the same time.

[0046] Specifically, the control structure 6 can control the first unlocking motor 71 to start, and the first unlocking motor 71 can control the first unlocking cable 72 to pull the angle unlocking paddles 221 of the two angle adjusters 22 at the same time, so that the two angle adjusters 22 are unlocked at the same time, thereby allowing the backrest structure 11 to tilt relative to the seat cushion structure 12, which is conducive to more stable control of the backrest structure 11.

[0047] In some embodiments, the seat assembly 100 further includes a backrest limiting mechanism 8, which has a movable limiting adjustment piece 81, and a limiting stop piece 111 on the backrest structure 11. The unlocking mechanism 7 is used to drive the limiting adjustment piece 81 to unlock when the backrest tilting mechanism 2 is unlocked. When the limiting adjustment piece 81 is unlocked and the backrest structure 11 is tilted forward to a target angle, the limiting stop piece 111 stops and abuts against the limiting adjustment piece 81. In other words, the limiting adjustment piece 81 and the limiting stop piece 111 can limit the adjustment angle of the backrest structure 11 through mutual stopping and abutment.

[0048] like Figure 7 and Figure 8 As shown, the limiting adjustment piece 81 is rotatably connected to the backrest limiting mechanism 8, and one end of the limiting adjustment piece 81 is connected to the first unlocking cable 72. The other end of the limiting adjustment piece 81 can be connected to the backrest limiting mechanism 8 through the elastic element 812. For example, the elastic element 812 can be set as a spring. When the first unlocking motor 71 is turned on, the first unlocking cable 72 can pull the limiting adjustment piece 81 and the end connected to it to rotate around the first rotating shaft 81. At this time, the other end of the limiting adjustment piece 81 overcomes the elastic force of the elastic element 812 and moves to the movement trajectory of the limiting stop piece 111, so that when the backrest structure 11 is tilted forward, the limiting adjustment piece 81 can press against the limiting stop piece 111, so that the backrest structure 11 stops rotating after moving to the set angle.

[0049] Therefore, the rotation angle of the backrest structure 11 can be controlled by the backrest limiting mechanism 8, such as controlling the external dimensions and position of the limiting adjustment piece 81, or adjusting the forward tilt angle of the backrest structure 11 by other means.

[0050] It should be noted that one end of the first unlocking cable 72 is connected to the first unlocking motor 71, and the other end is connected to the backrest limiting mechanism 8 and the angle adjuster 22 respectively through the cable splitter 75. The cable splitter 75 can split the first unlocking cable 72 into multiple cable branches to be connected to the backrest limiting mechanism 8 and the angle adjuster 22 respectively. Moreover, the end connected to the angle adjuster 22 can be split into two cable branches through the cable splitter 75 and connected to the two angle adjusters 22.

[0051] In some embodiments, the slide rail moving mechanism 4 includes a moving rail 41 and a fixed rail 42. The fixed rail 42 is connected to the vehicle body, and the moving rail 41 is connected to the seat cushion structure 12. The moving rail 41 is slidable relative to the fixed rail 42. That is, the seat cushion structure 12 can slide relative to the vehicle body through the moving rail 41 and the fixed rail 42.

[0052] like Figures 1-4 , Figure 9 and Figure 13As shown, the moving rail 41 and the fixed rail 42 are disposed between the seat cushion structure 12 and the vehicle body and are respectively connected to the seat cushion structure 12 and the vehicle body. The moving rail 41 can slide relative to the fixed rail 42, thereby allowing the seat cushion structure 12 to slide relative to the vehicle body. For example, when the control structure 6 controls the slide rail moving mechanism 4 to unlock, the seat cushion structure 12 and the backrest structure 11 can slide forward along the fixed rail 42 under the drive of the moving rail 41, thereby realizing the forward movement of the seat 1 inside the vehicle. Thus, the fore-and-aft position of the seat 1 can be flexibly adjusted, so that the seat 1 can accommodate passengers of different heights and leg lengths, and can leave enough space behind the seat 1 to facilitate the passage of passengers.

[0053] In some embodiments, the seat lifting mechanism 3 includes a lifting elastic element 31, an active link 32, and a driven link 33, wherein the active link 32 and the driven link 33 are rotatably connected between the seat cushion structure 12 and the motion rail 41, respectively; wherein, the lifting elastic element 31 is disposed at the connection between the active link 32 and the seat cushion structure 12, for pushing the active link 32 to rotate and thereby driving the seat cushion structure 12 to lift. In other words, the seat cushion structure 12 can be rotatably connected to the motion rail 41 through the active link 32 and the driven link 33, so that the seat cushion structure 12 can rotate relative to the motion rail 41 through the active link 32 and the driven link 33, and the lifting elastic member 31 can push the seat cushion structure 12 to achieve the upward lifting of the seat cushion structure 12. That is, the lifting elastic member 31 can generate elastic force to drive the active link 32 to rotate from back to front, so as to drive the seat cushion structure 12 and the backrest structure 11 to lift upward, thereby causing the seat 1 to generate an upward lifting motion, so as to facilitate the motion rail 41 to drive the seat 1 to slide forward, and the seat 1 first lifts upward and then slides forward.

[0054] like Figures 1-4 and Figure 9 As shown, the active link 32 rotatably connects the front end of the seat cushion structure 12 to the motion rail 41, and the driven link 33 rotatably connects the rear end of the seat cushion structure 12 to the motion rail 41. This allows the seat cushion structure 12 to rotate upward relative to the motion rail 41 via the active link 32 and the driven link 33, thereby lifting the seat cushion structure 12. The lifting elastic element 31 is located at the connection between the active link 32 and the seat cushion structure 12 to apply an elastic force to the active link 32, thereby pushing the active link 32 to rotate and drive the lifting of the seat cushion structure 12 and the rotation of the driven link 33.

[0055] Therefore, by raising the elastic element 31, the active link 32 and the driven link 33, the seat cushion structure 12 can be raised, which facilitates the forward sliding of the seat cushion structure 12.

[0056] The active link 32 and the driven link 33 can each be two, and are respectively located on both sides of the seat cushion structure 12. Furthermore, the lifting elastic element 31 can be constructed as a torsion spring or other type of elastic element, thereby utilizing the torsional elastic force of the torsion spring to achieve the lifting of the seat cushion structure 12.

[0057] In some embodiments, the driven link 33 is provided with a first slide rail lock 331, and the unlocking mechanism 7 includes a second unlocking motor 73 and a second unlocking cable 74. The second unlocking motor 73 pulls the first slide rail lock 331 to move via the second unlocking cable 74 to unlock the driven link 33, and causes the active link 32 to rotate under the driving action of the lifting elastic member 31. That is, the locking and unlocking of the first slide rail lock 331 can be controlled by the second unlocking motor 73, thereby controlling the lifting of the seat cushion structure 12.

[0058] like Figure 9 and Figure 10 As shown, the first slide rail lock 331 is disposed on the driven link 33 and connected to one end of the second unlocking cable 74. The other end of the second unlocking cable 74 is connected to the second unlocking motor 73, so that the second unlocking motor 73 can control the locking and unlocking of the first slide rail lock 331 through the second unlocking cable 74. When the second unlocking motor 73 controls the second unlocking cable 74 to pull, the second unlocking cable 74 can control the first slide rail lock 331 to unlock. At this time, the lifting elastic element 31 can drive the active link 32 to lift the seat cushion structure 12 upward, thereby realizing the upward lifting of the seat 1, which is conducive to the forward sliding of the seat 1.

[0059] Therefore, the locking and unlocking of the first slide rail lock 331 can be flexibly controlled by the second unlocking motor 73 and the second unlocking cable 74, thereby controlling the lifting of the seat 1 and facilitating the forward movement of the seat 1.

[0060] It should be noted that the control structure 6 can control the first unlocking motor 71 and the second unlocking motor 73 respectively. That is, the control structure 6 can control the order of the forward tilt of the backrest structure 11 and the lifting of the seat cushion structure 12, thereby facilitating the control of the seat 1 and the avoidance of rear space.

[0061] In some embodiments, the slide rail moving mechanism 4 further includes a sliding elastic element 43, which is connected between the moving rail 41 and the fixed rail 42. The moving rail 41 is provided with a second slide rail lock 411 that engages with the fixed rail 42. During the process of lifting the seat cushion structure 12, the active linkage 32 pushes the second slide rail lock 411 to unlock, allowing the moving rail 41 to slide forward under the driving force of the sliding elastic element 43. In other words, the seat cushion structure 12 can slide forward after being lifted upwards to avoid structural interference.

[0062] like Figures 11-13As shown, the second slide rail lock 411 includes a second rotating shaft 4111, a rotating piece 4112, a first shaft pin 4113, an unlocking shaft pin 4114, an unlocking sheet metal 4115, and a third rotating shaft 4116. The second slide rail lock 411 is disposed between the moving rail 41 and the fixed rail 42 to lock the two. During the lifting process of the seat structure 12, the first shaft pin 4113 drives the rotating piece 4112 to rotate around the second rotating shaft 4111, thereby driving the unlocking sheet metal 4115 and one end connected to it to move downward around the third rotating shaft 4116. The unlocking sheet metal 4115 presses against the unlocking shaft pin 4114 to unlock the second slide rail lock 411. At this time, the moving rail 41 can slide relative to the fixed rail 42.

[0063] Additionally, a sliding elastic element 43 can be provided between the fixed rail 42 and the moving rail 41. The sliding elastic element 43 can generate an elastic force to drive the moving rail 41 to slide on the fixed rail 42. Specifically, one end of the sliding elastic element 43 can be connected to the fixed rail 42, and the other end can be connected to the moving rail 41. At this time, the sliding elastic element 43 generates an elastic force that causes the moving rail 41 to slide relative to the fixed rail 42. After the second slide rail lock 411 is unlocked, the sliding elastic element 43 can drive the moving rail 41 to slide forward on the fixed rail 42.

[0064] Therefore, the seat structure 12 can be lifted upward and then slid forward by means of the second slide rail lock 411 and the sliding elastic element 43, thereby avoiding structural interference.

[0065] The second rotating shaft 4111, rotating plate 4112, first shaft pin 4113, unlocking shaft pin 4114, unlocking sheet metal 4115 and third rotating shaft 4116 can all be made of metal. The second slide rail lock 411 can be unlocked after the seat structure 12 is raised to the set position by adjusting the structure of the unlocking sheet metal 4115 and the position of the first shaft pin 4113 on the rotating plate 4112. The motion rail 41, fixed rail 42 and sliding elastic element 43 can all be made of metal. The sliding elastic element 43 can be constructed as a spring. Different elastic forces can be obtained by adjusting the material and number of turns of the sliding elastic element 43.

[0066] This utility model also proposes a vehicle.

[0067] The vehicle according to the present invention includes a seat assembly 100 of any of the above embodiments. The backrest tilting mechanism 2, the seat lifting mechanism 3, and the slide rail moving mechanism 4 can be unlocked by operating button 5, thereby driving the backrest structure 11 of the seat 1 to tilt forward and the backrest structure 11 and seat cushion structure 12 to slide forward, thus providing a larger clearance space behind the seat 1 for passengers to pass through. Compared with traditional manually controlled vehicle seats 1, the operation is more convenient; compared with purely electrically controlled seats 1, the structure is simpler and the cost is lower. Furthermore, the seat assembly 100 can be applied to two-row seat vehicles, three-row seat vehicles, or other vehicles.
