[0002] With the development of vehicle technology, users have higher and higher requirements for vehicle space. The layout of vehicle seats has gradually increased from the conventional two rows of five seats to three rows of six seats, three rows of seven seats, etc., to meet the needs of multiple people traveling together in a family. Therefore, this requires the middle (i.e., second row) seats to have the function of quick entry and exit. By controlling the movement of the seats and the angle of the seat backs, the passage for the rear row (i.e., third row) passengers to enter the car is avoided, meeting the requirements of passengers for quick entry and exit.

[0035] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0036] like Figures 1 to 8 As shown, the embodiment of the utility model provides a linkage assembly of a vehicle seat, the linkage assembly 10 is used to connect with the angle adjustment assembly of the vehicle seat and the slide rail assembly of the vehicle seat, the angle adjustment assembly includes a transmission shaft 202 provided with a recliner 201, an upper connecting plate 203 of the recliner and a lower connecting plate 204 of the recliner, and the slide rail assembly includes a slide rail unlocking mechanism 205 and a slide rail locking mechanism 206;

[0037] The linkage component 10 comprises:

[0038] A first adjustment handle 101, which is disposed at a first end of the transmission shaft 202, and is used to unlock the angle adjuster 201;

[0039] A linkage bracket 102, which is rotatably disposed at the second end of the transmission shaft 202, and is connected to the slide rail unlocking mechanism 205;

[0040] A linkage shifting block 103, the linkage shifting block 103 is connected to the linkage bracket 102;

[0041] When the recliner 201 is unlocked, the upper connecting plate 203 of the recliner is rotatably connected to the lower connecting plate 204 of the recliner via the transmission shaft 202, and the linkage shift block 103 can move along with the rotation of the upper connecting plate 203 of the recliner;

[0042] When the linkage shifting block 103 is in a moving state, the linkage shifting block 103 can drive the linkage bracket 102 to rotate around the transmission shaft 202 , so that the slide rail unlocking mechanism 205 is driven by the linkage bracket 102 to unlock the slide rail locking mechanism 206 .

[0043] In one example, the upper connecting plate 203 of the recliner can be used to fix the backrest 20 of the vehicle seat, and the lower connecting plate 204 of the recliner can be used to fix the cushion 30 of the vehicle seat. When the rear row (i.e., the third row) passengers need to get in and out quickly, the user can rotate the first adjustment handle 101 to unlock the recliner 201 set on the transmission shaft 202. When the recliner 201 is unlocked, the upper connecting plate 203 of the recliner is rotatably connected to the lower connecting plate 204 of the recliner through the transmission shaft 202. In other words, the angle of the backrest of the vehicle seat can be adjusted by the first adjustment handle 101.

[0044] The upper connecting plate 203 of the recliner can be in contact with the linkage shift block 103. The user pushes the upper connecting plate 203 of the recliner (that is, the user adjusts the backrest angle), so that the rotation of the upper connecting plate 203 of the recliner drives the movement of the linkage shift block 103. At the same time, the linkage shift block 103 can drive the linkage bracket 102 to rotate around the transmission shaft 202, so that the slide rail unlocking mechanism 205 is driven by the linkage bracket 102 to unlock the slide rail locking mechanism 206.

[0045] In the embodiment of the utility model, a linkage assembly is provided on the vehicle seat, and the first adjustment handle 101 is used to unlock the angle adjuster 201 to adjust the backrest angle; at the same time, during the backrest angle adjustment process, the rotation of the connecting plate 203 on the angle adjuster can drive the movement of the linkage shift block 103, and the linkage shift block 103 pushes the linkage bracket 102 to rotate around the transmission shaft 202, so that the slide rail unlocking mechanism 205 is driven by the linkage bracket 102 to unlock the slide rail locking mechanism 206, so that the vehicle seat can be moved on the slide rail. The first adjustment handle 101 can simultaneously adjust the inclination angle of the vehicle seat back and the position of the vehicle seat on the slide rail, quickly expand the entry and exit channel for rear passengers, simplify the operation steps, and improve the convenience of adjusting the vehicle seat.

[0046] Specifically, the first end of the linkage block 103 is rotatably connected to the linkage bracket 102. When the second end of the linkage block 103 is toward the upper connecting plate 203 of the recliner, the adjustable range of the angle between the upper connecting plate 203 of the recliner and the lower connecting plate 204 of the recliner is a first angle range. When the angle between the upper connecting plate 203 of the recliner and the lower connecting plate 204 of the recliner is a target angle, the second end of the linkage block 103 abuts against the upper connecting plate 203 of the recliner to move following the rotation of the upper connecting plate 203 of the recliner.

[0047] In some embodiments, the first end of the linkage block 103 can be rotatably connected to the linkage bracket 102, so that the second end of the linkage block 103 can be oriented toward the upper connecting plate 203 of the recliner, or the second end of the linkage block 103 can be away from the upper connecting plate 203 of the recliner. In the case where the second end of the linkage block 103 is oriented toward the upper connecting plate 203 of the recliner, that is, the second end of the linkage block 103 is disposed on the transmission path when the upper connecting plate 203 of the recliner rotates, such as Figure 3 As shown. After unlocking the recliner 201 by the first adjustment handle 101, the user can push the seat back to tilt toward the front row to expand the entry and exit channel for the rear passengers; during the process of the seat back tilting toward the front row, the angle A between the upper connecting plate 203 of the recliner and the lower connecting plate 204 of the recliner gradually decreases. Exemplarily, the range of angle A at this time can be 150° to 240°. When the angle A between the upper connecting plate 203 of the recliner and the lower connecting plate 204 of the recliner is reduced to the target angle (the target angle can be 152°), the second end of the linkage shift block 103 abuts against the upper connecting plate 203 of the recliner, as shown. Figure 7 shown.

[0048] Considering that when the seat back tilts too much toward the front row, it is difficult for the vehicle seat to move toward the front row through the slide rail, and thus it is difficult to achieve the purpose of expanding the rear passenger access channel. Based on this, in this embodiment, the second end of the linkage shift block 103 is arranged on the transmission path when the upper connecting plate 203 of the recliner rotates, so as to limit the adjustable range of the angle A between the upper connecting plate 203 of the recliner and the lower connecting plate 204 of the recliner, and reduce the situation where the seat back tilts too much toward the front row. At the same time, after the second end of the linkage block 103 abuts against the upper connecting plate 203 of the recliner, the seat back is continuously pushed, so that the upper connecting plate 203 of the recliner continues to rotate through the transmission shaft 202 (for example, the angle A is adjusted from 152° to 150°), and the upper connecting plate 203 of the recliner can drive the linkage bracket 102 to rotate around the transmission shaft 202 through the linkage block 103, so that the slide rail unlocking mechanism 205 unlocks the slide rail locking mechanism 206 under the drive of the linkage bracket 102, so that the vehicle seat can be moved on the slide rail. The first adjustment handle 101 can simultaneously adjust the inclination angle of the vehicle seat back and the position of the vehicle seat on the slide rail, quickly expand the entry and exit channel for rear passengers, simplify the operation steps, and improve the convenience of adjusting the vehicle seat.

[0049] Optionally, the upper connecting plate 203 of the recliner is provided with a limit plate 2031 , and when the angle between the upper connecting plate 203 of the recliner and the lower connecting plate 204 of the recliner is the target angle, the second end of the linkage shifting block 103 abuts against the limit plate 2031 .

[0050] In this example, by setting a limit plate 2031 on the upper connecting plate 203 of the recliner, and when the second end of the linkage block 103 is facing the upper connecting plate 203 of the recliner, the second end of the linkage block 103 is set on the transmission path when the limit plate 2031 rotates. In this way, the second end of the linkage block 103 abuts against the limit plate 2031, and the adjustable range of the angle A between the upper connecting plate 203 of the recliner and the lower connecting plate 204 of the recliner is limited, thereby reducing the situation where the angle of the seat back tilting toward the front row is too large. At the same time, after the second end of the linkage block 103 abuts against the limit plate 2031, the seat back is continuously pushed, so that the limit plate 2031 can drive the linkage bracket 102 to rotate around the transmission shaft 202 through the linkage block 103, so that the slide rail unlocking mechanism 205 is driven by the linkage bracket 102 to unlock the slide rail locking mechanism 206, so that the vehicle seat can be moved on the slide rail. The first adjustment handle 101 can be used to simultaneously adjust the inclination angle of the vehicle seat back and the position of the vehicle seat on the slide rail, quickly expanding the entry and exit channel for rear passengers, simplifying the operating steps, and improving the convenience of adjusting the vehicle seat.

[0051] Optionally, when the second end of the linkage shift block 103 is away from the upper connecting plate 203 of the recliner, the adjustable range of the angle between the upper connecting plate 203 of the recliner and the lower connecting plate 204 of the recliner is a second angle range, which is greater than the first angle range.

[0052] In other embodiments, considering that there are some usage scenarios where the rear passenger access channel does not need to be expanded, for example, in the usage scenario of expanding the luggage compartment space, the seat back needs to be completely laid flat. Therefore, the linkage block 103 can be movably connected to the linkage bracket 102. When the second end of the linkage block 103 is away from the upper connecting plate 203 of the recliner, that is, the second end of the linkage block 103 is not set on the transmission path when the upper connecting plate 203 of the recliner rotates, as shown in FIG. Figure 4 As shown. After unlocking the recliner 201 through the first adjustment handle 101, the user can push the seat back to tilt toward the front row until the seat back is laid flat, expanding the rear storage space; during the process of the seat back tilting toward the front row, the angle A between the upper connecting plate 203 of the recliner and the lower connecting plate 204 of the recliner gradually decreases. Exemplarily, since there is no obstruction of the linkage shift block 103 on the transmission path when the upper connecting plate 203 of the recliner rotates, the angle A can range from 90° to 240°. When the angle A between the upper connecting plate 203 of the recliner and the lower connecting plate 204 of the recliner is reduced to 90°, the seat back is flush with the seat cushion (not shown in the figure), that is, the seat back is in a flat state, as shown in FIG. Figure 6 shown.

[0053] Optionally, the linkage component 10 further includes:

[0054] The fixed bracket 104 , the linkage bracket 102 and the slide rail unlocking mechanism 205 are fixed to the lower connecting plate 204 of the angle adjuster through the fixed bracket 104 .

[0055] In this embodiment, the fixed bracket 104 is arranged at the second end of the transmission shaft 202, and the fixed bracket 104 is arranged on the lower connecting plate 204 of the recliner to fix the linkage bracket 102 and the slide rail unlocking mechanism 205, and the linkage bracket 102 is rotatably connected to the fixed bracket 104, so that the linkage bracket 102 is rotatably arranged at the second end of the transmission shaft 202. In this way, the limit plate 2031 can drive the linkage bracket 102 to rotate around the transmission shaft 202 through the linkage shifting block 103, so that the slide rail unlocking mechanism 205 unlocks the slide rail locking mechanism 206 under the drive of the linkage bracket 102, so that the linkage bracket 102 can unlock the slide rail locking mechanism 206, thereby enhancing the stability of the connection between the various structures of the linkage assembly 10.

[0056] Optionally, the linkage component 10 further includes:

[0057] A second adjustment handle 105, which is disposed at the second end of the transmission shaft 202, and a first elastic member 106 is disposed on the second adjustment handle 105, and the second adjustment handle 105 is connected to the second end of the linkage shift block 103 through the first elastic member 106;

[0058] In the initial state, the second adjustment handle 105 supports the second end of the linkage shift block 103 through the first elastic member 106 toward the upper connecting plate 203 of the angle adjuster;

[0059] When the second adjusting handle 105 is rotated to a preset angle, the second adjusting handle 105 pulls the second end of the linkage shift block 106 away from the upper connecting plate 203 of the angle adjuster through the first elastic member 106 .

[0060] In one example, in the initial state of the second adjustment handle 105, the second adjustment handle 105 supports the second end of the linkage shift block 103 toward the upper connecting plate 203 of the recliner through the first elastic member 106, so that the second end of the linkage shift block 103 is arranged on the transmission path when the upper connecting plate 203 of the recliner rotates under the support of the first elastic member 106, such as Figure 3 After unlocking the recliner 201 through the first adjustment handle 101, the user can push the seat back to tilt toward the front row to expand the ingress and egress passage for rear passengers; during the process of the seat back tilting toward the front row, when the angle between the recliner upper connecting plate 203 and the recliner lower connecting plate 204 decreases to the target angle, the second end of the linkage shift block 103 abuts against the recliner upper connecting plate 203, as shown in FIG. Figure 5 and Figure 7As shown. Continue to push the seat back, so that the upper connecting plate 203 of the recliner continues to rotate through the transmission shaft 202, and the upper connecting plate 203 of the recliner can drive the linkage bracket 102 to rotate around the transmission shaft 202 through the linkage block 103, so that the slide rail unlocking mechanism 205 is driven by the linkage bracket 102 to unlock the slide rail locking mechanism 206, so that the vehicle seat can be moved on the slide rail. The first adjustment handle 101 can simultaneously adjust the inclination angle of the vehicle seat back and the position of the vehicle seat on the slide rail, quickly expand the entry and exit channel for rear passengers, simplify the operation steps, and improve the convenience of adjusting the vehicle seat.

[0061] In another example, considering the need to lay the seat back completely flat, a second adjustment handle 105 can be provided. By rotating the second adjustment handle 105 at a preset angle, the second end of the linkage shift block 103 is pulled away from the transmission path when the connecting plate 203 on the angle adjuster rotates under the traction of the first elastic member 106, such as Figure 4 As shown, the second adjustment handle 105 pulls the second end of the linkage block 106 away from the upper connecting plate 203 of the recliner through the first elastic member 106. After unlocking the recliner 201 through the first adjustment handle 101, the user can push the seat back to tilt toward the front row until the seat back is flat, thereby expanding the rear storage space; during the process of the seat back tilting toward the front row, since there is no blocking of the linkage block 103 on the transmission path when the upper connecting plate 203 of the recliner rotates, the angle between the upper connecting plate 203 of the recliner and the lower connecting plate 204 of the recliner can be reduced to 90°, as shown in FIG. Figure 6 As shown, the seat back is in a flat position, that is, the seat back is flush with the seat cushion (not shown in the figure).

[0062] Among them, the second adjustment handle 105 is also connected to a second elastic member 107, one end of the second elastic member 107 is connected to the second adjustment handle 105, and the other end of the second elastic member 107 is connected to the fixed bracket 104. When the second adjustment handle 105 is rotated to a preset angle, the second elastic member 107 has elastic potential energy, which can drive the second adjustment handle 105 to rotate to maintain the initial state.

[0063] Among them, a third elastic member 108 is also connected to the linkage bracket 102, one end of the third elastic member 108 is connected to the linkage bracket 102, and the other end of the third elastic member 108 is connected to the fixed bracket 104. When the linkage block 103 drives the linkage bracket 102 to rotate around the transmission shaft 202, the third elastic member 108 has elastic potential energy, which can drive the linkage bracket 102 to rotate to lock the slide rail unlocking mechanism 205.

[0064] Among them, a fourth elastic member 109 is also connected to the first adjustment handle 101, one end of the fourth elastic member 109 is connected to the first adjustment handle 101, and the other end of the fourth elastic member 109 is connected to the lower connecting plate 204 of the angle adjuster on the side of the first end of the transmission shaft 202. When the first adjustment handle 101 is rotated to unlock the angle adjuster 201, the fourth elastic member 109 has elastic potential energy, which can drive the first adjustment handle 101 to rotate to lock the angle adjuster 201.

[0065] The first elastic member 106 , the second elastic member 107 , the third elastic member 108 and the fourth elastic member 109 may all be springs.

[0066] Alternatively, if Figure 8 As shown, at the connection position between the second adjustment handle 105 and the transmission shaft 202, the size of the shaft key 2021 of the transmission shaft 202 is smaller than the size of the key slot 1051 of the second adjustment handle 105, so as to form an idle travel rotation angle α between the second adjustment handle 105 and the transmission shaft 202, and the angle of the idle travel rotation angle α is greater than the angle of rotation of the transmission shaft 202 when the adjuster 201 is unlocked.

[0067] In this embodiment, when rapid in-and-out adjustment is required, the first adjustment handle 101 is rotated to drive the transmission shaft 202 to rotate counterclockwise to unlock the recliner 201. At this time, the second adjustment handle 105 and the transmission shaft 202 have an idle travel rotation angle of angle α (α is greater than the angle of rotation of the transmission shaft 202 when the recliner 201 is unlocked); at the same time, there is the effect of the second elastic member 107. Therefore, in the process of unlocking the recliner 201, the second adjustment handle 105 has no rotation stroke to reduce the situation where the vehicle seat is difficult to move toward the front row due to excessive tilting of the seat back. After unlocking the recliner 201, the upper connecting plate 203 of the recliner hits the linkage block 103 and drives the linkage bracket 102 to rotate clockwise, thereby pulling the slide rail unlocking mechanism 205 assembled on the fixed bracket 104, thereby synchronously unlocking the slide rail. The rapid in-and-out function is realized. When rapidly in and out, the backrest will not be laid flat, and the forward avoidance space of the seat will not be affected.

[0068] Optionally, on the side of the limit plate 2031 facing the linkage block 103, the limit plate 2031 is provided with a guide groove adapted to the linkage block, thereby enhancing the stability of the limit plate 2031 when in contact with the linkage block 103 and reducing the slippage between the linkage block 103 and the limit plate 2031.

[0069] In this embodiment, by setting a linkage component 10 on the vehicle seat, the two functional states of backrest angle adjustment and quick entry and exit can be effectively distinguished; it is beneficial to share five / seven-seat two-row seats, and the development cost is low; through the idle stroke coordination design of the second adjustment handle 105, when operating the quick entry and exit handle, the backrest adjustment handle will not produce synchronous displacement, which can reduce the occurrence of failures and improve reliability.

[0070] The embodiment of the utility model further provides a vehicle seat, comprising a seat body and the above-mentioned linkage assembly.

[0071] It should be noted that the implementation method of the embodiment of the linkage assembly of the above-mentioned vehicle seat is also applicable to the embodiment of the vehicle seat and can achieve the same technical effect, which will not be repeated here.
