[0056] In addition, the positions of the second pull wire 9 and the locking member 13 are different, and an included angle is defined between the first plate 121 and the second plate 122, for example, the first plate 121 can be located in the direction of the inner side of the second plate 122 along the seat 100, which facilitates the connection of the first plate 121 to the second pull wire 9, and also facilitates the connection of the second plate 122 to the locking member 13.

[0057] In some embodiments, the bottom of the cushion framework 2 includes a seat rail 21, the locking member 13 is movably connected to the seat rail 21, the seat rail 21 is selectively slidable relative to the floor rail 101, the floor rail 101 is provided with a locking groove 1013, the locking member 13 is provided with a locking tooth 1311, and when the seat backrest 1 is folded by rotating relative to the cushion framework 2, the linkage plate assembly 12 is adapted to drive the locking member 13 to move so that the locking tooth 1311 is separated from the locking groove 1013 and the seat rail 21 is unlocked from the floor rail 101.

[0058] That is, the locking member 13 is movable relative to the seat rail 21 and the cushion framework 2, when the locking member 13 is moved downward relative to the seat rail 21 under the driving of the linkage plate, the locking tooth 1311 of the locking member 13 is separated from the locking groove 1013 of the floor rail 101, so that the seat rail 21 is unlocked from the floor rail 101; for example, a resilient member can be arranged between the locking member 13 and the seat rail 21, when the locking member 13 is in a natural state, that is, not pressed by the linkage plate assembly 12, the resilient member provides a force to the locking member 13 and the locking groove 1013 to keep the locking tooth 1311 and the locking groove 1013 locked; and it should be noted that when the linkage plate assembly 12 drives the locking member 13 to press downward, the pressing force is greater than the force of the resilient member, so that the locking member 13 and the locking groove 1013 are quickly unlocked.

[0059] In some embodiments, the locking groove 1013 includes an opening that is open downward, and the bottom of the locking member 13 is provided with a locking tooth 1311, and when the locking member 13 passes through the seat rail 21 and is adapted to move downward under the driving of the linkage plate assembly 12, the locking tooth 1311 is unlocked from the locking groove 1013.

[0060] Referring to Figure 7 ,Figure 8 and Figure 9 As shown, a portion of the seat slide rail 21 is located within the floor slide rail 101. The outer side 1011 of the floor slide rail 101 is bent inward to form the inner side 1012. (Refer to...) Figure 8 As shown, the inner side 1012 is provided with multiple downward-facing locking grooves 1013. The seat slide rail 21 also has corresponding movable grooves at positions opposite to the locking grooves 1013, allowing the locking member 13 to move up and down along the seat slide rail 21. The locking member 13 includes a connecting part 132 and a locking part 131. The locking part 131 includes multiple locking teeth 1311. The extending direction of the locking teeth 1311 is perpendicular to the opening direction of the locking groove 1013. When the locking member 13 is pressed down to disengage the locking teeth 1311 from the locking groove 1013 of the floor slide rail 101, the seat slide rail 21 can slide relative to the floor slide rail 101. By setting the opening of the locking groove 1013 downward and moving the locking member 13 downward to unlock, it is easy for the locking teeth 1311 to separate from the locking groove 1013, and it is easy to lock during reset.

[0061] In some embodiments, the seat 100 further includes a slide rail linkage shaft 8, which is rotatably connected to the seat cushion frame 2. Both sides of the seat 100 are provided with locking structures, which are fixedly connected to the slide rail linkage shaft 8. When the second pull cable 9 pulls the locking structure on one side to unlock, the locking structure on the other side is simultaneously unlocked by driving the slide rail linkage shaft 8.

[0062] In practice, the drive wheel 7 pulls the second cable 9 to move, and the linkage plate assembly 12 is fixedly connected to the slide rail linkage shaft 8. The slide rail linkage shaft 8 rotates relative to the seat frame 2. When the second cable 9 moves, it can drive the linkage plate assembly 12 on one side to rotate and cause the locking member 13 on that side to move downward. Correspondingly, the linkage plate assembly 12 drives the slide rail linkage shaft 8 to rotate clockwise. During the clockwise rotation of the slide rail linkage shaft 8, it drives the linkage plate assembly 12 on the other side to move, causing the linkage plate assembly 12 on the other side to drive the locking member 13 on the other side to move downward. That is, by connecting the linkage plate assembly 12 on one side through the second cable 9, combined with the setting of the slide rail linkage shaft 8, the locking members 13 on both sides can move downward, which correspondingly unlocks the seat slide rail 21 and the floor slide rail 101 on both sides. The entire structure is unlocked through a single action, saving time and effort. Of course, the slide rail linkage shaft 8 is also fixedly connected to the towel rack 102. When the towel rack 102 is rotated and the linkage plate assembly 12 is rotated clockwise, the seat slide rail 21 and the floor slide rail 101 can also be unlocked, achieving the same unlocking effect as the second transmission mechanism mentioned above.
