The traditional seat adjuster adopts a transverse clamping structure, which moves the seat through mechanical parts such as slide rails, gears and clamps, and locks it in the desired position through a clamping device.

[0003] However, the disadvantages of the transverse snap-in structure mainly include complex structure, numerous parts, complex interactions and large space occupation. This not only increases the difficulty and cost of manufacturing, but also leads to more potential failure points, increasing repair and maintenance costs. Especially in compact cars, due to space constraints, this structure may affect the flexibility of seat layout. Utility Model Content

[0004] The utility model aims to provide a seat adjuster to solve the technical problem of high manufacturing cost of the seat adjuster caused by the complex structure, numerous parts, complex interactions and other characteristics of the transverse clamping structure in the prior art.

[0005] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0007] When in the locked state, the pin can extend into the slot and engage with the slot. When the pin is engaged with the slot, the sliding plate cannot slide along the guide groove. A pulling component is also installed on the sliding plate. When in the adjustment state, the pulling component can pull the pin out of the slot, and the sliding plate can slide relative to the sliding guide groove to achieve relative position adjustment of the seat and the backrest.

[0008] The working principle of the utility model is as follows: the utility model adopts a structure that is longitudinally connected with the sliding guide groove, and realizes locking and fixing by connecting the side pin with the slot, and realizes separation of the pin and the slot by pulling the pulling force of the pulling component on the pin, so that the sliding plate slides to realize seat adjustment, which simplifies the number of parts, reduces assembly time and total parts cost, and reduces the weight of seat accessories.

[0009] As one implementation of the sliding plate being slidably connected with a latch, one side of the sliding plate has an extension plate extending perpendicularly to the sliding direction, and the extension plate is provided with a first channel;

[0010] A perforated plate arranged parallel to the extension plate is fixed at the bottom of the sliding plate, a gap is formed between the perforated plate and the extension plate, and a second hole corresponding to the position of the first hole is formed on the perforated plate;

[0016] One end of the pull wire passing through the sheath is clamped with the pull plate. When the pull wire is pulled, it can drive the pull plate to move, thereby driving the latch to retreat from the first channel and the second channel and withdraw from the slot. At this time, the sliding plate can slide along the sliding guide groove.

[0017] Using a pull wire as the core component of the pulling assembly can further reduce the number of parts, simplify the part structure, and reduce assembly time and total part cost.

[0043] In order to better understand the purpose, structure and function of the present invention, a seat adjuster of the present invention is further described in detail below in conjunction with the accompanying drawings.

[0044] The utility model can be applied to automobile seats, and solves the technical problem of high manufacturing cost of seat adjusters caused by the complex structure, numerous parts, complex interactions and other characteristics of the transverse clamping structure in the prior art.

[0045] See also Figure 1 and Figure 2Based on the technical problems solved above, the utility model discloses a seat adjuster for installation on a car seat, comprising a sliding guide groove 401 for connecting with a backrest of a seat, a sliding plate 404 is slidably connected in the sliding guide groove 401, and the sliding plate 404 can slide in the sliding guide groove 401 along the extension direction of the sliding guide groove 401; a lock 500 is installed on the sliding plate 404 for connecting with the seat of the seat; a latch 200 is slidably connected to the sliding plate 404, and a plurality of card slots 402 are provided on the side wall of the sliding guide groove 401 on one side along the sliding direction;

[0046] When in the locked state, the latch 200 can extend into the slot 402 and engage with the slot 402. When the latch 200 is engaged with the slot 402, the sliding plate 404 cannot slide along the guide groove. A pulling assembly 300 is also installed on the sliding plate 404. When in the adjustment state, the pulling assembly 300 can pull the latch 200 out of the slot 402, and the sliding plate 404 can slide relative to the sliding guide groove 401 to achieve relative position adjustment of the seat and the backrest.

[0047] The working principle of the utility model is as follows: the utility model adopts a structure that is longitudinally connected with the sliding guide groove 401, and realizes locking and fixing by connecting the side pin 200 with the slot 402. The pulling force of the pulling component 300 on the pin 200 is used to separate the pin 200 from the slot 402, and then the sliding plate 404 is slid to realize seat adjustment, which simplifies the number of parts, reduces assembly time and total parts cost, and reduces the weight of seat accessories.

[0048] As one implementation of the sliding plate 404 with the latch 200 slidably connected, please refer to Figures 1 to 3 The sliding plate 404 has an extension plate 403 extending perpendicularly to the sliding direction on one side, and a first hole 405 is formed on the extension plate 403; a perforated plate 101 arranged parallel to the extension plate 403 is fixed to the bottom of the sliding plate 404, a gap is formed between the perforated plate 101 and the extension plate 403, and a second hole 107 corresponding to the position of the first hole 405 is formed on the perforated plate 101; a dial plate 102 is provided on one side of the perforated plate 101, and a second hole 107 corresponding to the position of the second hole 107 is formed on the dial plate 102 Corresponding to the third hole 103; a flange 201 is fixed to one end of the latch 200, and the other end of the latch 200 can pass through the third hole 103, the second hole 107 and the first hole 405 in sequence, and a snap-on portion 202 extends from the first hole 405, and the snap-on portion 202 is used to snap into the slot 402; the pull plate 102 can be pulled by the pulling assembly 300, so that the latch 200 can slide in the first hole 405, the second hole 107 and the third hole 103 driven by the pull plate 102.

[0049] The provision of the hole enables the latch 200 to slide more smoothly in the hole when being pulled, thereby improving the smoothness during the seat adjustment process.

[0050] As one embodiment of the pulling assembly 300, please refer to Figure 3 and Figure 5 The pulling assembly 300 includes a pull wire 301, the pull wire 301 is provided with a sheath 303, one end of the sheath 303 is fixed with a fixed end 304, the pull wire 301 passes through the sheath 303, and can extend from or retract into the sheath 303 under the action of an external force;

[0051] One end of the pull wire 301 passing through the sheath 303 is engaged with the shift plate 102. When the pull wire 301 is pulled, it can drive the shift plate 102 to move, thereby driving the latch 200 to retreat from the first channel 405 and the second channel 107, and withdraw from the slot 402. At this time, the sliding plate 404 can slide along the sliding guide groove 401.

[0052] Using the pull wire 301 as the core component of the pulling assembly 300 can further reduce the number of parts, simplify the part structure, and reduce the assembly time and total part cost.

[0053] For one specific implementation of the embodiment in which the end of the pull wire 301 passing through the sheath 303 is engaged with the dial plate 102, please refer to Figure 5 and Figure 6 A clamping end 305 is fixed on one end of the pull wire 301 passing through the sheath 303. The clamping end 305 includes a first chuck 306 and a second chuck 307. The first chuck 306 and the second chuck 307 are respectively fixedly connected to the pull wire 301, and there is a gap between the first chuck 306 and the second chuck 307;

[0054] The pull plate 102 is provided with a first notch 104, and the pull wire 301 between the first chuck 306 and the second chuck 307 is located in the first notch 104. The first chuck 306 and the second chuck 307 can cover the notch area. The end of the pull wire 301 passing through the second chuck 307 is fixed with a blocking member 302. The blocking member 302 can prevent the pull wire 301 from falling off from the second chuck 307 when the pull wire 301 is pulled.

[0055] Using a chuck to clamp the pull wire 301 and the dial plate 102 can further simplify the parts structure. At the same time, the clamping end 305 only needs to be installed into the gap from the opening of the first gap 104 to achieve the clamping connection, which can reduce the difficulty of installation and improve the installation efficiency.

[0056] As a preference, see Figure 5 and Figure 6 , a reinforcing plate assembly is fixed on the sliding plate 404, and the perforated plate 101 is fixed on the reinforcing plate assembly;

[0057] A support frame 105 is also fixed on the reinforcing plate assembly. A second notch 106 is opened on the support frame 105. The fixed end 304 is clamped with the second notch 106. The pull wire 301 at the center of the fixed end 304 and the center of the clamping end 305 is in a horizontal position.

[0058] The reinforcement plate assembly is provided to integrate and modularize the functions of the pulling assembly 300 and the latch 200. In actual installation, the reinforcement plate assembly is installed on the sliding plate 404, and there is no need to separately install the perforated plate 101, the support frame 105 and other parts, thereby improving the efficiency of production and installation. The function of the fixed end 304 is to keep the pull wire 301 between the first notch 104 and the second notch 106 in a horizontal state. When the pull wire 301 is pulled, the pull wire 301 can move horizontally, thereby causing the dial plate 102 to move horizontally, thereby causing the latch 200 to move horizontally, so as to increase the stable movement of the entire seat adjuster.

[0059] As a preference, see Figure 2 and Figure 3 A return spring 203 is sleeved on the latch 200 between the perforated plate 101 and the extension plate 403, and one end of the return spring 203 is fixed to the perforated plate 101. In this way, when the plate 102 drives the latch 200 to withdraw from the slot 402, the return spring 203 undergoes elastic compression deformation to store elastic potential energy. When the pull wire 301 no longer applies force to the plate 102, the elastic potential energy of the return spring 203 is released, driving the plate 102 and the latch 200 to reset, and the latch 200 is again engaged with the slot 402 to achieve seat adjustment.

[0060] As a preferred option for seat adjusters, see Figure 4 , a plurality of first holes 405 are formed on the extension plate 403, and the same number of second holes 107 are formed on the corresponding perforated plate 101, and the same number of third holes 103 are formed on the dial plate 102, and each corresponding first hole 405, second hole 107 and third hole 103 serve as a group of adjustment holes, and each group of adjustment holes is provided with a latch 200, and each latch 200 between the perforated plate 101 and the extension plate 403 is respectively installed with a return spring 203, and one end of each return spring 203 is fixed to the perforated plate 101;

[0061] In the locked state, at least two of the latches 200 can extend into the locking groove 402 and engage with the locking groove 402 to prevent the sliding plate 404 from sliding along the guide groove;

[0062] In the adjustment state, the pull wire 301 pulls the dial plate 102 to move, and each latch 200 can be driven by the dial plate 102, and at the same time slides in the corresponding adjustment channel and withdraws from the slot 402. At this time, the sliding plate 404 can slide along the sliding guide groove 401 to adjust the seat.

[0063] By providing a plurality of adjustment holes and a plurality of latches 200, the force on the seat adjuster can be more evenly distributed when the seat adjuster is in a locked state, and the state of the seat can be more stable. When the car shakes during driving, the latch 200 is not easy to fall out of the slot 402, and the overall structure is not easy to deform, thereby improving the structural stability and increasing the service life.

[0064] As one example of a seat adjuster, see Figure 5 and Figure 6 The extension plate 403 is provided with three first holes 405, the corresponding perforated plate 101 is provided with the same number of second holes 107, the dial plate 102 is provided with the same number of third holes 103, and there are three groups of adjustment holes, each group of adjustment holes is provided with a first latch 901, a second latch 902 and a third latch 903;

[0065] A first return spring 904, a second return spring 905 and a third return spring 906 are respectively installed on each latch 200 between the perforated plate 101 and the extension plate 403, and one end of the first return spring 904, the second return spring 905 and the third return spring 906 are respectively fixed to the perforated plate 101;

[0066] In the locked state, two latches 200 among the first latch 901, the second latch 902 and the third latch 903 can always extend into the slot 402 and engage with the slot 402 to prevent the sliding plate 404 from sliding along the guide slot, and the other latch 200 will be blocked by the sliding guide slot 401 structure between two adjacent slots 402;

[0067] In the adjustment state, the pull wire 301 pulls the dial plate 102 to move, and each latch 200 can be driven by the dial plate 102, and at the same time slides in the corresponding adjustment channel and withdraws from the slot 402. At this time, the sliding plate 404 can slide along the sliding guide groove 401 to adjust the seat.

[0068] Three groups of adjustment channels and three latches 200 are provided, and there are always two latches 200 that can extend into the slot 402 and engage with the slot 402 to prevent the sliding plate 404 from sliding along the guide groove, and the other latch 200 will be blocked by the sliding guide groove 401 structure between two adjacent slots 402. Then, the other latch 200 that is not engaged with the slot 402 will apply pressure to the side wall of the sliding guide groove 401 under the action of the return spring 203, which can further increase the stability of the seat adjuster when it is in the locked state.

[0069] Specifically, the sliding guide groove 401 is fixed to the vehicle body through a first fixing plate 701 and a second fixing plate 702 , and the first fixing plate 701 and the second fixing plate 702 are fixedly connected to two ends of the sliding guide groove 401 , respectively.

[0070] Specifically, the card slot 402 is square.

[0071] Specifically, a connecting bracket 600 is also fixed on the second fixing plate 702 for connecting with the backrest of the seat.

[0072] The working process of the utility model is: when the seat needs to be adjusted, the fixed end 304 of the pulling component 300 is clamped on the second notch 106 of the support frame 105 of the reinforcement plate assembly, and the clamping end 305 is clamped with the dial plate 102. By pulling the pull wire 301, the dial plate 102 is driven to move in the direction away from the extension plate 403. At the same time, the flange 201 at one end of the latch 200 extending from the adjustment channel is placed on the dial plate 102, and moves together with the dial plate 102 in the direction away from the extension plate 403, so that the latch 200 is disengaged from the slot 402, and the sliding plate 404 can move freely until it is clamped with the next slot 402 gear again.

[0073] The seat adjuster disclosed by the utility model has the following technical effects:

[0074] 1. The utility model adopts a seat adjuster that is different from the snap-on seat adjuster in the prior art. It adopts a structure that is snap-on with the sliding guide groove in the longitudinal direction. The locking and fixing are achieved by snapping the side latch with the slot. The seat adjustment is achieved by sliding the sliding plate. This simplifies the number of parts, reduces the assembly time and the total parts cost, and reduces the weight of the seat accessories.

[0075] 2. In the present invention, the latch and the sliding guide slot are used to lock the seat back, and the latch is pulled out of or out of the slot by the pull wire to achieve angle adjustment. This design is efficient and stable, and has obvious advantages in both manufacturing and use. Compared with the horizontal latch structure, the seat adjuster disclosed in the present invention is simpler, more economical and more effective.

[0076] 3. Overall, the transverse snap-in structure has some functional advantages in car seat adjusters, but its complex structure and high cost limit its application. In the future, more advanced, lightweight, and cost-effective designs and structures may replace the traditional transverse snap-in system to improve performance and reduce manufacturing costs.
