[0029] The following refers to Figure 1 - Figure 2 to describe a vehicle seat 100 according to an embodiment of the present utility model. The vehicle seat 100 can form a dual-zone adjustment mechanism 2 for the front and rear, which facilitates the user to adjust the seat in the front or rear, greatly improving the operation convenience, enabling the passenger to easily adjust the angle of the seat back 1, and the adjustment mechanism 2 can be installed inside the seat back 1, without occupying external space, improving the space utilization rate, and can adapt to seats of different sizes, being flexible and convenient.

[0030] As Figure 1 - Figure 2 shown, a vehicle seat 100 according to an embodiment of the present utility model includes: a seat back 1 and an adjustment mechanism 2.

[0031] The adjustment mechanism 2 is used to adjust the angle between the seat back 1 and the seat cushion to meet the most comfortable sitting postures of passengers and drivers, thereby improving the comfort and safety of riding. The adjustment mechanism 2 is installed on the seat back 1. In practice, the adjustment mechanism 2 can be installed inside the seat back 1, without occupying external space, improving the space utilization rate, and can adapt to seats of different sizes, being flexible and convenient.

[0032] The adjustment mechanism 2 includes a first zip component 21, a second zip component 22, and an angle adjuster 23. The first zip component 21, the second zip component 22, and the angle adjuster 23 are used to achieve the adjustment of the angle of the seat back 1. The angle adjuster 23 is connected to the seat back 1 and is used to adjust the angle of the seat back 1. The angle adjuster 23 has a locked state and an unlocked state. When in the unlocked state, the angle of the seat back 1 can be adjusted. After the adjustment is completed, it is in the locked state. Thus, the locking of different adjustment gears of the seat back 1 is realized, that is, after the seat adjusts the angle, the seat can be stably fixed at a certain angle, ensuring the reliability and stability of the passenger adjusting the seat angle and ensuring the safety of the passenger.

[0033] Among them, the first zipper assembly 21 and the second zipper assembly 22 are used to drive the recliner 23 to act respectively. At least part of the first zipper assembly 21 extends from the front side of the seat backrest 1, and at least part of the second zipper assembly 22 extends from the rear side of the seat backrest 1.

[0034] That is to say, the passenger can drive the recliner 23 to act by pulling the first zipper assembly 21 in front of the seat or the second zipper assembly 22 behind the seat, unlock the recliner 23, and realize the convenient adjustment of the angle of the seat backrest 1. Thus, a dual-zone adjustment mechanism 2 in the front and the rear can be formed, which is convenient for the user to adjust the seat in the front or the rear, greatly improving the operation convenience, enabling the passenger to easily adjust the angle of the seat backrest 1 to find a comfortable angle, and ensuring the reliability and stability of the adjustment process. In addition, the first zipper assembly 21 and the second zipper assembly 22 can be flexibly arranged at any position on the front side or the rear side of the seat backrest, which is convenient for the passenger to use.

[0035] According to the vehicle seat 100 of the embodiment of the present invention, by arranging the adjustment mechanism 2 on the seat backrest 1 to form a dual-zone adjustment mechanism 2 in the front and the rear, the passenger can drive the recliner 23 to act by pulling the first zipper assembly 21 in front of the seat or the second zipper assembly 22 behind the seat, unlock the recliner 23, and realize the convenient adjustment of the angle of the seat backrest 1, greatly improving the operation convenience. The passenger can easily adjust the angle of the seat backrest 1 to find a comfortable angle, and ensure the reliability and stability of the adjustment process. In addition, the adjustment mechanism 2 can be installed in the seat backrest 1 without occupying external space, improving the space utilization rate, and can adapt to seats of different sizes, which is flexible and convenient.

[0036] In some embodiments, the seat backrest 1 includes a backrest frame 11. The backrest frame 11 is the support frame of the seat, providing a stable structural support for the entire seat backrest 1 and ensuring that the seat backrest 1 can bear the weight of the passenger.

[0037] The adjustment mechanism 2 includes a labor-saving mechanism pull rod 24 and a transmission assembly 25. The labor-saving mechanism pull rod 24 is rotatably installed on the backrest frame 11. The labor-saving mechanism pull rod 24 is connected to the recliner 23 through the transmission assembly 25. The first zipper assembly 21 and the second zipper assembly 22 are respectively connected to the labor-saving mechanism pull rod 24 to drive the recliner 23 to act through the transmission assembly 25.

[0038] That is to say, the passenger can drive the labor-saving mechanism pull rod 24 to rotate relative to the backrest frame 11 by pulling the first zip component 21 or the second zip component 22. The rotation of the labor-saving mechanism pull rod 24 drives the transmission component 25 to move, and the movement of the transmission component 25 drives the seat angle adjuster 23 to move to realize the angle adjustment of the seat back 1. Thus, the power transmission from the first zip component 21 and the second zip component 22 to the angle adjuster 23 is realized. By setting the labor-saving mechanism pull rod 24, it is more labor-saving to adjust the seat back 1, and unlocking can be achieved without applying too much force, improving the convenience and comfort of operation. By setting the transmission component 25, the rotation of the labor-saving mechanism pull rod 24 can be smoothly and reliably converted into the action of the angle adjuster 23, thus ensuring the stability and accuracy of the angle adjustment of the seat back 1, and further improving the convenience, versatility and comfort of the seat adjustment, which can be applied to different vehicle seats 100.

[0039] It should be noted that the first zip component 21 and the second zip component 22 can be integrally integrated with the labor-saving mechanism pull rod 24. Using the principle of the lever arm, the labor-saving mechanism pull rod 24 can be driven to move with a small force to realize unlocking, greatly improving the user experience of the passenger. Moreover, the length of the labor-saving mechanism pull rod 24 can be flexibly adjusted according to the operating force requirements to adapt to different operating convenience requirements.

[0040] In some embodiments, the first zip component 21 includes a first adjusting strap 211 and a first unlocking cable 212. As Figure 2 shown, the first unlocking cable 212 is located inside the seat back 1 and is connected to the labor-saving mechanism pull rod 24, that is, the movement of the first unlocking cable 212 can drive the labor-saving mechanism pull rod 24 to rotate. One end of the first adjusting strap 211 is connected to the first unlocking cable 212 and the other end is located outside the front side of the seat back 1, that is, the first adjusting strap 211 partially extends outside and protrudes forward, which is conducive to the passenger pulling the first adjusting strap 211 from the front outside. The first adjusting strap 211 can drive the first unlocking cable 212 to move. Thus, when the first unlocking cable 212 is pulled, unlocking is triggered, and the labor-saving mechanism pull rod 24 can be driven to rotate. At this time, the angle of the seat back 1 can be adjusted to realize the comfortable adjustment with less effort in the front.

[0041] And / or, the second zip component 22 includes a second adjusting strap 221 and a second unlocking cable 222. As Figure 2As shown in the figure, the second unlocking cable 222 is located inside the seat backrest 1 and is connected to the labor-saving mechanism pull rod 24. That is, the movement of the second unlocking cable 222 can drive the rotation of the labor-saving mechanism pull rod 24. One end of the second adjustment strap 221 is connected to the second unlocking cable 222 and the other end is located outside the rear side of the seat backrest 1. That is, the second adjustment strap 221 extends partially outside and protrudes backward, which is conducive to the passenger pulling the second adjustment strap 221 from the rear outside. The second adjustment strap 221 can drive the movement of the second unlocking cable 222. Thus, when the second unlocking cable 222 is pulled, unlocking is triggered, and the rotation of the labor-saving mechanism pull rod 24 can be driven. At this time, the angle of the seat backrest 1 can be adjusted to achieve convenient adjustment with less effort from the rear.

[0042] In the actual design, the first adjustment strap 211 and the first unlocking cable 212 can be integrally designed, and the second adjustment strap 221 and the second unlocking cable 222 can be integrally designed. That is, the first adjustment strap 211 and the first unlocking cable 212 can be set as a whole, and the second adjustment strap 221 and the second unlocking cable 222 can be set as a whole. In this way, the user can complete the unlocking of the seat backrest 1 by pulling the first adjustment strap 211 or the action of the first adjustment strap 211, and can adjust it, which improves the operation convenience and makes the connection between the adjustment strap and the unlocking cable more reliable.

[0043] In some embodiments, an outer wing frame 12 is provided on the lateral outer side of the backrest frame 11. The outer wing frame 12 can enhance the supporting force of the seat backrest 1. The outer wing frame 12 is provided with a first strap outlet retaining bracket 13 and / or a second strap outlet retaining bracket 132. The first strap outlet retaining bracket 13 and the second strap outlet retaining bracket 132 are used to fix the outlet positions of the first adjustment strap 211 and the second adjustment strap 221, and respectively guide the movement paths of the first adjustment strap 211 and the second adjustment strap 221 to ensure that the straps extend or retract smoothly without obstruction and can be kept in the correct position when not in use.

[0044] The first strap outlet retaining bracket 13 is formed with a first guide outlet 131, and the first adjustment strap 211 is led out along the first guide outlet 131 toward the front side of the seat backrest 1. The second strap outlet retaining bracket 132 is formed with a second guide outlet 133, and the second adjustment strap 221 is led out along the second guide outlet 133 toward the rear side of the seat backrest 1. Thus, the settings of the first guide outlet 131 and the second guide outlet 133 ensure the stability and reliability of the first adjustment strap 211 and the second adjustment strap 221 during the leading-out process, and avoid the adjustment straps being wound or stuck during the adjustment process.

[0045] Specifically, as Figure 1As shown, on the lateral outside of the backrest frame 11, on the right side in the left-right direction as shown in the figure, an outer wing frame 12 is provided. The outer wing frame 12 increases the support area of the backrest, making it more stable and capable of providing better back support. For example, Figure 2 As shown, a first strap outlet retaining bracket 13 can be fixedly connected below the outer wing frame 12. The first strap outlet retaining bracket 13 is provided with a first guide outlet 131 that penetrates obliquely from front to back. In this way, it is beneficial for the first adjustment strap 211 to extend obliquely forward along the first guide outlet 131 and be exposed above the surface of the seat cushion, so as to adapt to the hand operation space when the occupant is sitting and facilitate the occupant to pull the first adjustment strap 211.

[0046] It should be noted that the first strap outlet retaining bracket 13 and the second strap outlet retaining bracket 132 can also be flexibly arranged at other positions of the seat backrest 1, such as the lower left position, the lower right position, etc., so as to flexibly change the positions of the first adjustment strap 211 and the second adjustment strap 221, which is convenient for the passengers to use and can be flexibly adjusted according to actual needs.

[0047] And the second strap outlet retaining bracket 132 is fixedly connected above the outer wing frame 12. The first strap outlet retaining bracket 13 is provided with a second guide outlet 133 that penetrates from front to back, so that the second adjustment strap 221 can extend backward from the second guide outlet 133 and be exposed on the back of the seat to adapt to the operation space behind the occupant and facilitate the occupant to pull the second adjustment strap 221. Among them, as Figure 2 As shown, a rear strap limit pin can also be provided on the second strap outlet retaining bracket 132. The rear strap limit pin can rotate relative to the second strap outlet retaining bracket 132, and the second adjustment strap 221 passes through the second guide outlet 133 and is supported above the rear strap limit pin to realize the synchronous rolling when the second adjustment strap 221 expands and contracts, thereby reducing the movement resistance of the second adjustment strap 221 and making it more labor-saving to adjust the second adjustment strap 221. In practice, the rear strap limit pin can be integrally arranged on the second strap outlet retaining bracket 132 through a pin shaft for rotation.

[0048] In actual design, the outer wing frame 12 can be connected to the backrest frame 11, the first strap outlet retaining bracket 13, the second strap outlet retaining bracket 132 and the outer wing frame 12 by welding to improve the connection reliability and stability, thereby improving the reliability of the vehicle seat 100.

[0049] In some embodiments, the outer wing frame 12 is further provided with a first unlocking cable bracket 14, and / or the backrest frame 11 is provided with a second unlocking cable bracket 15. The first unlocking cable bracket 14 and the second unlocking cable bracket 15 are used to fix the extension directions of the first unlocking cable 212 and the second unlocking cable 222. For example, Figure 2As shown, the first unlocking cable bracket 14 extends obliquely and is fixedly connected to the outer wing frame 12. The second unlocking cable bracket 15 is horizontally arranged and fixedly connected to the backrest frame 11. Thus, the cable head of the first unlocking cable 212 can extend obliquely upward and backward, and the cable head of the second unlocking cable 222 can extend downward and inward, which is conducive to the connection of the other ends of the first unlocking cable 212 and the second unlocking cable 222 to the labor-saving mechanism pull rod 24.

[0050] The first unlocking cable bracket 14 is formed with a first groove, and the cable head of the first unlocking cable 212 is clamped in the first groove. The second unlocking cable bracket 15 is formed with a second groove, and the cable head of the second unlocking cable 222 is clamped in the second groove. That is to say, the shape and size of the first groove and the shape and size of the second groove should be respectively adapted to the shape and size of the cable head of the first unlocking cable 212 and the shape and size of the cable head of the first unlocking cable 212, so that the cable head can be stably clamped in the corresponding groove.

[0051] Thus, through the clamping setting of the cable head and the groove, the cable head can be easily inserted and pulled out, which is convenient for the installation and disassembly of the unlocking cable. At the same time, the installation stability of the cable head is ensured, the stability of the unlocking cable during the adjustment process is ensured, and the clamping setting can also reduce the wear and damage of the cable head during use, improve the safety of seat use and extend the service life, and ensure the stability of the unlocking cable during the adjustment process. Of course, the cable bracket and the cable head can also be connected by other connection methods such as bolt connection.

[0052] In some embodiments, the backrest frame 11 is provided with a cable integrated bracket 16. The cable integrated bracket 16 is formed with a first through hole 161 and a second through hole 162. The first unlocking cable 212 passes through the first through hole 161 to be connected to the labor-saving mechanism pull rod 24, and the second unlocking cable 222 passes through the second through hole 162 to be connected to the labor-saving mechanism pull rod 24. The opening direction of the first through hole 161 is parallel to the opening direction of the second through hole 162.

[0053] Specifically, the cable integrated bracket 16 is used to fixedly connect the cable heads of the first unlocking cable 212 and the second unlocking cable 222. As Figure 1 and Figure 2 shown, a backrest central support frame 18 is arranged between the backrest frames 11 to support and fix the cable integrated bracket 16. The cable integrated bracket 16 can be constructed as a bent L-shaped plate, installed at the middle area position of the seat backrest 1, and can be fixedly welded to the backrest central support frame 18 to improve the installation stability of the cable integrated bracket 16.

[0054] Among them, a first through hole 161 adapted to the shape and size of the cable head of the first unlocking cable 212 and a second through hole 162 adapted to the shape and size of the cable head of the second unlocking cable 222 are provided on the lower end surface of the cable integration bracket 16 for fixing the key path directions of the two unlocking cables inside the seat backrest 1. For example, Figure 2 As shown, both the first through hole 161 and the second through hole 162 penetrate vertically. In this way, the two unlocking cables can be threaded through the corresponding through holes from top to bottom and extend downward to be connected to the labor-saving mechanism pull rod 24. In practice, after the two unlocking cables pass through the cable integration bracket 16, that is, after passing through the two through holes, the cable heads at the ends of the two unlocking cables away from the adjusting strap can be clamped to one end of the labor-saving mechanism pull rod 24. That is, a clamping groove adapted to the cable head is provided at one end of the labor-saving mechanism pull rod 24, and the cable head is clamped into the clamping groove to achieve clamping connection, ensuring that the two unlocking cables are firmly connected to the labor-saving mechanism pull rod 24. Thus, when any one of the two unlocking cables is pulled, the labor-saving mechanism pull rod 24 can be driven to rotate.

[0055] And as Figure 2 shown, the opening direction of the first through hole 161 is parallel to the opening direction of the second through hole 162, that is, the first through hole 161 and the second through hole 162 have the same orientation on the lower end surface of the cable integration bracket 16. Thus, the first unlocking cable 212 and the second unlocking cable 222 can be threaded through the first through hole 161 and the second through hole 162 in parallel, avoiding the first unlocking cable 212 and the second unlocking cable 222 from crossing and winding, which affects the adjustment of the seat backrest 1.

[0056] Among them, it should be noted that the first unlocking cable 212 and the second unlocking cable 222 can also be combined into one unlocking cable, so that a through hole can be provided in the cable integration bracket 16, and the unlocking cable is fixedly connected to the labor-saving mechanism pull rod 24 after passing through the through hole.

[0057] In some embodiments, the labor-saving mechanism pull rod 24 is connected with an elastic reset member 241. Both the first locking assembly 21 and the second locking assembly 22 are used to pull the labor-saving mechanism pull rod 24 to rotate around a first direction, and the elastic reset member 241 is used to pull the labor-saving mechanism pull rod 24 to rotate around a second direction.

[0058] Specifically, the elastic reset member 241 has a certain elasticity and can be constructed as a spring, an elastic band or other structural members that can return to the initial state after deformation. The elastic telescopic force of the elastic reset member 241 can be used to make the labor-saving mechanism rotate around the second direction and return to the initial position after being pulled by the first locking assembly 21 or the second locking assembly 22 to rotate around the first direction, that is, when the locking assembly no longer applies a pulling force to the labor-saving mechanism pull rod 24. Among them, the first direction and the second direction are opposite directions.

[0059] like Figure 1 As shown, the elastic return member 241 is constructed as a spring, which is placed vertically along the axial direction and one end is fixed on the labor-saving mechanism rod 24. As a result, the first zipper assembly 21 or the second zipper assembly 22 pulls the labor-saving mechanism rod 24 to rotate around the first direction, that is, when it rotates relatively upward as shown in the figure, at this time, the rotation of the labor-saving mechanism rod 24 causes the elastic return member 241 to be stretched, thereby realizing the unlocking of the vehicle seat 100 to adjust the seat back 1. After completing the rotation around the first direction, that is, when no tension is applied to the first zipper assembly 21 or the second zipper assembly 22, the elastic force of the elastic return member 241 to restore the initial state is utilized, so that the elastic return member 241 can pull the labor-saving mechanism rod 24 to rotate around the second direction opposite to the first direction, that is, when it rotates relatively downward as shown in the figure, the automatic reset of the labor-saving mechanism rod 24 after the unlocking is completed is realized, thereby improving the labor-saving effect.

[0060] In some embodiments, the transmission assembly 25 also includes a recliner unlocking cable 251 and a recliner synchronization shaft 252. The recliner synchronization shaft 252 is connected to the recliner 23 and rotates synchronously with the recliner 23 to ensure that the recliner 23 can rotate smoothly when adjusting the angle, thereby ensuring the stability and accuracy of the recliner 23 during the adjustment process. The recliner synchronization shaft 252 is provided with a recliner unlocking piece 253. One end of the recliner unlocking cable 251 is connected to the labor-saving mechanism pull rod 24 and the other end is connected to the recliner unlocking piece 253. As a result, the transmission assemblies 25 are connected to each other, which is conducive to the transmission of force.

[0061] Specifically, the recliner 23 includes a locking mechanism that can be in a locked state, which is used to fix the position of the seat back 1 after the angle is adjusted. The recliner unlocking cable 251 in the transmission assembly 25 is used to connect the labor-saving mechanism pull rod 24 and the recliner unlocking piece 253, so that the force of the labor-saving mechanism pull rod 24 can be transmitted to the recliner unlocking piece 253, driving the recliner unlocking cable 251 to move, and then applying force to the recliner unlocking piece 253, releasing the locking state of the recliner 23, so that it can be freely adjusted. At this time, the recliner unlocking cable 251 can drive the recliner synchronizing shaft 252 to rotate synchronously with the recliner 23, thereby finally unlocking the recliner 23 and putting it in an unlocked state. The seat back 1 can be adjusted in angle or laid down. After the angle adjustment is completed, that is, the first adjustment strap 211 or the second adjustment strap 221 is released, the recliner unlocking piece 253 and the force-saving mechanism pull rod 24 will be reset, and the recliner 23 will be locked again and restored to the locked state, so that the seat back 1 is in a stable state.

[0062] like Figure 2As shown, the cable head at the upper end of the recliner unlocking cable 251 is clamped and connected to one end of the labor-saving mechanism pull rod 24 away from the first unlocking cable 212 and the second unlocking cable 222, realizing the stable and reliable connection between the recliner unlocking cable 251 and the labor-saving mechanism pull rod 24. The cable head at the lower end of the recliner unlocking cable 251 is clamped and connected to the recliner unlocking piece 253. That is, the recliner unlocking piece 253 is provided with a card slot adapted to the cable head, and the cable head is clamped into the card slot to achieve the clamped connection. Thus, both ends of the recliner unlocking cable 251 are firmly connected.

[0063] Among them, the recliner unlocking piece 253 can be fixed to the recliner synchronizing shaft 252 by welding, improving the firmness of the recliner unlocking piece 253 and preventing it from falling off the recliner synchronizing shaft 252. Of course, the setting of the recliner synchronizing shaft 252 can also be cancelled, and the recliner unlocking cable 251 can be directly connected to the unlocking structure of the recliner 23.

[0064] In some embodiments, the backrest frame 11 is provided with a labor-saving mechanism bracket 17 for fixedly supporting the labor-saving mechanism pull rod 24. The labor-saving mechanism pull rod 24 is rotatably installed on the labor-saving mechanism bracket 17, that is, one end of the labor-saving mechanism pull rod 24 can be installed on the labor-saving mechanism bracket 17, and the other end can rotate around this end.

[0065] Specifically, as Figure 1 and Figure 2 shown, in the actual design, the labor-saving mechanism bracket 17 can be fixedly installed on the backrest central support frame 18 by welding. In this way, the labor-saving mechanism pull rod 24 of the adjusting mechanism 2 can be installed in the upper central area inside the seat backrest 1, away from the passenger's body, avoiding affecting the riding comfort. Among them, the labor-saving mechanism bracket 17 is provided with a pin hole, and the pin can pass through the pin hole and be integrated on the labor-saving mechanism bracket 17. Correspondingly, a hole corresponding to the pin hole can be provided at one end of the labor-saving mechanism pull rod 24 away from the first unlocking cable 212 and the second unlocking cable 222. Thus, the pin can pass through the labor-saving mechanism pull rod 24 and the labor-saving mechanism bracket 17 in sequence to connect the two, and the labor-saving mechanism pull rod 24 is sleeved outside the pin and can rotate around the pin shaft.

[0066] The labor-saving mechanism bracket 17 is provided with a first limiting member 171 and a second limiting member 172. The labor-saving mechanism pull rod 24 is adapted to press against the first limiting member 171 when rotating to the limit position along the first direction, and the labor-saving mechanism pull rod 24 is adapted to press against the second limiting member 172 when rotating to the limit position along the second direction. Thus, the movement position of the labor-saving mechanism pull rod 24 can be restricted, so that the labor-saving mechanism pull rod 24 can move between the distances between the first limiting member 171 and the second limiting member 172, preventing the labor-saving mechanism pull rod 24 from exceeding the movement range of this distance and causing damage.

[0067] Specifically, asFigure 1 and Figure 2 As shown in Figure 2 , the labor-saving mechanism bracket 17 is formed with bent upper and lower end faces. A first limiting member 171 is provided on the upper end face to limit the upward rotation position of the labor-saving mechanism pull rod 24, that is, the labor-saving mechanism pull rod 24 can rotate upward to abut against the second limiting member 172 to prevent it from continuing to move upward excessively. The lower end face of the labor-saving mechanism bracket 17 extends obliquely upward to form an end face, on which a second limiting member 172 is provided to limit the downward rotation position of the labor-saving mechanism pull rod 24, that is, the labor-saving mechanism pull rod 24 can rotate downward to abut against the second limiting member 172 to prevent it from continuing to move downward excessively.

[0068] In actual design, the first limiting member 171 and the second limiting member 172 can be snapped onto the labor-saving mechanism bracket 17 to realize limiting the uppermost movement position and the lowermost movement position of the pull rod, improving convenience. In this way, when the first limiting member 171 and the second limiting member 172 are damaged or excessively worn, they are convenient to replace.

[0069] and as Figure 1 shown, the upper part of the angle adjuster unlocking cable 251 can be snapped onto the third groove 173 of the labor-saving mechanism bracket 17 to maintain the path direction of the upper end of the angle adjuster unlocking cable 251. The upper part of the angle adjuster unlocking cable 251 can be snapped onto the lower crossbeam bracket 19 of the backrest frame 11 to maintain the path direction of the lower end of the angle adjuster unlocking cable 251. The upper end of the elastic reset member 241 is fixedly installed on the labor-saving mechanism pull rod 24, and the lower end of the elastic reset member 241 is fixedly installed on the labor-saving mechanism bracket 17 to realize the fixed installation of the elastic reset member 241.
