[0061] The present application provides an adjusting assembly.

[0062] Please refer to Figure 1 and Figure 2 In an embodiment of the present application, the adjusting assembly comprises a first support 100 and a limiting piece 400, the first support 100 is provided with two groove groups 110 along a first direction, each groove group 110 comprises a plurality of limiting grooves 120 arranged along an adjusting direction, the limiting piece 400 is movably arranged relative to the first support 100 along the adjusting direction, the limiting piece 400 comprises two limiting parts 411 arranged along the first direction and elastically connected, each limiting part 411 is selectively clamped in a limiting groove 120 in a groove group 110, the limiting grooves 120 clamped by the two limiting parts 411 are oppositely arranged along the first direction, and the openings of the limiting grooves 120 along the first direction are oppositely directed. Preferably, the first direction and the adjusting direction are two directions forming an angle, and the angle is perpendicular or approximately perpendicular.

[0063] Thus, the limiting piece 400 moves along the adjusting direction relative to the first support 100, and the relative position of the limiting part 411 and the plurality of limiting grooves 120 can be changed. The limiting part 411 is clamped into different limiting grooves 120, so that the limiting piece 400 and the first support 100 are locked at different positions. For two structural members that need to adjust the relative position, one is fixedly connected with the first support 100, and the other is fixedly connected with the limiting piece 400. The fixedly connected manner can be direct connection, indirect connection or integral molding. Among them, the structural member fixedly connected with the first support 100 on the side of the limiting piece 400 can be a fixed member, and the structural member fixedly connected with the limiting piece 400 on the side of the first support 100 can be a movable member. Alternatively, the structural member fixedly connected with the first support 100 on the side of the limiting piece 400 can be a movable member, and the structural member fixedly connected with the limiting piece 400 on the side of the first support 100 can be a fixed member. Alternatively, both structural members can be movable members. For convenience of description, the following description will be based on the first case, and the other two cases can be referred to accordingly.

[0064] It can be understood that the plurality of limiting grooves 120 of the two groove groups 110 are arranged one by one in correspondence, and the opening directions are both the first direction, but the opening directions are opposite, that is, the openings of the limiting grooves 120 of the two groove groups 110 can be opened in the first direction towards each other or away from each other. Based on this, when the two limiting parts 411 are disengaged from the limiting grooves 120, they need to move towards each other or away from each other, so that the relative position between the two limiting parts 411 changes. Due to the elastic connection between the two limiting parts 411, the change of the relative position of the two limiting parts 411 needs to overcome the elastic force. That is, without external force, the limiting part 411 can be stably clamped in the limiting groove 120 due to the elastic connection between the two limiting parts 411, so that the limiting piece 400 can be locked with the first support 100 at the current position. Among them, when the two limiting parts 411 are clamped in the limiting groove 120, the two limiting parts 411 can have no elastic force, or can have a certain elastic pre-tightening force. Under the action of the elastic pre-tightening force, the limiting part 411 can be more stably clamped in the limiting groove 120.

[0065] Specifically, when the two slot groups 110 have the slot openings of the limiting grooves 120 facing each other, and the two limiting portions 411 are respectively clamped in the corresponding limiting grooves 120, the two limiting portions 411 can not have elastic force or have a certain elastic compression pre-tightening force between them, at this time, when the two limiting portions 411 move in the direction away from the corresponding limiting grooves 120, the distance between the two limiting portions 411 is reduced, resulting in an increase in the elastic compression force between the two limiting portions 411, thereby having a tendency to move away from each other. When the limiting clamping piece 400 moves a certain distance in the adjusting direction relative to the first support 100, so that the two limiting portions 411 are opposite to another limiting groove 120, under the action of the elastic compression force, the two limiting portions 411 will move away from each other, thereby being clamped into the opposite limiting groove 120. When the slot openings of the limiting grooves 120 of the two slot groups 110 are arranged opposite to each other, the elastic force between the two limiting portions 411 is generated by stretching, which becomes an elastic tension force, and the related matching process is referred to, which will not be described here.

[0066] In the technical scheme of the present application, by matching the two limiting portions 411 with the limiting grooves 120 of different slot groups 110, locking force can be provided in two opposite directions, thereby improving the locking effect. Further, the two limiting portions 411 are elastically connected, and on the basis of reliably providing locking force for the clamping of the limiting portions 411 and the limiting grooves 120 by the elastic force, since the two limiting portions 411 are matched with the corresponding limiting grooves 120 from opposite directions and the elastic forces acting on the two limiting portions 411 are opposite, the two limiting portions 411 can restrict each other from being separated from the limiting grooves 120, thereby further improving the locking effect.

[0067] In an embodiment, please refer to Figure 5 The limiting groove 120 is configured as a ratchet groove. That is, the limiting groove 120 has a limiting groove wall 121 and a guide groove wall 122 opposite in the adjusting direction, wherein the guide groove wall 122 is an inclined groove wall, and the limiting groove wall 121 can be a straight groove wall or an inclined groove wall inclined in the same direction as the guide groove wall 122. In this way, when the limiting portion 411 is clamped in the limiting groove 120, if the limiting portion 411 moves towards the side where the limiting groove wall 121 is located, it will be blocked by the limiting groove wall 121, and if the limiting portion 411 moves towards the side where the guide groove wall 122 is located, it can slide out of the limiting groove 120 along the guide groove wall 122.

[0068] Based on this, the distribution directions of the limiting groove wall 121 and the guide groove wall 122 can be arranged based on the direction of the external force acting on the adjusting assembly, so as to improve the practicability of the adjusting assembly. For the convenience of the following description, the direction from the limiting groove wall 121 to the guide groove wall 122 in the adjusting direction is referred to as the first adjusting direction, and the direction from the guide groove wall 122 to the limiting groove wall 121 in the adjusting direction is referred to as the second adjusting direction.

[0069] First, the limiting effect of the limiting groove wall 121 on the limiting portion 411 can ensure that the adjustment assembly has sufficient resistance to external forces, thereby providing a certain support capacity, so that when the adjustment assembly is in place, it can provide support for related structures or related parts of the user. Specifically, based on the limiting cooperation between the limiting groove wall 121 and the limiting portion 411, a support force in the second adjustment direction can be provided to the external structure on the side of the first bracket 100, and a support force in the first adjustment direction can be provided to the external structure on the side of the limiting clamp 400.

[0070] Second, in the initial state of the adjustment component, such as Figure 5 As shown, the limiting portion 411 and its corresponding slot group 110 can be distributed sequentially along the first adjustment direction. This position is also the initial position of the limiting clamp 400. At this time, for each limiting slot 120, the limiting slot wall 121 will be located on the side of the guide slot wall 122 close to the limiting portion 411. When the limiting clamp 400 moves relative to the first bracket 100 along the first adjustment direction from the initial position, the limiting portion 411 will also sequentially enter and exit each limiting slot 120 on the motion path along the first adjustment direction, and finally engage with the limiting slot 120 corresponding to the target position. Specifically, when the limiting portion 411 is inserted into a limiting slot 120, due to the relative movement of the limiting clamp 400 and the first bracket 100, the limiting portion 411 will slide out of the notch of the limiting slot 120 along the guide slot wall 122. During this process, the elastic potential energy between the two limiting portions 411 increases. Then, the limiting portion 411 continues to move along the first adjustment direction until it passes over the limiting groove wall 121 of the next limiting groove 120. Under the action of the elastic force, the limiting portion 411 will be bounced into the limiting groove 120. After that, the cooperation between the limiting portion 411 and the limiting groove 120 will be cyclical according to this process until the limiting portion 411 is stuck in the limiting groove 120 at the target position.

[0071] In other embodiments, the limiting groove 120 may also be configured as other structural shapes as needed, and the two side walls may also be configured as straight groove walls, or as inclined groove walls inclined in opposite directions.

[0072] In one embodiment, the adjustment assembly also includes a second bracket 200, which is movably connected to the first bracket 100 in the adjustment direction. The limiting clamp 400 includes a first elastic member 420 and two limiting members 410 connected by the first elastic member 420. Each limiting member 410 is correspondingly provided with a limiting portion 411, and the limiting member 410 is movably installed on the first bracket 100.

[0073] Thus, the second support 200 can provide a stable installation environment for each part of the limiting clamp 400, and the second support 200 can also facilitate the connection of external structural components, and the connection reliability of the two can be guaranteed. In the embodiment, the limiting member 410 can be driven by the second support 200 to move in the adjusting direction relative to the first support 100, so as to drive the limiting part 411 to move to the position of the different limiting grooves 120. The movable connection of the limiting member 410 and the second support 200 enables the limiting part 411 to move relative to the second support 200 in at least the first direction, so as to provide displacement of the limiting part 411 clamped into or separated from the limiting groove 120.

[0074] The first elastic member 420 can be a spring, a rubber elastic body, a silica gel elastic body, etc. By arranging the first elastic member 420 between the two limiting members 410, reliable elastic connection between the two limiting members 410 can be achieved. It should be noted that the arrangement position of the first elastic member 420 needs to enable the first elastic member 420 to sense the relative position change between the two limiting parts 411, that is, when the two limiting parts 411 move in opposite directions in the first direction, the first elastic member 420 can elastically deform and transmit opposite elastic force to the two limiting parts 411, thereby the first elastic member 420 can provide locking force to lock the limiting part 411 in the limiting groove 120. Of course, one first elastic member 420 can also be arranged between each limiting member 410 and the second support 200, and the first elastic member 420 can correspondingly provide locking force for one limiting member 410.

[0075] In other embodiments, the two limiting parts 411 can be formed on an integrally formed member, and the two limiting parts 411 are elastically connected through elastic support arms. The integrally formed member can be a plastic member or a metal member, which has elasticity within a certain deformation range and is fixedly connected with the external structural component.

[0076] In an embodiment, please refer to Figure 3 and Figure 4The limiting member 410 comprises a rotating portion 412 and a connecting arm 413, the rotating portion 412 is rotatably connected to the second support 200, and the rotating portion 412 and the limiting portion 411 are respectively arranged at two ends of the connecting arm 413. In this way, when the second support 200 moves in the adjusting direction, the limiting member 410 can be driven to move along with the position connected with the rotating portion 412, and the displacement of the limiting portion 411 in the first direction in and out of the limiting slot 120 can be realized by rotating the limiting member 410 around the rotating portion 412, that is, through the rotating cooperation of the limiting member 410 and the second support 200, the limiting member 410 can be driven by the second support 200 in the adjusting direction, so that the limiting portion 411 can be opposite to different limiting slots 120, and at the same time, the freedom of the limiting portion 411 moving in the first direction relative to the second support 200 is retained, so that the limiting portion 411 can move in and out of the limiting slot 120. Further, the first elastic member 420 is arranged close to the limiting portion 411 to ensure that the first elastic member 420 can reliably provide elastic force to the two limiting portions 411. In other embodiments, the limiting portion 411 can be slidably connected to the second support 200 in the first direction.

[0077] The limiting portion 411 is protruded on the connecting arm 413, wherein the protruding direction of the limiting portion 411, the first direction and the adjusting direction are three directions not coplanar, and it is appropriate that they are perpendicular to each other. In other embodiments, the limiting portion 411 can be protruded on the connecting arm 413 in the first direction, and the limiting portions 411 of the two limiting members 410 can be protruded towards each other or away from each other.

[0078] Further, please participate Figure 2 and Figure 4 The first support 100 is provided with a containing slot 210, the limiting clamping member 400 is accommodated in the containing slot 210, and the containing slot 210 has a rotating cooperation position 211, and the rotating portion 412 is rotatably clamped in the rotating cooperation position 211. In this way, the limiting clamping member 400 is equivalent to being embedded on the first support 100, which can reduce the occupied space of the adjusting assembly, so as to facilitate the installation of the adjusting assembly. Moreover, the containing slot 210 can rotatably clamp the rotating portion 412 through the slot wall at the rotating cooperation position 211, and on the opposite sides of the two limiting members 410, the slot wall can also abut against the limiting member 410, which is conducive to ensuring the installation stability of the limiting clamping member 400. In other embodiments, the first support 100 and the limiting clamping member 400 can be arranged in a stack, the first support 100 is provided with a rotating shaft protruding portion which is inserted into the shaft hole of the limiting member 410 to realize rotatable connection.

[0079] In an embodiment, please refer to Figure 5 and Figure 6The adjusting assembly further comprises a third support 300, the second support 200 and the third support 300 are relatively movable in the adjusting direction; the third support 300 is formed with a matching groove 310, the limiting part 411 is inserted into the matching groove 310, the matching groove 310 comprises a first groove position 311 and a second groove position 312 which are in communication, the second groove position 312 is located on one side of the first groove position 311 in the adjusting direction; when the limiting part 411 is engaged with the limiting groove 120, the limiting part 411 is located in the first groove position 311; after the limiting part 411 is disengaged from the limiting groove 120, the limiting part 411 can be limitedly matched with the second groove position 312 in the first direction.

[0080] Specifically, when the limiting part 411 is located in the first groove position 311, the active matching between the limiting part 411 and the first groove position 311 can meet the switching of the limiting part 411 between the state of being engaged with the limiting groove 120 and the state of being disengaged from the limiting groove 120; after the limiting part 411 is disengaged from the limiting groove 120, the limiting part 411 can move to the position opposite to the second groove position 312 in the first groove position 311. At this time, the relative movement of the second support 200 and the third support 300 in the adjusting direction can make the limiting part 411 enter the second groove position 312 and be limited in the first direction. It can be understood that the limiting part 411 will be subjected to the action of the elastic force on one side in the first direction, and based on this, the limiting part 411 can abut against the groove wall at the second groove position 312 on the other side. Of course, the limiting part 411 can abut against the two groove walls at the second groove position 312 on the opposite sides in the first direction.

[0081] It can be understood that when the limiting part 411 is located in the second groove position 312, it will be maintained in the state of being disengaged from the limiting groove 120, that is, the limiting part 411 located in the second groove position 312 will not be engaged into the limiting groove 120, and the limiting part 411 can be matched with the first support 100 with a gap or abut against it. In this way, when the second support 200 drives the limiting part 411 to move along the adjusting direction, the limiting part 411 will not be interfered by the first support 100.

[0082] In this way, when the relative positions of the first support 100 and the second support 200 are adjusted, the limiting part 411 can be driven to enter the second groove position 312, and after the relative positions of the two supports are adjusted to the right position, the limiting part 411 will be opposite to one of the limiting grooves 120, and then the relative movement of the second support 200 and the third support 300 is driven to make the limiting part 411 enter the first groove position 311, so that the limiting part 411 can enter the corresponding limiting groove 120 under the action of the elastic force, thereby locking the first support 100 and the second support 200 at the current position.

[0083] When the limiting grooves 120 are configured as the above-mentioned ratchet grooves, the limiting piece 400 also has a terminal position, and in the adjusting direction, the plurality of limiting grooves 120 of the groove set 110 are located between the limiting portion 411 in the initial position and the limiting portion 411 in the terminal position. When the limiting piece 400 moves from the initial position to the terminal position, please refer to Figure 12 and Figure 13 , the limiting portion 411 is always located in the first groove position 311, and when the limiting piece 400 moves to the terminal position, please refer to Figure 14 , the limiting portion 411 is also withdrawn from the last limiting groove 120 and abuts against the side wall of the first support 100. At this time, the limiting portion 411 located in the first groove position 311 is moved to a position opposite to the second groove position 312, please refer to Figure 15 , and thereafter, driving the second support 200 and the third support 300 to move relatively can make the limiting portion 411 enter the second groove position 312. Please refer to Figure 16 , and thereafter, when the second support 200 drives the limiting piece 400 to reset to the initial position, the limiting portion 411 will be limited to fall into the limiting groove 120, that is, will not be interfered by the limiting groove wall 121.

[0084] Among them, the second support 200 is formed with a slot 220, and the third support 300 has a plug-in portion 320 which is inserted into the slot 220, and in the adjusting direction, the width of the slot 220 is greater than the width of the plug-in portion 320.

[0085] That is, in the adjusting direction, there is a cooperation gap between the plug-in portion 320 and the slot 220, which enables the second support 200 and the third support 300 to move relatively within a certain range in the adjusting direction, so that the second support 200 can drive the limiting portion 411 to switch between the first groove position 311 and the second groove position 312. It can be understood that in the adjusting direction, the relative movement stroke of the second support 200 and the third support 300 will have two extreme points, and when reaching the two extreme points, the second support 200 can drive the third support 300 to move in one direction in the adjusting direction.

[0086] Among them, it can be that the slot wall of the slot 220 pushes the plug-in portion 320, or that the limiting portion 411 pushes the slot wall of the cooperation groove 310 to realize the driving of the third support 300 by the second support 200.

[0087] Specifically, the first groove position 311 and the second groove position 312 are distributed in the second adjusting direction in turn, that is, the distribution direction from the first groove position 311 to the second groove position 312 is the same as the distribution direction from the terminal position to the initial position.

[0088] Thus, when the second support 200 drives the limiting part 411 to move to the terminal position and then reversely moves to reset to the initial position, the third support 300 first stays in the original position, that is, the second support 200 and the third support 300 first relatively move until the limiting part 411 enters the second slot 312 and abuts against the end wall of the second slot 312, and then the end wall of the second slot 312 is pushed by the limiting part 411, thereby driving the third support 300 to move.

[0089] In the resetting process to the initial position, the second support 200 first drives the limiting part 411 to appropriately pass the initial position and then reversely moves to the initial position, and when the second support 200 reversely moves, the third support 300 first stays in the original position, that is, the second support 200 and the third support 300 first relatively move, and in this process, the limiting part 411 slides out of the second slot 312 to the first slot 311 and moves to a position away from the second slot 312 under the elastic force of the elastic member, thereby reaching the initial position, that is, switching from the state of Figure 17 to the state of Figure 12 At this time, the second support 200 abuts against the plug-in part 320 of the third support 300 through the push wall 221 of the insertion slot 220, and thus, when the second support 200 drives the limiting part 411 to move from the initial position to the terminal position, the plug-in part 320 is always pushed by the push wall 221 of the insertion slot 220, thereby driving the third support 300 to move.

[0090] In an embodiment, the third support 300 and the first support 100 are damp matched, that is, there is a friction force between the third support 300 and the first support 100, so that the third support 300 can keep still with the first support 100 without external force, and thus, the third support 300 can stay in the original position in the initial stage of the reverse movement of the first support 100, and only when the third support 300 is pushed by the second support 200 through the corresponding structure, the third support 300 is driven to move.

[0091] Specifically, please refer to Figure 2 and Figure 9The third support 300 is provided with a plug-in part 320 on each side in the first direction, and the two plug-in parts 320 are respectively abutted against the first support 100, or the opposite sides of the two plug-in parts 320 are respectively abutted against the first support 100. In this way, through the abutment and cooperation of the two plug-in parts 320 and the first support 100, the two plug-in parts 320 will be respectively subjected to the action force of the first support 100 in the opposite direction, so that the third support 300 can reliably produce the effect of interference fit with the first support 100, and ensure that the two plug-in parts 320 can be subjected to greater pressure, and the plug-in part 320 and the first support 100 can generate a certain friction force, so that the opposite sides of the third support 300 in the first direction can be reliably damped and cooperated with the first support 100.

[0092] It can be understood that the first support 100 is also formed with a avoiding groove 170, and the plug-in part 320 is abutted against the groove wall of the avoiding groove 170. When the third support 300 is driven by the second support 200, the plug-in part 320 slides along the avoiding groove 170. Among them, one avoiding groove 170 can be provided corresponding to one plug-in part 320, that is, one plug-in part 320 is inserted into one avoiding groove 170, or as shown in Figure 2 the first support 100 is provided with only one avoiding groove 170, and the opposite sides of the two plug-in parts 320 are respectively abutted against the opposite side walls of the avoiding groove 170.

[0093] Among them, the main bodies of the third support 300 and the second support 200 are both plate structures, and the main bodies of the two are relatively and spacedly arranged. The two insertion grooves 220 are respectively arranged on the opposite sides of the second support 200, and the plug-in parts 320 are protruded from the opposite sides of the third support 300 towards the second support 200, so as to be inserted into the insertion grooves 220 and the avoiding grooves 170. The distribution direction of the second support 200 and the third support 300 is parallel or substantially parallel to the protruding direction of the limiting part 411, and the accommodating groove 210 is arranged through the second support 200 in the direction, so as to facilitate the installation of the limiting clamping part 400. The second support 200 is provided with an enclosing plate 500 on the opposite side of the third support 300, and the enclosing plate 500 and the third support 300 are both arranged opposite to the accommodating groove 210 and cover and block the accommodating groove 210 on both sides respectively. The limiting part 411 is protruded towards the side where the third support 300 is located, so as to be inserted into the cooperating groove 310.

[0094] Further, the two plug-in parts 320 are inclined to extend away from or close to each other, so that sufficient static friction between the plug-in part 320 and the first support 100 is ensured under the premise of reliable abutment between the plug-in part 320 and the first support 100, thereby ensuring the damping cooperation effect of the two, and also reducing the contact area of the plug-in part 320 and the first support 100 to reduce the sliding friction between the third support 300 and the first support 100, so that the second support 200 can drive the third support 300 more labor-savingly.

[0095] Further, please refer to Figure 2 , Figure 7 and Figure 9 , the first support 100 includes oppositely arranged first and second frame bodies 101 and 102, and the second support 200 and the third support 300 are clamped between the first and second frame bodies 101 and 102, that is, the first frame body 101, the second support 200, the third support 300 and the second frame body 102 are sequentially stacked, and the limiting groove 120 is formed in the first frame body 101, and the avoiding groove 170 is formed in the second frame body 102.

[0096] In an embodiment, please refer to Figure 1 , the side of the first support 100 is formed with a guide groove 140 extending in the adjusting direction, and the side of the second support 200 is slidably connected to the guide groove 140. In this way, the relative movement of the second support 200 and the third support 300 in the adjusting direction can be guided by the guide groove 140 to improve the adjusting reliability of the adjusting assembly.

[0097] Among them, please refer to Figure 2 and Figure 8 , the side of the second support 200 is provided with a rolling member 230, which can be a ball or a roller, and is rollably installed on the side of the second support 200. By rolling the rolling member 230 in the guide groove 140, the friction force received by the second support 200 will be converted into rolling friction, thereby reducing the friction force received by the second support 200, so that the second support 200 can move more labor-savingly and smoothly.

[0098] Among them, the guide groove 140 is provided with an abutting member 150, one side of the abutting member 150 is matched with the guide groove 140 through a second elastic member 160, and the other side abuts against the side of the second support 200. Among them, the second elastic member 160 can be a spring, an elastic body of rubber or silicone material, a metal spring piece, etc. The second elastic member 160 is located between the abutting member 150 and the groove wall of the guide groove 140, and the opposite ends are respectively abutted against the abutting member 150 and the groove wall of the guide groove 140. The side of the second support 200 can abut against the abutting member 150 through the rolling member 230, or can abut against the abutting member 150 through the convex arc-shaped convex part.

[0099] Thus, the cooperation gap between the first support 100 and the second support 200 can be absorbed by the second elastic member 160, that is, according to the depth of the second support 200 entering the guide groove 140, the second elastic member 160 can adaptively deform to adjust the position of the abutting member 150, so as to guarantee the guide cooperation of the first support 100 and the second support 200. In addition, when the second support 200 and the first support 100 move relative to each other, the second elastic member 160 can play a buffering role, absorb shock and impact force, improve the movement stability of the second support 200, effectively reduce the rigid collision between components, reduce wear and tear, and help to improve the service life of the adjusting assembly.

[0100] Further, the rolling members 230 and the second elastic members 160 are distributed in the adjusting direction, the abutting member 150 extends in the adjusting direction and is provided with bent ear portions at both ends, the ear portions are provided with adjusting holes and are hung on the protrusions provided on the first support 100, so as to guarantee that the abutting member 150 is reliably connected to the first support 100 and can be movably arranged in the guide groove 140. The two guide grooves 140 are distributed relative to each other in the first direction, and the opposite sides of the second support 200 are respectively inserted into the two guide grooves 140 and are guided and cooperated in the two guide grooves 140, so as to guarantee the movement stability of the second support 200.

[0101] In other embodiments, one side of the rolling member 230 can be cooperated with the second support 200 through an elastic member, and the other side can be rollingly cooperated with the groove wall of the guide groove 140.

[0102] The headrest adjusting device also includes a headrest and an adjusting assembly, and the specific structure of the adjusting assembly is referred to the above embodiments. Since the headrest adjusting device adopts all the technical solutions of the above embodiments, it at least has all the beneficial effects brought by the technical solutions of the above embodiments, which will not be repeated here.

[0103] Specifically, in the adjusting direction, the headrest 10 is fixedly cooperated with one of the first support 100 and the limiting clamping member 400, and the adjusting direction can be set as the up-down direction or the front-rear direction, so that the user can move and adjust the headrest 10 in the up-down direction or the front-rear direction, so that the position of the headrest 10 can be comfortable for the user to lean on.

[0104] In an embodiment, please refer to Figures 18 to 21The headrest adjusting device comprises two adjusting assemblies, i.e., a first adjusting assembly 21 and a second adjusting assembly 22. The adjusting direction of the first adjusting assembly 21 is the front-rear direction, and the adjusting direction of the second adjusting assembly 22 is the up-down direction. In this way, the front-rear position of the headrest 10 can be adjusted by the first adjusting assembly 21, and the up-down position of the headrest 10 can be adjusted by the second adjusting assembly 22, so as to improve the flexibility of the position adjustment of the headrest 10 and thus guarantee the comfort of the user.

[0105] Specifically, the headrest 10 is drivingly connected to one of the first bracket 100 and the limiting piece 400 of the first adjusting assembly 21, and the first adjusting assembly 21 is drivingly connected to one of the first bracket 100 and the limiting piece 400 of the second adjusting assembly 22. In this way, when the user applies force to the headrest 10 in the front-rear direction, the limiting piece 400 of the first adjusting assembly 21 can be moved in different limiting grooves 120, and when the user applies force to the headrest 10 in the up-down direction, the limiting piece 400 of the second adjusting assembly 22 can be moved in different limiting grooves 120, so as to realize the position adjustment of the headrest 10.

[0106] In an embodiment, the first brackets 100 of the two adjusting assemblies are fixed, and the headrest 10 is fixed to the second bracket 200 of the first adjusting assembly 21. In this way, when the user applies force to the headrest 10 in the front-rear direction, the second bracket 200 of the first adjusting assembly 21 can be driven to move relative to the first bracket 100, so as to adjust the front-rear position of the headrest 10; and when the user applies force to the headrest 10 in the up-down direction, a force transmission path will be formed, which is from the headrest 10 to the second bracket 200 of the first adjusting assembly 21, to the first bracket 100 of the first adjusting assembly 21, and finally to the first bracket 100 of the second adjusting assembly 22, so as to drive the first bracket 100 of the second adjusting assembly 22 to move, thereby adjusting the up-down position of the headrest 10. In other embodiments, the structure to which the headrest 10 is fixed and the structure fixed between the two adjusting assemblies can be other structures, as long as the adjustment of the headrest 10 in the up-down direction and the front-rear direction is not interfered.

[0107] Further, for the first adjusting assembly 21, the first adjusting direction is the forward direction, i.e., the initial position of the headrest 10 corresponds to the most rearward position. When the user pulls the headrest 10 forward, the limiting part 411 can be sequentially moved in different limiting grooves 120. After the front-rear position of the headrest 10 is adjusted, the limiting part 411 will be clamped in a limiting groove 120, and the limiting groove wall 121 of the limiting groove 120 will support the limiting part 411 behind the limiting part 411. In this way, when the user leans against the headrest 10, the user can receive reliable support force from the rear, and the backward pressure applied by the user to the headrest 10 will not cause the headrest 10 to move, so as to guarantee the comfort of the user.

[0108] Similarly, for the second adjusting assembly 22, the first adjusting direction thereof is the upward direction, that is, the initial position of the headrest 10 corresponds to the lowermost position, and the user can pull the headrest 10 upward to drive the limiting part 411 to sequentially pass through different limiting grooves 120, and after the up-down position of the headrest 10 is adjusted to the position, the limiting part 411 is clamped in a limiting groove 120, and the limiting groove wall 121 of the limiting groove 120 supports the limiting part 411 below the limiting part 411, so that when the user leans on the headrest 10, reliable supporting force from below can be obtained, and the downward pressure applied by the user to the headrest 10 after leaning on the headrest 10 will not cause the headrest 10 to move, thereby ensuring the comfort of the user.

[0109] In addition, the user can pull the headrest 10 forward or upward multiple times intermittently, and after the limiting part 411 is clamped in a limiting groove 120, the user can feel the comfort degree of leaning, and decide whether to maintain the headrest 10 at the current position, and each operation does not need to additionally perform unlocking or locking operation, and the adjusting convenience and the reliability of locking the position of the headrest 10 are considered.

It can be understood that the included angle between the two rod segments 31 is about 90 degrees, and the two rod segments 31 are fixed with the first supports 100 of different adjusting assemblies through different rod segments 31, so that the first supports 100 of the two adjusting assemblies are fixed, and the force transmission bridge of the two adjusting assemblies is formed by the two first supports 100,

[0111] Specifically, the first support 100 is provided with a limiting side part 180, and the two rod segments 31 are respectively arranged in the corresponding limiting side part 180, one side of the two rod segments 31 close to each other abuts against the limiting side part 180 through a limiting step 32, and the other side is sleeved with a limiting sleeve ring 33, and the limiting sleeve ring 33 also abuts against the limiting side part 180, so that the limiting side part 180 is clamped between the limiting step 32 and the limiting sleeve ring 33 to realize the fixed connection of the rod segment 31 and the first support 100.

[0112] In other embodiments, the fixed rod 30 can be fixed with the first support 100 by screwing, welding or injection molding.
