[0032] The embodiments of the present application are described in detail below, and the embodiments described with reference to the accompanying drawings are exemplary, and the embodiments of the present application are described in detail below.

[0033] The embodiments of the present application are described in detail below, and the embodiments described with reference to the accompanying drawings are exemplary, and the embodiments of the present application are described in detail below. Figures 1-6 The headrest 100 of the seat according to the embodiments of the present application is described below, and the headrest 100 of the seat can be applied to the seat.

[0034] The headrest 100 of the seat according to the embodiments of the present application is described below, and the headrest 100 of the seat can be applied to the seat. Figures 1-6 As shown in the drawings, the headrest 100 of the seat according to the present application can mainly include a headrest fixing plate 10, a headrest body 20 and a sleeve piece 40.

[0035] The headrest body 20 is arranged at the front side of the headrest fixing plate 10, and the rear end of the headrest body 20 is provided with a first mounting hole 321 extending in the left-right direction. The rear end of the sleeve piece 40 is connected to the headrest fixing plate 10, and the front end of the sleeve piece 40 is provided with a second mounting hole 411 extending in the left-right direction. The second mounting hole 411 corresponds to the first mounting hole 321 and is internally provided with a damping piece 60. The fastener 50 penetrates the damping piece 60 and connects the sleeve piece 40 and the headrest body 20 to be rotatable up and down.

[0036] Specifically, in the front-rear direction, by connecting the sleeve piece 40 between the headrest body 20 and the headrest fixing plate 10, the headrest fixing plate 10 is adapted to be fixedly connected to the seat, so that the fixation of the sleeve piece 40 and even the headrest 100 on the seat can be achieved, and the headrest body 20 can provide additional support for the head and neck of the passenger.

[0037] By setting the first mounting hole 321 extending in the left-right direction at the rear end of the headrest body 20, setting the second mounting hole 411 extending in the left-right direction at the front end of the sleeve member 40, when assembling, only the second mounting hole 411 and the first mounting hole 321 need to be corresponded, then the damping member 60 is arranged in the first mounting hole 321 and the second mounting hole 411, and then the fastener 50 is threaded through the damping member 60 from the left-right direction and fastened, so that the sleeve member 40 and the headrest body 20 can be connected. It can be understood that when the fastener 50 is threaded through the silica gel pad, the second mounting hole 411 and the first mounting hole 321 have been threaded.

[0038] Specifically, the fastener 50 threads through the damping member 60 and connects the sleeve member 40 and the headrest body 20 to be rotatable up and down, that is, force can be applied to the headrest body 20, the fastener 50 is the rotation axis, and the headrest body 20 is rotated relative to the sleeve member 40 in the up-down direction, so that the angle adjustment of the headrest body 20 can be realized, and the angle use demand of different users for the headrest body 20 can be adapted.

[0039] Further, since the damping member 60 is arranged in the first mounting hole 321 and the second mounting hole 411, when the user applies force to the headrest body 20 to rotate the headrest body 20 relative to the sleeve member 40 in the up-down direction, the damping member 60 will generate a damping force on the headrest body 20 and the sleeve member 40, which can resist the gravity or other external force of the headrest body 20, realize the fixation of the angle of the headrest body 20, prevent the headrest body 20 from rotating unintentionally, ensure the stability and reliability of the angle of the headrest body 20, and the structure of the headrest 100 is more simple and reliable, so as to improve the user experience.

[0040] Therefore, by setting the first mounting hole 321 at the rear end of the headrest body 20, setting the second mounting hole 411 at the front end of the sleeve member 40, corresponding the second mounting hole 411 and the first mounting hole 321 and arranging the damping member 60 inside, and threading the fastener 50 through the damping member 60 and connecting the sleeve member 40 and the headrest body 20 to be rotatable up and down, the headrest 100 of the seat not only has adjustable angle, but also has more simple and reliable structure and more convenient and stable operation.

[0041] In combination Figures 3-6 As shown, the headrest 100 of the seat can further include a metal pad 70, the damping member 60 is a silica gel pad, the left and right sides of the rear end of the headrest body 20 are further provided with a first mounting groove 322, the first mounting groove 322 is in communication with the first mounting hole 321, the silica gel pad is at least partially interference-fitted in the first mounting groove 322 and the second mounting hole 411, the metal pad 70 is arranged on the side of the silica gel pad away from the first mounting groove 322, and the fastener 50 is threaded through the metal pad 70 and the silica gel pad in sequence to connect the headrest body 20 and the sleeve member 40.

[0042] Thus, in assembly, the fastener 50 can be sequentially threaded through the metal gasket 70 and the silica gel gasket, and then the headrest body 20 and the sleeve member 40 are connected. The fastener 50 can be a bolt, two bolts, and two nuts 323 can be pre-buried in the first mounting hole 321, so that the two bolts can be sequentially threaded through the metal gasket 70 and the silica gel gasket from the left and right sides, and then connected with the corresponding nuts 323.

[0043] When the user exerts force on the headrest body 20 to rotate the headrest body 20 relative to the sleeve member 40 in the up-down direction, the silica gel gasket has a friction force with the inner wall of the first mounting groove 322 and the inner wall of the first mounting hole 321, respectively, which can resist the gravity of the headrest body 20, realize the fixation of the angle of the headrest body 20, prevent the headrest body 20 from rotating due to gravity, ensure the stability and reliability of the angle of the headrest body 20, and improve the user's experience.

[0044] It should be noted that by providing the metal gasket 70, the silica gel gasket can be prevented from rotating the fastener 50, causing the fastener 50 to loosen, thereby improving the structural reliability of the seat cushion.

[0045] In combination Figures 1-6 As shown, the headrest 100 of the seat can further include a lifting adjustment assembly 30 connected with the headrest body 20 and provided with a first mounting hole 321, the headrest body 20 is provided with a first sliding groove 221 extending in the up-down direction and provided with a plurality of first limiting portions 222, the plurality of first limiting portions 222 are spaced apart in the up-down direction, the lifting adjustment assembly 30 is at least partially disposed in the first sliding groove 221 and is movable relative to the first sliding groove 221 in the up-down direction, the lifting adjustment assembly 30 is provided with a second limiting portion 311, the second limiting portion 311 and one of the plurality of first limiting portions 222 are in limiting cooperation in the up-down direction.

[0046] Specifically, by connecting the lifting adjustment assembly 30 between the headrest fixing plate 10 and the sleeve member 40, the sleeve member 40, the lifting adjustment assembly 30, and even the headrest 100 can be fixed on the seat. And by providing the first mounting hole 321 on the lifting adjustment assembly 30, the angle adjustment of the headrest body 20 can be achieved by the relative rotation of the lifting adjustment assembly 30 and the sleeve member 40.

[0047] By arranging the first sliding groove 221 on the headrest body 20, the first sliding groove 221 is arranged to extend in the up-down direction, and the lifting adjustment assembly 30 is connected with the headrest body 20, the lifting adjustment assembly 30 is at least partially arranged in the first sliding groove 221 and is movable in the up-down direction relative to the first sliding groove 221, so that the user can limit the sliding path of the headrest 100 by applying force to the headrest body 20 to cause the lifting adjustment assembly 30 and the first sliding groove 221 to slide relative to each other in the up-down direction, and realize the relative sliding of the headrest body 20 and the lifting adjustment assembly 30 in the up-down direction.

[0048] Therefore, under the premise of realizing the angle adjustment of the headrest body 20, the height adjustment of the headrest body 20 can be realized, which can facilitate the user to adjust the height of the headrest body 20, and then can adapt to the height use demand of the headrest body 20 of the seat of different users, and improve the user experience.

[0049] Further, by arranging a plurality of first limiting portions 222 in the first sliding groove 221, the plurality of first limiting portions 222 are arranged in the up-down direction, and a second limiting portion 311 is arranged on the lifting adjustment assembly 30, so that after the user adjusts the headrest body 20 to the desired height, the first limiting portion 222 and the second limiting portion 311 can be limited and matched in the up-down direction, realizing the fixation of the height of the headrest body 20, preventing the headrest body 20 from moving in the height direction without the user's intention, ensuring the stability and reliability of the height of the headrest body 20, and improving the user experience.

[0050] In combination Figures 3-6 As shown, one of the first limiting portion 222 and the second limiting portion 311 is a limiting ball, and the other is a first limiting groove, and the limiting ball is selectively limited and matched with one of the plurality of first limiting grooves in the up-down direction.

[0051] Specifically, one of the first limiting portion 222 and the second limiting portion 311 can be arranged as a limiting ball, and the other can be arranged as a first limiting groove, so that when the lifting adjustment assembly 30 slides in the first sliding groove 221, the limiting ball can roll and selectively fall into one of the first limiting grooves and be limited and matched with the first limiting groove. Not only can it reduce the resistance of the limiting cooperation between the first limiting portion 222 and the second limiting portion 311 to the sliding cooperation between the lifting adjustment assembly 30 and the first sliding groove 221, but also can make the limiting cooperation of the first limiting portion 222 and the second limiting portion 311 more simple and reliable, and can improve the stability and reliability of the position of the headrest 100.

[0052] In combination Figures 3-6As shown, the headrest body 20 can mainly include: a headrest cotton 21 and a first cover plate 22 connected to the rear of the headrest cotton 21, and the first cover plate 22 is provided with a first sliding groove 221. In this way, the headrest cotton 21 can adapt to the shape of the user's head, softly support the user's head, and improve the user's comfort. By connecting the first cover plate 22 to the rear of the headrest cotton 21, the first cover plate 22 is a hard structure, and only the first sliding groove 221 needs to be provided on the first cover plate 22, and the lifting adjustment assembly 30 is connected in the first sliding groove 221, which can ensure the slidable connection between the lifting adjustment assembly 30 and the first sliding groove 221, and can ensure the structural reliability.

[0053] Further, the lifting adjustment assembly 30 can mainly include: a second cover plate 31 and a third cover plate 32, the second cover plate 31 is arranged in the first sliding groove 221, and the third cover plate 32 is arranged on the rear side of the first cover plate 22 and at least partially penetrates the first sliding groove 221 to connect the second cover plate 31, and the rear side of the third cover plate 32 is provided with a first mounting hole 321.

[0054] In this way, the connection between the headrest body 20 and the lifting adjustment assembly 30 can be realized, the second cover plate 31 is limited in the first sliding groove 221, so that the limiting cooperation between the first limiting portion 222 and the second limiting portion 311 can be ensured, and the second cover plate 31 can be prevented from falling out of the first sliding groove 221, and the sliding cooperation between the lifting adjustment assembly 30 and the headrest body 20 can be avoided. Failure, thereby the structural reliability of the headrest 100 of the seat can be ensured.

[0055] In combination Figures 3-6 As shown, the first limiting portion 222 is a first limiting groove, the second limiting portion 311 is a limiting ball, the second cover plate 31 is provided with a second mounting groove 312 on the side facing the first limiting groove, the limiting ball is arranged in the second mounting groove 312, and the first elastic member is arranged between the limiting ball and the second mounting groove 312. The first elastic member selectively drives the limiting ball and one of the plurality of first limiting grooves to limit cooperation in the up-down direction.

[0056] Specifically, the first limiting portion 222 is arranged as a first limiting groove, and the second limiting portion 311 is arranged as a limiting ball. It can be understood that the first limiting groove is a plurality of limiting grooves, and the limiting ball can be at least one. In this way, the structural design of the first limiting portion 222 and the second limiting portion 311 can be optimized, the processing and manufacturing of the first limiting portion 222 and the second limiting portion 311 are facilitated, the structure of the headrest 100 is simpler, and the production cost is reduced.

[0057] Further, the second cover plate 31 is provided with a second installation slot 312 on the side facing the first limiting slot, a limiting ball is arranged in the second installation slot 312, and a first elastic member is arranged between the limiting ball and the second installation slot 312, so that the limiting ball can be selectively limited and matched with one of the plurality of first limiting slots in the up-down direction under the joint action of the first elastic member and the first sliding slot 221.

[0058] Specifically, the first elastic member is arranged between the limiting ball and the second installation slot 312, and the first elastic member can make the limiting ball at least partially protrude from the surface of the second cover plate 31.

[0059] When adjusting the height of the headrest body 20, the second cover plate 31 slides in the first sliding slot 221, the first sliding slot 221 selectively abuts against the limiting ball, the first elastic member can be deformed under pressure, allowing the limiting ball to move away from the first limiting slot, thereby reducing the resistance to the sliding fit between the second cover plate 31 and the first sliding slot 221, and making the adjustment of the height of the headrest body 20 more smooth.

[0060] When the headrest body 20 is adjusted to the required height, the first elastic member drives the limiting ball to approach the first limiting slot, so that the limiting ball can be limited and matched with one of the plurality of first limiting slots in the up-down direction, thereby improving the stability and reliability of the limiting and matching of the limiting ball and the first limiting slot.

[0061] In some embodiments of the present application, as shown in Figure 3 and Figure 5 , the left and right sides of the first sliding slot 221 are each provided with a plurality of first limiting portions 222, and the left and right sides of the second cover plate 31 are each provided with a second limiting portion 311, so that the headrest body 20 and the second cover plate 31 can form a limiting fit on both sides in the left-right direction, thereby making the force on the headrest body 20 and the second cover plate 31 more uniform, and making the fixation of the headrest 100 more stable and reliable.

[0062] As shown in Figure 3 and Figure 4 , the sleeve member 40 can include an outer sleeve 42 and an inner sleeve 41, the rear end of the outer sleeve 42 is connected with the headrest fixing plate 10, the front end of the inner sleeve 41 is provided with a second installation hole 411, and the inner sleeve 41 is movably arranged in the outer sleeve 42. In this way, only the inner sleeve 41 needs to be moved in the front-rear direction relative to the outer sleeve 42 to achieve the adjustment of the headrest body 20 in the front-rear direction, thereby adapting to the use demand of different users for the position of the headrest body 20 in the front-rear direction.

[0063] In addition, the sleeve fitting 40 may also include a decorative cover 43, which engages with the front end of the outer sleeve 42. In this way, the decorative cover 43 can cover and decorate the front end of the outer sleeve 42, thereby further enhancing the exquisite feel of the sleeve fitting 40 and even the headrest 100, and improving the user experience.

[0064] Combination Figure 3 and Figure 4 As shown, the inner sleeve 41 is provided with a second sliding groove 412, which extends in the front-rear direction and is provided with a plurality of third limiting parts 413. The plurality of third limiting parts 413 are spaced apart in the front-rear direction. The outer sleeve 42 is provided with a fourth limiting part 421, which selectively engages with one of the plurality of third limiting parts 413.

[0065] Specifically, by providing a second sliding groove 412 in the inner sleeve 41, extending the second sliding groove 412 in the front-back direction, and providing a fourth limiting part 421 in the outer sleeve 42, the user can apply force to the headrest body 20, causing the fourth limiting part 421 and the second sliding groove 412 to slide relative to each other in the front-back direction. This limits the sliding path of the inner sleeve 41 and allows the inner sleeve 41 and the outer sleeve 42 to slide relative to each other in the front-back direction, thereby enabling the adjustment of the front-back position of the headrest body 20. This facilitates the user's adjustment of the front-back position of the headrest body 20.

[0066] Furthermore, by providing multiple third limiting parts 413 within the second slide groove 412, with the multiple third limiting parts 413 spaced apart in the front-back direction, and providing a fourth limiting part 421 on the outer sleeve 42, after the user adjusts the headrest body 20 to the desired position in the front-back direction, the third limiting parts 413 and the fourth limiting parts 421 can engage in a limiting action in the front-back direction, thereby fixing the position of the headrest body 20 in the front-back direction. This prevents the headrest body 20 from moving unintentionally under the user's resistance, ensuring the stability and reliability of the headrest body 20's position in the front-back direction, and improving the user experience.

[0067] Combination Figure 3 and Figure 4 As shown, the third limiting part 413 is the second limiting groove, and the fourth limiting part 421 is the limiting block. In the left-right direction, a second elastic member is also connected between the limiting block and the outer sleeve 42. The second elastic member selectively drives the fourth limiting part 421 to engage with one of the multiple third limiting parts 413 in the front-back direction.

[0068] Specifically, the third limiting part 413 is arranged as a second limiting groove, and the fourth limiting part 421 is arranged as a limiting block. It can be understood that the second limiting groove is multiple, and the limiting block can be at least one. In this way, the structural design of the third limiting part 413 and the fourth limiting part 421 can be optimized, the processing and manufacturing of the third limiting part 413 and the fourth limiting part 421 are facilitated, the structure of the headrest 100 is simpler, and the production cost is reduced.

[0069] Further, the second elastic member is connected between the limiting block and the outer sleeve 42 in the left-right direction. In this way, the limiting block can selectively limit and cooperate with one of the multiple second limiting grooves in the front-rear direction under the joint action of the outer sleeve 42 and the second elastic member.

[0070] Specifically, the second elastic member is arranged between the limiting block and the outer sleeve 42. The second elastic member will apply a force to the limiting block to approach the second limiting groove, so that the limiting block abuts against the outer sleeve 42 in the left-right direction toward one side of the second limiting groove.

[0071] When adjusting the position of the headrest body 20 in the front-rear direction, the second limiting groove relatively slides in the second sliding groove 412. The second sliding groove 412 will selectively abut against the limiting block. The second elastic member can be deformed under pressure, allowing the limiting block to move away from the second limiting groove. Thus, the resistance to the sliding cooperation between the second limiting groove and the second sliding groove 412 can be reduced, and the adjustment of the position of the headrest body 20 in the front-rear direction can be smoother.

[0072] When the headrest body 20 is adjusted to the required position in the front-rear direction, the second elastic member drives the limiting block to approach the second limiting groove, so that the limiting block can limit and cooperate with one of the multiple second limiting grooves in the front-rear direction. The stability and reliability of the limiting cooperation between the second limiting groove and the limiting block can be ensured, thereby effectively preventing the headrest body 20 from moving unintentionally under the user's leaning, ensuring the stability and reliability of the position of the headrest body 20 in the front-rear direction, and improving the user's experience.

[0073] Optionally, the second limiting groove is in a stepped shape. In this way, the smoothness and convenience of the front-rear adjustment can be further ensured, and the stability and reliability of the position of the headrest body 20 in the front-rear direction can be further ensured.

[0074] Further, in combination with the Figure 3 and Figure 4 shown, a third mounting hole 422 can be arranged at the bottom of the outer sleeve 42. The limiting block and the second elastic member can be arranged in the third mounting hole 422, and then another pressing plate 423 is additionally arranged.
