[0047] Overall, the seat headrest mounting structure includes a headrest main body 3, a backrest framework 20, and a headrest framework 4 fixed to the backrest framework 20. Wherein, the backrest framework 20 is wrapped with a backrest covering body 21, and the headrest framework 4 has a main body part that penetrates out to the outside of the backrest covering body 21; the headrest main body 3 is fixed on the main body part, and the main body part is wrapped inside the headrest main body 3.

[0048] It should be pointed out that based on the overall design idea, the technical scheme of the utility model can adopt various different specific implementation structures, forms or configuration sequences. For example, the setting of the headrest framework 4 on the backrest framework 20 can adopt welding, screwing and the like. The backrest covering body 21 and the headrest covering body 31 of the headrest main body 3 can adopt various materials such as fabric, leather, sponge and rubber pad to wrap and pad the framework structure in multiple layers. The assembly mode of the headrest main body 3 on the headrest framework 4 can also be flexibly adjusted. For the parts required by the overall scheme implementation but not involved in the overall setting, reasonable and flexible design can be made by referring to the mature setting means in the field, the actual situation during implementation and the like. The specific implementation scheme described in the embodiment is only one of the relatively optimal schemes formed by various combinations and changes of the above, and in actual implementation, the person skilled in the art can make flexible adjustment and improvement in combination with the actual situation. Obviously, the various specific form combinations and changes of the above can form various schemes, and the specific implementation scheme of the embodiment is within the protection scope of the utility model.

[0049] In addition, it should be pointed out that the seat headrest mounting structure of the utility model can be applied to the headrests of various seats, and is especially suitable for the mounting and setting of the headrests of the seats of vehicles. The seat of a vehicle is taken as an example for description in the embodiment. Figure 1 A seat of a vehicle is shown, which comprises a seat cushion part 1, a seat backrest 2 and a headrest arranged on the top of the seat backrest 2. The seat backrest 2 comprises a backrest framework 20 and a backrest covering body 21 wrapped outside the backrest framework 20. The backrest covering body 21 can adopt fabric or leather as an outer layer, and sponge, foam or colloid as a padding layer between the outer layer and the framework. The headrest comprises a headrest main body 3 and a headrest framework 4 for fixing the headrest main body 3. The headrest covering body 31 of the headrest main body 3 can be arranged in the same way as the backrest covering body 21, that is, fabric or leather is adopted as an outer layer, and sponge, foam or colloid is adopted as a padding layer.

[0050] For the relative setting position of the headrest main body 3 on the top of the seat backrest 2, various different structural schemes can be selected. For example, the headrest main body 3 can be arranged directly above the seat backrest 2, or the headrest main body 3 can be arranged on the top of the seat backrest 2 and slightly offset to the front side. In the embodiment, as shown in Figure 3 , Figure 4 After the headrest framework 4 is arranged on the top of the seat backrest 2, the main body part of the headrest framework 4 is located on the front side of the backrest top 210, and the top of the main body part is higher than the backrest top 210. At the same time, the rear lower part of the headrest main body 3 is connected to the backrest top 210 in abutment.

[0051] The back top 210 of the back cover 21 is higher than the bottom of the headrest body 3, thereby supporting the headrest body 3 at the rear side of the headrest body 3, and further improving the stability of the headrest body 3. Preferably, the highest point of the back top 210 of the back cover 21 is arranged at the middle position of the rear side of the headrest body 3, and the entire middle and lower part of the headrest body 3 is supported by the back cover 21 in the front-rear direction of the vehicle. In this way, when the vehicle is rapidly accelerated or the vehicle is rear-ended, the headrest body 3 can stably and reliably protect the head and neck of the driver or passenger.

[0052] The specific form of the headrest framework 4 can be variously selected. In the embodiment, as shown in Figure 5 、 Figure 6 the headrest framework 4 comprises a main frame 40, the main frame 40 has a root 400 connected to the top front side of the back framework 20, a penetrating segment 401 extending from the root 400 to the front upper side of the seat to penetrate the back cover 21, and a body frame 402 connected to the top of the penetrating segment 401, and the body part is arranged on the body frame 402. The headrest framework 4 adopts a frame structure, and has the root 400, the penetrating segment 401 and the body frame 402 connected together; each part can respectively play the functions of connection, penetration and formation of the body part, so that the body part can be arranged at the appropriate position of the top front side of the seat back 2, and a reasonable mounting position and stable mounting foundation are provided for the installation and fixation of the headrest body 3.

[0053] The main frame 40 described above can be a cast part, or a profile steel bent and extruded. In the embodiment, the main frame 40 is bent from a pipe profile, and the whole is in the shape of “U”; as shown in Figure 6 the two ends of the main frame 40 form two roots 400 respectively, the body frame 402 is located at the middle of the main frame 40, and the penetrating segment 401 is two segments connected between the two roots 400 and the body frame 402 respectively.

[0054] The headrest framework 4 is arranged in the inverted U shape, and is bent and processed from the pipe profile, which not only facilitates the raw material, but also simplifies the processing technology, and the structural performance of the framework is also relatively reliable. The body frame 402 located at the middle is in the shape of a semicircle, which can be directly used as the body part for mounting the headrest body 3, and further provides good conditions and stable foundation for the assembly and fixation of the bottom plate 41 described below.

[0055] Based on the above setting, the main body part of the headrest framework 4 of the present embodiment includes a bottom plate 41 arranged on the main body frame 402, which is of course a part of the main body part. The bottom plate 41 is preferably arranged facing the front of the vehicle, and the headrest main body 3 is fixed to the bottom plate 41. The bottom plate 41 is arranged in the main body part, and the bottom plate 41 is arranged facing the front of the vehicle, which can provide sufficient support area in the front-rear direction of the vehicle; in this way, the bottom plate 41 provides good conditions for the fixation of the headrest main body 3, and can effectively form stable support for the headrest main body 3.

[0056] In addition, as shown in Figure 6 The main body part of the present embodiment also includes an upper support frame 42 arranged on the back of the bottom plate 41, and the main body frame 402 and the upper support frame 42 are arranged in a front-rear direction, and the upper support frame 42 supports the top of the headrest main body 3. The upper support frame 42 is arranged on the back of the bottom plate 41, and the upper support frame 42 and the main body frame 402 are arranged in a front-rear direction; in this way, the upper support frame 42 and the main body frame 402 can form a certain support width in the front-rear direction of the vehicle, and both are located at the top of the headrest main body 3, so they can well support the top profile of the headrest main body 3 and provide good support for the top of the headrest main body 3.

[0057] In addition, a rear support frame 45 can also be arranged on the back of the bottom plate 41. Specifically, the rear support frame 45 of the present embodiment extends from the bottom of the bottom plate 41 to above the backrest framework 20, and the rear support frame 45 can be designed as an upwardly bent structure; the rear support frame 45 penetrates into the inside of the backrest cover 21 and is supported in the backrest top 210, which can further improve the connection stability between the headrest main body 3 and the seat backrest 2, and is beneficial to improve the structural support ability of the backrest top 210.

[0058] Based on the arrangement of the bottom plate 41, some auxiliary support structures can also be selectively arranged on the bottom plate 41. Specifically, the main body part of the headrest framework 4 of the present embodiment also includes an upper bracket 44 arranged on the top of the bottom plate 41, and a lower bracket 43 arranged on the bottom of the bottom plate 41. The upper bracket 44 is inserted and fitted with the headrest main body 3 to support the top of the headrest main body 3; the lower bracket 43 is inserted and fitted with the headrest main body 3 to support the bottom of the headrest main body 3. The arrangement of the upper bracket 44, the lower bracket 43 and other auxiliary support structures on the bottom plate 41 can provide good positioning and support for the top, bottom and other parts of the headrest main body 3, and can also provide good auxiliary positioning and support during the installation of the headrest main body 3, facilitating the installation and fixation of the headrest main body 3 on the bottom plate 41.

[0059] Of course, there are many different structural schemes for the structure of the headrest main body 3. In the present embodiment, as shown in Figure 6 andFigure 7 、 Figure 8 As shown in FIG. 1, the headrest body 3 comprises a base plate 30 fixed on the body part, a headrest cover 31 wrapped around the front side and the periphery of the base plate 30, and a back cover plate 32 buckled on the upper part of the back side of the base plate 30. The back cover plate 32 is arranged to form a closed structure on the back side of the headrest body 3, so as to cover the body part exposed on the back side of the base plate 30, thereby forming a complete wrapping of the headrest body 3 on the body part.

[0060] The base plate 30 of the headrest body 3 forms a skeleton support structure of the headrest body 3 itself, and provides a skeleton basis for the wrapping of the headrest cover 31. When the headrest body 3 is installed, the base plate 30 can be fixed on the bottom plate 41. In this embodiment, the base plate 30 is provided with a threaded hole 300, and the bottom plate 41 is provided with a through hole 410. The installation bolt 5 is used to pass through the through hole 410 from the back of the bottom plate 41 and is screwed into the threaded hole 300, thereby achieving reliable connection between the bottom plate 41 and the base plate 30. The upper bracket 44 and the lower bracket 43 can also be inserted and matched with the base plate 30. Specifically, the base plate 30 is provided with a bracket assembly hole 306 corresponding to the lower bracket 43, and the lower bracket 43 can be inserted into the bracket assembly hole 306 to position and support the entire headrest body 3. The upper bracket 44 is positioned and matched with the bracket support structure provided on the base plate 30. In addition, for the tubular structure of the main frame 40, a frame positioning groove 307 can be arranged on the base plate 30 to be positioned and matched with part of the body frame 402, thereby improving the structural stability between the base plate 30 and the main frame 40.

[0061] In view of the fact that the backrest top part 210 of the backrest cover 21 is attached to the lower part of the back side of the headrest body 3, the back cover plate 32 can be buckled on the upper part of the back side of the entire headrest body 3, and the bottom part of the back cover plate 32 is connected to the backrest top part 210 of the backrest cover 21, thereby forming a close fit between the headrest body 3 and the seat backrest 2 at each angle position, making the appearance of the top part of the seat neat and beautiful, and the headrest body 3 is more stable and close on the seat backrest 2.

[0062] For the assembly mode of the headrest skeleton 4 and the headrest body 3, there are of course many different structure schemes to choose from. In this embodiment, as shown in FIG. 1 and FIG. 2, the back cover plate 32 is connected to the base plate 30 by clamping. Figure 7 and Figure 8 The clamping structure is adopted to install and fix the back cover plate 32 and the base plate 30, which facilitates the smooth operation of the installation and makes the installation more convenient and simple.

[0063] In the specific implementation, two first clamping holes 301 and positioning holes 302 can be symmetrically arranged on the top of the substrate 30. Corresponding to the first clamping holes 301, two first clamping heads 321 are arranged on the top of the back cover plate 32. Corresponding to the positioning holes 302, two positioning columns 322 are arranged on the back cover plate 32. The first clamping heads 321 are clamped into the corresponding first clamping holes 301, and the positioning columns 322 are inserted into the corresponding positioning holes 302 to play a positioning role.

[0064] Meanwhile, the two sides of the top of the substrate 30 of the embodiment are each provided with a second clamping hole 303, and corresponding second clamping heads 323 are arranged on the back cover plate 32. The positioning holes 302 are clamped and matched with the corresponding second clamping heads 323. The bottom of the substrate 30 is also provided with a third clamping hole 304 and a fourth clamping hole 305 on both sides, and corresponding third clamping heads 324 and fourth clamping heads 325 are arranged on the back cover plate 32. The third clamping hole 304 is clamped and matched with the corresponding third clamping head 324, and the fourth clamping hole 305 is clamped and matched with the corresponding fourth clamping head 325. Through the arrangement of the clamping structures at the above positions, the headrest framework 4 can be firmly clamped and fixed to the substrate 30, and the top and the edges on both sides of the back cover plate 32 are connected with the edge parts of the headrest cover 31. The bottom of the back cover plate 32 is in abutment with the backrest top 210 of the backrest cover 21; this makes the overall structure of the headrest body 3 compact, the external appearance is neat and beautiful, and the connection between the headrest and the seat backrest 2 is also compact and reliable.

[0065] In summary, the seat headrest mounting structure of the embodiment directly connects the headrest framework 4 to the backrest framework 20 to form an integrated framework structure. The headrest framework 4 penetrates the backrest cover 21 located outside the backrest framework 20 to form a main body part for bearing the headrest body 3 outside the seat backrest 2, and the headrest body 3 is fixed to the main body part, effectively improving the connection reliability between the headrest body 3 and the seat backrest 2. Meanwhile, the headrest body 3 also forms a good wrapping for the main body part, and the framework structure is well hidden and covered, thereby providing a seat headrest mounting structure with good stability and reliability.

[0066] Embodiment Two

[0067] The embodiment relates to a vehicle, at least part of the seat of the vehicle adopts the seat headrest mounting structure provided in the embodiment one.

[0068] In the prior art, the headrest and the seat backrest are usually connected in a detachable structure, but such a detachable structure has the following problems:

[0069] 1. The headrest is an important safety part. If the headrest is not installed on the seat in time after being detached, the neck of the driver or passenger lacks the protection and support of the headrest in an accident, and the risk of cervical spine injury is greatly increased;

[0070] 2. If the locking mechanism fails or the locking mechanism is separated from the backrest frame, the detachable headrest may be separated from the seat backrest in a collision accident, and the head and neck of the driver and passenger may lose protection, thereby greatly increasing the risk of head and neck injury;

[0071] 3. The detachable headrest may be stolen or lost due to random placement after being detached. For example, for an operating vehicle, the rear passenger may steal the headrest of the seat when the driver is not paying attention;

[0072] 4. The detachable headrest and the seat backrest are connected by a telescopic rod, and there is a gap between the detachable headrest and the seat backrest. During the extension and retraction of the telescopic rod to adjust the height of the headrest, the hair of the driver and passenger may be clamped.

[0073] The seat headrest mounting structure of the utility model is developed and improved for the above problems.
