Technical Field

[0001] The utility model belongs to the technical field of chairs and relates to a pillow connecting structure of a chair. Background Art

[0002] The pillow of an existing chair is usually fixed to the upper end of the chair back, and serves as a place for the user's head to rest, so that the user can lie down and sleep. However, since the chair is used for people of different heights, the placement of the pillow also needs to be adjusted to improve the versatility of the chair headrest.

[0003] Therefore, the existing Chinese patent application [Authorization Announcement No.: CN218791380U] discloses a seat with a magnetic pillow, including a seat back, a seat plate, a headrest, a first mounting plate and a second mounting plate, and the upper part of the seat back is respectively provided with two horizontally arranged first clamping holes and two vertically arranged second clamping holes, one side of the first mounting plate is provided with two first clamping blocks, the two first clamping blocks are used to insert the two first clamping holes or the two second clamping holes, a side of the first mounting plate away from the first clamping blocks is provided with several groups of third clamping holes along its length direction, one side of the second mounting plate is provided with two second clamping blocks, the two second clamping blocks are used to insert a group of third clamping holes, an iron sheet is provided inside the third clamping hole, a magnet is provided at the end of the second clamping block, and the second mounting plate is fixedly connected to the headrest.

[0004] The above structure is provided with several groups of third clamping holes. A magnet is provided at the end of the second clamping block, an iron sheet is provided inside the third clamping hole, and the second clamping block is inserted into the corresponding third clamping hole. The position of the headrest is adjusted by the attraction of the magnet and the iron sheet. However, since the above structure requires multiple groups of clamping holes to be opened on the seat back and an iron sheet is additionally provided to achieve connection, only multi-level adjustment can be achieved during the adjustment process. For users of different heights, the adjustment range of the multi-level adjustment is limited. Since it is necessary to open holes on the seat back, the production difficulty is increased. Utility Model Content

[0005] The purpose of the utility model is to address the above-mentioned problems in the existing technology and to propose a pillow connection structure for a chair. The technical problem to be solved by the utility model is: how to solve the problem that the existing pillow connection structure has high production difficulty and limited adjustment stroke.

[0006] The purpose of the utility model can be achieved through the following technical solutions:

[0007] A pillow connection structure for a chair, the chair comprising a chair back and a pillow, the left and right sides of the chair back having support longitudinal beams arranged along the length direction of the chair back, characterized in that the support longitudinal beams are made of iron material, the pillow connection structure comprises connection ears respectively arranged on the left and right sides of the pillow, the connection ears are each provided with a magnet, and the connection ears can be bent backwards and attracted to the corresponding support longitudinal beams.

[0008] When the position of the pillow needs to be adjusted, the connecting ear can be separated from the supporting longitudinal beam, and after the pillow is adjusted to the corresponding position, the connecting ear can be bent backward so that the magnet on the connecting ear is attracted to the corresponding supporting longitudinal beam. Since the pillow needs to slide on the chair back, the connection between the pillow and the chair back can be achieved only by the connecting ears arranged on the left and right sides of the pillow. In actual use, when lying down to sleep, the pillow can be arranged at the upper end of the chair back as a headrest, and when sitting normally, the pillow can be arranged at the lower end or the middle of the chair back and used as a lumbar support, thereby improving the practicality of the pillow. In order to facilitate adjustment, connecting ears are respectively arranged on the left and right sides of the pillow, so that The connecting ears on the left and right sides of the pillow can be positioned independently. The connecting ears only need to be bent backwards to achieve the attraction between the connecting ears and the supporting longitudinal beam, so as to realize stepless adjustment of the pillow position. The connecting ears on the left and right sides of the pillow do not affect each other. When in use, only each connecting ear needs to be adjusted separately, which improves the convenience of adjustment and makes the adjustment range of the pillow larger. Since the supporting longitudinal beam is the chair back structure of the chair itself, only connecting ears are added to the headrest and magnets are arranged on the connecting ears. In addition, by utilizing the existing supporting longitudinal beam of the chair back, only the pillow is improved, thereby reducing the production difficulty of the pillow connection structure.

[0009] In the pillow connection structure of the above-mentioned chair, the connection ear is made of flexible material, and the connection ear has a bending portion connected to the pillow and a magnetic attraction portion connected to the bending portion, and a receiving space for placing a magnet is opened in the magnetic attraction portion.

[0010] The connecting ear can be made of flexible materials such as leather or cloth, so that the connecting ear is relatively soft and can be bent backward. At this time, the connecting ear has a bending portion and a magnetic portion. The magnetic portion is provided with a storage space for placing the magnet. Since the magnet is a hard material, the setting of the bending portion ensures that the setting of the magnet will not affect the bending of the connecting ear. Therefore, a relatively simple structure can be used to realize the setting of the connecting ear and the magnet, reducing the difficulty of adjusting the pillow connection structure.

[0011] In the pillow connection structure of the above-mentioned chair, the connection ear is connected to a side of the pillow close to the chair back.

[0012] The setting of this structure makes it easier for the connecting ear to be connected. The connecting ear can press the side of the pillow close to the chair back against the chair back, which improves the connection stability between the pillow and the chair back, makes the fixing of the connecting ear simpler, and improves the convenience of disassembly and connection of the connecting ear.

[0013] In the pillow connection structure of the chair described above, a pair of connection ears are provided, and the connection ears are connected to the upper end of the side of the pillow or to the middle part of the side of the pillow.

[0014] Only one pair of connecting ears is required, and the connecting ears are connected to the upper end of the pillow side, so that the upper end of the pillow can be sucked together so that the upper edge of the pillow fits against the chair back, and the lower part of the pillow can fit against the chair back by relying on the weight of the pillow itself. Therefore, only one pair of connecting ears is required on the pillow, and the connecting ears are set on the upper edge of the pillow; or the connecting ears are connected to the middle part of the pillow side, so that the tension of the connecting ears acts on the middle part of the pillow side, and the tension on the pillow is more uniform, so that the pillow can rely on the tension in the middle part and its own gravity to stably fit on the chair back, so that the connecting ears are connected to the upper end or the middle part of the pillow side, both of which can achieve stability and convenience of connection.

[0015] In the pillow connection structure of the above-mentioned chair, the upper end of the chair back is slidably connected to a pillow extension frame, and the left and right sides of the pillow extension frame have sliding rods made of iron material. The pillow extension frame can partially extend out of the chair back and can be used to place a pillow, and the connecting ear can be bent backward and engaged with the sliding rod.

[0016] By setting the pillow extension frame, when lying down to sleep on the chair, the pillow extension frame can be pulled out, and then the pillow can be placed on the pillow extension frame and positioned by bending the connecting ears backwards and engaging with the sliding rod, thereby realizing the extension of the headrest part of the chair when lying down to sleep, and the positioning between the pillow extension frame and the pillow can also be achieved by relying on the magnet of the connecting ears and the attraction of the sliding rod, making the connection between the pillow extension frame and the pillow more convenient.

[0017] In the pillow connection structure of the chair described above, the slide bar is slidably connected to the supporting longitudinal beam, and a limiting step for the pillow to lean against is formed between the slide bar and the supporting longitudinal beam.

[0018] The setting of the limiting step enables the limiting step to limit the movement of the pillow along the length direction of the chair back when the pillow is placed on the pillow extension frame, thereby further making the setting of the pillow more stable.

[0019] In the pillow connection structure of the chair described above, the outer side wall of the supporting longitudinal beam has a fitting plane, and the end surface of the magnetic attraction portion can fit with the fitting plane.

[0020] By setting the fitting plane, the contact surface between the magnet and the supporting longitudinal beam is relatively stable and the contact area is larger, thereby improving the stability of the pillow connection.

[0021] In the pillow connection structure of the chair described above, the side edges of the pillow are close to the corresponding supporting longitudinal beams.

[0022] The size setting of the pillow can make the connecting ears more stably connect the pillow and the supporting beam, further improving the stability of the connection between the pillow and the chair back after adjustment.

[0023] Compared with the prior art, the pillow connection structure of the chair has the following advantages:

[0024] 1. For the convenience of adjustment, connecting ears are respectively provided on the left and right sides of the pillow, so that the connecting ears on the left and right sides of the pillow can be positioned independently. The connecting ears only need to be bent backwards to realize the suction of the connecting ears and the supporting longitudinal beams, so as to realize stepless adjustment of the pillow position. The connecting ears on the left and right sides of the pillow do not affect each other. When in use, you only need to adjust each connecting ear separately, which improves the convenience of adjustment and makes the adjustment range of the pillow larger.

[0025] 2. The connecting ear can be made of flexible materials such as leather or cloth, so that the connecting ear is relatively soft and can be bent backward. At this time, the connecting ear has a bending portion and a magnetic portion. The magnetic portion is provided with a storage space for placing the magnet. Since the magnet is a hard material, the setting of the bending portion does not affect the bending of the connecting ear. Therefore, a relatively simple structure can be used to realize the setting of the connecting ear and the magnet, reducing the difficulty of adjusting the pillow connection structure.

DETAILED DESCRIPTION

[0033] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0034] like Figure 1 As shown, the pillow connection structure of the chair comprises a chair backrest 1 and a pillow 2, and the left and right sides of the chair backrest 1 are provided with supporting longitudinal beams 11 arranged along the length direction of the chair backrest.

[0035] Specifically, Figure 1-6 As shown, the supporting longitudinal beam 11 is made of iron material. The pillow connection structure includes connecting ears 21 respectively arranged on the left and right sides of the pillow 2. The connecting ears 21 are provided with magnets 3. The connecting ears 21 are connected to the corresponding side edges of the pillow 2 and the connecting ears 21 can be bent backwards and engaged with the corresponding supporting longitudinal beam 11. The side edges of the pillow 2 are close to the corresponding supporting longitudinal beam 11. The outer side wall of the supporting longitudinal beam 11 has a fitting plane 11a, and the end face of the magnetic attraction portion 21b can fit with the fitting plane 11a.

[0036] When the position of the pillow 2 needs to be adjusted, the connecting ear 21 can be separated from the supporting longitudinal beam 11, and after the pillow 2 is adjusted to the corresponding position, the connecting ear 21 is bent backward, and the magnet 3 on the connecting ear 21 is attracted to the corresponding supporting longitudinal beam 11. Since the pillow 2 needs to slide on the chair back 1, the connection between the pillow 2 and the chair back 1 can be achieved only by the connecting ears 21 arranged on the left and right sides of the pillow 2. In actual use, when it is necessary to lie down and sleep, the pillow 2 can be arranged at the upper end of the chair back 1 as a headrest, and when sitting normally, the pillow 2 can be arranged at the lower end or the middle part of the chair back 1 and used as a lumbar support, which improves the practicality of the pillow 2. In order to facilitate adjustment, connecting ears 21 are respectively arranged on the left and right sides of the pillow 2, so that The connecting ears 21 located on the left and right sides of the pillow 2 can be positioned independently. The connecting ears 21 only need to be bent backwards to achieve the attraction between the connecting ears 21 and the supporting longitudinal beam 11, so as to achieve stepless adjustment of the position of the pillow 2. The connecting ears 21 located on the left and right sides of the pillow 2 do not affect each other. When in use, only each connecting ear 21 needs to be adjusted separately, which improves the convenience of adjustment and makes the adjustment range of the pillow 2 larger. Since the supporting longitudinal beam 11 is the chair back 1 structure of the chair itself, only the connecting ears 21 are added to the headrest, and the magnets 3 are arranged on the connecting ears 21. By utilizing the existing supporting longitudinal beam 11 of the chair back 1, only the pillow 2 is improved, which reduces the production difficulty of the pillow connection structure.

[0037] In actual use, the number of connecting ears 21 can be actually set according to the size of the pillow 2. Since the connecting ears 21 are all connected by adsorption using the magnets 3, the connection and disassembly of the multiple connecting ears 21 are also relatively convenient.

[0038] like Figure 1-4 As shown, the connecting ear 21 is made of a flexible material, and the connecting ear 21 has a bending portion 21a connected to the pillow 2 and a magnetic attraction portion 21b connected to the bending portion 21a, and a receiving space 21b1 for placing the magnet 3 is provided in the magnetic attraction portion 21b, and the connecting ear 21 is connected to the side of the pillow 2 close to the chair back 1, and a pair of connecting ears 21 are connected to the upper end of the side of the pillow 2 or to the middle of the side of the pillow 2.

[0039] In actual settings, the connecting ear 21 can also be made of materials such as rubber, and the magnet 3 can be directly bonded to the connecting ear 21, or an open groove can be opened on the connecting ear 21, and the magnet 3 can be embedded in the open groove.

[0040] like Figure 4 and Figure 5As shown, the upper end of the chair back 1 is slidably connected to a pillow extension frame 4, and the left and right sides of the pillow extension frame 4 have sliding rods 41 made of iron material. The pillow extension frame 4 can partially extend out of the chair back 1 and can be used to place the pillow 2. The connecting ear 21 can be bent backward and engaged with the sliding rod 41. The sliding rod 41 is slidably connected to the supporting longitudinal beam 11, and a limiting step 5 for the pillow 2 to lean against is formed between the sliding rod 41 and the supporting longitudinal beam 11.

[0041] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
