Description

Technical Field

[0001] This utility model relates to the field of seating technology, specifically to a seat with a sliding headrest. Background Technology

[0002] Chairs are a popular choice for office seating. The back of a chair typically consists of a back frame and a mesh fabric covering the front of the back frame. The breathability of the mesh fabric not only prevents office workers from feeling stuffy and sweaty when sitting for long periods of time, but its elasticity also provides a soft and resilient support experience, resulting in good comfort.

[0003] To support the user's head, a headrest is also installed on the upper side of the back frame. For example, an existing patent provides a headrest and seat (application number: CN201721142509.5), which includes a headrest frame, a connecting rod, and a back frame support frame. A connector is slidably connected to the back frame support frame. One end of the connecting rod is detachably connected to the headrest frame, and the other end is inserted into the connector, so that the headrest frame can be moved relative to the back frame support frame by the connector and the connecting rod. That is, the user can adjust the position of the headrest according to personal preference.

[0004] However, the backrest support frame of this type of seat is only covered with mesh fabric on the front side, which exposes the rear side of the backrest support frame and the connection structure between the headrest frame and the backrest support frame. This makes the seat look less integrated and simple, and less aesthetically pleasing.

[0005] To address the aforementioned problems, the inventors aim to provide a seat, as shown in the attached figure. Figure 1 and attached Figure 2 As shown, the back frame is completely covered by a fabric cover, preventing it from being exposed and thus maintaining a good overall look with a simple and elegant aesthetic. However, with the back frame covered by the fabric cover, it is not convenient to connect the headrest to the back frame through the fabric cover. How to slide the headrest to the back frame without affecting the seat's aesthetics has become the main problem that needs to be solved. Summary of the Invention

[0006] In view of the above-mentioned defects or deficiencies in the prior art, it is desirable to provide a seat with a sliding headrest. By cutting out a relief opening in the fabric cover to avoid the mounting part, the headrest body is connected to the mounting part through a sliding structure. This not only allows the headrest body to slide up and down relative to the back frame to adjust its height, which is more practical, but also hides the sliding structure between the headrest body and the fabric cover. The fabric cover wraps around the back frame and is relatively intact in appearance. Furthermore, the headrest body, the back frame, and the fabric cover are relatively compact, which makes the seat look more integrated and has a simple and elegant aesthetic.

[0007] The effect of this utility model is achieved as follows:

[0008] This application provides a seat with a sliding headrest, including a back frame and a headrest body. The back frame is a square frame structure, and includes a mounting part arranged horizontally at the top. A cloth cover is fitted on the back frame, and the cloth cover has front and back surfaces. The front surface of the cloth cover has a cutout at the part facing the mounting part, so that the mounting part is exposed through the cutout. The headrest body and the mounting part are connected by a sliding structure, so that the headrest body can slide up and down relative to the back frame, and the headrest body can be suspended at multiple vertical heights.

[0009] Furthermore, the sliding structure includes a mounting component and a sliding component. The mounting component has a recessed groove extending vertically, and the sliding component is slidably connected to the mounting component through the groove. The mounting component is connected to one of the headrest body and the mounting part, and the sliding component is connected to the other of the headrest body and the mounting part. This design satisfies the sliding adjustment of the headrest body while making the structure between the mounting component and the sliding component relatively compact and not easily exposed.

[0010] Furthermore, the mounting component is connected to the rear end of the headrest body, and a sliding groove is formed at the front end of the mounting component. The bottom of the sliding groove is hollowed out to form a connecting groove. The sliding component and the mounting part are detachably connected by screws, which pass through the sliding component and the connecting groove and are screwed into the mounting part. This not only provides high connection strength but also simplifies the assembly of the seat.

[0011] Furthermore, the sliding structure also includes a limiting member and several limiting grooves. The limiting member is located in one of the mounting member and the sliding member, and the limiting grooves are located in the other of the mounting member and the sliding member. When the sliding member slides up and down, the limiting member engages with the limiting grooves in sequence. This allows the sliding adjustment of the headrest body to have a tactile feel, and the headrest body can be suspended at multiple vertical heights.

[0012] Furthermore, the bottom of the groove is hollowed out to form a connecting groove. The sliding component includes a connecting part that engages with the connecting groove. Several limiting grooves are recessed on the groove wall of the connecting groove, and the limiting components are correspondingly connected to the side wall of the connecting part. The sliding component is engaged with the connecting groove through the connecting part, which not only further enhances the connection strength between the sliding component and the mounting component, but also makes the limiting grooves easier to process and allows for the creation of more limiting grooves for engagement.

[0013] Furthermore, a mounting hole is recessed on the side wall of the connecting part, through which the limiting member is engaged with the connecting part, and the limiting member can slide left and right along the mounting hole. This results in good connection stability between the limiting member and the connecting part, and the limiting member is not easily detached from the connecting part during adjustment.

[0014] Furthermore, an elastic element is provided inside the mounting hole, which pushes against the limiting element, ensuring that the limiting element always tends to engage with the limiting groove. The limiting element not only engages stably in the limiting groove with good stability, but also automatically disengages from the limiting groove and engages with the next limiting groove due to the deformation of the elastic element, thus making the sliding adjustment operation of the headrest body simpler.

[0015] Furthermore, the limiting component has elastic deformation capability, allowing it to move between several limiting grooves. This not only enhances the stability of the connection between the limiting component and the limiting grooves but also ensures smooth movement of the limiting component between the various limiting grooves, making the sliding adjustment operation of the headrest body more convenient.

[0016] Furthermore, the sliding component includes a sliding part and a connecting part that are spliced ​​together front and back. The sliding part is engaged with a sliding groove, and the front end of the connecting part also protrudes to form a connecting post. The limiting member is an elastic rubber washer, which is engaged with the connecting part through the connecting post and clamped between the connecting part and the sliding part. The limiting member not only has good elastic deformation capability, but also makes the sliding adjustment operation of the headrest body not only smooth, but also generates less noise; and, by setting the sliding component as a split structure and clamping the limiting member, the connection strength is high and the assembly is relatively convenient.

[0017] Furthermore, the side wall of the slider is provided with several hooks, which have elastic deformation capability, and the slider abuts against the groove wall of the slide groove through the hooks. This allows the slider to be stably engaged in the slide groove and enhances the damping feel when the slider is adjusted, thereby allowing the headrest body to be stably suspended at the current position, resulting in better stability.

[0018] The seat with a sliding headrest provided in this application avoids the mounting part by hollowing out a notch in the fabric cover. The headrest body is connected to the mounting part through a sliding structure. This not only allows the headrest body to slide up and down relative to the back frame to adjust its height, which is practical, but also hides the sliding structure between the headrest body and the fabric cover. It will not be exposed during the sliding of the headrest body. The fabric cover wraps around the back frame and is relatively intact in appearance. Furthermore, the headrest body, the back frame, and the fabric cover are relatively compact, which makes the seat look more integrated and has a simple and elegant aesthetic.

Detailed Implementation

[0029] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the relevant utility model and not intended to limit the scope of the utility model. Furthermore, it should be noted that, for ease of description, only the parts relevant to the utility model are shown in the accompanying drawings.

[0030] Please refer to the attached document. Figure 1-8 This application provides a seat with a sliding headrest, including a back frame 1 and a headrest body 2. The back frame 1 is a square frame structure, and includes a mounting part 110 arranged horizontally at the top. A cloth cover 5 is fitted on the back frame 1. The cloth cover 5 has front and back surfaces. The front surface of the cloth cover 5 is hollowed out with an avoidance opening 501 in front of the mounting part 110, so that the mounting part 110 is exposed through the avoidance opening 501. The headrest body 2 and the mounting part 110 are connected by a sliding structure, so that the headrest body 2 can slide up and down relative to the back frame 1, and the headrest body 2 can be suspended at multiple vertical heights.

[0031] In this embodiment, by hollowing out the clearance opening 501 on the fabric cover 5 to avoid the mounting part 110, the headrest body 2 is connected to the mounting part 110 through a sliding structure. This not only allows the headrest body 2 to slide up and down relative to the back frame 1 to adjust its height, improving its practicality, but also allows the clearance opening 501 to be formed on the fabric cover 5. The sliding structure is hidden between the headrest body 2 and the fabric cover 5, while the mounting part 110 is exposed through the clearance opening 501. It will not be exposed during the sliding of the headrest body 2. The fabric cover 5 wraps around the back frame 1 and is relatively complete in appearance. Furthermore, the headrest body 2, the back frame 1, and the fabric cover 5 are relatively compact, resulting in a good overall appearance for the seat and a simple and elegant aesthetic.

[0032] Among them, the front end of the back frame 1 is a concave arc surface, and the width of the headrest body 2 is similar to that of the back frame 1. The headrest body 2 is an arc structure that fits the back frame 1, making the seat more integrated and simple in appearance.

[0033] Please refer to the attached document. Figure 4-5 In some embodiments of this application, the sliding structure includes a mounting member 3 and a sliding member 4. The mounting member 3 is recessed and provided with a groove 310 extending in the vertical direction. The sliding member 4 is slidably connected to the mounting member 3 through the groove 310. The mounting member 3 is connected to one of the headrest body 2 and the mounting part 110, and the sliding member 4 is connected to the other of the headrest body 2 and the mounting part 110.

[0034] In this embodiment, a groove 310 is provided on the mounting component 3 to accommodate and support the sliding component 4 to slide up and down. This satisfies the sliding adjustment of the headrest body 2 while making the structure between the mounting component 3 and the sliding component 4 more compact and less likely to be exposed.

[0035] Please refer to the attached document. Figure 4-5 In some embodiments of this application, the mounting member 3 is connected to the rear end of the headrest body 2, the sliding groove 310 is formed at the front end of the mounting member 3, the bottom of the sliding groove 310 is hollowed out to form a connecting groove 311, and the sliding member 4 and the mounting part 110 are detachably connected by screws, the screws pass through the sliding member 4 and the connecting groove 311 and are screwed to the mounting part 110.

[0036] In this embodiment, when assembling the seat, first, the fabric cover 5 is placed on the back frame 1, with the mounting portion 110 at the front of the back frame 1 exposed in the clearance opening 501. Then, the sliding member 4 is inserted into the sliding groove 310 on the mounting member 3, and the mounting member 3 is placed on the front side of the back frame 1, so that the sliding member 4 and the mounting portion 110 are aligned. Then, a screw is screwed in, the screw passing through the sliding member 4 and the connecting groove 311 and screwed into the mounting portion 110, thereby fixing the sliding member 4 and the mounting member 3 together to the mounting portion 110. Finally, the mounting portion 110 is installed on the front end of the mounting member 3 to complete the seat assembly operation. Thus, not only is the connection strength high, but the seat assembly operation is also relatively simple.

[0037] Preferably, the mounting component 3 is a plate-shaped part with a shape similar to that of the headrest body 2. The mounting component 3 is electroplated, giving it a bright metallic luster. It is sandwiched between the darker-colored headrest body 2 and the fabric cover 3, creating a layered appearance and enhancing the aesthetics of the headrest. The front end of the mounting component 3 is fixed with multiple pear-shaped buckles 320, and the rear end of the headrest body 2 has several buckle slots 210. When the headrest body 2 is installed onto the mounting component 3, the pear-shaped buckles 320 and the buckle slots 210 engage seamlessly, resulting in simple assembly and a strong connection.

[0038] Please refer to the attached document. Figure 4-5 In some embodiments of this application, the sliding structure further includes a limiting member 410 and several limiting grooves 312. The limiting member 410 is disposed in one of the mounting member 3 and the sliding member 4, and the several limiting grooves 312 are formed in the other of the mounting member 3 and the sliding member 4. When the sliding member 4 slides up and down, the limiting member 410 engages with the several limiting grooves 312 in sequence. This allows the sliding adjustment of the headrest body 2 to have a tactile feedback, and the headrest body 2 can be suspended at multiple vertical heights.

[0039] Please refer to the attached document. Figure 4-5 In some embodiments of this application, the bottom of the groove 310 is hollowed out to form a connecting groove 311. The sliding member 4 includes a connecting portion 420 that engages with the connecting groove 311. A plurality of limiting grooves 312 are recessed on the groove wall of the connecting groove 311, and the limiting member 410 is correspondingly connected to the side wall of the connecting portion 420. The sliding member 4 is engaged with the connecting groove 311 through the connecting portion 420, which not only further enhances the connection strength between the sliding member 4 and the mounting member 3, but also makes it easier to process the limiting grooves 312 which are recessed in the groove wall of the connecting groove 311, and allows for more limiting grooves 312 to be engaged with the limiting grooves 410.

[0040] Preferably, the connecting groove 311 has at least five limiting grooves 312 on its groove wall, meaning the headrest body 2 has at least five adjustable positions, providing a high degree of adjustment freedom. Furthermore, the connecting groove 311 has recessed limiting grooves 312 on both the left and right sides, and the connecting part 420 also has two limiting members 410 on the left and right sides, further improving the connection stability between the sliding member 4 and the mounting member 3, making the adjustment operation of the headrest body 2 smoother and more stable.

[0041] Please refer to the attached document. Figure 5 In some embodiments of this application, a mounting hole 421 is recessed on the side wall of the connecting part 420, and the limiting member 410 is engaged with the connecting part 420 through the mounting hole 421, and the limiting member 410 can slide left and right along the mounting hole 421.

[0042] In this embodiment, the limiting member 410 is a ball-shaped structure. By inserting the limiting member 410 into the mounting hole 421, the connection stability between the limiting member 410 and the connecting part 420 is better, and the limiting member 410 is not easy to fall off the connecting part 420 during the adjustment process.

[0043] In some embodiments of this application, an elastic element is provided in the mounting hole 421, and the elastic element pushes the limiting element 410 so that the limiting element 410 always tends to be inserted into the limiting groove 312.

[0044] In this embodiment, under the elastic force of the elastic element, the limiting member 410 can not only stably engage with the limiting groove 312, but also exhibits good stability. Furthermore, during the sliding adjustment process, the limiting member 410 can automatically disengage from the limiting groove 312 and engage with the next limiting groove 312 by means of the deformation of the elastic element, thereby making the sliding adjustment operation of the headrest body 2 simpler. Preferably, the elastic element is a spring, which is inexpensive and easy to install into the mounting hole 421.

[0045] In this application, the limiting member 410 may also adopt other structures:

[0046] Please refer to the attached document. Figure 7-8 In some embodiments of this application, the limiting member 410 has elastic deformation capability, and the limiting member 410 moves between several limiting grooves 312 by means of its own elastic deformation. By using a limiting member 410 with elasticity, not only is the connection stability between the limiting member 410 and the limiting grooves 312 stronger, but the limiting member 410 also moves smoothly between the various limiting grooves 312, making the sliding adjustment operation of the headrest body 2 more convenient.

[0047] Please refer to the attached document. Figure 7-8 In some embodiments of this application, the sliding member 4 includes a sliding part 430 and a connecting part 420 that are spliced ​​together. The sliding part 430 is engaged with the sliding groove 310. The front end of the connecting part 420 also protrudes to form a connecting post 422. The limiting member 410 is an elastic rubber washer. The limiting member 410 is engaged with the connecting part 420 through the connecting post 422 and is clamped between the connecting part 420 and the sliding part 430.

[0048] In this embodiment, the limiting member 410 is a rubber washer, which not only has good elastic deformation capability, but also a high coefficient of friction, making the sliding adjustment operation of the headrest body 2 not only smooth but also generating less noise. Furthermore, by setting the sliding member 4 as a split structure, the limiting member 410 is snapped into the connecting part 420 via the connecting post 422 and clamped between the connecting part 420 and the sliding part 430, resulting in high connection strength and convenient assembly. Moreover, the width of the connecting part 420 is greater than the connecting groove 311, allowing the mounting member 3 to be clamped between the connecting part 420 and the sliding part 430, with the sliding member 4 and the mounting member 3 relatively fixed in the horizontal direction, further enhancing the connection strength.

[0049] Please refer to the attached document. Figure 4 and attached Figure 7 In some embodiments of this application, a plurality of hooks 440 are provided on the side wall of the sliding member 4. The hooks 440 have elastic deformation capability, and the sliding member 4 abuts against the groove wall of the sliding groove 310 through the hooks 440.

[0050] In this embodiment, by providing an elastic hook 440 on the side wall of the slider 4 to abut against the side wall of the slide groove 310, the slider 4 can be stably engaged in the slide groove 310, and the connection strength between the slider 4 and the mounting part 3 is higher, thereby enhancing the damping feel when the slider 4 is adjusted, so that the headrest body 2 will not easily slide under the action of external force, and can be stably suspended at the current position, with better stability.

[0051] Preferably, hooks 440 are provided at all four corners of the sliding member 4 to ensure the connection strength between the sliding member 4 and the mounting member 3.
