Description

Technical Field

[0001] This application relates to the field of seat structure technology, and more particularly to a headrest with a snap-fit ​​function and a folding seat. Background Technology

[0002] The headrest is a comfort feature of a seat, located at the top of the seat back. It supports the user's head during use, providing a comfortable seating experience. In existing folding seats, the seat back can be unfolded and folded away relative to the seat surface. Therefore, the headrest also needs to be folded away when the seat is folded.

[0003] Existing folding chairs typically fold down by flipping the headrest and sandwiching it between the folded backrest and seat. Some chairs rely solely on a damping mechanism at the hinges to maintain the folded position. However, for portable folding chairs intended for easy transport, such as outdoors, the damping mechanism may not provide sufficient resistance during transport. The backrest and seat, limited only by the damping mechanism, can easily unfold, causing inconvenience.

[0004] Therefore, existing technologies still need to be improved and developed. Utility Model Content

[0005] In view of the shortcomings of the prior art, the purpose of this application is to provide a headrest with a buckle function and a folding seat, which solves the problem that the folded backrest and seat surface of some folding seats in the prior art are easy to unfold when moving.

[0006] On one hand, this application provides a headrest with a snap-fit ​​function for mounting on the backrest of a seat body. The backrest and seat surface of the seat body are foldable and have a folded state and an unfolded state. The headrest with the snap-fit ​​function includes:

[0007] The headrest body is hinged and can be flipped onto the backrest, and the headrest body has a headrest side;

[0008] A snap-fit ​​part is provided on the headrest body;

[0009] When the seat body is folded, the headrest body rotates to engage with the mating part of the seat surface.

[0010] When the seat body is in the unfolded state, the headrest body rotates so that the headrest side faces the front of the seat body.

[0011] Optionally, the snap-fit ​​portion includes a snap hook, and the mating portion of the seat surface includes a snap groove;

[0012] When the seat body is folded, the hooks are engaged in the slots by flipping the headrest body.

[0013] Optionally, the headrest body also has a back side opposite to the headrest side, and a hook is provided on the back side;

[0014] The card slot is located on the front of the seat.

[0015] Optionally, the hook includes: a connecting block, which is vertically disposed on the rear side;

[0016] The hook body is set on the connecting block so that a hook opening is formed between the hook body and the back side of the headrest body, with the hook opening facing the hinge part.

[0017] The end of the hook that faces away from the connecting block has an arc-shaped surface.

[0018] Optionally, the headrest body includes: a base frame, one side of which is hinged to the backrest;

[0019] An arc-shaped support frame is installed on the base frame, and the side facing away from the base frame has an arc-shaped surface.

[0020] Optionally, a flexible pad is provided on the curved surface of the curved support frame.

[0021] Optionally, a hollow area is provided between the base frame and the arc-shaped support frame.

[0022] Optionally, the hinge portion includes: two lugs, which are spaced apart on one side of the headrest body portion, and a hinge space is formed between the two lugs;

[0023] A hinge rod passes between two lugs and through a hinge platform located on the backrest in the hinge space.

[0024] Optionally, an adjustment member is connected to the hinge platform on the backrest. The adjustment member is movably mounted on the backrest, and the height of the headrest body can be adjusted by adjusting the relative position of the adjustment member and the backrest.

[0025] On the other hand, this application also proposes a folding seat, including a seat body and a headrest with a buckle function as described above;

[0026] The seat body includes a seat surface and a backrest, the backrest and seat surface being foldable so that the seat body can be in a folded state and an unfolded state;

[0027] The headrest body can be flipped up and mounted on the backrest.

[0028] Beneficial Effects: This application discloses a headrest with a snap-fit ​​function and a folding seat. By hinged the headrest body to the backrest, the headrest body can be flipped up, and a snap-fit ​​part is provided on the headrest body. When the seat body is folded, the headrest body rotates to engage the snap-fit ​​part with the mating part of the seat surface. When the seat body is unfolded, the headrest body rotates to move the headrest side away from the backrest. In this way, the headrest not only provides support for the user's head but also snaps onto the seat surface through the snap-fit ​​part, ensuring a stable folding connection between the folded backrest and seat surface. This locks the headrest in place during transport or folded storage, preventing the backrest and seat surface from unfolding and improving the portability and stability of the folded seat.

[0035] To make the objectives, technical solutions, and advantages of this application clearer and more explicit, the following detailed description of this application is provided with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of this application and are not intended to limit this application.

[0036] Example 1

[0037] like Figure 1 , Figure 2 , Figure 3 As shown, this embodiment proposes a headrest 10 with a snap-fit ​​function, which is used to mount on a seat body 20. The seat body 20 includes a foldable backrest 21 and a seat surface 22. When the seat body 20 is in use, the seat surface 22 supports the user's body, the backrest 21 supports the user's back, and the headrest 10 is mounted on the backrest 21 to support the user's head. The backrest 21 and the seat surface 22 are foldable, allowing the seat body 20 to have a folded state and an unfolded state. For ease of structural description, the left-right, front-back, and up-down directions of the seat body 20 in use are used as the directions for structural description in this embodiment. The backrest 21 is rotatably mounted on the seat surface 22 about a left-right pivot, thereby realizing the folding and unfolding of the seat body 20.

[0038] like Figure 1 , Figure 3 As shown, the headrest 10 with a snap-fit ​​function in this embodiment mainly includes: a headrest body 100 and a snap-fit ​​part 200. The headrest body 100 is rotatably mounted on the backrest 21 via a hinge part 300. The headrest body 100 has a headrest side 101 and a backrest side 102, which are arranged opposite to each other. The headrest side 101 is the side of the headrest body 100 that supports the user's head, and the snap-fit ​​part 200 is provided on the headrest body 100. Figure 2 As shown, in the folded state of the seat body 20, the headrest body 100 rotates to engage the locking portion 200 with the mating portion 23 of the seat surface 22. Figure 1 As shown, when the seat body 20 is in the unfolded state, the headrest body 100 rotates so that the headrest side 101 is away from the backrest 21. This allows the headrest side 101 to be flipped forward, enabling the user's head to rest against the headrest side 101 when sitting on the seat body 20, thus providing a headrest function. Therefore, by hinged to the backrest 21, the headrest body 100 can be flipped, and a locking part 200 is provided on the headrest body 100. When the seat body 20 is in the folded state, the headrest body 100 rotates so that the locking part 200 engages with the mating part 23 of the seat surface 22, thereby locking the backrest 21 and the seat surface 22. When the seat body 20 is unfolded, the headrest body 100 rotates so that the headrest side 101 moves away from the backrest 21. In this way, the headrest 10 not only supports the user's head, but also enables the unfolded seat body 20 to be used normally.

[0039] The headrest 10 with a snap-fit ​​function in this embodiment not only supports the user's head by flipping it over, but also snaps onto the seat 22 via the snap-fit ​​part 200, allowing the folded backrest 21 and seat 22 to be stably connected via the headrest body 100. This connection and locking mechanism of the headrest 10 prevents the backrest 21 and seat 22 from unfolding during transport, handling, or storage, thus improving the portability and stability of the folded chair.

[0040] like Figure 3 As shown, in this embodiment, the latching portion 200 specifically includes a latch 210, and the mating portion 23 of the seat surface 22 includes a latching groove 24. When the seat body 20 is folded, the latch 210 is engaged in the latching groove 24 by flipping the headrest body portion 100. The use of the latch 210 and latching groove 24 simplifies the locking structure and makes it more convenient to use. Figure 1 As shown, when the seat body 20 is in the unfolded state, the headrest body 100 is flipped up and down, causing the headrest side 101 of the headrest body 100 to flip forward, thus concealing the hook 210. Figure 2 As shown, when the seat body 20 is in a folded state, by flipping the headrest body 100 up and down, the hook 210 can be hooked into the slot 24 and is not easy to fall off, thereby stably locking the folded backrest 21 and seat body 22.

[0041] like Figure 3 , Figure 4 , Figure 5 As shown, in this embodiment, the hook 210 of the headrest body 100 is provided on the back side 102; the slot 24 is opened at the front end of the seat surface 22, for example, it can be on the front side of the seat surface 22, or it can be at the front end of the upper surface of the seat surface 22. By providing the hook 210 on the back side 102, the headrest side 101 of the headrest body 100 can face forward, while the hook 210 is hidden on the back, which does not affect the normal use of the headrest body 100. By opening the slot 24 on the front side, the hook 210 can hook onto the upper wall of the slot 24 during the flipping process to achieve a locking function. When the headrest body 100 is hooked and locked, the width of the headrest body 100 matches the thickness of the folded backrest 21 and seat surface 22, which will not increase the thickness of the folded seat body 20, making the shape of the folded seat body 20 more harmonious.

[0042] like Figure 1 , Figure 3As shown, since the hook 210 is located on the back of the headrest body 100 in the unfolded state, a top support 25 can be provided inside the backrest 21 at a position corresponding to the hook 210. The top support 25 can provide abutment support for the hook 210, ensuring the hook 210's support for the headrest body 100. The top support 25 can also be a groove, allowing the hook 210 to be inserted into the groove and abut against the bottom of the groove, achieving stable support while also concealing the hook 210.

[0043] like Figure 3 , Figure 4 , Figure 5 As shown, the hook 210 in this embodiment further includes a connecting block 211 and a hook body 212. The connecting block 211 is vertically disposed on the back side 102, and the hook body 212 is disposed on the connecting block 211 and extends a predetermined length toward the hinge portion 300 so as to stably hook onto the slot 24. The hook opening formed between the hook body 212 and the back side 102 of the headrest body 100 faces the hinge portion 300. By flipping the headrest body 100, the hook body 212 can be inserted into the slot 24 to achieve a stable connection. In this embodiment, the end of the hook body 212 facing away from the connecting block 211 has an arc-shaped surface 213. During the flipping process of the headrest body 100, the hook body 212 can stably cooperate with the slot opening of the slot 24 through the arc-shaped surface 213, so that the hook body 212 can smoothly slide into the slot 24 through the guiding effect of the arc-shaped surface 213 to achieve the hooking function. During the flipping process of the headrest body 100, as the hook 212 disengages from the slot 24, the hook 212 can be smoothly flipped out of the slot 24 through the anti-airing effect of the arc surface 213, thus making the use of the hook 210 smoother.

[0044] In this embodiment, two hooks 210 can be provided. The two hooks 210 are spaced apart on the back side 102 of the headrest body 100 in the left and right directions. This way, the hook function can be realized in both the left and right directions, making the connection of the folded seat body 20 more stable, and the folded backrest 21 and seat surface 22 are not easy to loosen.

[0045] like Figure 3 , Figure 4 , Figure 5As shown, the headrest body 100 of this embodiment further includes a base frame 110 and an arc-shaped support frame 120. One side of the base frame 110 is hinged to the backrest 21, and the arc-shaped support frame 120 is disposed on the base frame 110 with an arc-shaped surface on the side facing away from the base frame 110. In the specific structure, the arc-shaped support frame 120 and the base frame 110 can be integrally formed, the surface of the base frame 110 is the back side 102, and the hook 210 is fixedly disposed on the base frame 110. The base frame 110, the hook 210, and the arc-shaped support frame 120 are integrally formed, thereby giving the headrest body 100 an arched design, which improves the structural strength of the headrest body 100 and gives it better load-bearing capacity. The headrest side 101 of the arc-shaped support frame 120 has an arc-shaped surface. By bending the surface, the protrusion height can be increased, thereby matching the contour of the user's neck and head, and giving the user a more comfortable experience.

[0046] like Figure 3 , Figure 4 As shown, in this embodiment, a flexible pad 130 is further provided on the arc-shaped surface of the arc-shaped support frame 120. The use of the flexible pad 130 increases the user's comfort.

[0047] like Figure 2 , Figure 3 As shown, in this embodiment, a hollow area 121 is further provided between the base frame 110 and the arc-shaped support frame 120. The hollow area 121 allows the arched headrest body 100 to better distribute pressure from the user's head. It also reduces the overall weight of the headrest body 100, improving portability. While maintaining good load-bearing capacity, it ensures product quality and saves materials and costs.

[0048] like Figure 3 , Figure 4 , Figure 5 As shown, the hinge portion 300 in this embodiment further includes two lugs 310 and a hinge rod 320. The two lugs 310 are spaced apart on one side of the headrest body portion 100, forming a hinge space between them; the hinge rod 320 passes between the two lugs 310 and through a hinge platform 410 located on the backrest 21 in the hinge space. The hinge function of the headrest body portion 100 is realized through the cooperation of the hinge platform 410 and the hinge portion 300. The lugs 310 on both sides are integrally formed with the base frame 110 and the arc-shaped support frame 120, and the lugs 310 extend into the hollow area 121 of the arc-shaped support frame 120 and connect to the arc-shaped support frame 120. In this way, the lugs 310 also serve as reinforcing ribs, connecting the base frame 110 and the arc-shaped support frame 120, thereby improving the structural strength of the entire headrest body portion 100.

[0049] like Figure 3 , Figure 4As shown, in this embodiment, the hinge platform 410 on the backrest 21 is connected to an adjustment member 400. The adjustment member 400 is movably disposed on the backrest 21, and the height of the headrest body 100 can be adjusted by controlling the relative position of the adjustment member 400 and the backrest 21. In the unfolded state, the adjustment member 400 can be moved and locked in the vertical direction, thereby driving the headrest body 100 hinged thereto to move vertically, realizing the adjustment of the vertical position of the headrest body 100 to adapt to the user's actual usage needs. When folding is required, the headrest body 100 is lowered to the initial position via the adjustment member 400, then the backrest 21 is flipped over, and finally the headrest body 100 is flipped over so that the locking part 200 can be connected to the seat surface 22.

[0050] Example 2

[0051] like Figure 1 , Figure 2 , Figure 3 As shown, this embodiment proposes a folding seat, including a seat body 20 and a headrest 10 with a buckle function as described above. The seat body 20 includes a seat surface 22 and a backrest 21. The backrest 21 and the seat body 20 are foldable, so that the seat body 20 has a folded state and an unfolded state.

[0052] The headrest body 100 is flip-up and mounted on the backrest 21. A locking part 200 is provided on the headrest body 100, allowing the headrest 10 to not only support the user's head but also to lock onto the seat 22 via the locking part 200. This ensures a stable folding connection between the folded backrest 21 and seat 22. During transport, handling, or storage, the locking mechanism of the headrest 10 prevents the backrest 21 and seat 22 from unfolding, improving the portability and stability of the folded chair.
