Abstract
Description
Technical Field
[0001] This utility model relates to the field of seat backrest technology, specifically an adjustable seat backrest. Background Technology
[0002] A chair is a type of seating with a backrest, and some chairs also have armrests. A backrest is used to adjust the contact point between the human body and the chair to obtain a more comfortable angle and reduce fatigue. Because backrests are convenient and flexible to use, they are suitable for various occasions and environments. Backrests are also needed during the use of chairs. However, existing backrests have some shortcomings in use. In order to meet market needs, an adjustable backrest is required.
[0003] Existing seat backrests are inconvenient to fix after adjustment, and their stability and anti-slip performance are not good enough. This reduces the stability of the seat backrest when it is installed on the seat, and it is easy to loosen during use. In addition, existing seat backrests usually cannot be adjusted to the correct position and fixed during use. This means that after the backrest body and connecting plate are adjusted up and down, they cannot automatically fix their positions. Utility Model Content
[0004] The purpose of this utility model is to provide an adjustable seat pillow to solve the problems mentioned in the background art, such as the insufficient stability and anti-slip performance of seat pillows during use, and the inability to adjust and fix them in place.
[0005] To achieve the above objectives, the present invention provides the following technical solution: an adjustable seat backrest, including a backrest holder, a fixing sleeve installed on one side of the surface of the backrest holder, a connecting plate provided on one side of the backrest holder, a stabilizing and anti-detachment mechanism provided on the inner wall of the backrest holder, and an adjustment and fixing mechanism provided on the surfaces of the connecting plate and the fixing sleeve.
[0006] Preferably, the bottom end of the connecting plate passes through the fixed sliding sleeve and slides against the inner wall of the fixed sliding sleeve. A connecting frame is installed on the surface of the connecting plate, and a pillow body is provided on the surface of the connecting frame. The pillow body and the connecting frame are connected by fastening studs.
[0007] Preferably, the stabilizing and anti-slip mechanism consists of positioning blocks, a silicone pad, a rubber anti-slip pad, and anti-slip protrusions. The inner wall of the pillow holder is provided with a silicone pad, and two sets of positioning blocks are installed on the inner wall of the silicone pad. The positioning blocks are engaged with the inner wall of the pillow holder.
[0008] Preferably, the surface of the silicone pad is fitted with a rubber anti-slip pad, and the surface of the rubber anti-slip pad is arrayed with multiple sets of anti-slip protrusions to improve the stability between the headrest holder and the seat.
[0009] Preferably, the adjustment and fixing mechanism includes a fixing clip, an anti-detachment groove, an anti-detachment block, and a spring piece. The fixing clip is installed on the surface of the connecting plate. Anti-detachment grooves are opened on both sides of the fixing clip. A spring piece is installed on one side of the fixing sleeve.
[0010] Preferably, the spring sheet has a groove inside, one end of the fixing clip extends into the groove, and the inner wall of the groove is equipped with an anti-disengagement block for engaging with the anti-disengagement slot.
[0011] Compared with the prior art, the beneficial effects of this utility model are: the adjustable seat pillow not only makes the seat pillow more stable when installed on the seat and less likely to come loose during use, but also allows the headrest body and connecting plate to be automatically fixed in position after being adjusted up and down.
[0012] 1. By incorporating a stabilizing and anti-detachment mechanism, the headrest holder is secured to the seat. Positioning blocks install the silicone pad, rubber anti-slip mat, and anti-slip protrusions onto the inner wall of the headrest holder. The anti-slip protrusions on the rubber anti-slip mat move to contact the seat surface. The combined action of the silicone pad, rubber anti-slip mat, and anti-slip protrusions increases the friction between the headrest holder and the seat, improving the stability of the headrest holder when used on the seat. This achieves the function of stabilizing and preventing the headrest from detaching, resulting in greater stability when the headrest is installed on the seat and reducing the likelihood of it loosening during use.
[0013] 2. By setting an adjustment and fixing mechanism, the headrest body drives the connecting plate to slide up and down on the inner wall of the fixing sleeve. When the connecting plate is adjusted up and down, the fixing clips on the surface of the connecting plate automatically lock into the inside of the groove. Due to the elasticity of the spring, when the fixing clips move into the inside of the spring, they can lock the position of the headrest body and the connecting plate. At this time, the anti-detachment blocks on the inner wall of the spring respectively lock into the surface of the anti-detachment slot. Under the locking action of the anti-detachment slot and the anti-detachment block, the fixing clips and the spring are locked together, so that the headrest body and the connecting plate will not continue to move, realizing the function of fixing the seat headrest in place. Thus, after the headrest body and the connecting plate are adjusted up and down, they can automatically fix the position of the headrest body and the connecting plate. Attached Figure Description

[0022] The present invention provides an adjustable seat pillow with the following structure: Figures 1 to 4 As shown, the device includes a headrest holder 1, a fixed sliding sleeve 15 is installed on one side of the headrest holder 1, a connecting plate 12 is provided on one side of the headrest holder 1, the bottom end of the connecting plate 12 passes through the fixed sliding sleeve 15 and slides against the inner wall of the fixed sliding sleeve 15, a connecting frame 14 is installed on the surface of the connecting plate 12, a headrest body 11 is provided on the surface of the connecting frame 14, and the headrest body 11 and the connecting frame 14 are connected by fastening studs 13.
[0023] Furthermore, such as Figure 4 and Figure 5 As shown, the inner wall of the headrest holder 1 is provided with a stabilizing and anti-slip mechanism 2. The stabilizing and anti-slip mechanism 2 consists of positioning blocks 21, silicone pads 22, rubber anti-slip pads 23, and anti-slip protrusions 24. The inner wall of the headrest holder 1 is provided with silicone pads 22. Two sets of positioning blocks 21 are installed on the inner wall of the silicone pads 22. The positioning blocks 21 and the inner wall of the headrest holder 1 are engaged with each other. The surface of the silicone pads 22 is provided with rubber anti-slip pads 23. The surface of the rubber anti-slip pads 23 is arrayed with multiple sets of anti-slip protrusions 24 to improve the stability between the headrest holder 1 and the seat.
[0024] During implementation, the silicone pad 22, rubber anti-slip pad 23, and anti-slip protrusion 24 are installed on the inner wall of the headrest holder 1 under the action of the positioning block 21. The anti-slip protrusion 24 on the surface of the rubber anti-slip pad 23 moves to contact the surface of the seat. Under the combined action of the silicone pad 22, rubber anti-slip pad 23, and anti-slip protrusion 24, the friction between the headrest holder 1 and the seat can be increased, which can improve the stability of the headrest holder 1 when it is installed on the seat, so as to achieve the function of the seat headrest being stable and preventing it from falling off.
[0025] Furthermore, such as Figure 4 and Figure 6 As shown, the surfaces of the connecting plate 12 and the fixed sliding sleeve 15 are provided with an adjustment and fixing mechanism 3. The adjustment and fixing mechanism 3 includes a fixing clip 31, an anti-detachment groove 32, an anti-detachment block 33, and a spring piece 34. The surface of the connecting plate 12 is equipped with a fixing clip 31. Anti-detachment grooves 32 are provided on both sides of the fixing clip 31. A spring piece 34 is installed on one side of the fixed sliding sleeve 15. A groove 35 is provided inside the spring piece 34. One end of the fixing clip 31 extends into the inside of the groove 35. An anti-detachment block 33 is installed on the inner wall of the groove 35 for engaging with the anti-detachment groove 32.
[0026] During implementation, the headrest body 11 drives the connecting plate 12 to slide up and down on the inner wall of the fixed sliding sleeve 15. When the connecting plate 12 is adjusted up and down into place, the fixing clip 31 on the surface of the connecting plate 12 automatically locks into the inside of the groove 35. Since the spring piece 34 has a certain elasticity, when the fixing clip 31 moves into the inside of the spring piece 34, it can lock the positions of the headrest body 11 and the connecting plate 12. At this time, the anti-detachment clip 33 on the inner wall of the spring piece 34 locks into the surface of the anti-detachment slot 32. Under the locking action of the anti-detachment slot 32 and the anti-detachment clip 33, the fixing clip 31 and the spring piece 34 are locked together, so that the headrest body 11 and the connecting plate 12 will not continue to move, so as to realize the function of fixing the seat headrest in place.
[0027] Working principle: In use, first place the headrest holder 1 in the designated position on the seat, so that the seat moves into the interior of the headrest holder 1. Under the action of the headrest holder 1, the headrest holder 1 is installed between the headrest holder 1 and the seat. Under the action of the positioning block 21, the silicone pad 22, the rubber anti-slip pad 23, and the anti-slip protrusions 24 are installed on the inner wall of the headrest holder 1. The anti-slip protrusions 24 on the surface of the rubber anti-slip pad 23 move to contact the surface of the seat. Under the combined action of the silicone pad 22, the rubber anti-slip pad 23, and the anti-slip protrusions 24, the friction between the headrest holder 1 and the seat can be increased, which can improve the stability of the headrest holder 1 when it is installed on the seat, so as to achieve the function of securing and preventing the seat headrest from falling off. This makes the seat headrest more stable when it is installed on the seat and less likely to fall off during use.
[0028] Subsequently, when the user pulls the headrest body 11 and connecting plate 12 to adjust its height, the headrest body 11 drives the connecting plate 12 to slide up and down on the inner wall of the fixed sliding sleeve 15. When the connecting plate 12 is adjusted up and down into place, the fixing clip 31 on the surface of the connecting plate 12 automatically engages with the inside of the groove 35. Since the spring piece 34 has a certain elasticity, when the fixing clip 31 moves into the inside of the spring piece 34, it can lock the position of the headrest body 11 and the connecting plate 12. At this time, the anti-detachment clip 33 on the inner wall of the spring piece 34 engages with the surface of the anti-detachment slot 32. Under the engaging action of the anti-detachment slot 32 and the anti-detachment clip 33, the fixing clip 31 and the spring piece 34 are locked together, so that the headrest body 11 and the connecting plate 12 will not continue to move, thereby realizing the function of fixing the seat headrest in place. Thus, after the headrest body 11 and the connecting plate 12 are adjusted up and down into place, the position of the headrest body 11 and the connecting plate 12 can be automatically fixed, and the use of the seat headrest is finally completed.
[0029] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
