Description

Technical Field

[0001] The utility model relates to the technical field of headrests, in particular to a seat headrest. Background Art

[0002] People install headrests on seats to improve the comfort when leaning and reduce fatigue caused by sitting for a long time. With the development of society, people have higher and higher requirements for comfort. Seats include various structures such as headrests and no headrests. In work and life, people choose seats with different structures according to their different requirements for comfort.

[0003] According to the Chinese patent with publication number: CN204378539U, a seat headrest includes a headrest and a pair of headrest fixing straps connected to one side of the headrest, the headrest fixing straps are respectively connected with a Japanese-shaped buckle, the Japanese-shaped buckle is fixed to the back of the headrest by connecting feet connected to both ends thereof, so that a gap is left between the Japanese-shaped buckle and the headrest; the connecting foot includes a connecting bridge with a middle protrusion in the shape of a "door" and two fixing parts at the bottom of the connecting part, the fixing part is fixedly connected to the headrest, and the Japanese-shaped buckle is connected to the inner wall of the connecting bridge.

[0004] In the above solution, the headrest adopts a fixing belt with a relatively rough surface to increase friction, which still causes the following disadvantages: since the interior of the headrest is filled with a large amount of solid objects, when used in hot weather, the comfort of the pillow may decrease due to lack of air permeability. Utility Model Content

[0005] The utility model aims to provide a seat headrest to solve the problem that the headrest is filled with a large amount of real objects and the pillow may be less comfortable to use in hot weather due to insufficient air permeability.

[0006] In order to achieve the above-mentioned purpose of the utility model, the utility model adopts the following technical scheme: a seat headrest, including a fixing plate, intercepting plates are respectively fixed on both sides of the fixing plate, two fixing strips are detachably arranged between the two intercepting plates, a breathable layer is fixed between the two fixing strips, sliding grooves are respectively provided on both sides of the two intercepting plates close to each other, a limiting groove is provided on one side of the inner side of the sliding groove, a connecting strip is fixed on one side of the fixing strip, a limiting column is fixed on one side of the connecting strip, the limiting column is slidably inserted in the limiting groove, the connecting strip is slidably inserted in the sliding groove, and filling material is slidably arranged between the two intercepting plates.

[0007] Preferably, a shielding cover is fixed between the two fixing strips, a Velcro mother surface is fixed to one side of the shielding cover, and a Velcro sub-surface is fixed to one side of the fixing plate.

[0008] Preferably, two blocking strips are fixed to the top surface of the filling material, and an elastic plate is fixed to one side of the intercepting plate.

[0009] Preferably, two positioning plates are fixed on one side of the fixed plate, a support plate is rotatably arranged between the two positioning plates, a through hole is opened on one side of the positioning plate, a through hole is opened on one side of the support plate, a limit pin is rotatably inserted inside the through hole, and one end of the limit pin passes through the through hole and is rotatably inserted with the through hole.

[0010] Preferably, two positioning columns are fixed on the surface of the limit pin, and two extrusion disks are arranged on the surface of the limit pin. A rotating hole is opened on the top surface of the extrusion disk, and the rotating hole and the positioning column are rotatably inserted. A push plate is fixed on the surface of the extrusion disk.

[0011] Preferably, a plurality of threaded holes are opened on one side of the support plate, the inner threads of the threaded holes are connected with fixing bolts, and the surfaces of the fixing bolts are connected with threaded rings.

[0012] Compared with the prior art, a seat headrest adopting the above technical solution has the following beneficial effects:

[0013] 1. The user will first install the fixing plate and the back of the seat together. Then, when the user sits on the seat, the back of the user's head will lean against the surface of the breathable layer. When the surface of the breathable layer is stained due to long-term use, the user will first move the fixing strip upwards. The upward fixing strip will drive the connecting strip and the limiting column to disengage from the sliding groove and the inside of the limiting groove, making it easier to remove the breathable layer for cleaning. When the user uses the seat in hot weather, the user will first take out the filling material to make the space between the breathable layer and the fixing plate hollow, so that the breathable layer made of mesh cloth with better breathability can be used to increase the user's comfort when using the seat;

[0014] Second, when the filling material is placed between the two interception plates, the blocking strips on the top of the filling material will hold the filling material on the two interception plates, thus fixing the position of the filling material and preventing it from falling off. When the back of the user's head contacts the surface of the breathable layer, the two interception plates are located on both sides of the user's head, preventing the user from getting a stiff neck due to the excessive tilt of the head after falling asleep, thus increasing safety during use.

[0015] 3. The user will first pass the fixing bolt through the chair back, then screw it into the inside of the threaded hole and pass it through the threaded hole. After the fixing bolt passes through the threaded hole, it will be screwed into the threaded ring on the surface to fix the support plate on the chair back. In order to adapt to different users, the user will first turn the push plate to make the push plate and the limit pin parallel to each other. In this process, the distance between the rotating hole and the positioning plate will gradually shorten, and the angle of the fixing plate can be adjusted. After the adjustment, the user will reset the push plate again, and corresponding adjustments can be made according to different users, thereby increasing the applicability of the chair head being corrected.

[0023] During use, the user will first install the fixing plate 1 together with the back of the seat, and then when the user sits on the seat, the back of the user's head will lean against the surface of the breathable layer 4. When the surface of the breathable layer 4 is dirty due to long-term use, the user will first move the fixing strip 3 upwards. The upward moving fixing strip 3 will drive the connecting strip 7 and the limiting column 8 to disengage from the sliding groove 5 and the inside of the limiting groove 6, so that the breathable layer 4 can be removed for cleaning. When the user uses the seat in hotter weather, the user will first take out the filling material 9, so that the breathable layer 4 and the fixing plate 1 are in a hollow state, so that the breathable layer 4 made of mesh cloth with better air permeability can be used to increase the user's comfort when using the seat.

During this process, the distance between the rotating hole 20 and the positioning plate 14 will gradually shorten, and the angle of the fixing plate 1 can be adjusted. After the adjustment, the user will reset the push plate 21, and corresponding adjustments can be made according to different users, thereby increasing the applicability of the chair head being corrected.

[0028] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto.
