[0001] The utility model relates to the technical field of installation and connection of a headrest added to a seat, in particular to a connection structure of a headrest for an automobile seat. Background Art

[0002] Many car manufacturers currently equip their original car seats with a main headrest that is set to electrically lift and slide along the seat back. However, this type of main headrest is often not very comfortable, so many car owners will still purchase and install another headrest on the outside of this main headrest. Normally, if you want to add a neck pillow to the seat back, it is relatively easy to just put it on the plug rod of the seat back. However, it is relatively not that easy to do with a headrest because the main headrest will also slide up and down. Therefore, it needs to slide up and down with the main headrest, and cannot be directly tied to the seat back with an elastic band, which will limit the sliding of the main headrest.

DETAILED DESCRIPTION

[0027] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0028] refer to Figures 1 to 8 :

[0029] The utility model discloses a car seat headrest connection structure, comprising a seat back 1, a main headrest 2, the main headrest 2 can be slidably installed on the upper end of the seat back 1 (existing technology), the upper end inner side (close to the side of the seat back 1) of the main headrest 2 has a first connection position 21, the lower end has a second connection position 22, and also includes an additional headrest 3, the upper end inner side of the additional headrest 3 is provided with an upper connection belt 31, the lower end inner side is provided with a lower connection belt 32, wherein the upper connection belt 31 is connected and installed with the first connection position 21 through a first connecting member 4, and the lower connection belt 32 is connected and installed with the second connection position 22 through a second connecting member 5, Specifically, the second connection position 22 is one of a male or female snap button, the second connection piece is one of a female or male snap button, which is located at the end of the lower connecting belt 32, and the second connection position 22 is arranged at the bottom inner side of the main headrest 2; or, the second connection position 22 is one of a hook side or a fur side of Velcro, the second connection piece is one of a fur side or a hook side of Velcro, which is located at the end of the lower connecting belt 32, and the second connection position 22 is arranged at the bottom inner side of the main headrest 2, so that the main headrest 2 and the lower end of the additional headrest 3 are connected by a snap button or Velcro.

[0030] Embodiment 1: The first connecting position 21 is an L-shaped hook groove, which is formed by a depression outward on one side of the main headrest 2 close to the seat back 1. The first connecting member 4 is a hook that hooks with the L-shaped hook groove. The hooking position of the hook faces the step position of the L-shaped hook groove. The hook is fixedly connected to the end or free end of the upper connecting belt 31.

[0031] As other preferred embodiments, the installed headrest 3 will fall downward due to its own weight, and at this time, the hook and the L-shaped hook groove itself can be hooked together. However, in some cases, if the car is too bumpy, or a person pushes it slightly upward, the ordinary hook and the L-shaped hook groove may cause the upper end of the installed headrest 3 to be detached from the second connecting position 22. Then an improved solution is provided here, specifically: the hook has an arc-shaped hooking portion 41, and the hook groove is provided with a hooking groove 211 at the position corresponding to the hooking portion 41, and an acute angle is formed between the hooking portion 41 and the main body of the hook, and the hooking groove 211 is adapted to an angle of the hooking portion 41 to be hooked in, so that the upper end of the installed headrest 3 can be limited from shaking in the left and right directions, and at the same time, the upper and lower directions will also be limited.

[0032] Continuing with the description of the problem in the previous paragraph, for the additional headrest 3 with its own weight, when the head rests on the additional headrest 3, there will be part of the compression force pressing inwards, which will cause the additional headrest 3 to be partially concave. If the upper connecting strap 31 is made of hard material, it will produce a hard pull on the hook. Here, the upper connecting strap 31 is an elastic strap, and the hook is made of plastic. The elastic strap and the hook are bonded by hot melt adhesive. The elastic strap can allow the upper connecting strap 31 to have a buffering effect, which can effectively protect the hook from being easily damaged.

[0033] Embodiment 2: The first connecting position 21 is a snap-fitting slot structure with an opening cover 212 and a snap-fitting cavity 213, the opening cover 212 can be closed and arranged at the notch of the snap-fitting slot, the end of the upper connecting belt 31 is provided with a snap-fitting joint 42 downwardly, the snap-fitting joint 42 has an enlarged portion 421 and a clamping portion 422, the enlarged portion 421 is located at the lower end of the clamping portion 422 and the diameter of the enlarged portion 421 is larger than the diameter of the clamping portion 422, when the snap-fitting joint 42 is inserted into the snap-fitting cavity 213 of the snap-fitting slot, the enlarged portion 421 is embedded in the snap-fitting cavity 213 and the clamping portion 422 is just clamped with the notch of the snap-fitting slot.

[0034] Specifically, a hinge base 214 is provided at the inner end surface of the clamping cavity 213, and a first hinge hole 215 and a hinge groove 216 are provided on the hinge base 214. A rotating arm 217 is integrally formed on one side of the opening cover 212, and a hinge block 218 is provided at the position of the rotating arm 217 corresponding to the hinge groove 216. A second hinge hole 219 is provided on the hinge block 218, and a reset torsion spring 230 is also included. One output end of the reset torsion spring 230 abuts on the inner end surface of the clamping cavity 213, and the other output end abuts on the rotating arm 217. Finally, the opening cover 212 is rotatably installed on the inner side of the clamping groove through the reset torsion spring 230, the second hinge hole 219 and the first hinge hole 215 through the hinge shaft 231. When it is needed When it is to be connected, the card connector 42 is inserted into the card connector groove. At this time, the opening cover 212 is squeezed and shrinks inward, and compresses the reset torsion spring 230. When the card connector 42 completely enters the card connector cavity 213 inside the card connector groove, the card connector 42 is not easy to fall out because of the upward force of the opening cover 212, which is equivalent to a locking effect. It is not easy to pull the card connector 42 out of the card connector groove when the head rests on the installed headrest 3 in daily life. When it needs to be pulled out, it needs to be pulled out with force. Specifically, the card connector 42 is preferably made of soft silicone, and the hardness of the silicone can be adjusted by factory adjustment, so as to adjust the tightness of the card connector 42 inserted into the card connector groove. The notch of the card connector groove is preferably tempered or plasticized.

[0035] Embodiment 3: On the basis of Embodiment 2, an anti-lost line is provided between the notch of the snap-in slot and the opening cover 212. The anti-lost line is preferably made of soft rubber. Here, the opening cover 212 is directly connected with an anti-lost line. When the snap-in connector 42 needs to be inserted, the opening cover 212 is buckled out and the snap-in connector 42 is inserted. When the snap-in connector 42 does not need to be connected, the opening cover 212 is covered. The covering method can adopt a step-fitting method, or a groove-protrusion-fitting method (or other covering methods in the prior art).

[0036] Specifically, because the main headrest 2 and the seat back 1 are generally in a close fit when they are connected, when the lower connecting strap 32 needs to be connected to the second connecting position 22, it is necessary to pry open a portion of the lower end of the main headrest 2, which is obviously difficult. A solution is proposed herein, in which an avoidance groove 101 is provided on one side of the lower end of the seat back 1 to facilitate the installation of the lower connecting strap 32 and the second connecting position 22 by hand.

[0037] As mentioned above, it should be pointed out that the four-button or Velcro at the lower end of the main headrest 2 can be made in the form of cooperation with the manufacturer before leaving the factory, or can be installed later, such as by fixing it with 502 glue. The L-shaped hook groove in Example 1 or the snap-in groove in Example 2 can also be made in the form of cooperation with the manufacturer before leaving the factory. Of course, this can also be installed later, or the main headrest 2 can be directly replaced. It is preferred to have such a structure ready when the car seat leaves the factory, which is convenient for direct installation later. This can also better promote the selling points of the seat manufacturers.

[0038] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
