[0038] In the description of the present invention, it should be clarified that the directional terms "front, back, left, right, up, down, inside, outside" are only relative concepts in terms of direction. They are for the convenience of describing the present invention or simplifying the description, rather than indicating or implying a specific direction that the present invention must have. Therefore, they cannot be understood as limitations on the present invention.

[0039] Embodiment 1

[0040] like Figures 1 to 3 and Figure 6 As shown, the present invention discloses an adaptive neck support, comprising a neck support body A for supporting a human neck and a neck support mounting device for mounting the neck support body on a seat;

[0041] The neck support mounting device is provided with a connecting seat B, a first hook 1, a second hook 2 and a reset mechanism C; one of the first hook 1 and the second hook 2 is located on the left side of the connecting seat B, and the other is located on the right side of the connecting seat B, and the hook portion 1-1 of the first hook 1 is arranged opposite to the hook portion 2-1 of the second hook 2, wherein the attached drawings of the present invention show a structure in which the first hook 1 is located on the left side and the second hook 2 is located on the right side, but the present invention can also adopt a structure in which the first hook 1 is located on the right side and the second hook 2 is located on the left side; the end of the first hook 1, i.e., the first hook end 1-2, is connected to the connecting seat B and can slide relatively in the left and right directions, and the first hook end 1-2 is connected to the connecting seat B through the reset mechanism C, so that the reset mechanism C applies a restoring force F to the first hook 1, and the direction of the restoring force F is from the first hook 1 to the second hook 2, that is: for the case where the first hook 1 is located on the left side and the second hook 2 is located on the right side, the direction of the restoring force F is rightward, and conversely, for the case where the first hook 1 is located on the right side and the second hook 2 is located on the left side, the direction of the restoring force F is leftward; the second hook 2 is connected to the connecting seat B;

[0042] The neck support body A is located in front of the connecting seat B and is connected and fixed to the connecting seat B.

[0043] Therefore, the adaptive neck support of the present invention can be applied to car seats. Taking the structure in which the first hook 1 is located on the left side and the second hook 2 is located on the right side as an example, the use of the present invention is described as follows:

[0044] See also Figure 1 and Figure 2 When the adaptive neck support of the present invention needs to be installed on a car seat, first use the hook portion 2-1 of the second hook 2 to hook the right headrest rod 3-2 of the car seat 3, and then forcefully pull the first hook 1 open to make it move outward relative to the connecting seat B along the direction V. When the first hook 1 is pulled away a sufficient distance, you can release your hand, so that the first hook 1 moves inward in the opposite direction of the direction V under the action of the restoring force F applied by the reset mechanism C, so that the hook portion 1-1 of the first hook 1 hooks the left headrest rod 3-1 of the car seat 3. Finally, under the action of the restoring force F applied by the reset mechanism C, the first hook 1 and the second hook 2 tightly hook the left headrest rod 3-1 and the right headrest rod 3-2 of the car seat 3, completing the installation and fixation of the adaptive neck support of the present invention on the car seat. At this time, the neck support body A can be used for supporting the neck of the occupant.

[0045] In addition, the order of hooking the right headrest rod 3-2 with the hook portion 2-1 of the second hook 2 and hooking the left headrest rod 3-1 with the hook portion 1-1 of the first hook 1 may also be reversed.

[0046] When it is necessary to remove the adaptive neck support of the present invention from the car seat, it is only necessary to operate in the reverse order of the above-mentioned installation process, and the hook portion 1-1 of the first hook 1 can be separated from the left headrest rod 3-1 of the car seat 3, and the hook portion 2-1 of the second hook 2 can be separated from the right headrest rod 3-2 of the car seat 3, so as to realize the removal of the adaptive neck support of the present invention from the car seat.

[0047] As for the case where the first hook 1 is located on the right side and the second hook 2 is located on the left side, the hook portion 2-1 of the second hook 2 can be used to hook the left headrest rod 3-1 of the car seat 3, and the hook portion 1-1 of the first hook 1 can be used to hook the right headrest rod 3-2 of the car seat 3, which will not be repeated here.

[0048] Therefore, the present invention has the advantage of convenient installation and disassembly.

[0049] Since the first hook 1 is pulled open to any distance within the designed stroke, the restoring force F applied by the reset mechanism C can be utilized to realize that the first hook 1 and the second hook 2 are tightly hooked onto the headrest rod of the automobile seat. This makes it possible for the adaptive neck brace of the present invention to be adaptively installed regardless of the spacing distance between the headrest rods of the automobile seat. Therefore, the present invention can be applicable to a variety of automobile seats with different spacing distances between the headrest rods, and has the advantage of good versatility.

[0050] Furthermore, the present invention does not need to add a dedicated mounting structure to the car seat, thus avoiding structural redundancy of the car seat.

[0051] In summary, the present invention has the advantages of convenient installation and disassembly and good versatility.

[0052] Embodiment 2

[0053] like Figures 3 to 6 As shown, based on the above-mentioned embodiment 1, this embodiment 2 also adopts the following preferred implementation manner:
