[0027] As Figure 1 , 2 , 3, 4, 5 show an adaptive swing structure of a seat headrest of the present utility model, which includes a movable seat 10 and a mounting seat 20. The headrest 50 is mounted on the movable seat 10. A receiving groove 21 is provided on the mounting seat 20. The receiving groove 21 is recessed downward from the upper surface 201 of the mounting seat 20. Thus, a receiving space is formed on the mounting seat 20 through the receiving groove 21. Limiting end walls 211 are respectively formed on both sides of the receiving groove 21; a swing arm 11 extending backward is provided on the movable seat 10. The swing arm 11 is pivotally connected to the mounting seat 20 through a rotating shaft 23 extending in the height direction, so that the swing arm 11 can rotate relative to the mounting seat 20 around the rotating shaft 23, and then the movable seat 10 drives the headrest 50 to be able to swing left and right relative to the mounting seat 20. A support arm 12 is formed at the rear end of the swing arm 11. The support arm 12 extends into the middle position of the receiving groove 21, so that the support arm 12 is located between the two limiting end walls 211. A spring 30 is respectively provided between both sides of the support arm 12 and the two limiting end walls 211, that is, the spring 30 is located in the receiving groove 21, and one end of the spring 30 abuts against the limiting end wall 211 and the other end abuts against the support arm 12. Both springs 30 are placed in the receiving groove 21 in a compressed state. When the support arm 12 swings leftward in the mounting groove 22, the spring 30 on the left side of the support arm 12 is squeezed. After the left spring 30 is compressed and deformed, an elastic supporting force toward the right is applied to the support arm 12. When the support arm 12 swings rightward inside the mounting groove 22, the spring 30 on the right side of the support arm 12 is compressed and then an elastic supporting force toward the left is applied to the support arm 12.
[0028] As Figure 4 , 5 shown, during the use process, when the human head presses on the headrest 50 directly backward, the support arm 12 is in the middle position in the left-right direction of the receiving groove 21; when the human head presses on the headrest 50 at a position to the left of the headrest 50, the left side of the headrest 50 swings backward adaptively by a certain angle, so that the swing arm 11 swings adaptively around the rotating shaft 23. The spring 30 on the right side is compressed to provide an elastic supporting force to the support arm 12 until the elastic supporting force provided by the right spring 30 reaches equilibrium with the pressure of the headrest 50 received by the user's head, and then the adaptive swing of the headrest 50 is completed.
[0029] It should be noted that the accommodation space for accommodating the spring 30 and the support arm 12 in the present utility model is not limited to the accommodation groove 21 formed by the downward depression of the upper surface 201 of the mounting base 20 as described above. It can also be formed by other structures on the mounting base 20. In short, it can be used to place the spring 30 and the support arm 12 and form two opposite limiting end walls 211. As an elastic member, the spring 30 can also be replaced by other elastic members, such as an elastic rubber block, a metal spring piece, etc.
[0030] In the present utility model, the swing arm 11 is rotatably mounted on the mounting base 20 through a rotating shaft 23, and an elastic member is respectively arranged between the support arm 12 at the rear end of the swing arm 11 and the two limiting end walls 211. The two elastic members can respectively apply an elastic supporting force to the support arm 12 when being compressed, and this elastic supporting force can balance the offset pressure received by the headrest 50, so that the headrest 50 can automatically adapt to the deflection of the user's head. Thus, when the user is in different postures, it can provide good support for the user's head and neck, improving the comfort of the seat.
[0031] In a preferred embodiment, a downwardly recessed mounting groove 22 is further provided on the upper surface 201 of the mounting seat 20, the rear end of the mounting groove 22 is connected to the accommodating groove 21, and the front end extends to the front end surface 202 of the mounting seat 20, the swing arm 11 is embedded in the mounting groove 22, and the support arm 12 at the rear end of the swing arm 11 is located in the accommodating groove 21, the swing arm 11 swings in the mounting groove 22, and then the support arm 12 can swing in the accommodating groove 21, and the recessed mounting groove 22 is provided on the upper surface 201 of the mounting seat 20, so that the overall height dimension of the swing arm 11 and the mounting seat 20 after cooperation with each other is reduced, which is beneficial to reducing the space occupied by the entire structure in the height direction. In order to limit the rotation angle of the swing arm 11 and prevent the headrest 50 from swinging excessively, the above-mentioned mounting groove 22 includes two opposite side walls, and the side walls include a first section 221 and a second section 222. The first section 221 extends forward from the front edge of the accommodating groove 21, and the second section 222 extends from the front end of the first section 221 to the front end surface 202 of the mounting seat 20. The second section 222 is set to an inclined structure, which gradually inclines from the back to the front in a direction away from the middle of the mounting groove 22, so that the mounting groove 22 forms a structure that is wide in front and narrow in the back in the part located between the two second sections 222, that is, the width of the mounting groove 22 gradually decreases from front to back. The rotating shaft 23 is installed on the bottom surface of the mounting groove 22 and is located between the two side walls of the mounting groove 22. By setting the two second sections 222 to the above-mentioned inclined structure, the swing arm 11 can be within a predetermined angle range between the two second sections 222. The two limiting inclined surfaces 111 are matched with the two second sections 222 respectively. When the left side of the headrest 50 swings backward, the swing arm 11 swings left, and the limiting inclined surface 111 on the left abuts against the second section 222 on the left, limiting the maximum swing angle of the swing arm 11 to the left, and then limiting the maximum swing angle of the left side of the headrest 50 to the backward. When the right side of the headrest 50 swings backward, the second section 222 on the right is used to support the lower inclined surface 111 on the right, limiting the maximum swing angle of the swing arm 11 to the right, and then limiting the maximum swing angle of the right side of the headrest 50 to the backward, so as to avoid excessive swinging of the headrest 50 and prevent the user's head from sliding off the side of the headrest 50 when the headrest 50 swings too much.
[0032] In order to enable the spring 30 to stably provide elastic supporting force, a boss 212 is protruding from each limit end wall 211, and a boss 121 is protruding from both sides of the support arm 12. One end of the spring 30 is sleeved on the boss 212 and the other end is sleeved on the boss 121, thereby preventing the two ends of the spring 30 from slipping when cooperating with the limit end wall 211 and the support arm 12, so that the two ends of the spring 30 can stably abut the limit end wall 211 and the support arm 12.
[0033] An upper cover 24 is further provided on the upper surface 201 of the mounting base 20. The upper cover 24 is connected to the upper surface 201 by means of bolt connection, snap connection or other detachable fixing methods. The upper cover 24 is used to cover the upper part of the receiving groove 21 and the mounting groove 22, preventing the swing arm 11 and the spring 30 from disengaging from the mounting groove 22 and the receiving groove 21, and enabling the mounting base 20 and the movable base 10 to form a component and then be assembled with the headrest 50 and other components on the seat.
[0034] The mounting base 20 is connected to a fixed base 40. The mounting base 20 is mounted on the fixed base 40 in a manner that its position is adjustable in the front-rear direction. For example, guide rails extending in the front-rear direction can be provided on the fixed base 40, and the mounting base 20 is slidably mounted on the guide rails. After adjusting the mounting base 20 to the required position in the front-rear direction, a locking member is used to lock the mounting base 20 and the fixed base 40. A fixing plate 41 is connected to the fixed base 40 by means of bolt connection or other detachable fixing methods. The mounting base 20 is placed between the fixing plate 41 and the fixed base 40. An outer frame 42 is sleeved around the periphery of the fixed base 40 and the fixing plate 41. A plurality of snap fasteners 421 are provided on the outer frame 42, and the plurality of snap fasteners 421 are respectively snap-connected and fixed to the fixed base 40 and the fixing plate 41.
[0035] The seat of the present utility model includes the adaptive swing structure of the above-mentioned seat headrest, and the other structures of the seat are the same as those in the prior art and will not be described in detail here.
[0036] Finally, it should be noted that the above-mentioned embodiments are only optional embodiment modes of the present utility model, and the protection scope of the present utility model cannot be limited thereby. Any non-substantive changes and substitutions made by those skilled in the art on the basis of the present utility model fall within the protection scope required by the present utility model.
