The embodiments described below with reference to the drawings are exemplary and intended to be used for explaining the present invention, and should not be construed as limiting the present invention.

Referring to fig. 1 to 6, a headrest assembly 100 for a vehicle seat according to an embodiment of the present invention is described, the headrest assembly 100 including a headrest 10 and side wings 20. Wherein the lateral wings 20 are detachably connected to the lateral sides of the headrest 10 by the link mechanisms 30. That is, the side wings 20 and the headrest 10 are relatively independent two parts, so that the side wings 20 having different functions can be configured according to different requirements of a user, thereby solving the problem that the conventional vehicle seat has a single function. In other words, the side wings 20 can be assembled with different functional modules, so that the variety thereof is diversified, and the headrest 10 only needs to reserve the assembling position of the side wings 20. Wherein each side wing 20 may have one of a heating module, a sound module, or a ventilation module disposed therein.

As shown in fig. 1, the lateral wings 20 may include a left lateral wing 20 located on the left side of the headrest 10 and a right lateral wing 20 located on the right side of the headrest 10, the left lateral wing 20 and the right lateral wing 20 may have the same or different shapes and structures, and the left lateral wing 20 and the right lateral wing 20 may have the same or different functions.

To facilitate assembly and disassembly of the side wings 20, as shown in fig. 2 in conjunction with fig. 3-6, the linkage mechanism 30 of the present embodiment includes: a first link 31 and a second link 32. Wherein one end of the first link 31 is connected to the side wing 20. The second link 32 is embedded in the headrest 10 and the second link 32 defines an insertion hole 322 open to the side of the headrest 10. Thus, when it is desired to assemble the wing 20, the other end of the first link 31 can be inserted into the insertion hole 322, i.e., the first link 31 is nested in the insertion hole 322 of the second link 32. When the side wings 20 are not needed, the first link 31 can be pulled out of the second link 32. In other words, the shoulder straps 20 are connected to the headrest 10 by simple insertion and removal, and the operation is simple and convenient.

In short, according to the headrest assembly 100 for the vehicle seat of the embodiment of the present invention, the side wings 20 are detachably connected to the sides of the headrest 10 through the link mechanisms 30, respectively, and the side wings 20 and the headrest 10 are easily assembled and disassembled, so that individual requirements of different users can be met.

In some optional embodiments of the present invention, as shown in fig. 4 and fig. 5, the link mechanism 30 further includes: and the limiting structure 33 is movably arranged on the second connecting rod 32 between the fixed position and the movable position of the first connecting rod 31. That is, the position of the limiting structure 33 relative to the second link 32 can be changed, so as to change the connection relationship between the second link 32 and the first link 31. When the position limiting structure 33 is located at the fixed position, the second link 32 is fixed relative to the first link 31, i.e. the lateral wing 20 is assembled on the headrest 10 and cannot be separated from the headrest 10; when the position-limiting structure 33 is located at the active position, the second link 32 is movable relative to the first link 31, i.e., the shoulder 20 can be detached from the headrest 10. In other words, the locking and separation of the side wings 20 to and from the headrest 10 is achieved by the position-limiting structures 33, so that on the one hand, the stability of the connection of the side wings 20 to the headrest 10 is ensured, and on the other hand, the separation of the side wings 20 from the headrest 10 is facilitated.

In an alternative embodiment, as shown in fig. 4 in combination with fig. 5 and 6, the open end of the second link 32 is provided with a stop flange 321, the stop flange 321 forms a guide groove 3211 with one open side and perpendicular to the axis of the insertion hole 322, and the limit structure 33 is movable in the guide groove 3211. That is, the open end of the second link 32 is provided with a guide groove 3211 for accommodating the position-limiting structure 33, and the guide groove 3211 can guide the movement of the position-limiting structure 33 between the fixed position and the movable position.

Specifically, the limit structure 33 includes: a body portion 331 and a snap projection 332. The body 331 forms a through hole 3311 communicating with the insertion hole 322. That is, the through hole 3311 of the body portion 331 is coaxially disposed with the insertion hole 322 of the second link 32. When the position-limiting structure 33 is disposed in the guiding groove 3211, the first connecting rod 31 can pass through the through hole 3311 and then enter the insertion hole 322. In this way, the locking protrusion 332 formed on the inner side of the body 331 and protruding out of the hole wall of the through hole 3311 can be locked into the locking groove of the first link 31, thereby limiting the axial displacement of the first link 31.

In an alternative example, as shown in fig. 4-6 in combination with fig. 3, the limiting structure 33 further includes: and an unlocking part 333, wherein the unlocking part 333 is disposed outside the body part 331, and at least a part of the unlocking part 333 is exposed outside the guide groove 3211. Thus, when the side wings 20 need to be detached, the side wings 20 can be easily detached from the headrest 10 by pressing the unlocking portions 333 to move the stopper structure 33 from the fixed position to the movable position.

In a further alternative example, as shown in fig. 4, a limiting groove 32111 is formed on a wall surface of the guide groove 3211, and a protrusion 3331 extending into the limiting groove 32111 is disposed on an outer edge of the unlocking portion 333. That is, the distance between one end and the other end of the position-limiting groove 32111 determines the moving range of the position-limiting structure 33, that is, the protrusion 3331 can move from one end (e.g., the upper end in fig. 4) of the position-limiting groove 32111 to the other end (e.g., the lower end in fig. 4) of the position-limiting groove 32111, and when the protrusion 3331 touches the end surface of the other end of the position-limiting groove 32111, i.e., when the position-limiting structure 33 has reached the moving position, the lateral wings 20 can be separated from the headrest 10.

In an alternative embodiment, a return spring 334 is further disposed in the guide slot 3211, and the return spring 334 stops against the outside of the body 331. When the clamping groove 311 of the first link 31 is matched with the clamping protrusion 332 of the limiting structure 33, the abutting force applied by the return spring 334 to the limiting structure 33 causes the limiting structure 33 to be positioned at a fixed position; after the first link 31 is separated from the insertion hole of the second link 32, the return spring 334 can drive the limiting structure 33 to return from the active position to the fixed position, so as to prepare for the next insertion of the first link 31.

In other embodiments of the present invention, a plurality of first connecting rods 31 are correspondingly connected to each of the side wings 20. Accordingly, the headrest 10 is provided with a plurality of second links 32 engaged with the first links 31, and the engagement between the plurality of first links 31 and the plurality of second links 32 improves the stability of connection between the shoulder 20 and the headrest 10.

It will be understood that when one of the first links 31 of the lateral wings 20 is locked to the corresponding second link 32, the other first links 31 will also be locked to the corresponding second link 32. That is, the first links 31 can be locked at the same time by one stopper 33, so that the assembly of the lateral wings 20 is simpler.

In other embodiments of the present invention, a positioning block (not shown) is disposed in the headrest 10, the positioning block defines a plurality of positioning holes, and one end of the first connecting rod 31 is inserted into the positioning holes. In this way, the first link 31 is inserted into the second link 32 more firmly, and the stability of the connection between the shoulder strap 20 and the headrest 10 is improved.

In other embodiments of the present invention, the lateral wing 20 is rotatable with respect to the first link 31, thereby changing the position of the lateral wing 20 with respect to the headrest 10. For example, the side wings 20 can rotate back and forth relative to the first links 31, and for example, the side wings 20 can rotate up and down relative to the first links 31, and for example, the side wings 20 can rotate back and forth and up and down relative to the first links 31, so that the position of the side wings 20 relative to the headrest 10 can be conveniently adjusted to meet different requirements.
