DETAILED DESCRIPTION

[0051] The specific embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely intended to illustrate and explain the present disclosure, and are not intended to limit the present disclosure.

[0052] In the present disclosure, an XYZ coordinate system is set for the headrest, wherein the X direction is the front-rear direction of the headrest, the Y direction is the width direction of the headrest, and the Z direction is the height direction of the headrest. In addition, the W direction is set as the first direction. Unless otherwise specified, the orientation words such as "inner, outer" refer to the inner and outer relative to the outline of the component or structure itself. In addition, it should be noted that the terms such as "first, second" used herein are used to distinguish one element from another element, and do not have sequential and important meanings. In addition, in the description with reference to the drawings, the same reference signs in different drawings represent the same elements.

[0053] As Figures 1 to 16As shown, the first aspect of the present disclosure provides a headrest 1000, comprising a plurality of pillows 100, each pillow 100 having a pillow surface 100a facing forward along a front-rear direction, at least one pillow 100 being movable relative to the rest of the pillows 100, so that the pillow surface 100a of the at least one pillow 100 is movable relative to the pillow surfaces 100a of the rest of the pillows 100, so that an avoidance space is formed between the at least one pillow 100 and the rest of the pillows 100, when a passenger rests his head on the headrest 1000 and the back of the passenger's head has a protrusion, the protrusion of the back of the passenger's head can be located in the avoidance space, and the passenger rests his head on the pillow surfaces 100a of the rest of the pillows 100. This avoids the instability of the support of the headrest 1000 to the passenger's head caused by the extrusion of the protrusion of the back of the passenger's head, i.e. the headrest 1000 can provide stable and comfortable support to the passenger's head.

[0054] It should be understood that the headrest 1000 can also be suitable for different head shapes, for example, when the passenger's head does not have a protrusion at the back, the plurality of pillows 100 in the headrest 1000 can all be moved, to provide stable support to the passenger whose head does not have a protrusion at the back.

[0055] In addition, it should be noted that the movement distance of the pillow 100 that moves relative to the rest of the pillows 100 in the headrest 1000 can be set according to actual needs, which is not limited here.

[0056] In addition, the protrusion at the back of the passenger's head includes but is not limited to a ponytail hairstyle of the passenger's head or a decoration worn at the back of the passenger's head.

[0057] In some possible implementations, the headrest 1000 comprises a plurality of pillows 100, the plurality of pillows 100 are arranged side by side along the width direction of the headrest 1000, wherein the pillows 100 located on both sides of the width direction of the headrest 1000 can not be moved, and one or more pillows 100 between the pillows 100 on both sides of the headrest 1000 can be moved relative to the pillows 100 on both sides of the headrest 1000, so that the pillow surface 100a of the pillow 100 between the pillows 100 on both sides of the headrest 1000 is moved relative to the pillow surface 100a of the pillows 100 on both sides of the headrest 1000, to form an avoidance space to accommodate the protrusion at the back of the passenger's head. Of course, the headrest 1000 located on both sides of the width direction of the headrest 1000 can also be moved, which is not limited here.

[0058] In some possible embodiments, the headrest 1000 comprises a plurality of pillows 100 arranged side by side along a height direction of the headrest 1000, wherein the pillows 100 located at both sides of the headrest 1000 in the height direction are not movable, and one or more pillows 100 located between the pillows 100 at both sides of the headrest 1000 in the height direction are movable relative to the pillows 100 at both sides of the headrest 1000 in the height direction, so that the pillow surfaces 100a between the pillows 100 at both sides of the headrest 1000 in the height direction are moved relative to the pillow surfaces 100a of the pillows 100 at both sides of the headrest 1000 in the height direction, and an avoiding space for accommodating a protrusion at the back of a head of an occupant can be formed. Of course, the headrest 1000 located at both sides of the headrest 1000 in the height direction can also be movable, which is not limited herein.

[0059] In addition, it should be noted that the direction in which at least one pillow 100 in the headrest 1000 moves relative to the remaining pillows 100 can also be set according to actual needs. For example, the at least one pillow 100 in the headrest 1000 can be configured to be movable in a first direction along or obliquely to a front-rear direction of the headrest 1000.

[0060] When the headrest 1000 comprises a plurality of pillows 100 arranged along a width direction or a height direction of the headrest 1000, the pillows 100 located at both sides of the headrest 1000 in the width direction or the height direction can not be movable, and the pillows 100 located between the pillows 100 at both sides of the headrest 1000 in the width direction or the height direction can be movable relative to the pillows 100 at both sides of the headrest 1000 in the width direction or the height direction along a front-rear direction of the headrest 1000 or the first direction, and by moving the plurality of pillows 100 by different distances, the headrest 1000 can be suitable for occupants with different head shapes, and can provide more stable and comfortable support for occupants with different head shapes.

[0061] In some embodiments, at least one pillow 100 is movable relative to the remaining pillows 100, and the at least one pillow 100 movable relative to the remaining pillows 100 comprises a second pillow 20 having a second pillow surface 20a, and the remaining pillows 100 comprise a first pillow 10 having a first pillow surface 10a, the second pillow 20 is movably connected to the first pillow 10, so that the second pillow surface 20a is close to or away from the first pillow surface 10a. When the second pillow surface 20a is away from the first pillow surface 10a, an avoiding space for accommodating a protrusion at the back of a head of an occupant can be formed between the first pillow 10 and the second pillow 20; when the second pillow surface 20a is close to the first pillow surface 10a, the occupant without the protrusion at the back of the head can lean against.

[0062] In some embodiments, the first pillow body 10 has a first interference surface 10b, which is gradually inclined towards the second pillow body 20 from one end close to the first pillow surface 10a to the other end away from the first pillow surface 10a, so that the first interference surface 10b presses the second pillow body 20 when the second pillow body 20 moves rearward along the front-rear direction or the first direction of the headrest 1000.

[0063] In the above-mentioned embodiments, when the second pillow body 20 moves rearward along the front-rear direction or the first direction of the headrest 1000, the first pillow body 10 presses the second pillow body 20 through the first interference surface 10b, and the first pillow body 10 gives the second pillow body 20 a damping force through the first interference surface 10b, which can prevent the second pillow body 20 from moving excessively when the second pillow body 20 moves rearward along the front-rear direction or the first direction of the headrest 1000, i.e., avoid the second pillow body 20 moving to the bottom along the front-rear direction or the first direction of the headrest 1000 as soon as the second pillow body 20 is pushed, and can give the head of the occupant a certain support when the head of the occupant is resting on the second pillow body 20 at any position of the moving path of the second pillow body 20.

[0064] In some embodiments, as shown in Figure 1 , Figure 2 and Figure 13 , the first pillow body 10 is provided with an avoiding groove 30 penetrating the first pillow surface 10a, the second pillow body 20 is movably arranged in the avoiding groove 30 along the front-rear direction or the first direction of the headrest 1000, and the inner wall surface of at least part of the avoiding groove 30 forms the first interference surface 10b.

[0065] In the above-mentioned embodiments, the second pillow body 20 can move in the avoiding groove 30 along the front-rear direction or the first direction of the headrest 1000, so that the second pillow surface 20a is away from the first pillow surface 10a, and an avoiding space is formed in the avoiding groove 30, and when the occupant's head has a protrusion at the back side, the occupant's head can rest on the first pillow surface 10a, and the protrusion can be located in the avoiding space, so that the protrusion of the occupant's head can be avoided from being pressed, so that the headrest 1000 can provide stable and comfortable support to the occupant.

[0066] In addition, the inner wall surface of at least part of the avoiding groove 30 can form the first interference surface 10b, and when the second pillow body 20 moves rearward along the front-rear direction or the first direction in the avoiding groove 30, the inner wall surface of at least part of the avoiding groove 30 forming the first interference surface 10b can press the second pillow body 20, so that the first pillow body 10 can give the second pillow body 20 a damping force through the inner wall surface of the avoiding groove 30.

[0067] In some specific embodiments, as shown in Figure 5 and Figure 13As shown, the top surface of the avoiding groove 30 can be configured as the first interference surface 10b, which is gradually inclined towards the second pillow body 20 from one end close to the first pillow surface 10a to the other end away from the first pillow surface 10a, and the second pillow body 20 moves in the first direction. During the movement of the second pillow body 20 towards the rear side of the headrest 1000 in the first direction, the top surface of the avoiding groove 30 will interfere with the movement of the second pillow body 20. During the movement of the second pillow body 20, the first pillow body 10 gives the second pillow body 20 a damping force through the top surface of the avoiding groove 30.

[0068] In some embodiments, the first pillow surface 10a of the first pillow body 10 can be arbitrarily set according to actual needs. For example, as shown in Figure 14 As shown, the first pillow surface 10a includes a first area surface 10a1 and a second area surface 10a2 extending in the height direction of the headrest 1000, and a third area surface 10a3 arranged in the width direction of the headrest 1000, the first area surface 10a1 and the second area surface 10a2 are arranged in the width direction of the headrest 1000, and the third area surface 10a3 is connected to the first area surface 10a1 and the second area surface 10a2, so that the first area surface 10a1, the second area surface 10a2 and the third area surface 10a3 form the slot of the avoiding groove 30. Through the above setting, when the head of the occupant is on the headrest 1000, it is convenient to make the protrusions on the rear side of the head located in the avoiding space formed between the first pillow body 10 and the second pillow body 20, and it is also convenient to provide stable and comfortable support for the head of the occupant. When the headrest 1000 is applied to the seat of the vehicle, the head of the occupant can be at least on the third area surface 10a3, and when the speed of the vehicle suddenly changes or a collision occurs, the headrest 1000 can ensure that the head of the occupant is stably supported, thereby ensuring that the headrest 1000 has high safety performance.

[0069] It should be noted that the first pillow surface 10a of the first pillow body 10 of the headrest 1000 can also be configured in different shapes, which is not limited here.

[0070] In some embodiments, the first pillow body 10 and the second pillow body 20 can be configured in any appropriate form. For example, as shown in Figure 1 and Figure 2 As shown, the first pillow body 10 includes a first pillow pad 11 and a cooperating part 12, the first pillow pad 11 wraps part of the cooperating part 12, the first pillow surface 10a is formed on the first pillow pad 11, and the avoiding groove 30 is arranged on the first pillow pad 11. In addition, the second pillow body 20 includes a second pillow pad 21 and a support assembly 22, the second pillow pad 21 wraps part of the support assembly 22, and the second pillow surface 20a is formed on the second pillow pad 21. The support assembly 22 is movably connected to the cooperating part 12, so that the second pillow body 20 moves relative to the first pillow body 10.

[0071] In the above embodiments, the first pillow 11 can be made of polyurethane foaming and a cover wrapping the foaming, and the second pillow 21 can also be made of polyurethane foaming and a cover wrapping the foaming, which will not be described herein.

[0072] In some embodiments, as shown in Figure 4 、 Figure 5 and Figure 12 , the second pillow 21 is provided with a first limiting part 211, and the support assembly 22 is provided with a second limiting part 2212a, the first limiting part 211 and the second limiting part 2212a cooperate to limit the overturning of the second pillow 21 relative to the support assembly 22, so as to ensure the stability of the connection between the second pillow 21 and the support assembly 22.

[0073] In the above embodiments, the first limiting part 211 and the second limiting part 2212a can be configured in any appropriate form. For example, the first limiting part 211 can include a limiting groove, and the second limiting part 2212a can include a limiting protrusion inserted into the limiting groove.

[0074] In other possible embodiments, the first limiting part 211 can include a limiting protrusion, and the second limiting part 2212a can include a limiting groove for the limiting protrusion to be inserted into.

[0075] In some specific embodiments, as shown in Figure 2 、 Figure 3 、 Figure 6 and Figure 7 , the fitting part 12 is provided with a sliding groove 121 extending along the front-rear direction or the first direction of the headrest 1000, and the support assembly 22 further includes a support part 221 and a connecting assembly 222, the support part 221 being slidably connected to the sliding groove 121 through the connecting assembly 222.

[0076] In the above embodiments, the support part 221 is wrapped in the second pillow 21, the connecting assembly 222 is provided in the second pillow 21, and the support part 221 is slidably connected to the sliding groove 121 through the connecting assembly 222.

[0077] In some embodiments, the connecting assembly 222 can be provided in any appropriate form. For example, as shown in Figure 2 、 Figure 3 and Figure 9As shown, the connecting assembly 222 can include a connecting shaft 2221 and an elastic connecting member 2222, one end of the connecting shaft 2221 is slidingly connected to the sliding groove 121, and the other end of the connecting shaft 2221 is connected to the support member 221 through the elastic member, so that the connecting shaft 2221 abuts against the inner wall of the sliding groove 121 along the axis direction of the connecting shaft 2221, which can prevent the connecting shaft 2221 from being pulled out of the sliding groove 121 when the connecting shaft 2221 moves along the front-rear direction or the first direction of the headrest 1000, so that the connecting shaft 2221 can stably slide in the sliding groove 121.

[0078] In addition, the connecting shaft 2221 is connected to the support member 221 through the elastic connecting member 2222, which can also facilitate the installation of the connecting shaft 2221 in the sliding groove 121. When installing the connecting shaft 2221 in the sliding groove 121, the connecting shaft 2221 is first moved towards the support member 221 to compress the elastic connecting member 2222, and then when the connecting shaft 2221 is installed in the sliding groove 121, the elastic force of the elastic connecting member 2222 presses the connecting shaft 2221 against the inner wall of the sliding groove 121 to complete the installation.

[0079] In the above embodiments, the elastic connecting member 2222 can be arbitrarily configured according to actual needs. For example, the elastic connecting member 2222 can be configured as a spring 22220 or an elastic rubber member, etc.
