[0033] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0034] The following description, with reference to the accompanying drawings, describes a seat headrest 10, a seat device 100, and a vehicle according to embodiments of the present invention. The shape of the lower end of the seat headrest 10 is adjustable, which can meet the personalized needs of users and has good versatility.

[0035] like Figures 1-3 As shown, the seat headrest 10 according to an embodiment of the present utility model includes: a headrest body 1 and an airbag mechanism 2. The airbag mechanism 2 is disposed inside the headrest body 1 and is located at the lower end of the headrest body 1. The airbag mechanism 2 is used to support the user's neck. The airbag mechanism 2 has an inflated state and a deflated state. The airbag mechanism 2 can be switched to the inflated state or the deflated state. When the airbag mechanism 2 is in the inflated state, the airbag mechanism 2 can protrude to the front side and / or the lower side of the seat headrest 10.

[0036] The headrest 10 can be installed on the vehicle seat 20. When a user sits on the seat 20 equipped with the headrest 10, the user's neck can come into contact with the headrest 10, which can support the user's neck and improve user comfort. Furthermore, the headrest 10 has a certain degree of elasticity, which can act as a buffer in the event of a collision or rear-end collision, protecting the user's neck and reducing the risk of neck fracture.

[0037] The outermost part of the headrest body 1 is the headrest cover that comes into contact with the user. The headrest cover can be made of leather, fabric, or other materials. The headrest body 1 contains an airbag mechanism 2, such as... Figure 2 As shown in the front-to-back direction, the airbag mechanism 2 can protrude forward, allowing adjustment of the headrest 10's support position for the user's neck to achieve personalized support. Figure 1 and Figure 2 As shown in the vertical direction, the airbag mechanism 2 is located at the lower end of the headrest body 1. When the user sits on the seat 20 equipped with the seat headrest 10, the user's neck can come into contact with the airbag mechanism 2, and the airbag mechanism 2 can support the user's neck.

[0038] It is understandable that by placing the airbag mechanism 2 inside the headrest body 1, the headrest body 1 can cover the airbag mechanism 2, preventing the airbag mechanism 2 from directly contacting the user's neck. The headrest body 1 can have a certain degree of deformation capability; by inflating the airbag mechanism 2, the lower end of the headrest body 1 deforms, allowing the lower end of the headrest body 1 to contact the user's neck, thus achieving the effect of supporting the user's neck. Furthermore, the outer side of the headrest body 1 can be made of skin-friendly materials (i.e., the leather material, fabric material, etc. in the above embodiment) to improve user comfort. Moreover, by placing the airbag mechanism 2 inside the headrest body 1, the airbag mechanism 2 can be protected, reducing the risk of the airbag mechanism 2 being contaminated by debris and thus damaged.

[0039] The airbag mechanism 2 has an inflated state and a deflated state. The deflated state means that the airbag mechanism 2 is not filled with gas, and the inflated state means that the airbag mechanism 2 is partially filled with gas or reaches saturation. The airbag mechanism 2 can switch between the inflated state and the deflated state. When the airbag mechanism 2 is in the deflated state, the volume of the airbag mechanism 2 is relatively small, and the protrusion of the airbag mechanism 2 is small. When the airbag mechanism 2 is in the inflated state, compared with the deflated state, the volume of the airbag mechanism 2 is larger, and the protrusion of the airbag mechanism 2 is greater.

[0040] It is understandable that the volume of gas inflated by the airbag mechanism 2 is positively correlated with the degree of protrusion of the airbag mechanism 2. "Degree of protrusion" can be understood as the degree of volume change (expansion) of the airbag mechanism 2 when inflated compared to its deflated state. The larger the volume of gas inflated by the airbag mechanism 2, the greater the degree of protrusion. Specifically, this is reflected in the distance the airbag mechanism 2 protrudes forward and / or downward relative to the headrest body 1. The degree of protrusion of the airbag mechanism 2 is minimal when it is deflated. The seat headrest 10 has good versatility; the volume of gas inflated by the airbag mechanism 2 can be reasonably adjusted according to the user's needs, allowing the airbag mechanism 2 to have various personalized degrees of protrusion. This facilitates adjusting the seat headrest 10 to the user's desired position and angle, reliably supporting the user's neck to meet individual user needs and improve user comfort.

[0041] like Figure 1 and Figure 2 As shown in the front-back and up-down directions, when the airbag mechanism 2 is in the inflated state, the airbag mechanism 2 can protrude towards the front side of the seat headrest 10. The front side includes the directly front side and the lower front side, for example... Figure 2 As shown in direction A, or, the airbag mechanism 2 may protrude downwards towards the headrest 10, which may include the directly below side or the lower front side, for example... Figure 2 As shown in direction B, the airbag mechanism 2 may protrude towards the front and lower sides of the seat headrest 10. Specifically, this application will illustrate this by taking the example that the airbag mechanism 2 may protrude towards the front, lower front, and lower side of the seat headrest 10, for example... Figure 2 The directions A, B, and C shown are configured to make the headrest 10 a multi-directional adjustable neck support headrest. This configuration allows the airbag mechanism 2 to have multiple protrusion directions, resulting in various shapes for the lower end of the headrest 10. Different shapes can provide different support effects for the user's neck. Users can adjust the protrusion direction of the airbag mechanism 2 according to their actual needs to meet their personalized settings and improve the user experience.

[0042] In the above embodiment, by providing an airbag mechanism 2 inside the headrest body 1 that can be switched to an inflated or deflated state, the user can adjust the degree and direction of protrusion of the seat headrest 10 according to the user's needs, so as to adjust the shape of the lower end of the seat headrest 10 to support the user's neck. This setting can make the seat headrest 10 have better versatility, meet the user's personalized needs, and improve the user's comfort.

[0043] In some embodiments of this utility model, such as Figure 3 As shown, the airbag mechanism 2 includes multiple airbag structures 21, which are stacked sequentially along the height direction of the seat headrest 10.

[0044] The number of airbag structures 21 can be two, three, four, etc., along the height direction of the seat headrest 10. Figure 1 and Figure 2 As shown in the up-down direction, multiple airbag structures 21 can be stacked sequentially. Each airbag structure 21 has a protruding direction after inflation, and the user can adjust the degree of protrusion of each airbag structure 21. The degree and direction of protrusion of multiple airbag structures 21 can be superimposed so that the airbag mechanism 2 can form a variety of protruding shapes. Different shapes of airbag mechanisms 2 provide different support effects for the user's neck, so that the user can make personalized adjustments according to their needs. This kind of arrangement can make the seat headrest 10 suitable for different users, thereby improving the versatility of the seat headrest 10, enhancing its attractiveness and market competitiveness.

[0045] In some embodiments of this utility model, such as Figure 3 As shown, along the height direction of the seat headrest 10, in any two adjacent airbag structures 21, the front end of the upper airbag structure 21 protrudes beyond the front end of the lower airbag structure 21.

[0046] Among them, along Figure 3 In the vertical direction shown (the height direction of the seat headrest 10), in any two adjacent airbag structures 21, the front end of the upper airbag structure 21 can protrude beyond the front end of the lower airbag structure 21. The upper airbag structure 21 protrudes forward (including the front and lower front sides) relative to the lower airbag structure 21, and the lower airbag structure 21 protrudes downward (including the lower front and lower front sides) relative to the upper airbag structure 21. This arrangement allows adjacent airbag structures 21 to have more [missing information]. In terms of the protruding direction, the protruding directions of multiple airbag structures 21 can be superimposed to increase the protruding direction of the airbag mechanism 2. Different protruding directions correspond to different shapes of the lower end of the seat headrest 10, so that the lower end of the seat headrest 10 can have different shapes. By adjusting the protruding direction and degree of each airbag structure 21, the shape of the lower end of the seat headrest 10 can be adjusted, thereby adjusting the support effect of the seat headrest 10 on the user's neck, so that the seat headrest 10 can meet the personalized needs of different users and further improve the versatility of the seat headrest 10.

[0047] In some embodiments of this utility model, such as Figure 3 As shown, the rear end of the lower airbag structure 21 protrudes beyond the rear end of the upper airbag structure 21.

[0048] Among them, along Figure 3In the vertical direction shown (the height direction of the seat headrest 10), in any two adjacent airbag structures 21, the rear end of the lower airbag structure 21 can protrude beyond the rear end of the upper airbag structure 21. The upper airbag structure 21 protrudes forward (including the front and lower front sides) relative to the lower airbag structure 21, and the lower airbag structure 21 protrudes downward (including the lower front and lower front sides) relative to the upper airbag structure 21. This arrangement allows adjacent airbag structures 21 to have more protrusions. In terms of the direction of protrusion, the protrusion directions of multiple airbag structures 21 can be superimposed to increase the protrusion direction of the airbag mechanism 2. Different protrusion directions correspond to different shapes of the lower end of the seat headrest 10, so that the lower end of the seat headrest 10 can have different shapes. By adjusting the protrusion direction and degree of each airbag structure 21, the shape of the lower end of the seat headrest 10 can be adjusted, thereby adjusting the support effect of the seat headrest 10 on the user's neck, so that the seat headrest 10 can better meet the personalized needs of different users and further improve the versatility of the seat headrest 10.

[0049] In some embodiments of this utility model, such as Figure 3 As shown, all airbag structures 21 are constructed as sheet-like structures, and all airbag structures 21 protrude downwards from the seat headrest 10.

[0050] Among them, such as Figure 3 As shown, it should be noted that when the airbag structure 21 is in the deflated state, the airbag structure 21 is a sheet-like structure. Multiple airbag structures 21 can be constructed as sheet-like structures, and multiple airbag structures 21 can be constructed as polygons (rectangles, irregular quadrilaterals, etc.), circles, ellipses, etc. When the airbag structure 21 is in the deflated state, the volume of the airbag structure 21 is small. When the user does not need the support of the seat headrest 10, the airbag structure 21 can be switched to the deflated state to reduce the space occupied by the seat headrest 10 and meet the user's personalized needs.

[0051] Multiple airbag structures 21 can protrude downwards from the seat headrest 10, including directly below and in front of below, so that the protrusion direction of the airbag structure 21 in the deflated state is the same (or approximately the same) as the protrusion direction in the inflated state, so that when air is inflated into the airbag structure 21, the airbag structure 21 can expand in the required direction more quickly, thereby improving inflation efficiency.

[0052] In some embodiments of this utility model, any two adjacent airbag structures 21 are fixedly connected.

[0053] In this invention, any two adjacent airbag structures 21 can be fixedly connected. Alternatively, in some embodiments, they can be bonded together. Another embodiment allows for the integral molding of any two adjacent airbag structures 21. This arrangement fixes the relative position of adjacent airbag structures 21, reducing the risk of relative displacement during use that could alter their intended protrusion direction, thus ensuring the headrest 10 supports the user's neck in a pre-defined manner. Furthermore, this arrangement enhances the integration of the airbag mechanism 2, facilitating assembly.

[0054] In some embodiments of this utility model, such as Figure 3 As shown, the seat headrest 10 also includes: a mounting plate 3, which is fixed inside the headrest body 1 and is located above the airbag mechanism 2, and the airbag mechanism 2 is fixed to the mounting plate 3.

[0055] The mounting plate 3 can be fixed inside the headrest body 1 and can be located above the airbag mechanism 2. The shape of the mounting plate 3 is adapted to the shape of the airbag mechanism 2. The mounting plate 3 can be fixedly connected to the headrest body 1. In some embodiments of this utility model, the mounting plate 3 can be integrally formed with the headrest body 1. In some embodiments of this utility model, the airbag mechanism 2 can be snap-fitted to the headrest body 1. In some embodiments of this utility model, the airbag mechanism 2 can be adhesively connected to the mounting plate 3. In some embodiments of this utility model, the airbag mechanism 2 can be integrally formed with the mounting plate 3, which results in a reasonable structure and facilitates assembly.

[0056] In addition, during the process of switching the airbag mechanism 2 to the inflation state, the mounting plate 3 can reduce the amount of protrusion of the airbag mechanism 2 in the direction of the mounting plate 3, so that the airbag mechanism 2 expands in the direction away from the mounting plate 3 (the direction of the user's neck), thereby improving the inflation efficiency of the airbag mechanism 2, reducing inflation time, and improving the convenience of the seat headrest 10.

[0057] As some embodiments of this utility model, the mounting plate 3 can be constructed as a short-fiber felt board. The short-fiber felt board has good structural strength, is not easily deformed or broken, can protect the airbag mechanism 2, reduce the risk of damage to the airbag mechanism 2 from other components inside the seat headrest 10, and facilitates the assembly of the airbag mechanism 2 onto the headrest body 1 via the short-fiber felt board. The short-fiber felt board is mainly made of natural fibers (such as wool) or synthetic fibers, contains no harmful chemicals, and meets environmental protection requirements.

[0058] In some embodiments of this utility model, multiple airbag structures 21 are inflated or deflated independently of each other.

[0059] Each of the multiple airbag structures 21 can be set to inflate or deflate independently, allowing users to selectively inflate or deflate one or more of the multiple airbag structures 21 to adjust the degree and direction of protrusion of each airbag structure 21, thereby adjusting the degree and direction of protrusion of the airbag mechanism 2 to meet the user's personalized setting needs and improve the user's user experience.

[0060] In some embodiments of this utility model, such as Figure 2 As shown, the airbag mechanism 2 also includes: multiple air tubes 22, which are respectively connected to multiple airbag structures 21 to inflate or deflate the airbag structures 21 through the air tubes 22. The seat headrest 10 also includes a mounting rod 4, which is fixedly connected to the headrest body 1, and at least one air tube 22 passes through the mounting rod 4.

[0061] The multiple air tubes 22 can be connected to multiple airbag structures 21 respectively. Each airbag structure 21 can be connected to at least one air tube 22. The end of the air tube 22 away from the airbag mechanism 2 can be connected to an air pump. The air pump can inflate the corresponding airbag structure 21 or extract the gas from the airbag structure 21 through the air tube 22 to achieve the effect of inflating or deflating the airbag structure 21.

[0062] In some embodiments of this utility model, a controller, an inflation button, or a deflation button may be installed inside the vehicle. The inflation button or deflation button is communicatively connected to the controller, which is also communicatively connected to the air pump. The controller can control the start and stop of the air pump. When the user opens the inflation button or deflation button, the controller receives the inflation signal and deflation signal, and can control the air pump to start. The air pump can inflate gas into the corresponding airbag structure 21 or extract gas from the airbag structure 21 to achieve the effect of inflating or deflating the airbag structure 21. When the user closes the inflation button or deflation button, the controller can control the air pump to stop working.

[0063] like Figure 2 As shown, the mounting rod 4 can be fixedly connected to the headrest body 1. The mounting rod 4 can be welded to the headrest body 1 or snap-fitted to it. The mounting rod 4 can be constructed as a hollow tube, and at least one part of the air pipe 22 can be located inside the mounting rod 4. This arrangement can protect the air pipe 22 through the mounting rod 4, reduce the risk of damage caused by interference between the air pipe 22 and other components, facilitate assembly, and extend the service life of the air pipe 22. Each mounting rod 4 can have one air pipe 22, or multiple air pipes 22 can be inserted into each mounting rod 4. The number of air pipes 22 in each mounting rod 4 can be set according to design needs to improve the design flexibility of the seat headrest 10.

[0064] As some embodiments of this utility model, each airbag structure 21 can be connected to multiple air tubes 22 to improve the inflation and deflation efficiency of the airbag structure 21 and enhance the user's experience.

[0065] like Figures 4-7 As shown, the seat device 100 according to an embodiment of the present utility model includes: a seat 20 and a seat headrest 10. The seat 20 has a seat back 201, and the seat headrest 10 is the seat headrest 10 of the above embodiment. The seat headrest 10 is installed on the upper end of the seat back 201.

[0066] The headrest 10 and seat 20 can be configured as separate units. The headrest 10 can be installed on the upper part of the seat back 201 and can be screwed or snapped onto the seat back 201. The headrest 10 can also be detached from the seat back 201. When a user sits on the seat 100, their back can rest against the seat back 201, and their neck can rest against the headrest 10. An airbag mechanism 2, which can be switched between inflated and deflated states, is provided inside the headrest body 1, allowing the user to adjust the degree and direction of the headrest 10's protrusion according to their needs. This adjusts the shape of the lower end of the headrest 10 to support the user's neck. This design gives the headrest 10 better versatility, meeting individual user needs and improving user comfort.

[0067] The vehicle according to this utility model embodiment includes the seat device 100 of the above embodiment. By providing an airbag mechanism 2 inside the headrest body 1 that can be switched to an inflated or deflated state, the user can adjust the degree and direction of protrusion of the headrest 10 according to usage needs, thereby adjusting the shape of the lower end of the headrest 10 to support the user's neck. This configuration makes the headrest 10 more versatile, meeting the user's personalized needs and improving user comfort.
