Description
Technical Field
[0001] This utility model relates to the field of automotive seat headrest technology, specifically to an automotive seat head support structure with an integrated neck support and headrest design. Background Technology
[0002] Car seat headrests are one of the important components of a car, primarily used to support the occupants' heads and ensure their comfort. To further enhance passenger comfort, a neck brace is usually installed at the lower end of the headrest to support the occupant's neck.
[0003] In the existing technology, in order to meet the needs of occupants of different body types, headrests are mostly designed as four-way headrests, that is, they have both up-and-down and forward-and-back adjustment functions. However, due to the differences in the body shape of occupants, some occupants have a large distance between the back of their neck and the back of their head. A single headrest adjustment cannot meet the needs of such occupants for neck support. Furthermore, the four-way headrest is limited by the overall structure and assembly space, and cannot further meet the installation requirements of the neck support adjustment mechanism. Utility Model Content
[0004] In view of this, the present invention provides a car seat head support structure with an integrated neck support and headrest design, which can ensure four-way adjustment of the headrest while also having the function of neck support adjustment.
[0005] To achieve the above objectives, the technical solution of this utility model is as follows:
[0006] A car seat head support structure with an integrated neck brace and headrest includes a headrest rod, on which a headrest is mounted. The headrest has a support base plate, which is movable up and down and back and forth relative to the headrest rod. The characteristic feature is that the support base plate has a downwardly extending lower mounting structure, on which a neck brace is integrated, and the neck brace is movable back and forth relative to the lower mounting structure.
[0007] With the above structure, the neck support integrated into the lower mounting structure enables the seat head support structure to have both a four-way headrest and a neck support for front and rear adjustment. In addition to its basic front and rear adjustment function, the neck support can move forward synchronously when the support base moves forward relative to the headrest rod, which significantly improves the movement range of the neck support. Similarly, when the headrest moves upward, the neck support can also have a height adjustment function. The integrated design also makes the overall structure more compact.
[0008] Preferably, the headrest has a base disposed at the upper end of the headrest rod, and a support base plate disposed at the front end of the base. A first driving assembly and a second driving assembly are disposed within the base. The first driving assembly drives the base to move vertically relative to the headrest rod, and the second driving assembly drives the support base plate to move forward and backward relative to the base. This structure enables both forward and backward movement and vertical movement of the headrest.
[0009] Preferably, the lower mounting structure has a mounting groove, and a third drive component that is connected to the neck support is disposed in the mounting groove. The third drive component is used to drive the neck support to move back and forth relative to the support base plate. With the above structure, the neck support can be adjusted back and forth and can be integrated into a four-way headrest.
[0010] Preferably, the support base has a horizontally extending rearward support section, and the base has a second through hole extending in the front-rear direction, with the support section movably passing through the second through hole; the second drive assembly includes a second motor disposed inside the base and a second rotating rod poweredly connected to the second motor, a second gear fixedly mounted at the end of the second rotating rod, and a second rack fixedly mounted at the top of the support section, with the second gear meshing with the second rack. With this structure, the headrest and neck brace can be adjusted forward and backward as a whole.
[0011] Preferably, the base has a first through hole extending vertically on both its left and right sides, and the upper end of the headrest rod passes through the first through hole; the first drive assembly includes a first motor disposed inside the base and a first rotating rod powered by the first motor, a first gear fixedly mounted at the end of the first rotating rod, and a first rack extending vertically at the rear end of the headrest rod, the first gear meshing with the first rack. With this structure, the headrest and neck support can be adjusted vertically as a whole.
[0012] Preferably, the third driving component is an airbag. The rear end of the airbag is fixedly connected to the inner side of the mounting groove, the front end of the airbag is connected to the neck brace, and the distal end of the airbag is connected to an air supply component. The air supply component is used to inflate and deflate the airbag. When the airbag is inflated, it can push the neck brace forward; when the airbag is deflated, it can pull the neck brace backward. With the above structure, the neck brace can be adjusted forward and backward independently by inflating and deflating the airbag, thereby meeting the usage needs of people with different body types.
[0013] Preferably, the lower end of the support base plate is provided with third through holes on both the left and right sides of the mounting groove, and the neck brace has a rearwardly extending support portion that passes through the third through hole. This structure guides the forward and backward movement of the neck brace and makes its movement more stable.
[0014] Preferably, a rearwardly extending connecting portion is provided between the two support portions, the connecting portion being used for connection with the airbag. This structure facilitates connection with the airbag.
[0015] Preferably, the neck brace has a massage air bag at its front end, the connecting part is a hollow structure, and an air tube is connected to the rear end of the massage air bag. The air tube passes through the connecting part and is connected to the air supply component through the rear end of the connecting part. This structure allows for neck massage of the occupant, ensuring passenger comfort.
[0016] Preferably, the rear end of the support portion is provided with a limiting protrusion, which protrudes outward from the side of the support portion, and the rear end of the limiting protrusion is provided with a guide slope. With the above structure, the limiting protrusion can limit the movement of the neck brace, preventing the support portion from falling out of the third through hole, and the guide slope facilitates the installation of the support portion into the third through hole.
[0017] Compared with the prior art, the beneficial effects of this utility model are:
[0018] 1. The car seat head support structure with integrated neck support and headrest design provided by this utility model has both headrest and neck support position adjustment functions. The headrest part can be adjusted forward and backward and in height, while the neck support part can be adjusted independently forward and backward.
[0019] 2. By providing a downwardly extending mounting structure at the bottom of the support base and mounting the neck brace on this structure, the neck brace, in addition to its independent front-to-back adjustment function, can also move synchronously forward-to-back and up-and-down with the headrest during four-way adjustment. This design not only provides the neck brace with height adjustment, but also allows the front-to-back adjustment of the neck brace to be combined with the front-to-back adjustment of the headrest, thereby significantly increasing the displacement range of the neck brace's front-to-back adjustment. Therefore, the head support structure provided by this utility model has more flexible adjustment options and can provide comfortable support for users with different body types.
[0020] 3. Using a single support base plate as the mounting base for the headrest and neck support components offers technical advantages such as high integration, compact product structure, ease of assembly, and good appearance quality. Attached Figure Description

[0031] The present invention will be further described below with reference to the embodiments and accompanying drawings.
[0032] like Figures 1 to 6 As shown, a car seat head support structure with an integrated neck support and headrest design includes a headrest rod 8. The lower end of the headrest rod 8 is fixedly installed on the top of the car seat back, and a headrest 3 is mounted on the upper end of the headrest rod 8. The headrest 3 has a support base plate 2, which can move up and down and back and forth relative to the headrest rod 8. The support base plate 2 has a downwardly extending lower mounting structure 2a, on which a neck support 4 is integrated. The neck support 4 can move back and forth relative to the lower mounting structure 2a.
[0033] This design, with the neck support 4 integrated on the lower mounting structure 2a, allows the seat head support structure to function as both a four-way headrest and a neck support that can be adjusted forward and backward. In addition to its basic forward and backward adjustment function, the neck support 4 can move forward synchronously when the support base plate 2 moves forward relative to the headrest rod 8, significantly increasing the travel of the neck support 4. Similarly, when the headrest 3 moves upward, the neck support 4 can also have a height adjustment function. The integrated design also makes the overall structure more compact and aesthetically pleasing.
[0034] like Figure 2 and Figure 5 As shown, the headrest 3 has a base 1, which is mounted on the upper end of the headrest rod 8. A support base plate 2 is mounted on the front end of the base 1. A first drive assembly 5 and a second drive assembly 6 are fixedly installed inside the middle of the base 1. The first drive assembly 5 is used to drive the base 1 to move up and down relative to the headrest rod 8, and the second drive assembly 6 is used to drive the support base plate 2 to move back and forth relative to the base 1. This design enables the headrest 3 to be adjusted up and down and back and forth.
[0035] In this embodiment, a mounting groove 2e is formed on the lower mounting structure 2a, extending towards the side where the base 1 is located. A mounting cavity adapted to the mounting groove 2e is formed at the lower middle part of the base 1. A third drive assembly 7, which is poweredly connected to the neck support 4, is installed inside the mounting groove 2e. The third drive assembly 7 is used to drive the neck support 4 to move back and forth relative to the support base plate 2. This design enables the neck support 4 to adjust back and forth and can be integrated into the four-way headrest, resulting in a more compact overall structure.
[0036] like Figure 3 , Figure 5 and Figure 9 As shown, the base 1 has first through holes 1a formed on its left and right sides, extending vertically. The upper end of the headrest rod 8 passes through the first through holes 1a. The first drive assembly 5 includes a first motor 5a fixedly installed on the inner side of the middle of the base 1 and a first rotating rod 5b powered by the first motor 5a. A first gear 5c is fixedly installed at the end of the first rotating rod 5b. A first rack 8a extending vertically is formed at the rear end of the headrest rod 8. The first gear 5c meshes with the first rack 8a. By driving the first motor 5a to rotate the first rotating rod 5b, the first gear 5c can move on the first rack 8a, thereby allowing the base 1 to move up and down relative to the headrest rod 8, thus realizing the overall up and down movement adjustment of the headrest 3 and neck support 4.
[0037] like Figure 3 , Figure 5 and Figure 6As shown, four horizontally extending rearward support segments 2b are formed on the support substrate 2, and the four support segments 2b are evenly distributed at the four corners of the support substrate 2. Four through holes 1b extending in the front-rear direction are formed on the base 1. Each support segment 2b is movably installed within each of the two through holes 1b. The second drive assembly 6 includes a second motor 6a disposed inside the base 1 and a second rotating rod 6b powered by the second motor 6a. A second gear 6c is fixedly installed at the end of the second rotating rod 6b. In this embodiment, a second rack 2c extending in the length direction is formed on the top of the two support segments 2b at the upper end of the support substrate 2. The second gear 6c meshes with the second rack 2c. When the second motor 6a drives the second rotating rod 6b to rotate, the second gear 6c can move on the second rack 2c, thereby enabling the headrest 3 to move in the front-rear direction.
[0038] In this embodiment, the first rotating rod 5b and the second rotating rod 6b are arranged in parallel and are located in the same vertical plane. This design allows the first driving component 5 and the second driving component 6 to be installed more tightly, thereby making the overall head support structure more compact and facilitating the installation of the third driving component 7. This enables the head support structure to have both four-way adjustment of the headrest 3 and individual adjustment of the neck brace 4.
[0039] like Figure 3 As shown, in this embodiment, the third drive component 7 is an airbag. The rear end of the airbag is fixedly installed inside the mounting groove 2e by bolts, and the front end of the airbag is fixedly connected to the neck support 4. An air supply component is also connected to the far end of the airbag. To ensure the overall size of the headrest assembly, the air supply component is not set on the base 1. Since the air supply component is a relatively mature existing technology, it is not shown in this embodiment, and its structure will not be described in detail. The air supply component is connected to the airbag by an air passage. The air supply component is used to inflate and deflate the airbag. When the airbag is inflated, it can push the neck support 4 forward. When the airbag is deflated, it can pull the neck support 4 backward. With this design, the neck support 4 can be adjusted back and forth independently relative to the headrest 3 by inflating and deflating the airbag, thereby meeting the needs of passengers of different body types for the neck support 4.
[0040] Furthermore, such as Figure 2 , Figure 4 and Figure 7As shown, third through holes 2d are provided on both the left and right sides of the mounting groove 2e at the lower end of the support base plate 2. The neck support 4 has a rearwardly extending support portion 4a, which passes through the third through hole 2d. A limiting protrusion 4a1 is formed at the rear end of the support portion 4a, protruding outward from the side of the support portion 4a. A guide slope 4a2 is also formed at the rear end of the limiting protrusion 4a1. With this design, the support portion 4a makes the neck support 4 move back and forth more stably. The guide slope 4a2 facilitates the support portion 4a to pass through the third through hole 2d, and the limiting protrusion 4a1 limits the forward movement of the neck support 4, preventing the neck support 4 from extending too far forward and separating from the support base plate 2.
[0041] For example Figure 7 and Figure 8 As shown, a rearwardly extending connecting portion 4b is formed between the two supporting portions 4a. The rear end of the connecting portion 4b is used to connect to the front end of the airbag. In this embodiment, the front end of the neck brace 4 has a massage airbag 4c. The connecting portion 4b is a hollow structure, and the rear end of the massage airbag 4c is connected to an air tube 4d. The air tube 4d passes through the interior of the connecting portion 4b and is connected to the air supply component through the rear end of the connecting portion 4b. With this design, the massage airbag 4c can massage the occupant's neck, providing a more comfortable riding experience.
[0042] like Figure 10 As shown, in this embodiment, a cover plate 9 is provided between the neck brace 4 and the support base plate 2. The cover plate 9 can block and limit the front end of the mounting groove 2e to prevent the neck brace 4 from separating from the support base plate 2 due to excessive inflation of the airbag.
[0043] Finally, it should be noted that the above description is merely a preferred embodiment of the present utility model. Those skilled in the art, under the guidance of the present utility model, can make various similar representations without departing from the spirit and claims of the present utility model, and such modifications all fall within the protection scope of the present utility model.
