Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, and in particular to a headrest and a car seat. Background Technology

[0002] Seat headrests are a type of driving comfort and safety equipment. Currently, the materials used in seat headrests are generally ordinary foam. However, because ordinary foam is mostly closed-cell or low-density, it rebounds quickly after being compressed, lacks slow rebound characteristics, has poor support distribution, and is prone to fatigue and deformation, resulting in a short lifespan for the headrest. In addition, existing seat headrests are not designed according to the curve of the human head and neck, which can easily cause muscle soreness after prolonged use. Utility Model Content

[0003] In order to solve the above problems, the purpose of this utility model is to provide a seat headrest.

[0004] This utility model is achieved through the following technical solution:

[0005] A seat headrest includes a pillow body having a memory foam layer, the pillow body comprising:

[0006] The main support area includes a head support portion and a neck support portion extending from the head support portion to one end of the pillow body. The surface of the head support portion is formed with a curved surface that conforms to the characteristics of the human head, and the surface of the neck support portion is formed with a curved surface that conforms to the characteristics of the human neck.

[0007] A secondary support area extends outward from the main support area, and the height of the main support area is higher than that of the secondary support area.

[0008] In one possible implementation, the main support region is a deformable structure, which can be deformed into a shape that adapts to the ballast.

[0009] In one possible implementation, the main support area protrudes from the surface of the secondary support area, and the protrusion height of the main support area from the surface of the secondary support area is 40-50 mm.

[0010] In one possible implementation, the curvature of the surface formed by the head support portion along the width direction of the pillow body is greater than the curvature of the surface formed by the neck support portion along the width direction of the pillow body.

[0011] In one possible implementation, the pillow body further includes a transition zone, through which the neck support portion and the secondary support zone are connected, and the surface of the transition zone is arc-shaped.

[0012] In one possible implementation, the secondary support area includes a cervical spine support portion formed by inward contraction from one end of the pillow body, the cervical spine support portion being connected to the transition area to form an inclined surface.

[0013] In one possible implementation, the cervical spine support is trapezoidal in shape.

[0014] In one possible implementation, the pillow body also has a breathable layer located on the surface of the memory foam layer.

[0015] In one possible implementation, the density of the memory foam layer is 40–150 kg / m³. 3 .

[0016] In one possible implementation, the rebound time of the memory foam layer is 5 to 6 seconds.

[0017] This utility model also provides a car seat, including a seat body and a headrest as described in the above embodiments.

[0018] This utility model has the following beneficial effects:

[0019] This utility model discloses a headrest for seats, comprising a pillow body with a memory foam layer. By incorporating a memory foam layer within the pillow, the headrest exhibits slow rebound characteristics, allowing for even pressure distribution under pressure and improving the headrest's support force dispersion. This also avoids the problem of short lifespan caused by fatigue and deformation in headrests made with ordinary foam materials. The pillow body includes a main support area and a secondary support area. The main support area has a head support portion and a neck support portion extending from one end of the pillow body. The surface of the head support portion is formed with a curved surface conforming to the characteristics of the human head, and the surface of the neck support portion is formed with a curved surface conforming to the characteristics of the human neck. The secondary support area extends outwards from the main support area, with the main support area being higher than the secondary support area. This allows the headrest to better conform to the curve of the human head and neck, improving comfort and preventing muscle soreness after prolonged use. Attached Figure Description

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0026] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this utility model are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of the utility model described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion. For example, a process, method, apparatus, product, or device that includes a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or devices.

[0027] The embodiments are described below with reference to the accompanying drawings, which do not limit the disclosure described in the claims.

[0028] The following description, in conjunction with the accompanying drawings, describes a seat headrest provided by an embodiment of the present invention, including a pillow body 1 with a memory foam layer, such as... Figure 1 As shown, the pillow body 1 includes:

[0029] The main support area 11 is provided with a head support part 111 and a neck support part 112 extending from the head support part 111 to one end of the pillow body 1. The surface of the head support part 111 is formed with a curved surface that conforms to the characteristics of the human head, and the surface of the neck support part 112 is formed with a curved surface that conforms to the characteristics of the human neck.

[0030] The secondary support area 12 is formed by extending outwards from the main support area 11. The height of the main support area 11 is higher than the height of the secondary support area 12.

[0031] The headrest of this invention has a slow rebound characteristic, which allows the headrest to evenly distribute pressure when compressed, improving the support force distribution of the headrest. At the same time, it avoids the problem of short service life caused by fatigue deformation of headrests made of ordinary foam. Furthermore, the headrest of this invention can better conform to the curve of the human head and neck, improving human comfort and avoiding muscle soreness after prolonged use.

[0032] Specifically, the shape of the pillow body 1 can be rectangular, square, circular or elliptical, etc., and the shape of the main support area 11 can be rectangular, square, circular or elliptical, etc., without specific limitation in this application.

[0033] In some embodiments, the density of the memory foam layer is 40–150 kg / m³. 3 In the event of a rear-end collision, high-density memory foam can quickly absorb the impact force on the head. By limiting the density of the memory foam layers, the headrest's impact resistance can be improved, further protecting the head and neck. It also enhances the headrest's support, preventing it from collapsing or deforming over long-term use and extending its lifespan. Preferably, the density of the memory foam layers is 80–110 kg / m³. 3 Preferably, the density of the memory foam layer is 90 kg / m³. 3 .

[0034] In some embodiments, the rebound time of the memory foam layer is 5 to 6 seconds. Too short a rebound time will result in poor impact resistance of the headrest, while too long a rebound time will cause it to lose its support performance during a secondary impact, posing a risk of injury. Limiting the rebound time of the memory foam layer avoids the above problems.

[0035] In some embodiments, the main support region 11 is a deformable structure, capable of deforming to adapt to the shape of the ballast. Since the head and neck curves of people of different body types vary, this invention, by setting the main support region 11 as a deformable structure, can adapt to the head and neck curves of people of different body types.

[0036] In some embodiments, the main support area 11 protrudes from the surface of the secondary support area 12, and the protrusion height of the main support area 11 from the surface of the secondary support area 12 is 40-50 mm. By limiting this protrusion height, the problem of poor user comfort and safety caused by the main support area 11 being too high or too low is avoided. Preferably, the protrusion height is 45 mm.

[0037] In some embodiments, such as Figure 2 As shown, the curvature of the surface formed by the head support 111 along the width direction of the pillow body 1 is greater than the curvature of the surface formed by the neck support 112 along the width direction of the pillow body 1. This arrangement makes the design of the seat headrest more conform to the curves of the human head and neck, further improving the user's comfort.

[0038] In some embodiments, such as Figure 1 As shown, the pillow body 1 also includes a transition zone 13. The neck support portion 112 and the secondary support portion 12 are connected through the transition zone 13, and the surface of the transition zone 13 is arc-shaped. The neck support portion 112 supports the neck of the human body, and the secondary support portion 12 supports the cervical spine below the neck. The arc-shaped transition zone 13 connects the neck support portion and the secondary support portion 12, thereby allowing the pillow to better conform to the curve between the neck and the cervical spine, preventing a small part of the neck from being suspended in the air, and playing a role in protecting the neck and cervical spine.

[0039] Specifically, the transition zone 13 is arranged around the main support zone 11, and the main support zone 11 and the secondary support zone 12 are connected through the transition zone 13.

[0040] In some embodiments, the transition region 13 is annular in shape.

[0041] In some embodiments, such as Figure 1 As shown, the secondary support area 12 includes a cervical spine support portion 121 formed by inward contraction from one end of the pillow body 1. The cervical spine support portion 121 is connected to the transition area 13 to form an inclined surface. The cervical spine support portion 121 is used to support the cervical spine of the human body. By connecting the cervical spine support portion 121 to the transition area 13 to form an inclined surface, the headrest further conforms to the curve between the cervical spine and the neck, reducing cervical spine fatigue caused by long-term sitting, reducing the risk of cervical spondylosis, and improving driving comfort.

[0042] Specifically, a first arc-shaped structure 124 and a second arc-shaped structure 125 are respectively provided on the side edge of the cervical spine support 121 away from the main support area 11.

[0043] In some embodiments, such as Figure 1 As shown, the cervical spine support 121 is trapezoidal in shape. By setting the shape of the cervical spine support 121 to trapezoidal, it can be better adapted to car seats and is easier to install.

[0044] In some embodiments, such as Figure 1 As shown, the secondary support area 12 includes a first shoulder support part 122 and a second shoulder support part 123. The first shoulder support part 122 and the second shoulder support part 123 are arranged opposite to each other on both sides of the main support area 11. The first shoulder support area forms a slope transition along the width direction of the pillow, and the second shoulder support part 123 forms a slope transition along the width direction of the pillow.

[0045] Specifically, the edge of the first shoulder support 122 away from the cervical spine support 121 is provided with a third arc-shaped structure 126, and the edge of the second shoulder support 123 away from the cervical spine support 121 is provided with a fourth arc-shaped structure 127.

[0046] In some embodiments, the side of the first shoulder support 122 near the cervical spine support 121 is connected to the cervical spine support 121 to form an arc, and the side of the second shoulder support 123 near the cervical spine support 121 is connected to the cervical spine support 121 to form an arc.

[0047] In some embodiments, the pillow body 1 also has a breathable layer located on the surface of the memory foam layer. By providing a breathable layer on the surface of the memory foam layer, the feeling of stuffiness can be reduced.

[0048] Specifically, the breathable layer can be made of breathable fabrics such as polyester and spandex, or other breathable fabrics. This application does not specifically limit the material of the breathable layer.

[0049] like Figure 3 As shown, this embodiment also provides a car seat, including a seat body and a headrest as described in any of the above embodiments. The car seat manufactured using the headrest of this invention can significantly improve driving comfort and also enhance driving safety.

[0050] Specifically, the seat body is provided with a headrest fixing position, and the seat headrest is placed in the headrest fixing position and connected to the seat body.

[0051] Specifically, the connection method between the seat headrest and the seat body can be adhesive bonding or other connection methods. This application does not make specific limitations here, as long as the seat headrest is connected to the seat body.

[0052] Example 1

[0053] A seat headrest includes a pillow body 1 having a memory foam layer and a breathable layer on the surface of the memory foam layer. The pillow body 1 includes a main support area 11 and a secondary support area 12 extending from the main support area 11 to the surrounding area. The main support area is a deformable structure. The main support area 11 protrudes from the surface of the secondary support area 12, and the protrusion height of the main support area 11 from the surface of the secondary support area 12 is 40-50mm.

[0054] The main support area 11 is provided with a head support part 111 and a neck support part 112 extending from the head support part 111 to one end of the pillow body 1. The surface of the head support part 111 is formed with a curved surface that matches the characteristics of the human head, and the surface of the neck support part 112 is formed with a curved surface that matches the characteristics of the human neck. The curvature of the curved surface formed by the head support part 111 along the width direction of the pillow body 1 is greater than the curvature of the curved surface formed by the neck support part 112 along the width direction of the pillow body 1.

[0055] The secondary support area 12 includes a cervical spine support portion 121 formed by inward contraction from one end of the pillow body 1. The cervical spine support portion 121 connects with the transition area 13 to form an inclined surface. Specifically, a first arc-shaped structure 124 and a second arc-shaped structure 125 are respectively provided on the edge of the cervical spine support portion 121 away from the main support area 11. Specifically, the cervical spine support portion 121 is trapezoidal in shape.

[0056] The secondary support area 12 also includes a first shoulder support 122 and a second shoulder support 123. The first shoulder support 122 and the second shoulder support 123 are arranged opposite each other on both sides of the main support area 11. The first shoulder support area forms a sloping transition along the width direction of the pillow, and the second shoulder support 123 also forms a sloping transition along the width direction of the pillow. Specifically, the edge of the first shoulder support 122 away from the cervical spine support 121 has a third arc-shaped structure 126, and the edge of the second shoulder support 123 away from the cervical spine support 121 has a fourth arc-shaped structure 127. The side of the first shoulder support 122 near the cervical spine support 121 connects with the cervical spine support 121 to form an arc, and the side of the second shoulder support 123 near the cervical spine support 121 connects with the cervical spine support 121 to form an arc.
