Description

Technical Field

[0001] This utility model relates to the field of automotive seat technology, and in particular to a backrest mounting structure for automotive seats and an automotive seat. Background Technology

[0002] Installing a plastic back panel on the back of a car seat not only serves a decorative purpose but also enhances its support. Since the back panel is stronger than foam, a small table or hanging items can be placed on it.

[0003] In existing car seats with backrests, some methods involve adding protrusions to the foam component during backrest assembly. When the backrest is fitted onto the seat cover, these protrusions are compressed, and the interference fit of the foam eliminates the gap between the backrest and the cover. However, this method is susceptible to the size of the cover panels and the hardness of the foam, resulting in poor aesthetic consistency between the two. Furthermore, the added protrusions cause the edges of the foam to protrude significantly above the backrest, creating an uneven appearance that fails to meet the high requirements of OEMs. Another method involves adding a support structure inside the foam component to eliminate the gap. However, this approach is not only complex in design but also costly. Utility Model Content

[0004] In view of the above-mentioned shortcomings of the existing technology, the technical problem to be solved by this utility model is to propose a back panel mounting structure for car seats and a car seat that provides a tighter fit between the cover and the back panel, reduces the risk of gaps, and is simple in structure, easy to install, and low in cost.

[0005] The technical solution adopted by this utility model to solve its technical problem is to propose a back panel mounting structure for automobile seats, comprising:

[0006] The backrest body includes a foam component, and the back side of the foam component has a rearward opening.

[0007] A cover is provided to cover the outer surface of the foam, and the inner surface of the cover is provided with a support strip connected to the cover. The support strip is provided along the edge of the opening and abuts against the edge of the opening.

[0008] A back panel is provided over the opening and is positioned on the faceplate;

[0009] The support strip supports the faceplate covering it, and the portion of the faceplate supported by the support strip is at least partially in contact with the backplate.

[0010] Furthermore, the support strip is sewn onto the inner surface of the face mask by stitching.

[0011] Furthermore, the support strip has an inner surface and an outer surface that are arranged opposite to each other, and the inner surface is in contact with the foaming component, while the outer surface is in contact with the inner surface of the faceplate.

[0012] Furthermore, the support strip has a hook along its length, the hook abuts against the foam and generates a rebound force, the rebound force causing the cover covering the support strip to abut against the back plate.

[0013] Furthermore, the side of the support strip along its length and opposite to the hook is sewn onto the inner surface of the face mask by stitching.

[0014] Furthermore, the support strip is made of plastic, and the cover is wrapped around the foam, so that the support strip undergoes elastic deformation after it abuts against the foam.

[0015] Furthermore, the wall thickness of the support strip is less than or equal to 1.5 mm.

[0016] Furthermore, the opening is configured as a polygon, and the supporting strip is arranged on one or more edges of the opening.

[0017] Furthermore, the length of the support strip is less than the length of its corresponding edge.

[0018] This utility model also proposes a car seat, wherein the car seat is equipped with the aforementioned back panel mounting structure.

[0019] Compared with the prior art, the present invention has at least the following beneficial effects:

[0020] In this invention, a support strip is provided on the inner surface of the cover and connected thereto. When the cover is wrapped around the foam, the support strip will support the cover covering it, so that the cover at this position can keep tightly fitted to the back panel, reducing the risk of gaps, improving the matching degree between the cover and the back panel, and having a greater tolerance for changes in the softness and hardness of the foam and the size of the cover pieces. It also reduces the dependence on the assembly protrusions on the foam and makes the matching surface between the cover and the back panel smoother.

[0021] In this invention, the support strip is sewn onto the inner surface of the face mask, which is simple to sew and has a simple structure, is easy to install, and has low cost.

[0022] In this invention, a hook is formed along the length of the support strip. The hook abuts against the foaming part, and the resulting rebound force causes the cover covering the support strip to come into contact with the back plate, making the cover and the back plate fit together tightly and improving their matching effect.

[0040] like Figures 1-4 As shown, the backrest mounting structure for a car seat in this embodiment mainly includes: a backrest body 1, a cover 2, a support strip 3, and a back panel 4. The backrest body 1 includes a foam component 10 and a frame. The foam component 10 is mounted on the frame, and its back side has a rearward-opening opening 100 for mounting the back panel 4. The cover 2 covers the outer surface of the foam component 10, and its inner surface has a support strip 3 connected to it. The support strip 3 is positioned along the edge of the opening 100 and rests against it. The back panel 4 covers the opening 100 and is located on the cover 2. The back panel 4 is made of plastic, which enhances the aesthetics of the car seat and allows for the integration of small tables or hooks. The plastic back panel 4 has higher strength than the foam component 10, which, as a comfort component, has relatively lower strength. In actual use, the support strip 3 supports the cover 2, and the part of the cover 2 supported by the support strip 3 is at least partially in contact with the back plate 4. The support strip 3 supports the cover 2 near the edge of the opening 100, ensuring that the cover 2 and the back plate 4 fit more tightly at the edge of the opening 100, reducing the risk of gaps between the back plate 4 and the cover 2.

[0041] In this embodiment, a support strip 3 is provided on the inner surface of the cover 2 and connected thereto. When the cover 2 covers the foam 10, the support strip 3 supports the cover 2 covering it, so that the cover 2 at this position can keep tightly fitted to the back plate 4, reducing the risk of gaps, and the cover 2 and back plate 4 have a better matching degree. Moreover, it has a greater tolerance to the changes in the softness and hardness of the foam 10 and the size of the cover 2 pieces. It also reduces the dependence on the assembly protrusions on the foam 10, and the structure of the foam 10 can be designed to be simpler, without the need to design numerous assembly protrusions. Furthermore, the matching surface between the cover 2 and the back plate 4 is smoother, ensuring better consistency in appearance.

[0042] like Figures 3-6 As shown, in this embodiment, the support strip 3 is sewn to the inner surface of the face cover 2 by the stitch 5. Compared with other connection methods, sewing the support strip 3 to the face cover 2 by the stitch 5 is both convenient and secure.

[0043] It should be explained that the support strip 3 is made of plastic and is a thin-walled component. Therefore, a sewing needle can directly pierce the support strip 3 and sew it to the inner surface of the cover 2 through the thread 5. The wall thickness of the support strip 3 is less than or equal to 1.5 mm, which facilitates sewing and connection while ensuring that the support strip 3 can undergo elastic deformation to provide sufficient support to hold the cover 2 up.

[0044] The support strip 3 has a hook 33 along its length, and the hook 33 is integrally formed on the support strip 3. The hook 33 abuts against the foam 10 and generates a rebound force. This rebound force lifts the cover 2 covering the support strip 3 towards the back plate 4, so that the cover 2 at this position is in close contact with the back plate 4. The side of the support strip 3 along its length opposite to the hook 33 is sewn to the inner surface of the cover 2 by stitch 5, ensuring a firm connection between the support strip 3 and the cover 2. In actual use, one side of the support strip 3 is firmly connected to the cover 2, while the other side provides a rebound force, ensuring a tight fit between the cover 2 and the back plate 4. The support strip 3 in this embodiment can be manufactured by extrusion molding, which is convenient.

[0045] The support strip 3 has an inner surface 31 and an outer surface 32 that are arranged opposite to each other. The inner surface 31 of the support strip 3 is adapted to the edge of the opening 100 on the foam 10 at its corresponding installation position. The outer surface 32 of the support strip 3 is adapted to the corresponding edge on the back plate 4. The inner surface 31 of the support strip 3 is in contact with the foam 10, and the outer surface 32 of the support strip 3 is in contact with the inner surface of the cover 2.

[0046] In this embodiment, the support strip 3 is made of plastic. The cover 2 covers the foam 10. After the support strip 3 abuts against the foam 10, the support strip 3 undergoes elastic deformation. The force generated by the elastic deformation of the support strip 3 acts on the cover 2, so that the cover 2 can fit tightly against the back plate 4.

[0047] In practical use, the support strip 3 of this embodiment is sewn onto the inner surface of the cover 2. The sewing is simple. Compared with the complex support structure designed in existing car seats to support the cover 2 and ensure the fit between the cover 2 and the back panel 4, the support strip 3 of this embodiment has a simple overall structure, is easy to install, and is low in cost. A hook 33 is formed along the length of the support strip 3. The hook 33 abuts against the foam 10. The rebound force generated by the support strip 3 makes the cover 2 and the back panel 4 covering the support strip 3 fit tightly against each other, resulting in a better matching effect between the cover 2 and the back panel 4.

[0048] like Figure 3 As shown, the opening 100 in this embodiment is a polygon. The figure illustrates that the opening 100 in this embodiment is roughly rectangular, i.e., quadrilateral, but it is not limited to this shape. It can also be designed as a corresponding polygonal structure according to the user's actual needs. Supporting strips 3 are arranged on one or more edges of the opening 100. The supporting strips 3 support the corresponding edges of the opening 100, ensuring that after the supporting strips 3 support the faceplate 2 at the edge of the opening 100, it fits tightly against the back plate 4.

[0049] It needs to be explained that since the backrest body 1 itself has a frame with sufficient support strength and many supporting wires, the upper edge of the opening 100 is close to the wires on the frame and has sufficient strength to support the cover 2. Therefore, it is unnecessary to arrange the support strip 3 of this embodiment at the upper edge of the opening 100. As for the side edge of the opening 100, its length is relatively long and the distance from the supporting wires is relatively far. Its support strength depends on the softness and hardness of the foam 10. Therefore, configuring the support strip 3 of this embodiment can effectively improve the support effect on the cover 2 at this point, thereby ensuring that the cover 2 fits tightly with the back panel 4, and is less affected by the softness and hardness of the foam 10.

[0050] In this embodiment, the length of the support strip 3 is less than the length of the edge of the corresponding opening 100, so it is not necessary to arrange the support strip 3 along the entire edge of the opening 100. Where it is necessary to strengthen the support, the support strip 3 of this embodiment can be set. Of course, multiple support strips 3 can also be set on the edge of the same opening 100. The multiple support strips 3 can be arranged at intervals, and the arrangement of the support strips 3 has a high degree of freedom.

[0051] When the back panel 4 mounting structure of this embodiment is applied to a car seat, the car seat is equipped with the back panel 4 mounting structure of this embodiment.

[0052] The mounting structure for the back panel 4 of a car seat in this solution includes: a backrest body 1, comprising a foam component 10, the back side of which has a rearwardly opening 100; a cover 2, covering the outer surface of the foam component 10, and the inner surface of the cover 2 having a support strip 3 connected to the cover 2, the support strip 3 being arranged along the edge of the opening 100 and abutting against the edge of the opening 100; and a back panel 4, covering the opening 100 and positioned on the cover 2; the support strip 3 supporting the cover 2, and at least partially abutting the back panel 4 at the position supported by the support strip 3 on the cover 2. This design offers at least the following advantages: a tighter fit between the cover 2 and the back panel 4, reducing the risk of gaps; and a simple overall structure, convenient installation, and low cost.
