Description

[Detailed description of the invention] (Industrial application field) This invention relates to a skin assembly structure for bucket-type seats. Specifically, it is a skin assembly suitable for bucket-type seats for vehicles that has good retention of occupants. It is related to the structure of

(Prior Art) Conventionally, a seat for an automobile driver's seat or the like is formed by attaching a skin assembly to the support surface of a cushioning holder of a seat bag designed to have a predetermined bucket concave shape. This skin assembly is made by suitably joining pre-cut skin and core polymer layers to follow the shape of the support surface of the cushioning holder of the seat bag.
And seats such as those for the driver's seat in recent cars,
Ride comfort and sports performance are required more than ever before, and cars are becoming more strongly structured with a bucket concave shape.

(Problem to be solved by the invention) However, the seat back, which has a strong structure with a bucket concave shape, has a large internal retraction of the supporting surface due to the load applied during use, and when it returns to the load-free state, the outer skin surface wrinkles. However, there was a problem in that the appearance was unsightly.

In addition, conventional skin assemblies polymerize a core layer with cushioning properties under the skin to ensure the resilience of the skin surface in a load-free state, but the skin surface of seat bags still has the problem of wrinkles. Ta.

Therefore, this invention was an attempt to solve the above-mentioned conventional problems, and it is of course comfortable to sit on, has a soft skin surface, and has a seat back or seat shoe that is comfortable to sit on after a load is applied. To provide an epidermal assembly structure capable of preventing the occurrence of wrinkles on the epidermal surface of hair.

(Means for Solving the Problems) In order to solve the above problems, the means of this invention is to provide a seat cushion or a seat bag that is attached to a support surface in the shape of a bucket recess in a cushioning holder of a seat cushion or a seat bag, and that is A skin assembly consisting of a polymerized layer of a layer and a backing fabric, in which the polymerized layer is cut and bonded along the supporting surface, and is drawn into the interior at least during use to form a deep recess. The skin assembly structure has a nape-like sheet having resilience arranged in the core layer of the skin assembly part corresponding to the holder part.

(Function) The skin assembly is applied to a seat cushion or a seat bag to form a predetermined bucket-shaped seat. The assembly portion in which the core layer is arranged has resilience. The epidermal assembly site where the core layer of the nape-like sheet is located has strong restorability due to the strong repulsive force of the nape.

(Example) Next, an example of the present invention will be described based on the drawings.

FIG. 1 shows a seat bag 1 to be made into a bucket-type seat, and a skin assembly 4 formed by bonding a polymer layer 8 to a concave support surface 3 of a cushioning holder 2 designed in a bucket-concave shape is provided as appropriate. It is coated with.

The holding body 2 has an elastic member such as a metal spring body and a metal plate arranged on a hard frame body such as a metal frame,
The support surface 3 side is a structure formed into a curved surface that is deeply recessed inwardly (not shown), with padding materials etc. attached at appropriate locations as necessary.

When the holder 2 is attached to a vehicle and a load is applied to the support surface 3, it becomes a deep concave surface inward, and when the load is released, it returns to its original state, but the part where the support surface 3 is particularly deeply retracted. is difficult to restore, and even if the surface 5 of the skin assembly 4 that covers this area is returned to its original state without a load, wrinkles will occur on the surface 5 of the skin. Note that the wrinkled portion is located on the holder 2.
Although it differs depending on the shape of the bucket recess on the support surface 3,
In the case of the holder 2 of this example, as shown in FIG.
The horizontal belt portion B on the upper side of the support surface 3 is the wrinkle-generating portion.

The skin assembly 4 is mainly composed of a skin 5, a core layer 6 of a raised sheet having resilience, and a polymer layer 8 of a backing fabric 7, and is cut into a predetermined size along the curved surface of the support surface 3. are joined by sewing or welding to form a predetermined size that covers the support surface 3 of the holder 2, or the support surface 3 and its periphery. 9 indicates a sewn portion.

The skin 5 is made of woven cloth such as fabric, synthetic resin sheet, leather, or the like. The core layer 6 of the nap-like sheet is made of a carpet fabric made of a material in which the naps of a certain length are arranged in a dense manner, the naps have a strong repulsive force, and the bristles have a strong restoring force after being pressed. The back base fabric 7 is made of a thick layer of nonwoven fabric or felt fabric. Further, in the skin assembly 4 of this example, a portion covering the support surface 3 is made of a polymer layer 8, and a peripheral portion is formed of a bonding skin 10.

Thus, the skin assembly 4 is attached to the support surface 3 of the holder 2 with the skin 5 facing outward, forming the seat bag 1 of this example. The seat bag 1 is used by being attached to the driver's seat of an automobile together with a separately prepared seat cushion (not shown).

Since the entire support surface of the seat back 1 of this example is covered with the skin 5 made by polymerizing the core layer 6 of the nap-like sheet, it can sufficiently follow the shape change of the holder 2 when the car is running. , and the restorability of the five surfaces of the skin in the unloaded state after loading is sufficient, and no wrinkles occur in any part.

The embodiment described above includes the entire surface of the support surface 3 of the holder 2, the outer skin 5, the core layer 6 of the raised sheet, and the back base fabric 7.
The skin assembly 4 is made of a polymerized layer 8 of
As shown in the skin assembly 14 shown in FIG. 5, a polymer layer 18 consisting of the skin 5, a cushioning core layer 16 such as polyurethane, and the back fabric 7 is divided along the curved shape of the support surface 3. The outer skin 5 and the core layer 6 of a nap-like sheet having resilience are attached to the back base fabric only in the part that is bonded and becomes the wrinkle-generating part of the support surface 3 of the holder 2, for example, corresponding to the belt part B. A structure in which a polymer layer 8 with 7 is arranged and bonded may be used.

Furthermore, although the above-mentioned embodiments have been described in terms of preventing wrinkles from forming on the skin of a seat bag, prevention of wrinkles from forming on the skin of a seat cushion can also be carried out in the same manner as in the above-mentioned embodiments.

(Effects of the invention) According to the invention, since the skin assembly can be applied along the shape of the holder support surface of the seat cushion or seat bag, a good bucket-shaped seat can be obtained.

The skin assembly in the present invention has a structure consisting of a polymer layer of the skin, a core layer of a nap-like sheet, and a backing fabric, or a polymeric layer of the skin, a core layer with normal cushioning properties, and a backing fabric, and can prevent wrinkles. By placing and bonding a polymer layer of the epidermis, the core layer of the napped sheet, and the back base fabric in the generated area,
It is possible to prevent wrinkles from occurring on the surface of a bucket-shaped seat bag or seat cushion.

The skin assembly in the present invention is composed of a polymer layer of the skin, a core layer, and a backing fabric, and has good restorability in a load-free state. The outer skin part corresponding to the holder part that is drawn into the interior and becomes a deep recess when the sheet is used is coated with a core layer of a raised sheet that has resilience to the outer skin, and a polymeric layer of backing fabric. Because they are arranged and bonded together, the polymer layer on which the core layer of the napped sheet is arranged has strong shape recovery properties in the unloaded state after being loaded with a load, and can be made to have a good appearance without wrinkles. Further, since the polymer layer portion in which the core layer of the napped sheet is disposed has elasticity, the touch feeling of the surface of the portion is soft. Therefore, the riding comfort of the bucket seat using the skin assembly of the present invention is good.
