この発明は、車両用ヘッドレストおよびその製造方法に
関し、特にはファブリフク（織布）表皮を被着するヘッ
ドレスト発泡体およびその製造方法に関する。DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a headrest for a vehicle and a method for manufacturing the same, and more particularly to a headrest foam covered with a fabric skin and a method for manufacturing the same.

頭部が接触することから感触の良さが求められている。In recent years, most vehicles are equipped with headrests above the seats of automobiles to ensure the safety of passengers and the like. However, this headrest is not only a safety component, but also a component that greatly affects the comfort of the vehicle, and is particularly required to have a good feel since the heads of the occupants come into contact with the headrest.
そこで、近年ヘッドレストは軟質プラスチック発泡体か

かくされる傾向にある。On the other hand, the plastic foam for headrests to which this fabritta skin is attached is produced by inserting a metal or plastic insert into a split mold having a desired mold cavity, and then using a mounting stay set upright on the insert. The insert is held suspended approximately in the center of the cavity, and a liquid foaming material such as a soft polyurethane foam is injected into the remaining cavity and foamed to encapsulate the insert and mold it into a predetermined shape. Moreover, as mentioned above, there has been a trend in recent years for foams to become softer and softer in order to improve their feel.

いう問題点を惹起しやすい。(Problem to be Solved by the Invention) However, when the plastic foam inside the skin becomes soft, the outer shape of the plastic foam, especially the head holder, is designed so that it bulges out on both sides of the surface when the skin is attached. The side parts that have been bent tend to deform toward the center as the epidermis adheres,
Furthermore, the ridgeline shape that defines the outer shape of the headrest tends to collapse, making it difficult to obtain a predetermined headrest shape. On the other hand, if the plastic foam is soft, it feels good when touched lightly, but when the head presses strongly against the headrest, the inner insert bottoms out, which tends to cause problems such as poor cushioning properties.

る。(Function) In the headrest foam of the first invention, since a highly elastic foam sheet is integrally covered and pasted from the rear surface to both side surfaces, the outer right side and outer periphery of the foam sheet form the back shape of the headrest foam and the main ridgeline. is clearly created. In addition, since both ends of the buffer body built into the front of the insert are arranged so as to cross the inner surface of both sides of the foam sheet, both sides of the foam will collapse toward the center when the fabritta skin, etc. is applied. This makes it possible to obtain a headrest having a predetermined outer shape. Furthermore, the cushioning body relieves the pressing force from the front, and even when the cushioning body deforms, the highly elastic foam sheets on both ends and both sides connected by the foam act to suppress the deformation of the cushioning body. Therefore, the impact mitigation of the shock absorber becomes more effective.

In other words, when a foam sheet is attached from the rear surface of the headrest to the corresponding portions of both sides, a cushioning material is inserted between the two sides, so that the foam sheet is held in a predetermined position and in close contact with the cavity surface. Therefore, even when the liquid foaming raw material is foamed, foam molding can be performed without the foam sheet falling into the cavity and without causing positional displacement. In addition, by attaching the buffer to the front surface of the insert in advance and inserting the buffer together with the insert device, the buffer can be inserted between the inner surfaces of both sides of the foam sheet while always positioning the buffer in a predetermined space within the cavity. This makes it possible to wipe the foam headrest, and it also makes it possible to incorporate a shock absorber at a predetermined position within the headrest foam.

系発泡シート等が好適である。The headrest foam 40 consists of a cushion body 10 having a desired columnar three-dimensional shape and a reinforcing insert 20 encapsulated therein. The cushion body 10 is mainly composed of a soft polyurethane foam, and inside the cushion body 10, in particular, in the front surface of the reinforcing insert 20, there is a sheet-shaped or block-shaped cushion body 11 having a predetermined thickness, which is approximately the front surface of the headrest. It is built in so that it extends parallel to both sides. It is preferable that this buffer 11 is adhered to the front surface of the insert so that the stress or deformation applied to the buffer 11 is supported by the insert. This buffer 11 acts as a secondary shock absorbing buffer when the impact pressure applied to the front surface of the headrest cannot be absorbed and alleviated by the soft polyurethane foam layer on the surface layer. It is made of plastic foam, which is more elastic than polyurethane foam. Preferred foams include closed cell polyolefin foams and rubber foams. Note that instead of these, a polyurethane foam having a higher density than the soft polyurethane foam of the surface layer, in other words, a polyurethane foam having a lower expansion ratio, may be used as the buffer. On the other hand, a plastic foam sheet 12 having the same high elasticity as the cushioning body 11 is integrally covered and pasted on the rear surface and the outer surface of both sides of the cushion body 10, approximately at the ridge line R with the front surface. The ends of the built-in buffer body 11 are abutted within the I3 portions on both sides. Note that the contact between the foam sheet 12 and the ends of the cushioning body 11 is made by bending both ends of the cushioning body 11 in the same direction as shown in the figure, so that they are in surface contact with each other, and the cushioning body 11 between both sides R13 of the foam sheet is inserted. It is preferable to have them touch each other like a board. In addition, when abutting the two, it is preferable to fix the two using adhesive means such as double-sided adhesive tape. As the foamed sheet 12, a highly elastic polyolefin foamed sheet having the same closed cell structure as described above is suitable.

A headrest foam 40 having seams 2 integrally coated and adhered to its outer surface is obtained. Therefore, by using the liquid foaming raw material to be injected as a material that has a hardness lower than that of the foam sheet 12 and the cushioning body 11 when it becomes a foam, in other words, a soft foam, the rear surface is moderately hard and the front surface has cushioning properties. This makes it possible to provide a headrest foam with different hardness.
