[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a structure of an interior cushioning material which is used for an interior of an automobile and has a complex skin shape which improves the appearance and at the same time reduces the impact of a collision with an occupant.

[0002]

[Prior art]

 Conventionally, the interior cushioning material for automobiles, which is used for the interior of automobiles and the like and is intended to improve the appearance and at the same time reduce the impact of impact on occupants, is a mold made of sheet metal or a synthetic resin molded product of a predetermined shape. In general, foamed flexible polyurethane is placed on top of this, and the surface material on which the foamed flexible polyurethane is placed is coated with leather or artificial leather as the skin, and the periphery of the skin is folded, sewn, or bonded. It is a target.

[0003]

[Problems to be solved by the invention]

 However, in the above-mentioned conventional device, a complicated process is required to form protrusions at regular intervals in the manufacturing process, and the process becomes expensive. There is a problem that it is very disadvantageous in an automobile or the like that adopts an interior having a shape.

[0004] In view of the above, the present invention has been made to solve the above-mentioned problems of the prior art, and forms certain protrusions such as bulges, irregularities, and folds of an automobile interior cushioning material which can be obtained at lower cost. It is intended to ensure flexibility in the whole or necessary part of the complex shaped epidermis.

[0005]

[Means for Solving the Problems]

 For this purpose, the present invention provides a car interior cushioning material made of leather or artificial leather, woven cloth, etc., with a protruding portion such as a bulge, unevenness, or folds formed on the skin, and a back surface of the skin. The foamed soft polyurethane is injected from the direction and filled into the protruding portion of the skin, or is formed into a predetermined shape while leaving a void portion in the protruding portion.

[0006]

[Embodiment of the invention]

 In the practice of this invention, pins made of leather or artificial leather, woven fabric, etc. were placed on both ends of a mold having a flexible surface such as silicone rubber at intervals of 20 mm, and holes of 22 mm were made in the skin. At the beginning, by fitting to the pin, it is possible to form a state in which folds are formed on the skin at regular intervals. At the same time, the skin is pulled in a direction parallel to the "folds" formed on the skin, and the tension of the formwork is pulled. It is also possible to form pins at 200 mm intervals on the formwork in the direction while providing fitting holes at 197 mm intervals in the above-mentioned pulling direction of the skin to make it easier to form "folds" on the skin. A thermal adhesive resin film layer or a flexible foamed resin sheet layer is placed on the entire surface of the skin or on the back surface of the necessary portion, and then foamed soft polyurethane is injected from the back surface direction of the skin and the foaming pressure is applied to the above-mentioned skin. Filled by filling into the minute protrusions and forming into a predetermined shape, the foamed soft polyurethane penetrates into the leather, artificial leather, woven fabric, etc., which becomes the skin, and the thermal adhesive resin placed on the back of this skin It will be blocked by the film layer or the soft foamed resin sheet layer. Therefore, foamed flexible polyurethane foams reliably without penetrating into the skin, and forms leather, artificial leather, woven fabric, etc., which is the skin that forms protrusions such as bulges, irregularities, and folds, into its complex shape. While it can be accurately formed into a predetermined shape in combination, the softness of the material can be reliably ensured without hardening the leather or artificial leather, woven cloth, or the like that becomes the skin. Therefore, in addition to the improvement of the appearance required as a cushioning material for automobile interiors, the relaxation of the impact force due to the flexibility of the skin is not impaired.

[0007] Further, when a void is left without filling the entirety of the protruding portion of the skin with the foamed flexible polyurethane, a cured portion due to the foamed flexible polyurethane does not occur on the surface of the protruding portion. The entire surface does not need to be adhered to the back surface of artificial leather, woven fabric or the like.
