Abstract

PURPOSE:To simply provide liner part with good efficiency to a helmet by a method in which the liner part is molded integrally of a cloth, etc., and a buffer material so as to provide it with a shape keepability. CONSTITUTION:A raw material 1 formed by bonding a cloth 3 having good touch feeling to polyurethane foam 2 is molded by heat press with a bowl-shaped mold. A shallow, long, and round recession 5 is provided on the bottom of a buttom force 4, and a recession 7 of the same shape is also provided for a top force 6. The raw material 1 in the recessions 5 and 7 remains unmolded by heat press to leave the thickness of the polyurethane foam intact. The bowl-shaped portion formed by heat press is cut off from the raw material 1 and inversed to obtain liner part 9 to be bonded to the inner surface of a helmet. The liner part 9 is bonded to the inner surface of the helmet with the helmet. The bonding of the liner part to the helmet can thus be simply performed with good efficiency without needs to fix a buffer material additionally.

Description

【発明の詳細な説明】 本発明は、主として単車用のヘルメットの内装方法に関
するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention mainly relates to a method for interior fitting a motorcycle helmet.

単車用のヘルメットの内側には、装飾用の布地等を貼着

める。Decorative fabric, etc. is pasted on the inside of a motorcycle helmet, and cushioning material is fixed to protect the head, but the cushioning material must be molded and fixed separately from the fabric, etc. Moreover, since the fabric does not have shape retention properties, it is very difficult to handle, and the work of applying it is extremely difficult.

である。Therefore, the present invention makes it possible to easily and efficiently carry out interior work using inner lining materials by integrally molding fabric and cushioning materials and giving them shape retention properties.
The purpose of this invention is to provide a method for interior fitting a helmet.

接着する。The present invention creates an inner lining material with a cushioning material integrally molded by heat-pressing a raw material made of polyurethane foam and fabric bonded into a bowl shape, leaving the top abutment part round, and this is used as an inner lining material for the inside of the cap body. This is a method for interior fitting a helmet, which is characterized in that the interior of the helmet is pasted on the interior of the helmet. That is, in FIG. 1, 1 is a raw material, which is made of a polyurethane foam 2 with a thickness of about 15 mm and a cloth 3 with a good feel bonded to it. This raw material 1 is heat pressed using a bowl-shaped (slightly oval) mold (Fig. 2).A shallow, oval depression 5 is provided at the bottom of the female mold 4, and a male mold A similar depression 7 is also provided in the direction of 6. By doing so, the original thickness of the polyurethane foam will remain in the raw material 1 at the depression 5.7 without being heat pressed.
. Next, the heat-pressed bowl-shaped portion is cut out from the raw material 1 and turned over to complete the inner patch material 9 (FIG. 3). This inner patch material 9 is adhered to the inside of the cap body with an adhesive.

効率良く行うことができる効果がある。The present invention is as described above, and since the i-hit can be integrally molded by heat-pressing the polyurethane foam to which the fabric is bonded, it is possible to eliminate the trouble of separately molding and fixing the cushioning material, and also to attach the fabric to the fabric. Since shape retention properties can be imparted, the work of attaching the inner patch material to the cap body can be carried out extremely easily and efficiently.
