Claims
- 1. A method for mounting a protecting material comprising:mounting a material for protection by an adhesive sheet to a required portion, said material for protection comprising a rigid polyurethane foam having a compression stress of at least 3 kg/cm2, said material for protection having a shape of a board, concavities arranged on at least one surface thereof, and walls for dividing the concavities so that when a predetermined shock corresponding to the compression stress of at least 3 kg/cm2 is applied to the material for protection, at least one of the walls is crushed and destroyed, and enters at least one of the concavities adjacent thereto to thereby absorb the shock, wherein the adhesive sheet comprises a base foam material and an adhesive layer formed thereon.
- 2. The method for mounting a protecting material according to claim 1, wherein a density of the foam material is 0.005 to 0.5 g/cm3, and a thickness of the base foam material is 0.5 to 5 mm.
- 3. The method for mounting a protecting material according to claim 1, wherein the protecting material is for protecting a head of a passenger including a driver.
- 4. The method for mounting a protecting material according to claim 1, wherein the foam material is a soft polyurethane foam, a polyolefin resin foam, or a foam rubber.
- 5. The method for mounting a protecting material according to claim 1, wherein said adhesive layer is formed of an acrylic adhesive material or a rubber adhesive material.
- 6. The method for mounting a protecting material according to claim 1, wherein a density of the foam material is 0.005 to 0.2 g/cm3.
- 7. The method for mounting a protecting material according to claim 1, wherein a thickness of the adhesive layer is 0.01 to 1 mm.
