  • Patent number: 10752183
    Abstract: A laminated composite interior part includes a first member made of synthetic resin and having a mating surface; and a second member made of elastically deformable synthetic resin and having a plate portion substantially parallel to the mating surface. The plate portion has integrally-formed and interspersed protrusions protruding toward the mating surface. The second member is placed on the first member with distal end portions of the protrusions being in contact with the mating surface. Cushioning properties are provided by elastic deformation of the protrusions, caused as the protrusions' distal end portions are relatively pressed against the mating surface. Flexural rigidity of each of the protrusions against a compressive load is anisotropic about its axis, so that the protrusion is flexurally deformed in one direction about its axis with the distal end portion thereof sliding on the mating surface. Surface roughness of the mating surface is less than 0.20.

  • Publication number: 20200047488
    Abstract: A protective sheet is to be laid on an endless belt sheet and covers a surface of the endless belt sheet to protect the surface. When the protective sheet is laid on the endless belt sheet, the bending stiffness of the protective sheet is lower in the circumferential direction of the endless belt sheet than in the width direction that is orthogonal relative to the circumferential direction. Thus, the risk of being bent and damaged of the endless belt sheet is minimized and the cumbersomeness of the operation of replacing the endless belt sheet is remarkably reduced by using such a protective sheet.
