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.

Claims

1. A laminated composite interior part, comprising:

a first member made of a synthetic resin and having a mating surface; and

a second member which is made of an elastically deformable synthetic resin, and which has a plate portion substantially parallel to the mating surface, the plate portion being provided with multiple protrusions which are formed integrally with the plate portion to be interspersed on the plate portion, and which protrude toward the mating surface such that the plate portion and the mating surface cooperate to define a space between the plate portion and the mating surface, and the second member being placed on the first member with distal end portions of the protrusions being in contact with the mating surface,

the laminated composite interior part having cushioning properties provided by elastic deformation of the protrusions, which is to be caused as the distal end portions of the protrusions are relatively pressed against the mating surface,

flexural rigidity of each of the protrusions against a compressive load being 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, and

surface roughness of the mating surface being less than 0.20.

2. The laminated composite interior part according to claim 1, wherein

the protrusion has an asymmetrical longitudinal section, and the protrusion is flexurally deformed while sliding in the one direction determined according to the asymmetrical shape when the distal end portion thereof is pressed against the mating surface.

3. The laminated composite interior part according to claim 1, wherein

the protrusion has its centerline tilted with respect to a direction normal to the plate portion located at a base end portion of the protrusion, and the protrusion is flexurally deformed while sliding to a side to which the centerline is tilted.
