Molded laying interior material for vehicle
The present invention discloses a molded laying interior material for a vehicle includes a decorative layer that faces a vehicle compartment and a buffer material layer that faces a vehicle body panel. The decorative layer has a first concavo-convex shape formed by press molding on a side of the vehicle compartment. The buffer material layer has a second concavo-convex shape formed by press molding a buffer material on a side of the vehicle body panel. The buffer material has a fiber structure in which fibers are oriented in a thickness direction in the fiber structure The decorative layer and the buffer material layer are at least laminated and integrated.
1. A molded laying interior material for a vehicle, comprising:
a decorative layer that faces a vehicle compartment; and
a buffer material layer that faces a vehicle body panel;
the decorative layer has a first concavo-convex shape formed by press molding on a side of the vehicle compartment;
the buffer material layer has a second concavo-convex shape formed by press molding a buffer material on a side of the vehicle body panel;
the buffer material has a wavelike shape in which a web is repeatedly folded back in a thickness direction in the wavelike shape such that pleats are formed;
the decorative layer and the buffer material layer are at least laminated and integrated;
the second concavo-convex shape of the buffer material layer includes a first cross-sectional shape along a lamination direction of the pleats and a second cross-sectional shape along a width direction of the buffer material; and
a height from a lowest part to a highest part in the first cross-sectional shape along the lamination direction of the pleats is larger than a height from a lowest part to a highest part in the second cross-sectional shape along the width direction of the buffer material when the decorative layer is disposed on a bottom of the vehicle compartment.
