Composite board structure including corrugated fiberboard and combination surface-covering and electrical-wiring arrangement incorporating the board structure

摘要

A composite board structure including a corrugated fiberboard having a liner having an uncovered outer face formed with at least one length of trough-shaped depression which is adapted to have a wire harness disposed therein. The board structure is useful not only as an interior trim for the roof panel of the body structure of an automotive vehicle but as a mount for the wire harnesses connected to some electrical appliances of the vehicle.
