HEADLINER COMPRESSION STIFFENER

摘要

The present invention provides for a vehicle headliner having localized compressed stiffeners to increase rigidity and decrease brittleness. The headliner compression stiffener adds rigidity to the headliner substrate without adding additional cost or additional weight. At least one compression stiffener is added to a vehicle headliner to an area of the vehicle headliner requiring increased rigidity qualities. The stiffener is an elongated indentation formed by firmly compressing an object into the substrate of a headliner. The substrate of the vehicle headliner includes a first predetermined density in areas where the stiffener is not located. A second density is localized in the headliner substrate in the area directly below the indentation of the stiffener. The predetermined first density is lower in measurement than the second density of the substrate directly below the indentation of the stiffener. By increasing density in the area directly below the stiffener indentations, the headliner as a whole is stronger in areas near the stiffener indentations without increasing weight or substantially increasing cost.
