Lining avoiding vehicle panels buckling due to differential expansion - has compensation slits cut through part of its layers and running across the main direction of any emerging tension in the lining piece.

摘要

An extensive, esp. vehicle interior, lining piece of multi-layer fibrous material, like a roof covering (10) or similar is applied to a mounting, esp a bodywork panel (20). It has at least one tension compensation slit (22) which cuts through only part of the layers (12, 14, 16, 18) and runs across the main line of tension arising in the piece due to differential thermal expansion between piece and panel. Also claimed is a process for lining esp. a bodywork panel with the piece entailing the following steps: (a) punching out a suitable lining section from a multi-layer fibrous web, esp corrugated cardboard, (b) cutting the tension-releasing slits in the section, (c) if needed cutting camber slits in the section, (d) applying adhesive to section, panel or both and, (e) pressing the section to the panel.
