Abstract
A non-destructive method of measuring tear lines formed in a surface of a resilient automotive trim panel configured for overlaying an inflatable safety device includes the steps of periodically selecting a trim panel for testing from a flow of in-process trim panels, mounting the selected trim panel to a mounting jig configured to support a region of the selected trim panel adjacent a tear line and to temporarily splay said selected trim panel to expose opposed edges forming at least a portion of the tear line, scanning a 3D image of the opposed edges, storing said 3D image as data in an associated processor, and removing the selected trim panel from the mounting jig. The mounting jig includes a base forming upwardly facing longitudinally elongated converging guide surfaces intersecting at a common apex, and a cover member forming downwardly facing longitudinally elongated converging support surfaces intersecting at a common apex.
