Abstract
Presented are devices for measuring dimensions of tear seams, methods for making/using such devices, and handheld clamp calipers for gauging material thicknesses of tear seams in passenger airbag breakaway panels. A handheld or automated measurement tool for determining seam dimensions includes first and second jaws operatively attached to a calibrated scale. The calibrated scale displays a measurement value fora dimension of a seam. The first jaw includes a first jaw tip projecting from a first jaw mandible. The second jaw includes a second jaw tip projecting from a second jaw mandible, which is movably attached with the first jaw mandible. Each of the jaw tips contacts a respective surface of the seam. An interior edge of the second jaw tip is disposed at an oblique angle of less than 90 degrees from an interior edge of the second jaw mandible.
