First Claim
Patent Images
1. A method for measuring gaps and hollow spaces in motor vehicle body construction, the method which comprises:
- introducing a filler element into one of a gap and a hollow space in a motor vehicle body, the one of the gap and the hollow space having a given dimension, the filler element being an element selected from the group consisting of a compressible sealing strip, an elastomeric filler element, a plastomeric filler element, an expansion element, and a dimensionally unstable body;
providing a probe of an ultrasonic testing unit such that the filler element encloses the probe; and
measuring the given dimension of the one of the gap and the hollow space by using the ultrasonic testing unit.
