The overall impression of a vehicle's quality is strongly influenced by its interior. This is why high quality materials, tight manufacturing tolerances and the perfect assembly of interior components are critical. One key aspect is the control panel and dashboard, which can always be seen by the front seat passengers. As well as the visual requirements, functional and security requirements also have to be fulfilled. For this reason, the passenger airbag has a predetermined breaking line which is generated using a laser. This »weak point« ensures the safe opening of the airbag at the predetermined breaking line. Due to the heat input when fixing the airbag in place, or because of the mechanical pressure of the control panel, sink marks may appear, which can be recognized under certain light conditions.An objective visual evaluation of this sink marks is difficult and the grained surface makes tactile measurement impossible. The surfaceCONTROL systems enable fast, objective evaluations to be made of the characteristics of any shape deviations, both on grained and smooth surfaces.
