Abstract

A locking mechanism (1), in a motor vehicle, includes two elements (2, 4) that abut one another along a contact region (10). At least one element (2, 4) has a coating (9) at least in the contact region. The coating alters under stress during an accident, such that the contact region (10) between the two elements becomes larger and/or a coefficient of friction between the two elements increases.
