Abstract:
A method for the manufacture of a component assembly comprising a sheet metal part and a functional element attached to it by a riveting process or by a riveting and piercing process or by a press-in process, wherein the sheet metal part is provided with an imprint, is wherein the imprint is produced prior to attachment of the functional element and consists of a sequence of regions which are raised and recessed relative to one another and wherein, during the attachment of the functional element this is pressed against the sheet metal part in such a way that the imprint of the sheet metal part leads to a complementary shaping of the functional element in the region of the functional element which comes into contact with the imprint. A sheet metal part and a functional element are also claimed.
