Claim 0:
1. A method for joining a first component formed of a thermoplastic material having formed integral therewith a rivet formed of the thermoplastic material with a second component having a rivet hole, wherein the rivet hole forms a rivet hole inlet in a first surface of the second component and a rivet hole outlet in a second surface of the second component, and wherein the second component forms in the second surface a structured rivet head accommodating portion having an inlet and an outlet and being disposed in a region of the rivet hole outlet, wherein at least one of: the structured rivet head accommodating portion and at least the second surface is metal-coated so that a substance-to-substance connection between the first component and the second component is not obtainable, the method comprising:
inserting a free end of the rivet via the rivet hole inlet into the rivet hole until a unilaterally abutting, inserted position of the rivet reaching through the rivet hole is reached; and
heat staking the free end of the rivet in the inserted position while forming a rivet head, so that the rivet head is at least partially accommodated in the structured rivet head accommodating portion, in order to fix the second component to the first component;
wherein the structured rivet head accommodating portion forms a molding tool during heat staking, so that a heat-staked rivet head is positively accommodated in the structured rivet head accommodating portion;
wherein the rivet has a base portion tapering conically in a direction of its free end; and
wherein the structured rivet head accommodating portion is formed so as to be conically tapering in the direction of the rivet hole inlet so that the structured rivet head accommodating portion inlet is narrower than the rivet head accommodating portion outlet.
