Functional component, component assembly comprising a functional component, and method for securing a functional component to a holding component

A composite component having

• at least one functional component for a motor vehicle, and
• having a holding component,
• wherein the functional component is secured to the holding component by pressing a connecting element of the functional component into a depression provided in the holding component,
• wherein the connecting element protrudes from a base body of the functional component in a press-in direction in a non-deformed state and is designed to be converted into a deformed state by applying a force acting in the press-in direction to the base body, in which the connecting element is widened in a free end area and the free end area of the connecting element penetrates a wall of the holding component delimiting the depression of the holding component in the circumferential direction,
• wherein the base body of the functional component includes a contact surface extending around the connecting element which, in a coupled state of the functional component, in which the functional component is secured to the holding component by pressing the connecting element into the depression, abuts a support surface of the holding component,
• wherein a functional module of the functional component is provided by a partial area of the base body facing away from the contact surface;
• wherein the functional module, designed in particular to secure a further component to the functional component, is designed to produce a welded connection of the functional component to a further component and comprises a pin-shaped extension which is aligned with the connecting element, wherein the contact surface is formed on a side of a collar-like web of the functional component facing away from the pin-shaped extension and extending around the pin-shaped extension;
• and
• wherein the at least one depression has the shape of a truncated cone that widens counter to the press-in direction.
