  • Patent number: 12571416
    Abstract: A riveted joint in which a rivet foot of a rivet element is driven into a component with a setting force, in particular by spreading the rivet foot. The rivet foot has a reduced cross-section in the still undeformed state and has an expanded cross-section in the driven-in state. The rivet foot is designed as a bistable spring portion that has two equilibrium states, namely the undeformed cross-section-reduced state and an expanded spread state. As a result of the setting force being applied, the rivet element changes from the undeformed state to the spread state, in which the rivet foot is spread with an expanded cross-section in the component, in particular without the build-up of a springback force that biases the rivet element towards the undeformed state.
