Abstract

In order to provide a spring device which is of simple construction and enables achieving high spring forces and long spring paths, it is proposed that the spring device comprises the following: a spring element which is able to be brought from an initial state into a deflected state by elastic deformation; an abutment element against which the spring element is able to abut for reaching a deflected state of the spring element, wherein at least one end of the spring element is moveable relative to the abutment element by elastic deformation of the spring element, wherein the spring element in the initial state thereof has an increasing distance from the abutment element in the direction of the end of the spring element which is moveable relative to the abutment element.
