Abstract
A flat shaped spring may include a spring element. The spring element may have, in a longitudinal section along a central longitudinal axis extending along an axial direction, two profile halves disposed on opposite sides of the central longitudinal axis. The two profile halves may each have a first profile portion and a second profile portion. The first profile portion may have a curvature opposed to the second profile portion. Two outer ends of the spring element facing away from the central longitudinal axis, and which lie opposite one another in a longitudinal direction extending perpendicularly to the axial direction, may be connected to one another via at least one connection element such that the spring element and the at least one connection element collectively form a closed profile in the longitudinal section.
