Abstract: A spring for use in conjunction with a vehicle, in particular a leaf spring (1), preferably a parabolic spring, has a single-part spring leaf (12) made of steel, in particular spring steel, having a central region (2) and two adjoining edge regions (4a, 4b), wherein the edge regions (4a, 4b) each have an end region (5a, 5b), the end regions (5a, 5b) can each be connected to a chassis in a stationary manner via a rolled eye (11), and the total length of the spring when installed on the vehicle is substantially unchangeable in all load states. In the unloaded state, the spring leaf (12) has two bending sections (13, 14), which each have a curvature with a curvature direction, wherein the curvature directions of the two bending sections (13, 14) are opposed, and the two bending sections (13, 14) merge into each other in the region of a turning point (15).

Abstract: A spring, in particular a flat spring (5), for use in connection with a vehicle, has a middle region (6) which has a curve with a first curve direction, as well as two edge regions (7). In an unladen state, the edge regions (7) each have a curve with a second curve direction and vertices (10), with the second direction of curve being opposed to the first direction of curve. The flat spring (5) has a vertex axis (11) running through the vertices (10) of the curves of the edge regions (7). End regions (8) of the edge regions (7) are tilted away from the vertex axis (11) toward the side of the vertex axis (11) on which the middle region (6) lies.

Abstract: A spring, in particular a flat spring (1), for use in connection with a vehicle, has a middle region (2), with the middle region (2) featuring a central axis (3), as well as two edge regions (4), with the edge regions (4) each having an end region (5). In an unladen state, at least one edge region (4) adjacent to the middle region (2) has a first curve region (6) with a first curve direction and a first vertex (7), with the first vertex (7) lying on one side of the central axis (3). Toward its end region (5), this edge region (4) has a second curve region (8) with a second curve direction and a second vertex (9), with the second curve direction opposed to the first curve direction and with the second vertex (9) lying on the opposite side of the central axis (3) to the first vertex (7).
