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). The first bending section (13) is a vertical spring section and runs from the end region (5a) of the first edge region (4a) via the central region (2) to the turning point (15). The second bending section (14) is a horizontal and vertical spring section and runs from the turning point (15) to the end region (5b) of the second edge region (4b).

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
