Abstract

The present invention relates to a bend of a sheet, preferably in a visually relevant exterior region of a vehicle. In order to provide a bend which enables the separating point between moving and fixed parts to have a visually narrower effect and impart a higher-quality appearance of the entire vehicle, it is provided that the bend is designed in the form of a smooth, harmonic, assembled mathematical curve of the third degree.

First claim

What is claimed is:

1 . A component, comprising:
a metal sheet, wherein the metal sheet has a bend with a smooth, harmonic mathematical curve of a third degree.

2 . The component according to claim 1 , wherein the mathematical curve of the third degree is composed of two arcuate segments and a flattened area in an interjacent region.

3 . The component according to claim 2 , wherein radii of the two arcuate segments have a same size.

4 . The component according to claim 2 , wherein radii of the two arcuate segments have different sizes.

5 . The component according to claim 2 , wherein the flattened area in the interjacent region has a radius greater than a radius of the two arcuate segments.

6 . The component according to claim 3 , wherein the flattened area in the interjacent region has a radius greater than a radius of the two arcuate segments.

7 . The component according to claim 4 , wherein the flattened area in the interjacent region has a radius greater than a radius of the two arcuate segments.

8 . The component according to claim 2 , wherein the flattened area in the interjacent region is designed as a planar chamfer.

9 . The component according to claim 3 , wherein the flattened area in the interjacent region is designed as a planar chamfer.

10 . The component according to claim 4 , wherein the flattened area in the interjacent region is designed as a planar chamfer.

11 . The metal sheet component according to claim 2 , wherein the radii of the two arcuate segments are in a low single-digit millimeter range.

12 . The metal sheet component according to claim 2 , wherein the radii of the two arcuate segments are 1.5 mm.

13 . The metal sheet component according to claim 3 , wherein the radii of the two arcuate segments are in a low single-digit millimeter range.

14 . The metal sheet component according to claim 13 , wherein the radii of the two arcuate segments are 1.5 mm

15 . The metal sheet component according to claim 1 , wherein the mathematical curve of the third degree is a spline curve.

16 . The metal sheet component according to claim 1 , wherein the mathematical curve of the third degree is a polynomial curve.

17 . The metal sheet component according to claim 1 , wherein the metal sheet is configured as an exterior visible region of a vehicle.
