Bend of a metal sheet, preferably in the visually relevant exterior region of a vehicle

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.

Claims

A component movably arranged with respect to another component so as not to collide with the another component, the component comprising: a metal sheet to be movable along with the component, wherein the metal sheet is configured as an exterior visible region of a vehicle, the metal sheet has a bend with a smooth, harmonic mathematical curve of a third degree which is composed of two arcuate segments having an identical radius and a flattened area in an interjacent region, and the bend is collision-free with the another component during an entire movable motion of the component.

2. The component according to claim 1, wherein the flattened area in the interjacent region has a radius greater than the radius of the two arcuate segments.

3. The component according to claim 1, wherein the flattened area in the interjacent region is designed as a planar chamfer.

9. A vehicular door to be pivotably movable and arranged so as not to collide with an adjacent door when assembled in a vehicle, the vehicular door comprising: a metal sheet to be movable along with the vehicular door, wherein the metal sheet has a bend with a smooth, harmonic mathematical curve of a third degree which is composed of two arcuate segments having an identical radius and a flattened area in an interjacent region, and the bend is collision-free with the adjacent door during an entire pivotable motion of the vehicular door.

10. A component to be movably arranged with respect to another component so as not to collide with the another component, the component comprising: a metal sheet to be movable along with the component, wherein the metal sheet is configured as an exterior visible region of a vehicle, the metal sheet has a bend with a smooth, harmonic mathematical curve of a third degree which is symmetrical, and the bend is collision-free with the another component during an entire movable motion of the component.

11. The component according to claim 10, wherein the mathematical curve of the third degree is a spline curve.

Description

BRIEF DESCRIPTION OF THE DRAWINGS

(1) FIG. 1 is a side view of a vehicle;

(2) FIG. 2 is a schematic representation of a door of a vehicle;

(3) FIG. 3 is a sectional illustration in the region between two doors of the vehicle; and

(4) FIG. 4 is an enlarged representation of a portion of detail X of FIG. 2.

DETAILED DESCRIPTION OF THE DRAWINGS

(5) The figures show the invention by way of example in the region of a door 1 of a vehicle which adjoins a vehicle part or another door 2. However, the described embodiment can also be provided on another movable or pivotable vehicle part, such as a lid or the like.

(6) The door 1 is provided with a door hinge 1a and is pivotable about a pin 1b in such a way that the door 1 moves on a circle of rotation 1c.

(7) At the edge pointing to a fixed vehicle part or another door 2, the metal sheet of the door 1 is provided with a bend 3, which according to the invention has the shape shown in FIG. 4.

(8) The bend 3 is no longer designed as a radiusas in the related art and shown in FIG. 4 as a dotted linebut as a spline, also referred to as a polynomial curve, and therefore has the shape of a smooth, harmonic, assembled mathematical curve of the third degree.

(9) The curve of the third degree or the spline or polynomial curve is advantageously composed of two arcuate segments 4 and a flattened area 5 in the interjacent region.

(10) In the exemplary embodiment shown, the radii of the arcuate segments 4 have the same size; however, they can also have different sizes.

(11) The flattened area 4 located between the arcuate segments 4 has a radius that is greater than the radius of the arcuate segments 4.

(12) The flattened area 5 canas shownalso be designed as a planar chamfer, which transitions into the arcuate segments 4.

(13) The radius of the arcuate segments 4 is in the low single-digit millimeter range and is preferably 1.5 mm.
