Abstract

A component having a flat reinforcing element of a first stiffness and a flat material of a second stiffness. The first stiffness is higher than the second stiffness. The flat reinforcing element has a first end on a first narrow side. The flat material, on a second narrow side thereof, has a second end that bifurcates into two strips. The two strips of the second end enclose the first end on both sides in a zone of enclosure.

First claim

The invention claimed is:

1. A component comprising:
a flat reinforcing element of a first stiffness; and
a flat material of a second stiffness, the first stiffness being higher than the second stiffness, the flat reinforcing element having a first end on a first narrow side, and the flat material on a second narrow side having a second end that bifurcates into two strips, and the two strips of the second end enclosing the first end on both sides in a zone of enclosure,
wherein the flat material runs in an arc over an entirety of the zone of enclosure,
wherein a wall thickness of the flat material is at a maximum at a position at which the first narrow side of the flat reinforcing element meets the second end of the flat material,
wherein the wall thickness of the flat material increases continuously from a starting point of the arc to the position at which the first narrow side of the flat reinforcing element meets the second end of the flat material, and the wall thickness of the flat material decreases continuously from the position at which the first narrow side of the flat reinforcing element meets the second end of the flat material to an end of the arc.

2. The component according to claim 1 , wherein a maximum wall thickness of the flat reinforcing element is equal to or greater than half a wall thickness of the flat material outside the zone of enclosure.

3. The component according to claim 1 , wherein a length of a zone of overlap between the flat reinforcing element and the flat material is 1.5 to 8 times a wall thickness of the flat material.

4. The component according to claim 1 , wherein indentations are provided in at least one of the two strips on an end face thereof.

5. The component according to claim 4 , wherein the indentations are provided in both of the two strips.

6. The component according to claim 5 , wherein the indentations of a first strip of the two strips are arranged offset relative to the indentations of a second strip of the two strips.

7. The component according to claim 5 , wherein the indentations of a first strip of the two strips are arranged opposite the indentations of a second strip of the two strips.

8. The component according to claim 4 , wherein a length of all indentations is the same.

9. The component according to claim 4 , wherein in one strip of the two strips, there is a first group of indentations having a first length and a second group of indentations having a second length, and the first length is greater than the second length.

10. The component according to claim 9 , wherein the one strip is a first strip and the two strips includes a second strip, and
wherein the first group of indentations and the second group of indentations are present both in the first strip and in the second strip.

11. The component according to claim 10 , wherein the indentations of the second group in the first strip are opposite the indentations of the first group in the second strip, and
wherein the indentations of the first group in the first strip are opposite the indentations of the second group in the second strip.

12. The component according to claim 10 , wherein the indentations of the second group in the first strip are opposite the indentations of the second group in the second strip, and
wherein the indentations of the first group of indentations in the first strip are opposite the indentations of the first group in the second strip.

13. The component according to claim 1 , wherein the flat material is formed of:
an injection molded material of a thermoplastic type, or an extrusion molded material of a thermoplastic or a duroplastic type.

14. The component according to claim 1 , wherein the two strips of the flat material completely enclose:
an edge of the flat reinforcing element that contains an entirety of the first narrow side of the flat reinforcing element, or
only a partial region of the edge of the flat reinforcing element.
