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.
