A segment 1 of an aerodynamic body has as the internal actuating drive an actuator 7, which acts on an upper profile shell 2 with one working piston 9 and on a lower profile shell with a working piston 8 acting in the opposite direction to generate oppositely directed arches of the segment 1. The profile shells 2 and 3 are mounted displaceably in relation to one another in dovetail guides 4 and 5.

An ergonomically shaped exterior contour of a vehicle interior handle area, support area, or resting area is provided. The contour is formed by a flexible shaped element filled with an electro-rheologic fluid to which an electrical circuit operable from the interior is connected to reduce or increase the internal friction of the fluid to accommodate changes in shape of the contour.

The piezoelectric actuator consists of at least two disk-shaped congruent bending elements which each have a carrier plate made of a hard-elastic material with a layer of a piezoelectric material applied to one or both sides. Two bending elements respectively are connected with one another by way of at least two bending joints arranged on the circumference of the carrier plates.
