## Abstract

A method for tensioning shaped parts, with a frame and a plurality of tensioning elements which are formed by a holding part and a clamping part. The holding part abuts the shaped part pointwise and a clamping part pushes the shaped part in the direction of the surface normal against the holding part.

## Claims

### Claim 1

A method of clamping a shaped body part for a motor vehicle at a single contact point on said shaped part, said method comprising the acts of:
providing a tensioning device including a frame and a plurality of tensioning elements mounted on said frame, each of said tensioning elements having a holding part and a clamping element that presses the shaped part against the holding part, each of said holding part and said clamping element having a convex clamping surface for pointwise engagement with said shaped part at said contact point; and
clamping said shaped part between said clamping element and said holding part of each of said tensioning elements, such that said clamping element presses the shaped part against the holding part.

### Claim 2 (depends on 1)

The method according to claim 1, wherein said holding part and said clamping element are arranged such that a clamping force therebetween is directed normal to a surface of said shaped part.

### Claim 3 (depends on 1)

A method according to claim 1, wherein said pointwise engagement by said convex clamping surfaces of said holding part and said clamping element secures the shaped part in only one dimension.
