Patent ID: 7841063

Claim:
A method for the production of a deformable element of a steering spindle for a motor vehicle, which deformable element is formed as a corrugated tube provided with openings penetrating a wall of the corrugated tube, said method comprising: forming from flat sheet metal at least two subshells extending in a longitudinal direction, the subshells having corrugations oriented transversely to their longitudinal direction, wherein the subshells are disposed longitudinally next to one another in a single common sheet metal part or are separate parts, wherein: in the case of a formation of the at least two subshells disposed in the common sheet metal part next to one another, folding or curving a preformed sheet metal part in a region between the at least two subshells about an axis parallel to a longitudinal direction of the subshells, and bringing free longitudinal edges of the subshells into mutual contact so as to be connected with one another, and in the case of a formation of the at least two subshells in the form of separate parts, placing the separate subshells adjacent to each other with their longitudinal edges connected with one another, and wherein in the step of connection of the longitudinal edges, at least one of the two longitudinal edges of the subshells coming into mutual contact is provided with a row of cutouts spaced apart from one another in the longitudinal direction of the subshells, and through the connection of sections of the one of the longitudinal edges located between the cutouts with the other longitudinal edge, in a connection region of the two longitudinal edges, a number of openings spaced apart in the longitudinal direction of the corrugated tube are formed through the wall of the corrugated tube.
