Zusammenfassung:	PCT No. PCT/EP94/03303 Sec. 371 Date Apr. 10, 1996 Sec. 102(e) Date Apr. 10, 1996 PCT Filed Oct. 6, 1994 PCT Pub. No. WO95/11144 PCT Pub. Date Apr. 27, 1995The present invention deals with the problem of changing the design of the roof rails, which have hitherto been of a multipart design, in such a way that they can be manufactured in a simple manner and at a lower cost. This is achieved according to the present invention by the spar and the feet including one component, which is preferably formed by a deformed hollow chamber section. To achieve this, the hollow chamber section is deformed downward in a gentle arch at its end. The deformed bent section is cut off on the underside obliquely to the curved longitudinal axis of the section. The bottom of the hollow chamber section is then pressed in from below, so that an omega-shaped cross section is formed. The roof rail thus prepared has a consistently elegant shape, which does not reveal how it was made.
