Method for producing a roof rail, extruded profile therefor and roof railing for a vehicle

1 . Method for producing a roof rack ( 10 , 10 ′) comprising the steps:

producing an extruded profile section from aluminum, consisting of a tubular profile part with a hollow space ( 6 ) enclosed by profile walls ( 2 , 3 , 4 , 5 ) and additionally consisting of at least one profile web ( 7 , 7 ′) that is connected at one end to the tubular profile part and faces downward with its other, free end ( 8 ),

cutting extruded profiles ( 1 ) of a desired length from the extruded profile section ( 1 ),

creating a desired lateral contour line ( 9 ) on the roof rack ( 10 , 10 ′) by machining of the profile webs ( 7 , 7 ′) that are present.

2 . Method according to claim 1 , characterized in that an extruded profile section is produced in which two profile webs ( 7 ) are present, each of which constitutes an extension of the lateral profile wall ( 3 , 4 ).

3 . Method according to claim 1 , characterized in that an extruded profile section is produced in which a profile web ( 7 ′) is located in front of a lateral profile wall ( 4 ), and if applicable a second profile web ( 7 , 7 ′) is present that constitutes an extension of an additional lateral profile wall ( 3 ).

4 . Method according to claim 3 , characterized in that an extruded profile section is produced in which the profile web ( 7 ′) in front of the lateral profile wall ( 4 ) forms, with this profile wall ( 4 ), a groove ( 8 ) that is open toward the bottom.

5 . Method according to claim 2 , characterized in that an extruded profile section is produced in which a passage ( 15 ) extending in the longitudinal direction of the profile and open toward the outside is located on the lateral profile wall ( 4 ).

6 . Method according to claim 1 , characterized in that the extruded profile ( 1 ) is bent before or after the machining in order to match a specified roof contour of a motor vehicle.

7 . Method according to claim 6 , characterized in that the contact surface of a surface-mounted roof rack ( 10 ′) is additionally created by means of the machining, or the support surfaces of the feet of a two-footed roof rack ( 10 ) or a three-footed roof rack are additionally created by means of the machining.

8 . Method according to claim 6 , characterized in that the machining is performed by milling, stamping, water-jet cutting, or laser machining.

9 . Method according to claim 1 , characterized in that a lateral contour that constitutes a receptacle is created on the roof rack ( 10 , 10 ′) by the machining, and an insert ( 40 ) of the same or a different color is subsequently inserted into the receptacle and attached to the roof rack ( 10 , 10 ′).

10 . Method according to claim 1 , characterized in that a lateral contour line that includes a center foot is created on the roof rack ( 10 , 10 ′) by the machining.

11 . Roof rack for motor vehicles, consisting of a rail ( 13 ) and end feet ( 11 , 12 ) that can be attached to a motor vehicle roof, wherein the rail ( 13 ) and the feet ( 11 , 12 ) are designed as a single piece and are made from an extruded profile ( 1 ) of aluminum according to one of claims 1 to 8 , wherein the rail ( 13 ) is composed of a tubular profile part of the extruded profile ( 1 ), wherein the end feet ( 11 , 12 ) are composed of a bend section of the tubular profile part, wherein the rail ( 13 ) has different cross-sections in the longitudinal direction, characterized in that the different cross-sections are created by machining of at least one additional profile web ( 7 , 7 ′) on the extruded profile ( 1 ), and wherein a freely selectable lateral contour line is formed by the machined profile web ( 7 , 7 ′).

12 . Roof rack according to claim 11 , characterized in that the rail ( 13 ) and the feet ( 11 , 12 ) constitute a surface-mounted roof rack ( 10 ).

13 . Roof rack according to claim 11 , characterized in that the feet ( 11 , 12 ) and the rail ( 13 ) constitute a roof rack ( 10 ′) raised on fixed supports.

14 . Roof rack according to claim 11 , characterized in that the rail ( 13 ) has a passage ( 15 ) extending in the longitudinal direction of the profile for a lighting element ( 30 ), and this passage ( 15 ) terminates in the end feet ( 11 , 12 ), and components for activating the lighting element ( 30 ) are accommodated in a hollow space in the feet ( 11 , 12 ), wherein the connection point of the lighting element ( 30 ) with the components for activation is covered by the profile web ( 7 , 7 ′).
