Roof rack for a motor vehicle
The invention relates to a roof rack roof rack for a motor vehicle, having a roof rail profile. The roof rail profile is manufactured from a profile that has a constant cross-section in the longitudinal direction of the profile. Roof rail profiles with different designs can be formed from one and the same profile cross-section, namely by the shaping of a side or wall section present on the profile that delimits a passage. The roof rail profile, which preferably is designed as one piece, has different cross-sections in the longitudinal direction, namely unshaped surface sections and shaped surface sections.
1. A roof rack for a motor vehicle, the motor vehicle having a roof contour, the motor vehicle having an outside, the roof rack made of a roof rail profile ( 10 ) that has at least a top ( 14 ) and two lateral surfaces ( 15 , 16 ), the roof rail profile having a longitudinal direction, wherein the roof rail profile ( 10 ) has different cross-sections in the longitudinal direction,
in that the roof rail profile ( 10 ) has a bottom ( 11 ) which rests on the roof contour of the motor vehicle,
in that the roof rail profile ( 10 ) is made from an extruded profile or from a roll-formed profile, which has been matched to the roof contour of the motor vehicle by stretch-bending,
characterized in that
the first lateral surface ( 15 ) facing the outside of the vehicle has, in the longitudinal direction of the roof rail profile ( 10 ), first surface sections ( 17 , 17 ′, 19 ) and shaped second surface sections ( 18 ),
in which the first surface sections ( 17 , 17 ′, 19 ) provided at the front end ( 12 ) and at the back end ( 13 ) of the roof rail profile ( 10 ), and have the form of railing feet,
in which the second surface sections ( 18 ) have been produced by rolling, pressing, stamping, or impressing after the stretch-bending,
wherein the roof rail profile ( 10 ) has different cross-sections in the longitudinal direction by the first surface sections ( 17 , 17 ′, 19 ) and the shaped second surface sections ( 18 ),
and in that the roof rail profile ( 10 ) has, in the region of the first surface sections ( 17 , 17 ′, 19 ), next to the first lateral surface ( 15 ), an open or closed passage ( 21 ) that is delimited by at least a first side ( 20 ) or wall section ( 20 ′) running along the lateral surface ( 15 ), and wherein the shaped surface sections ( 18 ) are formed by a shaping force acting from the outside on this side ( 20 ) or wall section ( 20 ′).
2. The roof rack according to claim 1 , wherein the roof rail profile has a central area, the roof rack characterized in that another unshaped surface section ( 19 ) that has the form of a center foot is provided in the central area of the roof rail profile ( 10 ).
3. The roof rack according to claim 1 , characterized in that the shaped surface sections contain patterns, inscriptions, or logos.
4. The roof rack according to claim 1 , characterized in that the profile is extruded, wherein the profile has an open passage ( 21 ) running in the longitudinal direction of the profile that is formed on the one hand by the first side ( 20 ) extending along the lateral surface ( 15 ) and on the other hand by a second side ( 22 ) that delimits a closed or open hollow profile chamber ( 23 , 24 ) of the extruded profile, wherein the second side ( 22 ) is not additionally shaped.
5. The roof rack according to claim 4 , characterized in that the passage ( 21 ) running in the longitudinal direction of the roof rail profile ( 10 ) is U-shaped and is open downward in the region of the first surface sections.
6. The roof rack according to claim 1 , characterized in that the shaped surface sections ( 18 ) of the lateral surface ( 15 ) are produced by rolling, pressing, stamping, or impressing sections of the freely shapeable first side ( 20 ) or of the shapeable wall section ( 20 ′) toward the passage ( 21 ).
7. The roof rack according to claim 1 , characterized in that the first side ( 20 ) extends to a bottom ( 11 ) of the roof rail profile ( 10 ).
8. The roof rack according to claim 1 , characterized in that the first side ( 20 ) extends within a center region with respect to the height of the lateral surface ( 15 ).
9. The roof rack according to claim 1 , characterized in that a free end of the first side extends toward a bottom ( 11 ).
10. The roof rack according to claim 1 wherein the roof rail profile has sidewalls, characterized in that the open or closed passage ( 21 ) is a closed passage running in the longitudinal direction of the roof rail profile ( 10 ) is covered by the wall section ( 20 ′) that has a smaller wall thickness (D) than the sidewalls of the roof rail profile ( 10 ).
11. The roof rack according to claim 10 , characterized in that the wall section ( 20 ′) that delimits the passage ( 21 ) from the outside has a wall weakening ( 29 ) on its inside that facilitates the forming.
12. The roof rack according to claim 10 , characterized in that the wall section ( 20 ′) is provided on its outside with a surface texturing ( 30 ).
13. The roof rack according to claim 12 where the surface texturing is a corrugation introduced by extrusion.
14. The roof rack according to claim 1 , characterized in that the roof rail profile ( 10 ) is made of aluminum, of an aluminum alloy, or of stainless steel.
