Frame arrangement and system for a vehicle roof as well

Method for producing a guide rail

The invention relates to a frame assembly for a

A vehicle roof having a water guiding area, and a system for a vehicle roof having such a frame arrangement. The invention further relates to a method for producing a guide rail for a vehicle roof.

Roofs of vehicles, in particular motor vehicles, may be provided with a sunroof. A lid can be a roof opening either in a closed position of the

Close lids or at least partially release them in other positions. Water that penetrates between the lid and the vehicle roof inside the vehicle, is from a

Collected water flow and derived controlled. DE 10 2010 054 590 B3, for example, shows a frame of an openable vehicle roof. The frame has lateral frame parts, each having a water channel to

Have water.

It is desirable to have a frame assembly for a

Specify vehicle roof and a system for a vehicle roof, which allows a reliable water supply. In addition, it is desirable to provide a method of manufacturing a guide rail for a vehicle roof

indicate that the cost-effective production of the

Guide rail with a water guide allows.

In accordance with at least one embodiment of the invention, a frame arrangement for a vehicle roof has a Guide rail for guiding a movement of a roof element. The frame assembly includes a frame member, wherein the guide rail and the frame member are coupled together at a respective end. Either the guide rail or the frame member or both the guide rail and the frame member has or have an end portion which directly to the respective end

followed. The end region has a first cross-section, which extends from a second cross-section outside the

Deviates end range. As a result, a supply line to a water supply region of the frame assembly is formed.

In the end area where the guide rail and the

Frame member are coupled together, another cross section of the guide rail and / or the frame member is provided as outside the end portion. Thus, it is possible to flexibly adapt the supply line to the water supply area to installation specifications for the frame arrangement.

In particular, it is possible to supply the lead to the

Depending on the roof element, adapt the water supply area so that water reliably flows into the building during operation

Water guidance area is passed between the

Roof element and the vehicle roof in the direction of

Vehicle interior penetrates.

By way of the first cross section and the feed line formed thereby, it is possible, for example, for the roof element to have an outer shape deviating from the water guide region. Without the supply line, water that penetrates between the roof element and the vehicle roof would be able to enter the vehicle in an uncontrolled manner. By means of the supply line, however, this water is collected and controlled to Guided water supply and derived below. The water does not get into the particular

Passenger compartment of the vehicle. The supply line is by means of the first cross section as an integral part of

Implemented guide rail and / or the frame member and thus without additional components.

According to embodiments, the end region has a

projecting area, which forms the supply line. The projecting region protrudes in the Y-direction or in the negative Y-direction, in particular in the mounted state in the normal operating position of the vehicle. Thus, a deviation of the outer shape of the roof element in the Y direction of the water guide area is possible.

The end region of the frame element and / or the end region of the guide rail is in particular formed in one piece.

For example, the guide rail is a metal profile. The first cross-section is made in one piece by forming the metal profile. For example, the

original shape of the metal profile on the second cross section. In the end region of the cross section of the metal profile is changed by the forming to the first cross section.

Thus, it is possible without additional components to adapt the supply line to the water supply area to the roof element.

According to embodiments, the frame element is a

Plastic moldings. For example, the first one is

Cross-section formed as part of the plastic molding. The plastic molding is manufactured so that it is in

End portion has the first cross section to form the supply line to the water guide area. Thus, the Supply to the water supply area without additional

Components possible.

According to a further aspect of the invention, a system for a vehicle roof has a frame arrangement according to at least one explained embodiment. The system further comprises the roof element. The roof element has a front edge and a side edge aligned transversely thereto. The roof element is at the side edge with the

Coupled guide rail. The leading edge extends at least partially along the frame element. The guide rail at least partially forms the water guide area. At least in a closed position of the roof element, the side edge extends outside of the end region along the

Water management area. In the end region, the course of the water-guiding region and the course of the side edge deviate from one another. In the closed position of the roof element, the roof element closes the roof opening. The roof element has a curved lateral edge in plan view. The guide rail and in particular the

Water supply area are straight. Thus, the side edge in the end region is relative to

Water supply area not arranged so that penetrating water enters directly into the water supply area. In the end region, therefore, the feed line is formed to offset the offset between the side edge and the

Balance water supply area. For example, the water guide region has a linear course and the side edge has a curved course, at least in an end region which adjoins directly to the front edge. The first cross section of the Supply line forms, is formed so that it corresponds to the curvature of the side edge and thereby in

Operation reliably water, which penetrates from the side edge into the vehicle interior, leads to the water guidance area.

According to a further aspect of the invention, a

Method for producing a guide rail for a

Vehicle roof providing a metal profile in an original state. A side wall of the metal profile is in an end region, which is directly at one end of

Metal profile connects, reshaped. This will be a

Feed line formed to a water supply area, in particular to a water supply area of the

Metal profile. Thus it is possible without additional

Components to produce a lead to the metal profile.

Further advantages, features and developments will become apparent from the following, in conjunction with the figures

explained examples.

FIG. 3 shows a schematic illustration of a detail of an embodiment of the vehicle roof,

FIG. 4 shows a schematic representation of a cross section of a guide rail, Figure 5 is a schematic representation of a sectional view of an embodiment of the vehicle roof, and Figure 6 is a schematic representation of a sectional view of an embodiment of the vehicle roof.

In the exemplary embodiments and figures, identical, identical or identically acting elements can each be provided with the same reference numerals.

FIG. 1 shows a vehicle 100, in particular a

Motor vehicle. The vehicle 100 has a vehicle roof 101. In the normal operating position in front a windshield 121 is arranged. In the X-direction behind is a rear window

(not explicitly shown) arranged. The vehicle roof 101 extends in particular between the windscreen 121 and the rear window. The vehicle roof 101 has a roof opening 123. The roof opening 123 can be closed by a roof element 104. By a movement of the roof element 104 relative to the rest of the vehicle roof 101, the roof opening 123 is at least partially releasable. The roof element 104 is, for example, part of a panoramic roof, a spoiler roof, a sunroof, for example, an externally guided

Sliding roof and / or a sliding roof, a top-mountable roof or one from below

mountable roof (bottom load). The roof element 104 is also called cover and is for example made of glass or a transparent plastic.

The roof element 104 has one of the windscreen 121

facing front edge 115. In the X direction close on both sides of the roof element 104 to the front edge 115th Side edges 116 and 117 on. Facing the rear window or on the side facing away from the front edge 115, the roof element 104 has a rear edge 118. FIG. 2 shows the vehicle roof 101 with a system 120. The system 120 has the roof element 104 and a

Frame assembly 102 on. By means of the frame assembly 102, it is possible to couple the roof element 104 with the vehicle roof 101. Figure 2 shows the closed position in which the

Roof element 104, the roof opening 123 closes.

The frame assembly 102 has two guide rails 103 which, in operation, are each elongate in the X direction on the sides of the roof opening 123. The

Frame assembly 102 also includes a frame member 105 which extends longitudinally in the Y direction and is disposed on the side of the roof opening 123 facing the windshield 120. In a region of the side edges 116 and 117, the roof element in each case has a cover carrier (not explicitly shown) which is coupled to a mechanism for controlling the movement of the roof element 104 relative to the rest of the vehicle roof 101. The mechanism is also coupled to the respective guide rails 103, so that the roof element 104 is coupled to the frame assembly 102.

Hereinafter, a guide rail 103 will be explained. However, the second guide rail 103 is formed correspondingly, so that the explanations are also valid for the second guide rail 103. The guide rail 103 has an end 106 facing the front screen 121. The frame member 105 has an end 107 which is coupled to the end 106 of the guide rail 103.

The guide rail 103 has a linear course in the X direction. The side edges 116 and 117 of the roof element 104 each have a curved course along the X direction. Thus, it is possible to change the width of the

Roof element 104 in one of the windscreen 121 facing area form larger than in a rear window facing area. The front edge 115 of the roof element 104 is longer than the rear edge 118. FIG. 3 shows a schematic detail of a front region of the vehicle roof 101.

In an end region 108 of the guide rail 103

or of the frame element 105, the course of the side edge 117 deviates from the course of the guide rail 103 or of the frame element 105. In a region 111 outside the end region 108, which lies in the X direction behind the end region 108, the profile of the guide rail 103 overlaps with the profile of the side edge 117.

Along the side edges 116, 117 immediately adjacent to the front edge 115 in each case an end portion 119 at. The course of the side edges 116, 117 in the end region 119 of FIG

Side edges 116, 117 respectively deviate from the course of the water guide region 113, in particular in the

Closed position. In the guide rail 103 and in the frame assembly 102, a water guide portion 113 is formed. Water that passes between the roof member 104 and the rest of the vehicle roof 101 inside the vehicle 100 is of the

Water management area 113 collected and derived controlled. In the area 111, the side edge 117 extends in a plan directly above the water guide area 113, so that the water from the side edge 117 directly into the

Water supply area 113 passes. In the end region 108, the side edge 117, or the front edge 115, does not extend directly above the end view

Water management area 113.

The mechanism for moving the roof member 104, according to embodiments, requires a substantially linear motion.

Therefore, the guide rails 103 are linear. The

Side edges 116 and 117, however, are curved at least in the end region 108, so that the deviation of the side edges 116 and 117 from the water guide region 113 arises.

FIG. 4 shows a cross section of a guide rail 103. The guide rail has a side wall 124. The portion of the sidewall 124 that extends in the Z direction and another sidewall 125 that extends in the Z direction

extends, together with the bottom 126 of the

Guide rail 103, the water guide area 113th Die

Guide rail 103 has in particular over its full length in the X direction, the side wall 124 which the

Water management serves.

FIG. 5 shows a schematic representation of the section AA of FIG. 3. In the Y direction between the roof element 104, in particular the side edge 117, and the remaining vehicle roof 101, a seal 122 is arranged. In operation, however, it happens that water between the side edge 117 and the rest of the roof 101 despite the seal 122 in the direction of the guide rail 103 passes.

In the end region 108, the cross section of which is shown in FIG. 5, the vehicle edge 117 does not extend directly above the water-guiding region 113. In order to be able to guide the water in a controlled manner to the water region 113, this is

Guide rail 103 starting from that in Figure 4

shown cross section deformed to a first cross section 109. In particular, the side wall 124 is deformed in the Y direction, so that a Y-direction projecting portion 114 is formed. Thus, a supply line 112 to the water supply region 113 is realized. The sidewall 124 is reshaped to extend at least to below the side edge 117 in the Y direction. The reshaped

Side wall 124 forms the supply line 112. The

The guide rail 103 thereby has, in the end region 108, the first cross section 109, which has the water guide region 113 and the region 114 projecting in the Y direction. By means of the projecting portion 114, water from the curved side edge 117 in the linear

Water guide area 113 out.

In the illustrated sectional view of Figure 5 is the

Water guide portion 113 of the frame member 105 shown. In the X direction further back in the end region 108 is the

Water guide portion 113 of the guide rail 103rd

educated . The side wall 124 is deformed so that it in

Coupling region of the frame member 105 with the

Guide rail 103, which is shown in Figure 5,

is arranged at least below the side edge 117.

In particular, in the end region 108, the guide rail 103 and the side wall 124 are formed by means of a trimming process and / or a forming process starting from the

Cross-section, which is shown in Figure 4, shaped so that the penetrating water in the water guide portion 113 of the guide rail 103 and / or the water guide portion 113 of the front frame member 105 is derived. By doing

End portion 108 allows the deformed guide rail 103 with the first cross section 109 at a given

Glass lid shape with curved side edges 116 and 117 a reliable water management without additional parts.

Figure 6 shows a schematic representation of the section BB of Figure 3. In the area 111, the side edge 117 extends in the X direction directly above the water guide portion 113 of the guide rail 103. Thus, even with a second

Cross section 110 of the guide rail 103, which differs from the first cross section 109, a reliable

Water management possible. In particular, in the second cross section 110, the side wall 124 is compared to

original state, which is shown in Figure 4, not deformed. It is possible that a region of sidewall 104 extending in Y has been removed which is not required for the support of seal 122 in region 111.

By forming the side wall 124 in the end region 108, a reliable supply of penetrating water into the water guide region 113 is also in the case of a non-linear course the side edges 116 and 117 of the roof element 104 possible. A non-linear course of the side edges of the roof opening 123 in the X direction is possible. Thus, a maximum

Transparent width through the roof opening 123 possible. It is possible to form the side edges 116 and 117 so that they run parallel to the roof track of the side rails. In addition, it is possible to realize the corner radii with a minimum size. In this case, due to the deformed first cross-section 109, a reliable drainage of penetrating water without additional parts is possible. In addition, a linear movement in the X direction of the mechanism for controlling the

Movement of the roof element 104 possible.
