Description

description

Frame arrangement for a vehicle roof and vehicle roof The invention relates to a frame arrangement for a vehicle

Vehicle roof and a vehicle roof with such

Frame arrangement.

DE 10 2007 057 999 B3 describes a vehicle roof, in which in a connection region between a

Guide rail and a frame member is arranged a sealing device. The sealing device is arranged in a recess which is formed in the joint area between the frame element and the guide rail. Above and below the sealing device, a bead of adhesive for fixing the guide rail and the frame member to the roof frame and a sealing profile are arranged, which cooperates in the closed position of a cover member with the underside thereof. According to DE 10 2007 057 999, the sealing profile and the adhesive bead are arranged directly above one another in the vertical direction. The

Sealing element extends in the vertical direction between the sealing profile and the adhesive bead. The end faces of the sealing device facing the sealing profile or the adhesive bead are completely covered by the sealing profile or the adhesive bead. Thus, one is

Sealing of the joint area possible if the adhesive bead and the sealing profile are arranged directly above one another.

It is desirable to have a frame assembly for a

Vehicle roof and to provide a vehicle roof, the

or which allows a secure sealing and has a low space requirement. According to one aspect of the invention, a frame assembly for a vehicle roof comprises a first frame member and a second frame member. The two frame members each extend longitudinally along a first direction. In a second direction, the frame members each extend between a first and a second major surface. The frame elements each have a transverse to the two main surfaces coupling side. The first and second frame members are on the coupling sides

Coupled with each other. The frame assembly has a first sealing area formed on the two first major surfaces to couple a first sealing member to the two frame members. The frame assembly has a second sealing area, which at the two second

Main surfaces is formed to couple a second sealing element with the two frame members. The first sealing region and the second sealing region are spaced apart in a third direction. The first direction, the second direction and the third direction are each aligned transversely to each other. The frame assembly has a

Frame seal on. At least one of the two

Coupling sides has a recessed area, whereby in a coupled state of the two

Frame elements a distance between the coupling sides is formed. The recessed area extends along the third direction from the first sealing area to the second sealing area. The frame seal is coupleable to the recessed area to provide, in the coupled state, the two frame members between the two

Seal sealing areas.

The two sealing areas are normal during operation

Alignment of the vehicle horizontally in the third direction spaced apart. Thus, the two sealing elements are not directly above one another in the vertical direction

arranged but offset from one another. The frame assembly is used in particular for coupling a lid to the vehicle roof. For example, the lid is movably coupled to the frame assembly relative to the vehicle roof. For this purpose, the frame arrangement has guide rails, at least in one of the frame elements, with which, for example, sliders and / or release mechanisms are coupled. In particular, when curved covers are to be used, which are curved in operation in a central region upwards, it is due to the staggered arrangement of

Sealing elements possible to save installation space. In particular, it is possible to save space along the second direction.

In operation, the second sealing area along the third direction, for example, further away from the center of the vehicle roof than the first sealing area. The first sealing area, for example, faces the lid. Thus it is

possible, the edge area of the lid closer to the

Provide frame elements, as in the outermost edge region between the lid and the frame elements no space for the sealing element must be provided. The sealing element is arranged horizontally offset inwards, where due to the curvature of the lid between the frame members and the lid more space is available. Overall, space is thus saved in the Z direction, in particular in comparison to an arrangement in which the first sealing element is arranged directly above the second sealing element.

The transition region between the two frame elements on the coupling sides must be in particular between the two Sealed sealing elements. For this purpose, the frame seal is placed in the recessed area. The frame seal extends between the two

Sealing elements elongated. In particular, the frame seal along the third direction has a greater extent than in each case along the first direction and the second direction. Thus, a reliable sealing is realized on the coupling sides. According to embodiments, the recessed region has a first overlap with the first sealing region and a second overlap with the second sealing region. Along the third direction, an intermediate region is arranged between the two overlaps. In particular, no overlap with one of the sealing regions is provided in the intermediate region. The overlap ensures a secure seal. About the intermediate area remains the

recessed area or in the

recessed area arranged frame seal also accessible during operation.

According to another aspect of the invention comprises

Vehicle roof a frame assembly according to at least one

Embodiment of the first aspect. The first

Frame member is coupled to the second frame member, so that the two coupling sides face each other. The first sealing element is coupled to the first and second frame members in the first sealing region. The second sealing element is coupled in the second sealing region with the first and the second frame member. The second

Sealing element has a bond to the two

Couple frame elements with a roof frame. The

Frame seal is in the recessed area between arranged on the two coupling sides and extending from the first sealing element to the second sealing element.

The vehicle roof has the frame assembly which is connected to the roof frame of the motor vehicle by means of the bond

connected is. The second sealing element is inside

arranged offset to the bond. Thus, it is possible to save space along the second direction, since the first sealing member is disposed in an area in which sufficient space is available. The space required immediately above or below the bond can thus be reduced. It must be immediately above the

Bonding no installation space for the first sealing element

be kept free.

According to embodiments, the frame seal is partially covered by the first sealing element on a first side and partially uncovered by the first sealing element. On a second side, which is opposite to the first side, the frame seal is partially covered by the second sealing element and partially uncovered by the second sealing element. By partially covering the frame seal with the first and the second sealing element is a

realized reliable sealing of the frame assembly or the vehicle roof. Due to the uncovered areas of the frame seal, it is possible the sealing elements

horizontally offset laterally to each other to arrange.

According to embodiments, the vehicle roof has a lid that is movable relative to the two frame elements. The cover is in particular part of a panoramic roof, a spoiler roof, a sunroof, for example one externally guided sunroof and / or a sliding roof, especially a top mountable roof (Top Load).

The first sealing element has a sealing profile to seal the two frame members and the lid in a closed position of the lid. Thus, in one

closed position of the lid by means of the sealing profile, the frame seal and the bonding a dry area of the vehicle roof separated from a wet area of the vehicle roof.

According to further embodiments, the vehicle roof alternatively or additionally has a relative to the two

Frame elements fixed lid. The first sealing element has a bond to couple the fixed lid with the two frame elements. By means of the two

Gluing and the frame seal is a dry area of the vehicle roof separated from a wet area of the vehicle roof. For example, the vehicle roof has both the movable lid and the fixed lid.

In particular, the fixed lid is disposed in operation in the closed position of the lid behind the movable lid. The movable lid can be moved rearwardly over the fixed lid to release a roof opening of the vehicle roof.

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

explained example. Same, similar and

like elements can be used with the same

Be provided with reference numerals. Show it:

FIG. 2 shows a schematic detail view of a frame arrangement according to embodiments,

Figure 3 is a schematic detail view of a frame assembly according to embodiments, and

Figure 4 is a schematic sectional view of a

Frame arrangement according to embodiments. FIG. 1 shows a vehicle roof 100. The vehicle roof 100 is provided, for example, for a motor vehicle and is inserted into a roof opening of the motor vehicle.

The vehicle roof 100 has a movable lid 128 and a fixed lid 130. The covers 128 and 130 are each coupled to a frame assembly 101. The fixed lid 130 is immovably coupled relative to the frame assembly 101. The movable lid 128 is relative to

Frame assembly 101 movable to be moved over or under the fixed lid 130, for example, and thus at least partially release the roof opening.

The frame assembly 101 includes a first frame member 102 and a second frame member 106. The first

Frame member 102 extends along the Y direction and is disposed in operation on a front side of the vehicle roof. The second frame member 106 extends along an X-direction and is in operation on the side of

Vehicle roof 100 arranged.

Figure 1 shows only one side of the vehicle roof 100. The second side is formed corresponding to the illustrated side.

The frame assembly 101 has another first

Frame member 135 which is disposed in operation on the rear side of the vehicle roof. The first one

Frame member 135 extends substantially along the Y direction.

For example, in the second frame member 106

Guide rails are designed to guide sliders, carriages and / or mechanisms that are provided for the movement of the movable lid 128.

FIG. 2 schematically shows a detail view of region 1 of FIG. 1.

The first frame member 102 has a first major surface 103 which is spanned by the X and Y directions.

A second major surface 104 is provided along the Z-direction, spaced from the first major surface 103. Transverse to the two main surfaces 103 and 104, a coupling side 105 is arranged, which is spanned by the Y and the Z direction. The second frame member 106 has correspondingly a first main surface 107 and a second main surface 108. A coupling side 109 of the second frame member 106 is aligned transversely to the two major surfaces 107 and 108. The two frame members 102 and 106 are coupled together so that the two coupling sides 105 and 109 face each other. For example, the two are

Frame members 102 and 106 coupled together by means of fastening tabs. There may be other elements as well

be provided to connect the two frame members 102 and 106 together. On the coupling side 105 of the first frame member 102, a recessed portion 116 is formed. The

Coupling side 105 has along the Y-direction first a projecting portion 121 thereafter the recessed portion 116 and then again the projecting portion 121 on. Correspondingly, the recessed portion 115 is formed on the coupling side 109 of the second frame member 106. Thus, the two coupling sides 105 and 109 at the recessed areas 115 and 116 are spaced by an amount 123. The two coupling sides 105 and 109 can also at the projecting portions 121

However, the amount 123 at the recessed areas 115 and 116 is greater than the distance at the protruding areas 121. According to further embodiments, only one of the recessed areas 115 and 116 is provided and the other coupling side has a straight course.

In the recessed areas 115 and 116 is a

Frame seal 114 is provided. The frame seal 114 is made of, for example, EPDM, butyl or other material which provides a seal against moisture and / or moisture. The frame seal 114 fills the recessed areas 115 and 116 so that along the coupling sides 105 and 109, neither in the Z direction nor in the Y direction, moisture or moisture can pass from a wet area 133 into a drying area 132. A capillary effect, moisture or moisture between the two coupling sides 109 of the wet region 133 in the

Drying area 132 would pull through the

Frame seal 114 interrupted.

An attachment of the frame assembly 101 to a roof frame 102 is realized by means of a bond 124. The

Adhesive 124 is a second sealing element 113, which at a second sealing portion 112 of the two frame members 102 and

106 is arranged. Along the second main surface 104 and the second main surface 108 seals the

Bonding 124, the coupling of the frame assembly 101 with the roof frame 125 against moisture and moisture.

On the first main surface 103 or the first main surface 107, a first sealing element 111 is arranged in a first sealing region 110. The first sealing element 111 has a sealing profile 129. The sealing profile 129 is designed to seal the lid 128 and the frame assembly 101 along the main surfaces 103 and 107 in a closed position of the lid 128.

The sealing areas 110 and 112 or the

Sealing elements 111 and 113 have along the Y-direction a distance 117 to each other. The distance 117 is the distance between the two mutually facing sides of the sealing elements 111 and 113th

The frame seal 114 has a first overlap 118 with the first sealing element 111. At the first overlap 118 For example, the frame seal 114 is covered by the first seal member 110 on a first side 126 of the frame seal 114. The first side 126 of the frame seal 114 runs

rectified to the major surfaces 103 and 107. Outside the first overlap 118, especially in one

Intermediate area 120 is the first side 126 of FIG

Frame seal 114 is not covered by the first sealing element 111 and freely accessible. The frame seal 114 is covered in a second overlap 119 by the second sealing element 113 on a second side 127. The second side 127 is arranged in the Z direction opposite to the first side 126 and extends rectilinearly to the second main surface 104 and to the second main surface 108.

Outside the second overlap 119 is the second side

127 of the frame seal 114 is not covered by the second sealing element 113 but freely accessible. Specifically, in the intermediate region 120 between the two overlaps 118 and 119, the frame seal 114 is in the Z direction of both

Pages freely accessible. In the intermediate region 120, according to the exemplary embodiment, both the first side 126 and the second side 127 are uncovered by one of the sealing elements 111 and 113. The frame seal 114 has an extent 122 along the Y-direction, which extends at least from the second

Sealing element 113 extends to the first sealing element 111. The extent 122 results at least from the second

Overlap 119, the distance 117 and the first overlap 118.

The centers of the two sealing elements 111 and 113 are spaced apart in the Y direction. For a reliable Sealing on the coupling sides 105 and 109, the elongated frame seal 114 is provided, which bridges the distance between the two sealing elements 111 and 113 in the Y direction. Water, which is present at the first main surfaces 103 and 107 in the wet region 133 on the first sealing element 111, can thus not reach the drying region 132 at the coupling sides 105 and 109 in the negative Z direction. Water which is present laterally in the area of the roof frame 125 on the second sealing element 113 and the frame elements 102 and 106 can not reach the drying area 132 in the Y direction on the coupling sides 105 and 109 from the wet area 133.

FIG. 3 shows a schematic detail view of the detail 2 of FIG. 1. The coupling of the first frame element 135 to the second frame element 106 essentially corresponds to the coupling of the first frame element 102 to the second one

Frame member 106 as explained in connection with Figures 1 and 2. In contrast, the first sealing element 111 is a bond 131, which fixes the fixed cover 130 with the two frame elements 135 and 106. Instead of

Sealing profile 129, the bond 131 is provided. The further features and advantages in particular of the arrangement of the frame seal 114 with the overlapping areas 118 and 119 as well as the intermediate area 120 corresponds to the one explained in connection with FIG.

Figure 4 shows a schematic sectional view through the frame assembly 101 in the region of the frame seal 114. The mutually facing sides of the two sealing elements 111 and 113 have the distance 117 to each other. The sealing element 111 has the overlap 118 with the frame seal 114. The sealing element 113 has the overlap 119 with the Frame seal 114 on. The overlaps 118 and 119 each have at least the amount 123 according to embodiments. The overlaps 118 and 119 may be the same size, but they may be different in size. The

Frame seal overlaps with the sealing elements 111 and 113 at least as far as the extent of the frame seal 114 in the X direction. As a result, a secure seal is possible. For example, the overlap 118 is significantly larger than the overlap 119. In particular

production reasons, since the slot in the

recessed area 115, 116 between the coupling sides 105 and 109 is ejected with a tool. Here the injection point or overflow can be without the

Function of the planar, smooth surfaces on the main surfaces 103 and 107 and 104 and 108 to endanger.

By the distance 117 in the Y direction between the sealing element 111 on the main surfaces 103 and 107 and the sealing element 113 on the main surfaces 104 and 108, it is possible to

to reduce required space in the Z direction. The distance 117 is in particular depending on a curvature of the

Cover 128 and the lid 130 given. The distance 117 is in particular greater, the stronger the cover 128 or 130 is curved. By the

reset areas 115 and 116 is a slot

formed by the extending in the Y direction

Frame seal 114 is filled. The extent 122 of the frame seal 114 in the Y direction is dependent on the distance 117 between the two sealing elements 111 and 113, as well as the overlaps 118 and 119. Due to the size of the

recessed areas 115 and 116, which are in particular larger than in sealing elements which are arranged directly above one another in the Z-direction, is a production with a lower susceptibility to errors possible because larger tolerances in the production are possible. A slight ejection of the gap between the two frame members 102 and 106 in the recessed areas 115, 116 is possible.
