Description

The present invention relates to a vehicle roof system according to the preamble of claim 1.

A generic vehicle roof system has a movable cover for selectively opening and closing a roof opening in a vehicle roof. A slider is arranged on the lid, by means of which the lid can slide relative to a wind deflector and into contact with it and can move the wind deflector downwards when the lid transitions into a closed position. The glider has a hammer foot, by means of which the glider is fixed in a groove on the lid. For assembly, the hammer foot is inserted perpendicular to the groove, so that the groove determines the position of the undercut geometry (here the hammer foot).

The disadvantage of such embodiments is the fact that the assembly is prone to errors. Since the groove cannot be seen during assembly shortly before inserting the glider, the person installing it cannot precisely check whether the glider is correctly seated in the groove. This can lead to malfunctions in the vehicle roof if the glider does not clamp properly or is seated incorrectly or even falls out of the groove. Another disadvantage is the play of the slider in the groove, which is necessary in this known concept to insert the slider into the groove. In conjunction with the wind deflector, this creates slightly different movements of the wind deflector when opening or closing the roof opening.

It is the object of the present invention to improve known vehicle roof systems and, in particular, to simplify the assembly of the glider on the cover and to ensure long-term stability.

This task is solved by a roof system according to the characterizing part of claim 1.

According to the invention, the groove has an opening in a transverse or longitudinal direction of the vehicle, which exposes a cross section of the groove.

The opening allows the slider to be inserted into the groove in the transverse or longitudinal direction of the vehicle (depending on the longitudinal extent of the groove) and must be inserted into the groove perpendicular to the groove. The problems described above no longer occur.

Preferred embodiments of the present invention emerge from the subclaims.

In a first preferred embodiment of the invention, the opening is designed in such a way that the hammer base can be inserted laterally (or “horizontally”) through the opening into the groove in the transverse or longitudinal direction of the vehicle for mounting the slider on the cover.

Particularly preferred is an embodiment of the invention in which the groove has an undercut on both sides of the hammer foot, which is formed by a projection which extends transversely to the longitudinal extent of the groove. These engage in a neck section of the hammer base and the undercuts therefore fix the hammer base and with it the slider perpendicular to the plane that the cover spans and thus perpendicular to the groove. The slider cannot be moved vertically out of the groove.

In a further preferred embodiment of the invention, the groove has a receptacle for receiving and fixing the hammer foot in the transverse or longitudinal direction of the vehicle (along the longitudinal extent of the groove).

This receptacle preferably has a longitudinal extent in an insertion direction of the hammer foot, which essentially corresponds to the longitudinal extent of the hammer foot.

The receptacle is further preferably limited in the insertion direction by a stop in the groove against which the hammer foot is pushed during assembly. This stop advantageously prevents the hammer foot from being moved further in the assembly direction after assembly. This also simplifies the assembly itself, as the glider only has to be pushed as far as it will go in order to achieve the specified end position.

Particularly preferred is an embodiment of the invention in which the receptacle has a locking mechanism, which, as soon as the hammer foot is pushed along the groove against the stop when inserted, locks with the hammer foot, and the hammer foot and with it the slider in the receptacle against the Determines the direction of insertion. The locking mechanism advantageously prevents the hammer foot from being moved counter to the mounting direction after assembly.

The locking mechanism can be formed by narrowing the groove transversely to the insertion direction, for example in a horizontal or vertical direction tical direction. In such a configuration, the constriction is formed in the direction of an axis that lies parallel to a plane that is spanned by the surface of the lid, i.e. in the horizontal direction. Alternatively, the constriction can be formed in the direction of an axis that is perpendicular to the plane that is spanned by the surface of the lid, i.e. vertically. In both cases, the hammer foot must pass through the narrow area when it is pushed into the groove until it reaches its final position and is fixed in this position. The hammer foot and/or the groove with its constriction are designed to be so elastic that the constriction is reversibly elastically expanded to allow the hammer foot to pass through and returns to its original shape after reaching the final position.

Further alternatively or additionally, the locking mechanism can be designed in that the hammer foot has a projection or a recess, which engages with a recess or a projection in the groove when the hammer foot rests against the stop.

In a further preferred embodiment of the invention, the locking mechanism has an elevation and/or a depression in a bottom of the groove with which the hammer foot locks.

Basically, the groove for locking with the hammer base will be elastically reversibly deformed during its assembly.

The groove is preferably formed by foaming around the edge of the lid.

The invention is explained in more detail below by way of example using the attached figures.

1 shows a lid 10 with a transparent pane 16 and an edge foam 12 according to the prior art. The edge foam 12 forms a groove 14 in which a slider, not shown here, can be attached. The cover 10 is used to selectively open and close a roof opening in a vehicle roof.

In the 2 is the lid 10 the 1 shown in a view from below of a corner area of the lid 10. Here the groove 14 can be seen in a top view. The cut of the 1 runs across the groove 14 of the 2 .

A slider is inserted into the groove 14, the slider serving to control an extension of the wind deflector outwards with the aid of a preload by a spring when the cover 10 is moved backwards in the direction of the vehicle to release the roof opening in sliding contact with a wind deflector .

In the following 3 until 5 Three different concepts of a vehicle roof system according to the present invention are presented.

What is common to all of the exemplary embodiments shown is that a slider 18 has a hammer foot 20, by means of which the slider 18 is fixed in a groove 14 on a cover 10, the groove 14 having an opening 15 in a longitudinal direction of the vehicle. The opening 15 serves to be able to insert the slider 18 into the groove 14 in the longitudinal direction of the vehicle. In the embodiments shown 3 until 5 The groove 14 runs along the cover 10 in this longitudinal direction of the vehicle and accordingly the slider 18 is inserted with its hammer foot 20 along the longitudinal extent of the groove 14 via the opening 15 into the groove 14.

Of course, alternatively, the groove 14 can also be formed transversely to the longitudinal direction of the vehicle and the opening 15 will then accordingly open the groove 14 in this transverse direction of the vehicle, so that in this case the slider 18 can be inserted into the transverse groove 14 in the transverse direction of the vehicle via the opening 15.

The terms “transverse direction of the vehicle”, “longitudinal direction of the vehicle” and “vertical” are used to explain these directions when the cover is installed. Of course, the slider 18 can be installed on the cover 10 before the cover 10 is installed on the vehicle.

In all embodiments of the 3 until 5 The groove 14 ends with a stop 19 and a receptacle 30 is limited in the insertion direction of the hammer foot 20, against which the hammer foot 20 is pushed during assembly.

The hammer base is thus fixed in a horizontal direction (again with the cover installed) via this stop 19.

A vertical fixation of the hammer foot in the groove 14 is carried out in a similar manner in all embodiments 3 until 5 achieved in that the respective groove 14 forms projections 24 (see 3d ), which engage in a neck section 22 of the hammer foot 20. This ensures that the hammer foot 20 and with it the slider 18 are also fixed in a vertical direction and cannot leave the groove 14 in this direction.

Both 3 until 5 It should also be noted that the respective cover 10 corresponds to the view 2 are shown, i.e. reversed compared to the later installation state.

In the 3a , 4a and 5 Different sliders 18 and also different grooves 14 with receptacles 30 are shown, which represent alternative embodiments of the present invention.

In the 3a is a slider 18 shown in perspective with a hammer foot 20, which is connected to a slider body 23 via a narrower neck section 22. The slider 18 is intended to be pushed along the longitudinal extent of the groove 14 through an opening 15 into a receptacle 30 of the groove in order to securely store the slider 18 in a foamed edge 12 of the cover 10. As already explained, the assembly takes place along the longitudinal direction of the vehicle (x-direction) and the groove 14 also extends in the x-direction. The groove 14 ends in the longitudinal direction of the vehicle at the rear with a stop 19 against which the hammer foot 20 is pushed during assembly. The receptacle 30 has a longitudinal extent which essentially corresponds to the longitudinal extent of the hammer foot 20. So that the hammer foot 20 is fixed against later displacement not only in the assembly direction by the stop 19, but also against the assembly direction, a narrowing 36 is provided, which limits the expansion of the groove 14 in the transverse direction. This constriction 36 serves to fix the hammer foot 20 against the mounting direction within the receptacle 30 so that it cannot detach from the stop 19.

In front of the constriction 36, a funnel-shaped insertion aid 42 is provided, which serves to center the hammer foot 20 towards the center of the opening 15 during assembly. The slider body 23 is wedge-shaped at the end with which it is pushed against the insertion aid 23 for assembly in order to make it easier to overcome the narrowing 36.

The 3d shows a cross section through the edge foaming 12 of the lid 10 through the groove 14 in the area of the receptacle 30. The groove 14 is delimited on the one hand by the base 26, and here forms a channel-like space for receiving the hammer foot 20. The groove 14 has in the area of the neck section 22 projections 24 which extend towards each other from both sides of the groove and thus only leave a slot in the groove open, in which a neck section 22 of the slider 18 is displaced along the longitudinal extent of the groove 14 (during assembly) or in the area of the receptacle 30 is stored. Accordingly, the slot 46 of the groove 14 in the area of the receptacle 30 has a width that corresponds to the neck dimension 44.

In the area of the constriction 36 the width of this slot is reduced. The fixing of the slider 18 in the vertical (z direction) according to the section of the 3d is in this form in all embodiments 3 until 5 realized in a similar way.

The formation of a locking mechanism according to the 3a until 3d corresponds to a first embodiment of the invention, the locking here taking place by a rear hook of the hammer foot 20 behind and with the narrowing 36 of the groove 14, which counteracts a movement of the slider 14 against the assembly direction and away from the stop 19.

In the 4a and the 4b An alternative embodiment is explained, in which there is no narrowing of the groove 14 transversely to its longitudinal extent. A locking mechanism is implemented here, in which the bottom 26 of the groove 14 is guided over different levels. In the cross section of the 4a as well as in the longitudinal section 4b a depression 40 of the bottom 26 of the groove 14 is shown in the area of the receptacle 30. The bottom 26 of the groove 14 is offset downwards here, so that the hammer foot 2, as soon as it reaches the stop 19, is lowered relative to the bottom 26 in the area in front of the receptacle 30.

A vertical edge 44 is therefore formed between the bottom 26 and the recess 40, which forms a further stop for the hammer foot 20, which prevents the hammer foot 20 from being displaced even against the assembly direction in the assembled state. The hammer foot 20 is thus secured next to the stop 19 by this vertical edge 44 as a further stop. Before the bottom 26 sinks into the recess 40, there is still an upwardly extending nose 32 of the bottom 26 seen, which further increases the area of the vertical edge 44 against which the hammer foot 20 rests. This further increases the effect of this locking mechanism or this hooking mechanism. This nose 32 must also be overcome during assembly by a reversible elastic deformation.

While the embodiments of the 3a until 3d and 4a and 4b represent two locking mechanisms in which the cross section of the groove is once in the horizontal direction ( 3a until 3d ) and once in the vertical direction ( 4a and 4b) is limited is in the 5 Another alternative locking mechanism is shown. As already explained, here too a slider 18 is inserted into an opening 15 of a groove 14 for assembly and pushed against a stop 19, which in this end position fixes the slider 18 in the insertion direction. In the opposite direction, i.e. opposite to the insertion direction, a concept is provided here in which a projection or pin 28 is arranged on the hammer foot 20, which locks in the end position of the mounted slider 18 with a corresponding recess 38 in the groove 14 and thus the locking mechanism trains. The projection 28 of the hammer foot 20 is provided on its underside, that is, running counter to the bottom 26 of the groove 14. Accordingly, the recess 38 is provided in the bottom 26 of the groove 14. Of course, such projections and recesses can also be arranged laterally on the hammer foot 20 and at a corresponding position in the groove 14. Alternatively, the groove 14 can have a projection and the hammer foot 20 can have the corresponding recess.

Of course, a slider 18 according to the invention does not have to have just one, for example elongated, hammer foot 20, but this can also be replaced (in all embodiments) by several smaller hammer feet, which then together take on the function of an elongated, continuous hammer foot.

In all embodiments, it is essential that the edge foam 12 is made of an elastic material, such as PU foam. Since the hammer foot 20 of the embodiment 3 from to 3d and 4a and 4b, is determined by the fact that it first overcomes an obstacle and hooks behind it in the end position, the edge foam and with it the groove must be able to be reversibly elastically deformed if the hammer foot 20, for example, due to the narrowing 36 of 3b is pushed or the nose 32 of 4a and 4b overcomes. On the one hand, the projections 24 of the groove 14 according to the 3d for mounting the slider 18 reversibly bent upwards and the nose 32 of 4a be pressed downwards in a reversible and elastic manner. When inserting the hammer foot 20 through the constriction 36, it will be opened reversibly in a transverse direction in order to be able to insert the slider 18.

While in the embodiment according to the 3a the insertion aid 42 is designed by the funnel-shaped design of the constriction 36, an insertion aid of the embodiment according to the 4a and 4b achieved by an insertion bevel 34, with which the hammer foot 20 is provided on its front lower edge in the insertion direction. The insertion bevel 34 makes it easier to insert the slider 18 into the groove 14 over the nose 32.
