Description

The invention relates to a vehicle roof with a roof opening and a cover which is arranged in the roof opening by means of a bearing device and can be moved from a closed position at least into a ventilation position, the bearing device having a pivot bearing which supports the cover on a bearing part supported on the vehicle roof, wherein the pivot bearing has a bearing axis on which a bearing bush is arranged, which pivots the bearing part and which extends through a recess, in particular an elongated hole, in a cover holder attached to the underside of the cover, the bearing axis in the recess is accommodated so as to be adjustable relative to the cover and can be fixed in a position set relative to the cover on the cover holder by means of a clamping device which can be tensioned via a screw connection section of the bearing axis.

From the EP 2 433 829 B1 a generic vehicle roof has become known in which a pivot bearing of a bearing device of the cover has a bearing axis in the form of a screw with a thread, a thread-free shaft and a screw head. A bearing bush, which supports a bearing arm of the bearing device, is placed on the thread-free shaft of the screw and is supported towards the screw head via a washer. A cover holder of the cover has an elongated hole in which a nut is inserted in a rotationally fixed but longitudinally displaceable manner. The thread of the screw is screwed into the nut from the side of the bearing arm so that it clamps the bearing bush against one side of the cover holder via the screw head and the washer and the clamping force on the other side of the cover holder is supported by the nut. The screw head protruding axially beyond the bearing bushing causes a greater axial length of the pivot bearing, which requires a corresponding installation space in the z-direction on or under the cover.

The invention is based on the object of creating a vehicle roof of the type mentioned at the beginning, which is improved with regard to the design of the pivot bearing.

In the vehicle roof mentioned at the beginning, this object is achieved according to the invention in that the clamping device has an axial support part and an axial clamping part, which can be clamped against one another on the cover holder, with either the bearing axis having a screw head as an axial support part and the bearing bushing as an axial clamping part on the screw connection section of the bearing axis is screwed on or the bearing bush is formed as a unit with the bearing axis and forms the axial support part and a nut is screwed onto the bearing axis as an axial clamping part.

Advantageous refinements of the invention are given in the dependent claims.

Because, according to the first solution, the bearing axis has a screw head as an axial support part and the bearing bushing is screwed onto the screw connection section of the bearing axis as an axial clamping part, the bearing bushing takes on the function of a nut that can be screwed onto the bearing axis. An additional clamping or clamping part for the axial fixing is not required. The pivot bearing with the bearing axis and the bearing bush can therefore be formed with a comparatively short axial length.

In the second solution, in which the bearing bush is formed as a unit with the bearing axis and forms the axial support part and a nut is screwed onto the bearing axis as an axial clamping part, a simplified structure of the pivot bearing with a short axial length is also provided. Another advantage is that such a screw connection in the axis of rotation enables torque-free mounting in the cover holder in the case of load through the cover in the z-direction, since only the torque in the rotatably mounted bearing bush acts on the screw head.

The bearing bush is thus directly axially fixed via its screw connection. A sleeve-shaped bearing on a bearing axis known from the prior art, on the other hand, requires an additional axial fixing or fastening of the bearing bush.

The cover holder is expediently integrated on the underside of the cover and attached to it in a non-detachable or at least non-destructively detachable manner.

The bearing bushing expediently contains a first collar which rests against the cover holder and transmits the axial clamping force.

If the bearing bush has an additional second collar which is axially spaced from the first collar, the bearing part can be mounted between the two collars. Axial guidance of the bearing part is largely free of play, but allows the bearing part to pivot with respect to the bearing bush.

According to a preferred embodiment it is provided that the one or first collar is arranged as an independent component, in particular as a washer or the like, on or on the bearing bush and that the other collar is integral or is formed in one piece with the bearing bush. On the other hand, it can also be provided that the two collars are formed in one piece or integrally with the bearing axis.

The bearing bushing expediently contains a locking guide which engages in the recess of the cover holder, which is formed in particular as an elongated hole, and which holds the bearing bushing in it in a rotationally fixed manner. The locking guide can, for. B. be formed as a rectangular raised projection on the bearing bush or in the form of two guide webs or the like.

According to a preferred embodiment it is provided that the cover holder has a lower section which is formed with a crank at the lower end of the elongated hole, so that the locking guide can be introduced tangentially into the elongated hole. This makes assembly easier, since an axial feed movement of the bearing bush relative to the cover holder is not required. The lower section of the cover holder is cranked out of the plane of the cover holder by at least the thickness or axial height of the locking guide.

The bearing part is expediently a pivotable bearing arm which is attached or mounted on the vehicle roof, in particular on a slider or slide mounted on a roof-side guide.

The longitudinal guides and the bearing units of the cover are provided on both sides of the vehicle roof and symmetrically to the roof opening or to the vehicle longitudinal axis. The description is essentially based only on these guide and bearing units on one of the two long sides of the cover.

A lid for closing and at least partially releasing the roof opening is any roof element that can assume this function regardless of its shape or design. Such a roof element is, for example, a transparent glass cover or plastic cover, to which a cover holder is attached and fastened in particular by foaming.

The roof structure is largely symmetrical to a longitudinal center line of the vehicle roof 1 so that the following description based on the one long side of the roof opening 3 arranged storage device with the storage units 6th and 8th he follows.

The front longitudinal guide 7th for the front storage unit 6th and the rear longitudinal guide 9 for the rear storage unit 8th can be arranged or formed on or by the same guide rail or they are arranged or formed on different guide rails.

The front storage unit 6th has a bearing part 10 on (see 2 until 4th ), the Z. B. as a bearing arm 11 is formed and one on the longitudinal guide 7th displaceably mounted slider or slide is arranged and guided with this on a trajectory curve or is pivotably mounted thereon. The bearing part 10 is about a pivot bearing 12th with a lid holder 13th pivotally connected to the underside of the lid 14th with a mounting leg 15th is firmly attached and in particular in a foam edge or foaming 16 of the lid 2 is firmly embedded. The one from the lid 2 vertically downwardly extending lid holder 13th contains a recess 17th , preferably as an elongated hole 18th is formed, which is expediently essentially in the vertical or z-direction or essentially perpendicular to the surface of the cover 2 extends.

The swivel bearing 12th has a bearing axis 19th on, preferably by a screw 20th is formed. The screw 20th lies with her screw head 21 on the side of the lid holder pointing outwards in the transverse direction 13th extends through the elongated hole 18th and over the opposite side of the lid holder 12th out. The bearing part 10 has a bearing ring 22nd on, which is on a bearing bush 23 is stored. The bearing bush 23 contains an internal thread at its central cylindrical opening, with which it is threaded on one of the elongated hole 18th protruding screw connection section 24 the screw 20th is screwed on. The bearing bush 23 has a first covenant 25th and a second fret 26th on, which are spaced from each other so that the bearing ring between them 22nd axially guided, but relative to the bearing bush 23 is held pivotable. The first covenant 25th is preferably integral at the inner or rear end 27 the bearing bush 23 formed, whereas a washer 28 the second fret 26th forms. The washer 28 is on a paragraph 29 at the outer or front end 30th the bearing bush 23 centered and is placed on the bearing bush 23 put on and in particular firmly pressed on after the bearing bush 23 in the bearing ring 22nd has been used.

When screwing the bearing bush 23 on the screw 20th towards the lid holder 13th is about the second fret 26th or via the washer inserted in between 28 an axial clamping or clamping force between the bearing bush 23 and the screw head 21 upset. The bearing axis is by means of the clamping device formed in this way 19th or the screw 20th on the lid holder 13th Can be fixed or clamped after the correct position of the bearing axis 19th or the screw 20th in the elongated hole 18th relative to the lid 2 has been set.

This allows the lid 2 via the pivot bearing 12th in its correct position in the roof opening 3 relative to the bearing part 10 brought and set in this position. The definition is made on the cover 2 permanently attached lid holder 13th without the interposition of another component such as B. an otherwise additionally attached cover support.

On the one hand the screw head 20th on the lid holder 13th and the opposite screw connection with the bearing bush 23 itself takes place, is the axial length of this pivot bearing 12th comparatively small with the adjusting device and the clamping device and requires only a small amount of installation space in the transverse direction or in the y-direction.

With an in 5 The modified embodiment shown is the second collar 26th the bearing bush 23 , the one on the cover carrier 13th at the outer or front end 30th the bearing bush 23 firmly or in one piece formed on this or integrally formed thereon. When assembling the bearing ring 22nd of the bearing part 10 on the one at its inner or rear end 27 initially cylindrically shaped bearing bush 23 put on. Then the bearing bush 23 , which is formed from a deformable bearing material such as brass or the like, by Kaltumformumg such. B. reshaped by tumbling, the first fret 25th is formed.
