Description

The The invention relates to a vehicle roof with a rear edge exhibitable and above the roof sliding roof part according to the preamble of claim 1

From the EP 0 863 817 B1 Such a vehicle roof is known. In this, an openable roof part is raised by means of a rear opening mechanism and transferred at the beginning of the sliding movement to a separate support lever which is slidably mounted in an upwardly open, laterally offset extension of the guide rail with its lower end. During the transfer of the release mechanism to the support lever both elements are engaged for a short movement phase, whereby a static overdetermination arises. Under certain circumstances, the drive may require increased drive forces in this phase, which also negatively influence a sensor system for anti-trap protection.

Out the US 2002/0125743 A1 discloses a vehicle roof is known in which a Outside led openable roof part is guided with a very simple, rigid holder having mechanics. The increase takes place over inclined ramps in the guide rails, so that the exhibition of the trailing edge only at the same time with one Displacement of the roof part can be done.

Of the Invention is based on the object of developing a vehicle roof such that the openable roof part at the exhibition and during the shift continuously through supported the release lever becomes.

These The object is achieved by the Features of the claims 1 and 12 solved. advantageous Embodiments of the invention are specified in the subclaims.

The The invention basically provides that the trailing edge of the displaceable Roof part in all movement positions continuously through the same Lifting lever supported will, so no transfer to separate support lever must be done. The release levers are actuated by control slides, the starting from the closed position over the fan position to the full opening position be moved in the same direction. The control sleds are also pressing a locking device, which is a displacement of the roof part during the Blocking movement blocked.

According to one advantageous embodiment the locking device of a pivotally mounted on the release lever articulated locking lever formed. At this a locking bolt is arranged, which is in engagement with a roof-proof backdrop. On the locking lever Furthermore, a control pin is arranged, which with a control link of the control carriage is engaged.

Especially an embodiment is advantageous at the same time the release lever with a front sliding element and with a rear slider in engagement with the control link of the control carriage stands.

According to one further advantageous embodiment is the sliding roof element near its front edge at one hinged at least pivotable front slide, this being front slide connected to the control slide via a control lever stands. The control lever is preferably on the front carriage via a Articulated swivel joint. The control lever preferably has one Setting on, in which the control slide engages with a control pin. This backdrop preferably has a straight section, the one Shifting the control slide relative to the still stationary one allows front slide when exhibiting in the fan position. The gate also preferably has a bent portion, by which a locking pin arranged on the control lever by means of Control pin unlocked when moving the roof part backwards becomes and thereby in the course of the opening movement a synchronous Movement of the front carriage with the control slide allows.

Of the Release lever is preferably in two parts with an outer leg and an inner leg. Embrace the two thighs the control slide partly on both sides. On one of the thighs the locking device is attached while at least at the other Leg sliders for the engagement are arranged in the control link.

The front sliding element preferably has a backdrop with at least a rising portion in which a sliding element of a slidably mounted front connection of the sliding roof part is. As a result, the sliding roof part is additionally liftable front and can thereby on the one hand by a seal in the front area the roof opening On the other hand, the roof part can thereby Move to the rear take a flatter inclination, the Wind less opposition.

The invention is particularly suitable for an exterior sunroof (ASD). This can also be advantageous part of a so-called fixed-element convertible, in which a sunroof function initially allows a partial opening of the roof before the entire roof moves into a storage space and thereby releases the entire interior upwards.

following the vehicle roof is by way of example with reference to an embodiment closer to the drawing explained. It shows:

This in 1 shown vehicle roof 1 has from front to back one behind the other lying on a cowl above the windscreen subsequent, with its trailing edge exhibitable Windabweiserlamelle 2 , a movable roof part 3 and a rear fixed roof part 4 on. The preferably formed in the form of a lid made of glass movable roof part 3 is issued by means of a mechanism described in detail below with its trailing edge in a fan position and starting from this on the fixed roof part 4 veschiebbar to the rear, with a roof opening 5 is largely uncovered and wherein the movable lid 3 in contrast to conventional, also referred to as spoiler roofs lift-sunroofs always at its rearward displacement near its trailing edge 32 is supported. Such from the aforementioned EP 0 863 817 B1 known openable vehicle roofs are referred to as exterior sunroofs (ASD), as one the trailing edge 32 of the lid 3 supporting part of the mechanism - here a release lever 40 - in one to the top of the vehicle roof 1 open leadership 46 even with a shift behind the roof opening 5 slidably supported. The leadership 46 gets up through a seal 49 covered, the the release lever 40 evades backward in the process.

The wind deflector lamella 2 is only optional available; It is therefore also in the 3 to 12 omitted. Instead, is in 12 a conventional wind deflector 73 shown with the roof closed at the front edge of the roof opening 5 below the movable roof part 3 lies and only when pushed back to the roof part 3 preferably spring-loaded pivots in its operative position upwards.

The roof opening 5 is bounded laterally by lateral roof pillars 6 , These can be part of the fixed vehicle roof 1 However, you can also with a fixed-element convertible on the rear roof part 4 be movably arranged and according to the method of the movable roof part 3 over the roof part 4 from the front of the fixed vehicle roof 1 solved and, for example, after pivoting to the roof part 4 be sunk into a storage space with the entire roof package.

At the side roof pillars 6 is each a guide rail 7 arranged, extending both sideways the roof opening 5 as well as behind the roof opening 5 in the roof part 4 extends into where she takes the lead 46 for the lower support of the release lever 40 during the displacement of the roof part 3 over the roof part 4 forms. In the guide rails 7 is each a cable channel 8th in which a train- and pressure-resistant drive cable 9 is guided, which is connected to an electric drive, not shown. In the 3 to 12 is only one guide rail 7 shown on a page with the associated mechanics. All parts, however, are mirror images of a central longitudinal axis on both sides of the roof opening 5 available.

The movable roof part 3 is near its leading edge 31 via a front connection 33 with a sliding element 35 swiveling and sliding on a front slide 10 stored. The front sled 10 is with a pair of front sliding elements 11 and a pair of rear sliding members 12 in opposite guideways of the guide rail 7 slidably guided. At the front sled 10 is a backdrop 13 provided a first horizontal section 14 , followed by a second rising section behind it 15 and then a horizontal third section 16 having. In this scenery 13 grips the sliding element 35 the front connection 33 of the roof part 3 displaceable.

Near the far end 32 of the movable roof part 3 is the release lever 40 with a joint 43 at one with the roof part 3 connected rear connection 34 hinged pivotally. How best in 12 to recognize, is the release lever 40 formed in two parts in its front region: an outer leg 42 and an inner thigh connected thereto 41 grip from below a control slide 50 in the region of an upwardly arched arcuate control link 54 , The control gate 54 is on the outside of the control slide 50 provided in the rear area. In the control link engages the release lever 40 with a front sliding element 44 and one in the middle of the release lever 40 on the underside arranged rear sliding element 45 one. One in shape to the control gate 54 identical control link is preferably also on the inside of the control slide 50 formed in the rear region at the same height in the X direction and in the Z direction seen. The usual coordinate system in vehicle construction is in 12 indicated. The X-direction is set parallel to the vehicle's longitudinal axis, the Y-direction parallel to the vehicle's transverse axis, and the Z-direction parallel to the vehicle's vertical axis. In this inwardly open control link engage in mirror image to the front sliding element 44 and to the rear slider 45 arranged sliding elements on the inner leg 41 of the release lever 40 one. The engagement of two sliding elements 44 and 45 in the taxation 54 at the control slide 50 ensures a symmetrical force transmission and a particularly stable support of the lid 3 , The function is also by a release lever 40 guaranteed, with only two sliding elements 44 and 45 on one side in a control frame 54 intervenes.

The tax sled 50 is with a pair of front shoes 51 and a pair of rear shoe 52 in a guideway of the guide rail 7 slidably mounted. At the height of the rear shoe 52 is at the same time on the outside a connection 53 to the drive cable 9 intended. The drive motor, not shown, thus actuates the movable roof part 3 exclusively via a shift of the control slide 50 , At the control slide 50 is in the front area to the inside open another backdrop 55 arranged. Furthermore, in the front area of the control slide 50 an outward facing control pin 56 intended. The scenery 55 serves to actuate a locking device 60 coming from a parallel to the inner thigh 41 of the release lever 40 and the control slide 50 arranged locking lever 61 is formed, which at its rear end with a joint 62 on the inner thigh 41 of the release lever 40 is pivotally mounted and at its front end on the inside, ie the roof opening 5 facing, a locking bolt Ver 63 and on the outside a control pin 64 carries, with the control pin 64 opposite the locking bolt 63 slightly offset down and back.

The locking bolt 63 engages in one on the inside of the guide rail 7 provided backdrop 72 a, which has an initially sloping course from front to back, which then into a horizontal track of the guide rail 7 passes.

The tax pin 64 engages in the scenery 55 at the control slide 50 one.

The tax pin 56 of the control slide 50 is engaged with a backdrop 22 at a control lever 20 , The control lever 20 is at its front end with a joint 21 at the front sled 10 hinged. The scenery 22 points from the front to the back first a straight section 23 on, which is near the rear end in an arcuate upwardly bent portion 24 passes. At the rear end of the control lever 20 is also outwardly projecting a locking pin 25 arranged in a backdrop 70 on the guide rail 7 engages, which is formed at the front end as a short vertical backdrop and down arcuately in a horizontal guideway 71 the guide rail 7 passes.

Hereinafter, the function of the above-described mechanism from the closing position (see FIG 1 . 3 and 6 ).

In the closed position becomes the openable roof part 3 flush with the fixed vehicle roof 1 and the rear roof part 4 in the roof opening 5 held. This will be the front end of the lid 3 over the front connection 33 and the slider 35 in the horizontal section 14 the scenery 13 of the front sled 10 held. The front sled 10 in turn, is about its sliding elements 11 and 12 held in the Y direction and in the Z direction and over the control lever 20 , its latch pin 25 in the vertical backdrop 70 is secured in the X direction.

The back end of the lid 3 gets over the release lever 40 , whose sliding elements 44 and 45 in engagement with the control link 54 of the control slide 50 held, held in the Y direction and in the Z direction and by the engagement of the locking bolt 63 in the scenery 72 secured in X direction.

The opening movement of the lid 3 begins with an expelling movement of the trailing edge 32 , For this purpose, the drive motor, not shown, moves the drive cable 9 to the rear. About the cable connection 53 is the tax sled 50 by the same amount X, (see 3 ) moved backwards. The control gate moves 54 relative to the sliding elements 44 and 45 of the release lever 40 from the in 4 or 9 position shown in the in 10 shown position. While the front slider 44 in the closed position ( 9 ) in the upper area and the rear sliding element 45 at the rear lower transition of the arcuate control link 54 is located, has the front sliding element 44 in the raised position of the trailing edge 32 of the lid 3 in the lower front transition area and the rear slider 45 in the upper middle area of the control gate 54 emotional. This will give the joystick 40 imposed a pivoting movement in the counterclockwise direction, to the in 10 shown Ausstellposition the lid 3 leads. When moving the control slide 50 for the production of the Ausstellposition has the control pin 56 in the straight section 23 the scenery 22 at the control lever 20 traveled a corresponding free travel, ie the control lever 20 Holds the front sled 10 about the engagement of the locking pin 25 in the vertical part of the backdrop 70 unchanged in its position. At the same time is through the engagement of the control pin 64 in the scenery 55 the locking bolt 63 in the sloping part of the scenery 72 something back and down, but without already in the horizontal track of the guide rail 7 to have occurred. This secures the locking bolt 63 the release lever 40 in the Ausstellposition still against a shift to the rear. How out 7 To see, has been in the Austellbewegung the trailing edge 32 of the lid 3 also the sliding element 35 at the front connection 33 of the lid 3 by a small amount X ₂ in the horizontal section 14 the scenery 13 moved backwards. This will get the leading edge 31 of the lid 3 from the front edge of the roof opening 5 free, thereby squeezing a seal arranged there with appropriate noise and wear is prevented.

For complete opening of the lid 3 becomes the tax sled 50 through the drive cable 9 moved further out of the open position. This is the locking bolt 63 through the leadership of the tax pin 64 in the scenery 55 in the horizontal section of the backdrop 72 transferred (see transition from 7 on 8th ). At the same time the sliding element moves 35 at the front connection 33 the lid over the second inclined portion 15 up into the horizontal third section 16 the scenery 13 so that also the leading edge 31 of the lid 3 is raised. The front sled 10 is doing first over the control lever 20 kept unchanged in its position ( 8th ), as is the control pin 56 of the control slide 50 still in the horizontal part 23 the scenery 22 located. If this control pin 56 on the curved section 24 the scenery 22 concerns, he presses the rear end of the control lever 20 down, leaving the latch pin 25 from the vertical part of the backdrop 70 down into the guideway 71 can occur. This is also the locking of the front slide 10 and this is canceled by attachment of the tax pin 56 at the far end of the scenery 22 from the control slide 50 and the control lever coupled thereto 20 pulled back.

In the final position ( 5 ) is the roof opening 5 largely uncovered. The connection 33 near the front edge 31 of the lid 3 is directly in front of the rear roof section 4 , The closing movement of the lid 3 is exactly in reverse order to the sequence described above.

An advantage of the above-described mechanism for an externally guided sunroof is that the drive from the closed position on the Ausstellposition the trailing edge to the full open position on a single control slide 50 in the same direction. All necessary temporary interlocks of the front slide 10 and the release lever 40 against an early shift are directly or indirectly from this tax sled 50 controlled. The mechanics build compared to the beginning acknowledged state of the art significantly smaller. In the X-direction is on each side a single continuous guide rail 7 used in the rear guide 46 for the support of the release lever 40 passes. As a result, the width of the mechanism in the Y direction is also significantly reduced. Also with respect to the height (Z direction) is the Me described above chanik reduced to a minimum. The flat arched backdrop 54 requires minimal drive forces to produce the Austellbewegung for the deployment lever 40 , It is a continuous smooth operation of the roof part 3 ensures that also allows a passage from the closed position to the full open position, without requiring high and erratic driving forces that could deceive a pinch protection sensor.
