Description

Roof system

Technical Field

The invention relates to a roof system with a roof region which is fixed to a vehicle in a mounted state ready for operation and has a roof opening which is open to a vehicle interior and can be closed by a roof cover which is fitted into the roof opening from below with reference to a vehicle height direction in a closed position and which has a circumferential, upwardly open channel on the edge side, into which a downwardly directed circumferential web of the edge of the roof opening protrudes in the closed position of the roof cover.

Background

Such a roof system is known from DE10319783B 4. The known roof systems have a stationary roof region, which is provided with a roof cutout. A glass roof panel is fitted into the roof cutout. The roof of the glass vehicle has an upwardly open groove at its edge region. In the mounted state of the glass roof in the roof cutout, the webs of the edge region of the roof cutout protrude into this groove. The glass roof is mounted in the roof cutout from below, so that the groove of the glass roof acts from behind in the vehicle height direction on the web of the edge region of the roof cutout. In order to achieve a sealed, durable connection between the glass roof and the edge region of the roof cutout, a sealing device is positioned in the region of the groove. The glass roof is bonded to the edge region of the roof cutout by means of an adhesive tape.

Disclosure of Invention

The object of the present invention is to create a roof system of the type mentioned at the outset which enables an opening function for a roof cover with simple means.

The object is achieved in that the roof is provided with a control movement mechanism by means of which the roof can be moved between a closed position and an open position in which the roof is at least partially open to the roof opening, in which the roof is moved downward in the vehicle height direction and at least partially backward in the vehicle longitudinal direction below a roof region fixed to the vehicle. The solution according to the invention on the one hand enables a particularly safe support of the roof top upwards in its closed position. This prevents the roof cover from falling out of the roof opening upwards, in particular in the event of a crash of the vehicle. Roof systems can thus achieve particularly good results in the extrusion tests which are common for checking roofs. On the other hand, according to the invention, the roof is movable into the open position despite the roof being safely supported in its closed position, whereby additional fresh air can be supplied to the vehicle interior. The control movement is configured in a simple manner such that the roof is moved from its closed position only downward and rearward in order to at least partially open the roof opening. The solution according to the invention is particularly advantageously suitable for private cars. The invention can also be used for other types of vehicles, in particular in the form of different wheeled vehicles or rail vehicles.

In one embodiment of the invention, the control movement mechanism has two guides which are fixed to the vehicle for moving the roof, which extend in the longitudinal direction of the vehicle and are arranged at a distance from the roof opening, viewed in the transverse direction of the vehicle, on opposite sides. The guide device is thus positioned laterally outside the roof opening fixedly with the vehicle. The size of the roof opening is thereby not hindered by corresponding guides positioned in the region of the roof opening.

In a further embodiment of the invention, a drive system is associated with the control movement mechanism, by means of which drive system the roof can be moved between the closed position and the open position. The drive system is preferably designed such that the control movement is driven synchronously in the region of the opposing guide. The drive system is advantageously provided with an electrical drive unit, which is formed by at least one electrical drive motor and an associated transmission. The drive system furthermore has a longitudinally extending tie rod and/or pressure rod for transmitting the drive force from the electrical drive unit to the control movement mechanism. The respective tie rod and/or pressure rod may be formed by a flexible spiral cable, a bowden cable, a rope transmission system or a flexible toothed rod.

In a further embodiment of the invention, the roof covers each have a laterally extending structure on opposite sides, which is positioned below the roof opening in the closed position and extends beyond the edges of the roof opening in the direction of the vehicle transverse direction toward the respective guide device. The expression "extends beyond the edge of the roof opening" means here that the laterally extending structure extends in the closed position laterally outwardly along the edge region of the roof opening underneath this edge region. An L-shaped angle profile or a plurality of transverse webs arranged parallel to one another or a transverse frame or the like can be provided as the transverse extension. The laterally extending structure is shape stable and preferably is composed of metal.

In a further embodiment of the invention, a beam profile extending along the respective guide device is fastened to the respective transverse extension, which beam profile is connected to a further functional component of the control movement mechanism. The two beam profiles on opposite sides of the roof are thus firmly and kinematically connected to the roof by means of the respective laterally extending structures.

In a further embodiment of the invention, the beam profile has, as a functional component, a guide slide at the front hinge point, which guide slide is guided in a linearly movable manner in a guide rail of the guide device. The guide means are preferably formed on each side of the roof opening by a rail profile, which is preferably embodied as an extruded profile with at least one upwardly open guide channel. The guide slider may have at least one sliding shoe or at least one rolling element in order to achieve a linear-motion-capable guide in the guide rail of the guide device.

In a further embodiment of the invention, the guide slide is designed such that the beam profile can be moved in a further slight rotational movement about a pivot axis extending in the transverse direction of the vehicle at the front hinge point. The beam profile can thereby be pivoted about its front hinge point in a limited manner in a pivot plane extending in the height direction and in the longitudinal direction relative to the guide rail of the guide device.

In a further embodiment of the invention, the beam profile is connected at a rear hinge point to a further functional component in the form of a lifting mechanism which is provided for lowering the rear hinge point from the closed position of the roof cap or for lifting the rear hinge point into the closed position of the roof cap. By means of this lowering or lifting movement of the rear hinge point, a slight pivoting movement is forcibly produced for the beam profile in the region of the front hinge point, which pivoting movement can be absorbed by the guide slider. For this purpose, the guide slide is provided with at least one sliding shoe which is spherical or is embodied as a diamond in cross section, so that a slight tilting movement of the sliding shoe and thus of the guide slide is achieved. The lifting means is preferably realized by a mechanical positive guide.

In a further embodiment of the invention, the linear guide is coupled to the lifting mechanism, which in the lowered functional position moves the beam profile longitudinally along the guide rail. The lifting mechanism is responsible for lowering or lifting the hinge point behind the roof. In order to enable the roof to be moved back from the lowered intermediate position into an open position at least partially into the stationary roof region, a linear guide is provided.

In a further embodiment of the invention, the drive system has a drive slide in the region of each guide device, which drive slide is coupled to a functional part of the control movement mechanism in order to facilitate a synchronous parallel displacement of the opposite sides of the roof. The drive slide in each guide device preferably drives a respective linear guide which forcibly drives the beam profile via the hinge point behind the lifting mechanism and the beam profile. The hinge point arranged in front of the beam profile is thus also moved with the guide slide, so that a parallel displacement of the opposite sides of the roof is possible.

In a further embodiment of the invention, the lifting device has a rocker guide, which is fixed to the vehicle, in the region of the guide device and a control lever, which is pivotably articulated at a hinge point behind the beam profile, and can be lowered and raised by means of a rocker pivot in the rocker guide. The rocker guide and the rocker journal, which are fixed to the vehicle, define a positive control for the control rod in such a way that this control rod is forced downward from an at least largely upright position when the linear guide is moved and is pulled back together by the linear guide in the lowered, flat position along the longitudinal direction of the guide. The rocker guide preferably extends in the height direction at the height of the closed position and further back in the longitudinal direction of the guide device, so that the control lever is guided positively over its entire movement path.

In a further embodiment of the invention, the control lever is connected with a lever end remote from the rear hinge point of the beam profile to a guide slide of the linear guide mechanism, which guide slide is guided in a linearly movable manner in a guide rail of the guide device. The guide slide is preferably provided with a drive slide of a drive system in a manner capable of transmitting motion. The guide slide is advantageously coupled mechanically, preferably in a form-fitting manner, to the drive slide.

In a further embodiment of the invention, each guide device is provided with a water guide, and the roof is provided with a water outlet pipe which is associated with a channel and protrudes toward the respective guide device in order to lead water which is caught in the channel of the roof into the water guide of the guide device. The roof cap preferably has at least one water outlet connection on each longitudinal side, so that water can be guided out of the channel into two opposing guides.

In a further embodiment of the invention, the curvature of the roof region, which is fixed to the vehicle, in the region of the roof opening and the orientation of the guide means at the height of the roof opening, as seen in the longitudinal direction of the vehicle, are aligned obliquely to one another in such a way that the front edge of the roof cover strikes the front edge section of the roof opening when the roof cover is moved longitudinally from the open position forward toward the closed position. The roof and thus the beam profile thus do not have to be lifted in the region of the hinge point in front of the beam profile. More precisely, the front region of the roof cover is approximately forced into the contour of the roof opening, since the roof region fixed to the vehicle is lowered longitudinally forward relative to the plane of the guide device or the guide device is raised at the level of the roof opening.

Further advantages and features of the invention result from the following description of a preferred embodiment of the invention, which is shown by means of the drawings.

Detailed Description

The personal car according to fig. 1 has a roof region which is connected to a windscreen (shown on the left in fig. 1) in the longitudinal direction of the vehicle and which is provided with a roof system which is described in detail later with reference to fig. 1 to 13. The roof system has a roof region 1 which is fixed to the vehicle in the installed state and which extends over the entire length and width of the roof. The roof region 1, which is fixed to the vehicle, is firmly connected to the body carrier 3 of the personal car. The roof region 1 fastened to the vehicle can be connected directly to the respective roof rail and roof cross rail of the body carrier 3, in particular by means of adhesive bonding. The roof region 1 fastened to the vehicle can alternatively be firmly connected, preferably glued, to a carrier frame, which in turn can be fastened to the vehicle body carrier structure 3, where it is fastened to the respective roof-side rails and cross members. In the exemplary embodiment shown, the roof region 1 fixed to the vehicle is designed as a glass roof region. The roof region 1, which is fixed to the vehicle, has a generally rectangular roof opening D, which is delimited by a circumferential edge region with circumferential edge webs 14 pointing downward in the vehicle height direction, approximately at the level of the front seat of the vehicle interior of the personal car. In the closed position, roof opening D is sealed off hermetically by roof 2, which is likewise currently made of glass and thus forms a glass roof. On the bottom side facing the vehicle interior, a roof region 1 and a roof 2, which are fastened to the vehicle, are assigned light-shielding means, not shown in detail, in order to be able to shield the respective transparent glass surfaces of the roof 2 and of the roof region 1 fastened to the vehicle.

As can be seen from fig. 2 to 7, the horizontal plane is arched over its entire longitudinal extent, viewed in the longitudinal direction of the vehicle, compared to the roof region 1, which is fixed to the vehicle. The roof cover 2 is fitted in its closed position (see fig. 5) flush with the outside of the roof area 1 fixed to the vehicle and in a row into the roof opening D. The roof region 1, which is fixed to the vehicle, is arched upwards not only in the longitudinal direction of the vehicle, but also in the transverse direction of the vehicle.

The roof cover 2 has, at its peripheral edge, a peripheral groove 13 which is open upwards and into which a peripheral web 14 of the edge region of the roof opening D protrudes in the height direction in the closed position of the roof cover 2. The webs 14 and/or the outer wall sections of the groove 13 are designed slightly elastically and flexibly. The circumferential edge of the roof 2 also has a circumferential sealing device, not shown in detail, which additionally seals the edge of the roof 2 against the edge region of the roof opening D. The circumferential groove 13 serves to intercept and conduct water which collects on the surface of the roof 2 or which flows in the direction of the vehicle interior in the closed position of the roof 2 in spite of the sealing means in the edge region of the roof opening D. The channel 13 is provided in the opposite front corner region of the edge of the roof 2 with two water outlet connections 17, which are each located at the deepest point of the roof 2 in the closed position of the roof with reference to a horizontal plane and project from the corner region laterally outward of the vehicle and longitudinally forward of the vehicle and slightly downward in the vehicle height direction. Each water outlet connection 17 opens above a water guide of the lateral guide device, which will be described in more detail below.

As can be seen from fig. 5, the groove 13 acts from behind in the height direction on the edge region of the roof opening D, so that the roof 2 cannot be moved upwards. As can also be seen from fig. 5, the outer wall of the groove 13, which is firmly connected to the glass pane of the roof 2, in the closed position of the roof 2, rests against the underside of the edge region of the roof opening D and is offset outwardly relative to the webs 14. Thereby avoiding that water may overflow beyond the outer wall.

The roof 2 can be lowered by means of a control movement from the closed position according to fig. 5 and can be moved back in the longitudinal direction of the vehicle below the roof area 1 fixed to the vehicle. In its final position, also referred to as the open position, the roof cover 2 is positioned relative to the roof opening D according to fig. 7 and is therefore moved at least as far back as possible below the roof area 1 fixed to the vehicle. The control movement mechanisms each have functional components, which are functionally identical but are mirror-symmetrical to the vertical central longitudinal plane, on opposite sides of the roof 2, as seen in the transverse direction of the vehicle, and which are described in more detail below. As regards the functional components controlling the movement mechanism, only the left side in the normal direction of travel will be described. The description applies equally to the opposite right side. On opposite sides of the roof opening D, which are offset laterally outward in relation to the vehicle roof opening D, guide devices are provided, which are fastened to the vehicle and each have a guide rail profile 5 which is straight when viewed in the longitudinal direction, but which is curved slightly upward in the height direction. The guide rail profile 5 is provided with a water guide channel, not shown in detail, above which the corresponding water outlet connection 17 of the channel 13 of the roof 2 opens. The guide rail profile 5 furthermore has an upwardly open guide channel for the corresponding functional components of the control mechanism. The water guide channel, which can be identical to the guide channel for the functional component, is connected at the end by a connecting piece (not shown in detail) to a hose line, not shown, in the installed state ready for operation. The hose line leads through the body pillar of the body carrier 3 towards the vehicle underside. The end ends of the water guide channel and of the rear side of the guide channel of the guide rail profile 5 are closed.

The roof 2 has, on the opposite side, in each case a transverse extension 15 which is firmly connected to the edge of the roof 2 and is designed as an L-shaped corner profile. The laterally extending structure 15 extends laterally outwardly of the vehicle until it passes over the rail profile 5. Each laterally extending structure 15 is firmly connected, preferably screwed, to a plate-shaped beam profile 16. The movement Liang Bantiao, 16 is thus transmitted positively to the roof 2 in a rigid connection. Liang Bantiao 16 are arranged laterally spaced apart from the roof opening D and thus also laterally spaced apart from the roof 2 in the region of the rail profile 5.

Liang Bantiao 16 at the front hinge point, a guide slide 6 is provided, which is guided in a linear manner in the guide channel by means of a spherically embodied slide shoe. The guide slide 6 can also be moved slightly in rotation with the front end region of the beam profile 16 at the front hinge point about a pivot axis extending in the transverse direction of the vehicle, on the basis of the spherical, diamond-like shape of the slide shoe. The beam profile 16 is thus supported about the front hinge point and thus together with the guide slide 6, in addition to being movable in the longitudinal direction of the guide channel, also in a limited manner in a pivot plane which is braced by the vehicle vertical axis and the vehicle longitudinal axis. The beam profile 16 is also connected to the control lever 10 in a pivotable manner at the rear end region via a rear hinge point 7. The control rod 10 is coupled to a guide slide 12 in the region of the guide channel at a lower hinge point 11, in which the guide slide can be moved in a linearly movable manner. In the region of the rear hinge point 7, the lever end above the control lever 10 also has a rocker journal projecting laterally outwards in the transverse direction of the vehicle, which rocker journal is inserted into a rocker guide 9 fixedly positioned with the vehicle at the guide. The pivot of the rocker at the rear hinge point 7 of the beam profile 16 is not shown in detail, but can be seen schematically in fig. 2 to 4 in the region of the reference numeral 7. As can also be seen from fig. 2 to 4 and fig. 8 to 10, the rocker guide 9 has a guide section which is arranged vertically in the upwardly projecting control block 8 and which, by means of a circular arc curvature, is turned flush back in the longitudinal direction of the vehicle into a guide channel of the guide rail profile 5. The rocker pin is thus guided in a linearly movable manner either in the vertical guide section of the rocker guide 9 or in the circular-arc-shaped guide section or in the guide channel, whereby a positive control of the control lever 10 is obtained.

In the closed position of the roof 2, the pivot pin is located in the end region above the vertical guide section of the pivot guide 9. As soon as the guide slide 21 is now moved back along the guide channel of the guide rail profile 5, the guide slide 12 drives the lower hinge point 11 of the control lever 10, thereby also forcibly pivoting the rocker in the rocker guide 9 and thus pulling the rear hinge point 7 of the beam profile 16 back. The rear end region of the roof 2 is thus forced downward, wherein a slight pivoting of the beam profile 16 about the pivot axis of the guide slide 6 is simultaneously produced. Once the rear hinge point and the pivot pin of the beam profile 16 pass through the circular-arc-shaped guide section of the pivot guide 9 (fig. 3), the rear hinge point 7 descends to the level of the guide channel, so that the roof 2 also descends with its rear end in accordance with fig. 6. The front edge of the roof 2 is also at the level of the webs 14 of the edge region of the roof opening D according to fig. 6, so that the front outer wall of the channel 13 also acts on the webs 14 from behind in the longitudinal direction of the vehicle. However, as already explained, the outer wall is preferably elastically flexible due to the shaping of the elastomer material, so that the outer wall is guided past the webs 14 with short deformations when the guide slide 12 is moved further back. As soon as the guide slide 12 reaches the rear end region of the guide channel, as shown in fig. 4, the roof 2 is pivoted into its open position. As can be seen from fig. 4, the front guide slide 6 is also moved back here, since the control lever 10 pulls Liang Bantiao together with Liang Bantiao in a simple manner, thereby also moving the guide slide 6 back.

When the roof 2 should be pivoted back again from this open position into its closed position, the guide slide 12 is moved forward in the opposite direction, so that the control lever 11 in combination with the rocker guide 9 again passes through the opposite path. The rear hinge point 7 of the beam profile 16 is again forced upward in the rocker guide 9 to the upper end of the upper guide section. The positioning of the rocker guide 9 and of this control block 8 relative to the roof opening D is carried out in such a way that the rear hinge point 7 of the beam profile 16 is pressed upwards, thereby forcibly pressing the rear edge region of the roof 2 into the closed position again. The front edge region of the roof cover 2 is in contact with the front section of the web 14 of the edge region of the roof opening D. This is possible because the roof curvature of the guide device and thus the orientation of the guide channel 5 relative to the roof region 1 fixed to the vehicle is inclined, so that the displacement of the guide slide 6 of the rear hinge point 7 of the beam profile 16 forcibly guides the front section of the channel 13 and the front edge of the roof 2 in the forward driving movement in the height direction up to the height of the front section of the web 14 of the edge region of the roof opening D. The position of the guide slide 6 relative to the guide channel 5 corresponds in fig. 2 and 3 to fig. 5 and 6 with a corresponding positioning of the roof 2.

In order to move the two guide slides 12 synchronously into the opposing guide channels 5 of the two guide devices, a drive slide, not shown in detail, is associated with each guide slide 12, which drive slide is coupled to the respective guide slide 12. The movement of the drive slide thus also forcibly causes the movement of the guide slide 12. The drive slide is mounted in the guide 5 in a linearly movable manner parallel or coaxial to the guide channel of the guide rail profile 5 as is the guide slide 12. For driving the movement of the slide, a threaded cable 19 of the drive system 18 is provided, which is guided in the respective guide rail profile 5 and can be driven synchronously with one another by means of a suitable gear train and an electric drive motor of the drive system 18. The arrangement of the electrical drive unit, the gear train and the spiral cable guided in the hose or line can be seen clearly with reference to fig. 8 to 10.
