Description

Roof system

Technical Field

The invention relates to a roof system having a roof region which is fixed to a vehicle in a ready-to-operate installation state, which roof region has a roof opening which is open toward the interior of the vehicle and can be closed by a roof panel which in the closed position is fitted into the roof opening from below with reference to the vehicle height direction, and which roof panel has a circumferential, upwardly open groove on the edge side, into which groove a downwardly directed circumferential web of the edge of the roof opening projects in the closed position of the roof panel.

Background

Such a roof system is known from DE 10319783B 4. Known roof systems have a stationary roof region which is provided with a roof cutout. The roof cover fits into the roof cutout. The roof of the glass vehicle has an upwardly open groove at its edge region. In the installed state of the roof panel in the roof cutout, the web of the edge region of the roof cutout projects into this groove. The roof cover is mounted in the roof cutout from below, so that the groove of the roof cover acts on the web of the edge region of the roof cutout from behind in the vehicle height direction. In order to achieve a permanent connection of the seal between the roof panel and the edge region of the roof cutout, a sealing device is positioned in the region of the groove. The roof cover 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 beginning, which allows an opening function for the roof cover with simple means.

This object is achieved in that the roof cover is assigned a control movement by means of which the roof cover can be moved between a closed position and an open position, in which the roof cover is at least partially open at the roof opening, in which the roof cover is moved at least partially below a roof region fixed to the vehicle, downward in the vehicle height direction and rearward in the vehicle longitudinal direction. The solution according to the invention on the one hand enables a particularly safe support of the roof panel in its closed position upwards. This prevents the roof panel from possibly falling out of the roof opening upward, particularly in the event of a collision of the vehicle. The roof system can therefore achieve particularly good results in the usual compression tests for checking vehicle roofs. According to the invention, on the other hand, the roof cover can be moved into the open position despite the roof cover being safely supported in its closed position, whereby additional fresh air can be supplied to the vehicle interior. The control movement is designed in a simple manner such that the roof cover is moved only downwards and backwards from its closed position in order to at least partially open the roof opening. The solution according to the invention is particularly advantageously suitable for use in private cars. The invention can also be used with other types of vehicles, in particular in the form of different wheeled or rail vehicles.

In one embodiment of the invention, the control mechanism has two guide devices fixed to the vehicle for moving the roof, which guide devices extend in the longitudinal direction of the vehicle and are arranged at a distance from each other on opposite sides, viewed in the transverse direction of the vehicle, next to the roof opening. The guide device is therefore positioned laterally outside the roof opening, fixed to the vehicle. The dimensions of the roof opening are thus not impeded by corresponding guides positioned in the region of the roof opening.

In a further embodiment of the invention, a drive system is assigned to the control kinematics, by means of which a movement of the roof between the closed position and the open position can be driven. The drive system is preferably designed such that the control kinematics are 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 mechanism. Furthermore, the drive system has longitudinally extending tie rods and/or pressure rods for transmitting the drive force from the electric drive unit to the control kinematics. The respective tie and/or press rod can be formed by a flexible spiral cable, a bowden cable, a cable drive system or a flexible toothed rod.

In a further embodiment of the invention, the roof cover has, on opposite sides, in each case a transverse extension which, in the closed position, is positioned below the roof opening and extends beyond the edge of the roof opening in the vehicle transverse direction in the direction of the respective guide device. The expression "extends beyond the edge of the roof opening" here means that the transversely extending structure extends laterally outwardly along the edge region of the roof opening below the edge region in the closed position. As the transverse extension, 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. The laterally extending structure is form-stable and preferably consists of metal.

In a further embodiment of the invention, a beam profile extending along the respective guide is fastened to the respective transverse extension, which beam profile is connected to a further functional part of the control movement. The two beam profiles on opposite sides of the roof cover are thus connected to the roof cover in a secure and movement-transmitting manner by means of the respective transverse extension.

In a further embodiment of the invention, the beam profile has, as a functional part, at the front articulation point, a guide slide which is guided in a linearly movable manner in a guide rail of the guide device. The guide device is preferably formed on each side of the roof opening by a rail profile, which is preferably designed as an extruded profile with at least one guide channel that opens upward. The guide slide can have at least one sliding shoe or at least one rolling element in order to achieve a linearly movable guide in the guide rail of the guide device.

In a further embodiment of the invention, the guide slider is designed in such a way that the beam profile can additionally move slightly in rotation about a pivot axis extending in the transverse direction of the vehicle at the front articulation point. This allows a limited pivoting movement of the beam profile about its front pivot point 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 to lower or raise the rear hinge point from the closed position of the roof cover into the closed position of the roof cover. By means of this lowering or lifting movement of the rear hinge point, a slight pivoting movement is forcibly generated 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 spherical or diamond-shaped sliding shoe in cross section, so that a slight tilting movement of the sliding shoe and thus of the guide slide is achieved. The lifting mechanism is preferably realized by a mechanical positive guide mechanism.

In a further embodiment of the invention, a linear guide is coupled to the lifting device, which linear guide moves the beam profile longitudinally along the guide rail in the lowered functional position. The hoisting mechanism is responsible for lowering or lifting a hinge point at the rear of the roof cover. In order to be able to move the roof cover from the lowered intermediate position back into the open position at least partially into the area below the stationary roof, 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, which drive slide is coupled to a functional part of the control movement in order to bring about a synchronous parallel displacement of the opposite sides of the roof. The drive slide in each guide preferably drives a corresponding linear guide which forcibly drives the beam profile via the rear articulation point of the lifting means and the beam profile. The hinge point arranged in front of the beam profile therefore also moves with the guide slide, so that a parallel movement of the opposite side of the roof panel is possible.

In a further embodiment of the invention, the lifting mechanism has a rocker guide fixed to the vehicle in the region of the guide device and a control rod which is pivotably movably articulated at an articulation point behind the beam profile and which can be lowered and raised by means of a rocker journal in the rocker guide. The rocker guide fixed to the vehicle and the rocker pin define a positive control for the control rod in such a way that this control rod is positively lowered from at least the most upright possible position when the linear guide is moved and is drawn together by the linear guide in the lowered, flat position back in the longitudinal direction of the guide. The rocker guide preferably extends in the height direction at the level of the closed position and also in the longitudinal direction of the guide device, so that the control rod is positively guided over its entire movement path.

In a further embodiment of the invention, the control rod is connected with a guide slide of the linear guide with a rod end remote from the rear articulation point of the beam profile, the guide slide being guided in a guide rail of the guide device in a linearly movable manner. The guide slide is preferably assigned a drive slide of a drive system in a manner that allows for a transmission of motion. The guide slide is advantageously mechanically coupled to the drive slide, preferably in a form-fitting manner.

In a further embodiment of the invention, each guide device is assigned a water guide and the roof is assigned a water outlet nozzle assigned to the channel, which protrudes toward the respective guide device in order to discharge water which has intercepted the channel of the roof into the water guide of the guide. The roof cover preferably has at least one water outlet connection on each longitudinal side, so that water can be discharged from the channel into two opposing guide devices.

In a further embodiment of the invention, the curvature of the roof region fixed to the vehicle in the region of the roof opening and the orientation of the guide device at the height of the roof opening, viewed in the longitudinal direction of the vehicle, are aligned at an angle to one another such that the front edge of the roof panel strikes against the front edge section of the roof opening when the roof panel is moved longitudinally from the open position forward in the direction of the closed position. The roof panel and thus the beam profile therefore 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 or raised longitudinally forward relative to the plane of the guide device at the level of the roof opening.

Further advantages and features of the invention emerge from the claims and the subsequent description of a preferred embodiment of the invention illustrated by means of the drawings.

Detailed Description

According to fig. 1, a passenger car has a roof region which is connected to a windshield (shown on the left in fig. 1) in the longitudinal direction of the vehicle to the rear and which is equipped with a roof system which is described in detail below 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 fixed to the vehicle is firmly connected to the body support structure 3 of the passenger car. The roof region 1 fixed to the vehicle can be connected directly, in particular by gluing, to the respective roof rail and roof cross member of the body support 3. The roof region 1 fixed to the vehicle can alternatively be firmly connected, preferably adhesively bonded, to a support frame, which in turn can be fixed to the vehicle body support structure 3, where it is fixed to the respective roof-side longitudinal and transverse 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 fixed to the vehicle has a substantially rectangular roof opening D, which is defined by a circumferential edge region with a circumferential edge web 14 pointing downward in the vehicle height direction, approximately at the level of the front seat of the vehicle interior of the passenger car. In the closed position, the roof opening D is closed in a sealing manner by a roof panel 2, which in the present case is likewise made of glass and thus forms a glass roof panel. On the bottom side facing the vehicle interior, a light screening device, not shown in detail, is associated with the vehicle-fixed roof region 1 and roof region 2 in order to be able to screen the roof region 2 and the corresponding transparent glass surface of the vehicle-fixed roof region 1 from light.

As can be seen from fig. 2 to 7, the horizontal plane is curved over its entire longitudinal extent, as viewed in the longitudinal direction of the vehicle, in comparison with the fixed roof region 1 of the vehicle. The roof panel 2 fits in its closed position (see fig. 5) flush with the outside of the fixed roof region 1 of the vehicle and in line into the roof opening D. The roof region 1 fixed to the vehicle is curved upward not only in the longitudinal direction of the vehicle but also in the transverse direction of the vehicle.

The roof panel 2 has at its peripheral edge a peripheral groove 13 which is open toward the top and into which a peripheral web 14 of the edge region of the roof opening D projects in the height direction in the closed position of the roof panel 2. The webs 14 and/or the outer wall section of the groove 13 are designed to be slightly elastically flexible. The surrounding edge of the roof panel 2 furthermore has a surrounding sealing device, not shown in detail, which additionally seals the edge of the roof panel 2 against the edge region of the roof opening D. The circumferential groove 13 serves to intercept and guide water which collects on the surface of the roof panel 2 or flows in the direction of the vehicle interior in the closed position of the roof panel 2 despite the sealing arrangement in the edge region of the roof opening D. In the corner region of the edge of the roof panel 2 lying opposite in front of it, the channel 13 is provided with two water outlet nozzles 17 which, in the closed position of the roof panel, are each positioned at the deepest point of the roof panel 2 with reference to a horizontal plane and project from the corner region in the transverse direction of the vehicle outwards and in the longitudinal direction of the vehicle forwards and slightly downwards in the height direction of the vehicle. Each water outlet connection 17 opens above the 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 in the height direction from behind on the edge region of the roof opening D, so that the roof panel 2 cannot move upwards. It can also be seen from fig. 5 that the outer wall of the groove 13, which is firmly connected to the glass pane of the roof cover 2, rests against the underside of the edge region of the roof opening D in the closed position of the roof cover 2 and rests offset outwards with respect to the webs 14. Thereby avoiding that water may overflow beyond the outer wall.

The roof cover 2 can be lowered by means of a control movement from the closed position according to fig. 5 downwards and can be moved in the longitudinal direction of the vehicle backwards below the roof region 1 fixed to the vehicle. In its final position, also referred to as the open position, the roof cover 2 is positioned according to fig. 7 relative to the roof opening D and is therefore moved at least as far back as possible below the roof region 1 fixed to the vehicle. The control kinematics, as viewed in the transverse direction of the vehicle, each have functionally identical functional components on opposite sides of the roof 2, which are configured mirror-symmetrically to the vertical central longitudinal plane, and which are described in more detail below. As far as the functional components controlling the movement mechanism are concerned, only the side on the left in the normal direction of travel will be described. The description applies equally to the opposite right side. The opposite sides of the roof opening D, offset in the transverse direction of the vehicle from the roof opening D, are each provided with a guide device fixed to the vehicle, which has a guide rail profile 5 that is straight when viewed in the longitudinal direction, but is slightly bent 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 groove 13 of the roof cover 2 opens. The guide rail profile 5 furthermore has guide channels which are open at the top for the corresponding functional parts 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 via a connecting piece (not shown in detail) to a hose line, not shown, in an installation state ready for operation. The hose line is led out through the body pillar of the body support structure 3 to the vehicle underside. The end extremities of the water guide channel and of the back side of the guide channel of the rail profile 5 are closed.

The roof cover 2 has, on opposite sides, in each case a transverse extension 15 which is firmly connected to the edge of the roof cover 2 and is designed as an L-shaped angle profile. The transversely extending structure 15 extends in the transverse direction of the vehicle outwards as far as past the rail profile 5. Each transversely extending structure 15 is firmly connected, preferably screwed, to a lath-shaped beam profile 16. The movement of the beam web 16 is thus transmitted to the roof panel 2 by force in a rigid connection. The beam web 16 is arranged in the region of the rail profile 5 laterally spaced apart from the roof opening D and thus also laterally spaced apart from the roof cover 2.

The beam web 16 is provided at the front joint with a guide slide 6, which is guided in a linearly movable manner in a guide channel by means of a spherical sliding shoe. Due to the spherical, diamond-like shape of the sliding shoe, the guiding slider 6 can also move slightly in rotation with the front end region of the beam profile 16 at the front articulation point about a pivot axis extending in the transverse direction of the vehicle. The beam profile 16 is therefore mounted with limited pivotal movement about the front pivot point and therefore together with the guide slide 6, in addition to the longitudinal displaceability along the guide channel, also in a pivot plane which is spanned by the vehicle vertical axis and the vehicle longitudinal axis. The beam profile 16 is also connected to the control rod 10 at the rear end region in a pivotable manner via a rear hinge point 7. The control rod 10 is coupled at a lower hinge point 11 in the region of the guide channel to a guide slide 12, which can be moved in a linearly movable manner in the guide channel. In the region of the rear hinge point 7, the upper lever end of the control lever 10 also has a rocker pin projecting laterally outward in the transverse direction of the vehicle, which is inserted into a rocker guide 9 positioned fixedly with the vehicle at the guide. The rocker journal of the hinge point 7 behind the beam profile 16 is not illustrated 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 8 to 10, the rocker guide 9 has a guide section which is arranged vertically in the upwardly projecting control piece 8 and which is turned by means of a circular arc-shaped bend in the longitudinal direction of the vehicle rearward flush with the 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, in the circular-arc-shaped guide section, or in the guide channel, so that a positive control of the control rod 10 is achieved.

In the closed position of the roof panel 2, the rocker pin is located in the upper end region of the vertical guide section of the rocker guide 9. As soon as the guide carriage 21 now moves rearward along the guide channel of the guide rail profile 5, the guide carriage 12 drives the lower hinge point 11 of the control rod 10, as a result of which the rocker pin in the rocker guide 9 and thus the rear hinge point 7 of the beam profile 16 are also forcibly pulled rearward. The rear end region of the roof panel 2 is thus lowered forcibly downward, a slight pivoting of the beam profile 16 about the pivot axis of the guide slide 6 taking place at the same time. As soon as the rear hinge point of the beam profile 16 and the rocker pin pass through the circular-arc-shaped guide section of the rocker guide 9 (fig. 3), the rear hinge point 7 is lowered to the height of the guide channel, so that the roof panel 2 is also lowered with its rear end downward in fig. 6. The front edge of the roof cover 2 is then, according to fig. 6, also at the level of the web 14 in the edge region of the roof opening D, so that the front outer wall of the channel 13 also acts on the web 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 it is guided past the web 14 with a short deformation when the guide slide 12 is moved further rearward. As soon as the guide carriage 12 reaches the rear end region of the guide channel according to 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 rearward in this case, since the control rod 10 pulls the bar strip 16 away together in a simple manner, thereby also moving the guide slide 6 rearward.

When the roof panel 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, whereby the control rod 11, in conjunction with the rocker guide 9, again passes through the opposite path. The rear hinge point 7 of the beam profile 16 is again moved forcibly 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 piece 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 upward, as a result of which the rear edge region of the roof panel 2 is forcibly pressed into the closed position again. The front edge region of the roof panel 2 is in contact with a section of the front of the web 14 of the edge region of the roof opening D. This is possible because the roof curve 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 movement of the guide slider 6 of the rear hinge point 7 of the beam profile 16 forcibly guides the front section of the groove 13 and the front edge of the roof panel 2 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 in the forward driving movement. 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 the corresponding positioning of the roof panel 2.

For the synchronous displacement of the two guide slides 12 into the opposing guide channels 5 of the two guide devices, a drive slide, not shown in detail, is assigned to each guide slide 12, which is coupled to the respective guide slide 12. The movement of the drive slide therefore also forcibly causes a movement of the guide slide 12. The drive slide is mounted in the guide device 5, like the guide slide 12, parallel to or coaxially with the guide channel of the guide profile 5, so as to be linearly movable. For driving the movement of the slide, a threaded cable 19 of a drive system 18 is provided, which is guided in the respective guide profile 5 and can be driven synchronously with one another by means of a suitable gear mechanism and an electric drive motor of the drive system 18. The arrangement of the electric drive unit, the gear mechanism and the spiral cable guided in the hose or line can be clearly seen with reference to fig. 8 to 10.
