A canopy element (18) is arranged below the roof opening and is driven by at least one roof-mounted motor (22, 40) to make a sliding movement in order to selectively cover or uncover the roof opening. The or each motor drives at least one drive element (128, 130) for a rotary movement, which acts non-positively on a surface of the sky element in order to drive the sky element for the displacement movement.

Description

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

Such a generic vehicle roof is known for example from DE 37 06 141 C1, DE 195 13 971 C2 or EP 0 150 470 B1. In these known vehicle roofs it will be underneath a sliding and / or swiveling transparent cover arranged sky element via two pressure-resistant drive cables from an electric motor driven, the shaft of which carries a worm that drives a pinion, which in turn also the pressure-resistant drive cables are engaged. A disadvantage of such Sky drive is the high level of noise that occurs when the sky drive is operated arises because the drive cables grind in their guide channel over their entire length.

Furthermore, e.g. B. from DE 29 23 904 C3, sliding headliner known, when closed Lid are operated by hand and during the opening movement of the lid by this be taken along via a special mechanism. From EP 0 185 993 B1 is a Sliding headliner known with a driver mechanism, which ensures that the Sliding headliner by the opening movement of the cover in order to support the Ventilation function is opened a bit. The driver mechanism comprises two Racks and a pinion that meshes with both racks. According to one The first embodiment is the first rack on one of a rigid Drive cable powered drive carriage provided for the lid while the second Rack on the headliner itself is attached laterally. That in both racks engaging pinion, which is arranged between the two racks, is roof-fixed stored. Similar sliding headliner constructions are known from EP 0 754 583 A1 and  US 5,558,394. According to a second one described in EP 0 185 993 B1 Embodiment, the first rack is fixed to the roof, the second rack is also attached to the side of the sliding liner. That between the two Racks located and engaging in both racks is on the one of pressure-resistant drive cable driven drive carriage mounted for the lid. On Similar system is also known from DE 38 39 578 A1.

The disadvantage of these known hand-operated sliding roof systems is the low level Comfort and the risk that the operator when operating the sliding roof system distracted from traffic while driving.

From DE 20 32 144 B2 is a rack and pinion drive for a folding roof with fixed vehicles Racks known. From DE 33 10 502 C2 and WO 90/08668 it is known the cover of a vehicle roof on fixed racks.

From DE 43 20 393 C2 a pre-tensioned roller blind sliding liner is known, which in Roof-mounted gear racks engaging gears that are braked by means of a viscosity brake are led. It is a hand-operated system.

It is an object of the present invention to provide a vehicle roof with a movable To create a sky element that can be operated comfortably and safely and at operation is quiet, requires as few moving parts as possible and saves space during installation is.

This object is achieved by a vehicle roof as defined in claim 1.

In this solution according to the invention it is advantageous that only a minimum of moving It is necessary to share excessive noise during operation Grinding movements are avoided, only a small installation space in the direction of travel there is and yet a high level of comfort without unduly impairing the Attention of the operator is guaranteed.  

In an advantageous development of the invention it is provided that the or each Drive element acts on the top or bottom of the headliner. this makes possible a particularly favorable spatial arrangement of the drive system.

According to a preferred embodiment, the or each drive element is a gear formed, which each with a provided on the roof element rack Intervention stands. This represents a particularly robust design with high reliability.

According to an alternative preferred embodiment, the or each drive element formed as a drive roller that with the corresponding surface of the sky element in Frictional intervention. This represents a particularly simple embodiment, since, for. Legs Rack is dispensable.

According to a further preferred embodiment of the invention, there are two drive elements provided, which are each provided at one end of a connecting shaft and from which Connection shaft are driven. This ensures an even application of force, to keep the risk of jamming low.

The connecting shaft can be at one end or at both ends of one Drive motor to be driven, or it can be from one in its central section arranged motor are driven. Preferably the rotation of the or each Drive elements geared down with respect to the rotation of the or each drive motor, this can be done in that between the or each motor and the connecting shaft Reduction gear is switched.

The following are three embodiments of the invention with reference to the accompanying Drawings explained in more detail. Show it:

Figure 1 is a plan view of a vehicle roof according to the invention in a first embodiment.

Fig. 2 is a corresponding view of a second embodiment;

Fig. 3 is a corresponding view of a third embodiment; and

Fig. 4 shows a section along the line IV-IV of FIG. 1,.

Referring to FIG. 1 and 4, a roof opening 12 is provided in a fixed roof skin 10, below which a roof module 14 is attached, which has a lid 16 and a sliding headliner 18. The roof module 14 is designed as a sliding-lifting roof, that is, the cover 16 can be extended on the one hand from the closed position shown in FIG. 4 with its rear edge in order to provide a ventilation function, while on the other hand it can be opened from the position shown in FIG. 4 The closed position can be pushed back under the fixed roof skin 10 in order to completely expose the roof opening 12 . The lid 16 is made of transparent material, e.g. B. glass. The sliding headliner 18 is made of non-transparent or semi-transparent material in order to prevent outside light falling through the closed or partially opened cover 16 from entering the vehicle interior 20 . For this purpose, the sliding headliner 18 is mounted in the roof module 14 so as to be displaceable in the longitudinal direction of the roof. The sliding movement of the sliding headliner 18 takes place via an electric motor 22 which drives a reduction gear 24 , which in turn drives a connecting shaft 26 which is arranged on the top of the sliding headliner 18 and extends transversely to the latter. The shaft of the motor 22 (not shown) is coaxial with the connecting shaft 26 .

The connecting shaft 26 carries at its ends a drive roller 28 and 30 , respectively, which are in frictional engagement with the upper side 32 of the sliding headliner 18 in order to move this in accordance with the actuation of the motor 22 by the operator in the roof longitudinal direction in order to selectively the transparent cover 16 cover from below. In the arrangement shown, the force is introduced into the sliding headliner 18 evenly on the two side edges near the guide, so that the risk of canting is minimized. If, due to good lateral guidance of the sliding headliner 18, the risk of canting is low anyway, the drive roller 30 and thus also the connecting shaft 26 can be omitted, so that in this case the force is applied only on one side via the drive roller 28 .

An alternative embodiment is shown in FIG. 2, in which, in contrast to the embodiment described above, the motor is not arranged laterally at one end of the connecting shaft, ie at the edge of the sliding headliner 18 , but is provided in a central region of the connecting shaft 26 in a roof module-fixed manner . The electric motor 122 is integrally provided with a gear in order to drive the connecting shaft 26 , which, as in the first embodiment, carries a drive roller 28 and 30 at both ends thereof. Here too, with corresponding lateral guidance of the sliding headliner 18 , one of the two drive rollers can be dispensed with. The motor / transmission unit 122 is preferably arranged in the middle of the connecting shaft 26 or the sliding headliner 18 .

In Fig. 3 a third embodiment of the roof module 14 is shown, in which the frictional connection between the sliding headliner 18 and the drive motor or the drive motors by means of gear / rack engagement. The basic arrangement is similar to that shown in FIG. 1, ie an electric motor 22 with an upstream gear 24 is arranged on the side of the sliding headliner 18 in a module-fixed manner coaxially with a connecting shaft 26 at one end. In addition, however, a second motor 40 with a correspondingly upstream transmission 42 is arranged opposite to the motor 22 and the transmission 24 at the other end of the connecting shaft 26 coaxially to the latter, in order to ensure an additional introduction of force into the connecting shaft 26 . However, this additional motor 40 with associated gear 42 is optional. In order to reduce the installation width of the roof module 14 , in deviation from the coaxial arrangement described so far, one or both of the motors 22 , 40 can be angled by 90 ° with respect to the connecting shaft 26 (in FIG. 3 at 22 'or 40 ' with dash-dotted lines) Lines indicated). The connecting shaft 26 carries at its two ends a gear 128 , 130 , which is in engagement with a rack 132 or 134 , which are provided on the top in the lateral edge region of the sliding headliner 18 . The racks 132, 134 may be formed as separate pieces and be attached in accordance with the sliding liner 18, or may be directly attached to the sliding headliner 18 is injection-molded, which is an economical solution.

The described invention is advantageous in that in the case of an electric drive of the Heaven element slope cables commonly used can be omitted and by the  low number of moving parts a noise reduction is achieved. Also allowed the drive according to the invention has a high travel speed and enables that Canopy element can be opened further forward because the drive motors are not in Direction of travel must be arranged in front of the movable sky element.
