Description

The invention relates to a vehicle roof with a cover and a storage device that movably supports the cover on its two side areas by means of a front storage unit and a rear storage unit on a longitudinal guide of a roof side frame and adjusts it between a closed position in a roof opening and an open position.

From the DE 10 2006 062 543 A1 a generic vehicle roof with an adjustable cover has become known. A front bearing unit of the cover has an opening lever which, on the one hand, pivots the cover on its front area in a pivot joint and, on the other hand, is pivotally mounted on its rear end on a slide that is slidably mounted on a longitudinal guide. In its closed position, the cover is arranged in a roof opening, a gap between the cover and the roof opening being sealed by means of a seal. If, however, water passes the seal through the gap inwards, especially in the front side area of the cover in the area of the opening lever, this water can hit the swivel joint and / or the opening lever, especially when the vehicle is in a sideways inclined position on an inclined surface drip and from there get into a dry area of a roof side frame on the vehicle roof.

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 discharge of water entering at the side edge of the cover.

This object is achieved according to the invention in the vehicle roof mentioned at the outset in that a water drainage device is arranged on the front storage unit and / or that a water drainage device is arranged on the rear storage unit, the respective water drainage device supplying water that drips from the cover side edge to the respective storage unit a wet area of the roof side frame.

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

Even with the lid closed, it is not entirely excluded that water penetrates inward or downward to a certain extent from the top of the roof between the side edge of the lid and the roof surface adjacent to the roof opening or a seal arranged thereon, e.g. B. in heavy rain or in a car wash. The water that has penetrated runs down the cover side edge, for example on a panel arranged on the cover side edge, and usually drips into a wet area of the vehicle roof or a roof side frame arranged underneath. If the vehicle is, for example, in a lateral inclination of z. B. 15 ° inclination when the penetrated water is still on the lid side edge, z. B. when parking on a sloping surface, or occur when cornering such centrifugal forces that let the water droplets drip down at an angle, the dripping water can get to the front storage unit, the rear storage unit or both storage units and can from the respective storage unit in the Drip or run off the dry area adjacent to the wet area. By means of the water drainage device according to the invention, water which drips from the cover side edge to at least one of the two storage units can be reliably drained to a wet area of the roof side frame. Any liquid that can penetrate from the vehicle roof and over the edge of the lid is referred to as water. The at least one water guiding device contains, for. B. a guide element and can also have an upstream water collection device.

It can expediently be provided that the front storage unit has a release lever and / or that the rear storage unit has a release lever and that the water drainage device is arranged on the respective release lever and drains water that drips from the cover side edge towards the respective release lever to the wet area of the roof side frame .

Furthermore, it can be provided that the respective opening lever supports the cover by means of a swivel joint, which is arranged on the cover on the underside of the cover inward of the lid side edge, so that the respective opening lever when moving the cover from its closed position into an open position pulls the cover over the swivel joint relative to the longitudinal guide moved and that the water drainage device is arranged on the respective pivot joint and drains water that drips from the lid side edge to the pivot joint to the wet area of the roof side frame.

The water drainage device can be formed in different designs. It is particularly preferred that the water drainage device is arranged or formed on a bearing bush of the pivot joint. This bearing bush supports a bearing pin of the swivel joint on the cover or on a cover component such as a cover support or the like. In particular when the swivel joint, which connects the opening lever to the lid or the lid carrier, is very close to the side edge of the lid under the lid in the transverse direction is arranged, such a water drainage device can advantageously be used. Such an arrangement of the swivel joint can be provided if a compact and space-saving design of the lateral front bearing unit is desired in the transverse direction of the roof. The bearing bush is expediently an injection-molded plastic part, but can also be made of metal or a composite material with sliding bearing properties. The water drainage device can be molded onto it or attached to it as a separate component.

On the other hand, the water drainage device can also be formed on an extrusion coating of the opening lever. The encapsulation, z. B. a plastic overmolding made of polyurethane (PU) or polyoxymethylene (POM), forms a bearing bush of the swivel joint and supports a bearing pin of the swivel joint on the cover or another cover component according to the preceding embodiment. The extrusion coating is formed at least in the area of a bearing opening of the opening lever through which the bearing pin extends.

According to a preferred embodiment, it is provided that the water drainage device is a component that protrudes laterally from the pivot joint or from the bearing bush. Such a component is z. B. a channel or discharge channel or a tongue, in particular with a concave shape in cross-section for improved collection and drainage of the water. Such a component has a guide surface which protrudes outwards laterally or in the transverse direction of the roof. The guide surface or the component carrying the guide surface protrudes laterally in the axial direction of the bearing bolt, in particular below the bearing pin. In this way, the water hitting the swivel joint can be completely collected and drained off. In particular, the water drainage device or the component described above opens out above the wet area or an outer channel of the roof side frame which forms or has the wet area. The water drainage device or the component extends so far into the wet area that it is ensured that water is reliably drained into the wet area in the usual cases.

According to a further preferred embodiment it is provided that a wind deflector device is arranged on the vehicle roof, which in particular represents a network wind deflector. An extension arm of a wind deflector bracket of the wind deflector device is arranged in each case laterally inward of the deployment lever. A net of the wind deflector device is attached on the one hand to the extension arm and on the other hand to the roof side frame between the wet area and a dry area arranged inwardly thereof or also in the wet area. When the lid is closed, the net is partially or completely taken up in the dry area. The water drainage device keeps dripping water from moistening or wetting the network.

In the case of a vehicle roof of the prior art without a water drainage device, water dripping onto the bearing unit or onto the pivot bearing can run down from this or over the extension arm and continue to run or drip onto the network and can then also moisten or wet the rest of the network. When the cover is open and the wind deflector bar is open, water can splash into the vehicle interior from the tensioned and humidified network arranged in the air flow, especially when the vehicle is in motion.

The water drainage device according to the invention, on the other hand, conducts water into the wet area even when the vehicle is in unfavorable positions and thus keeps it safely away from the network. This prevents the disadvantages mentioned above from occurring.

If a screen is expediently arranged or molded on the side edge of the lid, which extends down to the respective bearing unit and in particular approximately to the pivot joint or in front of the pivot joint, water dripping off the screen is diverted from the water drainage device into the wet area. Such a diaphragm can be provided for optical and / or fluidic reasons. The distance between the panel or a lower panel edge from the swivel joint is expediently small, in particular with regard to a compact design.

Consequently, the water drainage device can reliably drain water that penetrates the cover side edge between the cover and a roof flange delimiting the roof opening even when the cover is closed, in particular also in the case of a net wind deflector arranged on the vehicle roof.

The longitudinal guides or the guide rails and the bearing units of the cover with the two water drainage devices are provided on the vehicle roof on both sides and symmetrically to the roof opening or to the vehicle longitudinal axis.

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, on which frame and bearing parts can be attached or molded.

The outer canal 33 represents a wet area 35 in which the penetrated water is collected and via lateral drainage pipes 36 is discharged. The longitudinal guide 8th on which the bearing slide 20th the rear bearing of the opening lever 12th Is slidably guided is in the outer channel 33 and thus in the wet area 35 arranged. The inner channel 32 provides a drying area 37 or is part of a dry area 37 .

With the lid closed 2 is the swivel joint 14th in one position (see 4th ), in which the opening lever 12th on the swivel joint 14th above the partition 34 is arranged. The shoulder head 28 of the bearing pin 24 lies only slightly inwards from the side edge of the lid 23 . An aperture 38 is on the edge of the lid 23 at least in the area of the opening lever 12th molded, z. B. as part of the PU foam lining 19th . The aperture 38 extends almost to the swivel axis 39 of the bearing pin 24 and thus covers approximately the upper half of the bearing pin 24 sideways. The aperture 38 is above the wet area 35 arranged.

If especially with the lid closed 2 Water from the top of the roof between the edge of the lid 23 and one the roof opening 3 limiting roof flange 40 or one on the roof flange 40 arranged seal 41 penetrates inwards or downwards and on the panel 38 to the lower edge of the panel 42 flows down, it is from the lower edge of the aperture 42 Water dripping down usually into the under the lower edge of the panel 42 arranged wet area 35 reach. When the vehicle assumes a position inclined to the right, e.g. B. when parking on a sloping surface, water can come off the cover if it is tilted sufficiently 38 or from the lower edge of the panel 42 on the shoulder head 28 of the bearing pin 24 of the swivel joint 14th drip and from the bearing pin 24 on the opening lever 12th and from this via the partition 34 away into the inner dry area 37 drops.

According to the invention is a water drainage device 43 provided the penetrated and from the aperture 38 to the swivel joint 14th dripping water in the wet area 35 dissipates and thus prevents this water directly or indirectly in the dry area 37 can get.

The water drainage device 43 has a guide surface 44 which catches and drains off dripping water. The guide surface 44 is z. B. from an approximately tongue-shaped wall 45 on the bearing bush 26th educated. The guide surface 44 or the wall 45 is on the covenant 31 the bearing bush 26th attached with which the bearing bush 26th axially at the shoulder head 28 of the bearing pin 26th is present. The guide surface 44 or the wall 45 is - based on the ring shape of the covenant 31 - roughly in the lower half of the federal government 31 the bearing bush 26th molded and extends from this covenant 31 from the outside, preferably in the manner of an upwardly open spout. The component that takes over the water collection and drainage can also be referred to as a collecting and drainage channel and can also have the shape of a tongue that is flat or concave in cross-section. The guide surface 44 is also formed, for example, in the form of a lateral surface of a truncated cone.

The guide surface 44 extends so far in the transverse direction from the pivot bearing 14th or the bearing pin 26th laterally outward that on the bezel 38 running down water, which both when the vehicle is inclined and when cornering under the action of centrifugal forces, is inclined inwards on the swivel bearing 14th can impinge on the guide surface 44 always in the outer canal 33 or in the wet area 35 will drain.
