Description

vehicle roof

The invention relates to a vehicle roof, in particular a passenger car, with the features of the preamble of claim 1.

It is always desirable, in the case of vehicle roofs which have an optionally divided, transparent roof section extending over the entire vehicle length, to provide a shading device in the form of a roller blind or the like for protection against solar radiation. Known roller blind systems require expansive trim parts, which in turn can severely limit the available roof clearing surface. Large extension lengths of a rolloartigen Abschattelementes also require a guide in the vertical direction even with only slight roof curvature. Also, the selection of a particular section to be shaded is limited since the winding shaft is usually received by the roof structure.

A vehicle roof of the aforementioned type <is known for example from DE 103 22 709 B3 and can be used in this case in a passenger car designed as a so-called Van. The known vehicle roof comprises four transparent roof sections, which are arranged in pairs over the front area of the vehicle interior and above the rear area of the vehicle interior. The transparent roof sections can each be shaded with a roller blind-like cover element, which are each mounted on a winding shaft extending in the vehicle transverse direction. At their end facing away from the winding shaft, the cover elements each have a pull bar, which is mounted in lateral guide rails. leads, which are associated with the respective transparent roof section. In a between the pairs arranged right and left, transparent roof sections lying in the vehicle longitudinal direction extending area a console is formed on the roof underside, which can be provided with storage boxes and the like.

Furthermore, DE 103 45 711 A1 discloses a vehicle roof headliner, on which a bracket extending in the vehicle longitudinal direction is formed in the front central region, which console can be equipped with functional elements and the like.

The invention has for its object to provide a vehicle roof, which is provided with a flexibly applicable Abschatteinrichtung for a transparent roof section.

This object is achieved by the vehicle roof with the features of claim 1.

The essence of the invention is thus to provide a vehicle roof with a roller-type Abschatteinrichtung, which is equipped with a movable winding shaft. It is thus possible to move the front and the rear bearing point of the Abschatteinrichtung. One of the bearing points is defined by the drawbar and the other bearing point is defined by the winding shaft.

By moving the bearing point or the bearing points, which is done by moving the winding shaft and / or the Zugspriegels, the transparent roof section can be flexibly shaded, for example, only in a specific selected area. The vehicle roof according to the invention is designed in particular as a roof module, which can be provided in the fully configured state at an automobile manufacturer on a production line and can be placed on a corresponding roof frame.

A preferred embodiment of the vehicle roof according to the invention is designed such that a functional box which can be displaced in the guide devices forms a housing for a winding shaft of the roller-type shading device. There is thus no separate housing or no separate cassette for the winding shaft, which is biased in particular in the winding direction. By integrating a roller blind system in a movable roof function box, the required cladding area is reduced.

It is conceivable, of course, to provide a cassette or the like as a housing for the winding shaft and slidably mount in the guide means.

The function box may in particular comprise a storage compartment and / or also electrical devices. The electrical devices include, for example, a luminaire, a vehicle interior lighting and / or a display of a multimedia system and / or a navigation system.

A specific embodiment of the vehicle roof according to the invention comprises a transparent roof section which extends centrally over substantially the entire roof length and is optionally interrupted by a cross member in the amount of B pillars of the vehicle body. In this case, the vehicle roof preferably comprises two roller-type shading devices for the transparent roof section, each with a roller blind, one of which is mounted on a front, integrated in the function box. ckelwelle is mounted and can be pulled out in the direction of the vehicle front and the other is mounted on a rear, integrated in the function box winding shaft and extendable towards the rear of the vehicle. Both roll-like Ab- Schatteinrichtungen each have at their free end on a guided in the lateral guide means Zugspriegel and are each guided by a slot of the function box. Such a design of a vehicle roof allows an extremely flexible shading of the transparent roof section, which can be adjusted by appropriate positioning of the functional box and the respective Zugspriegel the roller-type Abschatteinrichtungen. The displacement of the function box and the operation of the roller-type Abschatteinrichtungen can be done manually or by electric motor.

Furthermore, a reduction of a guide in the vertical direction is possible in particular with long extension paths of the roller-type Abschatteinrichtungen compared to a design with only one roller blind-type section device, which is particularly important for minor roof curvature of importance.

The functional box, which can be guided on rollers or the like, is preferably provided with a braking device, which is released when the functional box is moved. Also, the function box or other storage device for the winding shaft (s) with front and rear stops in the guide means cooperate.

Further advantages and advantageous embodiments of the article according to the invention are the description, the drawings and the claims removed.

An embodiment of a vehicle roof according to the invention is schematically simplified in the drawing and will be explained in more detail in the following description. It shows:

1 is a perspective interior view of a motor vehicle with an inventively designed vehicle roof. and

2 shows a schematic and central longitudinal section through the vehicle roof of the motor vehicle according to FIG. 1.

In Fig. 1, a motor vehicle 10 is shown, which is designed as a so-called van and thus has a vehicle roof 12 which extends between so-called A-pillars 14 and so-called D-pillars 16. The vehicle roof 12 comprises a transparent roof section 18, which extends essentially over the entire length of the vehicle roof 12 and over approximately one third of the width of the vehicle roof 12 and is formed from a polycarbonate pane. As can be seen in FIG. 2, the transparent roof section 18 is interrupted approximately centrally by a cross member 20 extending in the vehicle transverse direction.

The transparent roof section 18 is surrounded by a substantially rectangular frame 22, for example made of aluminum, whose legs extending in the vehicle longitudinal direction are each designed as guide rails 24A and 24B. The guide rails 24A, 24B extend substantially over the entire length of the transparent roof section 18.

In the guide rails 24A, 24B designed as a storage box function box 26 is guided displaceably according to a double arrow, which has on its underside a flap 28, via which a storage space is accessible. For guidance in the guide rails 24A and 24B, the function box 26 has lateral rollers 30 which are not provided with a cooperating brake device, which is released in a manual displacement of the function box 26 in the vehicle longitudinal direction.

Furthermore, the function box 26 serves as a housing for a front winding shaft 32 and a rear winding shaft 34, which respectively serve to wind a roller blind 36 of a front rolloartigen Abschattelementes or a roller blind 38 of a rear rolloartigen Abschattelementes and this each by means of a Bourdon tube or the like in the winding are biased.

The two roller blinds 36 and 38 are each made of a textile fabric, which is substantially opaque.

The front roller blind 36 has at its front, the winding shaft 32 remote from the end of a front Zugspriegel 40, which is guided with its ends in the guide rails 24A and 24B. The rear roller blind 38 has at its rear, the rear winding shaft 34 remote from the end of a rear Zugspriegel 42, which is also guided with its ends in the guide rails 24A and 24B.

For manual actuation, the two cover elements 34 and 36 each have an actuating tab 44 and 46, respectively.

To move the function box 36, a slight upward pressure is exerted manually on the function box 26 so that the braking device of the rollers 30 is released and a displacement of the function box in the direction of the vehicle front or rear of the vehicle can take place. The extension and retraction of the two roller blinds 36 and 38 takes place in a manual manner Attack on the respective actuating tab 44 and 46 or on the respective drawbar 40 and 42, respectively.
