Abstract

A blind assembly for a transparent roof section of a motor vehicle is proposed, comprising a blind element that can be adjusted between a blind position and an open position, and having guide rails (22A, 22B) fixed to the roof provided at the lateral edges of the blind element relative to the longitudinal center plane of the roof, the guide rails laterally delimiting the transparent roof section and having channels (24) in a plane above the blind element, in which luminous elements are arranged, which illuminate the blind element from above. Furthermore, a drive device is proposed, which is actuated when the blind element is adjusted so that the luminous elements are blocked relative to the underside of the blind assembly in the opened or partially opened state of the roof section.

Description

Technical Field

[0001] The invention relates to a covering arrangement for a transparent roof section of a motor vehicle. Background Art

[0002] Such a blind assembly is known from the publication DE 10 2014 108 119 A1 and is implemented as a roller blind assembly, which includes a roller blind as a blind element, which can be adjusted between a blind position and an open position. In the blind position, the transparent roof section is completely occupied by the roller blind. In the open position, the roller blind at least partially opens the transparent roof section. The roller blind is guided in guide rails fixed to the roof at the edges lateral to the longitudinal center plane of the roof, and the guide rails laterally define the boundaries of the transparent roof section. The lateral guidance of the roller blind can keep the roller blind taut in the transverse direction of the roof in the area where the roller blind is unwound from the roller blind. The blind assembly also includes a lighting device, which has a light-emitting part, which is received by a corresponding channel of the guide rail, and the channel is located in a plane arranged above the blind element. The shield element can be illuminated from above by means of the lighting element, thereby generating a light pattern on the shield element that can be seen from the vehicle interior. However, when the shield element is adjusted to the open position, there is the risk that the light that is emitted directly into the vehicle interior when the lighting element is activated may be disturbing to the passengers. Summary of the Invention

[0003] The object of the present invention is to provide a screen arrangement of the type mentioned in the introduction, in which the lighting element can be operated in any position of the screen element without the risk of dazzling or disturbing the passengers.

[0004] This object is achieved by a shielding assembly having the features according to the invention.

[0005] In other words, the shade assembly according to the present invention is provided with a drive device that ensures that the light-emitting element cannot directly shine into the vehicle interior because it is blocked in the opened or partially opened state of the roof section, that is, when the shade element is adjusted to the open position. This prevents direct illumination into the vehicle interior. In other words, the light-emitting element, which in particular constitutes a light conductor, is not visible to the passengers in the position of the shade element. This prevents the light-emitting element from shining into the vehicle interior in a disruptive manner when the roof section is opened or partially opened. Of course, in a specific embodiment, it is conceivable that the light emitted by the light conductor shines obliquely through the opened section into the vehicle interior without being disruptive to the passengers or directly striking them.

[0006] In a particular embodiment of the shade assembly according to the present invention, the drive device drives the light-emitting element so that it moves within the channel of the associated guide rail when the shade element is adjusted. In other words, in this embodiment, when the shade element is adjusted to the open position, the light-emitting element is moved out of the passenger's field of vision.

[0007] In a particular embodiment of the shade assembly according to the present invention, the drive mechanism includes a coupling mechanism between the shade element and the light-emitting element. The coupling mechanism displaces the light-emitting element via the shade element itself and removes it from the passenger's field of vision when the shade element is adjusted to the open position. Alternatively or additionally, a separate operating element may be provided, which is part of the drive mechanism and acts on the light-emitting element when the shade element is adjusted.

[0008] In an alternative embodiment of the shielding assembly according to the present invention, the drive device drives a shielding plate for the lighting element, which is moved before the lighting element when the shielding element is adjusted from the shielding position to the open position.

[0009] The drive device for driving the sunshade can specifically include a coupling device between the shielding element and the sunshade. The movement of the shielding element is then directly transmitted to the sunshade via the coupling device. It is also conceivable to additionally or alternatively provide a separate operating element that is part of the drive device and is driven when the operating element is adjusted.

[0010] The sun visor, which can be moved in front of the light element, can be a material strip made of opaque material, guided in a separate guide track of the associated guide rail. It is also conceivable that the sun visor surrounds the light element in the manner of a longitudinally slotted hose and is pulled or moved onto the light element for light blocking. When the shielding element assumes its blocking position, completely covering the transparent roof section, the sun visor exposes the light element. The sun visor is preferably received in a storage space, which can be formed by a guide device. The sun visor can also be arranged as a roll on a winding device.

[0011] The blind element of the blind assembly according to the invention is in particular a roller blind which is provided with a tensioning support and which is wound into a roller blind roll in its open position. It is also conceivable that the blind element is designed as a fabric web which, when adjusted to the open position, enters and is diverted into a receiving space in the relevant vehicle roof.

[0012] In the embodiment of the shielding element as a roller blind, the coupling device connected to the light or the sunshade is preferably connected to the tensioning support, ie the tensioning support also drives or carries with it the light or the sunshade. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] Further advantages and advantageous embodiments of the subject matter of the invention can be gathered from the description, the drawings and the claims.

[0014] An embodiment of the blind assembly according to the invention is schematically and simplified in the drawings and is explained in detail in the following description.

[0020] Figure 6 Shown along Figure 5 The line VI-VI in the section is cut according to Figure 5 Cross-sectional view of the shading component. DETAILED DESCRIPTION

[0021] exist Figure 1 1 shows a vehicle roof 10 of a passenger car (not shown in detail here), which has a roof section 12 that can be closed by means of a transparent cover element (not shown in detail) of a roof opening system. Roof section 12 can be at least partially opened by moving the cover element. Alternatively, the vehicle roof can also be designed without a movable cover element, that is, as a purely fixed roof. In this case, the vehicle roof includes a transparent fixed roof element that forms the transparent roof section and is connected to the vehicle body.

[0022] For shielding the roof section 12 , which is a transparent roof section regardless of the position of the roof covering element, the vehicle roof 10 comprises a roller blind assembly 14 as a shielding assembly, which comprises a roller blind 16 made of a foldable or windable material as a shielding element.

[0023] The roller blind 16 has a tensioning arm 18 at its free end. By driving the tensioning arm, the roller blind can be adjusted between a blocking position, in which the roller blind completely covers the roof section 12, and an open position, in which the roller blind at least partially opens the roof section 12. The roller blind 16 can be wound up at its edge facing away from the tensioning arm 18 into a roller blind roll 20, which is arranged, in particular, on a winding shaft extending in the transverse direction of the vehicle. When the tensioning arm 18 is released or moved toward the winding shaft, the roller blind 16 automatically winds up into the roller blind roll 20.

[0024] The roller blind 16 and the tensioning arm 18 are guided on both sides relative to the vertical longitudinal center plane of the roof in guide rails 22A and 22B, respectively, which are fixed to the roof and extend along the lateral edges of the roof section 12 or laterally delimit the roof section. The guide rails 22A and 22B can be components of a roof opening system (not shown in detail) or can also be assigned solely to the roller blind assembly 14.

[0025] For operation, the roller blind assembly 14 can have a drive motor which drives the tension arm 18 via a drive cable (not shown in detail). Alternatively, the roller blind assembly 14 can also be operated purely manually, specifically by manually moving the tension arm 18 in the longitudinal direction of the roof in the guide rails 22A and 22B.

[0026] The roller blind 16 is made of a material that has a lower side facing the vehicle interior and an upper side facing the vehicle surroundings and has a certain degree of transparency. A layer of phosphorescent or fluorescent paste can be applied to the upper side. It is also conceivable that the material of the roller blind 16 comprises a woven light-effect material or the like.

[0027] As especially by Figure 2 and 3 As can be seen, the guide rails 22A and 22B each have a channel 24 extending in the longitudinal direction, in which a light conductor 26 is received. The channel 24, which is located in a plane arranged above the roller blind 16, is open toward the roller blind 16, so that light that can be coupled into the corresponding light conductor 26 by means of the LED assembly 28 can be output toward the roller blind 16, thereby generating a light pattern on the roller blind 16 that is visible from the vehicle interior.

[0028] In order to shade the lateral areas of the light conductors 26 that are located near the section of the roof section 12 that is released by the roller blind 16, the roller blind assembly 14 has a sunshade 30 for each of the two light conductors 26. The sunshade is designed in the form of a longitudinally slotted hose and is guided with its longitudinal edges in guide rails 32 and 34 of the associated guide rail 22A or 22B. The sunshade 30 is provided with a drive that includes a coupling device 36, which is fastened to the sunshade 30 on the one hand and connected to the extension bracket 18 of the roller blind 16 on the other hand.

[0029] When the roller blind 16 is operated by moving the extension arm 18 in the longitudinal direction of the vehicle roof, the sun visor 30, connected to the extension arm 18 via the coupling device 36, moves on the guide rails 22A and 22B so that the area of ​​the light conductor located near the roller blind 16 is exposed, and the area of ​​the light conductor 26 located in the area of ​​the roof section 12 exposed by the roller blind 16 is blocked. In other words, when the extension arm 18 is moved toward the rear of the vehicle, the sun visor 30 is pulled rearward into the guide rails 22A and 22B. In the blocking position of the roller blind 16, the sun visor 30 is arranged at the head side of the guide rails 22A and 22B and is received by corresponding storage spaces or storage guides (not specifically described here).

[0030] Of course, vehicle roofs are also conceivable in which a roller blind is extended at the rear of the vehicle to cover the transparent roof section, and the sun visor is then pulled into the guide rails from the rear in the direction of the vehicle front, with the storage space or storage guide for the sun visor being arranged on the rear side of the guide rails.

[0031] exist Figure 4 An alternative embodiment of the roller blind assembly according to the invention is shown in FIG. 1 , which largely corresponds to the embodiment according to Figure 2 and 3 The roller blind assembly is different from the roller blind assembly in that it comprises a strip-shaped visor 30 which is guided in guide rails 32 and 34 of the associated guide rail 22A or 22B and corresponds to the roller blind assembly according to the embodiment of the present invention. Figure 2 and 3 In the embodiment of the present invention, the lighting elements, each formed by a light conductor 26, are shielded in the area adjacent to the section of the roof section 12 opened by the roller blind 16. The area of ​​the light conductor 26 adjacent to the roller blind 16 can emit light onto the roller blind 16 when the LED assembly 28 is activated. As a result, even when the roof section 12 is opened or partially opened, the passengers are not disturbed by the light emitted by the light conductor 26.

[0032] In addition, according to Figure 4 The embodiment corresponds to the Figure 2 and 3Implementation method, therefore refer to the description related thereto.

[0033] exist Figure 5 and 6 , a roller blind assembly 14' is shown. This assembly also includes a roller blind 16 that can be adjusted between a blocking position, in which the blind covers the roof section 12, and an open position, in which the blind at least partially opens. The roller blind 16 and the open bracket 18 are also guided in lateral guide rails 22A and 22B. The guide rails 22A and 22B each have a channel 24 in a plane above the roller blind 16, into which a light conductor 26 is received as a light source. Light from an LED assembly 28 can be coupled into each light conductor 26.

[0034] To keep the light conductor 26 permanently shielded from the vehicle interior or the underside of the roller blind assembly 14 ′, the light conductor 26 can be moved in the longitudinal direction of the roller blind into the channels 24B of the guide rails 22A and 22 . During this movement, the light conductor 26 can enter a rear-end guide 38 formed in the vehicle roof 10 . The roller blind 16 thus permanently forms a sunshade for the light conductor 26 , so that the sunshade is not visible to the passengers. This means that the passengers are not dazzled by the light emitted by the light conductor 26 .

[0035] To drive the flexible light conductors 26, they are each connected to the roller blind 16 extension supports 18 via coupling devices 36. Consequently, when the extension supports 18 are actuated, the light conductors 26 are displaced directly in the longitudinal direction of the roof in the channels 24 of the guide rails 22A and 22B, so that the light conductors 26 are arranged in the region of the roof section 12 only in the area that is also covered by the roller blind 16. The area of ​​the roof section 12 exposed by the roller blind 16 is not illuminated by the light conductors 26, whose rearward regions lie outside the guide rails 22A and 22B and are accommodated in a storage space formed by the guide devices 38. The LED assembly 28, whose light can be coupled into the light conductor 26, is displaced along with the light conductor 26.
