Roller blind for sliding roof assembly

The invention relates to a roller blind for a sliding roof system, which consists of a flexible material and has two guide members along to the longitudinal edges of the shade extending and are intended, in a intervene guide for the corresponding longitudinal edge.

Such a blind can below an opening in a vehicle roof be attached to the opening, depending on the desire of the vehicle occupant or more less cover. If the opening is to be released, the shade is on a winding shaft wound. From this it can be deducted, so that it covering the opening. In order for the blind, when it is in below the opening Vehicle roof is located, does not sag in the vehicle interior into it, are received the longitudinal edges of the roller blind in a guide so that it transversely to Shifting direction can be held taut. Usually, the angled longitudinal edges of the shade and in guide grooves of a guide rail introduced. In this way, the desired tension can in the transverse direction be applied. The disadvantage here is that due to the angled Longitudinal edges a greater height is required. This reduces the Headroom in the vehicle interior. In addition, the transition section must the winding shaft until the entry into the guide of a veneer be covered, which means that is the delusion wider.

The object of the invention is to provide a blind which with taken little effort and a small footprint in a guide can be, so that it can be held taut in the transverse direction.

To achieve this object the invention provides that the Guide element a flat strip is provided at the corresponding longitudinal edge is secured so that it can be wound together with the roller blind. The Invention no longer relies on the fundamental consideration that Rollo side to angle in order to introduce it into a guide to make it taut can be gejhalten, but along the longitudinal edges of the shade as the flat strips running guide elements apply substantially straight, ie without having to be bent, in a the can run in respective longitudinal edge associated guide. The Guide elements are received in the guide that the desired Bias voltage can be obtained in the transverse direction.

According to a preferred embodiment of the invention it is provided that the guide element has a first cross-sectional shape in the initial state, which serves to receive the guide element in the guide, and in a second cross-sectional shape can be accommodated, which allows the roller blind wind. This embodiment is based on the basic idea, a to use change in shape of the guide element that the recorded guide element on the one hand suitable in the associated guide can be, but on the other hand flat on a winding shaft, together with the Roller blind can be wound up. Particularly suitable for this is a curved Cross-sectional shape of the guide element. If the guide member is curved is, it has a comparatively large height, which in for secure anchoring Inside the corresponding guide can be used. If that Guiding element, however, is flattened, it has a comparatively low Height which essentially corresponds to the material thickness. in this state wound, the guide member save space along with the blind will.

According to a further embodiment of the invention may be provided, that the guide element as a flat strip having a rectangular cross-section is executed. This can, in particular if it only partially with the Rollo is connected, also providing a secure anchorage in the guide be used.

Advantageous embodiments of the invention result from the Subclaims.

The invention is described with reference to a preferred embodiment described, illustrated in the accompanying drawings.

In Figure 1, a vehicle roof to see 5, which with an opening 7 is provided. The opening 7 is a cover 9 of a sliding roof system assigned. The lid 9 is movable between a closed position in which it closes the Öffnung- 7, and shown in Figure 1, open position be adjusted. is below the cover 9, and also below the opening 7 a roller blind 10 is disposed. The roller blind 10 can, based on the vehicle, according to be shifted front and rear. When the shade 10 is completely backwards is pushed, the opening 7 is completely released. Fresh air and Sunlight then have free access to the vehicle interior. If the blind 10 is fully pushed forward, the opening 7 is covered by the roller blind. Fresh air and sunlight can thus only to a limited extent in the Vehicle interior access.

The shade 10 is made of a flexible material such as fabric or a plastic film. At its front edge, a hoop 12 is provided to which a vehicle occupant can attack to the blind to forward or backward move. Side along the opening 7 extend two guides 14, in which the two longitudinal edges of the roller blind, that is, in the vehicle longitudinal direction considered the right and the left edge of the shade 10, are added. in the Region of the rear end of the opening 7 is located a winding axis 16, on of the roller blind 10 can be wound up. The winding shaft 16 is usually acted upon by a spring so that the roller blind 10 automatically on the is winding axis 16 is taken when the bow 12 to the rear is moved.

Along the longitudinal edges of the shade 10, so the guides 14 in the assigned area, each shade is provided with a guide element 18, which consists in the embodiment of Figure 3 as a thin metal strip is spring sheet formed. The guide element 18 has in its Initial state, ie when no external forces acting on it, which in Figure 3 visible, curved cross-sectional shape. The blind 10 is the Guide member 18 only on the outer half of the guide element 18 with connected this, so the outer edge to about the apex the guide element 18. This area is shown in Figure 3 by the reference numeral 20 referred to. The roller blind 10 can with the guide element 18 in particular be glued.

The guide 14 has in section a generally rectangular cross section, in the interior of which the guide member 18 together with the to him mounted edge portion of the shade 10 is fixed. At the center of the vehicle directed side, the guide has a leg 22 which between the blind 10 and directed towards the center of the vehicle portion of the guide member 18 engages, so in the area in which the shade 10 is not with the is glued guide member 18th The guide element 18 can be characterized supported below the leg to the roller blind 10 transversely excited to hold.

10 to wind up the roller blind on the winding axis 16, the Guide member 18 from the first cross-sectional shape shown in Figure 3 in a brought second cross-sectional shape. This is shown in Figure 4 (see the Arrow P designated transition area). After leaving the guide 14 and when wound on the winding shaft 16, the guide element 18 is flat compressed so that it has a rectangular cross section whose height the material thickness of the guide element 18 corresponds. in this state the blind 10 wound save space with the guide elements 18 will.

In addition to the curvature in the transverse direction, the guide element 18 also be curved in the longitudinal direction so that it rolls up automatically. To this Way possible to dispense with the usual wind-up on the winding shaft 16 will. At the same time is achieved a constant tension. Another effect is an increase in the displacement force, so that it is self-locking receives. Thus a manually operated roller blind remains in any intermediate position are without an additional blind brake is necessary.

In figure 5, an alternative embodiment is shown. For the first of the Embodiment known components here are the same numbers used, and reference is made to the above explanations.

The difference from the embodiment shown in Figures 3 and 4 is that the guide member shown in Figure 5 18 an innately flat, rectangular cross-section. As for inclusion in the guide 14 in the embodiment of Figures 3 and 4, the shade 10 with only one Half of the guide element 18 is connected, so that the other half behind the Leg 22 may be added.

When the shade 10 is wound on the winding axis 16, the slightly rotated edge portion of the shade, so that the guide member 18 flat abuts against the blind 10th In this state, it is then, together with the roller blind 10 is wound on the winding axis sixteenth
