Definitions

• the invention relates to a wind deflector of a vehicle roof with the features of the preamble of claim 1 and a wind deflector with such a Windabweiserelement.
• Such a wind deflector is known in practice and is used in an apparent vehicle roof having a sliding lid member.
• the wind deflector is arranged in a bow-side edge region of a roof opening, which can optionally be closed by means of the cover element or at least partially released.
• the wind deflector comprises a blank made of a foldable, in particular reticulated material, which is tied to the roof at its lower edge via a lower edge strip and is tied at its upper edge to an extension bar via an upper edge strip, which is U-shaped and with its free legs, which each form a so-called extension arm, is pivotally mounted in the region of a respective roof-fixed guide rail or vehicle-fixed base.
• the Ausstellbügel is in dependence on the opening position of the lid member between a depressed rest position in which the
• Wind deflector is folded, and a flared operative position pivoted in which the Windabweiserelement is clamped and forms an inflow surface.
• the edge strips of the wind deflector element are made of plastic and are connected to the blank made of the foldable material by an injection molding process. Since the edge strips must have a certain rigidity for stable connection of the Windabweiserelements to the Ausstellbügel and the vehicle-fixed base, the plastic of the edge strips is designed to be stiff.
• the Windabweiserelement is based on a vertical vehicle longitudinal center plane on both sides in the each end formed curved and guided into the region of the opening arms of the Ausstellbügels.
• the blank of the foldable material must be inserted into the corresponding injection-molding tool during the production of the edge strips with correspondingly curved end regions.
• the injection mold is formed with a complex mold cavity, which is why a demolding is possible only by the use of multiple slides. This makes the mold expensive, which in turn is reflected in the cost of Windabweiserelements. Consequently, an adaptation of the injection mold to a changed exhibition height or a modified width of the Windabweiserelements consuming, time-consuming and therefore expensive.
• the invention has for its object to provide a Windabweiserelement the introductory genus, whose production is possible with a comparison with the prior art simplified executed injection mold. This object is achieved by the wind deflector element with the features of claim 1.

• At least one of the edge strips has a central portion, to each of which an end portion adjoins with respect to a vertical vehicle longitudinal center plane on both sides, whose bending resistance is lower than that of the central portion.
• At least one of the two edge strips is provided with reduced rigidity, ie greater flexibility than the middle section, in its end regions arranged on both sides, whereby it is possible to make the blank of the foldable material substantially flat Arrangement in a mold cavity of an injection mold to make the relevant edge strip.
• the edge strip can be bent after removal from the injection mold during assembly to the Ausstellbügel or the vehicle-fixed base in the end portions and are adapted to the desired course of the Windabweiserelements in the installation position.
• the injection mold used for the production of the respective edge strip can be produced at short notice with reduced effort. This also enables the shortening of delivery times for the wind deflector element.
• the end portions each have at least one bending zone, which is formed by a material taper of the plastic.
• a trained edge strip is in particular the first edge strip, which serves for connection to the Ausstellbügel. The material taper leads to an increase in the flexibility or reduction of the flexural rigidity in the corresponding area.
• the end portions are formed as two-component Spritzg cordabitese. This makes it possible to keep the cross section of the respective edge strip constant over its length, but to use a material or a soft component in the end sections which has a low flexural rigidity, and on the other hand to use a material which constitutes a hard component and plays a key role in the connection of the edge strip to the vehicle-fixed base or the Ausstellbügel.
• a material component of the two-component injection molding section is formed of a flexible thermoplastic elastomer and the other material Component, which has a supporting function, formed of a hard plastic, which has a greater flexural rigidity than the elastomer.
• the skirting with the end portions may have fixing lugs for connecting the edge strip or the Windabweiserelements to the vehicle-fixed base or the Ausstellbügel.
• the fixing lugs which are arranged within the end regions of the respective edge strip, are preferably formed at least in part from the hard plastic so that they can absorb the forces occurring in the installation position, which arise in particular by the wind load in the active position of the corresponding Ausstellbügels the wind deflector.
• the edge strip has an at least approximately L-shaped cross section with the end sections, one leg of the edge strip forming a diaphragm section which is formed in the end sections arranged on both sides from the thermoplastic elastomer.
• the diaphragm section which covers, for example, a channel of the vehicle-fixed base, can be used to prevent water and to optically conceal the vehicle
• the thermoplastic elastomer forms a first material layer and the hard plastic forms a second material layer.
• the hard plastic which forms the second layer of material, forms its "soul" over the entire extent of the respective edge strip
• the hard plastic is made of polypropylene with a glass fiber content of 30% by reducing the cross section of the hard plastic and Substitution of the corresponding profile components by the soft component or the elastomer, the edge strip in the end sections has a reduced flexural rigidity, so that the whole system is more flexible.At the same time, however, the cross-sectional profile and thus the area moment of inertia can remain constant.The risk of breaking the skirt in their Bending in the form of assembly is thereby reduced.
• the invention also relates to a wind deflector element with the features of claim 8.
• a skirt is formed as a two-component injection molded part having a material component made of a flexible thermoplastic elastomer and a material component of a hard plastic whose bending stiffness is greater than that of the elastomer.

• the wind deflector 18 serves to prevent the formation of any disturbing air currents and air turbulence in the vehicle interior when the roof opening 14 is open, that is to say when the cover element 16 is moved back.
• the wind deflector 18 comprises an at least approximately U-shaped Ausstellbügel 20, which has two Ausstellarme serving as legs 22A and 22B, which are connected to each other via a extending in the vehicle transverse direction leg 24.
• the Ausstellarme 22A and 22B are each pivotally mounted in the region of a vehicle longitudinally extending, forming a vehicle-fixed base guide rail for the lid member 16 and each biased for example by means of a Ausstellfeder in Ausstellraum.
• the Ausstellgrad the Ausstellarme 22 A and 22 B and thus the Ausstellbügels 20 is determined by the position of the cover member 16 in the vehicle longitudinal direction relative to the adjacent to the roof opening 14 fixed roof sections.
• the lid member 16 moves when closing the roof opening 14, starting from an open position from behind on the Ausstellarme 22A and 22B and pushes them against the force of the Ausstellfedern down, that means in a rest position.
• the opening arms 22A and 22B are released, so that the Ausstellbügel 20 can swing out by the action of the Ausstellfedern automatically in an operative position.
• the wind deflector 18 has a Windabweiserelement 26 which is clamped between the Ausstellbügel 20 and a vehicle-fixed base, which may be formed by a sunroof frame, which also includes the guide rails.
• the Windabweiserelement 26, which is shown in Figures 4 to 10 in isolation, comprises a blank 28 of a net-like foldable material which has parallel edges in a central portion and tapers in its relative to the vehicle longitudinal central plane disposed on both sides end portions.

• the upper edge strip 30 has a central portion M, which merges on both sides in an end portion E relative to the vertical roof longitudinal center plane.
• the end sections E have a reduced flexural rigidity relative to the middle section M. This is realized in that the end sections E, which is made of the same material as the middle section M, each have three bending zones 33, which are formed by a material taper of the plastic of the edge strip 30.
