Wind deflector and open roof construction for a vehicule fitted with such a wind deflector

Abstract: A wind deflector for use in an open roof construction of a vehicle having a roof opening (2) in its fixed roof (1) is adapted to be placed adjacent to the front side of the roof opening. The wind deflector (6) includes a connecting member (13) for a movable connection with the open roof construction so as to be adjustable between a downwardly pivoted, inoperative position and an upwardly pivoted, operative position. The connecting member (13) and/or the wind deflector (6) include snap means (21 - 27) via which the connecting member is attached to the wind deflector. Preferably, the connecting member connects the wind deflector to arms (9) which function to adjust the wind deflector upon movements of a closure element (4) of the open roof construction.

Description: The invention relates to a wind deflector according to the preamble of claim 1. A wind deflector of this type is known from DE 44 11 386 Cl. The connecting member is inserted into a cavity of the wind deflector in a direction parallel to the plane of the wind deflector and is held in position by snap means acting between the connecting member and the wind deflector. . The object of the present invention is to provide a new wind deflector of the kind referred to in the introduction. In order to accomplish that objective, the wind deflector according to the invention includes the features of the characterising portion of claim 1. The snap means, which may be integrated in the connecting member and/or in the wind deflector, enable a very simple manner of attaching the connecting member to the wind deflector. The invention will be explained in more detail hereafter with reference to the drawings, which show an embodiment of the invention. Figs. 1 and 2 are longitudinal sectional views of a part of the embodiment of the open roof construction according to the invention, in two different positions thereof. Fig. 3 is a larger-scale, perspective bottom view of a part of the wind deflector of the open roof construction of Figs. 1 and 2, showing the connecting member in partially mounted condition. Fig. 4 is a view corresponding to Fig. 3, showing the connecting member in entirely mounted condition. Fig. 5 is a perspective view from above of the part of the wind deflector of Fig. 3, showing the connecting member in partially mounted condition. Figs. 1 and 2 show an embodiment of the open roof construction according to the invention, which is built into a fixed roof 1 of a motor vehicle, such as a passenger car, which is provided with an opening 2 for accommodating the open roof construction. Said open roof construction comprises a frame 3 or the like stationary part to be fixed to the vehicle for movably supporting a closure element 4. In the illustrated embodiment the open roof construction is a so-called sliding/tilt roof, which is provided (in this case) with a more or less rigid and preferably transparent panel 4 as the closure element, which is capable of selectively closing roof opening 2 or releasing it to a smaller or larger extent by pivoting upwards or sliding to the rear. To this end, panel 4 is laterally supported by operating mechanisms, of which only a front slide 5 on one side of the panel is shown in the drawing, which slide is movably accommodated in an associated guide rail, which may be mounted on frame 3, for example, or which forms part thereof, and which extends in the longitudinal direction on one side of the roof opening 2. In order to prevent the wind from entering the vehicle when driving with panel 4 in its rearwardly moved position, a wind deflector 6 is mounted on the front side of the roof opening 2, directly behind the front edge thereof. Said wind deflector can be moved between a downwardly pivoted, inoperative position under panel 4 (Fig. 1) and an upwardly pivoted, operative position in which the wind deflector 6 projects above fixed roof 1 (Fig. 2). Wind deflector 6 is hinged on pivoting arms 7, which can pivot about pivots 8 under the front part of fixed roof 1. Operating arms 9 for operating wind deflector 6 are mounted on both ends thereof, which operating arms have a substantial length and which extend rearwards in the path of a ramp 10 on front slide 5, so that the arms can be pushed down by ramp 10 when panel 4 is being closed in forward direction. Each operating arm 9 pivots about a pivot 11 and is loaded in upward direction by an associated torsion spring 12, which is mounted between wind deflector 6 and the respective operating arm 9, and which loads the wind deflector 6 relative to the two operating arms 9 towards the position as shown in Fig. 2. Since the pivoting arms 7 and the operating arms 9 pivot about fixed pivots, and wind deflector 6 is rigidly attached to pivoting arms 7, the point of engagement between operating arms 9 and wind deflector 6 must be movable. To this end, wind deflector 6 includes a connecting member 13 for each operating arm 9 on the underside, which connecting member is provided with a curved slot 14, in which a pin 15 can engage at the front end of operating arm 9. Preferably, double slots 14 and pins 15 are used for each connecting member 13, and to this end the front end of each operating arm 9 is forked, with two pins 15 extending towards each other, which pins engage in associated slots 14 on either side of connecting member 13. Movement of pins 15 in slots 14 allows pivoting arms 7 and operating arms 9 to pivot relative to each other, in spite of the fact that pivots 8 and 11 remain at a fixed location. Figs. 3 - 5 show the construction and the attachment of connecting member 13 to wind deflector 6 in more detail. As is shown in Figs. 3 - 6, wind deflector includes a plate-shaped part 16 including a downwardly extending front wall 17 at its front edge, which wall follows the shape of the edge of fixed roof 1. A through opening 18 is formed in plate-shaped part 16 at both ends of wind deflector 6, which opening is rectangular and which is sufficiently large to allow a projecting part 19 of connecting member 13 to pass therethrough. At its upper end connecting member 13 includes a stop plate 20, which lies flat on the upper side of plate-shaped part 16 of wind deflector 6 in the mounted position of connecting member 13, and which hardly disturbs the streamline of the wind deflector, if at all. A cover 21 is formed on stop plate 20, at the rear edge thereof, which cover is connected thereto via a film hinge 22, which film hinge is so formed that it will abut flat against the rear edge of plate-shaped part 16 of wind deflector 6 when cover 21 is folded about the plate-shaped part 16 and comes into contact with the underside of the plate-shaped part of wind deflector 6. The cover 21 of connecting member 13 fits, via an opening 23, round the projecting part 19 of connecting member 13, which includes snap edges 24, 25 at its front and rear sides, which snap edges mate with the associated edges 26, 27 of opening 23 in cover 20, in such a manner that cover 20 snaps firmly about connecting member 13, thus securing the connecting member 13 to the plate-shaped part 16 of wind deflector 6. A hole 28 is formed in the projecting part 19 of connecting member 13, in which hole a leg of torsion spring 12 fits. In this manner the connecting member 13 is used not only for mounting the torsion spring 12, but the leg of said torsion spring also functions as an additional locking member for connecting member 13, which prevents cover 21 from becoming detached from snap edges 24, 25 of the connecting member 13. A cam 29 locks torsion spring 12 laterally in hole 28. From the foregoing it will be apparent that the invention provides a connecting member for a wind deflector which is remarkable for its simple mounting and the absence of additional mounting elements. The invention is not limited to the above-described embodiment as shown in the drawing, which can be varied in several ways without departing from the scope of the invention. Thus the wind deflector can also be used for other types of open roof constructions, such as spoiler roofs, folding roofs,slatted roofs and the like. The invention can also be used with other types of connecting members. Furthermore the connecting member and the wind deflector could each comprise a part of mating snap means, or the wind deflector could be snapped round the connecting member.
