Description

Wind screen for an openable roof section of a motor vehicle

Technical Field

The invention relates to a wind deflector for an openable roof cutout of a motor vehicle, comprising: a wind deflector clip at which a pliable wind deflector structure is retained and which has at least one lateral wind deflector arm; a guide assembly, by means of which the wind deflector clip can be moved, in the state of being mounted on the roof side, in the vertical direction and in the longitudinal direction of the roof section relative to the latter between a folded rest position and an erected functional position; the guide assembly has a curved guide track along which a guide element associated with the wind deflector arm is guided in a linearly forced manner in the vertical direction and in the longitudinal direction.

Background

Such a wind deflector is known from DE 10 2015 218 200 B3 and is arranged in the assembled state on the front side of a roof cutout of a motor vehicle, which can be closed by a movable roof. Known wind-shielding devices have wind-shielding clips, at which a flexible wind-shielding structure is held. The wind deflector clips extend in the transverse direction of the roof cross section over the entire width thereof and are each provided with a wind deflector arm at the opposite end face ends. The wind deflector clip is movable relative to the roof trim section between a folded rest position and an erected functional position. For this purpose, the wind deflector arms are each assigned a guide assembly with a curved runner track along which the runner elements assigned to the respective wind deflector arm are guided in a linearly forced manner in the vertical direction and in the longitudinal direction.

Disclosure of Invention

The object of the present invention is to provide a wind deflector device of the type mentioned in the opening paragraph, which allows a reliable displacement of the wind deflector clip between the rest position and the functional position.

This object is achieved by: the slide element is associated with a locking element which engages behind the slide rail and by means of which the slide element is locked when it is guided along the slide rail in a forced manner in the transverse direction of the roof cutout section. By means of the solution according to the invention, an undesired detachment of the chute element from the chute track is counteracted, which in turn counteracts a functional impairment of the wind-shielding device. Such a detachment of the gate element can be caused by external factors, for example wind loads acting on the wind deflector. Such wind loads can lead to undesired deformations of the wind deflector clip and in particular to undesired movements of the at least one wind deflector arm in the transverse direction of the roof cutout. Due to this displacement in the transverse direction, the chute element can be pulled out of the chute track and the function of the wind shield can be impaired. The solution according to the invention counteracts this and thus ensures a reliable movement of the wind deflector clip between the rest position and the functional position. The locking element brings about a form-locking between the at least one wind deflector arm and the guide arrangement, which locking is effective in the transverse direction. For this purpose, the locking element can be arranged at the gate element or can be provided separately from the gate element. The link element and the locking element can be arranged on the wind deflector arm and the link rail can be arranged on a functional component, which is fixed to the vehicle in the state of being mounted on the roof side, or vice versa. The wind deflector clip preferably extends in the assembled state in the transverse direction of the roof cutout section and/or in the transverse direction of the vehicle. Preferably, the at least one wind deflector arm is angled with respect to the transverse direction. At least one wind deflector arm is used to support the wind deflector clip. The wind deflector clip is used to transition the flexible wind deflector structure between a stored stowage position and an open wind deflecting position. The stowage position of the wind deflector corresponds to the rest position of the wind deflector clamp. The wind shielding position corresponds to the function position. Preferably, the wind deflector clip is supported by two transverse wind deflector arms, wherein each of the wind deflector arms is guided forcibly by means of a separate guide assembly. If two wind deflector arms are provided, these wind deflector arms and the corresponding guide assemblies are mirror images of one another, but are otherwise identically designed. The solution according to the invention is suitable in a particularly advantageous manner for use at the front of a roof section of a passenger vehicle, wherein the roof section is closed by means of an openable roof panel which is movable along the roof section between a closed position and an open position. The roof can be embodied as a sliding roof or as a sliding roof. The location information, position information and/or direction information used in this description refer to a state of the wind deflector on the roof side, in which the wind deflector clamp is arranged in the region of the roof cutout section that is forward in the longitudinal direction.

In one embodiment of the invention, a locking element in the form of a mushroom head is attached to the runner element at the end face end and forms a mushroom head locking device together with the runner rail. The mushroom head forms a widening or a thickening of the runner element on the end face side, so that the runner element is fixed directly in the transverse direction in the region of the runner rail at the guide arrangement. The mushroom head can be integrally molded to the gate element. Alternatively, the mushroom head can be produced separately from the chute element and thereafter be engaged with this chute element. The gate element can be designed in particular in the form of a pin, cam, sliding block or the like. It has been found that a particularly secure fixing of the runner element and thus a particularly secure displacement of the wind deflector clip can be achieved by means of the mushroom head locking device.

In a further embodiment of the invention, the mushroom head has a rectangular basic shape — in the viewing direction oriented in the transverse direction. Compared to a circular basic shape with the same diameter, an increased contact surface of the mushroom head can be achieved by this configuration of the invention. The bearing surface serves to support the mushroom head in a transverse direction, for example at a correspondingly oriented transverse support surface of the guide assembly. The rectangular basic shape ensures that the surface pressure is reduced when the mushroom head comes to bear against the transverse support surface. Due to the reduced surface pressure, the slidable mobility of the mushroom head at the lateral support surface is improved. From this, can avoid the spout component to block, and then can avoid damaging the mobility of deep bead clamp.

In a further embodiment of the invention, the gate track is designed in the form of a closed gate gap with a widened passage opening compared to the width of the gate gap in the other sections for the assembly and/or disassembly of the locking element. The passage opening extends in the transverse direction and has a diameter which is matched in size to the maximum diameter of the locking element and is larger than this maximum diameter. The passage opening can have any cross-sectional shape, preferably adapted to the contour of the locking element. The gate gap is closed at the end face end, so that the gate element cannot be disengaged from the gate gap in the longitudinal and vertical directions when it is guided in a forced manner.

In a further embodiment of the invention, the passage opening is arranged at an end face end region of the gate gap, wherein the locking element can be moved into the region of the passage opening by means of a movement of the wind deflector clip into the installation position, which exceeds the rest position or the functional position. By means of this configuration of the invention: this locking is unintentionally released when the wind deflector clip is moved between the functional position and the rest position. This is ensured by the arrangement of the passage opening on the end face side, wherein the locking element reaches this end face end region only when the wind deflector clip is folded more flat for assembly and/or disassembly relative to the rest position or is raised more steeply relative to the functional position.

In a further embodiment of the invention, the locking element is supported in a sliding-movable manner on a transverse support surface of the guide assembly oriented in the transverse direction. By the support in the transverse direction, the wind deflector arm can be better guided along the chute track.

In a further embodiment of the invention, the guide arrangement has at least one guide web, which rises in the transverse direction and runs parallel to the gate rail and at which the locking element is guided in the vertical direction and in the longitudinal direction. The guide webs serve for the positive guidance of the locking element parallel to the positive guidance of the gate element. In this way, the forced guidance of the wind deflector arm can be improved again, so that the wind deflector clamp can be moved particularly reliably.

In a further embodiment of the invention, the guide assembly has a support surface which extends at least in sections parallel to the gate track and on which the support section associated with the wind deflector arm is supported in a sliding manner. The support section serves for additional support of the wind deflector arm at the guide assembly. This ensures that the wind deflector clip is stable in the raised functional position with respect to forces acting on the wind deflector clip from above.

In a further embodiment of the invention, at least one functional component is provided, at which the slotted link track is formed, wherein the slotted link element and the locking element are formed at the wind deflector arm. If a transverse support face is provided, at which the locking element is supported in a manner that enables sliding movement in the transverse direction, this transverse support face is advantageously likewise arranged at the functional component. The functional component is arranged in a fixed manner in the region of the roof cutout in the mounted state on the roof side. If the wind deflector clip has two transverse wind deflector arms, it is advantageous if each of these wind deflector arms is assigned a functional component.

Detailed Description

According to fig. 1, a wind deflector 1 for an openable roof cutout section D of a motor vehicle is provided, the remainder of which is not shown in detail. According to fig. 1, the roof cutout D is schematically simplified and partially cut out by means of a dashed line there and can be opened and closed in a manner known in principle by means of a roof cover, not shown. The roof is part of a sliding roof system of a motor vehicle and can be moved in a manner known in principle between an open position, in which the roof section D is released in the vertical direction Z, and a closed position, in which the roof section D is covered in the vertical direction Z by means of the roof.

In the present case, the wind deflector 1 is shown in the ready-to-mount state on the roof side and is arranged in the front edge region of the roof cutout D in the longitudinal direction X. In this case, the wind deflector 1 serves to avoid strong ventilation noises or unpleasant ventilation phenomena in the interior of the motor vehicle in the open state of the roof cutout D.

The wind deflector 1 has a wind deflector clip 2, which in the present case extends longitudinally in the transverse direction Y of the roof cutout. The wind deflector clip 2 extends in the present case over almost the entire width of the roof cutout D. The flexible wind deflector 3 is held at the wind deflector clip 2 and can be moved between a stowed stowage position (Stauposition) and a tensioned wind deflecting position (fig. 1) in a manner which will be described in more detail. In the present case, the flexible wind deflector structure is designed in the form of a textile net 3 and is held at one end by the wind deflector clip 2 and at the other end by means of a vehicle-fixed connection to the roof side in a manner known in principle and not shown in detail.

In the present case, the wind deflector clip 2 has two transverse wind deflector arms 4 which are arranged at end regions which are opposite to one another in the transverse direction Y. In the present case, the wind deflector arm 4 is constructed integrally with the wind deflector clip 2 in the other part.

In order to move the flexible wind deflector 3 between the stowage position and the wind-deflecting position described, the wind deflector clip 2 can be moved relative to the roof section D between the folded rest position (fig. 3) and the erected functional position (fig. 1, 4) in the vertical direction Z and in the longitudinal direction X of the latter. In the upright functional position, the flexible wind deflector 3 is in the present case extended in a taut manner, as a result of which the oncoming wind occurring during the driving movement of the motor vehicle can be guided over the roof cutout D. In contrast, in the folded rest position, the flexible wind deflector 3 is stored compactly, which is not shown in detail in the figures.

In order to move the wind deflector clip 2 between the rest position and the functional position, a guide assembly 5 is assigned to each of the two wind deflector arms 4. In this case, the wind deflector arm 4 and the guide arrangement 5 are each configured in the present case mirror-symmetrically with respect to a vertically oriented middle longitudinal plane, not shown in detail, of the wind deflector 1 and are otherwise identical. To avoid repetition, only the guide assembly 5 on the left-hand side, with respect to the drawing plane of fig. 1, is discussed below. The disclosure in this connection applies in a corresponding manner to the guide assembly 5 on the right.

As can be seen in particular from the enlarged detail view of fig. 2, the guide assembly 5 has a curved guide track 6 along which a guide track element 7 associated with the wind deflector arm 4 is guided in a forced manner in the vertical direction Z and in the longitudinal direction X. In the present case, the curvature of the gate track 6 is virtually circular-arc-shaped, so that the wind deflector arm 4 can be moved relative to the roof cutout D when the gate element 7 is moved in a positively guided manner in the longitudinal direction X and at the same time in the vertical direction Z. In the present case, the link element 7 is a slide, not shown in detail, which is held in a sliding manner in the link track 6 and is integrally molded on the end face end side on the wind deflector arm 4.

In order to move the wind deflector clip 2 from the rest position (fig. 3) into the functional position (fig. 4), a spring unit, not shown in detail, is assigned to each of the two wind deflector arms 4, which spring unit exerts a permanent force load and/or a torque load on the respective wind deflector arm 4 in the direction of the upright functional position. As soon as the cover is moved from the closed position in the direction of its open position toward the opening of the roof cutout D, the wind deflector clip 2 is automatically forcibly raised into its raised functional position by the action of the spring unit. When the cover is moved from its open position into its closed position, it can exert a corresponding load on the wind deflector clip 2 against the spring unit, as a result of which this wind deflector clip is forcibly moved in the direction of its rest position, back and forth in the vertical direction Z and in the longitudinal direction X.

In the present case, the gate rail 6 is formed on a functional component 8 which, in the state of being mounted on the roof side, can be arranged on the side of the roof cutout D and is fixedly connected to a carrier of the sliding roof system in a manner not shown in detail. For this purpose, the functional component 8 has in the present case a fastening opening 9 for accommodating a fastening means. For example, the fastening means can be screws or the like, by means of which the functional component 8 can be connected with the carrier.

As can be further seen from fig. 2, the gate element 7 is assigned a locking element 10 of the counter-hook (hingreifen) gate rail 6, by means of which the gate element 7 is locked when it is guided along the gate rail 6 in the transverse direction Y. By this locking is avoided: the gate element 7 is disengaged from the gate rail 6, for example, as a result of wind loads or as a result of an undefined manual displacement of the wind deflector clip 2 (ausgreifen).

In the present case, a locking element in the form of a mushroom head 10 is attached directly to the gate element 7 on the end face end side. In this way, the mushroom head 10 forms a mushroom

head locking device

10, 6 together with the runner rail 6. The mushroom head 10 forms a widening or thickening of the gate element 7 on the end face end side and thus ensures a form-locking lock in the transverse direction Y. In the present case, the mushroom head 10 is constructed integrally with the link element 7 and thus with the wind deflector arm 4.

The gate track is formed as a closed gate gap 6, wherein "closed" means that the gate gap 6 is delimited at end

face end regions

11, 12, which are opposite one another in the guide direction, by corresponding wall sections, not shown in detail, of the functional component 8. In order to still be able to fit the mushroom head 10, the gate gap 6 has a passage opening 13. The passage opening 13 widens compared to the width of the slot gap 6 in the rest of the slot and is matched in size to the outer contour of the mushroom head 10. Thus, for fitting the wind deflector arm 4 at the functional component 8, the mushroom head 10 can be guided through the passage opening 13 from the inside outwards in the transverse direction Y and moved forward and upwards in the vertical and longitudinal directions Z, X. For the disassembly, the process is reversed accordingly.

In the present case, the passage opening 13 is arranged in the end face end region 12 at the rear in the longitudinal direction X. As can be seen from fig. 3 and 4, this end face region 12 is not reached when the wind deflector clip 2 is moved between the rest position and the functional position. In contrast, in the rest position, the mushroom head 10 is arranged together with the gate element 7 in the front end face end region 11 of the gate gap 6. In the functional position of the wind deflector clip 2, the mushroom head 10 is displaced together with the gate element 7 in the direction of the rear end face end region 12, but is nevertheless arranged at a distance from this rear end face end region. In order to assemble and/or disassemble the wind deflector arm 4, the wind deflector clip 2 must be moved into the position that can be seen according to fig. 5 in the present case. This position can also be referred to as the assembly position and overrides the functional position (fig. 4). Only in this assembly position can the mushroom head 10 be unlocked from the runner rail 6 in the manner described above.

In the present case, the locking element 10 is supported in a slidably movable manner at a

transverse support face

14, 15 oriented in the transverse direction Y, which in the present case has a first face section 14 and a second face section 15. The first surface section 14 is arranged above the gate gap 6, and the second surface section 15 is arranged below the gate gap 6. During the forced guidance of the gate element 7 along the gate gap 6, the mushroom head 10 slides with a sliding surface, not shown in detail, behind the drawing plane in fig. 2 along the transverse support surfaces 14, 15. However, such a sliding support is not absolutely necessary. In an embodiment, not shown, the mushroom head 10 can be spaced apart from the functional component 8 in the transverse direction Y and can only slide against a transverse support surface under the action of an external load.

In the viewing direction oriented in the transverse direction Y, the mushroom head 10 has in the present case a rectangular basic shape G. This design of the mushroom head 10 ensures that the surface pressure at the lateral support faces 14, 15 is reduced compared to a cylindrical basic shape with the same diameter. Correspondingly, the passage opening 13 is adapted to the basic shape G of the mushroom head 10 and therefore has a complementary rectangular inner contour.

In the present case, the lateral support surfaces 14, 15 are arranged in pocket-like recesses of the functional component 8 and are bordered in this respect by the encircling guide webs 16. The guide webs 16 project in the transverse direction Y from the transverse support surfaces 14, 15 and run parallel to the gate gap 6. The guide webs 16 serve to additionally guide the mushroom head 10 in the vertical and longitudinal direction Z, X.

As can be further seen, in particular, from fig. 3 to 5, the guide assembly 5 has a support surface 17 which extends at least in sections parallel to the gate track 6 and on which a support section 18 associated with the wind deflector arm 4 is supported in a slidably movable manner. The support section 18 is formed at a support cam 19, which is fastened to the wind deflector arm 4. In the configuration that can be seen from fig. 1, the supporting cam 19 is hidden from view. In the present case, the support surface 17 is arranged on the upper side of the functional component 8 in the vertical direction Z and is formed by an outer wall section of the functional component. By means of the additional slidably movable support between the support surface 17 and the support section 18, the wind deflector arm 4 is additionally supported on the functional component 8 during the forced guidance of the gate element 7 along the gate gap 6. By means of this additional support, the stability of the wind deflector clip 2 is increased and the guidance between the rest position and the functional position is improved.
