Abstract
Description
[0001] The invention relates to a sun visor for a motor vehicle, comprising an L-shaped axle, a long leg for supporting a sun visor body of the sun visor, and a short leg. The short leg is received in a through-opening formed in a bearing block of the sun visor. The sun visor comprises a support element having a portion near the axle and a support portion. The portion near the axle is spaced from a free end of the short leg. Furthermore, the invention relates to a motor vehicle having such a sun visor.
[0002] Accordingly, such an L-shaped axle can be used to support a sun visor body in a motor vehicle, with the short leg of the L-shaped axle being inserted into the through-opening of the bearing block and secured to the bearing block. To ensure secure mounting of the short leg in the bearing block, provision can be made for a comparatively long through-opening and, accordingly, a comparatively thick bearing block. This is because the short leg then provides a comparatively long lever arm, which provides appropriate support, for example, in cases where the long leg of the L-shaped axle is pulled downwards by a passenger of the motor vehicle.
[0003] However, the resulting high overall height of the bearing block, which has the passage opening, is disadvantageous if the aim is to reduce or keep the overall height of the motor vehicle low.
[0004] US 2,832,558 A describes a sun visor with a housing in which a horizontal slot with an arcuate shape is formed. A vertical portion of a curved rod of the sun visor is positioned in a vertical bore, the bore intersecting the slot. A pin extends laterally from the vertical portion of the rod and can engage one of two notches formed in the slot. A coil spring is positioned at the top of the bore and presses the pin into one of the notches.
[0005] DE 39 10 811 A1 describes a sun visor for motor vehicles with an axle having a portion located outside the visor body. The portion of the axle located outside the visor body is covered with a plastic casing, except for an end section that penetrates a bracket of a bearing block. Where it ends, the casing forms a flat bearing surface that rests against a corresponding bearing surface of the bracket.
[0006] Such a mounting of the sun visor is accompanied by a disadvantageous stiffness, for example when the visor body is to be pivoted towards a side window of the vehicle.
[0007] Another possibility for storing a sun visor in a motor vehicle is shown in US 4 525 008 A.
[0008] The object of the present invention is to provide a sun visor of the type mentioned at the outset, which provides improved support, and to provide a motor vehicle with at least one such sun visor.
[0009] This object is achieved by a sun visor having the features of patent claim 1 and by a motor vehicle having the features of patent claim 8. Advantageous embodiments with expedient further developments of the invention are specified in the dependent patent claims and in the following description.
[0010] The sun visor according to the invention for a motor vehicle comprises an L-shaped axle having a long leg for holding a sun visor body of the sun visor. Furthermore, the L-shaped axle has a short leg, wherein the short leg is received in a through-opening. The through-opening is formed in a bearing block of the sun visor. A support element of the sun visor has a partial region near the axle and a support region. The partial region near the axle is spaced from a free end of the short leg. The support region is received in a guide groove of the sun visor, wherein the support region is movable along the guide groove when the sun visor body is pivoted about a pivot axis provided by the short leg.
[0011] In principle, the support area can provide support when the long leg is subjected to a load acting in a predetermined direction, even if the support area comes into contact with a bearing area that is not designed as a groove. When the sun visor is mounted in the vehicle, for example, applying a downward load to the long leg can cause the support area to push upward, thus supporting itself against the bearing area or bearing.
[0012] However, due to the mounting or accommodation of the support area in the guide groove, improved support is achieved. This is because the guide groove can absorb loads that occur, for example, when pressure or tension is exerted on the long leg of the L-shaped axle, for example, when the long leg is pushed upwards or pulled downwards when the sun visor is mounted in the vehicle. The sun visor is thus advantageously improved, particularly with regard to support under loads acting in different directions.
[0013] While upward compressive loads are typically less common than downward tensile loads during actual use of the sun visor in a vehicle, the grooved design of the bearing area is advantageous in achieving particularly versatile load absorption.
[0014] Furthermore, the spacing of the section of the support element closest to the axis from the free end of the short leg means that the support area of the support element is also spaced away from the short leg. The support element therefore advantageously provides additional support for forces that occur when the long leg is loaded. This applies in particular to loads transverse to a plane spanned by the pivoting movement of the long leg when the sun visor body is pivoted about the pivot axis. This is because with such loads, the short leg alone no longer needs to support the entire load. Such a load can occur, for example, due to a passenger of the vehicle pulling the long leg of the L-shaped axis downwards when the sun visor is mounted in the vehicle.
[0015] The support element, designed like a cantilever, ensures a more extensive distribution of the forces applied during support. This, in turn, means that the length of the passage opening in the direction of the pivot axis can be comparatively short. Accordingly, the bearing block containing the passage opening can be designed to be comparatively flat. This is advantageous.
[0016] Reducing the overall height of the bearing block in the direction of the pivot axis allows the long leg of the L-shaped axis to be positioned relatively close to the inside of a windshield of the motor vehicle. This, in turn, allows the overall height of the motor vehicle including the windshield to be reduced. Accordingly, a flat or low design of the motor vehicle can be realized, which is particularly advantageously associated with low aerodynamic drag.
[0017] The provision of the guide groove also advantageously ensures that the path of movement when pivoting the sun visor body or the long leg about the pivot axis provided by the short leg is very precisely defined. This advantageously makes it particularly easy and convenient for a passenger to fold the sun visor body away from the windshield of the motor vehicle toward a side window of the motor vehicle when the sun visor is installed in the motor vehicle.
[0018] With respect to the direction of extension of the pivot axis, the free end of the short leg can be at a different height than the support region of the support element. Furthermore, the near-axis portion of the support element is preferably spaced from the free end of the short leg in the direction of the pivot axis provided by the short leg. This promotes a favorable distribution of the support forces.
[0019] In the sun visor according to the invention, a spring element of the sun visor is supported on the bearing block, wherein the short leg is movable along the pivot axis against a preload force of the spring element from an initial position to an overload position. The movement of the short leg from the initial position to the overload position can be effected by applying an abusive force to the long leg of the L-shaped axis. In this way, it can be achieved that even the application of the abusive force to the long leg of the L-shaped axis does not lead to the destruction of components of the sun visor. Rather, when the abusive force is applied, the short leg is first moved from the initial position to the overload position, whereby the short leg is displaced along the pivot axis. Accordingly, unwanted damage to components of the sun visor can be largely avoided.
[0020] It is also advantageous that even a comparatively slight movement of the short leg along the pivot axis from the starting position to the overload position is accompanied by a comparatively large travel path at a free end of the long leg of the L-shaped axis. Accordingly, even such a comparatively long travel path of the free end of the long leg of the L-shaped axis, which is associated with the application of the abusive force, advantageously does not lead to damage to components of the sun visor.
[0021] In addition, the movement of the short leg along the pivot axis against the preload force of the spring element from the starting position to the overload position is perceptible to the occupant of the motor vehicle, who applies the abusive force to the long leg of the L-shaped axis, for example by pulling the long leg or the sun visor body arranged on the long leg downwards.
[0022] Accordingly, the occupant is alerted by haptic feedback that they are applying the abusive force to the long leg of the L-shaped axle. Consequently, the occupant can abort the application of force before damage to the sun visor components occurs. This is advantageous.
[0023] In the sun visor according to the invention, the spring element is designed as a disc spring, whereby a sudden deformation of the disc spring from its initial shape to an overload shape can be effected by applying the abusive force to the long leg of the L-shaped axle. Advantageously, the sudden deformation of the disc spring from its initial shape to the overload shape is accompanied by acoustic and haptic feedback for the occupant of the motor vehicle, who applies the abusive force to the long leg of the L-shaped axle. This provides the occupant with a clearly perceptible indication that they are not handling the sun visor as intended, but are applying the abusive force to the long leg of the L-shaped axle.
[0024] Accordingly, the occupant is effectively alerted to the fact that an unintended load is being applied to the L-shaped axle. This allows the occupant to stop or abort the application of the abusive force.
[0025] This is advantageously accompanied by the fact that the disc spring returns from the overload position to its original shape. This again provides or releases the additional travel associated with moving the short leg from the original position to the overload position. Consequently, damage to the sun visor can be largely avoided.
[0026] By issuing acoustic and / or haptic feedback as a result of an overload or when applying the misuse force, it is possible in particular to prevent destruction of the sun visor in the form of breaking off the L-shaped axis or damage to the bearing block or the like.
[0027] Furthermore, damage to a component of the motor vehicle on which the sun visor is arranged or held can be advantageously avoided. This is particularly advantageous when the sun visor is mounted directly on the windshield of the motor vehicle. By preventing damage to the windshield, the associated costs and effort of repair can be advantageously avoided.
[0028] The same applies, however, if the sun visor is attached to a body shell of the vehicle, such as a sheet metal or similar. In this case, too, it is advantageous to prevent damage to such a component.
[0029] Preferably, the guide groove has a plurality of groove sections, wherein the respective groove sections provide different resistances to movement of the support area along the respective groove section. This makes it very easy to communicate to the occupant of the motor vehicle pivoting the sun visor body about the pivot axis which pivot position the sun visor body is in at any given time. This is advantageous for easy operation when pivoting the sun visor body about the pivot axis provided by the short leg.
[0030] For example, at least one groove section can ensure that, shortly before the sun visor body reaches an end position in which the sun visor body is pivoted toward a side window of the motor vehicle, the groove section provides or applies particularly strong resistance to the movement of the support area along this groove section. This makes it easy to signal to the occupant of the motor vehicle or the user of the sun visor that the sun visor body will soon reach this end position. This is advantageous, in particular, to prevent the occupant from attempting to pivot the sun visor body beyond the end position.
[0031] It is particularly simple and inexpensive if the guide groove is formed in one piece with a base body of the bearing block, whereby the base body of the bearing block has the passage opening.
[0032] Preferably, the guide groove has at least one locking element, which predetermines at least one pivoting position for pivoting the sun visor body about the pivot axis. This makes it very easy to signal to the occupant of the motor vehicle that the sun visor body has reached the pivoting position when pivoting the sun visor body into the at least one pivoting position. Furthermore, predetermined pivoting positions of the sun visor body can be predetermined very easily and with little effort. This is advantageous for particularly easy handling of the sun visor by the occupant of the motor vehicle.
[0033] Preferably, the support element is formed integrally with the L-shaped axle. The portion of the support element near the axle is designed as a molded-on area, where the L-shaped axle transitions into the support element. This allows for particularly simple and low-cost provision of the support element. In particular, the effort required to connect a portion of the support element near the axle, designed as a fastening area, to the base body of the L-shaped axle is eliminated.
[0034] This is especially true if the L-shaped axle is manufactured using an injection molding process. This makes it particularly easy to form the support element in one piece with the base body of the L-shaped axle by overmolding the support element. This also ensures a particularly robust mounting of the support element on the base body of the L-shaped axle.
[0035] The support area can be located farther from a free end of the long leg of the L-shaped axle than the short leg. This makes it very easy to achieve a good distribution or split of the load supported by the support element and the short leg.
[0036] Alternatively, the support area can be closer to the free end of the long leg of the L-shaped axle than the short leg. This is advantageous for a compact design of the sun visor.
[0037] Preferably, an end section of the support area provides a pivot point for a rotational movement of the L-shaped axle. The rotational movement can be effected by applying an abusive force to the long leg of the L-shaped axle. Such a design allows for particularly favorable leverage ratios, which are conducive to good absorption of the abusive force.
[0038] Preferably, the bearing block is held on a holding part of the sun visor, wherein the holding part has a contact area. The contact area is designed to secure the holding part to an inner side of a windshield of the motor vehicle. Particularly in a configuration such as this, in which the sun visor is secured directly to the inner side of the windshield of the motor vehicle via the holding part when the sun visor is installed in the motor vehicle, the low overall height of the bearing block achievable in this case is advantageous. This is because this is accompanied by a particularly small distance between the long leg of the L-shaped axis and the inner side of the windshield of the motor vehicle.
[0039] Arranging the long leg of the L-shaped axis as close as possible to the inside of the windshield advantageously makes it possible to reduce the overall height of the entire motor vehicle. In particular, it can be provided that, when the sun visor is folded down, a certain distance in the vertical direction of the motor vehicle must be maintained between a lower edge of the sun visor and a lower edge of the windshield. If this requirement can be met, arranging the long leg of the L-shaped axis closer to the inside of the windshield allows for an upper edge of the windshield to be arranged lower in the vertical direction of the motor vehicle, or for the windshield to be aligned flatter or at a greater incline. Both are advantageous for achieving a comparatively low or flat shape for the motor vehicle having the windshield.
[0040] The contact area can be designed, in particular, for a material-to-material fit to the inside of the windshield of the motor vehicle. Accordingly, the contact area can, for example, be glued to the inside of the windshield to secure the sun visor in the motor vehicle. This is advantageous with regard to particularly simple and low-effort installation of the sun visor.
[0041] The motor vehicle according to the invention has at least one sun visor according to the invention. Accordingly, the motor vehicle comprises the at least one sun visor, which provides improved support.
[0042] The advantages and preferred embodiments described for the sun visor according to the invention also apply to the motor vehicle according to the invention and vice versa.
[0043] The invention therefore also includes further developments of the motor vehicle according to the invention that have features already described in connection with the further developments of the sun visor according to the invention. For this reason, the corresponding further developments of the motor vehicle according to the invention are not described again here.
[0044] The motor vehicle according to the invention is preferably designed as a motor vehicle, in particular as a passenger car or truck, or as a passenger bus.
[0045] The invention also encompasses combinations of the features of the described embodiments. The invention therefore also encompasses implementations that each comprise a combination of the features of several of the described embodiments, unless the embodiments are described as mutually exclusive.
[0046] Exemplary embodiments of the invention are described below. Shown are: Fig. 1 shows a schematic exploded view of components of a sun visor for a motor vehicle; Fig. 2 excerpts from some of the Fig. 1 components shown in assembled state; Fig. 3 in a perspective view a bearing block of the sun visor according to Fig. 1 and a section of an L-shaped axle which is held on the bearing block, wherein a support element of the sun visor designed as an arm has a support area which is received in a guide groove of the bearing block; Fig. 4 a variant of the sun visor, in which the support element is designed as a cantilever which is arranged between a short leg of the L-shaped axis and a free end of a long leg of the L-shaped axis; and Fig. 5 schematically shows a motor vehicle with a windscreen on the inside of which the sun visor can be attached.
[0047] The exemplary embodiments explained below are preferred embodiments of the invention. In the exemplary embodiments, the described components of the embodiments each represent individual features of the invention that can be considered independently of one another, each of which also develops the invention independently of one another. Therefore, the disclosure is intended to encompass combinations of the features of the embodiments other than those shown. Furthermore, the described embodiments can also be supplemented by further features of the invention already described.
[0048] In the figures, the same reference symbols designate elements with the same function.
[0049] In Fig. 1 schematically and partially shows components of a sun visor 10 which is used in a motor vehicle 12 (compare Fig. 5) or can be installed in the motor vehicle 12. The sun visor 10 comprises an L-shaped axle 14 with a first, long leg 16. The long leg 16 is provided for holding a sun visor body 18 of the sun visor 10. The sun visor body 18 is in Fig. 1 is shown only schematically and in sections. Accordingly, Fig. 1 in particular a shape or a form as well as a size of the sun visor body 18 are not shown realistically.
[0050] If the sun visor body 18 is arranged on the long leg 16 of the L-shaped axis 14 in a manner not shown in detail here, the sun visor body 18 can be folded down or up about the long leg 16. In addition, it is possible to pivot the sun visor body 18 together with the long leg 16 about a pivot axis 20, which is provided by a second, short leg 22 of the L-shaped axis 14 (see Fig. 3).
[0051] From a summary of Fig. 1 with Fig. 3 it can be seen that the short leg 22 is received in a passage opening 24 which is formed in a bearing block 26 of the sun visor 10. According to Fig. 1 and Fig. 3, in the assembled state of the sun visor 10, the short leg 22 of the L-shaped axis 14 is received in the passage opening 24 in such a way that a free end 28 of the short leg 22 protrudes from the passage opening 24 in the direction of the pivot axis 20.
[0052] When designing according to Fig. 1 and Fig. 3, the short leg 22 has a ring element 30 in the region of the free end 28, with which according to Fig. 3 a spring element in the form of a disc spring 32 is attached. The disc spring 32 is according to Fig. 3 is also supported on an upper side of the bearing block 26, the free end 28 of the short leg 22 being guided towards this upper side through the passage opening 24 of the bearing block 26.
[0053] In particular from Fig. 3 shows that a base body 34 of the bearing block 26 has a comparatively low overall height in the vertical direction of the sun visor 10 and thus in the direction of the pivot axis 20 provided by the short leg 22. The passage opening 24 is formed in the base body 34 (see Fig. 1). The comparatively low overall height of the base body 34 and thus the comparatively short extension length of the passage opening 24 is achievable in this case because not only the portion of the short leg 22 accommodated in the passage opening 24 is intended to support the forces of misuse.
[0054] Such misuse forces can occur, for example, when the sun visor 10 is arranged in the motor vehicle 12, when an occupant of the motor vehicle 12 moves the long leg 16 or the sun visor body 18 downwards in a direction 36 which Fig. 1 is illustrated by a first arrow. Furthermore, the short leg 22 is intended to exert a supporting force to prevent mishandling of the sun visor 10 when the occupant of the motor vehicle 12 pushes the long leg 16 or the sun visor body 18 held on the long leg 16 upwards, as shown in Fig. 1 is illustrated by a second arrow 38.
[0055] If only the length of the passage opening 24 in the direction of the pivot axis 20 is to ensure the support of such misuse forces, a comparatively large length of the passage opening 24 and thus a correspondingly large thickness of the base body 34 is required. This entails that in the vertical direction z of the motor vehicle 12 (compare Fig. 5) and thus, essentially in the direction of the pivot axis 20, a comparatively large amount of installation space is required by the bearing block 26. This is disadvantageous. This is because the sun visor 10 plays a relevant role in a dimensional chain of the height or overall height of the motor vehicle 12. It must be ensured that when the sun visor body 18 is in front of a windscreen 40 of the motor vehicle 12 (cf. Fig. 5) is folded down, below a lower edge 43 of the sun visor body 18 (compare Fig. 1) there is always a certain amount of free space.
[0056] If the overall height of the bearing block 26 is reduced in the vertical direction of the motor vehicle 12 and accordingly essentially in the direction of the pivot axis 20, the sun visor body 18 can be positioned closer to an inner side 42 of the windscreen 40 (cf. Fig. 5). This, in turn, allows for a flatter design of the entire motor vehicle 12, i.e., a low overall height of the motor vehicle 12 in the direction of the vehicle's vertical axis, e.g. ...
[0057] Especially in the Fig. 1 shown embodiment of the sun visor 10, in which a direct attachment of the sun visor 10 to the inside 42 of the windscreen 40 (compare Fig. 5), a reduction in the overall height of the bearing block 26 can be directly translated into a reduction in the overall height of the motor vehicle 12. Accordingly, the Fig. 1 and Fig. 3, the comparatively flat design of the base body 34 of the bearing block 26 in the direction of the pivot axis 20 is advantageous.
[0058] In order to ensure good support against abuse forces, the sun visor 10 has Fig. 1 a support element 44 which is designed in the manner of a cantilever of the L-shaped axis 14. The support element 44 has a partial area 46 near the axis and a support area 48. According to Fig. 3, the support area 48 is further away from the pivot axis 20 than the near-axis portion 46 of the support element 44. Furthermore, in the present case, both in the Fig. 3 shown variant of the sun visor 10 as well as in Fig. In the variant of the sun visor 10 shown in Fig. 4, the partial area 46 near the axis is spaced in the direction of the pivot axis 20 from the free end 28 of the short leg 22 of the L-shaped axis 14.
[0059] The support area 48 of the support element 44 ensures that the entire load that must be supported when the misuse force is applied to the long leg 16 is no longer absorbed by the portion of the short leg 22 that is arranged or mounted in the passage opening 24. Rather, the support element 44, designed in the manner of a cantilever, provides additional support for misuse forces in an area of the bearing block 26 that is remote from the pivot axis 20. In particular, this additional support of the load across the width makes it possible to reduce the installation space required vertically by the bearing block 26.
[0060] Out of Fig. 1 and Fig. 3 further shows that the support area 48 is received in a guide groove 50, which in the present case is formed integrally with the base body 34 of the bearing block 26, which has the passage opening 24. The guide groove 50 is according to Fig. 1 and Fig. 3 is limited upwards or towards the free end 28 of the short leg 22 by a first wall 52 and downwards, i.e. in the direction of the pivot axis 20 towards the long leg 16 of the L-shaped axis 14, by a second wall 54.
[0061] Between these walls 52, 54, the support area 48 of the support element 44 is accommodated (compare Fig. 3). Accordingly, the guide groove 50 ensures good movement guidance when the long leg 16 or the sun visor body 18 (compare Fig. 1) is pivoted about the pivot axis 20. This is because when the sun visor body 18 pivots about the pivot axis 20 provided by the short leg 22, the support area 48 moves along the guide groove 50.
[0062] A torque to be applied for such a pivoting movement can be set or generated particularly easily depending on a pivot angle or a respective pivot position of the long leg 16 or the sun visor body 18 about the pivot axis 20. For example, by providing a corresponding nature of the guide groove 50 of the bearing block 26, it is possible to provide or generate a respective friction or a respective resistance to the movement of the support region 48 along a respective groove section of the guide groove 50 for each angular position or pivot position of the sun visor body 18.
[0063] In this way, it can be ensured in particular that shortly before the sun visor body 18 a side window (not shown) of the motor vehicle 12 (compare Fig. 5), a particularly high torque must be applied by an occupant of the motor vehicle 12. This advantageously signals to the occupant of the motor vehicle that the end of the movement is about to be reached, i.e., that the sun visor body 18 will soon reach its final position near the side window.
[0064] Furthermore, it is particularly easy to provide the guide groove 50 with molded-on portions or similar locking elements (not shown in detail here) in order to specifically predetermine specific locking or pivoting positions for the sun visor body 18 or the long leg 16 when pivoting about the pivot axis 20. This facilitates handling of the sun visor 10 for the occupant of the motor vehicle 12.
[0065] For example, locking thresholds and / or locking recesses can be formed in the guide groove 50 or along the guide groove 50 in order to specify corresponding locking positions for the support area 48 and thus certain pivoting positions for pivoting the sun visor body 18 or the long leg 16 about the pivot axis 20.
[0066] According to Fig. 1 and Fig. 3, the occupant of the motor vehicle 12 can also be given acoustic and haptic feedback when an overload occurs, i.e., when an excessive force is applied to the L-shaped axle 14. In this context, the disc spring 32 ensures, on the one hand, that the short leg 22 is preloaded relative to the bearing block 26. In Fig. 3, the disc spring 32 is shown in an initial shape in which the ring element 30 is spaced further from the upper side of the base body 34 than when the disc spring 32 is deformed and accordingly has an overload shape (not shown here).
[0067] When the disc spring 32 has the overload shape, the ring element 30 is closer to the top of the base body 34 than in Fig. 3. This sudden snapping or over-snapping of the disc spring 32 provides both haptic feedback and acoustic feedback in the form of a cracking noise. This alerts the occupant of the motor vehicle 12 that an undesirably high misuse force has been applied to the long leg 16 of the L-shaped axle 14.
[0068] Furthermore, the sudden deformation of the disc spring 32 from the initial shape into the overload shape ensures that the short leg 22 moves along the pivot axis 20 against the preload force of the disc spring 32 from the Fig. 3 shown starting position into an overload position (not shown). When the short leg 22 is moved into this overload position, the ring element 30 is closer to the top of the base body 34 than when the short leg 22 is in the position shown in Fig. 3 shown starting position.
[0069] This path released in the area of the pivot axis 20 allows for pivoting of the long leg 16 downwards in the direction 36, which Fig. 1 is illustrated by the first arrow, is advantageously also haptically perceptible by the occupant of the motor vehicle 12.
[0070] In addition, releasing an additional travel of just a few millimeters in the direction of the pivot axis 20 results in a free end of the long leg 16 being able to move several centimeters in the direction 36 indicated by the arrow. Accordingly, releasing the additional travel, which can be achieved by snapping the disc spring 32, effectively prevents failure of the L-shaped axis 14 in the event of an overload.
[0071] The acoustic and haptic feedback, which is achieved by the snapping or the sudden deformation of the disc spring 32 from its initial shape to its overload shape, can advantageously cause the occupant of the motor vehicle 12 to abort or terminate the application of the abusive force. If the abusive force is withdrawn by the occupant of the motor vehicle 12, the disc spring 32 springs back to its initial shape, which Fig. 3 is shown.
[0072] In Fig. 1 further shows a holding part 56 of the sun visor 10, which is designed to receive the bearing block 26. In particular, from a synopsis of Fig. 1 with Fig. 4 it can be seen that the holding part 56, which is designed in the manner of an adapter, has a contact area 58 which is used to fix the holding part 56 to the inside 42 of the windscreen 40 (cf. Fig. 5). In particular, the holding part 56 can be glued to the inner side 42 of the windshield 40 by applying an adhesive (not shown) to the contact area 58 and / or to the inner side 42 of the windshield 40.
[0073] The windscreen 40 of the motor vehicle 12 can be designed in particular in the manner of a panoramic window, which extends comparatively far into the area of a roof 60 of the motor vehicle 12 (cf. Fig. 5). In particular, if the windshield 40 of the motor vehicle 12 is designed as such a panoramic windshield, provision can be made for the sun visor 10 to be attached to the inside 42 of the windshield 40 by means of the holding part 56, for example by gluing the holding part 56 in the contact area 58 to the inside 42 of the windshield 40.
[0074] In particular, with such a design of the motor vehicle 12, the full height of a mounting of the sun visor 10 contributes to the vehicle height, i.e. to the extension of the motor vehicle 12 in the direction of the vehicle vertical axis z (compare Fig. 5). However, if the height of the mounting of the sun visor 10 is reduced, as explained here, the overall height or overall height of the motor vehicle 12 can also be reduced. This is advantageous.
[0075] In Fig. 1, a cover element 62 is also shown, by means of which components for supporting the sun visor 10 can be concealed. Accordingly, the cover element 62 conceals the holding part 56 and the bearing block 26 towards a passenger compartment 64 of the motor vehicle 12 (see Fig. 5) at least largely when the cover element 62 is arranged on the holding part 56 (compare Fig. 2).
[0076] The color of the cover element 62 can advantageously be freely selected. In particular, the color of the cover element 62 can correspond to the color of a paint finish on an outer skin of the motor vehicle 12.
[0077] The bearing block 26 can be fixed in the present case, for example, by locking it onto the holding part 56, wherein the bearing block 26 can in particular be accommodated in the holding part 56. A corresponding mounting of the bearing block 26 on the holding part 56 is shown in Fig. 4 shown schematically.
[0078] Furthermore, Fig. 4 shows a variant of the design of the boom or support element 44. Here, the support area 48 of the support element 44 is not as in Fig. 3, the support region 48 is further away from a free end of the long leg 16 of the L-shaped axle 14 than the short leg 22. Rather, the support region 48 is closer to the free end of the long leg 16 than the short leg 22.
[0079] Also in the Fig. In the variant of the boom or support element 44 shown in Figure 4, the support area 48 is received in the guide groove 50, which is preferably formed integrally with the base body 34 of the bearing block 26, which has the through-opening 24. However, here the guide groove 50 is not arranged on a side of the bearing block 26 facing away from the long leg 16. Rather, the guide groove 50 is also closer to the free end of the long leg 16 than to the short leg 22.
[0080] Furthermore, the Fig. 4, the disc spring 32 presses the short leg 22 with a preload force which is not in the direction of the pivot axis 20 as in Fig. 3 shown upwards, i.e. in the direction of the vehicle’s vertical axis z (compare Fig. 5). Rather, the preload force of the disc spring 32 in the variant of the sun visor 10 according to Fig. 4 ensures that when the disc spring 32 snaps over, the additional path upwards, i.e. towards the free end 28 of the short leg 22 of the L-shaped axis 14, is released.
[0081] However, even in the Fig. 4 shown variant of the sun visor 10, the sudden deformation of the disc spring 32 from the position shown in Fig. 4 shown initial shape into the overload shape (not shown) that the short leg 22 in the direction of the pivot axis 20 from the Fig. 4 shown starting position into an overload position (not shown). In this overload position, however, the free end 28 of the short leg 22 is further spaced from the top of the base body 34 of the bearing block 26 than in the position shown in Fig. 4 shown starting position of the short leg 22.
[0082] Through the Fig. The variant of the sun visor 10 shown in Figure 3 accordingly provides a one-sided lever, in which an end portion 66 of the support area 48 provides a pivot point for a rotational movement of the L-shaped axle 14. This rotational movement can be effected by applying the abusive force to the long leg 16 of the L-shaped axle 14.
[0083] In contrast, the variant of the sun visor 10 according to Fig. 4, a two-sided lever is formed. Here, too, the end portion 66 of the support area 48 provides a pivot point for the rotational movement of the L-shaped axle 14, wherein the rotational movement can be effected by applying the misuse force to the long leg 16 of the L-shaped axle 14.
[0084] It may be provided that the bearing block 26 is not (as in Fig. 1 to Fig. 4 by way of example) is designed for arrangement on the holding part 56, but instead for fixation to a (not shown) shell component of the motor vehicle 12, for example in the form of a shell. However, even in this case, the reduced height of the mounting of the sun visor 10 is advantageous. However, the corresponding advantages apply to a particular extent if (as explained here with reference to the figures) a direct attachment of the sun visor 10 to the inner side 42 of the windshield 40 of the motor vehicle 12 is provided.
[0085] In Fig. 4 also shows at least one line 68, through which electrical energy can be conducted, for example to supply a light source (not shown) of the sun visor 10 with power. For reasons of clarity, such lines 68 are shown in Fig. 3 not shown in detail.
[0086] Overall, the examples show how an advantageous mounting of the sun visor 10 can be provided, which is particularly advantageous with regard to the optimization of the installation space and with regard to acoustic and / or haptic feedback in the event of overload.
