Description

Technical Field

[0001] The invention relates to a screening device for the vehicle interior of a motor vehicle, comprising a supporting frame, on which a roller blind shaft is rotatably mounted, on which a flexible roller blind web is held in a roll-up and unrollable manner, and the supporting frame is provided with guide profile assemblies on opposite longitudinal sides for lateral guidance of the roller blind web, wherein opposite side edges of the roller blind web are provided with lateral guide strips, which are guided in the region of each guide profile assembly in such a way that in an at least partially extended functional position of the roller blind web, a tension force is exerted on the roller blind web transversely to the extension direction of the roller blind web. Background Art

[0002] DE 10 2017 217 429 A1 discloses a shielding device of this type for a glass roof area of ​​a passenger car. The known shielding device has a supporting frame which is mounted on a roof body section of the passenger car from the bottom. In the supporting frame, a roller blind web can be moved between a shielding position in which the glass roof area is shielded and a rest position in which the glass roof area is released. The roller blind web is held on a roller blind shaft which is rotatably supported in the supporting frame in a roll-up and unwindable manner. The roller blind web has a dimensionally stable extension profile at its front end region in the extension direction, which is movably guided in lateral guide rails of the supporting frame. The roller blind web is provided with lateral guide strips on its opposite side edges extending in the longitudinal direction, which are each guided in a corresponding lateral guide rail. This ensures, on the one hand, that in the shade position of the roller blind web, the side edges of the roller blind web and the lateral guides of the supporting frame overlap relative to one another, so that no visible gap remains between the roller blind web and the lateral guides. On the other hand, the lateral guide strips maintain the transverse tension of the roller blind web, so that the roller blind web is prevented from sagging in the shade position of the roller blind web. Summary of the invention

[0003] The object of the present invention is to provide a screening device of the type mentioned at the outset which achieves a permanently good quality impression during operation.

[0004] This object is achieved in that the bearing adjacent to the end of the roller blind shaft is provided on both sides with support guides for transferring the corresponding lateral guide strips into the channel section of the guide profile assembly, said support guides being positioned between the end bearing and the open end region of the channel section of the guide profile assembly. Adjacent to the bearing means that the support guides are arranged offset relative to the rotation bearing point of the roller blind shaft in the extension direction of the roller blind web. The solution according to the invention makes it possible to reliably transfer the lateral guide strips from the wound rest position into the corresponding guide profile assembly in each lateral edge region of the roller blind web, so that a constant transverse tension on the roller blind web can be achieved from the rest position of the roller blind web to the extended shielding position. In addition, the support guides allow the corresponding lateral guide strips to be reliably inserted into the guide profile assembly of the supporting frame fixed to the vehicle. The solution according to the invention is provided in a particularly advantageous manner for shielding the glass roof region of the vehicle interior of a passenger car. In the same way, the shielding device according to the invention can also be used for other window panes of a motor vehicle.

[0005] In the design of the invention, the supporting guide has a profile section which is provided for linearly movable guidance and for transversely supporting the lateral guide strip, thereby achieving precise guidance and centering of the lateral guide strip in the direction of the channel section of the guide profile assembly.

[0006] In another embodiment of the invention, the support guide is provided with an elastically flexible guide tab, which supports the roller blind web attached to the lateral guide strip transversely to the withdrawal direction under prestressing at the bottom during the winding or unwinding process. The roller blind web attached to the lateral guide strip is a partial area of ​​the flexible roller blind web, which either forms an edge area that is rolled around the corresponding lateral guide strip, or has a longitudinal seam, or transitions unchanged into the remaining area of ​​the roller blind web in the transverse direction and is therefore indistinguishable from the remaining area of ​​the roller blind web. The roller blind web is preferably made of a textile material, in particular a textile knitted fabric. The elastically flexible guide tab supports the roller blind web from below during the unwinding process or the winding process in the transition area between the roller blind web reel and the entry end side of the guide profile assembly, so as to support the oblique entry of the side edge of the roller blind web in the longitudinal direction. This prevents the corresponding lateral roller blind web from being damaged at the end edge of the support guide during the winding or unwinding process. This ensures a good quality impression even when the screening arrangement is in operation for a longer period of time. The guide tabs form a bridge extending approximately parallel to the course of the lateral guide strips, which supports from below the strip-shaped longitudinal sections of the roller blind web which are attached laterally to the lateral guide strips in the transverse direction.

[0007] In another embodiment of the present invention, the guide tab extends from the support guide along the extension direction of the roller blind web in the direction of the roller blind shaft. The guide tab protrudes freely from the support guide and preferably has a tongue-shaped curvature in the longitudinal direction, which causes an arc-shaped support of the roller blind web in the direction of the roller blind shaft.

[0008] In another embodiment of the invention, a bearing module is arranged on the opposite end sides of the roller blind shaft for supporting the roller blind shaft on the end sides, and the support guide is fixed to the bearing module. The support guide is arranged offset relative to the rotary bearing section of the bearing module of the roller blind shaft in the extension direction of the roller blind web. By fixing the support guide to the bearing module, a uniform handling of the bearing module, the roller blind shaft, the roller blind web and the support guide is ensured, which enables pre-assembly of the unit.

[0009] In another embodiment of the present invention, the support guide is configured as a plastic component. Preferably, the support guide is manufactured as an injection-molded component.

[0010] In another embodiment of the invention, the support guide and the bearing module have mutually complementary plug-in connection sections, by means of which the support guide can be fixed to the bearing module without tools, thereby ensuring a simple plug-in assembly of the support guide on the bearing module.

[0011] In another embodiment of the invention, the elastically flexible guide tab is integrally formed on the support guide. This ensures that the support guide can be manufactured as a plastic component in combination with the guide tab in a single-stage manufacturing process. Preferably, the guide tab is made of the same material as the support guide. As an alternative, the guide tab can be made of a plastic material that is more elastic than the support guide. In this case, the manufacturing can be carried out by coextrusion of different plastic materials.

[0012] In another embodiment of the invention, the guide tab is positioned laterally offset relative to a profile section of the support guide, which is provided for guiding the lateral guide strip. Thus, viewed in the longitudinal direction of the lateral guide strip, the guide tab extends laterally offset relative to the profile section of the support guide for the lateral guide strip. However, in this case, the guide tab can protrude further from the support guide in the longitudinal direction in the direction of the roller blind shaft than the profile section of the support guide for the lateral guide strip extends.

[0023] according to Figures 1 to 3The shielding device 1 is provided for shielding the glass roof area of ​​a passenger car. In the state of being mounted on the vehicle side, the shielding device 1 is mounted below the glass roof area on the vehicle interior space side. The shielding device 1 has supporting frames 2a to 2c, which carry the functional parts of the shielding device 1 described below and are fixedly connected to the roof body structure part of the roof area of ​​the passenger car in the state of being mounted on the vehicle side of the shielding device 1. The supporting frames 2a to 2c have a front part 2a, two side parts each with a guide profile assembly 2b, and a rear part 2c. In the state of being mounted on the vehicle side, the front part 2a and the rear part 2c extend in the transverse direction of the vehicle. Two opposing guide profile assemblies 2b extend in the longitudinal direction of the vehicle in the state of being mounted on the vehicle of the supporting frames 2a to 2c, wherein the opposing guide profile assemblies 2b are oriented parallel to each other. The front part 2 , the two side parts with the guide profile components 2 b and the rear part 2 c are connected to one another in a form-rigid manner to form a quadrilateral frame, ie to form supporting frames 2 a to 2 c .

[0024] The front part 2a of the supporting frame carries a roller blind shaft 5 extending in the vehicle transverse direction in the assembled operating state of the screening device 1, which is rotatably supported in a pot-shaped recess of the front part 2a by means of two bearing modules 6. The roller blind web 3 designed as a textile sheet-like structure is held on the roller blind shaft 5 in a rollable and unrollable manner. The roller blind web 3 is fixedly connected in its front end region in the unwinding direction to a dimensionally stable extension profile 4, which extends in the vehicle transverse direction over the entire width of the roller blind web 3. The extension profile 4 is provided with a locking element 10 at its opposite ends, which is respectively inserted into the open end side of the extension profile 4 and is fixedly connected to the extension profile 4. Each locking element 10 is supported in a corresponding guide channel of the guide profile assembly 2b of the supporting frame so as to be slidable along the guide channel and thus along the guide profile assembly 2b.

[0025] In order to shift the locking element 10 used as a driver for pulling out the profile 4 and the roller blind web 3, a drive system is provided, which has an electric drive motor 7 and two drive transmission systems 8 designed as pitch cables. The drive motor 7 is centrally positioned in the lower area of ​​the front part 2a of the supporting frame 2a to 2c and is coupled to a transmission device not shown in detail, which drives the two drive transmission systems 8 synchronously. The pitch cables used as the drive transmission system 8 are laid from the drive motor 7 to the oppositely arranged guide profile components 2b in the front part 2a and extend through the corresponding guide profile components 2b. In order to guide the pitch cables, a receiving channel not shown in detail is provided in the front part 2a. The corresponding guide grooves in the guide profile components 2b for guiding the drive transmission system 8 are parallel to the guide channel structure of the locking element 10 for pulling out the profile 4. Each of the two drive transmission systems 8 is coupled to the corresponding locking element 10 in a form-locking manner by means of a coupling element 11. The length of each drive train 8 is approximately twice the length of the corresponding lateral guide profile assembly 2b for guiding the corresponding locking element 10. In order to be able to linearly guide this large length of the drive train 8, the receiving channel in the front part 2a is also extended to the other side. These sections serve as unloaded guidance for the sections of the drive train that are not in traction or propulsion operation. The design of the receiving channel of the front part 2a and the function and layout of the drive train 8 are known from the prior art.

[0026] The roller blind 3 can be Figures 1 to 3 The visible functional position, which is at least largely wound up, is displaced between a shielding position, which is pulled out along the guide profile assembly 2b to the rear, i.e., to the rear part 2c. In this case, the pull-out profile 4 is displaced in parallel from front to rear between the two guide profile assemblies 2b by means of the synchronous drive of the two drive trains 8. By the displacement of the pull-out profile 4, the roller blind web 3 is forcibly unwound from the roller blind shaft 5 and extends over the entire length and width of the opening delimited by the supporting frame. The length and width of the opening correspond at least largely to the area of ​​the glass roof area to be shaded.

[0027] The roller blind web 3 is provided with a lateral guide strip 9 on its opposite, longitudinally extending side edges, which extend over the entire length of the roller blind web 3 on each longitudinal side of the roller blind web 3 and are fixedly connected to the corresponding side edge of the roller blind web 3. Each lateral guide strip 9 is sewn to the corresponding side edge of the roller blind web 3 along the center line of the lateral guide strip 9, so that a cross-sectional T-shaped connection is produced between the lateral guide strip 9 and the side edge of the roller blind web 3. The lateral guide strip 9 has a higher rigidity than the roller blind web 3 and is used to maintain a lateral tension in the vehicle transverse direction over the entire length of the corresponding unwound part of the roller blind web 3 when the roller blind web 3 is unwound from the wound rest position, so as to avoid sagging of the roller blind web 3 in the unwound shielding position. For this purpose, the two lateral guide strips 9 are guided in a linearly movable manner in the opposite guide profile components 2b. For this purpose, the two guide profile components 2 b each have a guide groove (not shown in detail) which laterally supports the lateral guide strip 9 in the vehicle transverse direction and guides it in a slidable and linearly movable manner in the vehicle longitudinal direction.

[0028] The two bearing modules 6 each have a bearing journal 12 for rotatably supporting the roller blind shaft 5. In addition, each bearing module 6 serves to guide the corresponding drive train 8 from the corresponding receiving channel of the front part 2a further into the corresponding guide channel of the corresponding guide profile component 2b. Finally, each bearing module 6 has a parking receptacle 16 for securing the corresponding locking element 10 in the rest position of the extension profile 4. In addition, each bearing module 6 is provided with a plug guide pointing to the corresponding guide profile component 2 in order to achieve a flush attachment of the bearing module 6 to the facing end side of the guide profile component 2b.

[0029] In addition, with the help of Figures 5 to 9 As can be seen, the bearing module 6 is provided with a support guide 14 which is arranged according to Fig. 9 The support guide 14 can be received by means of a plug section in a complementary plug-in molding 13 of the bearing module 6 and can thus be connected to the bearing module 6 without tools and nevertheless firmly. Figures 5 to 7As can be clearly seen, the support guide 6 has a guide profile section 17 for linearly movably guiding the lateral guide strips 9 of the roller blind web 3. The guide profile section 17 (also referred to only as profile section 17) is transverse to the extension direction of the roller blind web 3 and thus forms a positively locking support wall in the vehicle transverse direction in the state of the screening device 1 fixedly mounted to the vehicle, in order to prevent the lateral guide strips 9 from deflecting toward the center of the vehicle. The lateral edges of the roller blind web 3 are connected in the region of the lateral guide strips 9 so that when the roller blind web 3 is in the at least partially extended functional position, the roller blind strips adjacent to the lateral guide strips 9, which are not visible, extend from the central longitudinal region of the lateral guide strips 9 toward the center over the surface of the support guide 14. The lateral edges are connected to the lateral guide strips 9 along the center line of the lateral guide strips 9, while in the region of this center line a pivotable movement is formed between the lateral guide strips 9 and the lateral edges of the roller blind web 3. In cross section, the lateral end edges of the side edges of the roller blind web 3 are therefore connected in a T-shaped manner to the lateral guide strips.

[0030] With the help of Figure 3 The supporting guide 14 is shown schematically. It can be seen there that the roller blind web slides over the relatively sharp front face of the supporting guide 14 when the extension profile 4 is displaced. In order to prevent the roller blind web 3 from being damaged at the transition to the corresponding lateral guide strip 9 when the roller blind web 3 enters the bearing module 6 and then the guide profile assembly 2b, the supporting guide 14 additionally has a guide tab 15 which projects in the direction of the bearing journal 12 of the bearing module 6 and thus in the direction of the roller blind shaft 5 and is designed to be elastically flexible. Figures 5 to 8 As can be seen in Figures 9 and 10, the guide tabs 15 are inclined in a curved manner forward and downward relative to the surface of the support guide 14. Figures 5 to 9 The unloaded rest position of the guide tab 15 can be seen. Figure 7 and Figure 8 If the roller blind web (not shown) rests on the guide tab 15, the guide tab 15 is forcibly prestressed downwards, wherein the guide tab 15 thus supports the roller blind web 3 directly adjacent to the lateral guide strip 9 from below. The guide tab 15 is integrally formed on the support guide 14 and protrudes freely forwards from the upper profile section of the support guide 14 at the front side. Figures 5 to 9As can be clearly seen, the guide tabs 15 are laterally offset in the transverse direction relative to the profile sections 17 for the lateral guide strips 9. In the completely assembled state of the bearing module 6, the support guides 14 are attached flush to the respectively adjacent end sides of the guide profile assembly 2b. As a result, the support tabs 15 form a gentle deflection of the roller blind web when it slides along the support guides 14 of the bearing module 6 and in the direction of the guide profile assembly 2b. This reliably prevents damage to the roller blind web at its transition to the lateral guide strips 9 during operation of the screening device 1.
