Description

[0001] The invention relates to a protective device for a motor vehicle interior, comprising two guide channels, each extending longitudinally parallel to a longitudinal axis, a flexible surface structure that can be displaced along the longitudinal axis between a protective position and a rest position, and at least two guide bands, each connected to a lateral edge region of the flexible surface structure, and each of which is slidably movable along the longitudinal axis and positively locked in each of the guide channels along the transverse axis, wherein the flexible surface structure is held on the guide channels by means of the guide bands stretched outwards along the transverse axis and can be displaced between the protective position and the rest position along the guide channels.

[0002] Such a protective device is known from DE 10 2014 223 022 B3 and is designed as a shading device for a motor vehicle interior. In the known protective device, the lateral edge regions of the flexible surface structure have thin connecting strands made of metal, which are welded to the respective guide band.

[0003] Furthermore, protective devices of this type are known from the prior art in which the guide strips are made of plastic and are sewn and / or glued to the edge areas of the flexible surface structure.

[0004] For example, DE 10 2005 040 758 A1 discloses a protective device in which the edge regions of the flexible sheet structure are each sewn to a guide band. The guide bands each have recesses arranged on an inner edge of the respective guide band that points inwards along the transverse axis. These recesses form a toothed inner edge of the respective guide band. A seam runs within each recess to connect it to the edge region of the flexible sheet structure.

[0005] The object of the invention is to provide a protective device of the type mentioned above, which offers advantages over the prior art. In particular, simplified manufacturing and a reliable connection between the guide belts and the flexible surface structure are to be achieved.

[0006] This problem is solved by providing a protective device with the features of claim 1. Advantageous embodiments are specified in the dependent claims. The wording of the claims is incorporated herein by reference.

[0007] In the protective device according to the invention, the lateral edge regions of the flexible sheet structure each have a series of slots. The slots extend from a top surface to a bottom surface of the flexible sheet structure. The guide strips each have a series of tabs. The tabs project laterally outwards along the transverse axis and form a toothed outer edge of the respective guide strip. The tabs are pushed outwards along the transverse axis through the slots, thereby positively connecting the toothed outer edges to the respective edge region of the flexible sheet structure. The solution according to the invention allows for a particularly simple yet reliable connection between the guide strips and the edge regions of the flexible sheet structure. The solution according to the invention eliminates the need for complex sewing, gluing, and / or welding of the edge regions to the guide strips.This significantly simplifies the manufacturing and assembly of the protective device and results in considerable cost savings compared to prior art solutions. The lateral edge regions of the flexible surface structure can also be referred to as longitudinal sides. The lateral edge regions are opposite each other along the transverse axis. Each edge region has a series of slots. Preferably, the series of slots extends over the entire length of the respective edge region. The guide strips extend along the transverse axis between an outer edge and an inner edge, the outer edge being toothed due to the series of tabs arranged there. The tabs can also be referred to as projections. Preferably, the series of tabs extends over the entire length of the respective guide strip.For connection to the respective edge region of the flexible sheet structure, the guide strips are guided laterally outwards along the transverse axis, with the tabs leading, through the slots. "Outwards" means along the transverse axis, facing away from a central region of the flexible sheet structure. In the protected position, the flexible sheet structure is stretched flat along both the longitudinal and transverse axes. In one embodiment, the flexible sheet structure is wound up in the rest position, preferably on a winding shaft. In another embodiment, the flexible sheet structure is also stretched flat in the rest position, with the only movement between the protected position and the rest position being a simple displacement of the flexible sheet structure along the longitudinal axis. The slots can be formed in the flexible sheet structure in any manner suitable for the present purpose.The tabs can have any shape suitable for the intended purpose and – in plan view – can be, for example, serrated, corrugated, angular, specifically rectangular, trapezoidal, and square, and / or rounded. In one embodiment, the tabs lie flat on the upper surface of the flexible sheet, with the remaining sections of the guide band lying flat on the underside of the flexible sheet. In another embodiment, the tabs lie flat on the underside of the flexible sheet, with the remaining sections of the guide band lying flat on the upper surface of the flexible sheet. The positive locking between the outer edges and the respective edge region acts outwards along the transverse axis, i.e., unilaterally. Along the longitudinal axis, the positive locking acts bilaterally, i.e., forwards and backwards.By inserting the tabs into the slots and the flat arrangement of the guide band in the edge area, a positive fit is achieved in the thickness direction of the flexible surface structure, i.e. along a vertical axis, at least in the fully assembled state of the protective device.

[0008] In this embodiment of the invention, the guide strips are connected to the flexible sheet structure exclusively via their toothed outer edges. In this embodiment, no additional joining connections are required between the guide strips and the flexible sheet structure. This allows for particularly simple and cost-effective manufacturing.

[0009] In a further embodiment of the invention, additional joining connections are provided between the guide strips and the sheet structure. These additional joining connections serve to ensure a positive fit between the respective toothed outer edge and the edge region of the flexible sheet structure. The additional joining connections can be formed in any manner suitable for the present purpose, for example, as a seam, adhesive bond, and / or weld.

[0010] In a further embodiment of the invention, the guide bands are made from a metal strip. This embodiment of the invention is based on the consideration that guide bands for protective devices of this type are often made of PTFE plastic. Such plastics are not entirely harmless to health and can therefore be perceived as disadvantageous. By manufacturing the guide bands from metal strip, the use of PTFE plastic can be avoided. In addition, the tabs can be formed particularly simply, for example, by processing the outer edge of the guide bands with a suitable cutting method. For example, the tabs can be cut out of the metal strip, for instance, by laser. Alternatively, the tabs can be punched out.

[0011] In a further embodiment of the invention, the metal band is a spring steel band that can be automatically transformed from a flat, longitudinally extended configuration into a spirally wound configuration. This embodiment of the invention is particularly advantageous when the flexible sheet structure is wound up in its rest position. In this case, the guide bands made from the spring steel band cause the flexible sheet structure to automatically return from the protective position to its rest position. This eliminates the need for a separate spring motor or other winding motor for winding the flexible sheet structure. The design and manufacture of the protective device are thus further simplified.

[0012] In a further embodiment of the invention, the guide strips have a sliding coating at least on the toothed outer edges and / or the tabs. The sliding coating reduces friction when inserting the tabs into the slots. This reduced friction simplifies the assembly of the guide strips onto the flexible surface structure. Furthermore, it prevents damage to the slots when inserting the tabs.

[0013] In a further embodiment of the invention, the guide strips have a ground surface and / or a ground edge, at least on the toothed outer edges and / or the tabs. The ground surface and / or the ground edge reduces friction when inserting the tabs into the slots. This results in the advantages already disclosed with regard to the preceding embodiment. Furthermore, the ground surface and / or ground edge improves the fatigue strength of the guide strips by preventing cracking in the area of ​​the toothed outer edges. In one embodiment, the toothed outer edges each have rounded inner corners. This also prevents cracking.

[0014] In a further embodiment of the invention, the flexible sheet structure in the area of ​​the slots has protection against tearing and / or fraying. This protection prevents damage to the slots by the tabs both during assembly and operation of the protective device. The protection can be designed in any way suitable for the present purpose. For example, the flexible sheet structure in the area of ​​the slots can be provided with a coating, reinforcement, additional seams, melted edges, or the like.

[0015] In a further embodiment of the invention, the slits are each sewn into the flexible fabric in the manner of a buttonhole and each has a circumferential seam. This embodiment of the invention allows for particularly simple production of the slits. Sewing the slits into the flexible fabric enables particularly simple manufacturing. Furthermore, the circumferential seam provides protection against tearing and / or fraying of the respective slit.

[0016] In a further embodiment of the invention, the flexible surface structure is made of a thermoplastic material, wherein the slots are fused into the flexible surface structure and have a circumferential fused edge. This embodiment of the invention also allows for a particularly simple formation of the slots and thus a further simplified manufacturing of the protective device. The circumferential fused edge protects each slot against tearing and / or fraying. In one embodiment, the slots are fused into the flexible surface structure using a laser beam. In another embodiment, the slots are fused into the flexible surface structure using a heated tool, for example, a hot knife or the like.

[0017] In a further embodiment of the invention, the guide strips are each curved along the transverse axis. In one embodiment, the upper surface of each guide strip is concave and the lower surface is convex. This curvature of the guide strips allows for an even better connection with the flexible sheet structure.

[0018] In a further embodiment of the invention, the tabs have different widths along the transverse axis. This simplifies the insertion of the tabs into the slots.

[0019] In a further embodiment of the invention, the tabs are arranged at different intervals along the longitudinal axis. Alternatively or additionally, the tabs can be of different lengths. In a further embodiment of the invention, the slots are arranged at different intervals along the longitudinal axis. Alternatively or additionally, the slots can be of different lengths.

[0020] The invention further relates to an arrangement for a protective device for a motor vehicle interior, comprising a flexible surface structure that is displaceable along a longitudinal axis between a protective position and a rest position, and at least two guide bands, each connected to a lateral edge region of the flexible surface structure, and configured to be slidably movable along the longitudinal axis and positively locked in a guide channel along a transverse axis. In the arrangement according to the invention, the lateral edge regions of the flexible surface structure each have a series of slots. The slots each extend from a top surface to a bottom surface of the flexible surface structure. The guide bands each have a series of tabs. The tabs each project laterally outwards along the transverse axis and form a toothed outer edge of the respective guide band.The tabs are pushed outwards along the transverse axis through the slots, thereby positively connecting the toothed outer edges with the respective edge region of the flexible sheet structure. The arrangement according to the invention can also be referred to as a roller blind. The roller blind has a particularly simple construction. For further advantages arising from this, reference is made to the disclosure relating to the protective device according to the invention. Embodiments of the arrangement according to the invention are derived mutatis mutandis from embodiments of the protective device according to the invention.

[0021] The invention also relates to a motor vehicle with a protective device according to the preceding description.

[0022] Further advantages and features of the invention will become apparent from the claims and from the following description of a preferred embodiment of the invention, which is illustrated with reference to the drawings.

[0023] They show: Fig. 1 in schematic perspective view an embodiment of a protective device according to the invention, which is arranged in the form of a shading device in a glass roof area of ​​a passenger car, Fig. 2 a schematic top view of a flexible surface structure of the protective device according to Fig. 1, where the flexible surface structure is shown cut off on both sides in the longitudinal direction, Fig. 3 in schematic top view a guide band of the protective device according to Fig. 1, where the guide belt is shown cut off on both sides in the longitudinal direction, Fig. 4 the guide belt after Fig. 3 in a schematic cross-section along a section line IV-IV according to Fig. 3, Fig. 5, Fig. 6 the flexible surface structure according to Fig. 2 together with two guide belts according to Fig. 3, which are attached to the lateral edge areas of the flexible surface structure, in a schematic bottom view ( Fig. 5) and a schematic top view ( Fig. 6) Fig. 7 in schematic cross-sectional representation of one of the edge areas of the flexible surface structure together with the relevant guide band and a guide channel of the protective device according to Fig. 1 along a section line VII-VII according to Fig. 6 and Fig. 8 one of the Fig. 7 corresponding sectional view along a section line VIII-VIII according to Fig. 6.

[0024] According to Fig. 1 is a protective device 1 as a shading device for a glass roof 102 of a passenger car 100. The protective device 1 is arranged in an interior 101 of the motor vehicle 100 and is therefore in Fig. 1 shown with dashed lines.

[0025] The protective device 1 has two guide channels 2, 2', a flexible surface structure 3 and two guide bands 4, 4'.

[0026] The guide channels 2, 2' are each extended longitudinally parallel to a longitudinal axis X and are mounted on the vehicle side in the area of ​​the glass roof 102 in a manner known to a person skilled in the art. The guide channels 2, 2' are hereinafter also referred to as left guide channel 2 and right guide channel 2'.

[0027] The flexible surface structure 3 can be moved along the longitudinal axis X between a protected position and a resting position. In Fig. Figure 1 schematically depicts the protective position. In the protective position, the flexible surface structure 3 is stretched flat along the longitudinal axis X and a transverse axis Y to shade the glass roof 102.

[0028] In the illustrated embodiment, the flexible sheet structure 3 is wound onto a winding shaft 5 in its rest position. The winding shaft 5 is mounted on the vehicle side at a rear end of the glass roof 102 with respect to the longitudinal axis X. The winding shaft 5 is optional and therefore not included in all embodiments of the protective device.

[0029] The guide bands 4, 4' are located at lateral edge areas 31, 31' (see Fig. 2) of the flexible surface structure 3. Hereinafter, the guide bands 4, 4' are also referred to as the left guide band 4 and the right guide band 4'. The guide bands 4, 4' are connected to the flexible surface structure 3 in a manner described in more detail below. The guide bands 4, 4' are each slidably movable along the longitudinal axis X and positively locked in one of the guide channels 2, 2' along the transverse axis Y. The left guide band 4 is held in the left guide channel 2. The right guide band 4' is held in the right guide channel 2'.

[0030] The flexible surface structure 3 is held by means of the guide bands 4, 4' along the transverse axis Y and is guided to the guide channels 2, 2' and can be moved between the protected position and the rest position along the guide channels 2, 2'.

[0031] The flexible surface structure 3 is described in detail in Fig. 2 shown and has a series of slots 32, 32' on each of its lateral edge regions 31, 31'. The lateral edge regions 31, 31' are subsequently also referred to as the left edge region 31 and the right edge region 31'. The arrangement and / or design of the slots 32, 32' in the edge regions 31, 31' is identical. To avoid repetition, reference is therefore primarily made to the left edge region 31 below. What has been revealed regarding the left edge region 31 also applies mutatis mutandis to the right edge region 31'. The slots 32, 32' each extend from a top surface 33 (see Fig. 6) except for one subpage 34 (see Fig. 5) of the flexible surface structure 3.

[0032] The guide bands 4, 4' each have a series of tabs 41, 41', with the left guide band 4 being detailed in Fig. Figure 3 shows that the design of the guide bands 4, 4' is symmetrical with respect to a vertical central longitudinal plane of the protective device 1. To avoid repetition, reference is therefore primarily made to the left guide band 4. What has been revealed regarding the left guide band 4 also applies mutatis mutandis to the right guide band 4'.

[0033] The tabs 41 each project laterally outwards along the transverse axis Y and form a toothed outer edge 42 of the guide band 4.

[0034] In the Fig. 5 and Fig. 6 The guide bands 4, 4' are joined to the respective lateral edge region 31, 31' of the flexible surface structure 3. For this purpose, the tabs 41, 41' are pushed outwards along the transverse axis Y through the slots 32, 32', whereby the toothed outer edge 42, 42' of the respective guide band 4, 4' is positively connected to the corresponding edge region 31, 31' of the flexible surface structure 3.

[0035] Regarding the character level of the Fig. 6. The tabs 41 of the left guide band 4 are pushed from right to left through the slots 32 of the edge region 31. The tabs 41' of the right guide band 4' are pushed from left to right through the slots 32' of the right edge region 31'. The toothed outer edges 42, 42' are thereby positively connected to the flexible surface structure 3 along the transverse axis Y. In addition, there is a positive connection on both sides along the longitudinal axis X, i.e., acting both forwards and backwards.

[0036] In the Fig. 7 and Fig. Figure 8 shows the arrangement of the flexible surface structure 3 and the guide bands 4, 4' in the area of ​​the left guide band 4 engaging with the left guide channel 2. In the illustrated embodiment, the guide channel 2 is formed on a guide rail 20. The guide band 4 engages positively in the guide channel 2 along the transverse axis Y. Furthermore, the guide band 4 is also positively held in the guide channel 2 along the vertical axis Z.

[0037] Further specific features of the embodiment shown are explained below.

[0038] In the illustrated embodiment, the flexible sheet structure 3 extends along the transverse axis Y between a left outer edge 35 and a right outer edge 36. Along the longitudinal axis X, the sheet structure 3 extends longitudinally between a front edge 37 and a rear edge 38. In this case, the rear edge 38 is attached to the winding shaft 5 in a manner known to those skilled in the art and can be wound and unwound. The front edge 37 can, for example, be provided with a pull-out profile. In plan view, the flexible sheet structure 3 has a rectangular shape with straight edges.

[0039] The left edge area 31 has the left outer edge 35 and the right edge area 31' has the right outer edge 36.

[0040] The slots 32, 32' are extended longitudinally parallel to the respective outer edge 35, 36. The outer edges 35, 36 are extended longitudinally parallel to each other.

[0041] In the present case, the edge regions 31, 31' are slotted along their entire length, i.e., provided with slots 32, 32'. The [missing information] is located in the Fig. 2, Fig. 5, Fig. The number of slots 32, 32' (and also tabs 41, 41') shown is purely exemplary.

[0042] In the illustrated embodiment, the slots 32, 32' each have a length L1 extending along the longitudinal axis X. Adjacent slots are spaced apart from each other by a longitudinal distance A1 along the longitudinal axis X. Along the transverse axis Y, the slots 32, 32' are each set back by a distance B1 from the respective outer edge 35, 36. The slots 32, 32' each extend longitudinally, in particular straight, between a rear slot end 321 and a front slot end 322.

[0043] In the illustrated embodiment, the slots 32, 32' are each provided with a protective element P that prevents tearing and / or fraying of the flexible surface structure 3. The protective element P is designed differently in different embodiments.

[0044] In one embodiment, the slits 32, 32' are each sewn into the flexible surface structure 3 in the manner of a buttonhole and have a circumferential seam N. The circumferential seam N acts as protection P.

[0045] In another embodiment, the flexible surface structure 3 is made of a thermoplastic material T, and the slots 32, 32' are fused into the flexible surface structure 3. In this case, the slots 32, 32' have a circumferential fused edge K, which in turn acts as protection P.

[0046] The following are in Fig. 2 Both embodiments (buttonhole with circumferential seam, fused slot with fused edge) are shown together.

[0047] In the illustrated embodiment, the left guide band 4 extends along the transverse axis Y between the toothed outer edge 42 and an inner edge 43. The same applies analogously to the right guide band 4'. Both guide bands 4, 4' extend longitudinally along the longitudinal axis X between a rear end and a front end (without reference numerals). The length of each guide band 4, 4' corresponds approximately to the length of the flexible sheet structure 3. In the thickness direction, the left guide band 4 extends between a top surface 44 and a bottom surface 45. The same applies to the right guide band 4'. In cross-section, the guide bands 4, 4' are each approximately rectangular, with the extent in the thickness direction, i.e., along the vertical axis Z, being significantly smaller than the extent in the width direction, i.e., along the transverse axis Y. The latter is again significantly smaller than the longitudinal extent.

[0048] In the illustrated embodiment, the tabs 41, 41' each have a length L2 extending along the longitudinal axis X. Immediately adjacent tabs are spaced apart by a longitudinal distance A2. In the illustrated embodiment, the tabs 41, 41' each have a width B2 extending along the transverse axis Y.

[0049] The length L1 of the slots 32, 32' and the length L2 of the tabs 41, 41' are coordinated. Specifically, the length L2 of the tabs 41, 41' is slightly shorter than the length L1 of the slots 32, 32'. This simplifies the insertion of the tabs 41, 41' into the slots 32, 32'. The same applies analogously to the distances A1, A2, whereby the distances A2 between adjacent tabs 41, 41' are slightly longer than the distances A1 between adjacent slots 32, 32'.

[0050] In the embodiment shown, the width B2 of the tabs 41, 41' corresponds approximately to the transverse distance B1 of the slots 32, 32' from the respective outer edge 35, 36 of the flexible surface structure 3. When the guide strips 4, 4' are inserted, the respective toothed outer edge 42, 42' is therefore flush with the respective outer edge 35, 36 (see also Fig. 5, Fig. 6).

[0051] In the illustrated embodiment, the guide strips 4, 4' are made from a metal strip M. The metal strip M serves as a semi-finished product for manufacturing the guide strips 4, 4'. In the illustrated embodiment, the toothed outer edge 42, 42' is formed by stamping the metal strip M. Alternatively, the tabs 41, 41' can be cut from the metal strip M by laser beam or other cutting process.

[0052] The metal band M in this case is a spring steel band F. The spring steel band F can automatically transform from a flat, extended configuration into a spirally wound configuration.

[0053] To simplify the insertion of the tabs 41, 41' into the slots 32, 32' and to prevent damage to the flexible surface structure by the tabs 41, 41', the guide strips 4, 4' have a sliding coating C at least on their respective toothed outer edges 42, 42' and / or on the tabs 41, 41'. The sliding coating reduces friction when inserting the tabs 41, 41' into the slots 32, 32'. The sliding coating can be made of any material suitable for this purpose, for example, a plastic, a wax, a grease, or the like.

[0054] In this case, the guide strips 4, 4' have a ground surface S1 and / or a ground edge S2 at least on their respective toothed outer edges 42, 42' and / or the tabs 41, 41'. The tabs 41, 41' are ground on both the upper surface 44 and the lower surface 45 of the guide strip 4, 4'. Furthermore, the toothed outer edge 42, 42' is ground throughout. The ground surface S1 and / or the ground edge S2 prevent burrs, such as those that can occur during stamping. Such burrs can damage the flexible surface structure 3 during assembly or operation of the protective device 1. In addition, the burrs can promote cracking in the guide strips 4 themselves, thereby reducing their fatigue strength. All of this is counteracted by the polished surface S1 and / or the polished edge S2.

[0055] In the illustrated embodiment, no additional joining connections are present between the guide strips 4, 4' and the flexible surface structure 3. The connection is formed solely by inserting the tabs 41, 41' into the slots 32, 32'.

[0056] In the illustrated embodiment, the tabs 41, 41' are pushed from the underside 34 onto the upper side 33 through the slots 32, 32'. In the inserted state, the tabs 41, 41' lie flat on the upper side 33 of the flexible sheet structure (see in particular the figure). Fig. 7, Fig. 8) The toothed outer edge 42, 42' is therefore located on the upper surface 33 of the flexible surface structure 3. In contrast, the inner edge 43, which faces away from the toothed outer edge 42, 42', is located on the lower surface 34 of the flexible surface structure 3.

[0057] In the illustrated embodiment, the guide channel 2 has an undercut 21 arranged along the vertical axis Z between the underside 34 of the flexible sheet structure 3 and the upper side 44 of the guide band 4. At the lateral edge regions 31, 31', the underside 34 rests on an upper side of the undercut 21. Apart from the tabs 41, 41', the upper side 44 of the guide bands 4, 4' rests against the underside of the undercut 21.
