Description

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. Such a protective device is made from the DE 10 2014 223 022 B3 The device is known and 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. 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. For example, from the DE 10 2005 040 758 A1 A protective device is known 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. 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. 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. 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 solutions known from the prior art. The lateral edge regions of the flexible sheet structure can also be referred to as longitudinal sides. The lateral edge regions are positioned 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. To connect 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 facing away from a central region of the flexible sheet structure along the transverse axis. In the protected position, the flexible sheet structure is stretched flat along 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 a further embodiment, the flexible surface structure is also stretched across its entire surface in the rest position, whereby a mere displacement of the flexible surface structure along the longitudinal axis is provided between the protective position and the rest position. The slots can be configured for any position relevant to the present application. The tabs must be incorporated into the flexible sheet structure in a manner suitable for the intended purpose. The tabs
