Description

[0001] The invention relates to a protective device for a vehicle interior with a cassette housing in which at least one flexible protective structure is mounted so as to be able to be wound up and unwound, wherein the cassette housing has a hollow profile with a cross-section that remains constant over its length and is provided with at least one longitudinal slot through which the protective structure can be pulled out of the cassette housing or retracted into the cassette housing.

[0002] Protective devices for the interior of a motor vehicle are generally known. Such a protective device in the form of a load compartment cover and / or in the form of a partition between a load compartment and a passenger compartment of a passenger car has a dimensionally stable cassette housing in which a flexible protective structure is mounted so that it can be wound up and unwound. In a load compartment cover, this is a cover sheet that can be rolled up and unwound and extended approximately horizontally along the load compartment. In a partition device, the flexible protective structure is designed as a partition net that can be stretched vertically across the vehicle and secured in a roof lining area. The cassette housing has a hollow profile made of an extruded light metal profile. The hollow profile is closed at the front by end caps, which are also made of metal.The hollow profile has a longitudinal slot on at least one long side through which the protective structure can be pulled out of the cassette housing.

[0003] The object of the invention is to create a protective device of the type mentioned above which can be produced sustainably.

[0004] This problem is solved by making all walls of the hollow profile from a renewable raw material, in particular wood, preferably bamboo. This means that the dimensionally stable hollow profile can be produced sustainably without great energy expenditure. If the hollow profile is made from wood, the hollow profile is also lighter than the state of the art. The hollow profile can have different cross-sectional shapes. In addition to a square cross-section, a polygonal cross-sectional shape or a cross-sectional shape that is at least partially round can be provided. Because the hollow profile is made from a renewable raw material, resources are conserved. Bamboo is particularly advantageous for the production of the hollow profile because it is a fast-growing plant. Suitable bamboo trunks, from which the bamboo wood is produced in the form of corresponding surface parts, are extremely stable.

[0005] In an embodiment of the invention, the walls are constructed from wooden surface parts that are firmly connected to one another at respective longitudinal edge regions of the hollow profile. The hollow profile made of wood preferably has a square cross-section, similar to known metal hollow profiles. Advantageously, a total of four wooden surface parts are provided on corresponding four longitudinal sides, which are firmly connected to one another in the region of the longitudinal edges of the hollow profile. The wooden surface parts are advantageously made of bamboo wood. The wooden surface parts can be mechanically connected to one another at the longitudinal edge regions in a form-fitting manner, in particular by doweling or toothing. Alternatively, the wooden surface parts can be connected to one another at the longitudinal edge regions in a material-fit or force-fit manner, in particular by gluing or pressing.

[0006] In a further embodiment of the invention, the longitudinal edge areas are mechanically treated after the joining of the wooden surface parts, in particular by machining, preferably by sanding. This ensures that no sharp edges or visible gaps remain.

[0007] In a further embodiment of the invention, the wooden surface parts are constructed in multiple layers. The wooden surface parts can be designed as a laminate made of several wood veneer parts, as plywood, or as several wooden surface layers combined with at least one reinforcing insert.

[0008] In a further embodiment of the invention, external surface areas of the wooden surface parts are post-treated. The post-treatment can be performed mechanically by sanding, planing, milling, or similar machining processes. Alternatively or additionally, the post-treatment can be performed by applying liquid layers, in particular by oiling, staining, or varnishing. Alternatively, the post-treatment can be performed by coating with an additional layer, preferably by lamination with a knitted fabric, a woven fabric, a film, or textile or leather goods.

[0009] In a further embodiment of the invention, the hollow profile is formed by shaping, permanent bending of at least one wooden surface part around a longitudinal axis, in particular by a hot-steaming process. The at least one wooden surface part is thus permanently formed. When the wooden surface part is designed as a multi-layer laminate, this can be achieved by gluing corresponding wooden surface layers together and bending them while the glue is still wet and unfixed. These layers remain fixed in this bent shape until the glue or adhesive has cured. Alternatively, it is possible to achieve non-destructive bending of the at least one wooden surface part by a hot-steaming process.

[0010] In a further embodiment of the invention, the hollow profile is reinforced internally and / or externally by stiffening elements made of renewable raw materials. Such stiffening elements can be wooden profiles that are attached to the inner edges of the longitudinal edge areas of the hollow profile. Alternatively or additionally, fabrics made of natural textile materials such as flax, hemp, cotton, or virgin wool can be laminated on. After the adhesive has cured, this results in stable and consistent stiffening.

[0011] In a further embodiment of the invention, attachments are attached to the hollow profile using mechanical fasteners. Such attachments include end caps, gap covers, supports for an end board of the flexible protective structure, or similar. Screws, clips, claws, rivets, or similar are provided as mechanical fasteners. Alternatively, it is possible to fix the attachments to the hollow profile using a material bond.

[0012] In a further embodiment of the invention, reinforcement elements are provided at the fastening points to prevent the wood material of the hollow profile from splitting open at the fastening points. Fastening points are the points where the mechanical fasteners engage the wood material of the hollow profile to secure the attachments. Suitable reinforcement elements are metal eyelets, metal nuts, plastic reinforcement elements, or reinforcement layers provided in sections, which are applied to an inner or outer surface of the wood material of the hollow profile or inserted between corresponding layers of the wood material.

[0013] In a further embodiment of the invention, the flexible protective structure is provided at a front end region in the unwinding direction with a dimensionally stable endboard made of a panel element made of a wood material. This panel element can be single-layered or multi-layered. If the panel element is constructed from multiple panel layers, these wooden panel layers can be glued or laminated together. Bamboo wood is preferably provided for the panel element.

[0014] Further advantages and features of the invention emerge from the claims and from the following description of a preferred embodiment of the invention, which is illustrated by the single drawing.

[0015] The only drawing shows Fig. 1 shows a perspective view of an embodiment of a protective device according to the invention in the form of a load compartment cover for a vehicle interior of a passenger car.

[0016] A vehicle interior F of a passenger car has a rear seat bench 1 in a rear area, the backrest arrangement of which forms a front end for a cargo space that adjoins a passenger compartment of the vehicle interior F at the rear. A cargo space cover having a dimensionally stable cassette housing 2 is assigned to this cargo space. The dimensionally stable cassette housing 2 extends across a width of the cargo space in the transverse direction of the vehicle and is fixed to the vehicle either on a rear side of the backrest arrangement of the rear seat bench 1 or on opposite side walls of the cargo space. A cover sheet 3, which acts as a flexible protective structure and can be wound up and unwound, is mounted in the cassette housing 2 and is held on a winding shaft that is rotatably mounted in the cassette housing 2.The flexible protective structure 3 has a dimensionally stable endboard 4 at its front end region in the unwinding direction, which is provided with a grip recess to enable manual gripping of the endboard 4 and thus of the flexible protective structure 3. The cassette housing 2 is provided with a longitudinal slot 6 extending over almost the entire length of the cassette housing 2, through which the flexible protective structure 3 can be inserted and removed.

[0017] The cassette housing 2 is formed by a hollow profile that extends with a constant cross-section in the transverse direction of the vehicle over the length of the cassette housing 2 and forms the longitudinal slot 6. The hollow profile has a square hollow cross-section. The winding shaft is arranged in the hollow profile together with the windable and unwindable protective structure 3. The hollow profile is open towards its opposite end faces. These open end areas are each closed by an end cap 5, which is designed as a separately manufactured add-on part. The two end caps 5 are firmly connected to the opposite end areas of the hollow profile of the cassette housing 2.

[0018] The hollow profile 2 is, as the grain in Fig.1 is removable, is made of wood, in this case of bamboo. For this purpose, four wooden surface parts made of bamboo are selected, each forming a long side of the hollow profile of the cassette housing 2. A wooden surface part facing rearwards towards the rear of the vehicle also forms the long slot 6. The four wooden surface parts are butted together at right angles by their long edge areas. In the area of ​​these long edge areas, the connected wooden surface parts made of bamboo are mechanically treated by sanding them together to form curves. The two end caps 5 can also be made of wood, preferably of bamboo. After the hollow profile made of bamboo has been manufactured, these are attached to the opposite end faces of the hollow profile and firmly connected to the hollow profile.
