Description

The present disclosure relates to a roller cover for a motor vehicle and/or a motor vehicle comprising the roller cover.

In order to avoid or prevent a view into the luggage compartment of a motor vehicle, e.g. a passenger car, a roller blind can be used.

Known roller blinds are usually attached in the longitudinal direction of the vehicle behind a second (or last) row of seats in the motor vehicle, whereby the roller blind can be designed, for example, as a tarpaulin rolled up in a cassette. This tarpaulin can be pulled out manually or automatically, thereby closing the luggage compartment. The tarpaulin can be wound up in the cassette using spring tension, so that a free end of the tarpaulin must be attached in the rear area of the luggage compartment in the longitudinal direction of the vehicle, i.e. in the area of the tailgate.

In order to be able to create the desired cover for the luggage compartment, a roller cover or the cassette of the roller cover can usually have a length that corresponds approximately to the width of the luggage compartment or the motor vehicle. However, this can lead to problems if the roller cover is not needed, e.g. in order to be able to use the storage space in the luggage compartment above the attached roller cover. Due to the installation space situation inside the motor vehicle and the length of the roller cover or its cassette, it can be difficult or even impossible to locate the roller cover in a space-saving manner, e.g. under the shelf in the luggage compartment.

The cassettes of the well-known roller blinds are usually not adjustable in length or are equipped with spring-loaded end pieces (so-called "pump gun" mechanism), which allow a length adjustment of, for example, approx. 20 mm and at the same time serve to fasten them in the vehicle.

document EP 1 886 874 B1 describes a luggage cover for motor vehicles comprising two curtains each rollable up in a respective rolling device, the axes of the devices being transverse. The devices are movably connected to one another by a connecting means, the means being arranged to offset the axes of the devices longitudinally so that the luggage cover can be reversibly changed from a use configuration in which the devices extend transversely to a storage configuration in which the devices overlap transversely.

document DE10 2007 061 645 B4 describes a roller cover for a motor vehicle, with a winding shaft arranged in the rear luggage compartment behind or on the rear seats in the transverse direction of the vehicle, which is connected to an edge of a roll-up cover element. And the edge area facing away from the winding shaft is connected to a pull-out rod, which can be hung with its protruding hanging elements in hanging bearings in the luggage compartment, wherein the pull-out rod is designed in several parts with hanging elements that can be adjusted laterally via an adjustment device.

document EP 2 174 839 B1 describes a retaining system for a partition between the passenger compartment and the cargo area of a vehicle, with a rod-like fastening arrangement which can be associated with a tubular pocket which is integrally attached to the first side of the partition. The rod-like fastening arrangement comprises several components, including a substantially rigid metal rod with a free end which is slidably and telescopically housed.

Against the background of this prior art, the object of the present disclosure is to provide a device which is each suitable for enriching the prior art.

The problem is solved by the features of the independent claims. The subordinate claims and the dependent claims each contain optional further developments of the disclosure.

According to this, the problem is solved by a roller cover for a motor vehicle, comprising a tarpaulin, a winding shaft to which the tarpaulin is attached so that it can be wound up and unwound, and a cassette in which the winding shaft is rotatably mounted.

The cassette has a middle piece and at least one end piece, wherein the at least one end piece is arranged on the middle piece so that it can be moved (e.g. telescopically) in a longitudinal direction of the cassette between at least two locking positions. The cassette can also be referred to as a telescopic cassette.

The at least one end piece can be displaceable by at least 50 mm, e.g. 100 mm, in the longitudinal direction of the cassette between the at least two locking positions.

The roller blind described above offers a number of advantages. Among other things, the length of the roller blind can be adjusted by sliding of the at least one end piece, so that the roller cover can be located (or stowed) in a space-saving manner when not in use, e.g. under the floor of the luggage compartment of the motor vehicle. Furthermore, the roller cover can be fastened, e.g. at different positions with different vehicle widths within the motor vehicle, e.g. optionally at a first position behind the rearmost row of seats (in or above the luggage compartment) or at a second position which is closer to a luggage compartment lid and has a smaller vehicle width than the first position.

The roller cover thus advantageously offers the possibility of moving at least one end piece into a locking position, so that at least either a fastening and thus a use of the roller cover in the motor vehicle, or a space-saving location in the motor vehicle when not in use is possible.

By locking (or also: latching, engaging) in one of the at least two locking positions, there is also advantageously no need for a spring-loaded solution, which would be difficult for a user to handle.

Possible further developments of the energy absorber described above are explained in detail below.

The at least two locking positions can comprise a storage position in which the at least one end piece is displaced towards the middle piece and a use position in which the at least one end piece for fastening the roller cover in the motor vehicle is displaced away from the middle piece.

The at least one end piece can be designed as a movable cap (or as an end cap, cover and/or housing) of an end region of the middle piece. The at least one end piece can be designed to be open on one side (towards the middle piece) and/or have a larger cross-section than the middle piece. The middle piece can be designed as a hollow cylinder or at least open on one side (towards at least one end region).

The cassette can have a longitudinal opening (and/or a longitudinal slot) which can be formed at least in sections in the middle piece and the at least one end piece. The tarpaulin can be unwound by pulling a free end of the tarpaulin out through the longitudinal opening.

The roller cover can comprise a locking arrangement for each of the at least one end piece for locking in the at least two locking positions.

The locking arrangement can have a longitudinal guide which is formed in a side surface of the at least one end piece.

The locking arrangement can comprise a guide element which is guided in the longitudinal guide and is fastened to the center piece, the winding shaft and/or a bearing in which the winding shaft is rotatably mounted.

The locking arrangement may include an opening formed in a side surface of the at least one end piece and a locking element inserted into the opening.

The locking arrangement can have at least two locking notches. The at least two locking notches can be formed in an outer side of the middle piece, which faces the opening and/or the side surface of the at least one end piece, for locking the locking element in the at least two locking positions of the end piece.

The locking arrangement can comprise a stop element which is fastened to the center piece, the winding shaft and/or a bearing in which the winding shaft is rotatably mounted.

The locking arrangement can have a stop edge which is formed in the longitudinal opening on at least one end piece for stopping the stop element in one of the at least two locking positions.

The locking arrangement can have at least one, e.g. spring-loaded, locking mechanism to secure the at least one end piece in the at least two locking positions.

A fastening opening can be formed on a front side of the at least one end piece.

A locking arrangement can be arranged in and/or on at least one end piece for the locked reception of a fastening element of the motor vehicle in the fastening opening.

The tarpaulin can be made of an opaque and/or non-transparent material

The winding shaft can be spring-loaded, optionally in such a way that the tarpaulin can be wound up automatically and/or by an external force, e.g. pulling, at the free end the tarpaulin can be unwound in an unwinding direction (or pull-out direction).

The free end of the tarpaulin can have a handle for manually unwinding (or pulling out) the tarpaulin.

The roller cover can have at least one sliding piece, which can be arranged at the free end of the tarpaulin, e.g. protruding laterally and/or in the width direction (or length direction) of the tarpaulin. The at least one sliding piece can be slidably received in a guide of the motor vehicle and can be slidable, e.g. in and against the unwinding direction (or extension direction).

The at least one sliding piece may comprise two sliding pieces which may be arranged in a protruding manner at end portions of the free end which are opposite in the width direction (or length direction) of the tarpaulin.

The roller cover can comprise at least one pivot bearing, optionally two pivot bearings, for the rotatable mounting of the winding shaft. The at least one pivot bearing can be attached within the center piece.

The winding shaft (and optionally at least one pivot bearing) can only be arranged in the middle section.

At least one end piece can be designed in several parts.

The above can be summarized in other words and in a possible more concrete embodiment of the disclosure as described below, whereby the following description is not to be interpreted as limiting the disclosure.

The end pieces of the roller blind, which can also contain a locking mechanism, can be designed to be movable. They can be fully extended so that (e.g. only then) they can be inserted into the designated slots in the vehicle and securely locked. They can be fully pushed in so that the (roller blind) cassette is shorter overall (e.g. 200 mm) and can therefore be stowed away. The end positions can be secured using spring-loaded catches. Furthermore, given the limited space in the vehicle, it may be possible to use the pushed-together roller blind in the rear area of the luggage compartment as a replacement for an existing shelf.

Furthermore, a motor vehicle comprising the roller cover is provided.

The motor vehicle can be a passenger car, in particular an automobile, or a commercial vehicle, such as a truck. The motor vehicle can, for example, be a sport utility vehicle (SUV) and/or have at least three rows of seats.

The roller cover can be attached behind a rearmost row of seats in the motor vehicle and/or in or above a luggage compartment of the motor vehicle.

A longitudinal direction of the roller cover and/or an axis of rotation of the winding shaft can run parallel to a transverse direction of the motor vehicle.

The motor vehicle can comprise at least one fastening element which is arranged on a longitudinal inner side of the motor vehicle, optionally behind a rearmost row of seats of the motor vehicle and/or in or above a luggage compartment of the motor vehicle. The fastening element can be designed to correspond to the fastening opening of the at least one end piece and/or to be received in the fastening opening.

The motor vehicle can comprise at least one guide for the roller blind. The guide can be formed on the longitudinal inside of the motor vehicle, wherein the at least one fastening element can be arranged at and/or at a distance from a (first) end of the guide.

The at least one guide can be designed to slidably receive the at least one sliding piece of the roller cover and/or extend in the longitudinal direction of the motor vehicle.

The at least one sliding piece may comprise two sliding pieces which are arranged in a protruding manner at end portions of the free end which are opposite in the width direction (or length direction) of the tarpaulin.

The motor vehicle can comprise at least one fastening point to which the free end of the tarpaulin can be fastened, optionally suspended, in an unrolled state. The at least one fastening point can be arranged at and/or at a distance from a (second) end of the guide.

When the tarpaulin is unrolled, the luggage compartment of a motor vehicle can be covered at least in sections, or optionally completely.

The unwinding direction (or extension direction) of the tarpaulin can be in the longitudinal direction of the motor vehicle (towards the rear) and/or in the reverse direction of the motor vehicle.

The roller cover (and/or the cassette) can have a shape which can be designed in such a way that the roller cover can be designed (and/or used) at least in sections as a replacement for a storage shelf in the luggage compartment.

What is described above with reference to the roller blind also applies analogously to the motor vehicle and vice versa.

Below, optional embodiments are described with reference to the 1 to 5 described.

• 1 shows schematically a cover roller blind according to the disclosure;
• 2 shows schematically an enlarged section of the cover roller blind in two locking positions; and
• 3 shows schematically an enlarged section of the roller cover with a locking arrangement;
• 4 shows schematically an enlarged section of the cover roller blind with the locking arrangement according to another embodiment; and
• 5 shows schematically an enlarged section of the cover roller blind with the locking arrangement according to a further embodiment.

In the 1 is merely schematically the cover roller blind 1 for a motor vehicle, wherein the cover roller blind 1 comprises a cover tarpaulin 2, a winding shaft 5 to which the cover tarpaulin 2 is fastened so that it can be wound up and unwound, and a cassette in which the winding shaft 5 is rotatably mounted.

The cassette has a middle piece 10 and at least one end piece 11, wherein the at least one end piece 11 is arranged on the middle piece 10 so as to be displaceable in a longitudinal direction of the cassette between at least two locking positions A, B. The cassette can, as in 1 shown, have two end pieces 11, wherein one end piece 11 is arranged at each end region of the middle piece 10.

It is also conceivable that the cassette has only one end piece 11 at one end region of the middle piece 10 and the other end region of the middle piece 10 is, for example, closed or designed for (one-sided) fastening of the roller blind 1 in the motor vehicle.

The cassette has a longitudinal opening 13, which is formed at least in sections in the middle piece 10 and the at least one end piece 11. The tarpaulin 2 can be unwound by pulling out a free end 3 of the tarpaulin 2, e.g. by means of the handle 4, through the longitudinal opening 13.

At the free end 3, sliding pieces 6 are arranged in a laterally protruding manner. These sliding pieces 6 can be slidably received in a guide of the motor vehicle, so that the tarpaulin 2 for covering, for example, a luggage compartment in the motor vehicle, can be pulled out slidably along the guide and thus unwound from the winding shaft.

2 shows the cassette or the at least one end piece 11 in two locking positions A, B, namely a use position A, in which the at least one end piece 11 is moved away from the middle piece 10 for fastening the roller blind 1 in the motor vehicle, and a storage position B, in which the at least one end piece 11 is moved towards the middle piece 10. The at least one end piece 11 can be displaced, for example, by approximately 100 mm between the locking positions A and B.

It can also be seen that the at least one end piece 11 is designed as a displaceable cap of an end region of the middle piece 10. Accordingly, the at least one end piece 11 can be displaced along this end region between the locking positions.

A fastening opening 14 is formed on the front side of the at least one end piece 11. This fastening opening 14 can be designed to accommodate a corresponding fastening element of the motor vehicle when fastening the roller blind 1 in the motor vehicle. To ensure secure fastening, a locking arrangement 15 for lockingly receiving the fastening element of the motor vehicle can be arranged in and/or on the at least one end piece 11. For example, a lock of the locking arrangement 15 can be opened, e.g. via a slide switch, in order to be able to accommodate the fastening element in the fastening opening 14. The lock can then be closed to prevent the fastening element from undesirably slipping out of the fastening opening 14.

The roller blind 1 can further comprise a locking arrangement for each of the at least one end piece 11 for locking in the at least two locking positions A, B. The 3 , 4 and 5 show optional locking arrangements, which can also be combined with each other.

In 3 the locking arrangement has a longitudinal guide 16 which is formed in a side surface of the at least one end piece 11. A guide element (not shown) can be guided in the longitudinal guide and fastened to the middle piece 10, the winding shaft 5 and/or a bearing in which the winding shaft 5 is rotatably mounted. The guide element can be latched at the ends of the longitudinal guide 16, wherein the at least one end piece 11 is located at these ends, e.g. in the latching positions A, B.

In 4 the locking arrangement has an opening 17 which is formed in a side surface of the at least one end piece 11, a locking element 18 which is inserted into the opening 17, and two locking notches 19A, 19B. The two locking notches 19A, 19B are formed in an outer side of the middle piece 10 which faces the opening 17 or the side surface of the at least one end piece 11. The two locking notches 19A, 19B can, for example, be arranged such that the at least one end piece 11 is in the locking position A when the locking element 18 is locked in the locking notch 19A and in the locking position B when it is locked in the locking notch 19B.

In 5 the locking arrangement has a stop element 20 which is fastened to the middle piece 10, the winding shaft 5 and/or a bearing in which the winding shaft 5 is rotatably mounted. Furthermore, a stop edge 21 is formed in the longitudinal opening 13 on at least one end piece 11 for stopping the stop element 20. The stop edge can be designed in such a way that the at least one end piece 11 is in the locking position B when the stop element 20 stops. If the stop element hits an outer end of the longitudinal opening in the longitudinal direction, the at least one end piece 11 can be in the locking position A, for example.
