Out 1 is schematically a cargo space 1 a trained as a combined motor vehicle, with an extendable luggage compartment cover 2 is covered approximately at the level of the lower edge of the side window. The cargo compartment cover 2 consists of a flexible, soft plastic, textile or leather material that comes from a mechanically self-winding cassette 3 is recorded. The cassette 3 has for rolling up corresponding, not shown spring means. In the area covered in the cargo compartment 1 rear side of the cargo compartment cover 2 is a rod-shaped profile 4 arranged. End is on the profile 4 a part which can be swiveled up and down 5 with a handle 6 appropriate.

At each of the side panels 7 of the cargo space 1 is in each case an extending in the vehicle longitudinal direction guide 8th arranged. The ends of the profile 4 form engagement sections 9 (see for example 3a ), in the guides 8th can be performed in the vehicle longitudinal direction. Out 2 it can be seen that the guides 8th For example, are formed as an undercut groove. At the vehicle longitudinal rear end of each of the guides 8th is a cylindrical recess 10 provided in which a twist lock 11 is arranged. The twist lock 11 is rotatable about an axis extending in the vehicle transverse direction. From the recess 10 extends another recess 12 down, the one in the vehicle longitudinal direction forwardly extending section 13 having.

The respective twist lock 11 has a groove-shaped receptacle 14 in which one of the engaging sections 9 can be pushed into it. The twist lock 11 Includes a torsion spring that locks the pivot 11 in the in 3a position shown.

The Arretierungsvorgang the cargo compartment cover can be based on the 3a to 3c clarify. At the far end of the 3a to 3c is a tailgate 15 indicated the motor vehicle. In 3a is the twist lock 11 in a position in which the groove-shaped receptacle 14 forward in the direction of travel or left in 3a is open. If now the user the cargo space cover 2 pulls back, become the engaging sections 9 in the guides 8th Pulled back until she is in the receptacle 14 the twist lock 11 arrive (see 3b ).

If the user in this position the handle 6 pushes down, so is the profile 4 pressed down. This practice the engaging sections 9 a torque on the twist locks 11 out, so that these turn. When the twist locks 11 rotated by more than about 90 °, the cover enters the in 3c pictured position. In this position are the engagement sections 9 a little way in the forward section 13 the recess 12 forward facing the in 3b moved to the position shown. Due to the spring means of the cassette 3 become the engaging elements 9 and therefore the profile 4 against the spring force of the torsion spring of the rotary locks 11 pulled forward, so that in 3c Imaged position is a stable locking position of the cover.

The cargo compartment cover 2 can be opened by allowing the user to grip 6 or the end part 5 pushes up. This will in the recording 14 located engagement sections 9 pushed up so that the twist locks 11 in the in 3a and 3b rotated unlocked position shown. From this position, the spring means of the cassette 3 the cargo compartment cover 2 pull backwards.

At the 4 apparent cover is on the tailgate 15 a swiveling driver 16 attached, the automatic opening of the luggage compartment cover 2 allows. The driver 16 can be from an in 4 shown in dashed lines manually unhooked position in which no automatic opening of the luggage compartment cover can take place in the in 4 solid position shown folded in the opening of the tailgate 15 also the load compartment cover 2 is opened. It may be an un pictured, at For example, be provided as a torsion spring spring means that the driver 16 from the tailgate 15 in the in 4 pulled position shown pivots away.

From the 5a to 5c is the closing of the tailgate 15 and the effect of closing on the cover with the load compartment cover closed. From the 5d to 5f is the opening of the tailgate 15 and the effect of opening on the cover with the load compartment cover closed.

In the position according to 5a is the driver 16 collapsed. When moving the tailgate 15 down (see 5b ) becomes the driver 16 from the end-side part 5 the cargo compartment cover 2 to the tailgate 15 pivoted toward. If the tailgate 15 continue down to the closed position (see 3c ), the driver can 16 be transferred from the torsion spring back to the tilted position back.

When opening the tailgate from the closed position (see 5d ) moves the driver 16 upwards, until he from below at the end-side part 4 the cargo compartment cover 2 is applied. By further movement of the tailgate 15 and the driver 16 upwards is the end part 5 the cargo compartment cover 2 together with the engaging portions 9 pushed upwards (see 5e ). This will turn the latches 11 unlocked and the cargo compartment cover 2 can from the spring means of the cassette 3 to be pulled forward (see 5f ).

In the 5a to 5f clarified automatic opening of the cargo compartment cover 2 can also with a different lock the load compartment cover 2 at the end of the hold 1 will be realized. As an example, the automatic opening can also be realized in an embodiment in which the rotary locks 11 is waived. In this embodiment, the user guides the engaging portions 9 the cargo compartment cover 2 by hand into the forward projecting sections 13 the recesses 12 ,

The embodiment according to the 6 to 7b Accordingly, can also be realized with or without twist locks. In this embodiment, a pivotable carrier 17 at the end part 5 or the handle 6 the cargo compartment cover 2 appropriate. When closing the tailgate 15 can be the driver 17 clockwise (see 7a ) to the end part 5 be folded up, with the driver 17 After reaching the closed tailgate position by a torsion spring can be pivoted out again in the counterclockwise direction (see 7a ).

When moving the tailgate 15 from the closed position (see 7a ) pushes up a protruding section 18 the tailgate 15 the driver 17 and thus the end part 5 the cargo compartment cover 2 upwards, so that this is released and can be pulled back to the front.

Further advantages and features of the present invention will become apparent from the following alternative description of preferred embodiments:
To ensure a smooth, guided movement of the luggage compartment cover, it is advisable to use lateral guide rails. The cargo compartment cover must have a lock in the closed (extended) state, which is released by simply pressing a button and thus retracts the load compartment cover into the self-winding cassette. It is not important whether the lock is released indirectly by means of this button or the lock is released directly. When using a button, it may be attached to the luggage compartment cover or body. For example, the handle can take over the function of the button described.

The Lock can also be opened directly, so without Button. The direction of the keystroke is dependent from the opening direction of the tailgate. The direction of the Key press should not possible in the mutual Lie direction. Currently the key must or must Handle pressed down to open the cargo compartment cover be, a push up would be easier for an automatic opening mechanism.

In the tailgate (or in the tailgate trim) is a driver attached, which can be unfolded, if one automatic opening of the cargo space is desired. By Spring tension (for example, torsion spring, tension or compression spring) provides The driver then always automatically after unhooking. The driver mimics, during the opening movement of the tailgate, pressing the button and thus releases the locking of the luggage compartment cover.

In In one variant, the driver is not positioned in the tailgate, but in the handle (trigger the lock) of the luggage compartment cover. In The tailgate trim must have a space to fold out the driver be kept. The tailgate trim is used when opening the Tailgate to support the driver and thus the Lifting the handle.

It can also be used two carriers, each one far out on the tailgate interior trim and open the lock directly.

at a conventional load compartment cover this must be for loading of the cargo space, after opening the tailgate, with a Hand is unhooked from the two-sided undercuts and becomes then fed automatically by cassette.

By the use of a covering device according to the invention The cargo compartment cover can be opened by a slight upward movement (Rotation of, for example, a maximum of 25 °) of the handle solved and thus retracted from the self-winding cassette become. To this otherwise manual movement to mimic, the tailgate has a driver, so a component (Bar / plate) which is designed hinged. If the user the automatic opening of the luggage compartment cover wishes, he can unhook this driver from the tailgate trim. He then turns himself on by means of tension spring. As the user closes the tailgate, it turns the driver with each further closing the tailgate under the handle of the forward loading compartment cover. If the Tailgate now open, pushes the driver the handle high and thus solves the lock. The load compartment cover can now be fed through the self-winding cassette and the Cargo space is automatically released

In the variant consists only of the difference that the User removes the driver from the handle (trigger of the lock) flipping out. Again, the driver is by means of tension spring on. When opening the tailgate abuts the driver against a projection of the tailgate trim and pushes up the handle with it. Thus dissolves as before described the lock and the load compartment cover is going through the cassette retracted.

In the embodiment according to 4 The folded driver must only press against the profile of the cargo compartment cover from below. Or two drivers are used, which open the two-sided turn locks directly.

• – Das lästige und umständliche Aushaken der Laderaumabdeckung entfällt.
• – Die Hände bleiben frei zum Einladen. Kombiniert mit einer elektrischen Heckklappe sind keine Handgriffe mehr zum Öffnen notwendig.
• – Die zusätzliche Funktion ist an- und abschaltbar.
• – Die zusätzliche Funktion ist sehr kostengünstig darstellbar.

This results in the following advantages:

• - The annoying and awkward unhooking of the cargo space cover is eliminated.
• - The hands remain free to invite. Combined with an electric tailgate, there are no more handles to open.
• - The additional function can be switched on and off.
• - The additional function is very cost-effective.

The The invention is conceived for use on a station wagon. The Load compartment cover is made as in the existing solutions a flexible, soft plastic, textile or leather material, taken up by a mechanically self-winding cassette becomes. The end of the cargo compartment cover that comes out of the cassette, has a profile on which the cargo compartment cover is clamped. The profile of the cargo compartment cover is by means of guide rails guided in both sides. Thus a tilting of the Profiles in the guide rails can be avoided, the profile can slide in the guide rails by means of carriages but also be executed yourself (rectangular or round), that an optimal sliding movement takes place. Furthermore, that can Profile a handle to pull out the cargo compartment cover from the cassette have. The guide rail can through the side part be constructed in one piece or in several parts.

The Twist lock is as a rear extension of the guide rails For example, in the side panels of the left and right trunk paneling executed and clipped there, screwed or riveted. A clip connection is to be preferred. The twist lock is over an angle greater than 90 ° rotatable at the bottom (or as a variant upwards). The leadership the profile (or the slide) goes over the center of rotation out, so that by means of the profile of the luggage compartment cover a rotation (Torque) of the rotation lock can be generated. So that Turn lock for inserting the profile in the horizontal Standing position, the rotation lock by means of spring force (for example Torsion spring, tension spring or compression spring) are pressed / pulled into this position. Is the load compartment cover closed, so the profile in the twist lock introduced and turned over 90 °, allowed the spring force should not be so high that the twist lock automatically moved back to the horizontal position.

Around the twist lock as additional equipment or accessories For sale, the conventional locking can be by hooking be kept in the side panel. When the twist lock is not desired, the connection point for the twist lock covered by a bezel, this can also Simply be clipped.

In the conventional load compartment cover this must be pulled by hand from the cassette to cover the cargo space and threaded with the profile at the end of the cargo compartment cover in an undercut on the right and left interior trim and hooked. To load the load compartment, the load compartment departure After opening the tailgate, with one hand be unhooked on both sides again and then automatically fed by cassette. This hooking and unhooking is cumbersome, as must be threaded on both sides exactly in the undercut.

in the Unlike the existing solution is at the present Invention the profile of the luggage compartment cover on both sides in the guide rails led the trunk side panels. To the load compartment cover in the closed position, the user pulls the Cover, to the rear end stop from the cassette and presses it down (or in a variant up). This is the load compartment cover locked.

The Operation is such that by means of the profile of the end stop pulled out luggage compartment cover a torque in the twist lock can be generated. If now this torque by pressing of the profile is generated down (or up), the rotates Twist lock with the help of the pulling force of the self-winding cassette 90 ° and the profile is fixed with it.

Around to retract the luggage compartment cover, the profile only needs pressed up (or in a variant down) become. The rotation lock rotates and the profile is restored directed into the guide rail, where it by the self-winding Cassette can be fed.

The Operation when retracting is such that by pushing up the profile, the simultaneous pulling force of the cassette and the spring force the torsion spring of the center of gravity is moved in the lock, so that the twist lock rotates. This is again in the horizontal and the profile can again the guide rail drive along to the cassette.
