In view of the cited prior art, the development of a cover for a gap behind a rear seatback in a vehicle still offers room for improvement.

The invention is therefore based on the object, a cover for a gap of a vehicle, which is provided between a rear seat back of the vehicle and extending in the vehicle transverse direction luggage compartment cover of the vehicle to provide, which is structurally simple and is relatively easy to handle.

According to the invention the object is achieved by a cover having the features of claim 1. It should be noted that the features listed in the following description as well as measures in any technically meaningful way can be combined with each other and show other embodiments of the invention. The description characterizes and Specifies the invention in particular in connection with the figures additionally.

There is provided an improved coverage for a gap of a vehicle. For example, the gap is a gap between the parcel shelf and the rear seat back or a gap between the rear seat back and the tailgate, the cover according to the invention would fulfill the task of classic luggage compartment cover. However, it is preferably a gap, which is provided between a rear seat back of the vehicle and a vehicle transverse direction extending housing of a luggage compartment cover of the vehicle. The cover according to the invention has a flexible surface element and at least one support element arranged on the surface element. The support member is in a withdrawal from the housing in a second stable position can be transferred and has the flexible surface element free. The support element is designed to be in the gap extending arrangement, in particular in the vehicle longitudinal direction between the rear seat back and the housing of the pastry space cover. The support element is, for example, positively, positively and / or materially connected to the surface element.

Preferably, the surface element is a textile surface element, wherein the support element is sewn to the surface element. The support member may be surrounded by a portion of the surface element, so be included and / or be included in sewn pockets in the surface element. So a quasi-uniform appearance is ensured, with a sufficient attachment is always given so that the free-bearing property of the support element acts on the surface element.

A free-bearing design of the support element means in the context of the invention, a surface element supporting function of the support element waiving and need additional support of the surface element, for example, on the inner lining of the passenger compartment of the vehicle.

Targeting is provided that the support member is formed as a bistable spring element, wherein the bistable spring element can be moved from a first stable position to a second stable position and back. In the second stable position, a gap-covering arrangement of the cover is effected by the bistable spring element. In the first stable position is caused by the bistable spring element, the gap at least partially releasing arrangement of the cover. In other words, the stable layers of the bistable support element permit, on the one hand, a position of the cover covering the gap and, on the other hand, a position of the cover which releases the gap. For example, in the second stable position of the bistable spring element whose position corresponds to that of a cantilevered, projecting into the gap, substantially rectilinear or slightly curved cantilever, while the support element in the first stable position occupies a relation to the second layer strongly curved position, and the gap at least partially releases.

The use of the bistable spring element achieves a comparatively easy-to-handle covering which requires comparatively few fastenings and in particular no fixations, e.g. on side areas of the vehicle is required. Especially the latter lowers the production costs and the weight of the vehicle.

The bistable spring element is, for example, one made of spring steel sheet, which has been treated by punching, bending, edging and / or embossing in such a way that it is capable of assuming the two stable layers. In this respect, the support element, so the bistable spring element can also be referred to as a bistable spring band.

Preferably, on both sides of the textile surface element, ie at its respective outer longitudinal edges in each case a support element, that is arranged in each case a bistable spring element or band. The support element has an identical longitudinal extent to the surface element longitudinal extent when the surface element is in the maximum unrolled or maximum extended state.

According to a preferred embodiment, it is provided that in the first stable position of the bistable spring element, the surface element and the bistable spring element are in a wound state.

By manual unwinding, so extract the textile surface element together with the preferably on both sides arranged support element via a respective forced operation, the bistable spring element is spent in the unwound portion of the bistable surface element in the second stable position.

The positive guide is disposed within said housing and forces the respective support element in a bias, so that the support element, so the bistable spring band is in the extended state of the cover in the second stable position.

For this purpose, the forced operation seen in the transverse direction on a curved course. The curved course has a curvature, the has her zenith in the middle of forced guidance. The curvature can be convex or concave. It is expedient if the support element, so the bistable spring band gets a likewise convex or concave shape, the course of the positive guidance corresponding forced upon the extract of the textile surface element. This forced shape keeps the support element until it is rolled back into the housing, that is transferred to the first stable position.

For example, the surface element and the bistable spring element are wound around a rotatably mounted winding rod or tube.

According to a preferred embodiment, it is thus provided that the cover has a housing in which the surface element and the at least one support element are at least partially received and the housing, if necessary, preferably adapted to the respective width of the gap, are removably mounted, so that the cover can be easily adapted to the gap or its width seen in the longitudinal direction of the vehicle.

According to a further embodiment, a winding mechanism is further provided. Such a winding mechanism is basically known and has, for example, a blocking position and a release position. In the blocking position, the cover is held securely in its respective extended position adapted to the gap, wherein the support elements arranged on both sides are in the second stable position, ie deformed convexly or concavely, that is, the surface element is biased cantilevered. The release position is reached after the blocking position by the support element and the surface element are unwound together again over a predetermined release length, so that the winding mechanism causes an independent curling. In this case, the surface element is wound together with the preferably on both sides arranged support element. During winding, the support element passes through the positive guide, wherein the imposed convex or concave shape can be maintained seen in the transverse direction. However, it is possible that the imposed convex or concave shape is abandoned in the wound state, so that the support member each having a rectilinear configuration. This is to be understood that the surface element is rolled up like a spiral, together with the supporting elements arranged thereon. However, the imposed curvature can be seen transversely seen.

The cover may be secured in one embodiment to the rear seat back. Preferably, however, it is provided that the cover is arranged on the opposite, the luggage compartment cover associated side of the gap. More preferably, it is provided that it is attached to the already existing luggage compartment cover for arrangement in a vehicle transverse direction of a vehicle and thus forms a unit with this. It is preferred if a common housing is provided. As a luggage compartment cover is understood as one that is designed to cover, if necessary, the cargo area of the vehicle with another surface element. For example, an additional, optionally further winding mechanism is provided for this further surface element.

Further advantageous embodiments of the invention are disclosed in the subclaims and the following description of the figures. Show it

4 a sectional view of the cover according to the invention 1 .

5 a frontal view of a side region of the cover according to the invention 1 , and

6 a plan view of a side region of the cover according to the invention 1 ,

In the different figures, the same parts are always provided with the same reference numerals, which is why these are usually described only once.

Based on 1 should the arrangement of the cover according to the invention 1 ( 2 ). For example, vehicles of the combination type, so combinations have a luggage space, which is not separated from the intended for the passengers interior by a body separation. As a rule, such vehicles only have a luggage compartment cover 2 usually in the form of a Ausziehrollos. Furthermore, as a variable adjustment of the rear seat back 3 is desired in the vehicle longitudinal direction, remains depending on the position of the rear seat back 3 an undesirable gap 4 between the rear seat back 3 and the luggage compartment cover 2 ,

Such a gap 4 allows viewing in the luggage compartment and is therefore undesirable, not least for reasons of burglary protection. Around To prevent this is the in 2 shown cover 1 intended.

The cover 1 indicates with respect to the forward direction of travel of the vehicle behind the rear seat back 3 arranged housing 5 on. This has a slot 6 ( 4 ) and is otherwise closed. The slot 6 is on one of the vehicle front side facing side of the housing 5 arranged. Out of this slot 6 of the housing 5 occurs a textile surface element 8th from, which by way of example by means of two laterally on the side edges of the textile surface element 8th arranged, the surface element 8th freely supporting support elements 9 is supported.

The support elements 9 are on the surface element 8th attached and together with the surface element 8th also in the case 5 arranged as needed to the housing 5 over the slot 6 together with the surface element 8th according to the width of the gap 4 if necessary, be removed by pulling.

The support elements 9 are with the preferred textile surface element 8th force, substance, and / or positively connected, for example, sewn. The surface element 8th can the respective support element 9 laterally, so that it is virtually invisible, so that a uniform appearance is given.

In 2 is only an outer side portion of the cover 1 shown, leaving the second on the opposite flank of the surface element 8th provided support element 9 in the 2 to 6 not shown.

At the support element 9 each is a bistable spring element, ie a bistable spring band.

The support element 3 can be two stable layers 10 and 11 taking.

In one outside the case 5 located position, ie in the extended position, the support element 9 the second stable position 10 on, what in the 2 . 3 and 6 is recognizable. In the inside of the case 5 arranged position, ie in the wound position, the support member, the first stable position 11 on what's in the 4 is recognizable.

The second stable position 10 becomes the respective support element 9 by means of a forced operation 12 imposed. According to the number of support elements 9 are also corresponding forced tours 12 intended. In this respect, the housing has 5 for the respective longitudinal side of the textile surface element 8th each a forced tour 12 on. The forced tours 12 are each inside the case 5 arranged and are located just before the slot 6 , again 4 is removable. The forced tours 12 are on a lid 16 of the housing 5 set, for example screwed, glued or otherwise secured. The lid 16 is executed only by way of example ribbed.

The forced tour 12 Each has a curved course with a curvature whose zenith 13 in about the middle of the forced tour 12 is arranged. The width of the forced guidance 12 seen in the transverse direction corresponds approximately to the width of the respective support element 9 , where the forced guidance 12 still has a side game, like the 5 is removable. Again 5 can be seen further, shows the forced operation 12 a convex course, so a curvature, which is curved towards a vehicle floor down.

Will now be the textile surface element 8th together with the two support elements 9 out of the case 5 pulled out, the respective support element 9 the form of forced tours 12 imposed. In this respect, the support elements 9 in the second stable position 10 forced, so to speak, so biased that the support elements 9 , Thus, the bistable spring bands along the pulled-out longitudinal extent have a convex course. In this second stable position, the support elements remain 9 at least until the textile surface element 8th should be rolled back, and the support elements 9 the first stable situation 11 take in the 4 is indicated.

The slot 6 is in the field of forced guidance 12 , ie in the respective end area 14 Corresponding to forced operation 12 arched. Between the ends arranged arched areas 14 has the slot 6 a rectilinear middle section 15 on. Of course, the slot can 6 in the respective end area 14 also executed in a straight line, the slot 6 but then at least there in his passage should be such that the means of forced operation 12 imposed second stable position 10 the support elements 9 , so their imposed domed shape can be maintained.

The forced tour 12 can be designed so that these on their inside 17 has a rectilinear shape, which extends along the longitudinal extension of the forced operation 12 changed to the arched shape, leaving the support element 9 each outside the domed shape is imposed. The outside 18 the obsession 12 is of course to the slot 6 oriented. The forced tour 12 So can two areas of different shape have, which pass steadily, so gently into each other, to the respective support element 9 to shape accordingly. Will now be the surface element 8th recovered, causes the forced operation 12 a lifting of the curved forced form of the support element 9 and converts this into the flat shape, allowing easy rolling up inside the case 5 possible (first stable position 10 ). Depending on the winding direction, the support element 9 So either the first stable position 10 or the second stable position 11 imposed. This applies only to the section which also the inside 17 the obsession 12 happens. The support element 9 thus has a section 19 on that in the second stable position 10 is and a section 20 in the first stable position 11 is. This is to be understood that the support element 9 together with the surface element 8th just so far out of the case 5 is pulled out, that the gap 4 is covered, what the section 19 represents. But there is still a rest, so the section 20 inside the case 5 arranged in the rolled up state.

For example, in the housing 5 a winding mechanism similar to a roller blind provided and the support elements 9 and the textile surface element 8th are around one in 4 Wrapped not shown winding rod or winding tube and secured thereto end. By pulling out and unwinding is the width of the cover 1 variable to the width of the gap 4 customizable, whereby by the unwinding and passing the forced operation 12 the housing 5 removed portion of the respective support element 9 in the second stable position 10 is spent in the free-bearing function of the support element 9 , ie the bistable spring band 9 , is guaranteed.

In 5 is a frontal view of a side portion of the housing 5 the cover 1 with the slot 6 in the case 5 shown by the support element 9 including textile surface element 8th out of the case 5 led out. In the area behind the slot opening is the forced operation 12 recognizable, which the convex shape for the support element 9 defined and when passing the support member 9 this the arched, the second stable position 10 imposes corresponding cross section, so that this is the surface element 9 can take over a free-bearing function, without it next to the attachment to the housing 5 no additional supports of the surface element 8th and the one or more support elements 9 requirement. Possible is the front side of the surface element 8th or the respective support element 9 Provide mounting arrangements, which with corresponding mating fastening arrangements on the rear seat back 3 interact. For example, hooks and eyes, Velcro connections or snap-in connections can be provided, which of course should only be exemplary.

6 shows a view of the side area 5 , where the arrangement of the cover 1 behind the rear seat back 3 the vehicle is recognizable. For easier removal of the in the case 5 in the wound state surface element 8th including the support elements 9 is a handle 7 , For example, provided in the embodiment as a bridge. The jetty 7 has such a dimension that it is easily accessible, and virtually forms a winding barrier, so that the surface element 8th together with the support elements 9 only up to a predetermined amount in the housing 5 is rollable, and easy to roll out again. The handle 7 can also be designed as an engagement opening, wherein a bump can be provided as a winding barrier, wherein the winding mechanism can be designed only for a certain Einrollänge.
