Description

The present invention relates to a cover for closing an opening formed in a wall, in particular a section of the body or the paneling of a motor vehicle.

A cover for closing an opening is from the script EP 1 331 138 A2 known, in which the wall on its inside in the opening area has a support contour for the cover, which makes it possible to insert the cover inserted into the opening about a tilt axis between a closed position, in which the cover closes the opening, and a tilted position, in the cover is tilted with respect to its closed position and can be removed from the wall of the opening on the outside and / or inserted into the opening. To attach the cover, there is a tooth on the cover that projects laterally beyond the cover and engages behind an edge of the opening in the closed position, as well as teeth that protrude from the back of the cover and are locked in a locking contour that is firmly connected to the wall , intended. In addition, fixed guide contours and lateral guide elements are provided which make it possible to assume a predetermined relative position between the cover and the wall during pivoting and in the closed position.

The construction known from this document enables safe closing, simple opening and exposing the opening, for example in a bumper trim, in order to achieve a towing device arranged behind the opening.

In order to enable such closing and opening by means of pivoting between the closed and the tilted positions, the cover of the known configuration lies only with a partial area of its circumference on a support section formed along the edge of the opening, this partial area generally only on one Side is formed with respect to the tilt axis. The result of this is that the cover is located in the other assigned partial area, which corresponds to the other side with respect to the tilt axis, without such support being provided by a support area, and being held exclusively by the locking and holding elements provided in each case. The problem can therefore arise that the cover is not held flush with the wall, but rather with the cover projecting beyond the wall plane or being deepened, for example due to tolerances caused by the production and / or the material and / or the Flexibility and the play of the provided locking and holding elements, so that an optically and / or haptically unattractive effect is created. It is also possible that the cover at this point causes rattling due to inadequate fastening, which can reduce the quality of the product effect. This problem occurs in particular when the tilting axis cannot be arranged for constructional and / or technical reasons such that only a small area of the cover rests without support of the support area, for example by the tilting axis in this area as close as possible to the edge of the cover is positioned, but the tilt axis must be arranged for design and / or technical reasons, for example in the middle of the cover or even in a direction away from the free-swinging end of the cover.

The font DE 102012216792 A1 discloses a cover for closing a recess arranged on a component of a body trim. The cover has lower projections on its lower outer edge. The lower protrusions have rounded protrusions that are shaped so that the protrusions of the cover, when inserted into the corresponding through openings formed in the recess, lock the edges of the openings.

The purpose of the present invention is therefore to provide a cover for closing an opening formed in a wall, in particular a section of the body or the paneling of a motor vehicle, by means of which a possible impairment of the aesthetic effect is better avoided.

According to a first aspect, a cover is provided for closing an opening formed in a wall, in particular a section of the body or trim of a motor vehicle, the cover, when it engages in the opening, about a tilt axis between a closed position in which the Cover closes the opening, and a tilted position in which the cover is tilted with respect to its closed position, pivoted and removed from the opening and / or can be inserted into the opening. The cover comprises at least one clamp element that protrudes from the back of the cover. The clamp element further comprises at least one arm, a contact surface being formed on an upper section of the at least one arm. The clamp element is designed such that in the closed position it is preferably arranged on or attached to the wall Interacting bracket receiving element, wherein at least one support edge is formed on the bracket receiving element. If the cover is in the closed position, the contact surface formed on the at least one arm rests against a contact edge which is assigned to the contact surface and is formed on the clamp receiving element such that the clamp element exerts a force directed in the vertical direction of the rear of the cover.

Thus, a clamp element is provided which generates a pretension of the cover in the vertical direction by pressing the two contact surfaces which are slightly inclined with respect to the vertical and directed in opposite directions against the corresponding contact edges of the clamp receiving element in the closed position of the cover. As a result, the cover is pressed slightly outwards at the position of the clamp element and the cover can thus be held in a flush position with respect to the wall without an indentation which can be perceived visually or haptically.

In addition, when the cover is correctly positioned when the cover engages in the opening, the clamp element simultaneously provides support and can also ensure as a guide when the cover is pivoted between the tilted and closed positions.

The cover preferably further comprises at least one tab arranged on the back of the cover, which tab is intended to come into contact with an edge of the opening and with a back of the wall on the back in the closed position. The at least one tab and the clip element are arranged in the same area with respect to the tilt axis, the force exerted by the clip element and directed in the vertical direction of the back of the cover acting on the at least one tab with a pretension so that it is pressed against the back of the wall becomes.

This leads to the fact that in the closed position the tab (s) come into contact with pressure against the back of the wall depending on the pretension generated by the clamp element. The clip element and the tab or the tabs act together so that the cover is held in the closed position with respect to the wall in a well-defined position. As a result, the cover can be held in a flush position with respect to the wall without an optically or haptically perceptible depression or elevation being produced.

It can also be provided that the cover comprises two or more tabs, for example 3, 4, 5, 6 or more tabs, the two or more tabs and the clamp element being arranged in the same area with respect to the tilt axis. The two or more tabs are particularly preferably arranged on both sides of the clamp element.

In particular, the two or more tabs and the clip element can cooperate in such a way that they fix the cover with respect to the wall at three points. In this way, it is particularly safe to prevent the cover from protruding beyond the wall level or from being pressed in under or behind the wall level.

Preferably, the wall in the region of the opening can comprise a support section, the support section and the clamp element being arranged in opposite regions with respect to the tilt axis and, when the cover is in the closed position, that exerted by the clamp element in the vertical direction of the rear of the cover Force the cover in the direction of the support portion with a bias.

In other words, the back of the cover can be acted upon by the force generated by the clamp element in the vertical direction in such a way that, in view of a rotation about the tilt axis, the other end of the cover, which is remote from the clamp element, is pressed in the direction of the bearing surface.

The cover preferably further comprises at least one latching hook, which is arranged on the back of the cover and is provided for latching on an associated latching element, the latching hook and the clamp element being arranged in opposite regions with respect to the tilt axis. If the cover is in the closed position, the force exerted by the clamp element and directed in the vertical direction of the rear of the cover acts on the cover with a torque about the tilting axis, which has the same direction of rotation as a torque about the tilting axis with which the latching hook engages Cover has applied.

It can preferably also be provided that along a connecting line between the latching hook and the clip element, a distance between the clip element and the tilting axis is greater than or equal to a distance between the latching hook and the tilting axis along the connecting line, in particular 1.0 times larger, preferably 1.3 times larger, more preferably 1.5 times larger.

Even in the case of elongated covers, in particular covers which can extend far from the tilting axis in the direction of the side of the clamp element, the cover can be held on the wall by the pretension generated by the clamp element without protruding or indenting. This allows greater freedom of design when designing a cover without impairing the visual or haptic effect.

The clip receiving element is preferably arranged on the wall or fastened to the wall.

When the cover is pivoted from the closed position, the clip element is preferably released from the clip receiving element, so that the cover can be removed from the opening.

The clamp element preferably comprises at least two arms, a contact surface being formed on the upper section of each arm.

It can preferably also be provided that the clip receiving element comprises a cutout for receiving at least a portion of the clip element, at least two contact edges being formed in the cutout and, when the cover is in the closed position, the contact surfaces formed on the at least two arms each bear against a contact surface which is assigned to the contact edges formed on the clip receiving element.

It can preferably also be provided that the cutout of the clamp receiving element is U-shaped and / or that the support edges comprise at least two support edges which are formed on two opposite sides of the cutout.

Even more preferably, it can be provided that the clip receiving element further comprises a support edge which extends along the recess and is formed to extend between the two support edges formed on opposite sides of the recess, with one side surface when the cover is in the closed position each of the two arms comes into contact with the support edge extending along the recess.

The arms can preferably be formed opposite one another and each bent away from one another.

The contact surfaces of the clamp element can each be formed on the outside of the arm. Alternatively, the contact surfaces can each be formed on the inside of the arm.

In particular, the clip element can have the shape of an O- or Ω-shaped clip, the clip element preferably being opened upward in the direction pointing away from the cover.

The clamp element can also comprise a web which connects the arms of the clamp element to one another and in particular connects the arms to one another at the foot sections of the respective arms. The foot sections and the web assigned to the rear of the cover preferably delimit an opening.

The cover preferably has a three-dimensional shape. In particular, the cover can comprise a first cover section and a second cover section, the clip element being formed on the second cover section. The first cover section and the second cover section may at least partially not be formed in the same plane. Alternatively or additionally, the second cover section can have the shape of a curved plate. Alternatively or additionally, the tilt axis can be formed in the region of the first cover section.

In the case of three-dimensionally designed covers, which are intended, for example, for attachment to a bumper trim in the region of a bend, on a construction edge or the like and are therefore produced with a three-dimensional shape provided for this purpose, the cover can be applied without protrusion or indentation by the pretension applied by the clamp element the wall are held. As already mentioned, this allows greater design freedom when designing a cover without impairing the visual or haptic effect.

In a three-dimensional shape of this type of cover, the first cover section and the second cover section can adjoin one another along a bending line. In this case, the bending line can preferably be spaced from the tilt axis by a distance of in particular at least 3 mm, more preferably at least 5 mm and particularly preferably at least 10 mm.

This type of configuration means that the clamp element does not extend perpendicular to a fictitious connecting line with respect to the tilt axis, but rather is inclined with respect to it, so that the contact surfaces of the clamp element are in particular closer to the tilt axis than the foot sections of the clamp element. In this way, they can be more easily separated from the clamp receiving element when the cover is pivoted from the closed position into the tilted position.

Preferably, the clip receiving member may further include a support edge extending along the recess and extending between the two support edges formed on opposite sides of the recess, with one side surface of each of the two arms when the cover is in the closed position each comes into contact with the support edge extending along the recess.

With this type of configuration, the clamp element can also generate an additional pretension in a different direction parallel to the rear of the cover and thus enable a further improved centering of the cover and / or render an additional latching hook, which is otherwise required, useless.

For example, it can be provided that the clamp element is arranged with respect to the tilt axis in the region of the cover which is subjected to a compressive force on the front in order to pivot the cover from the closed position into the tilted position.

It can preferably also be provided that a direction of the lateral extension of the clamp element, which extends over the two opposite arms, defines an angle with respect to the tilting axis which is in the range from −20 ° to + 20 °, preferably in the range of −15 ° to + 15 °, more preferably in the range from -10 ° to + 10 °, particularly preferably in the range from -5 ° to + 5 °.

The design means by which the tilt axis is defined and defined often make it possible to simultaneously achieve very good positioning in the plane of the cover in the direction perpendicular to the tilt axis. In the direction parallel to the tilting axis of the cover in the plane, however, there is generally a certain play which is necessary in view of tolerances based on the manufacture and / or the material. If the clamp element leads to a centering and fixing of the cover in this direction parallel to the tilt axis, an effective handling of these tolerances is possible. It is therefore particularly provided that the lateral extent of the clamp element, insofar as it is a direction running parallel to the plane of the cover through the two arms, runs approximately parallel to the tilt axis. Due to the flexibility inherent in the arms, especially in the level of the contact surfaces, and the possible bevels, it is not absolutely necessary that the lateral extension of the clamp element and the tilt axis run exactly parallel, and it is also possible to have an angular deviation in the range mentioned To provide, for example, to meet other design requirements, at the same time a sufficiently good centering of the cover is achieved, wherein a simple tilting of the cover from the closed to the tilted position with subsequent removal of the cover from the opening remains possible.

The clip element can be formed perpendicular to the back of the cover. Alternatively, the clip element can be inclined at an angle with respect to a normal of the rear of the cover, so that the clip element is inclined with respect to the clip receiving element, the angle in the range between 5 ° and 45 °, preferably in the range between 10 ° and 33 ° and particularly is preferably in the range between 20 ° and 30 °.

If the clamp element is formed perpendicular to the back of the cover, the injection mold used to manufacture the cover can be made simpler, since fewer undercuts have to be made. Conversely, a clamp element that is inclined with respect to the vertical would require a higher production outlay, but would be advantageous in view of the even simpler tilting from the closed position into the tilted position and the even easier pulling out of the clamp element from the clamp receiving element.

The cover is preferably essentially complementary to the opening and, in the closed position, covers practically the entire opening.

Preferably, the wall in the area of the opening comprises a section for supporting the cover.

On the back of the cover, it is preferably possible to also form two tabs that define the tilt axis.

The front of the cover is preferably designed such that in the closed position it forms an integral part of the wall.

The wall can in particular be formed by a bumper covering of a motor vehicle, the opening allowing access to a towing device, for example a towing eye thread or a towing hook, of the motor vehicle through the bumper covering.

According to a second aspect, a system of cover and wall is provided, in particular a section of the body or paneling of a motor vehicle, that a cover as disclosed in the present document, in particular as described above; and a wall, in which the opening is formed and which can be closed by the cover, wherein the wall has the at least one clip receiving element and / or the at least one clip receiving element is fastened to or with the wall.

In the area of the opening, the wall can include the support section for the cover.

In the system of cover and wall, two receiving areas can preferably be formed in the support section for receiving the pins in order to define the tilt axis.

According to a third aspect, a motor vehicle is provided which comprises a system of cover and wall as described above.

Detailed description

A preferred embodiment is based on the 1 to 3rd described. In 1 becomes a cover 10th schematically in one of the Back of the cover 10th perspective view created here. In 2nd schematically becomes a wall 50 in one from the back of the wall 50 forth perspective view shown, with an opening in the wall 40 is formed in the cover 10th to intervene. 3rd shows an arrangement of the cover 10th and the wall 50 , with the cover 10th into the opening 40 the wall 50 intervenes.

The wall 50 can be formed for example by a body or panel section of a motor vehicle. Preferably the wall 50 formed by a bumper covering of a motor vehicle, in particular a passenger car, the opening 40 should preferably serve through the bumper trim (wall 50 ) to enable access to a towing device, not shown here, such as a towing eye or a towing hook.

The cover closes in the closed position 10th the opening 40 . In the tilted position, the cover can 10th but from the opening 40 be removed or into the opening 40 be used. For this purpose the cover points 10th a shape that is substantially complementary to that of the opening 40 is so the cover 10th in the closed position of the cover 10th practically the entire opening 40 covers. A front 18th the cover 10th is functionally designed so that in the closed position it is an integral part of the wall 50 forms, ie the front 18th the cover 10th is the outer contour of the wall 50 customized. In the preferred embodiment, in which the wall 50 is formed by a bumper cover, the outside of the bumper cover (wall 50 ) be covered with a varnish. The front preferably has 18th the cover 10th also such a paint on, so that coverage 10th in the closed position also visually and haptically with the wall 50 forms a unit.

The wall 50 includes in the area of the opening 40 a support section 51 for the cover 10th . This support section 51 is functionally designed or designed to fit the edge of the opening 40 at least partially surrounds and into the opening 40 inserted cover 10th about a tilt axis 15 between one in 3rd shown closed position and a tilted position can be pivoted. For example, the support section extends 51 as from the embodiment of 1 to 3rd removable, with respect to the tilt axis 15 only on one side. The tilt axis 15 extends parallel to the back of the cover in this embodiment 10th . The support section 51 can be a section of the wall 50 form that in the opening 40 extends and if the cover 10th in the closed position with the cover 10th comes into contact on the back. The support section 51 can be used in some embodiments as a flat carrier of the cover 10th serve. In other embodiments, a flat carrier of the cover cannot 10th be present and it is possible that at least one (not shown) support point on the support section 51 is formed so that the cover 10th rests on the support point in the closed position. In still other embodiments, the support section 51 completely missing or the support section 51 can be provided without the cover 10th in the closed position on the support section 51 lies on.

The backside 19th the cover 10th includes a tab 12th that side over an edge of the cover 10th protrudes. In the in 3rd shown closed position comes the tab 12th on the back with the edge of the opening 40 in contact and lies on the back of the wall 50 on. The representation with a single tab 12th is not a limitation and it is also possible to use the tab 12th elsewhere on the cover 10th to provide and / or several tabs 12th , such as 2, 3, 4, 5, 6 or more tabs 12th to provide.

On the back side 19th covers the cover 10th in this embodiment also two latching hooks 11 . The locking hooks snap in the closed position 11 with corresponding locking elements 53 a, which are integrally formed with the wall. The locking hooks 11 are designed to be flexible so that they can be disengaged without being destroyed. As shown, the locking elements can thus preferably be provided 53 on a back of the support section 51 near a recess 52 are formed in the support section 51 provided and for receiving the locking hook 11 is trained. In other embodiments, more than two locking hooks can be used 11 be provided or it can also be a single latching hook 11 be provided.

The backside 19th the cover 10th also includes two pins 14 that are intended for inclusion in the two corresponding, in the support section 51 trained reception areas 54 are arranged and designed, this being done so that the tilt axis 15 is defined around which the cover 10th can be tilted between the closed position and the tilted position.

In the in 3rd The closed position shown is the cover 10th arranged so that they are in the opening themselves 40 stops and on the wall 50 is fixed. Around the cover 10th from their Bring the closed position into its tilted position is in the cover 10th by the user, for example in the direction of the arrow 30th from the front 18th out with a finger on the cover 10th presses in the direction of the arrow 30th a pushing force on the front 18th the cover 10th in one of the locking hooks 11 with respect to the tilt axis 15 opposite area generated. This pressure force 30th is about the in the recording areas 54 of the support section 51 held and attached cones 14 that the tilt axis 15 define, converted into a traction with which the locking hook 11 is applied. If a sufficiently high pressure is exerted, the locking hooks snap into place 11 from their locking element 53 and come off. The cover 10th can thus in its tilted position about the tilt axis 15 be pivoted. In the tilted position, the cover can 10th out of the opening 40 can now be removed.

To a defined position of the cover 10th in the opening 40 To ensure, one or more side guide pieces can also be on the back 19th the cover 10th be trained. A side guide piece 13 is shown for example. You can also cover the other parts 10th and / or the wall 50 corresponding lateral guide pieces can be formed.

In addition, the cover 10th In order to prevent any loss, a gripping element (not shown), as is known, for example, from the document EP 3 342 687 A1 is known to include.

The cover 10th is preferably manufactured in the form of a one-piece or one-piece component, in particular in the form of an injection molding component. It can be used in the manufacture of the cover 10th may be possible on the front 18th the cover 10th to apply a paint.

As especially in the 1 and 3rd shown includes the cover 10th in this embodiment a clamp element 20 that from the back 19th the cover 10th protrudes. The bracket element 20 includes two opposing arms (see 4th , 5 and 7 ), which are each bent away from each other so that they have the shape of an open "O" or an open "Ω". The two arms 21 each comprise a contact surface at their upper section 23 , wherein the contact surfaces in opposite directions (lateral direction of the clamp element 20 or direction of the X axis in the figures) are directed outward and move away from each other. The contact areas 23 extend from the top of each arm 21 up to a respective thigh edge 28 . The bracket element 20 points at the level of the thigh margins 28 the largest width, ie the bracket element 20 at this point points to the side 70 the greatest extension. After the thigh margin 28 the clamp element tapers 20 along each of the arms 21 trained backs 29 again to finally leak with the foot sections. In other words, in this embodiment they are on the outside of the arms 21 arranged contact surfaces 23 formed so that the bracket element 20 from the thigh edges 28 to the top of the arms 21 increasingly tapered in width (lateral extension 70 ). The poor 21 are at the height of their foot sections 22 through a footbridge 25th interconnected so that between the web 25th and the back 19th an opening in the cover 26 consists.

In this embodiment, a clamp receiving element is fixedly connected to the wall 60 (please refer 2nd and 3rd ) as a complementary element to the bracket element 20 intended. As especially in 6 shown includes the clip receiving element 60 a U-shaped recess 61 , the side of two contact edges 62 is limited and defined. This recess 61 is for receiving the clamp element 20 provided when the cover 10th , especially in the 3rd and 7 shown in the closed position. Here is the bracket element 20 in the closed position not in the sense on the clip receiving element 60 snapped that clip element 20 the clip receiving element 60 encloses or is otherwise engaged in this. In the closed position, however, the clamp element 20 be considered as an element which is the staple receiving element 60 pressurized, whereupon the clip member 20 with a vertical relative to the back 19th the cover 10th directed force on the cover 10th is present.

At the recess 61 can advantageously also have a longitudinal support edge 64 be formed between the two contact edges 62 extends and if the cover 10th is in the closed position, the clip element 10th with the side faces 24th the poor 21 on the contact edge 64 support, thereby in the plane of the cover perpendicular to the tilt axis 10th in another direction (the Y direction of the figures) a bias of the cover 10th to evoke.

The poor 21 of the bracket element 20 can be designed with a substantially rectangular cross section (in the figures a cross section in the X Y plane), preferably with rounded corners, so that the arms 21 on the side of the bracket receiving element 60 and on the the bracket receiving element 60 opposite side each have the same thickness. However, it is preferable that the arms 21 , as in 5 shown on the the bracket receiving element 60 opposite side are reinforced so that the arms 21 have approximately the shape of an L in a cross section in the XY plane. In other words, the arms are 21 on the the bracket receiving element 60 opposite side reinforced with additional material, which means better absorption and better derivation of the clamp element 20 acting forces can be ensured, so that undesirable plastic deformation of the bracket element 20 can be avoided. At the same time, this configuration leads to the contact surfaces 23 opposite back of the arms 21 to create a recess 27 extending towards the bracket receiving element 60 opens what is particularly in the upper area where the contact surfaces 23 are designed to give flexibility such that the contact surfaces 23 especially in view of the design tolerances better to the corresponding shape and orientation of the support edges 62 can be customized.

When swiveling the cover 10th is from the closed position to the tilted position by applying a compressive force in the direction of the arrow 30th to the front 18th the cover 10th the cover 10th from the closed position (in 8th : dashed lines) in the tilted position (in 8th : solid lines) and the bracket element 20 due to the rotating tilting movement out of the recess 61 of the clip receiving element 60 pushed out so that the clamp element 20 is released and the cover 10th well, as in 8th shown, can be removed. The bracket element 20 then with respect to the clip receiving member 60 moved, the contact edges 62 yourself over the contact areas 23 Extend until they are over the thigh edges 28 be performed. After the support edges 62 the thighs 28 have touched and there the clip element 20 themselves along the backs 29 the clamp element becomes increasingly tapered with regard to its lateral extension 20 from the clip receiving element 60 "Snaps" and is released, so the cover 10th can now be removed.

Although a preferred embodiment has been described above, the disclosure is not limited by the foregoing description. In addition, the person skilled in the art can see that various additions or changes are possible.

For example, it is not necessary that the clamp element 20 perpendicular to the back 19th the cover 10th extends, but instead, as in 9 shown, be provided that the clamp element 20 at a certain angle β regarding the normal of the back 19th the cover 10th is inclined, the clamp element 20 preferably in the direction of the clip receiving element 60 is inclined. Depending on the shape of the clip receiving element 60 and / or other adjoining sections, such an inclined configuration can be easier to pull out the clamp element 20 out of the recess 61 to lead. The angle β can be, for example, in a range between 5 ° and 45 °. The angle β is preferably in the range between 10 ° and 33 ° and particularly preferably in the range between 20 ° and 30 °.

In addition, the bracket element 20 also, as in the view of the clip element in plan view 10th shown with respect to the tilt axis 15 be aligned. Thus, a direction of lateral extension of the bracket member 20 by the two opposite arms 21 runs and the in 10th through the line 70 is represented by an angle α with respect to the tilt axis 15 or regarding one in 10th parallel shown 15 ' opposite the tilt axis 15 be turned. The angle α can assume a value in the range from -20 ° to + 20 °, preferably in the range from -15 ° to + 15 °, more preferably in the range from -10 ° to + 10 ° and particularly preferably in the range from -5 ° to + 5 °.

Furthermore, it is possible to provide that the clamp element 20 not open, but in the form of a closed O or in the form of an (open or closed) Ω.

As described in the embodiment described above and in particular in the 1 to 3rd shown, the cover 10th in the form of an essentially plate-shaped cover 10th be carried out. However, this is not restrictive and it is also possible to cover it 10th , such as in the 12A and 12B shown to give a three-dimensional shape. 12A schematically represents an oblique top view of the back of a cover 10th according to another embodiment, and 12B represents schematically a cross section through the cover 10th out 12A along a connecting line between the locking hook 11 and the bracket element 20 represents.

As in 12A and 12B shown is the cover 10th of this exemplary embodiment is carried out in a form in which a first plate-shaped cover section 10a and a second plate-shaped cover section 10b along a bending line 10c adjoin each other, the first cover portion 10a and the second cover section 10b are inclined at a certain angle to one another so that they do not extend in a common plane. The bending line 10c can with the tilt axis 15 collapse. However, it is preferred that the bend line 10c from the tilt axis 15 at a distance d3 is spaced, the bend line 10c towards the side of the bracket element 20 is offset. Consequently, the tilt axis 15 alone over the first cover section 10a extend. The distance d3 is preferably along the the locking hook 11 and the bracket element 20 connecting connecting line measured. Such a configuration causes the clamp element 10th not perpendicular to a fictitious connecting line with respect to the tilt axis 15 extends, but is inclined with respect to this connecting line, so that the contact surfaces 23 of the bracket element 20 especially closer to the tilt axis 15 lie than the foot sections 22 of the bracket element. In this way, they can be swiveled when the cover is swiveled 10th from the closed position to the tilted position more easily from the clamp receiving element 60 separate.

As especially in 12B shown is the distance d2 between the bracket element 20 and the tilt axis 15 moreover, the same size as or greater than the distance d1 between the locking element 11 and the tilt axis and can in particular be 1.0 times larger, preferably 1.3 times larger and more preferably 1.5 times larger. Alternatively or additionally, a maximum extension of the second cover section can 10b , ie the maximum distance between one on the edge of the second cover section 10b located point and the tilt axis 15 , greater than or equal to a maximum extent of the first cover section, ie the maximum distance between one on the edge of the first cover section 10a located point and the tilt axis 15 , and can in particular be 1.0 times larger, preferably 1.3 times larger and more preferably 1.5 times larger.

However, there is no restriction to the three-dimensional shape, for example in the 12A and 12B is shown, and it is also possible to cover 10th to give different and / or complex shapes. For example, it is possible for the first cover section 10a and / or the second cover section 10b not give the shape of a flat plate, but the shape of a curved plate, making three corners of the cover 10th (For example, the two corners of the first cover section 10a and a corner of the second cover portion 10b ), for example, are in the same plane, while the other corners of the cover 10th with respect to this plane, in particular with respect to the inside of the wall, such as that of a bumper, for example. Curved, folded or other shapes are also possible.

Although it was described in the above embodiments that the contact surfaces 23 each on the outside of the arms 21 are formed, the invention is not limited to this and it is also possible to provide that the contact surfaces 23 , as in 11 schematically shown, each on an inside of the upper portion of each arm 21 are trained. The contact areas 23 are also slightly inclined with respect to the vertical in opposite directions in this embodiment, so that the effect of a prestress in the vertical direction (Z-axis direction) can also be achieved in this embodiment. How out 11 you can see the outside and the inside of the arms 21 of the bracket element 20 regarding the in 1 to 10th shown bracket element inverted in the sense that the edge of the leg 28 the smallest (local) width of the bracket element 20 defined, the contact areas 23 are designed so that the distance between the contact surfaces 23 from the thigh edge 28 to the top of the arm 21 is getting bigger. Consequently, it is also possible to use the clip receiving element 60 in another way, for example, as also schematically in 11 shown, in the form of a web with two laterally arranged, outwardly projecting contact edges 62 to execute.

It is also possible to have more than one bracket element 20 , such as 2, 3, 4, 5 or 6 or more clip elements.

In addition, it is also possible to use the clip receiving element 60 perform in other forms. The bracket element 60 can thus be carried out in any suitable form that it in the closed position of the contact surface 23 or the two or more contact surfaces 23 of the bracket element 20 suitable shape allows, on one or more corresponding support edges 62 to lie on, each of the contact surface (s) 23 are assigned, and it allows the bracket element 20 when swiveling the cover 10th from the closed position to the tilted position from the clip receiving element 60 to solve. It is thus also possible, for example, to construct the clamp element 20 and a corresponding clip receiving element 60 to realize how in the in the 13 to 17th shown embodiment is used.

13 represents one from the back 19th the cover 10th Perspective view of the cover 10th according to a further embodiment. The clamp element 20 is in this embodiment with only one arm 21 executed, being at the upper end portion of the arm 21 another one Contact area 23 is trained (see 15 ). In this embodiment, the bracket element 20 formed so that the "apex of the legs" essentially in the direction of the edge of the wall 50 shows. In this embodiment, too, there are two tabs 12th provided on both sides of the bracket member 20 are arranged.

14 represents a perspective view of the back of an opening 40 the wall 50 into which the cover is made 13 to intervene. On the wall 50 is in turn a clip receiving element 60 formed, which is designed so that it with the clip element 20 the cover 13 cooperates.

The bracket element 20 the cover 10th out 13 is in 15 presented in more detail. As in 15 shown is the bracket element 20 this embodiment with only one arm 21 executed, at the upper end of the contact surface 23 is trained. The only arm 21 of the bracket element 20 This embodiment can be substantially the same or similar to one of the arms 21 of the bracket element 20 from the 4th and 6 be executed and consequently a foot section 22 , a thigh edge 28 which is the contact area 23 limited on the side opposite to the upper end section, and a rear side 29 that are between the edge of the thigh 28 and the foot section 22 extends include. Around the bracket element 20 to give a higher rigidity and / or to the on the clamp element 20 absorbing and dissipating forces better, it is also possible to use a web 22 ' to provide the at the foot section 22 is applied and runs perpendicular to this.

16 shows that to the bracket element 20 out 15 associated clip receiving element 60 . As in 16 shown, the clip receiving element 60 in one piece with the material of the wall 50 be formed, the clamp receiving element 60 from the edge of the wall 50 , ie at the edge of the opening 40 , extends perpendicular to this, after bending again in a direction parallel to the wall 50 up over the opening 40 to extend out. The contact edge is in the area of the end section of the clip receiving element 62 formed, which can be designed here in the form of an inclined surface, the inclination of this surface preferably substantially corresponding to the inclination of the contact surface 23 of the bracket element 20 can be executed.

The interaction of the bracket element 20 with the clip receiving element 60 this embodiment in the closed position is in 17th shown. In the closed position shown, in which the cover 10th in the opening 40 is inserted, the contact surface 23 of the bracket element 20 on the contact edge 62 of the clip receiving element 60 on. Due to the inclination of the contact surface 23 and the contact edge 62 therefore become one in to the back of the cover 10th parallel force (in the Y-axis direction) and one in towards the back of the cover 10th force directed in the vertical direction (in the direction of the negative Z axis). These forces are created using the foot section 22 , and if necessary by means of the web 22 ' derived and in the cover 10th initiated. The force exerted in the parallel direction is, for example, by the locking elements on the locking elements 53 restrained forces and / or by possibly provided lateral guide pieces 13 compensated. The one in the vertical direction to the back 19th the cover 10th Exerted force in turn, as described above, causes the cover 10th can be easily pushed outwards, which in turn causes the tab 12th in firm contact against the back of the wall 50 can be pressed and thus the cover can be held in a well-defined position without protruding or indenting. It can therefore be seen that the two tabs 12th and the bracket element 20 a 3-point fixation of the cover section in question on the wall 50 can create.
