Description

The invention relates to a holding device for a motor vehicle.

Holding devices are used in various designs within motor vehicles. The holding bodies of the holding device can be designed, for example, as device carriers to which electronic devices such as displays or the like are attached.

When the holding device is designed as a device carrier, functional elements are mounted on the holding body to reinforce it and to provide mounting and fastening points, which are fixed to the holding body by means of screws.

This creates a high risk of damage to the parts to be installed. In addition, assembly is difficult and time-consuming due to the often difficult accessibility.

An object of an embodiment of the invention is to propose a holding device of a motor vehicle which can be mounted in a simplified manner.

This object is achieved by a holding device for a motor vehicle with a holding body to which a consumer or a component of the motor vehicle can be secured, with a planar functional element which is secured to the holding body in a joined arrangement, with at least one guide unit which comprises at least one first projection extending in a first joining direction and a stop section extending transversely to the first joining direction on the functional element or on the holding body, and which comprises at least one recess on the holding body or on the functional element and an edge section surrounding the recess, wherein the functional element and the holding body can be arranged in a first stop position in which the first projection is inserted into the recess, in which the stop section rests on the edge section and in which the first projection rests in contact with one end of the recess, and wherein the functional element can be folded at least in the first stop position about a rotation or pivot axis running transversely to the first joining direction and can be transferred to a second stop position in which the functional element rests in contact with the holding body with an end opposite the guide unit, with at least one joining unit which is arranged in the second stop position at the end of the functional element or the holding body opposite the guide unit, which comprises a second projection on the functional element or on the holding body which extends parallel to the rotation or pivot axis and which comprises a receptacle in or on the holding body or functional element, wherein the functional element is disengaged from the receptacle when the functional element is arranged simultaneously in the first stop position and in the second stop position and can be moved by transferring the functional element along a second joining direction running parallel to the rotation or pivot axis into a locking position in which the second projection engages in the receptacle and fixes the functional element against movement about the rotation or pivot axis, and with at least one locking unit which comprises a rear gripping means on the holding body or on the functional element and a rear gripping section on the functional element or on the holding body, wherein the rear gripping means in the locking position engages behind the rear gripping section counter to the second joining direction.

Because the holding device comprises a guide unit, a joining unit and a locking unit, the functional element and the holding body can be joined together without tools. This reduces the risk of damage to the individual parts and components.

The guide unit allows the functional element and the holding body to be pre-assembled and joined together manually by arranging them first in the first stop position, then by transferring them to the second stop position and then by transferring them from the second stop position to the locking position.

The use of the word "or" is used in the original sense of the word. This means, for example, that if the projection of the guide unit is arranged on the functional element, the recess is arranged on the holding body in the option mentioned below and vice versa.

In order to ensure in a simple manner that the projection of the guide unit can perform a movement about the rotation or pivot axis in the recess of the guide unit, it proves to be advantageous if the functional element or holding body comprising the at least one recess of the guide unit comprises a section with an L-shaped cross-section, in the bending region of which the recess is arranged and/or if the recess comprises a length extending transversely to the first joining direction, which enables the first projection to move transversely to the first joining direction from the first stop position into the locking position.

This makes it easy for the functional element to form an angle of up to 90° with the holding body when joining along the first joining direction and to be pivoted by 90° when transferred to the second stop position with the projection arranged in the recess, so that the functional element and the holding body run essentially parallel to one another and, if necessary, lie flat against one another.

Because the recess comprises a length extending transversely to the first joining direction, which enables the projection to move transversely to the first joining direction from the first stop position into the locking position, the holding body and the functional element are fixed to one another so that they can move relative to one another during the entire joining process.

Furthermore, it is conceivable that the recess comprises a width extending transversely to the first joining direction that is greater than the width of the projection transversely to the first joining direction. This facilitates a rotational or pivoting movement about the rotational or pivoting axis.

The stop section can continue the projection transversely to the joining direction. In this case, it can project beyond the recess in terms of the longitudinal direction of the recess and/or in terms of the width direction of the recess.

In order to make the holding device compact, it proves to be advantageous if the joining unit on the holding body or functional element comprising the second projection comprises an opening which extends transversely to the second joining direction, in particular a continuous opening, into which the second projection projects and in which the receptacle arranged on the functional element or on the holding body is arranged in the second stop position.

Because the joining unit comprises a continuous opening in the holding body or in the functional element, into which the second projection projects and in which the receptacle arranged on the functional element or on the holding body can be arranged in the second stop position, the second projection can be designed to continue the functional element or the holding body. In this case, no offset of the second projection is necessary. This enables a compact design of the holding device in the joined arrangement.

In a further development of the holding device, it is provided that the guide unit comprises at least one rib-like locking means on the holding body and/or on the functional element, which in an intermediate arrangement of functional element and holding body outside the first stop position rests on the functional element or on the holding body when the functional element is transferred by folding about the rotation or pivot axis into the second stop position before reaching the second stop position and blocks further movement and which in an intermediate arrangement of functional element and holding body in the first stop position is arranged without overlapping with a wall area of the functional element or holding body and movement into the second stop position is released.

Because the guide unit comprises a rib-like locking means on the holding body and/or on the functional element, by means of which transfer of the functional element into the second stop position is blocked if the functional element is not arranged in the first stop position, a user who manually joins the functional element and the holding body together can be made to detect that the functional element and the holding body are not correctly arranged relative to one another.

This can prevent damage to components of the holding device and ensure correct and safe joining of the holding body and functional element.

Because the locking means only releases the transfer to the second stop position, i.e. does not block it, when the functional element and the holding body are arranged in the first stop position, it can be ensured that the second projection is correctly placed in front of the receptacle before the functional element is transferred to the locking position.

Because the locking means is designed like ribs, the transfer movement is only blocked after a transfer movement has already been carried out. In embodiments of the holding device, the functional element can be moved by up to 50° around the rotation or swivel axis before further movement is blocked by the locking means.

In a further development of the latter embodiment, it proves to be advantageous if the locking means is arranged on a side of the receptacle arranged on the holding body or on the functional element facing the functional element or the holding body and/or if the locking means protrudes into the opening, in particular the through opening, in the second stop position and in the locking position.

If the locking means is on a surface facing the functional element or the holding body The holding device can be made compact if the locking means is arranged on the side of the receptacle arranged on the holding body or on the functional element. In addition, this makes it easy for the locking means to reach through when the functional element is transferred from the first stop position to the second stop position. In this case, the locking means reaches through the opening in the wall area of the functional element or the holding body.

The locking unit's engagement means secures the functional element and the holding body against relative movement in the opposite direction to the second joining direction. In order to reduce the play between the holding body and the functional element in the locking position, one embodiment of the holding device provides that the locking unit comprises at least one rail-like clamping means which is arranged on the holding body and/or on the functional element and which comprises a ramp-like section, by means of which a distance between the holding body and the functional element is increased when the functional element is transferred into the locking position and the first projection is clamped against the edge of the recess and the second projection is clamped against the receptacle.

By providing a rail-like clamping device, the holding body and the functional element are clamped against each other in the locking position, whereby play between the holding body and the functional element is at least reduced.

In principle, the engaging means can be designed in any way as long as it fulfils the technical function of engaging behind the functional element in the locking position against movement in the second joining direction.

The rear gripping means of the locking unit can be implemented simply and cost-effectively if the rear gripping means of the locking unit is pre-tensioned into the locking position and can be elastically displaced by the functional element when the functional element is transferred into the second stop position.

In such a case, the rear grip means can be designed in a clip-like manner.

Embodiments of the holding device are provided in which the functional element is essentially planar, in which the first projection of the guide unit, the second projection of the joining unit and/or the functional element or the holding body form a one-piece common component and/or in which the recess of the guide unit, the locking means of the guide unit, the receptacle of the joining unit, the engaging means of the locking unit, the clamping means of the locking unit and/or the holding body or the functional element form a one-piece common component.

Because the elements of the guide unit, the joining unit and the locking unit are implemented in the holding body or in the functional element as a single-piece, common component, the holding device can be designed with reduced components.

This further simplifies assembly of the holding device. The holding body and/or the holding element can in this case be a single-component or multi-component plastic, in particular a single-component or multi-component injection-molded part.

The stability and the ability to absorb forces can be further increased if the holding device comprises at least two guide units, at least two joining units and at least two locking units, which are arranged on opposite sides of the functional element and the holding body with respect to the second joining direction.

In such a case, the two recesses of the respective guide units are arranged in such a way that they encompass a common rotation or pivot axis.

The holding body can be fixed in place on a support structure or on a vehicle component of a vehicle interior of the motor vehicle. Before arranging the functional element on the holding body, the consumer or a component of the motor vehicle can be fixed on the holding body. The functional element can then be arranged on the holding body. In order to arrange further components on the holding device, it proves to be advantageous if the functional element comprises at least one receiving means, such as a recess or projection element, for fixing at least one further component on a surface facing away from the holding body.

In order to fix the functional element 6 to the holding body 4, the holding device 2 comprises a guide unit 8 which, in the embodiment shown in the figures, comprises a first projection 12 arranged on the functional element 6 and extending in a first joining direction 10.

In addition, the guide unit 8 comprises a stop section 14 which extends transversely to the first joining direction 10 and adjoins the projection 12.

Furthermore, in the embodiment shown in the figures, the guide unit 8 comprises a recess 16 in the holding body 4, which is surrounded by an edge portion 18.

The functional element 6 and the holding body 4 can be arranged in a first stop position (see 5 ), in which the first projection 12 is inserted into the recess 16, in which the stop portion 14 is in contact with the edge portion 18 and in which the first projection 12 is in contact with one end of the recess 16.

The functional element 6 can be folded at least in the first stop position about a rotation or pivot axis 22 running transversely to the first joining direction 10. By folding about the rotation or pivot axis 22, the functional element 6 can be transferred to a second stop position (see 5 ), in which the functional element 6 rests with an end opposite the guide unit 8 in contact with the holding body 4.

The holding device 2 also comprises a joining unit 20, which is arranged in the second stop position at the end of the functional element 6 opposite the guide unit 8. In the embodiment shown in the figures, the joining unit 20 comprises a second projection 24 on the functional element 6, which extends parallel to the rotation or pivot axis 22, and a receptacle 26 on the holding body 4.

When the functional element 6 is arranged in the first stop position and in the second stop position at the same time, the second projection 24 is disengaged from the receptacle 26. By transferring the functional element 6 along a second joining direction 28 running parallel to the rotation or swivel axis 22 (see 5 ), the functional element 6 is movable in a locking position in which the second projection 24 engages in the receptacle 26 and fixes the functional element 6 against movement about the rotation or pivot axis 22.

In addition, the holding device 2 comprises a locking unit 30, which comprises a rear gripping means 32 on the holding body 4 and a rear gripping section 34 on the functional element 6. The rear gripping means 32 of the locking unit 30 engages behind the rear gripping section 34 in the locking position of the functional element 6.

In the embodiment of the holding device 2 shown in the figures, the functional element 6 comprises an L-shaped cross section in which the recess 16 is arranged. The recess 16 comprises a length extending transversely to the first joining direction 10, which enables the first projection 12 to move transversely to the first joining direction 10 from the first stop position into the locking position.

In particular, the rib-like locking means 38 is arranged on the receptacle 26. and extends in the direction of the functional element 6. The rib-like locking means 38 is arranged in such a way that in an intermediate arrangement of the functional element 6 and the holding body 4 outside the first stop position, when the functional element 6 is transferred by folding about the rotation or swivel axis 22 into the second stop position before the second stop position is reached, it rests against the functional element 6 and blocks further movement. Only when the functional element 6 and the holding body 4 are arranged in the first stop position is the rib-like locking means 38 arranged without overlapping with a wall area of the functional element 6 and movement into the second stop position is released without hindrance.

Furthermore, the locking unit 30 of the holding device 2 comprises several rail-like clamping means 40, which are arranged on the holding body 4 in the embodiment shown in the figures. The rail-like clamping means 40 have a ramp-like section, through which a distance between the holding body 4 and the functional element 6 is increased when the functional element 6 is transferred into the locking position. As a result, the first projection 12 is clamped against the edge of the recess 16 and the second projection 24 is clamped against the receptacle 26.

In the embodiment shown in the figures, the rear grip means 32 is pre-tensioned into the locking position.
