Description

The present invention relates to interior components for vehicles, in particular motor vehicles. But it is also the use in other vehicles such as aircraft and watercraft conceivable. In particular, the invention relates to the power supply of an electrical device which is provided in a swivel body of the interior component, which is pivotable relative to a base body. Specifically, the present invention relates to an interior component having the features in the preamble of claim 1.

In the prior art interior components, for example in the form of armrests in the center console, the rear console and the door inner lining are known. These armrests are usually adjustable and pivotable about a pivot axis for this purpose. Furthermore, these armrests can often serve as a cover for an underlying storage compartment, including the pivoting is used.

For comfort reasons, such armrests are increasingly heated. For this purpose, current systems consist of a in the armrest or the cover (swivel body) incorporated heating mat, which is powered by a fixedly mounted electrical cable with power. The cable must be routed through and out of the swivel body into the underlying body (for example the center console). By pivoting the swivel body, the cable is loaded at the transition from the swivel body to the body to train, bending and bending. These forces can lead to damage to the cable and thus a failure of the power supply. Likewise, the need for cable-compatible design of swivel body and body limits the interpretation of other requirements such as strength, stiffness, etc. Furthermore, this cable is a disruptive factor in the swivel behavior of the swivel body and disturbs the overall visual appearance. In particular, the partial visibility of the wiring is often objected.

DE 43 22 811 A1 discloses in this connection a transmission device in vehicles, with which electrical signals are transmitted via connectors with transformer coupling. For example, one part of the connector is attached to the vehicle door and the other part of the connector is attached to another part of the body. This allows a reliable signal transmission in vehicle doors, which are pivotally mounted suspended in hinges, the two parts of the connector remain even with pivotal movements of the door in a predetermined, closely spaced spatial allocation, which ensures intensive coupling.

DE 10 2009 044 729 A1 shows a system for transmitting electrical energy from a wall to a hinge hinged about a hinge axis to this wall comprises a primary electronics, which converts a mains voltage into a primary voltage for applying the primary coil, which is adapted to inductive coupling in the secondary coil To generate secondary voltage, and with a secondary electronics, which converts the secondary voltage into a suitable for an electrical energy storage and / or for an electrical load electrical operating voltage.

DE 10 2011 086 387 B3 discloses a lid, flap or flexure for a motor vehicle having at least one pivot member and at least one hinge for hingedly securing the pivot member. The hinge has a first, fixed hinge half and a second hinge half pivotable about the first hinge half, which is connected to the pivoting element. The second hinge half has a sliding contact, which is electrically connected to a functional element arranged in or on the pivoting element. The first hinge half comprises at least one electrical current-carrying contact rail which communicates with the sliding contact in at least one position of the pivoting element in an electrically conductive operative connection. The sliding contact is arranged relative to the contact rail both radially and axially movable.

DE 10 2007 005 737 A1 relates to a headrest system for a vehicle seat, in which in the headrest, a pivoting of the headrest serving engine is integrated. In the backrest of the seat, a wiring harness is laid, to which the headrest with the help of a arranged at the free end of a support rod and in the seat back, each having at least two contact elements having connector can be coupled. In this case, the contact elements of the connectors with respect to their joining direction or with respect to the central longitudinal axis of the support rod are rotationally symmetrical.

DE 103 05 681 A1 shows a can be arranged in a vehicle interior table top, which is pivotable about a table top pivot axis relative to the base part between a basic position and at least one adjustment position. At least one electrical device can be arranged directly or indirectly on the table top, wherein the electrical device can be directly or indirectly connected to a vehicle electrical system for a power supply. Between the tabletop and the base part is for the production of an electric Sliding contact between the vehicle electrical system and the at least one electrical device provided a sliding contact element, which is connected on the one hand to the vehicle electrical system and on the other hand with the at least one electrical device, preferably by means of in each case an electrical line connection, electrically conductive.

DE 10 2012 018 261 A1 shows a pivot joint assembly for a vehicle seat in a car. The vehicle seat includes a seat member, a seat back, and an electrical load integrated with a padding of the vehicle seat. The swivel joint arrangement is designed to pivot the backrest about a pivot axis relative to the seat element in different positions, wherein the swivel joint arrangement comprises an axis about which the backrest is pivotably arranged.

Accordingly, the object of the present invention is to further develop an interior component of the type mentioned at the beginning in such a way that a failure of the power supply can be prevented over a longer period as well as a freer geometry design and thus improved optics is possible.

This object is achieved by an interior component with the features of claim 1. Advantageous developments can be found in the subclaims.

The basic idea of the present invention is to replace the previously used power supply by means of a cable by a wireless, preferably contactless energy transfer. Here, there may be two basic variants, one in which a power transmission is only guaranteed if the swivel body is in a basic position, with a cover, for example, the closed position, or another, in which the power supply is ensured in any swivel positions ,

Accordingly, the present invention proposes an interior component of a vehicle having a base body and a pivoting body. The basic body can be, for example, the center console, a rear console, a door interior trim or other interior components. Optionally, a storage compartment can be integrated in the base body, which is closed by the pivoting body, which is designed in this case as a lid. By the pivoting body is pivotable relative to the base body from a basic position in at least one further position, access to the storage compartment can be made possible. The basic position would be preferred in this example, the closed position of the lid. Additionally or alternatively, it is also conceivable that the swivel body has an upper side facing away from the main body or the storage compartment opening, which is designed as an armrest. By pivoting the pivot body while the angular position of the armrest can be adjusted. Furthermore, an electrical device is provided in the swivel body and pivotable with the swivel body. This means that the electrical device moves during pivoting of the swivel body together with the swivel body relative to the main body. For example, the electrical device may be a heater. The heating device can be designed, for example, in the form of a heating mat. But there are also other electrical devices, such as a status display for closed or open center arm rest, conceivable. To provide the electrical device with electrical current, an interface is provided. According to the invention, this interface has a first element which is stationary relative to the base body and a second element which is stationary relative to the pivoting body, that is to say pivoting with the pivoting body. In other words, the first element and the second element undergo a relative movement during pivoting of the pivoting body.

For power transmission, the first and the second element according to the invention designed for contactless energy transmission. In this case, the embodiment of the invention is selected such that a contactless energy transfer, at least in the basic position, for example, when the lid is closed, while ensuring in another position, for example, with the lid open no energy transfer. As a contactless energy transfer, the inductive, capacitive and electromagnetic energy transfer come into question.

However, the inductive energy transfer is preferred. For this purpose, the first element has a primary coil and the second element has a secondary coil. For energy transfer, the magnetic field of the primary coil for generating electricity acts on the secondary coil and induces a voltage in the secondary coil. The load (electrical device) causes current to flow. In this case, the primary and secondary coils may be arranged such that the magnetic field of the primary coil acts only in the normal position, that is, for example, when the lid is closed to the secondary coil. Thus, the secondary coil can preferably be arranged at an edge of the pivot body remote from a pivot axis. This edge comes only in the basic position in the vicinity of the base body in which the primary coil is arranged complementarily. In the example of a lid, it would be preferable to provide the coils in the region of the lid closure or the lid lock. As a preferred example could the secondary coil may be provided in the region of a latching hook, while the primary coil may be provided in the region of a latching recess into which the latching hook engages.

According to a particularly preferred embodiment, however, the primary and secondary coils are arranged in the region of the pivot axis, so that the magnetic field of the primary coil acts independently of the position of the pivoting body on the secondary coil in order to induce a voltage. For example, the primary and secondary coils can be arranged for this purpose in the region of the pivot axis or the hinges, in particular in areas in which the pivot body and the base body rotate to each other, but surfaces of the two elements always remain at the same distance from each other and facing each other. It is also conceivable, for example, a hinge pin about which the pivoting body is pivotable as one of the coils and the area around a recess in which the pin rotatably engages as the other of the two coils to design.

According to an alternative design, the first and the second element can touch each other, at least in the basic position for current transmission. Again, "at least in the basic position" means that the first and second elements are electrically conductive and an electrical contact is ensured at least in the normal position, while in a pivoted to another position swivel body, the power transmission can be interrupted.

For this purpose, the first and the second element, preferably as electrically conductive contacts, are formed, which rest against each other at least in the basic position. Preferably, this is a loose contact between the two elements. In other words, they touch each other at least in the basic position. Alternatively, it is also conceivable that the first and second elements engage in the basic position. It is essential, however, that it is then a detachable by pivoting the pivot body contact.

Furthermore, it may be preferred that the first or the second element is designed as a switch and the switch can be actuated in the basic position by bringing the first and second elements into contact in order to switch the current flow. An advantage of this embodiment is that several states can be reported back, so that, for example, the determination of the current position of the center armrest can be transmitted to a within the vehicle or separately provided output device.

According to an alternative embodiment and to ensure a power supply at any pivotal positions of the pivoting body, it may be preferred that the second element during pivoting of the pivoting body slides in electrical contact with the first element and along the first element. For example, in a specific embodiment, the first element may be provided on an over-tear bar of the lid, which prevents the lid from being opened beyond a maximum position. This Überrissbügel is performed in the main body in a backdrop. In this backdrop, curved electrically conductive contacts can be provided along the pivoting path, on each of which slide corresponding pads or dome-shaped contacts on the Überrissbügel along. In this case, the Abreißbügel be formed partially circular and overlap the edge of the body, so that the Abreißbügel the edge of the body does not touch and yet fulfills its function as a tear-off.

Alternatively, it is also conceivable to arrange the first and the second element in the region of the pivot axis and to make, for example, a pin and sleeve, so that the two elements interlock, wherein the one element rotates relative to the other element while maintaining an electrical contact, for example, the pin in the sleeve or vice versa.

Further advantages and features of the present invention, which may be implemented alone or in combination with one or more of the above features, can be found in the following description of some embodiments. This description is made with reference to the accompanying drawings, in which

1 shows a schematic cross-sectional view of an interior component according to a first embodiment;

2 shows a partial perspective view of an alternative embodiment of an interior component;

3 a partial longitudinal section of a still further embodiment of the present invention schematically; and

4 a partial longitudinal section of a still further embodiment of the present invention schematically represents.

In the different representations, like reference numerals designate like or similar elements. The present invention is described in the exemplary embodiments with reference to a storage compartment cover in a center console of a motor vehicle, which also serves as an armrest serves. However, this is just one example of a variety of applications.

So shows 1 a basic body 1 in the form of a center console in which a storage compartment 2 is arranged. The storage compartment is covered by a lid, the swivel body 3 locked. In the closed position, the basic position, as in 1 is shown, the swivel body 3 one the storage compartment 2 facing underside 4 as well as a storage compartment facing away from the top 5 on. The top 5 serves as an armrest here.

The swivel body is about a pivot axis 6 relative to the main body 1 pivotable in the direction of the double arrow S to the swivel body 3 in the closed basic position, as in 1 shown, bring or to the swivel body 3 or lid to open and access to the storage compartment 2 to enable.

To the surface 5 , which serves as an armrest to heat, is a heating mat as an electrical device 7 in the swivel body 3 integrated. When opening the swivel body 3 or its pivoting about the pivot axis 6 pivots the electrical device 7 with around the pivot axis 6 ,

The electrical device 7 is via an interface 9 supplied with electricity. For this purpose, the interface 9 a first relative to the main body 1 stationary element 10 and a relative to the swivel body 3 stationary or with the swivel body 3 with pivoting second element 11 on. The second element 11 is via an electrical line 8th with the electrical device 7 connected. The same applies to the first element 10 that has another electrical line 12 is connected to the electrical system of the motor vehicle.

At the in 1 illustrated embodiment, the first element 10 the primary coil and the second element 11 the secondary coil of an inductive system, so the interface 9 designed for inductive energy transmission. To the electrical device 7 to supply electricity, the magnetic field of the primary coil acts 10 in the in 1 illustrated basic position on the secondary coil 11 , By the load, here the electrical device 7 , gets through in the secondary coil 11 induced voltage generates a current flow and the surface 5 can be heated by the heater in this exemplary embodiment. Will the swivel body 3 around the pivot axis 6 swung open, so remove the primary and secondary coil 10 . 11 from each other, leaving the magnetic field of the primary coil 10 no longer on the secondary coil 11 can work. The energy transfer is interrupted and the heater thus turned off.

Alternatively, however, it is also conceivable the interface 9 in the area of the pivot axis 6 provide, as in the embodiment in 2 is indicated. There is the secondary coil 11 in the swivel body 3 associated hinge half disposed while the primary coil 10 in the body 1 associated hinge half is positioned. The coils (first 10 and second 11 Element) or facing surfaces of the coils remain during pivoting of the swivel body 3 around the axis 6 along the double arrow S always aligned with each other, without changing their distance from each other. This ensures a continuous transfer of energy in this case. Otherwise, the embodiment differs in 2 not from the in 1 ,

In addition to a contactless energy transfer, as in relation to the 1 and 2 has been described with reference to the example of an inductive energy transfer, it is alternatively possible, the interface 9 to make with electrically conductive contacts. This will be explained below with reference to the 3 and 4 explained in more detail.

In 3 this possibility is provided by providing on a tear-off 13 of the lid formed as a swivel body 3 described. The tear-off bar 13 will be in a backdrop 14 in the main body 1 led and beats in the 3 shown maximum open position on a stop 15 to prevent the lid from tearing off. When you close the lid pivots the tear-off 13 with the swivel body 3 around the pivot axis 6 ,

the interface 9 again has two elements, one of which on the tear-off 13 and the other at the base 1 is provided. In this regard, the points in the closed state of the swivel body 3 the main body 1 facing end face 16 of the tear-off strap 13 three electrically conductive contact pads 17 as the first element. These contact pads 17 are each via electrical cables 8th with the electrical device 7 , here the heating mat, connected. A contact pad represents the negative pole, one the positive pole and one the connection to a temperature sensor. Furthermore, are corresponding to the main body 1 Gegenkontaktpads 18 (Plus pole, negative pole and temperature sensor) provided, which again via electrical cables 12 are connected to the electrical system of the motor vehicle. Will the swivel body 3 around the pivot axis 6 transferred to the closed position (basic position), as in 3 shown in dashed lines, so get the contact pads 17 in touching contact with the contact pad 18 and make an electrical connection ago, so that a power supply to the electrical device 7 is ensured via the positive and negative pole and the temperature sensor is electrically connected. Will the swivel body 3 again around the pivot axis 6 pivoted to transfer this into the open position, come the contact pads 17 and 18 again out of contact and the power supply is interrupted, much as it relates to 1 was explained.

With respect to this embodiment, it is also possible to have one or more of the contact pads 17 and 18 to design as an electrically conductive switch. This preferably applies to the positive pole of the contact pads 18 , In this case could be the supply line 12 to the corresponding contact pad are under continuous current and a transmission is only when switching the switch by the contact with the respective contact pad 17 allows.

This principle in 3 as well as the principle in 1 also works in the area of the bearing blocks, in the area of the closure and in all other places, which have the peculiarity when opening the lid, that the opposing geometries of the swivel body and body depart from each other when opening.

To similar as in 2 To ensure a permanent power supply, the design in 3 also, as regards 4 shown to be modified. In this regard, the contact pads 17 on a backdrop 14 facing side of the tear-off 13 be provided. In the scenery 14 can in turn appropriate mating contacts 19 be provided, according to the pivotal movement of the contact pads 17 around the axis 6 curved and form contact tracks. The contact pads 17 are in touching and sliding contact with the contacts 19 and slide during the pivoting movement along the double arrows S on the contact tracks 19 , so that a permanent contact during the pivoting movement can be realized.

A permanent contact would also be possible in the area of the pivot axis, as with reference to 2 for contactless energy transfer has been described. Thus, it would be possible to design a contact as a pin and the other contact as a sleeve, which engage in one another and during pivoting of the pivoting body 3 rotate relative to each other, but remain in electrically sliding contact (sliding contact).

This principle 4 and also that 2 also works at all other points that have the peculiarity when opening the swivel body from the basic position, that the opposite geometries of swivel body and body do not move away from each other, but remain at the same distance from each other.

It should be understood that the above illustrations illustrate only some embodiments of the present invention and various modifications are possible.
