Description

The invention relates to a system for the electrical separation and connection of components, in particular a line connection of removable vehicle seats on a bottom-side line connection, with the features mentioned in the preamble of claim 1.

In the course of the further electrification of the passenger compartment of motor vehicles, the arrangement of electrical devices in the arranged components, in particular in the front seat and / or in the rear seat, becomes more important. The electrical devices are, for example, a seat heater, an electric lumbar, a seat occupancy recognition, multimedia applications or electrified, verifiable safety belt systems. At the same time, the components, in particular the vehicle seats should be arranged at least removable. At present, for example, the front seats are connected via electrical connectors to the electrical supply system of a motor vehicle and must be separated when removing the seat and reconnected during installation.

In addition to an increased effort there is the risk of damage and contamination of the power cable elements, if they are open. Another difficulty arises because it is not ensured for safety-related aspects that the connection has been restored by the user. For example, security systems such as airbags or the like can not be properly reconnected, which in the event of a crash leads to a risk to the occupants.

As state of the art, which already allows a removal of a component, in particular a vehicle seat without separate separation of an electrical connector is from the published patent application DE 103 52 547 A1 a system known.

The seat is provided with power cable elements, which are connectable to arranged on the ground or on the ground contact device power contact elements. The fastening member has a stamp provided with current contact elements. The ground contact device comprises a rotatable contact bridge provided with current contact elements, wherein for the electrical connection of the seat to the ground contact device, a plunger rotates the contact bridge into a position in which the current contact elements of the plunger and the current contact elements of the contact bridge contact.

The disadvantage here is that the rotating member, the contact bridge, does not have sufficient robustness for the action taken when inserting the seat in the ground contact device action. The tolerances that lead to a contact, are very low and can be canceled in the variety of operations.

The publication DE 198 09 801 A1 discloses a contact device which signals the proper closing position of a door in the contact case via sensors.

The publication DE 39 23 351 A1 describes a movable plug which can be operated in a high temperature environment and which is further able to flexibly accommodate positional shifts which arise when a connector plug is connected to the movable plug.

The publication US 6,159,030 A presents a self-adjusting connection system for making electrical connections.

Finally, the reveals US 6,325,652 B1 a device for fixing a housing in a sliding and / or floating state, wherein a connector and a holder for such a device is explained.

The present invention is therefore an object of the invention to provide a device or a system with which an electrical connection between a seat and a ground contact device can be created, which can be solved in a simple manner and also reconnected, as far as possible Damage and contamination of the power cable elements to be avoided and the system is designed to be robust, to ensure a secure contact.

According to the invention the object is achieved in conjunction with the features of the preamble of claim 1, characterized in that a bottom-side socket unit comprises a plurality of the socket-side receiving elements and a bottom-side receiving body, the socket-side bearing elements for movable mounting of the female side receiving elements receives.

In a preferred embodiment of the invention, the component-side plug-in unit on a component-side receiving body, the Plug-side receiving elements for holding the plug element in the component-side receiving body comprises.

Preferably, the plug-side receiving elements are designed as rib-like structures, which cause a floating storage in the receiving body for tolerance compensation of the plug element relative to the bottom-side socket unit.

The movably mounted socket-side receiving elements are formed like a rocker in a preferred embodiment and are received by the socket-side bearing elements.

The bottom-side bushing unit is sealed off in the non-contact position of the system by the closure element, wherein the plug element in the connection of the system of plug-in unit and socket unit ensures that the closure element is moved from its first position to the second position, wherein the closure element in its second position the socket-side receiving elements, in particular the rocker-like socket elements, displaced in such a way that the inner contacts of the socket-side receiving elements are brought into contact with the outer contacts of the plug element.

In a preferred embodiment of the invention, the time of bringing about the contact position between the contacts of the plug element or the contacts of the socket-side receiving element by the arrangement of the closure element in its second position and by the arrangement of the female side receiving element relative to the closure element is variable. More detailed explanations at the time of bringing about the contact position between the plug element and receptacle-side female element are made in the context of the following embodiment.

Further preferred embodiments of the invention will become apparent from the remaining features mentioned in the dependent claims.

The invention will be explained below in embodiments with reference to the accompanying drawings. Show it:

6 the "Connect system" in an overall view.

1 shows an application in which the so-called "connect system" from the component side, here seat side, plug-in unit 12 and bottom socket unit 14 is executed. It is a removable vehicle seat 10 consisting of seat part 10A and backrest 10B , wherein the seat part-side plug-in unit 12 on the underside of the seat part 10A is arranged. In the in 1 shown position is the "connect system" in a non-contact position and is by placing the plug-in unit 12 on the socket unit 14 when installing the vehicle seat 10 automatically brought into a contact position. Thus, vehicle-side drives and power supply connections via the bottom-side socket unit 14 to the respective consumers who are in the vehicle seat 10 are present, be approached. Of course, the socket unit must 14 not necessarily on a floor 16 be arranged. Any conceivable opposite the plug-in unit 12 Fixed structural component is suitable for receiving the socket unit 14 ,

The details of the "connect system" according to the invention are in the 2 to 5 shown in more detail.

2 first shows a seat part side receiving body 12C as part of the plug-in unit 12 that the arrangement below the seat part 10A For example, in a frame construction of the seat part 10A allows. Within the seat part-side receiving body 12C is the plug element 12A with its plug contacts 12B educated. The perspective bottom view of the plug-in unit 12 shows that the plug element 12A via a floating mounting in the seat part side receiving body 12C is arranged. This floating storage is by plug-side receiving elements 12D and a plate 12F causes, taking on the plate 12F the plug element 12A is arranged and the seat-side receiving body 12C the plug-side receiving elements 12D takes up swimming. The plug-side receiving elements 12D are also called rib-receiving elements 12D referred as they, like 2 shows, are formed like a rib and thus flexibility and elasticity to absorb forces and to compensate for tolerances during insertion of the plug-in unit 12 in the socket unit 14 enable.

The rib-receiving elements 12D grab the plate 12F on, at the bottom of the plug element 12A is arranged. The seat part side receiving body 12C has a hole / opening 12G on, through which the floating mounted plug element 12A passes through and by corresponding larger design of the bore / opening 12G has sufficient free space to possibly tolerances between plug-in unit 12 by movement of the plug element 12A opposite the socket unit 14 compensate.

2 also shows a departure of a seat part-side pipe network 12E of the vehicle-side controls and / or power supply terminals of a control unit of the vehicle from the socket unit 14 via the plug-in unit 12 to the relevant consumers. A prerequisite is of course the contact position of the plug-in unit 12 and socket unit 14 ,

3 already shows the plug element in a first perspective side view 12A , which in socket-side receiving elements 14A is introduced while the closure element 14G '' into a second position, in 3 not closer but in 5 Socket unit shown in detail 14 , in the socket-side receiving elements 14A pushes in. The socket-side receiving elements 14A are in the exemplary embodiment rocker elements in the socket-side bearing elements 14D are movably mounted, these socket-side bearing elements 14D more exactly in 4 are visible. The other components correspond to the preceding figures.

This socket side, in 4 enlarged illustrated bearing elements 14D , which are also referred to as rocker shots or rocker bearings, allow a leading the rocker elements 14A to the in 4 not shown plug element 12A , At least one socket contact 14B is according to the arrangement of the at least one plug contact 12B inside the respective rocker element 14A arranged. In the embodiment, six socket contacts 14B and six corresponding plug contacts 12B executed. However, the number is arbitrary, depending on the application.

The bringing of the rocker elements 14A to the plug element 12A is through the closure element 14G accomplished, which when inserting the plug unit 12 through the plug element 12A from his first position 14G ' in his second position 14G '' in the rocker elements 14A is introduced. In the second position 14G '' of the closure element 14G reaches the closure element 14G one in the rocker element 14A internal rocker support surface 14F , causing the rocker elements 14A by their movable mounting in the socket-side bearing elements 14D inside to the plug element 12A and the plug contacts 12B be introduced. A contacting of the plug and socket contact 12B . 14B is thus only with little frictional movement between the contacts 12B . 14B executable.

The contact surfaces of the plug and socket contacts 12B . 14B are adapted accordingly in their contour and, of course, matched in size and positioning accordingly.

The sizes of the contact surfaces of the plug and socket contacts 12B . 14B are to be interpreted as a function of the necessary consumer currents.

5 shows the bottom-side receiving body 14C the socket unit 14 in non-contact position, ie without inserted plug-in unit 12 , wherein the closure element 14G in his first and second position 14G ' . 14G '' within the socket unit 14 is shown.

Like from the 5 it can be seen, the closure element 14G on a spring element 14H stored, wherein the spring element 14H in contact position by the plug element 12A by displacement of the closure element 14G ' to 14G " is tensioned, whereby in a non-contact position by relaxation of the below the closure element 14G located spring element 14H an automatic closing of the socket unit 14 through the closure element 14G in the first position 14G ' is effected.

During the contact position, the plate provides 12F , which rests on the area to be closed, for the sealing of the socket unit 14 ,

The socket-side receiving element 14A of course, analogous to the plug-side receiving element 12D at least one outlet or connection to the vehicle-side pipeline network 14E on.

Finally shows 6 the "connect system" in an almost complete Link position. Compared to the 1 to 5 again, like reference numerals indicate like components.

6 shows the plug-in unit 12 on the socket unit 14 , The plug element 12A can tolerances with respect to the socket-side receiving element by its floating storage 14 compensate. When plugging in the plug-in unit 12 in the socket unit 14 becomes the closure element 14G ' in the position 14G '' shifted by the plug element 12A with its tip arranged here, the closure element 14G in the position 14G '' shifts. The spring element 14H is stretched and is taut between the bottom of the socket unit 14 and the underside of the closure element 14G '' (not visible).

In this embodiment, the contact is designed so that the closure element 14G '' in its lower position on rocker support surfaces 14F the socket-side receiving elements 14A impinges and the socket-side receiving elements 14A via the rocker support / rocker support 14D in the direction of the plug element 12A relocated.

Depending on the arrangement on the rocker support 14D may be a contact time of the female side receiving element 14A or its socket contacts 14B opposite the plug contacts 12B of the plug element 12A be shortened or extended.

In principle, there is also the possibility that the socket-side receiving elements 14A on the rocker storage 14D are arranged so that when inserting the plug element 12A the plug-in unit 12 an immediate contact takes place, so here under frictional engagement during insertion of the plug-in unit 12 an immediate contacting of the plug and socket contacts 12B . 14B takes place. However, such an immediate contact is in terms of wear of the male and female contacts 12B . 14B disadvantageous, so that the rocker-like approach of the socket contacts 14B to the plug contacts 12B is preferably carried out.

To ensure that when pushing down the closure element 14G without a contact with the socket contacts 14B takes place, the socket-side receiving elements 14A in the bottom-side receiving body 14C arranged hidden in slot-like grooves or the like. When hand engaging in the bottom-side receiving body 14C is therefore no risk of electric shock by touching the rocker contacts 14B given.

In addition, the position of the respective tilting axis of the rocker elements 14A , the angular position of the rocker elements 14A Determined relative to an imaginary vertical axis, when the rocker elements when hitting the closure element 14G on the rocker support surface 14F in the direction of the plug element 12A be relocated.

The timing of the contact is also due to the depth of the rocker support surface 14F in the socket-side receiving element 14A influenced. The deeper, the later the tilting movement of the rocker elements takes place 14A instead of. It is also given by the fact that in a manual intervention by a person in the socket unit 14 the corresponding depth is not reached, so that no contact with the socket contacts 14B must be feared.

The corresponding selection of the corresponding diameter of the plug element 12A and the socket-side receiving element 14A is also part of the design, the diameters may vary in total or within the compound and also not necessarily circular shapes of the connection must be selected.

As 6 shows, closes the plate 12F after merging plug-in unit 12 and socket unit 14 the socket unit 14 in addition, so that the socket unit 14 protected against contamination. The floor 16 in which the socket unit 14 is arranged only in 1 to see. The floor 16 located in 6 between plate 12F and upper end edge of the bottom-side receiving body 14C ,
