Abstract

The contact unit has a body side locking bolt forming a reversible body side connection of a vehicle seat with respect to a vehicle body (200). A seat part side contact element (113) of the body forms an electrical contact region (K) with a body side contact element (213) of the body when the contact elements are mechanically displaced relative to the body such that an electrical self-contacting connection is formed between the contact elements in addition to a mechanical connection. The seat part side contact element is arranged in a region of a pawl (110) of the seat.

Description

The invention relates to a contact device between a vehicle seat, in particular a removable vehicle seat and a body comprising a seat part side and a body-side contact element. The contact elements of the contact device form a self-contacting power supply for the vehicle seat in the installed state of the vehicle seat.

From the DE 203 07 185 U1 is a device for contacting the lines of electrical components of a vehicle equipment, in particular a vehicle seat, known. Through them, both the arranged in the vehicle seat electrical consumers and the installed in the vehicle seat components for control or the electrically connected to the electrical consumers, outside the vehicle seat positioned control devices associated electrical lines with the intended for the vehicle seat, provided with plugs electrical cables of a wiring harness of a motor vehicle are conductively connected. The specific for the driver's seat electrical lines of the wiring harness of the motor vehicle are mounted with their connectors on a support plate such that each, a certain electrical load or a specific control device associated connector always occupies a parking position on the support plate in the same place. Thus, the plug is always positioned in a plug-in position in which after the attachment of the holding plate with the electrical lines of the wiring harness of the motor vehicle with their prepositioned plugs on the seat pan of the vehicle seat, the respective coded, the respective function of the electrical components associated electrical line of the Vehicle seat is located. This confusion of the plug position when contacting can be largely avoided. However, there is a problem that the connectors of the wiring harness or the wiring harnesses are difficult to insert into the respective connectors of the vehicle seat.

Based on that offers DE 10 2004 406 26 19 A1 a further developed contact device for a driver's seat with a seat-side plug device and a line-side connector means, which can be inserted into the seat-side plug means for forming an electrical connector and latched in this state with this. A locking device serves to lock the line-strand-side plug device to a vehicle component for the purpose of producing the electrical plug-in connection, wherein the lock can be released by the latching force of the two plug devices. Thus, the connector can be made by moving the vehicle seat in a stop position. However, this solution also requires because of the connector to be produced a relatively accurate arrangement of plug and plug-in coupling, so that the connector despite the existing tolerances between the vehicle seat and seat rail when locking the vehicle seat against the seat rail is safe to produce. For this purpose, the plug-in coupling is floating. This solution also appears very expensive and is in particular for removable seats, which are often replaced if necessary, with respect to repetitive stress rather unsuitable.

The invention is based on the prior art, the task for vehicle seats, especially for removable rear seats to ensure an easy-to-use and secure power supply. Another sub-task is to ensure personal safety. It should be ensured that during installation, while installed and when removing live parts are inaccessible. In principle, the power supply according to the invention serves electrical consumers arranged in the vehicle seat, in particular the components installed in the vehicle seat for controlling or the control devices which are in operative connection with the electrical consumers.

It is understood that the following technical solution of the so-called self-contacting power supply of a vehicle seat not only in removable rear seats, but in other seats each row of seats can be equally used. The invention is based on a contact device between a vehicle seat, in particular a removable vehicle seat, and a body comprising a seat part side and a body side contact element.

The object is achieved in that the seat part-side contact element is arranged in the region of a receptacle of the vehicle seat. By means of the recording via a body-side locking element is a reversible body-side connection of the vehicle seat relative to the body. According to the invention, an electric contact is produced between the seat part-side contact element and the body-side contact element in a contact region only when the seat part-side contact element has mechanically displaced the body-side contact element relative to the body.

Due to the mechanical displacement of the body-side contact element occurs within the body-side contact element to an electrical connection between the body-side contact element and a current-carrying supply line. By this contact closure one or more circuit / e is closed up to one or more consumers in the area of the vehicle seat via the contact in the contact region of the two contact elements.

The electrical connection is referred to as self-contacting, since the contact is made in the contact area by the vehicle seat is received and locked body-side with its receptacle. Without further action, the contact is made in the contact area, so that the vehicle seat as of itself makes the contact between the vehicle seat and body, whereby the self-contacting electrical connection, which precedes a mechanical contact, is ensured.

By this explanation, it becomes clear what constitutes a significant advantage of the present invention. In order to ensure the power supply to the electrical consumers of the vehicle seat, the user does not have to insert an electrical plug into a plug-in coupling provided for this purpose. The handling is thus particularly simple, since the user does not even notice when installing the vehicle seat in the body, that he also produces an electrical connection between the electrical system and the electrical consumers of the vehicle seat.

Representing all possible applications are called as electrical power consumers, for example, a buckle recognition or a seat heating.

In a preferred embodiment of the invention, the self-contacting power supply to the contact area, which is arranged in the region of at least one seat receiving the vehicle seat. The contact area is formed between the seat part side and the body-side contact element. It is possible to realize the contact area both in a front and / or in a rear seat receptacle.

The technical solution according to the invention can be implemented in various design variants.

The variants have some identical design features.

In a preferred embodiment of the invention, the receptacle, which is designed as a pawl in both embodiments, on its surface at least one side, facing the body-side contact element, a plastic insulation. Advantageously, it is ensured by this plastic insulation that when installing and removing the vehicle seat inadvertent contact between the pawl made of a conductive material and the accidentally mechanically operated and therefore energized body-side contact element is made. This measure serves the task of ensuring personal safety. The user is protected from the fact that the vehicle seat comes into contact with live components.

According to the invention, it is provided in a preferred embodiment of the invention that a seat part-side contact panel is arranged in or on the plastic insulation, which leads and surrounds the seat part-side contact element. On the one hand, this contact panel also serves to ensure personal safety and always ensures that a flow of current existing after installation of the vehicle seat is insulated to the outside within the seat part-side contact element. On the other hand, the aperture simultaneously takes over the leadership of the contact element.

In a preferred embodiment, in particular in order to enable a simple production, the plastic insulation and the seat part-side contact panel are integrally formed. In a preferred embodiment, an injection molded part can be produced, which has the corresponding opening in the contact panel for the seat part-side contact element.

There may also be applications in which the receptacle is provided with a separate element for plastic insulation, which has a recess for the seat part side also formed as a separate element contact panel. In such a case, the plastic insulation and the seat part-side contact panel is made in two parts.

In a further preferred embodiment of the invention, the body-side contact element is also disposed within a body-side contact panel. On the one hand, this body-side contact panel also serves to guide the body-side contact element and, because the panel surrounds the body-side contact element, ensures that persons are protected from possible current flow, since the panel consisting of a non-conductive material houses the current-carrying components.

For both embodiments, in a preferred embodiment of the invention further, that the mechanical displacement of the body-side contact element relative to the body by a pressing force of the seat part-side contact element, which takes place against the force of a blind side or body-side supporting spring element, wherein the body-side contact element within the body side Contact diaphragm is reversibly displaceable against the biasing force of the spring element.

The two variants differ mainly in the effective direction of the pressure force exerted by the seat part side on the body-side contact element and the associated change in the arrangement of the contact elements relative to each other.

In the first embodiment, the seat part-side contact panel and thus the seat part-side contact element is arranged laterally of the receptacle, wherein the contact panel has a relation to the lateral alignment offset by 90 ° aperture. By this arrangement, an outgoing from the recording, substantially radial effective direction of the pressure force of the seat part-side contact element relative to the arranged in the radial direction of the receptacle body-side contact element can be effected.

In the second embodiment, the seat part-side contact panel is also disposed laterally of the receptacle, wherein the contact panel, however, has an aperture extending in the axial direction of the receptacle. As a result of this arrangement, a body-side contact element arranged essentially in the axial direction of action of the pressure force of the seat part-side contact element can be brought into engagement with the receptacle arranged in the axial direction of the receptacle.

In the first embodiment, the body-side contact panel is connected directly to the body. In the second embodiment, the body-side contact panel is indirectly connected via an insulating insert with the body. For the body-side contact panel and the insulating insert applies that these two components can be produced as a one-part or multi-part injection-molded element.

The assembly or installation of the removable vehicle seat thus takes place as follows:
When installing the vehicle seat or locking the intended as a receptacle latch in the designated locking element, preferably a body-mounted locking bolt, the insertable into the body-side contact panel, body-side contact element is displaced by the seat part-side contact element in the designated guides within the body-side contact element, between the contact elements, a circuit is closed when the retractable body-side contact element forms an electrical contact with an energized onboard supply line.

The seat part side contact is thus energized only when the vehicle seat has been brought with its pawl in the appropriate position and the body-side contact element has been displaced by the seat part side contact in the designated guides and makes contact with the power supply of the electrical system.

In a preferred embodiment, the body-side, retractable contact element against the force of the prestressed spring element is inserted and when removing the seat, the contact element is pushed back into the original position and protects people from the live line, since the body-side contact element, if it is not in the body-side contact panel is inserted, is de-energized and completely closes the aperture of the body-side contact element.

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

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

The associated removable removable vehicle seat described in each case 100 is located in the vehicle in its normal position, where a user in the direction of travel forward on the vehicle seat 100 sitting.

First embodiment variant:

1A shows a perspective view obliquely from above on the structure of a rear seat 100 in the rear body area of a body 200 a vehicle in a first embodiment. Recognizable is a latch 110 , as a frame-fixed recording of the rear seat 100 opposite the body 200 serves. Not visible is a body-locking pin 210 as a body-side locking element. This will be on 2 B and the description made within the second embodiment. Below the latch 110 is a body-side contact element 213 shown.

In this 1A Although, in principle, the position of the contact device within the vehicle is recognizable, however, the contact area K is barely visible in detail.

That's why shows 1B an enlarged perspective view obliquely from above on the contact area K of the first embodiment.

In this 1B is only the lower area of the latch 110 shown. The handle 110 has an in 1B invisible pawl opening in the body-mounted locking pin 210 intervenes. 1B shows the tail of a locking lever 114 acting as a locking element of the rear seat 100 opposite the locking pin 210 acts. The pivot axis of the locking lever 114 is coaxial with the axis of the locking pin 210 arranged, wherein the locking lever 114 at the latch 110 is mounted pivotally about the pivot axis. The axis of the locking bolt 210 and the pivot axis of the locking lever 114 whose opening for locking the rear seat 100 in the locking pin 210 engages and the the rear seat 100 by pivoting against the locking pin 210 reversibly locked, each run in the y-direction transverse to the direction of travel x.

The handle 110 has a plastic insulation 111 on. In a one-piece design includes the plastic insulation 111 a contact panel 112 , The disc-like plastic insulation 111 is with her to the latch 110 facing side on the latch 110 attached, preferably glued. Other types of connection are conceivable. Starting from the y-axis of the pawl 110 has the seat part side contact panel 112 an aperture which faces in the radial direction. In this aperture sits a seat part-side contact element 113 , which with at least one electrical line for at least one electrical load in the rear seat 100 communicates. This seat part-side contact element 113 is as long as the rear seat 100 not yet in his 1B End positions shown is, de-energized.

Also in the radial direction, starting from the y-axis of the pawl 110 is a body-side contact panel 212 in which a body-side contact element 213 is arranged.

The body-side contact panel 212 is with the body 200 connected, being inside the bodywork 200 an outgoing from the electrical system power supply cable into the body-side contact panel 212 is guided into it.

The illustrated body-side contact element 213 However, the circuit closes only when it passes through the seat part-side contact element 113 mechanically in the body-side contact panel 212 is pressed. The mechanical force is from that in the bodywork 200 used fund seat 100 from the seat part side contact element 113 on the body-side contact element 213 according to the force arrow F, which also shows the direction of force substantially transmitted in the radial direction. When installing the rear seat 100 At first, the mechanical self-contacting takes place, followed by the electrical self-contacting.

After the body-side contact element 213 through the seat part-side contact element 113 in the contact panel 212 the circuit is closed. In 2 B is visible that the contact area K is inaccessible from the outside, since substantially outer non-conductive plastic parts protect the contact area K. Persons can thus not get into the current-carrying contact area K.

The body-side contact element 213 is, as not shown, spring-loaded in the contact panel 212 guided arranged, that is, when inserting the contact element 213 the slightly biased spring element is compressed, whereby the contact element 213 after removal of the vehicle seat 100 in its original position, where it is essentially outside the body-side contact panel 212 is and no contact with the power supply line forms, returns.

Second embodiment variant:

2A shows analogously to 1A another perspective view obliquely from above on the structure of the rear seat 100 in the rear bodywork of the body 200 of the vehicle in a second embodiment. Visible is again the latch 110 , as a frame-fixed recording of the rear seat 100 opposite the body 200 serves. Again hardly visible is the body-fixed locking pin 210 ,

To better clarify the locking of the rear seat 100 opposite the body 200 serves the 2C , The 2C shows an enlarged perspective view from above of the contact region K of the second embodiment. However, the visible locking mechanism is executed analogously in the first and in the second embodiment. The handle 110 engages with its opening in the body-mounted locking pin 210 , The locking pin 210 lies on a y-axis, which is transverse to the direction x. Coaxial with this is on the latch 110 the pivoting locking lever 114 arranged. The locking lever 140 has in turn an opening which also in the locking pin 210 engages, causing the latch 110 opposite the locking pin 210 is fixed until the locking lever 114 returns to its unlocked starting position and the rear seat 100 releases.

In 2A Although, in principle, the position of the contact device within the vehicle is recognizable, however, the contact area K is barely visible in detail. It is visible, however, that the body-side contact element 213 not below the latch 110 is arranged, but next to the latch 110 located.

For better clarity shows 2 B a further enlarged perspective view obliquely from above on the contact region K of the second embodiment.

In this 2 B Again, only the lower portion of the pawl 110 shown. 2 B also shows the end piece of the locking lever 114 who is the rear seat 100 opposite the locking pin 210 locked.

The handle 110 also has a plastic insulation in the second embodiment 111 on. In a one-piece design includes the plastic insulation 111 again a contact panel 112 , The disc-like plastic insulation 111 is as in the first embodiment with her to the latch 110 facing side on the latch 110 attached, preferably glued.

Deviating from the first embodiment, the seat part side contact panel 112 starting from the y-axis of the pawl 110 an aperture which faces in the axial direction. In this aperture, the seat part-side contact element sits 113 , which with at least one electrical line for at least one electrical load in the rear seat 100 communicates. The seat part-side contact element 113 is initially energized.

In the second embodiment, the body-side contact panel lies in the axial direction, starting from the y-axis 212 in which the body-side contact element 213 is arranged. For personal safety is the body-side contact panel 212 integral part of an insulating insert 220 which is in a recess of the bodywork 200 is arranged. In this recess, the pawl engages 110 in the installed state of the rear seat 100 one.

By installing the rear seat 100 again, as in the first embodiment variant, the self-contacting of the contact elements 113 . 213 instead of. The illustrated body-side contact element 213 However, the circuit closes only when it passes through the seat part-side contact element 113 mechanically in the body-side contact panel 212 has been pressed. The mechanical force is from that in the bodywork 200 used fund seat 100 from the seat part side contact element 113 on the body-side contact element 213 in accordance with the force arrow F, which also shows the direction of force substantially transmitted in the axial direction.

As in the first embodiment, the circuit is closed after the body-side contact element 213 through the seat part-side contact element 113 in the contact panel 212 has been pushed. The contact area K is also almost inaccessible from the outside in this second embodiment, since substantially non-conductive plastic parts on the outside protect the contact area K from direct access by a person.

Analogous to the first embodiment, the body-side contact element 213 spring loaded in the contact panel 212 arranged arranged. The mechanical force is due to the expansion of the rear seat 100 not closer to the body-side contact element 213 exerted, the spring element presses the body-side contact element 213 back to its original position.

The second embodiment has the advantage that the contact area K is not at the bottom of the body 200 lies, but lying freely between the latch 110 under the body 200 opposite the floor of the body 200 z direction is arranged elevated. By this arrangement, the contact area K is protected from dirt and moisture in the body area.
