Abstract

A remote control unit carries control keys and possesses in its back face a battery housing with central and peripheral power supply contacts, and also with signal transmission contacts. An active support carries a portion in relief suitable for penetrating into the housing of the unit to take the place of the power supply battery. Two power supply terminals are connected to a power supply line and arranged so as to bear against the respective power supply contacts of the unit when the portion in relief is inserted and locked in the housing of the unit, with the same applying for signal transmission terminals that are arranged on the portion in relief in positions that correspond to the transmission contacts of the unit.

Claims

1. An assembly for remotely controlling “

hands-free”

multimedia and/or telephony equipment incorporated in a motor vehicle, the assembly comprising;

a) a remote control unit comprising;

a visible face carrying control keys and/or buttons;

a back face with a housing for a power supply battery; and

radio-frequency transmitter means for wirelessly transmitting control signals to the remote equipment; and

b) a removable cover separable from the unit and suitable for closing the housing and holding in place a power supply battery placed in the housing;

wherein the following are provided inside the housing of the remote control unit;

a central power supply contact and a peripheral power supply contact suitable for pressing against respective poles of the power supply battery inserted in the housing; and

signal transmission contacts located on the bottom of the housing for transmitting control signals by wire to the remote equipment; and

wherein it further comprises;

c) an active support comprising;

on a back face, fastener means for fastening to the dashboard of the vehicle;

on a front face, securing means for securing to the back face of the unit, and also a portion in relief suitable for penetrating into the housing in the unit to take the place of the power supply battery in the absence of the removable cover;

an electrical power supply line suitable for being connected to the on-board network of the vehicle;

a transmission line suitable for being connected to the remote equipment;

two power supply terminals connected to the power supply line and arranged on the portion in relief in a central position and in a peripheral position in such a manner as to press against the central and peripheral contacts respectively of the unit when the portion in relief is inserted and locked in the housing of the unit; and

signal transmission terminals placed on the portion in relief in positions corresponding to the transmission contacts of the unit when the portion in relief is inserted and locked in the housing of the unit.

2. The assembly of claim 1, wherein the signal transmission contacts comprise a diametrically opposite pair of contacts in the form of circular arcs, and wherein the control signals are transmitted by wire to the remote equipment by asynchronous serial transmission.

3. The assembly of claim 1, wherein the remote control unit incorporates:

detector means for detecting an established connection on the signal transmission contacts; and

means for deactivating the radio-frequency transmitter means on detecting said connection.

4. The assembly of claim 1, wherein the remote control unit incorporates:

backlighting means for backlighting the control keys and/or buttons;

detector means for detecting an established connection on the power supply contacts with the on-board network of the vehicle; and

means for activating the backlighting means on detecting said connection.

5. The assembly of claim 1, wherein the means for locking the cover to the unit are bayonet fastener means suitable for enabling the cover to be put into place on the unit in an angularly offset position, and then enabling it to be locked by being turned through a fraction of a turn to a final, utilization position.

6. The assembly of claim 1, wherein the securing means for securing the active support to the unit are bayonet fastener means suitable for enabling the unit to be put into place on the active support in an angularly offset position, and then enabling it to be locked by being turned through a fraction of the turn to a final, utilization position.

7. The assembly of claim 1, further comprising:

d) a passive support comprising;

on its back face, fastener means for fastening to the dashboard of the vehicle; and

on its front face, securing means for securing to the back face of the unit provided with the power supply battery and the removable cover.

8. The assembly of claim 7, wherein said securing means comprise hooks suitable for reversibly co-operating with corresponding recesses formed in the removable cover and/or in the back face of the unit.

9. The assembly of claim 8, wherein the securing means for securing the passive support, and the securing means for securing the active support to the back face of the unit each comprise respective hooks suitable for co-operating with the same recesses of the unit.

10. The assembly of claim 8, wherein the hooks and the corresponding recesses are configured in such a manner as to enable the unit to be put into place on the plate in an angularly offset position and then locked by being turned through a fraction of a turn to a final, holding position.
