Abstract: In a microphone mounting for a hands-free system in automotive vehicles, the microphone is mounted on the seat belt. In one embodiment the microphone is seated in a sheath which is fastened to the upper belt deflection and through which the belt can freely pass. The sheath consists of two mutually displaceable flat sleeves, of which the lower one accommodates the microphone whose position relative to the passenger's mouth can be adjusted in an optimum way by a mutual displacement of the two sleeves. In another embodiment the microphone is provided at its side facing the belt with contacts that are brought into electrical contact with conducting wires integrated into the belt so as to be connected to the telephone circuit.

Abstract: A hands-free device for an automotive vehicle is designed as a unit consisting of loudspeaker (12) and microphone (20), in which the loudspeaker (12) which can be hung with a hook (6) onto the upper edge (4) of the B-pillar trim (2) is connected via an arm (18) to the microphone (20). A guide clip (26) which is fastened to the arm encompasses the safety belt (30), so that when the belt is fasted the microphone (20) rests in the neck/chest area of the driver and thus near the driver's mouth without presenting any obstacle. The loudspeaker (12) which is positioned near the B-pillar is positioned equally close to the ear, thus creating optimum preconditions for speech distinctness or intelligibility during speaking and hearing. On the other hand, in the unfastened state of the belt, the unit is suspended in the area between B-pillar and seat back without presenting any obstacle.

Abstract: In a hands-free device which is particularly suited for automotive vehicles, the loudspeaker (20) is arranged in a housing (16) which is loosely seated on the belt and which is fixed with a mounting to the B-pillar near the ear. The microphone (30) is positioned within a microphone housing (18) which can be displaced on and fixed to the belt (10), and communicates via an infrared path with a circuit provided in the loudspeaker housing. An accumulator which powers the microphone circuit is charged via charging contacts (34, 36) between microphone housing and loudspeaker housing when the microphone housing (18) is pushed towards the loudspeaker housing (16). Power can be supplied via a cable from the car socket, and the signal transmission between free-hands device and mobile telephone takes place via a plug connection with the head-set jack of the telephone.
