Tire parameter sensing system having a tunable circuit

Abstract: A tire parameter sensing system ( 10 ) for a vehicle ( 12 ) includes a vehicle-based unit ( 54 ) for transmitting first signals and for receiving second signals. A tire-based unit ( 34 ) is associated with a tire ( 16 ) of the vehicle ( 12 ). The tire-based unit ( 34 ) is responsive to received first signals for sensing a parameter of the tire ( 16 ) and for transmitting second signals indicative of the sensed parameter. An antenna portion ( 144 ) of the tire-based unit ( 34 ) has an impedance that varies in response to varying environmental conditions. The vehicle-based unit ( 54 ) including a tuner ( 106 ) and a controller ( 90 ). The controller ( 90 ) monitors a condition of received second signals at various settings of the tuner ( 106 ) and thereafter, sets the tuner ( 106 ) for maximizing the condition of the received second signals.

Apparatus for sensing the proximity of a vehicle to an object

Abstract: An apparatus for sensing the proximity of a first vehicle ( 79 ) to an object such as a second vehicle ( 82 ). The apparatus includes an array of sensor assemblies ( 80 ) mounted on the first vehicle ( 79 ). The sensor assemblies ( 80 ) include Hall effect sensors ( 184 ). The array of sensor assemblies ( 80 ) provide an output signal when located within the proximity of the second vehicle ( 82 ).

Vehicle occupant restraint system for a vehicle sealing element

Abstract: The invention relates to a vehicle occupant restraint system (10) for a vehicle comprising an inflator (14) and an airbag (12) connected to the inflator (14). The inflator (14) includes a mounting extension (42) which is provided for mounting the inflator (14) on a vehicle part (18) and projects through an orifice in the airbag (12). A sealing assembly (58) arranged at the mounting extension (42) is provided which clamps the airbag (12) against the inflator (14) and seals the orifice in the airbag (12). Furthermore, the invention relates to a sealing element (60) having a closed annular sealing body (68) including at least one lateral extension (64, 66) which extends in the central plane (E) of the sealing body (68).

Gas bag module for a motor vehicle steering wheel

Abstract: A gas bag module for a motor vehicle steering wheel includes a gas bag ( 10 ), a gas generator ( 12 ) mounted so as to be capable of swinging, a generator carrier ( 16 ), means ( 18 ) for bracing the gas bag ( 10 ) on the generator carrier ( 16 ), and an elastically deformable, in relation to the central axis (A) of the gas bag module encircling sealing element ( 24 ). The sealing element ( 24 ) is fastened by its free edges directly or indirectly to the gas generator ( 12 ) and to the generator carrier ( 16 ), respectively. A section ( 26 ) of the sealing element ( 24 ), which is free before a filling of the gas bag ( 10 ), is deflected by the pressure occurring in the interior of the gas bag on filling of the gas bag ( 10 ), so that it comes directly or indirectly in abutment with a support surface ( 22; 28 ).

Airbag module with a horn switch foil

Abstract: An airbag module for a vehicle steering wheel comprises a gas generator ( 1 ) with an igniter, a folded gas bag ( 2 ), an assembly plate ( 3 ), a housing ( 4 ) with an intermediate cover ( 5 ), an outer cover cap ( 6 ) optically and haptically adapted to the steering wheel environment, and a horn switch foil ( 7 ) to be actuated by pressure exerted on the cover cap ( 6 ). A planar actuating element ( 8 ) is provided between the horn switch foil ( 7 ) and the cover cap ( 6 ) and has a consistently defined spacing from the horn foil ( 7 ). Range spacers ( 9 ) in the form of pins, webs or similar are provided between the actuating element ( 8 ) and the cover cap ( 6 ) to provide an approximately constant separation distance between the actuating element ( 8 ) and the cover cap ( 6 ), at least across the entire actuating area of the cover cap.
