A proximity and contact sensor device in motor vehicle steering wheels, characterised by comprising an extendable band (2), the length of which is slightly less than the circumference of the steering wheel and of which one surface has fixed to it at least one conductive track (6, 6', 6") covered with a biadhesive layer (14), said conductive track consisting of a flat metal path obtained by treating a metal sheet applied to said extendable band, said conductive track being connected to a multi-channel capacitive sensor circuit (8) connected by a field bus (10) to the vehicle control unit (12).. |
