Variable seat heating has sensors distributed over seat surface and associated with areas of heater that are selectively switched on when pressure acts on associated sensors

摘要

The device has a heater (4) and a pressure sensor responsive to the weight of a person to switch on the heater. Sensors are distributed over the seat surface and associated with areas of the heater that are selectively switched on when pressure acts on the associated sensors. The sensors form a matrix of contact elements that are separate in the no-pressure state and that make contact under pressure.
