Definitions
- timers for switching the power supply to heating elements. However, they can not detect the ambient temperature. In such systems, the heater may be turned off too late if the environment is relatively warm, or shut off too early if the ambient temperature is too low.
- the prior art also includes temperature controllers, which have a temperature sensor and a power switch. Such a temperature controller may take ambient temperature into consideration and turn off a heater when it has reached the required surface temperature. However, the temperature variation between the on and off periods is sometimes unacceptably high.
- DE 3212431 A1 describes a heating device with a relay. However, the exact arrangement of the relay is not described. Also, how the temperature is to be kept stable when the desired temperature level is reached, remains open.
- DE 102010009340 A1 describes a rapid heating device in which an additional heating wire loop is used for a secondary heating zone. For this purpose, a second type of heating wire or a double wire length to be sewn is needed. Both contribute to making the manufacture more complicated, time-consuming and expensive. In addition, this circuit consumes more power.
- CONFIRMATION COPY [07] Therefore, it is desirable to heat a seat quickly, while allowing a stable temperature in a continuous operation and a low power consumption.

- the relay for this purpose has two or more signal outputs, or is coupled via two switches, each with a heater to simultaneously switch two switches and two heaters. This allows the relay to simultaneously switch the two heaters connected thereto from a parallel connection to an electrical series connection as soon as the relay receives a switching signal from the temperature detection device.

As a result, the entire available operating voltage is applied to each of the two heaters. As a result, both heaters heat at full power and warm accordingly fast.
- This circuit is recommended when starting the heaters or when starting the vehicle in winter. But it can also be selected when a high target temperature is desired in continuous operation.
- the relay is preferably applied to an operating voltage which holds the relay in a first switching position.
- the present invention stabilizes the surface temperature, especially after the target temperature has been reached. Oscillation does not occur here. This eliminates the need for further monitoring or further intervention in this circuit concept. Such a circuit could therefore be free of other thermostats or control or regulating devices.
- the temperature detector When the temperature detector detects the initial reaching of the desired setpoint temperature, it sends a switching signal to the relay. Thereafter, the relay electrically switches at least two electrically parallel coupled thereto heaters in series one behind the other.
- the switching signal of the temperature detection device preferably causes the relay to be de-energized or no longer to be applied to electrical voltage. As a result, it automatically switches to a second, voltage-free switching state. In this condition, it remains permanently the rest of the operating time until the entire heating system is again turned on again or until the regulator device receives new setpoints manually.

- the circuit according to the invention with relays and switching of parallel connection in heating operation in series connection in continuous operation allows to limit the oscillation of an actual temperature by a temperature setpoint to a maximum of 4 ° C, preferably to a maximum of 3 ° C, suitably to 0 ° C, so that no more oscillation occurs.
- the entire heater is safer and the test effort in the run-up to production significantly reduced.
- the seating comfort is improved by the constant temperature.
- Continuous operation of heating elements in a series connection increases safety, especially in systems with higher operating voltage, eg. For buses and trucks with 24 V Batteries, as the resulting currents are significantly reduced.
- the reduction of the switching operations also increases the life of the heating system and thus also its operational safety.
- the temperature-detecting device and / or the regulating device is constructed, or its components connected to one another such that upon reaching the desired temperature, the power supply to at least one heating device is interrupted in each case.
- the temperature sensor is a thermostat, which can switch / switch the relay and / or at least one heater de-energized as soon as and as long as the target temperature is exceeded at the temperature detection device. In this way, the only negative effect of a relay failure is an oscillating temperature curve.
- At least one heating device has only one or at most two conductor loops, but is operated or operable on at least two or more power stages. Because the switch between series and series circuit allows a change in performance of the entire system, without a power change would make a larger or smaller number of conductor loops or individual heating resistors required. This reduces the design effort and material costs of the system.
