Abstract: A frame for receiving a heating element for an electric heater of a ventilating, heating and/or air conditioning unit of a vehicle, in particular. The frame is shaped in the form of a hollowed-out box whose large faces, intended to be traversed by airflow conveyed by the unit, are held at a distance from each other in order to create between them a space for receiving the heating element. The frame is made of a single part in which means for holding the heating element inside the space are located in the area of the large faces.

Abstract: The invention concerns a device for protecting an electric source adapted to power an electric member comprising a test unit (6) adapted to deliver a signal (8) representing the availability of the electric source (2), to a control unit (10). The unit (10) determines an operating mode of the electric member (4) wherein the power consumption of the electric member is a function of the availability signal (8) received from the test unit (6). The electric source (2) can power directly the electric member (4) and the control unit (10) can act on the electric member itself. The control unit (10) can also be interposed between the electric source (2) and the electric member (4) to modify at least one characteristic of the current powering the electric member.

Abstract: A motor for moving a flap for distributing a flow of air in a duct of a heating, ventilation and/or air conditioning installation is supplied with voltage. A power-regulation module is mounted in series with the motor, and includes at least one positive-temperature-coefficient resistor, so that, when the flap reaches an open or closed position, the motor is blocked. This results in an increase in the current strength in the circuit, causing an increase in the value of the resistance, and this results in a reduction in the current strength and in the voltage at the terminals of the motor.
