A vehicle seat having a heating device arranged in connection with the vehicle seat and connected to a control unit which includes a current-feeding apparatus for feeding a current to the heating device. The vehicle seat also includes a temperature sensor connected to the control unit for detecting the temperature at the heating device. The control unit is arranged to feed the current if the measured temperature falls below a pre-determined temperature value. An occupant sensor is also provided for detecting the presence of an occupant or an object in the vehicle seat. The occupant sensor is arranged as a single integral unit together with the heating device in the vehicle seat.
