Abstract: A method for controlling a vehicle seat valve, the piston thereof is actively displaced from a closed position into an open position or vice versa by an electrical voltage being applied to an electromagnetic drive means. The power of the drive means is regulated via an effective voltage which can be changed by means of pulse width modulation of an impulse voltage that has a constant frequency. In order to displace the piston from its closed position toward its open position, a duty cycle of the pulse width modulation is firstly increased from a rest duty cycle to a starting duty cycle of less than 100%, and the duty cycle is only raised to a final duty cycle when the piston has reached the open position and/or if a blockage impeding the displacement of the piston before it reaches its open position is identified.

Abstract: A vehicle seat includes a pump for operating a seat cushion adjuster or a seat massage system and a seat frame structure. The pump is coupled to an electrical supply line and a pressure line. The pump is designed without a soundproofing enclosure. At least one noise-reducing or vibration-damping coupling device is provided. The coupling device and pump being attached via a first section to the seat frame structure. The coupling device is attached directly to the pressure line of the pump or to the electrical supply line of the pump via a second section.
