Vehicle seat with a base frame and a seat frame moveable relative to that base frame
View Patent ↗The invention relates to a vehicle seat comprising a base frame and comprising a seat frame which can be adjusted relative to the base frame, and comprising a gas spring which acts between this base frame and this seat frame and which is supported against the seat frame, wherein at least one pressure source and at least one valve device which is in fluid connection with this pressure source are provided, and in that furthermore a manually operated actuation element is provided for adjusting the vehicle seat, wherein this at least one valve device is arranged on or in the actuation element.
1. A vehicle seat device in fluid connection with a pressure source and in signal communication with a compressor, the device comprising:
a housing;
at least one switch attached to the housing, the at least one switch for supplying the compressor a drive signal and for controlling a level control system;
at least one valve attached to the housing, the at least one valve device is in fluid connection with the pressure source; and
a manually operated actuation element that rotates about an axle,
wherein the manually operated actuation element makes direct contact with the at least one switch when the actuation element has been manually operated to a first position, thereby causing the at least one switch to generate an activate signal and send the activate signal to the compressor, and
wherein the manually operated actuation element makes direct contact with the at least one valve when the actuation element has been manually operated to a second position, thereby causing the at least one valve to discharge air from the pressure source.
2. The vehicle seat of claim 1 , wherein the at least one valve device comprises a 2/2-way valve and a 3/2-way valve.
3. The vehicle seat of claim 1 , further comprising a pivot axle mounted in the housing, wherein the manually operated actuation element is configurable to pivot about the pivot axle upon actuation.
4. The vehicle seat of claim 1 , wherein the at least one valve device comprises a solenoid valve having a magnet provided with monoflop control.
