A pressure medium distributor, for a pneumatic adjustment arrangement of a vehicle seat. The pressure medium distributor has a distribution element including at least one first and one second film connected to each other along a connection seam in order to form a first and at least one second pressure medium chamber. The pressure medium distributor has a first pressure medium inlet line to admit the pressure medium into the first pressure medium chamber, and at least one second pressure medium inlet line to admit the pressure medium into the at least one second pressure medium chamber, At least one first pressure medium outlet line is provided for discharge of the pressure medium from the first pressure medium chamber, and at least one second pressure medium outlet line is provided for discharge of the pressure medium from the second pressure medium chamber creating a pressure medium distributor which is flexible.

A pump valve module and operating method, a solenoid valve-based pump valve module for providing a massage function for a vehicle seat, and a vehicle seat are disclosed. A composite solenoid valve in the pump valve module includes deflation solenoid valve and inflation solenoid valve connected in series and formed integrally by injection molding. A first part region of the inflation solenoid valve is connected to air source. A second part region of the deflation solenoid valve is connected to inflated bag. A second part region of the inflation solenoid valve is connected to a first part region of the deflation solenoid valve. Inflation is implemented when the inflation solenoid valve is powered on and the deflation solenoid valve is de-energized. Deflation is implemented through a third part region of the deflation solenoid valve when the inflation solenoid valve is de-energized and the deflation solenoid valve is powered on.

A vehicle system includes: at least one of: a sensor configured to measure an amount of a chemical in air within a passenger cabin of a vehicle; and a camera configured to capture images within the passenger cabin of the vehicle; and a control module configured to: detect smoking within the passenger cabin based on the at least one of the amount of the chemical and at least one of the images; and in response to smoking being detected within the passenger cabin, adjust operation of at least one of a luxury feature of the vehicle and a comfort feature of the vehicle.

A seat seating portion vibrating apparatus with high reliability and high durability. The seat seating portion vibrating apparatus includes an electric motor that comprises a rotary shaft that is disposed along a seating surface of a seat; a weight that is attached to the rotary shaft; and a case for containing the electric motor and the weight therein. The case is provided therein with a wiring space for flexing and connecting a harness for the electric motor, and is provided with a harness extending portion wherein the harness extends downward, perpendicular to the seating surface.

Armrest device for utility vehicle seats, wherein the armrest device has a plurality of first control elements and at least one second control element, wherein by means of selecting and actuating one of the first control elements which is arranged on an upper surface of the armrest device, seen in a height direction, a vehicle function can be assigned to the selected first control element and by means of actuating the second control element, which is arranged on a side surface of the armrest device and is connected at least by means of a signal to the selected first control element, the vehicle function is adjustable.

A seat having a backrest and a seat cushion includes rows of adjusting elements, respectively, which adjusting elements are arranged above one another, on both sides of the longitudinal center plane of the seat. By alternately applying the adjusting elements mutually arranged in a vertically staggered manner in the two halves of the seat, a rotational movement can be actively applied to a seat user's back and possibly pelvis, which rotational movement corresponds to the rotational movement of the back, and possibly of the pelvis, when walking.

A vehicle seat element, in particular seat pan, backrest or seat headrest, having a cushion facing a vehicle occupant, a covering and at least one vibration massage unit, arranged underneath the covering in a recess in the cushion and consists of an electric drive and a driven unbalanced mass, arranged at one end of the elongate vibration massage unit, characterised in that the vibration massage unit is supported in the recess only at points, in lines and/or in small areas and is spaced from the end of the vibration massage unit at which the unbalanced mass is arranged, and the substantial portion of the walls of the recess is spaced from the vibration massage unit. An insert element for a vehicle seat element of this type, a cushion for a vehicle seat element of this type, and a method for producing a vehicle seat element of this type.

A method for configuring a massage program of a massage device of a vehicle seat by an electronic control unit, which is connected indirectly or directly to at least one control unit for the vehicle seat of the vehicle. When configuring the created massage program, at least one element of the vehicle seat, to which element pressure can be applied, is controlled by means of the electronic control unit, wherein the vehicle seat control unit outputs the massage program after the start of the massage program in accordance with the configuration performed by controlling the individual elements, to which pressure can be applied, in the vehicle seat. It is provided that, within the configuration for creating the massage program, at least one configuration step is performed by the electronic control unit and at least one configuration step is performed directly at the seat part and/or at the backrest part.

A distributed control system for a vehicle seat includes a control module for communicating on a single communication bus and a plurality of nodes connected to the control module via the communication bus, wherein each of the plurality of nodes are associated with a load device and each of the plurality of nodes comprises a logic component specific to the load device.
