Abstract: A fluid component, a vehicle comfort system, and a method for operating the system in which the fluid component has the function of a pressure sensor and/or valve for a fluid-conducting system of a vehicle comfort system, and in which at least one actuator is accommodated, and preferably in a preferably fluid-tight or non-fluid-tight housing of the fluid component. Each actuator has at least two electrodes and at least one section arranged between them having an electroactive polymer (EAP), or a plurality of sections having an electroactive polymer (EAP) layered on top of one another.

Abstract: A module support arrangement for attachment to the seat structure of a motor vehicle seat and for fixing pneumatic components or non-pneumatic components having a module support with a front side and a rear side opposite the front side. Optionally, the module support arrangement has at least one further component, wherein the module support arrangement comprises a housing for receiving a pneumatic pump. At least one part of the housing or a plurality of parts of the housing is integrated into the module support.

Abstract: A module carrier arrangement for attachment to the seat structure of a motor vehicle seat and for securing pneumatic components or non-pneumatic components has a module carrier with a front side and a rear side opposite the front side. Optionally, the module carrier arrangement has at least one further component, wherein air ducts and/or air duct portions are integrated in the module carrier and/or in the at least one further component.

Abstract: A motor vehicle seat having a backrest and a seat part and an adjustable sidewall arranged on the backrest and/or the seat part, which sidewall comprises an adjustment mechanism having a stationary portion and a lever portion pivotable about a pivot axis, and having at least one fluid-fillable bladder arranged between the stationary portion and the lever portion for adjusting the relative angular position thereof, wherein the lever portion comprises two wing portions which are arranged on either side of the pivot axis, and the bladder is arranged between a first wing portion and the stationary portion, wherein a preload torsion spring engages by a first spring portion on the stationary portion, and engages by a second spring portion on the second wing portion, of the lever portion, such that it exerts a preload force which pushes the first spring portion in the direction of the stationary portion.

Abstract: A functional apparatus for a vehicle seat having at least one expansion member having at least one cavity, the volume of which can be changed, at least in part, by a fluid which can flow into and out of said cavity, a fluid reservoir comprising at least one cavity being provided, which cavity is connected in a fluid-conducting manner to the cavity of the expansion member. The fluid reservoir cooperates with an actuator assembly by means of which the cavity of the fluid reservoir can be actively compressed, with at least partial displacement of the fluid contained therein into the cavity of the expansion member.

Abstract: A vehicle seat having a backrest and a seat part, as well as at least one sidewall arranged on the backrest or on the seat part, the sidewall having two support portions that are coupled together, by a coupling means, and are movable relative to one another, between which support portions at least one hollow body that can be filled with fluid is arranged, the relative position of the two support portions with respect to one another, and thus the outside contour of the sidewall, being variable by filling or emptying the at least one hollow body. The coupling means is designed such that, upon filling or emptying of the at least one hollow body, the two support portions are variable relative to one another, both in translation and in their angular position.

Abstract: An arrangement for manipulating the flow of a fluid into a fluid actuator, preferably of a seat, has a base body having an opening designed to introduce the fluid into the base body, and at least one further opening provided for forwarding or discharging the fluid introduced into the base body. Means for producing and/or interrupting a fluid-conducting connection between the openings are provided. The means comprise such additional means that can be charged with a pressure of the fluid to be conducted and are designed such that, in a first pressure range of the fluid, the fluid entering the base body from the fluid actuator is discharged via one of the openings from the base body to the surroundings and, in a second pressure range of the fluid that is higher than the first pressure range, the fluid introduced into the base body is introduced into the fluid actuator.

Abstract: A neck support module for a headrest device of a vehicle seat comprises a frame and at least one inflatable pouch fixed to the frame.
