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.

Arrangement and manipulation system, and method for manipulating the flow of a fluid

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.

Motor vehicle seat and motor vehicle seat system

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.

Functional apparatus for a vehicle seat, and correspondingly equipped seat system

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.

Vehicle seat

An electropneumatic switch arrangement having an actuation device plurality of pneumatic outlets for connection to fluid-fillable devices, and a pneumatic supply connection for connection to a pressure source, the actuation device being connected to a sealing device, the actuation device being designed in such a way that, when it is actuated, it opens a predefined flow path between the supply connection and at least one of the outlets and, in doing so, closes a current path for actuating the pressure source, characterized in that the sealing device is mechanically coupled to the actuation device in such a way that at least a part of the sealing device is moved, in particular displaced, by the actuation device when this is actuated, thereby opening a flow path between the supply connection and at least one of the outlets.

Electropneumatic switch arrangement

A valve device for controlling a fluid flow, in particular an air flow, having at least one inlet and at least two outlets, at least one of the outlets being fluidically connectable in each case to the inlet via a through-channel of at least one manipulable guide means. The through-channel of the guide means can be changed at least indirectly via a control fluid flow either with regard to at least a section of its internal cross section or can be rotated at least to a limited extent with regard to its orientation with respect to the outlets and the inlet can be rotated at least to a limited extent.

Valve device and valve system equipped therewith, and control device contained therein for fluid flow control

The present disclosure relates to a pneumatic adjusting device for adjusting a side wing of a vehicle seat from a default position to an actuation position, the adjusting device comprising: a two-armed lever having an outer lever arm for adjusting the side wing and an inner lever arm, an inflatable balloon device, e.g. balloon, for adjusting the inner for adjusting the arm, and mechanical spring means for adjusting the inner for adjusting the arm. Hereby, it is provided that, in the default position of the adjusting device, the balloon device is inflated, in the default position, the spring means is tensioned and biases the inner lever arm into the actuation position, and in the actuation position, the spring means compresses the balloon.

Pneumatic adjusting device for a side wing of a vehicle seat

A motor vehicle seat having a seat region, in particular a backrest or a seat part, wherein at least one fluid-filled hollow body connected to a first fluid inlet and outlet conduit is arranged in the seat region, wherein the at least one hollow body is part of a seat displacement device and/or a massage device and wherein the hollow body is supported by a support device also arranged in the seat region on its side facing away from an occupant sitting in the motor vehicle seat, characterized in that the support device in turn comprises at least one fluid-filled hollow support body which is arranged in the seat region and is spatially separated from the at least one hollow body, wherein the firmness of the seat and/or the strength of the massage application can additionally be adjusted by varying the filling of the hollow support body.

Motor vehicle seat

A cushion support for an at least partially resilient shaped part of a vehicle seat, in particular a back cushion support, having a support means designed for holding up and/or supporting the shaped part at least in regions and at least one expansion body designed for reversibly displacing at least a region of the shaped part, the cross section of which body can be changed by introducing and discharging a fluid. The support means is a mat arrangement which can be mounted in a frame of the vehicle seat and has two superimposed flexible mat layers, in particular formed by a textile, at least in regions, the expansion body being arranged between the mat layers.
