A dynamic ergonomic surface system for use in a motor vehicle includes an ergonomic surface that is inlayed in a surrounding surface and transitions between states, including: a neutral state in which the ergonomic surface is consistent with the surrounding surface, and at least one ergonomic support state in which the ergonomic surface provides ergonomic support for a user operating an input device. The dynamic ergonomic surface system also includes a sensor system that detects events triggering the transition between states, and a controller that controls the ergonomic surface to transition between the states in response to the detected events.

A pneumatic solenoid valve includes a fluid connector, a magnet coil which extends along a coil axis, a yoke arranged on the magnet coil, and an armature movable relative to the yoke and which extends along an armature axis and which is formed for opening and closing the fluid connector. The armature can assume three different switching positions. In the first switching position, the armature and coil axes are arranged parallel to one another and the armature completely closes off the fluid connector. In the second switching position, the armature is rotated about an axis of rotation, such that the armature axis and the coil axis assume an angle with respect to one another and the armature partially opens the fluid connector. In the third switching position, the armature is in a state axially displaced in relation to the first switching position, such that the fluid connector is completely open.

A pump assembly includes a pneumatic pump with a pump body having a discharge passage. The pump is operable to discharge compressed air through the discharge passage. The pump assembly also includes a cap adjacent the pump body and at least partially enclosing a first volume in communication with the discharge passage, and a casing at least partially surrounding the pump. The pump assembly further includes a second volume defined between the casing and the cap, the second volume in fluid communication with the first volume via an opening in the cap, and a casing outlet in fluid communication with the second volume. The pump assembly is configured such that the compressed air flows through the first volume and the second volume before being discharged from the casing through the casing outlet.

An air pump device includes an electric pump unit including a pump mechanism and a motor configured to drive the pump mechanism, a case housing the electric pump unit, and a vibration-proof member interposed between the electric pump unit and the case. The vibration-proof member is a plate-shaped member made of an elastic resin material and is wound around the electric pump unit to wrap the electric pump unit therein. A part of the vibration-proof member is sandwiched between the electric pump unit and one of facing surfaces that are inner surfaces of the case and face each other inside the case. Another part of the vibration-proof member is sandwiched between the electric pump unit and the other one of the facing surfaces.

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.

An articulation assembly for a vehicle seat includes a planar engagement surface. An inflatable member is operably coupled to the planar engagement surface. The inflatable member includes a plurality of polyhedral bodies that are configured to be formed via additive manufacturing. Each of the polyhedral bodies has a foldable portion that defines crease lines. A plurality of elastomeric members are disposed on each crease line. A planar base includes a port fluidly coupled to the polyhedral bodies. A manifold is fluidly coupled to the port of the planar base and is configured to translate fluid through the port to the polyhedral bodies.

An air cushion arrangement installable in an interior of a seat having a seat surface may have at least one air cushion and an air supply system for variably supplying the at least one air cushion with air, wherein at least one air cushion is assigned a pulsation generator, the at least one air cushion being non-fluidically connected to the pulsation generator. The air cushion and the pulsation generator are configured to generate a pulsation in a direction of the seat surface of the seat (e.g., if the air cushion arrangement were installed in the interior of the seat). A seat assembly including such an air cushion arrangement is also disclosed.

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.

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.
