A pulsation module for an cushion assembly for a seat, such as a vehicle seat, including at least an air cushion and an air supply system for variably pressurizing the air cushions of the air cushion assembly with air. A respective supply line including a valve for pneumatically separating the air supply system from the air cushion leads from the air supply system to each air cushion, where a pulsation module is provided and configured to act upon each air cushion with a pulsation. The pulsation module includes a pneumatic element which is connected in a pressure-equalized manner to at least one supply line, and an actuating element for transmitting a mechanical motion to the pneumatic element for changing the volume of the pneumatic element in order to generate a pulsation.

Air cushion arrangement for a seat, for example a vehicle seat

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.

Air cushion arrangement

A valve includes a valve housing having first and second regions, at least one valve chamber configured to be pressurized with air and including an actuating element for opening and closing a valve opening and an actuator for actuating the actuating element, both arranged in the first region. A printed circuit board extends into each valve chamber and to electrically operate the actuator, the printed circuit board(s) being connected to a common main printed circuit board arranged in the second region. Each valve chamber is surrounded by boundary surfaces closing the valve chamber in a substantially gas-tight manner. An open space open to at least two oppositely disposed sides of the valve housing extends between at least two of the valve chambers, and a connecting member of the printed circuit boards extends through connecting openings of the boundary surfaces of adjacent valve chambers and the open space. A sealing material located in the open space encloses the connecting member and the connecting openings in a gas-tight manner at least in the direction of the oppositely disposed sides. A method of manufacturing such a valve includes manufacturing a conductor element including the printed circuit boards and the main printed circuit board; introducing the conductor element into the valve housing; and filling the open space at least in part with the sealing material from at least one side after the introducing step so that the sealing material seals the connecting member and the connecting openings in a gas-tight manner at least in the direction of the oppositely disposed sides.

Valve and method for manufacturing valve

Air cushion assembly for a seat, such as a vehicle seat, comprising at least an air cushion and an air supply system for variably pressurizing the air cushions of the air cushion assembly with air. A respective supply line comprising a shut-off valve leads from the air supply system to each air cushion, where a pulsation module is provided and configured to act upon each air cushion with a pulsation. The pulsation module comprises a pneumatic element which is connected in a pressure-equalized manner to at least one supply line, and an actuating element for transmitting a mechanical motion to the pneumatic element for changing the volume of the pneumatic element in order to generate a pulsation.

A massage device for a seat, in particular for a vehicle seat, is provided. The massage device includes at least one air cushion. The at least one air cushion has an air inlet so as to allow individual filling thereof with air via an air supply system. A vibration generating device is arranged between the air supply system and the air cushion and is in fluid communication with the air cushion so as to apply pressure vibrations to the air cushion. In addition, a seat including the massage device is also provided.
