Abstract

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.
