Seat element

A seat element comprising:

• a carrier frame,
• one or more actuators, and
• supporting surfaces,
• wherein the carrier frame comprises at least one left-hand side member and a right-hand side member,
• wherein the supporting surfaces comprise a seat surface and/or a backrest surface,
• wherein at least one supporting surface of the supporting surfaces comprises a covering element,
• wherein the covering element comprises a fabric and is stretch-mounted on the at least one left-hand side member and on the right-hand side member of the carrier frame,
• wherein the covering element comprises tension elements,
• wherein each tension element of the tension elements is subjected to pulling action by at least one actuator of the one or more actuators such that a level of tensioning to which the fabric of the covering element is subjected when the at least one actuator has been activated is greater than a level of tensioning to which the fabric of the covering element is subjected when the at least one actuator has been deactivated,
• wherein at least one tension element of the tension elements is arranged on a front surface of the covering element and the at least one actuator acts on a rear surface of the covering element, the rear surface being located opposite the front surface, in order to subject the at least one tension element to the pulling action,
• wherein the at least one actuator and the at least one tension element are connected to one another through the covering element, and
• wherein the at least one tension element comprises at least one fastening point that engages through the covering element.
