Seat element

A seat element comprising:

• a carrier frame, and
• supporting surfaces,
• wherein the carrier frame comprises a left-hand sidepiece and a right-hand sidepiece,
• wherein the supporting surfaces are configured as a seat surface and a back surface,
• wherein at least one supporting surface, of the supporting surfaces, comprises a cover element,
• wherein the cover element comprises a fabric and is supported on the left-hand sidepiece and on the right-hand sidepiece of the carrier frame,
• wherein the seat element comprises actuators,
• wherein the cover element is supported on the left-hand sidepiece and/or on the right-hand sidepiece by at least one actuator, of the actuators, such that a level of tensioning to which the fabric of the cover 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 cover element is subjected when the at least one actuator has been deactivated,
• wherein the at least one actuator comprises a clamping body,
• wherein the cover element is either directly connected to the clamping body or is indirectly connected by an interposition of a force transmission element which is configured as a clamping slide, and
• wherein at least one of:
• the at least one actuator pushes with a compressive force onto the cover element for clamping the cover element, or
• the at least one actuator pulls with a tensile force on the cover element.

A seat element comprising:

• a carrier frame, and
• supporting surfaces,
• wherein the carrier frame comprises a left-hand sidepiece and a right-hand sidepiece,
• wherein the supporting surfaces are configured as a seat surface and a back surface,
• wherein at least one supporting surface, of the supporting surfaces, comprises a cover element,
• wherein the cover element comprises a fabric and is supported on the left-hand sidepiece and on the right-hand sidepiece of the carrier frame,
• wherein the seat element comprises actuators,
• wherein the cover element is supported on the left-hand sidepiece and/or on the right-hand sidepiece by at least one actuator, of the actuators, such that a level of tensioning to which the fabric of the cover 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 cover element is subjected when the at least one actuator has been deactivated, and
• wherein;
• at least one actuator, of the actuators, comprises a resilient hollow body which can be changed in terms of shape by supplying or draining off a fluid, and/or
• at least one actuator, of the actuators, comprises a single eccentric or a double eccentric which can be adjusted by hand and/or automatically, and/or
• at least one actuator, of the actuators, comprises a spindle which can be adjusted by hand or automatically.

• wherein the carrier frame comprises a left-hand sidepiece and a right-hand sidepiece,
• wherein the supporting surfaces are configured as a seat surface and a back surface,
• wherein at least one supporting surface, of the supporting surfaces, comprises a cover element,
• wherein the cover element comprises a fabric and is supported on the left-hand sidepiece and on the right-hand sidepiece of the carrier frame,
• wherein the seat element comprises actuators,
• wherein the cover element is supported on the left-hand sidepiece and/or on the right-hand sidepiece by at least one actuator, of the actuators, such that a level of tensioning to which the fabric of the cover 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 cover element is subjected when the at least one actuator has been deactivated,
• wherein the at least one actuator, when deactivated, is configured to position the cover element in a first position relative to the carrier frame,
• wherein at least one actuator, when activated, is configured to position the cover element in a second position relative to the carrier frame, and
• wherein the cover element is lifted further from the carrier frame in the second position than in the first position.
