Presence detection system for an electrically adjustable furniture arrangement and method of presence detection in an electrically adjustable furniture arrangement

摘要

A presence detection system for an electrically adjustable furniture assembly is disclosed. The presence detection system comprises at least one fixed element (3) and at least one movable element (5) hingedly and / or slidably connected to the at least one fixed element (3), at least one of the fixed elements (3) and / or at least one of the movable elements (5) comprises an electrically conductive element. The presence detection system further comprises at least one actuator configured to electrically adjust at least one of the movable elements (3) and at least one capacitance sensing unit electrically connected to the one at least one electrically conductive element is arranged, which is designed to detect a capacitance value of the at least one electrically conductive element. The presence detection system also includes at least one control unit electrically connected to the at least one actuator and the at least one capacitance sensing unit, wherein the at least one control unit is configured to provide a control signal to at least partially stop and / or reverse an adjustment movement when the at least one capacitance detection unit detects a higher capacitance value of at least one of the electrically conductive elements than a predetermined capacitance limit value.
