Presence detection system for an electrically adjustable furniture assembly and method of presence detection with an electrically adjustable furniture assembly

Abstract

A presence detection system for an electrically adjustable furniture assembly is disclosed. The presence detection system comprises at least one steady element and at least one movable element, articulatedly and/or slidably connected to the at least one steady element wherein at least one of the steady elements and/or at least one of the movable elements comprise an electrically conducting element. The presence detection system further comprises at least one actuator, arranged to electrically adjust at least one of the movable elements and at least one capacitance detecting unit, electrically connected to the at least one electrically conducting element, arranged to detect a capacitance value of the at least one electrically conducting element. The presence detection system also comprises at least one control unit, electrically connected to the at least one actuator and the at least one capacitance detecting unit, wherein the at least one control unit is arranged to provide a control signal to stop and/or reverse an adjusting movement at least in part when the at least one capacitance detecting unit detects a capacitance value of at least one of the electrically conducting elements higher than a predetermined capacitance threshold value.
