Abstract

A synchronous mechanism for a seating furniture is provided having a seat surface support, a bending element whose length in the sagittal direction extends over a large part of a seat depth of the seat surface support and is coupled to the seat surface support for movement relative thereto. The synchronous mechanism has a backrest support mounted movably relative to the bending element for holding a backrest. The backrest support merges at the end into a pivot lever, coupled to the bending element at a pivot point to be pivotable about an axis of rotation transverse to the sagittal plane, a lever section of the pivot lever is in contact with the seat surface support at a bearing point, and, in the unloaded state of the seating furniture, the pivot point lies higher than the bearing point, as seen in the vertical direction.
