Seat chassis
11612246 · 2023-03-28 · ·

A seating furniture chassis comprises a seat surface frame, a backrest frame, two armrests, and a drive mechanism. The backrest frame is pivotable about a virtual pivot axis defined by two pivot points, wherein the backrest frame is fastened to the pivot points on the armrests. The drive mechanism is connected to the backrest frame by a translation mechanism. The drive mechanism is designed to trigger a translation of the translation mechanism, wherein the translation is converted into a pivoting movement of the backrest frame about the pivot axis. The backrest frame is connected below the pivot points to the seat surface frame so that during the pivoting movement the seat surface frame is moved translationally. The drive mechanism is arranged below a first lateral edge region of the seat surface frame.
