Abstract: The invention relates to a lumbar support (1) for a chair with a backrest comprising backrest carriers (7) which are pivotable independently of each other, wherein the lumbar support comprises support regions (10a, 10b) which are each mounted on a spring element (2). The spring action of each spring element (2) is individually adjustable. In this arrangement, the spring elements (2) are arranged on a carrier (5), which can be articulated to the backrest carriers (7) of the backrest of the chair, which are pivotable independently of each other. The invention further relates to a chair with a backrest, which is formed from backrest carriers (7) which are pivotable independently of each other and which also comprises the aforementioned lumbar support (1). In this case, the lumbar support (1) is articulated to the backrest carriers (7) which are pivotable independently of each other.

Abstract: An item of seating furniture employs a seat depth adjustment, in which the seat is mounted displaceably relative to a backrest frame. A pivotable lower backrest frame is mounted on the backrest frame. The lower backrest frame is connected to the rear part of the seat. The displaceable seat thereby remains connected to the backrest, and a horizontal gap does not arise between the backrest and seat, which horizontal gap could impair the seating comfort and interfere in the overall appearance of the item of seating furniture. The seat depth adjustment is in particular also suitable for use with synchronous mechanisms.
