Item of seating furniture

Abstract

The invention relates to an item of seating furniture (1), in particular a working chair, which has a seat frame (5) and a carrying frame (2). The seat frame carries a seat surface (6). The item of seating furniture also has a frame (7) for a backrest (8). The frame (7) carries a pelvic support (9) which is located in the rear region of the seat surface (6) and is inclined with respect to a plane of the seat surface (6). A carrying element (11) of the carrying frame (2) extends into the region of the backrest (8) and carries a thrust bearing (13). The frame (7) is carried on the thrust bearing in a movable and pivotably moving way. The frame (7) is connected to the seat frame (5) on the tail end portion of the seat frame (5) through a joint (14). In this way, various ergonomically and orthopaedically beneficial sitting positions are achieved with low mechanical complexity.

Description

technical field [0001] The invention relates to a product of seating furniture having a load-bearing frame, which is movable relative to the load-bearing frame in sliding guides between a front working position and a rear rest position, and a seat frame The seating surface, the seating furniture product also has a frame for the backrest that is pivotally movable relative to the seating frame and is kinematically coupled to the seating frame. Background technique [0002] This seating furniture product is already commonly used in everyday life, especially in offices, and thus forms part of the state of the art due to a clear prior use. A key aspect of this seating furniture product is the ergonomically favorable transition between recessing and looping during seating. In particular, full back support is permitted. This is accomplished by the kinematic engagement of the seat surface to the backrest, which engagement is held on the transverse frame elements. The frame elemen...

Problems solved by technology

[0009] The previously mentioned types of previously known seating furniture products were found to have the disadvantage that although the seating surface can be moved and an ergonomically correct relative position between the seating surface and the backrest can be set, the seat The relative position of the individual partial areas of the surface, which can be automatically adapted to these different seating positions, has not been implemented or considered before in this respect.
