Abstract: The construction kit consisting of wall elements (1,2) and connectors (3,3?) to be inserted therebetween is designed in order to erect room dividers. The wall elements (1,2) are produced by compressing fiber material and have at least one connecting flank (100,20) which is systematically provided with contours (105,25). The connectors (3,3?) are designed as a profiled rail on which there is at least one connection (30,30?) which has systematically arranged mating contours (35,35?). The contours (105,25) on the wall elements (1,2) can be brought into form-fitting engagement with the mating contours (35,35?) on the connectors (3,3?). The fiber material used for producing the wall elements (1,2) is a compressed polyester nonwoven fabric or a mixture of natural and synthetic fibers. The connector (3,3?) is an extruded profile, preferably made of aluminum.

Abstract: The chair is of the type with mutually synchronous adjustment between back inclination and seat inclination, namely via a region between a respective zero position of back inclination (R0) and seat inclination (S0) and a respective maximum back inclination and seat inclination. The chair has a substructure (1) which is intended for placing on the floor and on which a base (2) is fastened rigidly. A seat support (6) which has a seat region and a back region is connected to the base (2). Furthermore, the chair includes two backrest bows (3) which are deflectable differently with respect to each other and are fastened on one side to the base (2) and on the other side to the back region of the seat support (6). The two backrest bows (3) are coupled independently of each other to the base (2) on a stationary first axis of rotation (D1). The seat region of the seat support (6) is coupled to the base (2) on a stationary second axis of rotation (D2).
