Abstract: The chair has a sub frame (1) set on the floor, a mechanism (2) set on the sub frame, a seat (3) set on the mechanism (2) and a backrest (7) attached to the mechanism (2). The backrest (7) exhibits a backrest frame (5), which supports an elastically deformable backrest part (6) with a back panel (62). The back panel (62) has a back part (60), to which a head restraint (61) is attached. The backrest (7) is capable of pivoting about a first pivot shaft (D1) from an essentially upright, neutral position to a reclined position displaced towards the rear. The movements of the seat (3) and the backrest (7) are synchronized with one another.

Abstract: A bench having a modular structure and comprising several seats, which rest on a longitudinal beam supported on at least two feet. An individual seat is formed by a seat panel which can be complemented by a backrest and lateral armrests, as well as tabletops. Benches of this kind can be used, for example, in airports and ferry terminals as well as long-distance train stations. The seat panels, backrests and tabletops are removably fixed to the longitudinal beam by the use of retaining plates. The feet and armrests are removably fixed directly to the longitudinal beam. The longitudinal beam extends along the full length of the bench, consists preferably of a double-walled aluminum hollow profile and has a regular, triangular cross-section with three longitudinal side faces as well as longitudinal grooves, situated in the area of the edges. The retaining plates are pieces of U-shaped rail sections cut to the required length.
