Armrest with adjustable angle

The armrest has a tilt angle adjustment device comprising axles with two cones, where the axles are attached at a support (1). Smaller and larger diameter of the cones are adjusted at ends of the axles and at a center part of the axles, respectively. A carrier (2) is fixedly connected with a sleeve (3) or sleeve cladding. A control device controls shift rotating motion of toothed rings based on pivoting movement and/or position of the carrier. The control device comprises functional parts, which are arranged on ends of the axles between ends of the toothed rings and the support.
