Hinged fitment for especially vehicle seat with adjustable backrest

摘要

The seat has a fixed link part (10), and the backrest has a movable link part (11). The two link parts are joined by a pivot shaft (12). A carrier arm (24) grips sloping wedge segments (22) forming a cam section (13) and supported on the bearing. The bearing periphery (26) in contact with the support parts of the wedge segments has a polygonal, almost circular, periphery formed by a number of adjacent facets (27).
