The ratchets in this family feature a classic clock-type mechanism, with the gear rotation center aligned with the levers. In addition to the standard circular rotation, during opening they also perform a linear translational movement that increases the support surface while keeping the upholstery under tension, particularly in the case of headrests integrated with the backrest.
