Abstract
A device for increasing the resistance and durability of an articulation mechanism, usable to control the position of a seat, includes a fixed flange rigidly connected with the seat and a movable flange rigidly connected with the movable part of the seat; these two flanges are rotatable with respect to each other by a mechanical assembly with a locking by suitable mechanism. The fixed flange carries, close to its periphery, a fine toothing that is not normally in contact with a fine continuous circular toothing provided on a peripheral circular element of the movable flange, these fine continuous circular toothings coming in contact with each other along a given length when the articulation mechanism is distorted as a consequence of a sudden shock.
