Abstract
A system for adjusting the height of automobile vehicle seats having an arm of the mechanism which is hinged on a support around a hinge shaft. It is formed of two elements connected by a pivot and at least a connecting member with a predetermined rupture load. One of the elements includes a main set of teeth in the form of an arc of a circle centred on the hinge shaft and the other element includes a secondary set of teeth with same centre. A pinion located between the two sets of teeth meshes only with the main set of teeth when the two elements of the arm are securely attached. In case of an excessive load on the arm, the connection is broken and the secondary set of teeth meshes with the pinion subsequent to the relative pivoting of the two elements and prevents the rotation of the pinion.
