Abstract
Blocking device for the backrest in child folding chairs, which is especially applicable to "scissors" type chairs, that is to say chairs in which the folding is carried out simultaneously in the longitudinal and transverse direction, and more specifically to chairs equipped with a postero- lower stiffening, established between the two lateral reinforcements of the chair, and a double compass established between the two sides of the backrest, essentially characterized because it consists of a trigger jointed hinged to one of the lower arms of this double compass, trigger that acts on a lug attached to a prolongation established in the other lower arm of double compass, beyond its point of articulation with the first arm, all in such a way that the aforementioned trigger blocks one arm on another, in a situation of extension of the chair, preventing the necessary tilting of the same for the folding of the double compass and the consequent retraction or of the sides of the backrest with respect to the average plane of the set.
