Abstract:
1. Safety attachment device for an actuator connected by a first end part to a first connection point on a first piece and by a second end part to a second connection point on a second part, such that the actuation of the actuator causes a relative shift in position between said first and second part, said parts being connected to one another additionally by means of at least a reaction bar articulated by its respective ends to said parts, the actuator having sides and being situated on a first plane which extends between said connection points, and the reaction bar being situated on a second plane which extends between said ends of the reaction bar above said first plane; the safety attachment device comprising: a top part immobilized on the reaction bar; a first side arm and a second side arm which extend downward from said top part and enfold at least part of the sides of the actuator, both of said side arms are respectively crossed through by a first safety pin connected to a first side part of the actuator, and by a second safety pin connected to a second side part of the actuator opposite said first side part, each pin having a free end which emerges through a respective window; wherein each window is larger in size than the cross-section of the safety pin passing through it, such that the safety pin remains ready without coming into contact with edges of said window when the actuator is connected to said parts, said window having dimensions being large enough to prevent, when the safety pins are moved by way of operating movements of the actuator, said pins from coming into contact with edges of the windows, and each window is of a horizontal extension such that its side edges do not come into contact with said pin when a disconnection of the actuator from at least one of said parts takes place.
