and in that one of the first connecting portion and the second connecting portion is formed by a rail, extending in a vertical direction, having a trapezoidal section in a horizontal plane, and the other one of the first connecting portion and second connecting portion is formed by an elongated housing mating said rail, wherein the rail may slide in the vertical direction,

wherein the blocking elements include;

at least one male element borne by one from among the attachment member and the lateral fixed support, movable between a deployed position and a retracted position, and at least one first elastic member for returning the male element towards the deployed position,

at least one fixed female element, mating the male element, borne by the other one from among the attachment member and the lateral fixed support, each male element being found facing the corresponding female element when the attachment member is added onto the lateral fixed support at the end of the predefined travel of the first connecting portion with respect to the second connecting portion,

and wherein each male element is formed by a hook borne by a rotating axis.

9. The comfort device according to claim 8, wherein:
