The issues of a person with reduced mobility, especially those of our elders, are known when it comes time to leave the house. The dilemma is: should I leave my home more than one floor because of the risk of falling down my stairs to live in a retirement home with high annual fees? Mechanical systems exist to answer this dilemma but they are expensive. We only have to think of chair lift escalators. However, these systems are not versatile when it comes time to install them. Moreover, many older people are denied such an installation because of a staircase too narrow for example. Even if the installation of these expensive chairlifts is carried out, 11 remains a non-negligible condition to be considered for the user but also for the Society and the public health: the use of a staircase in a safe and daily way is a undeniable advantage for cardiovascular health! The present invention is a compromise to all these aspects. The precise dimensions of a staircase or stairs are measured and there is installed a secure suspension system by a rescue type jacket, but stylized (see drawings subject to the present invention SKY HELPER). The user puts the jacket down the stairs. This is connected by a semi-rigid and vertical rubber rod, itself connected to a short rope-elastic above. The elastic rope is attached to a carriage that follows the user's unrestricted movement down the stairs, rolling on the base of a beam. This light steel or metal truss is located above and perhaps slightly offset from the center to fit any winding staircase. It is itself hung from the top by several anchors that will be fixed on the sides of the ceiling of the staircase on a solid part. If the user falls, he exposes his weight to the rod and the carriage which itself actuates a braking system as illustrated (it could also be a question of braking via a lever-clamping system on the beam). The user has the jacket at the top of the staircase for reuse and down later and so on. DESCRIPTION 1. The pres
