Assembly provided with a disconnectable coupling system having a mechanical fuse and a friction brake

An assembly comprising a first part and a second part, the assembly comprising a disconnectable coupling system provided with a mechanical fuse for securing the first part and the second part according to an axis of movement up to a breaking threshold,

• wherein the assembly comprises at least one single-use friction brake interposed between the first part and the second part, the friction brake braking a movement of the first part with respect to the second part after the mechanical fuse has broken, the friction brake comprising a stud that is trapped, when in a rest position, in a housing of the second part before the break, the stud being arranged facing a wall of the first part, the stud and the wall being able to move relative to each other following the break, the wall applying a force to the stud, following the break and the movement, that moves the stud in translation relative to the second part.
