Abstract
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. 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.

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.
An assembly comprising:
- a first part and a second part;
- a disconnectable coupling system provided with a mechanical fuse which secures together the first part and the second part according to an axis of movement up to a breaking threshold;
- the mechanical fuse being broken upon the breaking threshold being reached in response to a movement of the first part with respect to the second part according to the axis of movement while the second part is seized;
- a single-use friction brake interposed between the first part and the second part, the friction brake braking the movement of the first part with respect to the second part after the mechanical fuse has broken,
- the friction brake including a stud, the stud being arranged facing a wall of the first part and being arranged within a housing of the second part, the stud being trapped in the housing of the second part prior to the mechanical fuse being broken, the stud and the wall of the first part being movable relative to each other after the mechanical fuse has broken, and
- the wall of the first part, following the movement of the first part with respect to the second part after the mechanical fuse has broken, applying a force to the stud that moves the stud in translation relative to the housing of the second part whereby friction of the stud against the housing of the second part brakes the movement of the first part with respect to the second part.
