Abstract: The invention relates to a device comprising a body and a set of vibration absorbers mounted on the body, each absorber being movable relative to the body between a first position and a second position, each absorber being capable of oscillating relative to the body between its first and second positions, a first natural frequency being defined for each absorber, at least one absorber having a first natural frequency different from the first natural frequency of another absorber. Each absorber comprises at least one deformation part capable of deforming as the vibration absorber oscillates between its first position and its second position, the deformation part having at least two faces configured to rub against each other during the deformation of the deformation part.

Abstract: A rotation-guiding device includes a fixed support and a movable support able to rotate around the fixed support about an axis of rotation, wherein an interface between the fixed and movable supports includes a bearing to guide the movable support in rotation about the fixed support, a flexible dynamic seal providing seal-tightness between the fixed support and the movable support that is mounted between a friction track secured to one of said supports and a mechanical structure secured to the other support, and which includes a metal spring to provide the contact force for the seal between the friction track and the mechanical structure. The dynamic seal may be mounted parallel to the axis of rotation so that the contact force is exerted parallel to the axis of rotation.

Abstract: The invention relates to a rotation-guiding device which comprises a fixed support (11) and a movable support (12) which is able to rotate around the fixed support (11) about an axis of rotation (140), and an interface between the fixed (11) and movable (12) supports, which comprises: a bearing designed to guide the movable support (11) in its rotation about the fixed support (12), a flexible dynamic seal (1) designed to provide the seal-tightness between the fixed support (11) and the movable support (12), mounted between a friction track (4) secured to one of said supports (12 or 11) and a mechanical structure secured to the other support (11 or 12), and which includes a metal spring (5) intended to provide the contact force for the seal between the friction track and the mechanical structure. The dynamic seal (1) is mounted parallel to the axis of rotation (140), that is to say, so that the contact force is exerted parallel to the axis of rotation (140).
