More Information
Summary:The invention relates to a damping system for a mobile mass (2) of a MEMS device (1), the system being capable of preventing direct contact between the mass (2) and a surface element (3) of the MEMS device (1), the damping system comprising: a mechanical bumper (4) positioned between the mass (2) and the surface element (3); a system (5) for locking/unlocking the bumper (4), which comprises one branch (51) oriented towards the bumper (4) having a blocking end (53) and a pin joint (54) capable of pivoting the branch (51), the locking/unlocking system (5) defining two subsequent positions of the mass (2).
