Accelerometer

An accelerometer-comprising:

• a support;
• a mass that is movable relative to the sup-port;
• a translational guidance system of the mass relative to the support along a mobility axis of the mass relative to the support;
• an elastically-deformable part between the first and second portions of the deformable part;
• and
• a first lever pivoting about a first pivot point, the first lever being mechanically connected, on the one hand, to the mass and, on the other hand, to the first portion of the deformable part such that the movement of the mass relative to the support along the mobility axis causes the first lever to pivot about the first pivot point, wherein the accelerometer comprises a second lever pivoting about a second pivot point, the second lever being mechanically connected, on the one hand, to the support and, on the other hand, to the second portion of the deformable part, the first pivot point and the second pivot point being connected to one another via a bar such that during said movement of the mass relative to the sup-port, said first and second levers pivot relative to the bar and generate a movement of the first portion of the deformable part relative to the second portion of the deformable part.
