Abstract
An inertial sensor comprising a frame to which at least two seismic bodies are connected by resilient means so as to be movable in a suspension plane, and transducers to keep the seismic bodies vibrating and to determine a relative movement of the seismic bodies relative to one another, characterized in that the seismic bodies have a single shape and a single mass, and in that the seismic bodies comprise interlocking parts such that the seismic bodies are nested inside one another while being movable in the suspension plane relative to the other of the seismic bodies, with the seismic bodies having centers of gravity that coincide with one another. A method for manufacturing such a sensor.
