Monolithic vibrating rate gyro structure
First Claim
1. A monolithic rate gyro structure machined in a plate of material, comprising a fixed part, a resonator, a first mobile mass part fastened to a first end of said resonator, a second mobile mass part, first connecting means connecting said first mobile mass part to said second mobile mass part, and second connecting means connecting said second mobile mass part to said fixed part, characterized in that said second mobile mass part is not fastened to said resonator and is situated in the vicinity of a second end of the resonator, said first connecting means comprise first two flexible arms which extend along the whole of said resonator on respective opposite sides thereof and said second connecting means comprise second two flexible arms which extend along the first flexible arms and connect said second mobile mass part directly to said fixed part.
