Full Title
Suppression of vibrations in systems ( ; vehicle seat suspension devices B60N2/50; ); Means or arrangements for avoiding or reducing out-of-balance forces, e.g. due to motion ( ; testing static and dynamic balance of machines or structures G01M1/00) > Suppression of vibrations in rotating systems by making use of members moving with the system (by balancing F16F15/22 ; with flywheels acting variably or intermittently F16H ) > using elastic members or friction-damping members, e.g. between a rotating shaft and a gyratory mass mounted thereon ( , F16F15/16 take precedence) > the rotating system comprising two or more gyratory masses
