DEFINITION

Classification: 280/5.515

Suspension stiffness for ride comfort (e.g., damping coefficient, spring rate):

(under subclass 5.5) Subject matter wherein the regulatable elastic means is caused to alter its elasticity property so

as to govern the extent of travel surface induced vibrational force experienced by a vehicle occupant.

SEE OR SEARCH THIS CLASS, SUBCLASS:

5.512, for an active suspension controlling lateral vehicle disposition and including suspension stiffness for ride comfort regulation.

6.157+, for a suspension arrangement including control means which establish riding or trim height of the vehicle suspension arrangement due to a static load for enabling proper running gear operation, which may or may not involve adjustment of suspension stiffness.

124.101+, for a mechanical hardware or structural assembly suspension arrangement including control means for preparatory adjustment of the extent of resilient, shock absorbing support provided.

124.108, for a mechanical hardware or structural assembly suspension arrangement specifically abating mechanically induced vibration.
