Class Information
Number: 280/5.515
Name: Land vehicles > Suspension modification enacted during travel (i.e., active suspension control) > Suspension stiffness for ride comfort (e.g., damping coefficient, spring rate)
Description: 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.
