Vehicle seat for passenger motor vehicle
Abstract
The invention relates to a vehicle seat for a passenger car with active seat suspension. The seat structure (11) is movably mounted on a chassis of a passenger car via a swing frame (21), which is suspended by means of spring-damper pairs (22, 23). The active seat suspension (2) in this case has actuators (24), which are each connected to a spring-damper pair (22,23) for controlling the transmission behavior of the spring-damper pair. To allow a particularly sensitive control is provided that the active seat suspension (2) per controlled degree of freedom of the vehicle seat (Z, α) has a path sensor (27) which serves to accommodate the relative position of the swing frame (21) and vehicle chassis (16) ,
