Commercial vehicle passenger seat - has electronic regulator controlling damping characteristic of pneumatic suspension springs for seat

摘要

The seat has a cushion carrier frame (3) supported for oscillation relative to a base (5) via pneumatic suspension springs (4), which are connected in an electronic regulation circuit for the vibration damping characteristic. The regulator has an actual value input coupled to a mean value stage, responding to a signal from a sensor (9) detecting the position of the carrier frame (3) relative to the base (5). Pref. the sensor signal is supplied to the mean value stage via a linearisation device. ADVANTAGE - Increased passenger comfort.
