Abstract
The invention concerns a pneumatic spring-mounted vehicle seat with an electronic control, which controls at least the air valves of the pneumatic spring as a function of the swing strokes of the rocker system. It is proposed that an accurate analogous-path and time-equal electrical pattern be produced with only one swing stroke sensor for the swing strokes, and this sensor is applied continually to the input of a microprocessor, and thus this pattern can be compared, during the operational state of the seat and in constant recurring program sequences, with preset and, as the case may be, changeable event theoretical values.
