A method for dynamic adaptation of the support, in particular the lateral support, of a person seated on a vehicle seat includes using an adaptation system, which is integrated in the vehicle seat, to determine the adaptation taking into account the current vehicle velocity. In order to compensate for the inherent inertia of the adaptation system, prediction of the adaptation is performed from stored data over the current road course, onto which data the current vehicle data are projected. The adaptation system is actuated taking into account the adaptation time inherent in the system in such a way that, when the event requiring the adaptation occurs, preferably when a bend is traveled through, at least one adaptation presetting is achieved.

Method for adapting body support of a passenger seated in a vehicle seat in terms of vehicle movements dynamics and corresponding vehicle seat

A process for increasing or reducing the internal pressure of at least one hollow body (HK , HK , HK ) to a specified set internal pressure. The set internal pressure is adjusted so that several pressure-increasing steps or pressure-reducing steps are conducted successively until the internal pressure deviates from the set internal pressure at most by a specified tolerance. Each of these steps brings about a pressure increase or pressure reduction the amount of which is not larger than a specified upper limit. In this way, impairments of comfort owing to the rise in pressure or the reduction in pressure are especially avoided. The actual internal pressure is only measured at the beginning of the process. In one design of the invention, this amount depends upon the volumes of the hollow bodies (HK , HK , HK ) and a supply line (VL) as well as (in the case pressure is increased) from the pressure which a pressure generator generates.
