Abstract: 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.

Abstract: A process for increasing or reducing the internal pressure of at least one hollow body (HK—1, HK—2, HK—3) 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—1, HK—2, HK—3) and a supply line (VL) as well as (in the case pressure is increased) from the pressure which a pressure generator generates.

Abstract: The invention provides a method for operating a portable hand-held transmitter for a vehicle remote-control system in which a plurality of activation sequences control a plurality of assigned control functions in a normal operating mode, at least one control function being assigned to each prescribed activation sequence. The activation sequences differ in the manner and/or number of actuations of an activation mechanism of the portable transmitter. According to the invention the portable transmitter is switched over from the normal operating mode into a programming mode by means of a switch-over activation sequence which is carried out via the at least one activation mechanism. Assignments of the prescribed activation sequences and of the prescribed control functions can be changed as desired during the programming mode.

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, the amount is calculated. In one design of the invention, this amount depends upon the volumes of the hollow bodies (HK—1, HK—2, HK—3) and a supply line (VL) as well as (in the case pressure is increased) from the pressure which a pressure generator generates.

Abstract: The invention relates to a method for dynamic adaptation of the support of the body, in particular the lateral support, of a person seated on a vehicle seat, in which a measure of a current adaptation taking into account the current vehicle velocity is predicted and is set by an adaptation system which is integrated in the vehicle seat. In order to compensate for the inertia of the adaptation system which is inherent in the system, prediction of the adaptation is performed from stored data over the current road course, onto which data the current vehicle data are projected, and in that 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 travelled through, at least one adaptation presetting adapted thereto is achieved.

Abstract: An inflatable child seat includes at least two air chambers. The child seat is foldable when the at least two air chambers have been evacuated to form a suitcase like body. A releasable fastener is provided for fixing the child seat in its folded position. One half of the suitcase-like body forms an air chamber representing an inflatable cushion and the other half contains air chambers forming side parts, a backrest, a head restraint and a tray of the child seat.
