Method for adapting body support of a passenger seated in a vehicle seat in terms of vehicle movements dynamics and corresponding vehicle seat
First Claim
1. Method for dynamic adaptation of the support of the body of a person seated on a vehicle seat, the method comprising:
- predicting and setting, by an adaptation system which is integrated in the vehicle seat, desired adaptation at a point on a curved road before the vehicle arrives at the point taking into account current vehicle velocity from stored road data;
actuating the adaptation system taking into account the adaptation time inherent in the system, whereby when an event requiring the adaptation occurs, at least one adaptation presetting adapted thereto is achieved.

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.

10. Vehicle seat comprising:
-
a seat part, a backrest, an adaptation system for adapting body support of a person seated on the vehicle seat, the adaptation system including air cushions which are integrated at least in side bulges of the seat part and/or backrest, and a compressed air regulating device for adjusting the air pressure in the air cushions, a control unit which has a control computer and is connected to the compressed air regulating device and generates, from a lateral acceleration value fed to the control unit, a control signal for setting a filling pressure by the pressure regulating device, a sensor connected to the control unit for measuring the vehicle velocity, a prediction device for predicting the lateral acceleration expected in a current curve, and a prediction filter which applies the predicted lateral acceleration to the control unit taking into account the filling pressure-dependent filling times of the adaptation system. - View Dependent Claims (11, 12, 13)

14. A method for dynamic adaptation of vehicle seat support, the method comprising:
-
predicting a desired seat support at a point on a curved road section on the basis of vehicle velocity from stored road data for a road which the vehicle is traveling on before the vehicle arrives at the point on the curved road, and actuating an adaptation system to provide a seat support based on the predicted desired seat support when the vehicle arrives at the point on the curved road section, taking into account delays in the adaptation system. - View Dependent Claims (15, 16, 17, 18, 19, 20)

21. A vehicle seat system comprising:
-
a vehicle seat;
an adaptation system for adapting the vehicle seat for body support, the adaptation system including, air cushions which are integrated in the vehicle seat, and a compressed air regulating device for adjusting air pressure in the air cushions;
a control unit including a control computer, the control unit being connected to the compressed air regulating device for setting air cushion pressure;
a vehicle speed sensor, the vehicle speed sensor being connected to the control unit;
