1. System for a vehicle, comprising:
- a vehicle seat which comprises a seat part and a backrest defining an accommodating space intended to accommodate an occupant having a mass, an electromagnetic field measuring device comprising at least one pair of electrodes arranged in the seat part, to generate an electromagnetic field in said accommodating space and to measure at least one value associated with an electromagnetic characteristic of propagation of said electromagnetic field in the accommodating space, at least one actuator device having several modes of operation, said actuator device being adapted to be activated in several different ways corresponding respectively to the several modes of operation, and an operating device designed to activate the actuator device selectively according to one of its several modes of operation depending on said value measured by the measuring device, wherein the system comprises at least one central electronic unit designed to measure said mass of the occupant on the basis of said at least one value and to transmit a mass parameter representing said mass to said memory of the operating device, and wherein the operating device has a memory in which said mass parameter is stored, said operating device being designed to choose the mode of operation of the actuator device according to said mass parameter.
