Abstract
A method and a system in the classification of objects occupying a seat, in particular for the reliable control of the triggering of restraint systems in motor vehicles. Utilized are the dynamics of a person seated on the seat, based on the acceleration forces acting on the person. Using the variables of these forces and the force exerted on the seat cushion of the seat by the mass of the person and its change, there is a determination, as a redundant variable, the mass, the location of the center mass and other physical variables and these are used for the reliable classification.

10. A method for classifying an object occupying a seat, for a classification-dependent triggering of a restraint system in a motor vehicle, the method comprising:
-
determining first forces acting on the object in a horizontal plane as to their magnitude, and second forces exerted on the seat by the object in a direction that is vertical with respect to the horizontal plane as to their magnitude; and
determining at least a change over time of the forces acting on the object and at least physical variables of the object, the determining being done by calculating, from variables of the forces and a type of their change over time, and using these for the classifying. - View Dependent Claims (11, 12, 13, 14, 15)

16. A system for classifying an object occupying a seat, for a classification-dependent triggering of a restraint system in a motor vehicle having acceleration sensors in the vehicle for detecting dynamic forces acting on the object, comprising:
-
a first determining arrangement to determine first forces acting on the object in a horizontal plane as to their magnitude, and second forces exerted on the seat by the object in a direction that is vertical with respect to the horizontal plane as to their magnitude; and
a second determining arrangement to determine at least a change over time of the forces acting on the object and at least physical variables of the object, the determining being done by calculating, from variables of the forces and a type of their change over time, and using these for the classifying. - View Dependent Claims (17, 18, 19, 20)
