Abstract: A method for activating personal protection means using at least one signal derived from an acceleration sensor. A forward displacement is determined from the signal, and the forward displacement is compared to at least one threshold value surface, which is set as a function of a velocity decrease and a deceleration. The personal protection means is activated as a function of the comparison.

Abstract: A method is described for generating at least one feature for an occupant protection system, which is determined from at least one basic feature and analyzed for generating a triggering signal for an occupant protection device, and a corresponding device. During normal operation, at least one short-term window integral is calculated from the at least one basic feature and used as a starting value for calculating a corresponding long-term integral when a starting condition for a crash operation obtains, the at least one long-term integral being made available to a following method as a feature for generating the triggering signal for the occupant protection system.

Abstract: In a method for activating occupant protection means as a function of at least one input quantity derived from at least one acceleration sensor, characteristic curves are calculated for the input quantities deceleration, forward displacement and/or speed reduction, which characteristic curves define at least one area in a quadrant of a coordinate system, which determines the deployment behavior of the occupant protection means.

Abstract: A device for triggering a second airbag stage as a function of at least one occupant variable and a crash severity, the crash severity being determined as a function of an impact velocity of occupants onto the airbag. In this context, the correlation between crash severity and impact velocity is formed on the basis of a standardized (standard) occupant.

Abstract: A method for triggering restraint devices in which at least one collision-indicating signal is generated. From the moment that a collision is detected, temporally defined crash phases are specified, and, for every crash phase, a crash type and a crash severity are determined from the signal. The appropriate restraint devices are triggered as a function of the crash severity and/or the crash type.
