A regulatable suspension system for an active chassis of a motor vehicle has at least two actuators which are capable of being set via actuating signals in order to influence the relative movement between a wheel of the motor vehicle and the vehicle body. A control unit is provided for generating the actuating signals as a function of input signals representing vehicle state variables. Actuating movements that can be applied to the wheel by the actuators and acting on the wheel have parallel direction components. In the event of a fault, if one actuator is defective, actuating signals coupling the actuators can be generated in such a way that a control function assigned to the defective actuator can be set via an intact actuator.

A safety arrangement for an adjusting installation of a seat adapted to be actuated manually or programmed, especially of a vehicle seat, with adjusting motors and with an electronic circuit which gives priority to the manual seat adjustment over a programmed seat adjustment, which, in case of a relay or adjusting motor defect, opens up the corresponding circuit, which in case of a simultaneous actuation of several position buttons, interrupts a programmed seat adjustment and which after interruption of the energy supply permits a programmed seat adjustment only after renewed storage of a seat position.
