A method and an apparatus determine the frequency or the period of the natural characteristic oscillation of a vehicle, and therefrom determine the mass of the vehicle and provide a warning if a dangerous oscillation condition exists which could lead to a tipping or rollover of the vehicle. The evaluation is carried out while the vehicle is driving. The apparatus includes a sensor such as a rotation rate sensor, a timer, an evaluating unit, and a warning unit. The method involves measuring the time interval between two characteristic features of the oscillation measured by the sensor, such as zero crossings, minimum points or maximum points of the angular velocity of the oscillation, and then calculating the period and / or the frequency of the oscillation from the measured time interval. Then the moment of inertia and / or the mass of the vehicle can be determined from the period or frequency. Also, if the period or frequency is out of a safe range, a warning is triggered to indicate to the driver of the vehicle that a rollover danger exists.

A seating unit that includes a linkage mechanism adapted to adjust between closed, extended, and reclined positions is provided. The linkage mechanism includes a seat-mounting plate mounted to a footrest assembly, a back-mounting link and a rear bellcrank both rotatably coupled to the seat-mounting plate, an activator bar that controls a footrest drive link, and a linear actuator for carrying out automated adjustment of the linkage assembly. In operation, a stroke in a first phase of the linear actuator generates a torque on the activator bar. The footrest drive link converts the torque into a laterally-directed force that pushes the footrest assembly into the extended position. A stroke in the second phase acts to push the activator bar forward and translate the seat-mounting plate forward at a consistent inclination angle. The forward translation causes the rear bellcrank to rotate, thereby biasing the back-mounting link rearward into the reclined position.
