DEVICE TO PREVENT VEHICLE OVERTURNING Russian patent published in 2013 - IPC B62D49/08 B60K28/14 

FIELD: transport.

SUBSTANCE: invention relates to automotive industry, particularly, to appliances reducing probability of vehicle overturning in crosswise plane. Proposed device comprises storage battery, flexible transducer of vehicle angular position with pendulum and resistance bridge circuit of angular position conversion in electric signal, gas generator pyrocartridge with two air cylinders and bridge circuit. Transducer of vehicle angular position comprises two differentially interconnected coil springs. Said pendulum is connected with resistor slide that features variable resistance. Outputs of bridge circuit measuring diagonal are connected to comparator inputs. Comparator output is connected to contactor. Contactor terminals are connected to one of gas generator pyro cartridges with air cylinders depending upon direction of body turn angle vector in vehicle crosswise plane. Air cylinders are coupled with mechanical anti-overturn assemblies arranged at body roof perpendicular to vehicle lengthwise axis. Said assemblies comprise pistons extending rods to opposite directions with end spring retainers and thrusts.

EFFECT: higher passive safety.
