Abstract

A vehicle anti-rollover system including at least one gas generator which discharges a gas flow sideways, to an atmosphere where the vehicle is rolling over under a rollover force of the vehicle, when the gas generator is activated or actuated during a vehicle rollover. A predetermined force of the gas flow produces a reactive force applied to the vehicle. The rollover force of the vehicle is directed sideways where the vehicle is rolling over, while the reactive force of the gas flow of the anti-rollover system is directed sideways in an opposite direction. Thus, the reactive force of the gas flow reduces the rollover force and minimizes the risk of a rollover crash or rolling over and serious vehicle occupant'"'"'s injuries. In a vehicle unstable or rollover situation to avoid a vehicle rolling over, the system also allows the vehicle occupant to actuate the gas generator and to stabilize the vehicle almost instantly.

Claims

1. A vehicle anti-rollover system adapted to exclude a direct contact in an activated condition between its members and a road surface on the side where said vehicle is rolling over in a rollover crash, comprising:

at least one gas generator attached to a vehicle, adapted to produce flow of gas;

at least one double guide device or double nozzle with hingedly attached covers to discharge a flow of said gas into an atmosphere, said covers and hinges adapted to swing open and direct said gas flow in a sideways direction of said vehicle and toward said road surface, where said vehicle is rolling over under a rollover force of said vehicle, when a vehicle'"'"'s degree of tilt exceeds a predetermined angle and activates said at least one gas generator;

said gas flow being adapted to generate a force of reaction, applied to said vehicle and directed sideways in an opposite direction to said rollover force of said vehicle, thereby reducing said rollover force of said vehicle,

said force of reaction being adapted to return said vehicle to a former conditions which was prior to a rollover situation,

whereby said reduced roller force minimizes the risk of a rollover crash and serious vehicle occupant'"'"'s injuries.

2. A vehicle anti-rollover system adapted to exclude a direct contact in an actuated condition between its members and a road surface on the side where said vehicle is rolling over in a rollover crash, comprising:

at least one gas generator with at least one double guide device or double nozzle connected to vehicle top above center of gravity;

covers with hinges adapted to discharge a flow of gas laterally into an atmosphere outside said vehicle through said double guide device or double nozzle, in a direction of a rollover force of said vehicle and toward said road surface on the side where said vehicle is rolling over under said rollover force of said vehicle, when said at least one gas generator is actuated during a vehicle rollover;

said gas flow being adapted to produce a force applied to said vehicle and directed sideways in an opposite direction to said rollover force of said vehicle, thereby reducing said rollover force of said vehicle,

said produced force being adapted to return said vehicle to a previous condition which was prior to a rollover situation, whereby said reduced rollover force minimizes the risk of a rollover crash and serious vehicle occupant'"'"'s injuries.

3. A vehicle anti-rollover system designed to exclude a direct contact between its members and a road surface in an actuated condition on the side where said vehicle is rolling over in a rollover crash, comprising:

at least one gas generator adapted to generate gas with at least one double guide device or double nozzle connected to the vehicle top;

hinged covers adapted to expel a flow of said gas into an atmosphere, sideways of said vehicle and toward said road surface, on the side where said vehicle is rolling over under a predetermined rollover force of said vehicle, when said force of a rollover acts on said vehicle and actuates said at least one gas generator;

said gas flow being adapted to produce a force which is applied to said vehicle and directed sideways in an opposite direction to said rollover force of said vehicle, thereby reducing said rollover force of said vehicle,

said produced force being adapted to restore said vehicle to a previous condition which was before a rollover situation, whereby said produced force stabilizes said vehicle and minimizes the risk of a rollover crash and serious vehicle occupant'"'"'s injuries.
