Benefits of technology

The patent describes a release lock and a deployment lock for a tubular cross member. The release lock is used to secure the tubular cross member in a stowed position, while the deployment lock is used to secure the tubular cross member in a deployed position. The technical effects of the invention include improved safety and reliability in achieving the desired position of the tubular cross member and improved protection of the deployable rollover protector shaft during transport and use.

Problems solved by technology

Motor vehicle rollover events present a challenge in the design of all classes of light motor vehicles, especially light trucks, such as pickups, sport utility vehicles, and vans.
Light trucks, especially sport utility vehicles, tend to experience tripped and untripped rollover events at a higher rate than other vehicles.

Abstract

A rollover mitigation device for a motor vehicle comprises a frame mounted to a roof assembly within which is disposed a transversely mounted deployable rollover protector shaft. The frame comprises a pair of lateral mounting rails mounted to the roof assembly and a tubular cross member extending between the pair of lateral mounting rails. The deployable rollover protector shaft is substantially disposed within the tubular cross member when in the stowed position and is actuated from the stowed position to a locked deployed position by a spring disposed within the tubular cross member. A controller actuates a release lock to release the deployable rollover protector shaft to the deployed position upon a sensor detecting a roll angle of the motor vehicle exceeding a predetermined value. A deployment lock restrains the deployable rollover protector shaft in the deployed position.

Description

FIELD OF THE INVENTION[0001]The present invention generally relates to an apparatus and method for mitigating a rollover event, particularly in the case of motor vehicles having a relatively high center of gravity, such as sport utility vehicles and, more particularly, to a spring loaded rollover protector shaft that is released when a critical rollover angle θ is exceeded.BACKGROUND OF THE INVENTION[0002]Motor vehicle rollover events present a challenge in the design of all classes of light motor vehicles, especially light trucks, such as pickups, sport utility vehicles, and vans. Light trucks, especially sport utility vehicles, tend to experience tripped and untripped rollover events at a higher rate than other vehicles. To avoid such rollover events, various vehicle stability control systems and driver assistance systems, such as lane departure warnings and tire pressure warnings, can assist the driver in avoiding and / or overcoming such an event. However, a practical active rollo...
