Concept & Functionality

Named HALO™, the structure is a High Attenuation Load Offset device. When attached to a production vehicle roof along with internal reinforcements, HALO reduces the speed and amount of crush in the roof structure, when the vehicle experiences a rollover crash. HALO is equipped to prevent catastrophic and fatal injuries to the occupants that might occur without it.

Life-Saving Features

  • The external roll hoop maintains the vehicle’s roll radius characteristic, allowing the vehicle body to roll more smoothly, minimizing forces on the occupants.

  • It also distributes the roof loads across the entire roof structure and underlying pillars to avoid a single point collapse.
     

  • The reinforcements minimize roof intrusion and speed at top of the structural pillars which keeps the roof up and away from the occupants.
