World-first secondary crash bags on way from Kia

  • Protection coming for a second impact
  • Happens in 30% of all road collisions
  • Kia on the ball chasing fewer impact injuries

SEOUL, South Korea – Future Kia road vehicles will have double crash-bag technology to improve protection of humans in a multi-impacy collision.

Automaker Kia, part of the Hyundai organisation, intends to improve crash-bag performance significantly during a multi-impact crash by developing and commercialising the world’s first multi-collision crash-bags.

Multi-collision crash? Well, such as when a primary impact is followed by a collision(s) with a second vehicle, a tree, or a power pylon – as happens, Kia says, ”in three out of every 10 crashes”.

‘Air bags’ (the world’s worst misnomer because they inflate with nitrogen, which is why The Corner doggedly calls them crash bags!) today merely cushion humans against the forces of a primary collision.

CALIBRATED TO REACT

Current bags help humans to survive an initial impact but can do nothing to prevent injury during a secondary impact – which can kill equally effectively).

The intended bags will be calibrated to react to that second impact by knowing occupants’ positions in the cabin during the first impact.

Multi-collision bags will deploy even faster when initial safety systems might not be effective, providing extra protection when drivers and passengers are most vulnerable.

Taesoo Chi, head of the Hyundai Motor Group’s Chassis Technology Centre, told The Corner in a media release: “We expect to improve significantly the protection of Kia drivers and their passengers.

“Well continue research ínto more-diverse crash situations thrugh our commitment to occupants’ protection.”

MEDIAN-LINE MAYHEM

Statistics from the US’ National Automotive Sampling System’s crashworthiness system say 30% of 56 000 crashes during 2000 to end 2012 in North America involved a ”multi-collision”.

The most common crashes follow a car crossing the median line (30.8%), followed by those caused by a sudden stop at a highway toll gate (13.5%), highway median strip collisions (8%), and sideswiping and collision with trees and electric poles (4%).

Such multi-collisions, Kia says, were analysed in multiple ways to improve bag performance and precision in a secondary collision.

Once commercialised, the system will appear in future Kia vehicles.
