0New technology spearheaded by a team of Windsor-based engineers could be on the horizon to prevent whiplash in rear-impact vehicle crashes.
The Windsor Machine Group, one of the industryâs leading suppliers of headrests, including those used in the Windsor-made Pacifica, last week sent a team to the Insurance Institute for Highway Safety in Virginia to test its True Active head restraint.Â
The head restraint uses radar sensors â the types used for backup assist and collision detection â  to optimally adjust in the second before a rear-end car crash, with the goal of minimizing impact on the occupantâs head and neck.
âWe thought that this would definitely be a great technology to prevent, or at least reduce, the potential of whiplash,â said Ahmad Farghawi, vice-president of engineering at Windsor Machine Group.
Farghawai said rear-end collisions are the most common type of car crash, and whiplash, an injury cased by the rapid back and forth movement of the head and neck, is the most common injury resulting from those crashes. Whiplash can cause chronic pain and lasting disabilities.
The problem with some anti-whiplash head rests is that they can be uncomfortable for drivers, Farghawi said, meaning theyâre not used effectively: only 14 per cent of Canadians adjust their headrest correctly â adding that industry professionals prefer to call them head restraints, not headrests, to recognize their importance to occupant safety.
âWhat weâre seeing is because of comfort, occupants do not want it to be in their way so they push it back as much as they can, and then they lower it downwards as much as they can,â Farghawi said.
âWhen you have a head restraint thatâs way too far from your neck, way too low from your neck, thatâs when youâre increasing the potential of whiplash occurring to you or your neck.â
Farghawi said the motorized head rest theyâre proposing is the best of both worlds: Comfort for most of the time passengers are in the vehicle, and added safety in the event of a crash.Â
True Active uses the existing sensors in a car to detect a possible crash, then signalling to the head restraint to position itself closer to the occupantâs head, supporting it on impact. The movement happens in less than a second in the event of a coming crash â and if no crash occurs, the head rest moves back.Â
The prototype was first developed in 2019, and showcased to Original Equipment Manufacturers in the following years before it was sent for testing at the Insurance Institute for Highway Safety (IIHS) last week.
The IIHS is an insurance industry-backed non-profit research group that measures safety features in cars. It helped back the Windsor Machine Group in testing the True Active head restraint by providing test vehicles.
âThese were actually vehicle tests, where one vehicle ran into the other and then deployed the head restraint prior to impact,â said Marcy Edwards, a senior research engineer at IIHS. âWhat weâll do is make a comparison and see if the dummy is able to detect a difference in that technology.
âThis is a fairly new area that weâre trying to evaluate and understand if they could be suitable for for real world occupants.â
The IIHS is now reviewing the data from the Windsor Machine Groupâs True Active test and the results are expected this fall.
From there the Windsor Machine Group will continue to show it to OEMs with the hopes the technology is adopted, Farghawi said, noting that all head restraints must be further tested in each individual vehicle.
âWeâre hoping once they see the results that (auto manufacturers) will be encouraged.â
