The Japanese automobile giant, Toyota has developed a new head restraint system which reduces stress on the neck during low-speed rear impacts, named as Active Headrest.
Besides, a sensor built into the seat’s backrest recognizes when the occupant’s lower back presses against the backrest, thus triggering the upper unit to activate the head restraint. The head restraint activates diagonally 30mm upwards and 25mm forwards to quickly catch the back of the head. This can reduce severity of whiplash injury by 10-20%.
Hopefully, we can see this amazing system in every vehicles in the near future!
