Whiplash Injury System

Our Whiplash Injury Lessening system (WIL) is designed to help minimise whiplash injuries to the neck.

Whiplash injury occurs when the head and torso move in opposite ways during a rear-end collision.

So that the seatback and headrest simultaneously cushion the occupant's head and torso during impact, we re-assessed the positioning of the seatback frame and the headrest. We also improved seat frame rigidity, in the design of our WIL seatback system.
