Thin type suspension seat

* Models that equip this component: Isuzu Elf (E.U. model), vehicles for Japan are expected to use these seats in the future as well. * The seat has a structure with dampers and wings, and the large suspension structure had its size and weight reduced through the use of urethane. As a result, the seat can be installed in small trucks. It also reduces costs as they have fewer components. * The seat received an award from the Monodzukuri Nippon Conference in 2016.

Active Headrest Mechanism
		The seating device reduces passenger whiplash injuries in rear-end collisions. The mechanism works during a collision by tilting the headrest while moving it up to lessen sudden change in the angle of the neck and torso, thereby reducing the strain on occupants. It has been introduced on Toyota models since fiscal 2007.
