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. |
