Active Head Restraint
The active head restraint system is designed so that the headrest
instantaneously moves towards the front upper direction by utiliz-
ing the force at the seatback during a rear-end collision.
As a result, the occupant's head is protected from being
overextended, reducing the chance for neck injury as much as
possible.
Seat with active head restraint have the labels shown in figures at
left.
OPERATION OUTLINE
When the seatback receives a sharp backward force during a rear-
end collision, the input plate moves with the link rotating center as
a pivot. The headrest will then move towards the front upper direc-
tion with the center of the sliding roller as a pivot.
As the backward force on the seatback is eliminated, spring tension
returns the headrest to its original position.
