SSS0508 Front-seat Active Head Restraints GUID-387F51B4-7CEA-4F79-A0BF-23E93E24350D The Active Head Restraint moves forward utilizing the force that the seatback receives from the occupant in a rear-end collision. The movement of the head restraint helps support the occupant's head by reducing its backward movement and helping absorb some of the forces that may lead to whiplash-type injuries. Active Head Restraints are effective for collisions at low to medium speeds in which it is said that whiplash injury occurs most. Active Head Restraints operate only in certain rear-end collisions. After the collision, the head restraints return to their original positions. 1-8 Safety - Seats, seat belts and supplemental restraint system
