Abstract
The present invention involves a method of providing head support with a movable headrest of a vehicle seat to a vehicle occupant head during impact of the vehicle. The method includes moving the headrest toward the head of the occupant in a first manner upon impact of the vehicle and moving the headrest toward the head of the occupant in a second manner different from the first manner. The first and second manners may include first and second velocities and first and second trajectories of the headrest.
Claims16
A method of providing head support with a movable headrest of a vehicle seat to a vehicle occupant head during impact of the vehicle, the method comprising:
- moving the headrest toward the head of the occupant in a first manner upon impact of the vehicle;
- and
- moving the headrest toward the head of the occupant in a second manner different from the first manner wherein the first manner in which the headrest is moved is along a first trajectory of the headrest and the second manner in which the headrest is moved is along a second trajectory of the headrest different from the first trajectory.
A method of providing head support with a movable headrest of a vehicle seat to a vehicle occupant head during impact of the vehicle, the method comprising:
- moving the headrest toward the head of the occupant along a first trajectory and at a first forward velocity upon impact of the vehicle;
- moving the headrest toward the head of the occupant along a second trajectory and at a second forward velocity before the head of the occupant contacts the headrest, one of the first trajectory and first forward velocity being different from one of the second trajectory and second forward velocity respectively.
