PROBLEM TO BE SOLVED: To provide a vehicle sheet capable of reducing whiplash injury occurring on a seating person.SOLUTION: A vehicle sheet is provided with a headrest 4 having a pad 40. An insert material 46 is provided on a portion which receives a head part of a seating person, of the pad 40. The insert material 46 is formed with rigid urethane which has a higher hardness than the pad. Hardness of the rigid urethane can prevent the head part of the seating person from being sunk to an inner part of the headrest 4 by inertia force actuating on the seating person, thereafter, when the head part of the seating person is brought into such a state as to close a gap for the headrest 4, it can be permitted that the head part of the seating person is sunk into the inner part of the headrest 4 by the inertia force subsequently actuating on the seating person. |
