First Claim
1. A headrest apparatus comprising:
- a headrest main body provided at a top edge portion of a seatback against which the back of an occupant seated in a seat rests, with the headrest main body provided so as to be capable of moving in a vehicle front-rear direction;
a detection section provided at a vehicle front side of the headrest main body to detect contact between the head of an occupant seated in the seat and the headrest main body;
a moving section that moves the headrest main body in the vehicle front-rear direction; and
a controller that controls the moving section such that the headrest main body is moved forward until contact between the head of an occupant and the headrest main body is detected by the detection section, and, when contact between the head of an occupant and the headrest main body has been detected by the detection section, controls the moving section to move the headrest main body to a target position, wherein a movement amount of the headrest main body from an initial position thereof to the target position is given by subtracting a predetermined back-set setting value from a movement amount of the headrest main body from the initial position to a position where the headrest main body has contacted the head of the occupant.

8. A method of adjusting headrest position, the method comprising:
-
moving a headrest main body forward with a moving section, the headrest main body being provided at a top edge portion of a seatback against which the back of an occupant seated in a seat rests and being provided so as to be capable of moving in a vehicle front-rear direction; detecting contact between the head of an occupant seated in the seat and the headrest main body with a detection section provided at the vehicle front side of the headrest main body; and moving the headrest main body with a moving section to a target position, wherein a movement amount of the headrest main body from an initial position thereof to the target position is given by subtracting a predetermined back-set setting value from a movement amount of the headrest main body from the initial position to a position where the headrest main body has contacted the head of the occupant.

10. A headrest apparatus comprising:
-
a headrest main body provided at a top edge portion of a seatback which is configured to accommodate the back of an occupant seated in a seat; a contact detection unit provided at a vehicle front side of the headrest main body configured to detect a contact between the head of the occupant seated in the seat and the headrest main body; a driving mechanism configured to move the headrest main body to-and-fro in substantially vehicle front-rear directions; and a headrest control unit configured to control movement of the headrest main body, wherein the headrest control unit is configured to move the headrest main body toward the front in the vehicle front-rear direction until a contact between the head of the occupant and the headrest main body is detected by the contact detection unit and to move the headrest main body toward the rear in the vehicle front rear direction to a target position, wherein a movement amount of the headrest main body from an initial position thereof to the target position is given by subtracting a predetermined back-set setting value from a movement amount of the headrest main body from the initial position to a position where the headrest main body has contacted the head of the occupant.
