Abstract
A device for automatically controlling a headrest, includes a motor, a rotatable gear connected to the motor so as to provide rotating movement, a rack gear movably engaging with the rotatable gear to provide lineal movement, a rotator rotatably connected to the rack gear, a first connection mechanism for connecting the rack gear with the rotator, a second connection mechanism for connecting the rotator with the headrest, and a switch circuit for controlling rotation of the motor, whereby tilting of the headrest is automatically controlled by the switch circuit.
Claims20
A device for automatically controlling a headrest, the device comprising:
- a rotatable gear connected to a motor, the motor rotating the rotatable gear;
- a rack gear movably engaging with the rotating rotatable gear to provide lineal movement;
- a rotator rotatably connected to the rack gear, the rotator having a predetermined configuration such that the rotator occupies one position throughout an operation of the rotator;
- first connection means for connecting the rack gear with the rotator;
- second connection means for connecting the rotator with the headrest;
- and
- a switch circuit for controlling rotation of the motor,
- whereby tilting of the headrest is selectively controlled by the switch circuit.
A method of automatically controlling a headrest, the method comprising the steps of:
- rotating a motor to rotate a pinion gear;
- providing a rack gear movably engaging with the pinion gear to provide lineal movement;
- connecting the rack gear with a rotator using a link member;
- connecting the rotator with a plurality of stay rods supporting the headrest;
- and
- rotating the rotator by the lineal movement of the rack gear so as to selectively control tilting of the headrest, whereby the rotator occupies one position during the rotation of the rotator.
