Abstract

The invention discloses an adjusting device of a seat headrest. The device comprises a holding bar, a reset spring and a pulling rope group. According to the invention, the adjusting device of the seat headrest is provided with a pulling rope group and holding bars, wherein the pulling rope group can drive the holding bars to rotate; in an initial state, the reset spring is in a stretched state, a first pulling rope drives a first holding bar and a second holding bar to compact a first headrest adjusting bar together, and a second pulling rope drives a third holding bar and a fourth holding bar to compact a second headrest adjusting bar together; and after a pulling rope power mechanism supplies power, a third pulling rope drives the first pulling rope and the second pulling rope to move respectively so that the first pulling rope drives the first holding bar and the second holding bar to rotate and gradually separate from the first headrest adjusting bar and the second pulling rope drives the third holding bar and the fourth holding bar to rotate and gradually separate from the second headrest adjusting bar; and therefore, the headrest position can be adjusted as necessary, and the needs of different drivers and passengers can be met.
