A headrest (2) for a vehicle seat (3), comprising an adjustment device (1) having: at least two adjustment portions (10A-10D, 11A, 11B); and a drive element (13A-13D) movable along an axis (D), where the drive element (13A-13D) is coupled to the adjustment portion (10A10D, 11A, 11B) via an engaged drive profile (15A-15J), where the drive profile is defined for each of the adjustment portions (10A-10D, 11A, 11B), the drive profile depicts at least one adjustment path (B1-B5), and the drive element (13A-13D) is movable along the axis (D). The adjustment path (B1-B5) of at least one of the adjustment portions (10A-10D, 11A, 11B) has a torsion with respect to the axis (D) and extends from the adjustment path (B1-B5) of at least another of the adjustment portions (10A-10D, 11A, 11B) such that an axial movement of the drive member (13A-13D) along the axis (D) causes a relative rotation between the adjustment portions (10A-10D, 11A, 11B).

    一种用于车辆座椅(3)的头枕(2),包括调节装置(1),所述调节装置具有:至少两个调节部分(10A‑10D、11A、11B);和驱动元件(13A‑13D),所述驱动元件能够沿轴线(D)移动,其中,所述驱动元件(13A‑13D)经由接合的驱动轮廓(15A‑15J)联接到所述调节部分(10A10D、11A、11B),其中所述驱动轮廓被限定用于每个所述调节部分(10A‑10D、11A、11B),所述驱动轮廓描画出至少一个调节路径(B1‑B5),至少一个所述调节部分(10A‑10D、11A、11B)的所述调节路径(B1‑B5)具有相对于所述轴线(D)的扭转并且从至少另一个所述调节部分(10A‑10D、11A、11B)的所述调节路径(B1‑B5)延伸,使得所述驱动构件(13A‑13D)沿所述轴线(D)的轴向移动引起所述调节部分(10A‑10D、11A、11B)之间的相对旋转。
