Abstract

본 발명은 자동차용 헤드레스트의 전, 후이동조절장치에 관한 것으로서, 보다 상세하게는 헤드레스트(10)의 저면에 형성된 안내공(12)에는 삽입되는 가이드봉(20)의 상단은 랙기어(22)가 형성되고, 하단은 시트백(4)의 상부에 고정설치되어 있다. 헤드레스트(10)의 내측에 고정설치되는 구동모터(30)의 선단에 설치된 위엄기어(32)는 헤드레스트(10)의 내부에 회전가능하게 설치된 축(60)에 결합된 제2피니언기어(50)와 치합되고, 제2피니언기어(50)와 동축상에 놓여지는 제1피니언기어(40)는 가이드봉(20)의 상단에 형성된 랙기어(22)와 치합되도록 함으로써, 자동차의 실내로 승차하는 승객의 신체부위중 목부위가 안착되는 헤드레스트(10)를 구동모터(30)로써 전, 후 이동시킴에 따라 승객이 편안한 자세에서 목부위를 적절하게 안착시킬 수 있는 효과를 갖는 것이다.More specifically, the upper end of a guide bar (20) inserted into a guide hole (12) formed on a bottom surface of a headrest (10) is connected to a rack gear 22, and the lower end thereof is fixed to the upper portion of the seatback 4. As shown in Fig. The dignified gear 32 provided at the front end of the drive motor 30 fixed to the inside of the headrest 10 is rotatably supported by a second pinion gear (not shown) coupled to a shaft 60 rotatably installed in the headrest 10 And the first pinion gear 40 coaxial with the second pinion gear 50 is engaged with the rack gear 22 formed at the upper end of the guide rod 20, The headrest 10 in which the neck part of the body part of the riding passenger is seated is moved forward and backward by the driving motor 30 so that the passenger can properly seat the neck part in a comfortable posture.

Description

Front and rear movement control of headrests for automobiles

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음Since this is a trivial issue, I did not include the contents of the text.

제2도는 본 발명에 따른 헤드레스트의 전·후이동조절장치를 나타낸 요부사시도이다. 제3도의 (가) (나)는 본 발명에 따른 헤드레스트가 작동모터의 정·역회전에 의해 전방 또는 후방으로 이동된 상태를 나타낸 요부단면도이다.FIG. 2 is a perspective view showing a front and rear movement adjusting device of a headrest according to the present invention; FIG. 3 (B) is a cross-sectional view of the main part showing a state in which the headrest according to the present invention is moved forward or backward by forward and backward rotation of the operating motor.

Claims
