Electrical headrest, particularly for vehicle seats.

(-- A summary 57) The (correction -- owner) purpose The essential structure parts for adjusting height and an inclination to a headrest electrically are incorporated, and equipment in the backrest of a vehicle sheet is made into the minimum. Composition The first motor 17 and ポテンシオ meter 18 are constituted so that it may be attached to the supporting base 19, it may be attached to the housing 2 and the guide rod 15 top can be slid with the spring 20. The guide rod 15 is combined with the support yoke 21, the nut 22 is fixed in the center, and the operation screw 23 is supported. Rotation of the screw within the fixed nut 22 makes it go up and down the supporting base 19, and is headless -- you make it go up and down 1The 2nd motor 30 has geared with the fixed pinion 33 attached to the fixed pivot 16 which it is being rotatably fixed to the supporting base 19 and the housing 2, and the planet pinion 32 is fixed to an output shaft, and corresponds. Thereby, the motor 30 and the housing 31 枢動 in the same direction around the axis line of the pivot 16, and a headrest can give an inclination state.
