Claims

[Scope of Claim for Utility Model Registration] (1) Support frames for the headrest are provided on the left and right sides of the upper part of the seat bag, and between the support frames, there is a hole opening with a through hole in the center and a rotation center axis in the lower part. A head rest is positioned, and the central axis of rotation of the perforated head rest is supported between the left and right support frames so as to be movable up and down, and an electric vertical movement mechanism for the central axis of rotation is provided in at least one of the support frames. A headrest further comprising: an electric rotating mechanism disposed within the perforated headrest for rotating the perforated headrest back and forth about a rotation center axis. (2) In paragraph 1 of the claims for utility model registration,
The electric vertical movement mechanism of the rotation center shaft consists of a synthetic resin female screw block fixed to a fixed bracket, and a drive screw supported on the support frame that is screwed into this female screw block. axis and
The head rest consists of a forward and reverse rotation motor that rotates this drive screw shaft. (3) Scope of claims for utility model registration, paragraph 1 or 2
In paragraph 1, the electric rotation mechanism of the perforated headrest includes a sector gear fixed so as not to rotate coaxially with the rotation center axis, an intermediate gear supported by the perforated headrest and meshed with the sector gear, and a rotary drive of the intermediate gear. A head rest consisting of a forward and reverse rotation motor supported by a perforated head rest. (4) Scope of claims for utility model registration, paragraphs 1 to 3
In any one of the above items, the perforated head rest has left and right side plates, and a pipe shaft into which a rotation center shaft is fitted relatively rotatably is fixed to the lower part of the left and right side plates. (5) Scope of claims for utility model registration, paragraph 3 or 4
In the section, intermediate gears and forward/reverse rotating motors are
A headrest supported by one side plate of a perforated headrest.
