Abstract
Official abstract text for this publication.
The present invention relates to a headrest moving device. The headrest moving device includes an ejector casing mounted to a seat frame, a tiltable member tiltably installed in the ejector casing, a stay rod connected to a headrest and passing through the tiltable member, a movable unit having a connector and a mounting holder rotatably coupled to the connector and connected to the stay rod, a screw engaged with the connector in a screw manner of engagement, and a motor for rotating the screw, wherein the tiltable member can be tilted relative to the ejector casing and the mounting holder can be rotated relative to the connector, so that the headrest moving device can easily move the headrest forwards and upwards.
First claim
Opening claim text (preview).
The invention claimed is: 1. A headrest moving device, comprising: an ejector casing mounted to a seat frame; a tiltable member rotatably installed in the ejector casing; a stay rod connected to a headrest and passing through the tiltable member; a movable unit having a connector and a mounting holder rotatably coupled to the connector and connected to the stay rod; a screw engaged with the connector in a screw manner of engagement; a motor for rotating the screw, wherein the tiltable member can be tilted relative to the ejector casing and the mounting holder can be rotated relative to the connector, a spring connected to the connector at a first end thereof and connected to the mounting holder at a second end thereof; and a stopper for limiting an angle that the mounting holder rotates relative to the connector. 2. The headrest moving device as set forth in claim 1 , wherein the mounting holder is provided with an insert hole, into which the stay rod is inserted, and the tiltable member is provided with an ejecting hole, through which the stay rod passes, wherein, at at least one height, a central axis passing through both a center of the ejecting hole and a center of the insert hole is inclined relative to the screw, so that, when the connector is moved upwards, both the mounting holder and the tiltable member are rotated counterclockwise relative to the connector.
