Abstract

The preset invention provides headrest reclining module that is mounted on a headrest. The headrest reclining module includes: a base supported on the headrest; a movable bracket coupled to the base to movable forward with respect to the base; a head support panel having an end coupled to the movable bracket to be tiltable forward; and a link which has both ends respectively coupled to the base and the head support panel such that at least one of the ends slides along a predetermined path set in the base or the head support panel and guides the head support panel to be tilted along the predetermined path when the movable bracket is moved.

Claims

1. A headrest reclining module comprising:

a base;

a movable bracket coupled to the base and configured to move forward and backward with respect to the base;

a head support panel having an end coupled to the movable bracket, the head support panel configured to tilt forward; and

a link including a first end and a second end, the first and second ends respectively coupled to the base and the head support panel such that the first end is configured to slide along a predetermined path set in the base or the head support panel when the movable bracket is moved, wherein the first end is configured to guide the head support panel to be tilted.

2. The headrest reclining module of claim 1, further comprising:

a lead screw disposed on the base, protruding forward from the base, and thread-fastened to the movable bracket; and

an actuator configured to rotate the lead screw and to move the movable bracket forward and backward with respect to the base.

3. The headrest reclining module of claim 1, wherein the head support panel has a lower end hinged to the movable bracket such that an upper end of the head support panel is configured to rotate and tilt around the lower end.

4. The headrest reclining module of claim 3, wherein a panel protrusion that protrudes backward is formed at the upper end of the head support panel, and a slide slot that defines the predetermined path to which the first end of the link is connected to be slid is formed in the panel protrusion.

5. The headrest reclining module of claim 4, wherein the second end of the link is rotatably hinged to the lower end of the base.

6. The headrest reclining module of claim 1, wherein a coupling protrusion is formed between the first and second ends of the link to be coupled to the movable bracket, and a guide slot is longitudinally formed in the movable bracket and configured to guide the coupling protrusion sliding therein.

7. The headrest reclining module of claim 4, wherein the slide slot is formed along a lower-rear orthogonal line from the head support panel.

8. The headrest reclining module of claim 1, wherein a coupling protrusion is formed between the first and second ends of the link, a slide slot defining the predetermined path is formed in the head support, and a position of the coupling protrusion on the link is determined at a point where a sum of a first variable distance and a second variable distance is equal to or greater than a horizontal distance from the coupling protrusion to a rear side of the head support panel, and

wherein the first variable distance is a horizontal distance from a rear side of the head support panel to a joint point between the first end of the link and the slide slot, and the second variable distance is a horizontal distance from the coupling protrusion to the joint point between the first end of the link and the slide slot.
