Abstract

The preset disclosure provides a 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 move 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 first and second ends respectively coupled to the base and the head support panel such that the first end of the link slides along a predetermined path set in the base or the head support panel and guides the head support panel to be tilted when the movable bracket is moved.

First claim

The invention claimed is:

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 and including a panel protrusion, the head support panel having a bisecting line at a middle of a height thereof and 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 panel protrusion of the head support panel,
wherein the panel protrusion includes a first portion and a second portion, and the first portion is extended backward from and perpendicular to the head support panel,
wherein the first portion includes a first edge and a second edge, the first portion is directly connected to the head support panel at the first edge in a direction perpendicular to the head support panel, and the second portion is continuously and directly extended from the first portion in a lower and rearward direction toward the bisecting line of the head support panel,
wherein the first end of the link is configured to slide along a predetermined path set in the second portion of the head support panel when the movable bracket is moved,
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, and
wherein a slide slot is formed in the second portion of the panel protrusion along a longitudinal direction of the second portion and configured to define the predetermined path along which the first end of the link slides.

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 panel protrusion is formed at the upper end of the head support panel.

4. The headrest reclining module of claim 3 , wherein the second end of the link is rotatably hinged to the lower end of the base.

5. 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.

6. The headrest reclining module of claim 1 , wherein a coupling protrusion is formed between the first and second ends of the link, 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.
