Abstract

An adjustable headrest wherein the headrest independently moves along the substantially vertical axes of the mounting rods in response to a first-applied substantially vertical force applied to the headrest when the button is simultaneously actuated, and further wherein the headrest independently moves along the substantially horizontal axis of the slide rail in response to a second-applied substantially horizontal force applied to the headrest when the button is simultaneously actuated.

Claims

1. An adjustable headrest having mounting rod portions along substantially parallel axes, comprising:

a locking frame having a longitudinal axis and two sides substantially parallel to the longitudinal axis, the locking frame further having a bridge member extending between the two sides, which is substantially perpendicular to the longitudinal axis, the bridge member having a plurality of apertures substantially transverse to the longitudinal axis;

a box frame having first and second slide rails, wherein the first slide rail is in sliding communication with the locking frame and substantially guides the locking frame in the fore/aft direction during use of the headrest;

an enclosure about the mounting rod portions, the enclosure having first and second apertures in sliding communication with the first and second slide rails, respectively, the enclosure further having a locking pin affixed thereto, wherein the locking pin is substantially parallel to the longitudinal axis, wherein the locking pin is adaptable for engagement with any of the plurality of apertures;

a button (connected to/in mechanical communication with) the locking frame, wherein a substantially normal force FN applied to the button sufficient to overcome the return force of a resilient element causes the locking frame to translate/displace along the longitudinal axis of the locking frame and the locking pin to disengage its respective aperture;

a shell connected to the box frame, wherein the shell support a foam element;

wherein the headrest (independently) moves along the substantially vertical axes (of the mounting rods) in response to a first-applied substantially vertical force F1 applied to the headrest when the button is simultaneously actuated; and

further wherein the headrest (independently) moves along the substantially horizontal axis of the slide rail in response to a second-applied substantially horizontal force F2 applied to the headrest when the button is simultaneously actuated.

2. The adjustable headrest of claim 1, wherein the box frame having a plurality of first slide rails.

3. The adjustable headrest of claim 1, wherein the box frame having a plurality of second slide rails.
