Adjustable headrest

An adjustable headrest for supporting the head of a user thereon, wherein the angles between the user's head with respect to both the user's neck and spine may be selectively adjusted, the headrest comprised of:

• a support for supporting the user's body thereon;
• a headrest having opposite sides for receiving and supporting thereon the user's head at respective selected angles between the user's neck and spine;
• a pair of pivotal coupling elements disposed between the support and opposite sides of the headrest, each coupling element having a respective first end being pivotally connected to and carried by the support, so as to vertically pivot about the first ends relative to the support;
• means including a cam clamp formed between each of the first ends of the coupling elements and the support for selectively double-releasing and double-locking the coupling elements at an desired angle relative to the support with a single camming action, whereby the angle between the user's head and the user's spine may be selectively adjusted and maintained;
• each coupling element further having a respective second opposite end being pivotally connected to the opposite sides of the headrest, such that the headrest is stably carried thereby, so that the headrest vertically pivots about the second ends of the coupling elements;
• means including a cam clamp formed between at least one of the second ends of the coupling elements and the head rest for selectively releasing and locking the headrest at any desired angle relative to the support with a camming action, whereby the angle between the user's head and the user's neck may be selectively adjusted;
• whereby a headrest is provided that is selectively adjustable for positioning the user's head at the desired angle between both the user's spine and neck.

An adjustable headrest for supporting the head of a user thereon, the headrest being comprised of:

• a pair of parallel support rods carried by a support, so as to extend outwardly therefrom;
• a pair of pivotal coupling elements, each of said coupling elements having a respective first end being pivotally connected to and carried by one of the respective support rods, so as to vertically pivot about the support rod on which said element is carried, whereby the angle of the coupling elements with respect to the support rods may be selectively adjusted;
• means formed between the first ends of the coupling elements and the support rods for selectively double-releasing and double-locking the coupling elements at any desired angle relative to the support rods, whereby the angle between the user's head and the user's spine may be selectively adjusted and maintained;
• a first cam clamp, the first cam clamp being associated with the first end of the coupling elements and the support rods for selectively unlocking and double-releasing the coupling elements, so that the angle of the coupling elements relative to the support rods may be selectively adjusted, and for selectively double-locking the coupling elements at the angle selected, so that the selected angle of the coupling elements relative to the support rods may be maintained;
• each coupling element further having a respective second opposite end being pivotally connected to the headrest, such that the headrest is stably carried thereby, so that the headrest vertically pivots about the second ends of the coupling elements;
• the headrest including a headrest frame having opposite sides that are carried by the second ends of the coupling elements for pivotal movement therewith, whereby the adjustment of the angle of the coupling elements relative to the support rods concomitantly selectively adjusts the angle of the headrest frame with respect to the support rods;
• a headrest pad for receiving and supporting thereon the user's head at respective selected angles between the user's neck and spine, the headrest pad being carried by the headrest frame for pivotal movement therewith, whereby the adjustment of the angle of the coupling elements relative to the support rods concomitantly selectively adjusts the angle of the headrest pad with respect to the support rods;
• means formed between at least one of the second ends of the coupling elements and the headrest frame for selectively releasing and locking the headrest frame and the headrest pad carried thereon at any desired angle relative to the support, whereby the angle between the user's head and the user's neck may be selectively adjusted;
• a second cam clamp, the second cam clamp being associated with the second end of one of the respective coupling elements and the headrest frame for selectively unlocking the headrest frame, so that the angle of the headrest frame and the headrest pad carried thereon relative to the second ends of the coupling elements may be selectively adjusted and locking the headrest frame at the angle selected, so that the selected angle of the headrest frame and the headrest pad carried thereby relative to the coupling elements may be maintained;
• such that either cam clamp may be operated with the use of only one hand while the other hand holds and moves the headrest pad for selectively adjusting angle of the headrest pad with respect to the support;
• whereby a headrest is provided that is selectively adjustable for positioning the user's head at the desired angle between both the user's spine and neck.
