Abstract
A support for aligning the head and torso. The support includes at least one first bladder containing a fluid. The first bladder is communicatively coupled to at least one second-bladder containing a fluid. When the user is in the side position atop the second bladder, at least a portion of the fluid in the second bladder is displaced into the first bladder by the user's torso. The fluid displaced into the first bladder causes the first bladder to raise the user's head when in the side position atop the first bladder.
Description
BACKGROUND OF THE INVENTION
The present invention relates to improving comfort during sleep. More particularly, the present invention relates to an apparatus and a method for automatically maintaining the proper head and torso alignment when a user is sleeping in either the supine or side position and when the user rolls from the supine to the side position and vice versa.
Proper head and torso alignment while sleeping reduces muscle stress and spinal problems due to improper spinal alignment and improves circulation and respiration.
SUMMARY OF THE INVENTION
The above-mentioned problems associated with improper spinal alignment during sleep and other problems are addressed by the present invention. Embodiments of the present invention provide a support for aligning the head and torso. In one embodiment of the present invention, the support includes at least one first bladder containing a fluid. The first bladder is communicatively coupled to at least one second-bladder containing a fluid. When the user is, in the side position atop the second bladder, at least a portion of the fluid in the second bladder is displaced into the first bladder by the user's torso. The fluid displaced into the first bladder causes the first bladder to raise the user's head when in the side position atop the first bladder.
In another embodiment, the support includes at least one bladder containing a fluid. The bladder has first and second compartments that are communicatively coupled. When the user is in the side position atop the bladder, at least a portion of the fluid in the second compartment is displaced into the first compartment by the user's torso. The fluid displaced into the first compartment causes it to raise the user's head when in the side position atop the bladder.
