Abstract
A pillow of composite construction comprises a first mass of resilient material for conforming to the head and neck region of a human body resting thereon and providing a comfortable support thereto, and an underlying mass of resilient material having a greater density than the first block. The underlying mass is shaped to provide a reactionary force that provides a manipulative action on said head and neck region of the user.
Claims5
A pillow of composite construction for supporting the head and neck region of a human body and providing active traction thereto, the pillow having a front and a rear;
- the pillow comprising:
- an underlying block of material of a first resilience, said underlying block generally having a wedge shape including an inclined surface extending downward in the front to rear direction at an angle;
- an overlying block of material of a second resilience disposed overlying said underlying block, the overlying block providing a comfortable support for a head and neck resting thereon and having a front rounded portion providing a neck supporting surface and a rear ramp surface sloping downwardly to the rear at an angle and generally parallel to the inclined surface of said underlying block below said ramp surface;
- the underlying and overlying blocks of the respective first and second resilience cooperatively defining a resilience differential whereby the resilience differential and the configuration of the two blocks responds to a downward compression caused by the weight of a head and neck resting on the pillow by creating a reactionary force at least in a horizontal direction away from the front of the pillow, said reactionary force thereby providing traction to the head and neck region the underlying block has a protruding ridge at a top of its inclined surface defined by a generally vertical wall extending upwardly from said inclined surface.
