Abstract
Abstract An elongate cushion for therapeutically supporting a person in an arched face-down prone position. The cushion has an upper surface which slopes upwardly from each end toward the middle. At least one end has a channel the sides of which support a person's head placed face-down therein, with the channel serving as an unobstructed air passageway. The preferred embodiment consists of an assembly of three nestable pillows. Two end pillows, each having a channel, support an intermediate pillow. Also, the end pillows are sized so that, when spaced apart, they will, in cooperation with a horizontal support surface on which they are placed, support a person in a supine position.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
262 words
An assembly of therapeutic resilient pillows operatively placeable on a generally horizontal support surface for supporting a person in an arched face-down prone position, said assembly comprising a pair of end pillows, each pillow having a generally planar bottom surface, and a pair of generally oppositely inclined generally rectangular planar upper surfaces sloping in predetermined directions, facing upwardly away from each other and having a common generally horizontal upper ridge, said end pillows being placeable, in operative position, adjacent each other in such a manner that each end pillow has one of said upper surfaces facing inward toward the other end pillow to form, in combination, a valley, an intermediate pillow nestable in said valley and having, when nested therein, a pair of generally oppositely inclined generally rectangular upper surfaces facing upwardly away from each other and having a common generally horizontal upper ridge, said pillows forming, when assembled in operative position, an elongate cushion having a generally planar horizontal bottom surface and a pair of generally oppositely inclined generally rectangular upper surfaces facing upwardly away from each other and having a common generally horizontal upper ridge, and means defining a channel in at least one of said end pillows, which channel opens through the upper surface facing outwardly away from the other end pillow when said pillows are in operative position, said means including walls defining said channel appropriately spaced apart to support the head of a person whose face is placed in said channel, said channel forming an unobstructed air passageway from such a face to air surrounding said pillow.
Claim 2
Dependent Claim
262 words
An assembly of therapeutic resilient pillows operatively placeable on a generally horizontal support surface for supporting a person in an arched face-down prone position, said assembly comprising a pair of end pillows, each pillow having a generally planar bottom surface, and a pair of generally oppositely inclined generally rectangular planar upper surfaces sloping in predetermined directions, facing upwardly away from each other and having a common generally horizontal upper ridge, said end pillows being placeable, in operative position, adjacent each other in such a manner that each end pillow has one of said upper surfaces facing inward toward the other end pillow to form, in combination, a valley, an intermediate pillow nestable in said valley and having, when nested therein, a pair of generally oppositely inclined generally rectangular upper surfaces facing upwardly away from each other and having a common generally horizontal upper ridge, said pillows forming, when assembled in operative position, an elongate cushion having a generally planar horizontal bottom surface and a pair of generally oppositely inclined generally rectangular upper surfaces facing upwardly away from each other and having a common generally horizontal upper ridge, and means defining a channel in at least one of said end pillows, which channel opens through the upper surface facing outwardly away from the other end pillow when said pillows are in operative position, said means including walls defining said channel appropriately spaced apart to support the head of a person whose face is placed in said channel, said channel forming an unobstructed air passageway from such a face to air surrounding said pillow.
Claim 3
Dependent Claim
26 words
The assembly of claim 1 wherein said head-supporting channel walls extend generally normal to the ridge of each end pillow having said means defining a channel.
Claim 4
Dependent Claim
174 words
An assembly of therapeutic resilient pillows operatively placeable on a generally horizontal support surface for supporting a person in an arched face-down prone position, said assembly comprising a pair of end pillows, each pillow having a generally planar bottom surface, and a pair of generally oppositely inclined upper surfaces facing upwardly away from each other and joining at a common upper ridge, said end pillows being placeable, in operative position, adjacent each other in such a manner that each end pillow has one of said upper surfaces facing inward toward the other end pillow to form, in combination, a valley, and an intermediate pillow nestable in said valley and having, when nested therein, a pair of generally oppositely inclined upper surfaces facing upwardly away from each other and joining at a common upper ridge, said pillows forming, when assembled in operative position, an elongate cushion having a generally planar horizontal bottom surface and a pair of generally oppositely inclined upper surfaces facing upwardly away from each other and joining at a common upper ridge.
Claim 5
Dependent Claim
174 words
An assembly of therapeutic resilient pillows operatively placeable on a generally horizontal support surface for supporting a person in an arched face-down prone position, said assembly comprising a pair of end pillows, each pillow having a generally planar bottom surface, and a pair of generally oppositely inclined upper surfaces facing upwardly away from each other and joining at a common upper ridge, said end pillows being placeable, in operative position, adjacent each other in such a manner that each end pillow has one of said upper surfaces facing inward toward the other end pillow to form, in combination, a valley, and an intermediate pillow nestable in said valley and having, when nested therein, a pair of generally oppositely inclined upper surfaces facing upwardly away from each other and joining at a common upper ridge, said pillows forming, when assembled in operative position, an elongate cushion having a generally planar horizontal bottom surface and a pair of generally oppositely inclined upper surfaces facing upwardly away from each other and joining at a common upper ridge.
Claim 6
Dependent Claim
269 words
An assembly of therapeutic resilient pillows operatively placeable on a generally horizontal support surface for supporting a person alternatively in an arched face-down prone position or in a supine position, said assembly comprising a pair of end pillows, each pillow having a generally planar bottom surface and a pair of generally oppositely inclined upper surfaces facing upwardly away from each other and joining at a common upper ridge, said end pillows being placeable, in operative position, adjacent each other in such a manner that each end pillow has one of said upper surfaces facing inward toward the other end pillow to form, in combination, a valley, and an intermediate pillow nestable in said valley and having, when nested therein, a pair of generally oppositely inclined upper surfaces facing upwardly away from each other and joining at a common upper ridge, said end pillows forming, when assembled in operative position with said intermediate pillow nested in the valley formed by the end pillows, an elongate cushion having a generally planar horizontal bottom surface and a pair of generally oppositely inclined upper surfaces facing upwardly away from each other and joining at a common upper ridge, said end pillows further being capable of forming, when generally assembled without the intermediate pillow in relative orientation corresponding with the orientation of said end pillows in operative position, an assembly capable of supporting a person in a supine position with one of said end pillows supporting the person's legs with the knees superposed the upper ridge of said end pillow and the other end pillow supporting at least a portion of the person's torso.
Claim 7
Dependent Claim
