Abstract

A compliant cover sheet is provided for a face-down pillow which has a wedge shape and contains primary and secondary air passageways which facilitate breathing by the user of the pillow. The sheet is fabricated of a single piece of flat compliant thin material cut so as to have a perimeter edge configuration generally matching the configuration of the pillow. Intersecting slits adjacent the upper extremity of the sheet form triangular flaps which descend into the primary passageway. Fastening straps attached to the flaps are adapted to pass through the secondary air passageways and interengage edges of the sheet. A stabilizing strap attached across opposed edges of the sheet adjacent its lower extremity is adapted to embrace the pillow.

Claims

1. A compliant cover sheet adapted for use upon a wedge-shaped face-down pillow comprised of a resilient wedge elongated between an anterior portion and a posterior extremity and bounded by upper and lower surfaces converging at said posterior extremity, opposed side surfaces of generally triangular shape, and a rectangularly shaped front surface extending between said upper and lower surfaces and terminating said anterior portion, said anterior portion having a substantially centered primary air passageway of rectangular cross-sectional contour, opposed transverse vent passages, each communicating between one of said side surfaces and said primary air passageway, and a longitudinal vent passage communicating between said primary air passageway and said front surface, said cover sheet comprised of a piece of compliant thin material adapted to cover said upper surface in overlying juxtaposition and having:

a) a perimeter defined by forward and rear edges, paired parallel side edges emergent from said rear edge, and paired diagonal edges convergent between said side edges and said forward edge, said forward edge adapted to be disposed upon the front surface of said pillow and said rear edge adapted to associate with the posterior extremity of said pillow,

b) perpendicularly bisecting slits in said sheet, said slits intersecting at a midpoint positioned to be centered above said primary air passageway and defining forward, rear and paired side triangular flaps, each having an apex corresponding to said midpoint, said flaps adapted to hang within said primary air passageway and thereby defining a breathing aperture in said sheet bounded in part by four fold lines, each extending between two contiguous extremities of said slits and coinciding with the rectangular contour of said primary air passageway,

c) paired fastening strap means for said side flaps, each strap means having a first extremity attached to a side flap and a second extremity removably associated with a corresponding tapered edge of said sheet, said strap means adapted to be routed downwardly through said primary air passageway and out through one of the transverse vent passages to association with said tapered edge,

d) forward flap fastening strap means elongated between a first extremity attached to said forward flap and a second extremity removably associated with the forward edge of said sheet, said forward flap fastening strap means adapted to be routed downwardly through said primary air passageway and outwardly through said longitudinal vent passage to association with said forward edge, and

e) lower stabilizing strap means elongated between extremities associated with each of said parallel edges and adapted to encircle said pillow adjacent and parallel to the posterior edge thereof.

2. The cover sheet of claim 1 wherein attachment means are associated with said fastening strap means and corresponding edge of said sheet in a manner to facilitate rapid and secure engagement of said strap means with said sheet.

3. The cover sheet of claim 2 wherein said attachment means is selected from the group consisting of VELCRO hook and loop material, snap fasteners and pressure-sensitive material.

4. The cover sheet of claim 1 wherein said lower stabilizing strap means has elastomeric characteristics.

5. The cover sheet of claim 1 wherein said piece of compliant material is comprised of hydrophilic fibrous material and is permeable to moisture.

6. The cover sheet of claim 5 wherein said edges are treated to prevent unravelling.
