Definitions
- the present invention provides a pillow containing particulate material such as beads or balls (a “bean pillow”), which is particularly suitable for use during travel.
- a pillow containing particulate material such as beads or balls
- Pillows are known that are particularly suitable for use during travel. Such pillows often are substantially U-shaped in plan view so that the pillow can be wrapped around the back and sides of the neck of the user to support the user's head. Some such pillows are inflatable. Another such pillow, which is sold by the applicant for this patent application, is substantially U-shaped in plan view and contains beads or balls (i.e. is a “bean pillow”). This bean pillow has the advantage that it does not require inflation before use.
- the aim of the present invention is to provide an improved pillow with respect to the known pillows referred to above.
- a first aspect of the present invention provides a pillow, the pillow comprising two wings, and a bridging section connecting the wings, wherein the wings and bridging section together form a substantially U shaped shape in plan view, and the surface of each wing is formed of a surface material, and at least the wings contain particulate material to provide support for the surface material, wherein the thickness of the thinnest portion of the bridging section is less than the thickness of the thickest portion of the wings, and wherein the bridging section comprises a cushion containing a material different from the particulate material.
- a second aspect of the present invention provides a pillow, the pillow comprising two wings, and a bridging section connecting the wings, wherein the wings and bridging section together form a substantially U shaped shape in plan view, and the surface of each wing is formed of a surface material, and at least the wings contain particulate material to provide support for the surface material, wherein the thickness of the thinnest portion of the bridging section is less than the thickness of the thickest portion of the wings, wherein the bridging section comprises a cushion, and wherein the cushion does not comprise or contain the or a particulate material.
- the thickness of the thinnest portion of the bridging section is less than the thickness of the thickest portion of the wings means that the bridging section can be folded and the wings brought together more easily in comparison with known pillows in which the thickness of the bridging section is equal to or greater than the thickness of the wings.
- the folded pillow is also less bulky than known pillows when folded, and thus takes up a smaller space in the user's luggage.
- the pillow of the present invention is intended to be worn around the neck of the user, with the bridging section behind the neck and a wing on each side of the neck, so that the front portion of the neck is open.
- the bridging section provides support for the back of the user's head and the wings provide support for the side of the head.
- the thickness of the thinnest portion of the bridging section is less than the thickness of the thickest portion of the wings does not detract from the comfort of the user when using the pillow, and in fact increases the user's comfort because the smaller thickness of the bridging section does not force the user's head so far away from the surface on which the pillow is resting. Hence the user's neck can be held in a straighter position when the pillow is being used.
- the term “thickness” refers to the height dimension when the pillow is viewed in plan view and the wings and bridging section form a substantially U shaped shape. This dimension is in the direction perpendicular to the surface on which the pillow is resting in normal use. The thinnest part, correspondingly, is the thinnest in the same height dimension.
- the provision of two wings separated by a bridging section which is shaped so that the particulate material either does not pass through the bridging section at all or is restricted in passing through the bridging section might present problems in manufacture as the step of filling the wings with particulate material will be either slowed down or must take place in two steps.
- the present inventors have discovered that the filling step is surprisingly efficient or can be carried out in two separate steps relatively easily by suitable manufacturing steps, such as filling the wings near the bridging section.

- the two wings form a pair of wings.
- a pair of wings provides equal support for each side of the user's head.
- the thickness of the thickest portion of the bridging section is less than the thickness of the thickest portion of the wings. This provides that the bridging section is easier to fold at each point between the wings in comparison with known pillows in which the thickness of the bridging section is equal to or greater than the thickness of the wings.
- the thickness of the thickest portion of each wing is from 60 mm to 120 mm, more preferably from 70 mm to 110 mm, even more preferably from 80 mm to 100 mm, and most preferably from 85 mm to 95 mm.
- the thickness of the thinnest portion of the bridging section is from 5 mm to 15 mm, more preferably 7 mm to 13 mm and most preferably from 8 mm to 12 mm.
- the thickness of the thickest portion of the bridging section is from 50 mm to 90 mm, more preferably 60 mm to 80 mm, and most preferably 65 mm to 75 mm.
- the ratio of the thickness of the thinnest portion of the bridging section to the thickness of the thickest portion of each wing is from 1:4 to 1:24, more preferably from 1:4 to 1:14, more preferably from 1:6 to 1:12, more preferably from 1:8 to 1:12, most preferably from 1:8 to 1:10.
- the ratio of the thickness of the thickest portion of the bridging section to the thickness of the thickest portion of each wing is from 1:0.6 to 1:2.5, more preferably from 1:0.9 to 1:2, more preferably from 1:1 to 1:1.5, more preferably from 1:1.1 to 1:1.5, most preferably from 1:1.2 to 1:1.4.

- the thinnest portion of the bridging section is equidistant from each wing.
- the bridging section is easiest to fold at a point equidistant from each wing and so the pillow can be folded into a particularly small arrangement.
- the bridging section may comprise one or more channels containing the particulate material and extending between the wings.
- One such channel may be provided on the outer edge of the bridging section.
- One such channel may be provided on the inner edge of the bridging section.

- Such differences in thickness provide a particularly advantageous balance of allowing the pillow to be folded easily while providing sufficient support for the back of the user's head.
- each wing has a free end located away from a point where each respective wing is connected to the bridging section, and the distance between the wings at the point that each wing is connected to the bridging section is larger than the distance between the wings at a point adjacent to the free end of each wing. This means that the wings wrap more closely around the neck and thereby provide closer support for the sides of the user's head.

- the pillow is described its unloaded state, i.e., when the pillow has not been manipulated, loaded or molded by the user.
- a pillow 10 comprising a pair of wings 12 , and a bridging section 14 connecting the wings 12 .
- the wings 12 and bridging section 14 together form a substantially U shaped shape in plan view.
- the surface of the wings 12 and bridging section 14 is formed of a surface material, and the wings 12 and bridging section 14 contain beads in this embodiment (or other particulate material such as balls or beans or any combination thereof in other embodiments) to provide support for the surface material.
- the thickness (or depth—the dimension in the direction away from the viewer in FIG. 1 ) of the thinnest portion of the bridging section 14 is less than the thickness of the thickest portion of the wings 12 . This is most clearly shown in FIGS.
- the bridging section 14 comprises a cushion 16 containing a foam material.
- the cushion has a constant thickness of approximately 10 mm.
- the cushion 16 provides the thinnest portion of the bridging section 14 , but in other embodiments the thinnest portion may be provided elsewhere.
- the bridging section 14 does not contain the particulate material, and so the surface of the bridging section 14 is not supported by the particulate material.
- the cushion 16 forms a head zone to support the user's head.
- the thickness of the thickest portion of the wings 12 is shown by arrows X.
- the thickness of a portion of the bridging section 14 is shown by arrows Y.
- the wings 12 are divided from the bridging section 14 by stitching 28 .
- the wings 12 and bridging section 14 may be divided differently, for example the wings 12 may extend further into the bridging section 14 .
- the thickest portion of the wings 12 (which has the same thickness in each wing 12 ) is approximately halfway between the free end 22 of each wing 12 and the outer edge of the bridging section 14 , but the invention is not limited to this.

- An additional, inner layer of material for example Lycra®, may be provided in the bridging section 14 and/or each of the wings 12 .
- the or each additional layer may be stitched to the or each respective outer layer of the bridging section 14 and/or the wings 12 .
- a tube is inserted into a small hole left in the seam and beads are pumped along the tube at high pressure to fill the pillow 10 .
- the filling with beads typically takes under 3 second to complete because there are no internal walls inside the pillow 10 to slow down the filling. Internal walls would present a serious impediment to filling of a pillow with beads. Such internal walls would also significantly reduce the effectiveness of the product as a pillow because the beads must be allowed to move freely throughout the pillow in order to achieve a moulded comfortable fit specifically for the user. This is different from known inflatable pillows, which are suitable for use during travel but contain such internal walls in order to ensure proper inflation.
- the bridging section 14 does not contain particulate material, care must be taken as the two wings must be filled with beads separately, either sequentially, or simultaneously for example by two operatives or in two operations.
- the tube may be passed through the inside of the bridging section 14 to fill a far wing 12 before or after the near wing 12 has been filled.
- the restriction may also make passing the tube through the bridging section 14 difficult.
- Such known inflatable pillows typically are fabricated from weldable fabrics that are welded by heat sealing. Such fabrics are welded together while the pillow is flat and deflated on a press.
- the beads are polystyrene.
- a loop 18 , and a button 20 on a flap of material, are provided on the outer edges of respective wings 12 .

- the button 20 can be received in the loop 18 to fasten the wings 12 together and to retain the pillow 10 in the folded position.
- the thickness of the thickest portion of each wing is approximately 90 mm. In addition, in this embodiment the thickness of the thickest portion of the bridging section 14 is approximately 70 mm. The thickest portion of the bridging section 14 is provided at the two points that the bridging section 14 connects to each wing 12 . This is best shown in FIG. 2 .
- the ratio of the thickness of the thinnest portion of the bridging section to the thickness of the thickest portion of each wing is approximately 1:9.
- the ratio of the thickness of the thickest portion of the bridging section to the thickness of the thickest portion of each wing is approximately 1:1.3.

- One channel 24 is provided on the outer edge of the bridging section 14 (the upper edge as shown in FIG. 1 ).
- the other channel 26 is provided on the inner edge of the bridging section 14 (the lower edge as shown in FIG. 1 ).
- the channels 24 , 26 allow beads to pass between the ends of the bridging section 14 , and between the wings 12 , past the cushion 16 .
- the cushion 16 is defined by stitching in the surface material of the bridging section 14 .
- the foam material of the cushion is substantially trapezoidal in plan view and the stitching surrounds the foam material to maintain the foam material in position.

- the foam material takes up space in the bridging section 14 that would otherwise be occupied by the particulate material.
- the bridging section 14 has an axis extending between the wings 12 (in this embodiment substantially parallel with the straight section of the outer edge of the bridging section 14 ), and the longer sides of the substantially trapezoidal shape of the cushion 16 are substantially parallel to the axis of the bridging section 14 . This provides a wide cushion to support the head of the user.
- the user places the bridging section 14 behind the head of the user and the user wraps the wings 12 around the neck of the user.

Description
- 1. Field of the Invention:
- The present invention provides a pillow containing particulate material such as beads or balls (a “bean pillow”), which is particularly suitable for use during travel.
- 2. Description of the Related Art:
- Pillows are known that are particularly suitable for use during travel. Such pillows often are substantially U-shaped in plan view so that the pillow can be wrapped around the back and sides of the neck of the user to support the user's head. Some such pillows are inflatable. Another such pillow, which is sold by the applicant for this patent application, is substantially U-shaped in plan view and contains beads or balls (i.e. is a “bean pillow”). This bean pillow has the advantage that it does not require inflation before use.
- The aim of the present invention is to provide an improved pillow with respect to the known pillows referred to above.
- A first aspect of the present invention provides a pillow, the pillow comprising two wings, and a bridging section connecting the wings, wherein the wings and bridging section together form a substantially U shaped shape in plan view, and the surface of each wing is formed of a surface material, and at least the wings contain particulate material to provide support for the surface material, wherein the thickness of the thinnest portion of the bridging section is less than the thickness of the thickest portion of the wings, and wherein the bridging section comprises a cushion containing a material different from the particulate material.
- A second aspect of the present invention provides a pillow, the pillow comprising two wings, and a bridging section connecting the wings, wherein the wings and bridging section together form a substantially U shaped shape in plan view, and the surface of each wing is formed of a surface material, and at least the wings contain particulate material to provide support for the surface material, wherein the thickness of the thinnest portion of the bridging section is less than the thickness of the thickest portion of the wings, wherein the bridging section comprises a cushion, and wherein the cushion does not comprise or contain the or a particulate material.
- The fact that the thickness of the thinnest portion of the bridging section is less than the thickness of the thickest portion of the wings means that the bridging section can be folded and the wings brought together more easily in comparison with known pillows in which the thickness of the bridging section is equal to or greater than the thickness of the wings. The folded pillow is also less bulky than known pillows when folded, and thus takes up a smaller space in the user's luggage.
- The pillow of the present invention is intended to be worn around the neck of the user, with the bridging section behind the neck and a wing on each side of the neck, so that the front portion of the neck is open. The bridging section provides support for the back of the user's head and the wings provide support for the side of the head.
- The fact that the thickness of the thinnest portion of the bridging section is less than the thickness of the thickest portion of the wings does not detract from the comfort of the user when using the pillow, and in fact increases the user's comfort because the smaller thickness of the bridging section does not force the user's head so far away from the surface on which the pillow is resting. Hence the user's neck can be held in a straighter position when the pillow is being used.
- In this specification the term “thickness” refers to the height dimension when the pillow is viewed in plan view and the wings and bridging section form a substantially U shaped shape. This dimension is in the direction perpendicular to the surface on which the pillow is resting in normal use. The thinnest part, correspondingly, is the thinnest in the same height dimension.
- The provision of two wings separated by a bridging section which is shaped so that the particulate material either does not pass through the bridging section at all or is restricted in passing through the bridging section might present problems in manufacture as the step of filling the wings with particulate material will be either slowed down or must take place in two steps. The present inventors have discovered that the filling step is surprisingly efficient or can be carried out in two separate steps relatively easily by suitable manufacturing steps, such as filling the wings near the bridging section.
- The surface of the wings is preferably, but not necessarily, formed of the same material as the surface of the bridging section.
- Preferably, the wings are filled with the particulate material. Preferably, the bridging section or part of the bridging section is filled with the particulate material.
- Preferably, the two wings form a pair of wings. A pair of wings provides equal support for each side of the user's head.
- Preferably, the thickness of the thickest portion of the bridging section is less than the thickness of the thickest portion of the wings. This provides that the bridging section is easier to fold at each point between the wings in comparison with known pillows in which the thickness of the bridging section is equal to or greater than the thickness of the wings.
- Preferably, the thickness of the thickest portion of each wing is from 60 mm to 120 mm, more preferably from 70 mm to 110 mm, even more preferably from 80 mm to 100 mm, and most preferably from 85 mm to 95 mm.
- Preferably, the thickness of the thinnest portion of the bridging section is from 5 mm to 15 mm, more preferably 7 mm to 13 mm and most preferably from 8 mm to 12 mm.
- Preferably, the thickness of the thickest portion of the bridging section is from 50 mm to 90 mm, more preferably 60 mm to 80 mm, and most preferably 65 mm to 75 mm.
- Preferably, the ratio of the thickness of the thinnest portion of the bridging section to the thickness of the thickest portion of each wing is from 1:4 to 1:24, more preferably from 1:4 to 1:14, more preferably from 1:6 to 1:12, more preferably from 1:8 to 1:12, most preferably from 1:8 to 1:10.
- Preferably, the ratio of the thickness of the thickest portion of the bridging section to the thickness of the thickest portion of each wing is from 1:0.6 to 1:2.5, more preferably from 1:0.9 to 1:2, more preferably from 1:1 to 1:1.5, more preferably from 1:1.1 to 1:1.5, most preferably from 1:1.2 to 1:1.4.
- Preferably, the ratio of the thickness of the thinnest portion of the bridging section to the thickness of the thickest portion of the bridging section is from 1:3 to 1:18, more preferably from 1:4 to 1:12, more preferably from 1:4 to 1:9, more preferably from 1:5 to 1:9, more preferably from 1:5 to 1:8, most preferably from 1:6 to 1:8.
- Preferably, the thinnest portion of the bridging section is equidistant from each wing. As a result, the bridging section is easiest to fold at a point equidistant from each wing and so the pillow can be folded into a particularly small arrangement.

- Referring to
FIG. 1 , apillow 10 is provided comprising a pair ofwings 12, and abridging section 14 connecting thewings 12. As shown inFIG. 1 , thewings 12 andbridging section 14 together form a substantially U shaped shape in plan view. The surface of thewings 12 andbridging section 14 is formed of a surface material, and thewings 12 andbridging section 14 contain beads in this embodiment (or other particulate material such as balls or beans or any combination thereof in other embodiments) to provide support for the surface material. The thickness (or depth—the dimension in the direction away from the viewer inFIG. 1 ) of the thinnest portion of thebridging section 14 is less than the thickness of the thickest portion of thewings 12. This is most clearly shown inFIGS. 2 and 3 . In the present embodiment, thebridging section 14 comprises acushion 16 containing a foam material. In the present embodiment, the cushion has a constant thickness of approximately 10 mm. In the present embodiment, thecushion 16 provides the thinnest portion of thebridging section 14, but in other embodiments the thinnest portion may be provided elsewhere. - In other embodiments, the
bridging section 14 does not contain the particulate material, and so the surface of thebridging section 14 is not supported by the particulate material. - The
cushion 16 forms a head zone to support the user's head. Referring toFIGS. 2 and 3 , the thickness of the thickest portion of thewings 12 is shown by arrows X. The thickness of a portion of thebridging section 14 is shown by arrows Y. However, it is not possible to see the thickness of thecushion 16 inFIGS. 2 and 3 and so it is not possible to see the thickness of the thinnest portion of thebridging section 14 inFIGS. 2 and 3 . - In
FIG. 1 thewings 12 are divided from thebridging section 14 by stitching 28. However, thewings 12 andbridging section 14 may be divided differently, for example thewings 12 may extend further into thebridging section 14. - In this embodiment, the thickest portion of the wings 12 (which has the same thickness in each wing 12) is approximately halfway between the
free end 22 of eachwing 12 and the outer edge of thebridging section 14, but the invention is not limited to this. - In addition, in the present embodiment the thinnest portion of the
bridging section 14 is equidistant from eachwing 12. This is because the center line CL of thepillow 10 shown inFIG. 1 , which is equidistant from eachwing 12, passes through thecushion 16. Thepillow 10 is axisymmetric about the center line CL. - Referring to
FIG. 2 , the surface of thebridging section 14 is formed from two separate pieces ofmaterial bridging section 14. Similarly, the surface of eachwing 12 is formed from two separate pieces ofmaterial wing 12. Lycra® (elastane) is used as the material for the surface of thebridging section 14 and thewings 12 in this embodiment, but the invention is not limited to this, and other fabrics instead may be used. However, Lycra® provides a stretchy material that allows thepillow 10 to be easily moulded for the user, but other stretchy materials may be used. - In addition, in the embodiment where the
bridging section 14 does not contain the particulate material, the surface of thebridging section 14 need not be formed of a fabric such as Lycra®. - An additional, inner layer of material, for example Lycra®, may be provided in the
bridging section 14 and/or each of thewings 12. The or each additional layer may be stitched to the or each respective outer layer of thebridging section 14 and/or thewings 12. - During filling of the
pillow 10, a tube is inserted into a small hole left in the seam and beads are pumped along the tube at high pressure to fill thepillow 10. After filling the hole in the seam is immediately sewn up. The filling with beads typically takes under 3 second to complete because there are no internal walls inside thepillow 10 to slow down the filling. Internal walls would present a serious impediment to filling of a pillow with beads. Such internal walls would also significantly reduce the effectiveness of the product as a pillow because the beads must be allowed to move freely throughout the pillow in order to achieve a moulded comfortable fit specifically for the user. This is different from known inflatable pillows, which are suitable for use during travel but contain such internal walls in order to ensure proper inflation. - In other embodiments where the
bridging section 14 does not contain particulate material, care must be taken as the two wings must be filled with beads separately, either sequentially, or simultaneously for example by two operatives or in two operations. For example, the tube may be passed through the inside of thebridging section 14 to fill afar wing 12 before or after thenear wing 12 has been filled. - Care must also be taken when filling the
bridging section 14 when thebridging section 14 contains particulate material because the restriction for restricting the amount of particulate material in the bridging section may make filling thebridging section 14 difficult. The restriction may also make passing the tube through thebridging section 14 difficult. - Such known inflatable pillows typically are fabricated from weldable fabrics that are welded by heat sealing. Such fabrics are welded together while the pillow is flat and deflated on a press.
- Preferably, the beads are polystyrene.
- A
loop 18, and abutton 20 on a flap of material, are provided on the outer edges ofrespective wings 12. Theloop 18 and abutton 20 are provided approximately halfway between thefree end 22 of eachwing 12 and the outer edge of thebridging section 14. When thepillow 10 is folded about the center line CL thebutton 20 can be received in theloop 18 to fasten thewings 12 together and to retain thepillow 10 in the folded position. - In this embodiment the thickness of the thickest portion of each wing is approximately 90 mm. In addition, in this embodiment the thickness of the thickest portion of the
bridging section 14 is approximately 70 mm. The thickest portion of thebridging section 14 is provided at the two points that thebridging section 14 connects to eachwing 12. This is best shown inFIG. 2 . - In this embodiment, the ratio of the thickness of the thinnest portion of the bridging section to the thickness of the thickest portion of each wing is approximately 1:9.
- In this embodiment, the ratio of the thickness of the thickest portion of the bridging section to the thickness of the thickest portion of each wing is approximately 1:1.3.
- In this embodiment, the ratio of the thickness of the thinnest portion of the bridging section to the thickness of the thickest portion of the bridging section is approximately 1:7.
- In the present embodiment, the
bridging section 14 comprises twochannels wings 12. Onechannel 24 is provided on the outer edge of the bridging section 14 (the upper edge as shown inFIG. 1 ). Theother channel 26 is provided on the inner edge of the bridging section 14 (the lower edge as shown inFIG. 1 ). Thechannels bridging section 14, and between thewings 12, past thecushion 16. - The
cushion 16 is defined by stitching in the surface material of thebridging section 14. The foam material of the cushion is substantially trapezoidal in plan view and the stitching surrounds the foam material to maintain the foam material in position. Other material may be used instead of foam material. - In this embodiment, the stitching defining the
cushion 16 and the foam material of thecushion 16 provides a restriction for restricting the amount of particulate material in thebridging section 14, to restrict the thickness of thebridging section 16. The stitching defining thecushion 16 joins the lower surface of thebridging section 14 to the upper, opposing surface of thebridging section 14. The stitching restricts the size of the space formed by these opposing surfaces of thebridging section 14. In addition, the foam material takes up space in thebridging section 14 that would otherwise be occupied by the particulate material. - The
bridging section 14 has an axis extending between the wings 12 (in this embodiment substantially parallel with the straight section of the outer edge of the bridging section 14), and the longer sides of the substantially trapezoidal shape of thecushion 16 are substantially parallel to the axis of thebridging section 14. This provides a wide cushion to support the head of the user. - In use of the
pillow 10 the user places thebridging section 14 behind the head of the user and the user wraps thewings 12 around the neck of the user. Thepillow 10 is then placed upon a surface and thebridging section 14 provides support for the back of the user's head and thewings 12 provide support for the sides of the user's head. - In this embodiment, the difference in thickness between the thinnest portion of the bridging section 14 (at the center line CL) and the thickest portion of the
wings 12 is approximately 80 mm. - The
free end 22 of eachwing 12 is provided away from a point that eachrespective wing 12 is connected to thebridging section 14. The distance between thewings 12 at the point that eachwing 12 is connected to thebridging section 14 is larger than the distance between thewings 12 at a point adjacent to thefree end 22 of eachwing 12. This is clearly shown inFIG. 1 where thewings 12 are closer at their free ends 22 than at their other ends where they connect to thebridging section 14. - It can be seen from
FIGS. 2 and 3 that the central portion of thebridging section 14, i.e. the portion adjacent to the center line CL is considerably thinner than the thickest portion of thewings 12. -
FIGS. 4 and 5 show the detail of thebridging section 14 and it can be seen fromFIGS. 4 and 5 that the upper surface of thecushion 16 is below the highest point of the rest of thebridging section 14, in particular is below the highest point ofchannels pillow 10 is symmetrical about a horizontal plane and, in this embodiment, about theseam 34 of thebridging section 14 and theseam 40 of eachwing 12. Therefore, the lower (underside) surface (not shown inFIGS. 4 and 5 ) of thecushion 16 is above the lowest point of the rest of thebridging section 14, in particular is above the lowest point ofchannels cushion 16 provides the thinnest portion of thebridging section 14 in this embodiment, but in other embodiments the thinnest portion may be provided elsewhere, for example in thechannel 24 and/or 26. -
FIGS. 6 and 7 show the thickness of the thickest portion of thewings 12 is shown by arrows X.FIGS. 6 and 7 show that, in this embodiment, the thickest portion of the wings 12 (which has the same thickness in each wing 12) is approximately halfway between thefree end 22 of eachwing 12 and the outer edge of thebridging section 14, but the invention is not limited to this. - The
loop 18 and/or thebutton 20 is/are provided respectively on theseam 40 of eachwing 12 i.e. approximately in the middle in the depth direction of eachwing 12. - Referring to
FIGS. 1 , 4 and 5, thebridging section 14 curves (when viewed in plan; towards the bottom inFIG. 1 ) from where it connects to eachwing 12 to a substantially flat section comprising thecushion 16 and thechannels wings 12. - In this embodiment, the width of a portion of the wings 12 (when viewed in plan) is substantially the same as the width of a portion of the
bridging section 14. The width of eachwing 12 is the distance between the outer edge of thewing 12 and the inner edge of thewing 12 with reference to thepillow 10 shown inFIG. 1 . The width of thebridging section 14 is the distance between the outer edge and the inner edge. - In this embodiment, the width of the
wings 12 and bridging section is from 120 mm to 140 mm. The maximum width of thebridging section 14 is approximately 140 mm and the minimum width of thebridging section 14 is approximately 120 mm. In this embodiment, the minimum width of thebridging section 14 is at the center line CL. - In this embodiment, the longer dimension of the substantially
trapezoidal cushion 16, which is substantially parallel with the longer side, is approximately 120 mm. The shorter dimension of the substantiallytrapezoidal cushion 16, which is substantially parallel with the shorter side, is approximately 80 mm. - The preferred embodiment of the present invention has been described purely by way of example, and various modifications, additions and/or omissions will present themselves to one skilled in the art, all of which form part of the invention, together with their equivalents.
