Pillow with air bladder insert
View Patent ↗The pillow includes a pillow tick which includes first and second substantially identical fabric members. A chamber extends along the length of the pillow at one longitudinal edge thereof. An air bladder member with crushable foam or polyester pellets is positioned within the chamber. A valve extends from the air bladder member to provide adjustable neck support. Pressure is exerted on the foam with the valve open. When the desired firmness is achieved, the valve is closed. Two baffle members are positioned in the tick volume between the other longitudinal edge of the tick and the chamber. The tick volume contains natural or synthetic fill. The baffles angle toward each other to provide good support and comfort and to reduce movement of the fill.
1. A pillow, comprising:
a pillow tick which includes first and second substantially identical fabric members;
a chamber extending substantially along the length of the pillow at one longitudinal edge of the pillow tick;
a natural or synthetic fill within the tick between the chamber and the other longitudinal edge; and
a bladder member, containing crushable foam, positioned within the chamber, the bladder member including a valve assembly in fluid communication with the chamber which permits a variation in firmness when the valve is open by application of pressure to the crushable foam and then maintains a selected firmness when the valve is closed.
2. The pillow claim 1 , including at least two baffle members positioned between and secured to the first and second sheet members, extending inwardly of the pillow tick from one longitudinal edge thereof toward the other longitudinal edge.
3. The pillow of claim 1 , including two outer fabric members enclosing the first and second fabric members and filling between the outer fabric members and the first and second fabric members.
4. The pillow of claim 1 , wherein the baffle members extend to a point more than halfway toward the other longitudinal edge, but do not contact the chamber.
5. The pillow of claim 2 , wherein the two baffle members angle toward each other or approximately parallel to each other as they extend from the one longitudinal edge.
6. The pillow of claim 4 , wherein free ends of the baffle members are positioned to divide the length of the pillow into three equal sections.
7. The pillow of claim 1 , wherein the chamber is quilted.
8. The system of claim 1 , wherein the chamber is openable by a closure member.
9. The pillow of claim 6 , wherein the closure member is a zipper.
10. The pillow of claim 1 , wherein the bladder member is rectangular.
11. The pillow of claim 1 , wherein the bladder is in the form of a bolster, approximately cylindrical in configuration.
12. The pillow of claim 10 , wherein the crushable foam or polyester in the bladder is in the form of pellets.
13. The pillow of claim 1 , wherein the valve assembly includes a tubular line extending from the interior of the bladder and in fluid communication therewith at a free end of the tubular line.
14. The pillow of claim 10 , including a polyurethane foam layer covering at least a portion of the bladder member.
15. The pillow of claim 13 , wherein the polyurethane foam layer covers all of the bladder member.
16. A pillow, comprising:
a bladder member which includes a cover member having slightly arcuate interior surfaces which extend from one edge to an opposing edge thereof and crushable foam or polyester member or members in the interior thereof;
a valve assembly in fluid communication with the interior of the bladder member, which permits a variation in firmness of the pillow when the valve is open by application of or release of pressure on the crushable foam or polyester and which maintains a selected firmness when the valve is closed; and
a polyurethane foam layer adjacent to and covering at least a portion of the bladder member.
17. The pillow of claim 16 , including two outer fabric members enclosing the bladder member and filling between the outer fabric layers and the bladder member.
18. The pillow of claim 17 wherein the polyurethane foam layer covers all of the bladder member.
19. The pillow of claim 16 , wherein the bladder member is rectangular.
20. The pillow of claim 16 , wherein the crushable foam or polyester is in the form of pellets.
21. The pillow of claim 16 , wherein the valve assembly includes a tubular line extending from the interior of the bladder member and a valve element at a free end of the tubular line.
22. The pillow of claim 16 , wherein the polyurethane foam layer is approximately 0.75 inches thick.
