Seat cushion with selectively inflatable interior seat and back compartments
First Claim
Patent Images
1. A seat cushion adapted to selectively conform to a user'"'"'s anatomy comprising:
- (a) a seat portion to underlie a user'"'"'s buttocks when sitting on the seat cushion, the seat portion having at least one inflatable interior seat compartment, a resiliently compressible foam element disposed within the seat compartment and an openable and closable seat valve for selectively communicating the seat compartment with the ambient atmosphere, the foam element being expanded and compressed within the seat compartment in relation to selective application of a compression force acting on the seat portion when the seat valve is opened to selectively draw inflating air into, and exhaust inflating air from, the seat compartment;
(b) a back portion to rest against a user'"'"'s back when sitting on the seat cushion, the back portion having at least one inflatable interior back compartment, a resiliently compressible foam element disposed within the back compartment, and an openable and closable back valve for selectively communicating the back compartment with the ambient atmosphere, the foam element being expanded and compressed within the back compartment in relation to selective application of a compression force acting on the back portion when the back valve is opened to selectively draw air into, and exhaust inflating air from, the back compartment;
(c) means conjoining the seat portion and the back portion to one another for relative pivotal movement along a pivot axis; and
(d) the seat portion and the back portion defining respective concavities at opposite sides of the pivot axis, the concavities collectively forming a pelvic opening between the seat portion and the back portion to receive a user'"'"'s pelvic area when sitting on the seat cushion.

Abstract
An seat cushion is adapted to selectively conform to a user'"'"'s anatomy with a seat portion having at least one inflatable interior seat compartment with a resiliently compressible foam element disposed therein. The compartment also has an openable and closable seat valve for selectively communicating the seat compartment with the ambient atmosphere. The foam is expanded and compressed within the seat compartment in relation to selective application of a compression force acting on the seat portion when the seat valve is opened to selectively draw inflating air into and exhaust inflating air from the seat compartment.

9. A seat cushion adapted to selectively conform to a user'"'"'s anatomy, comprising:
-
(a) a seat portion to underlie a user'"'"'s buttocks when sitting on the seat cushion, the seat portion having an inflatable interior seat compartment, a resiliently compressible foam element disposed within the seat compartment and an openable and closable seat valve for selectively communicating the seat compartment with the ambient atmosphere, (b) the foam being expanded and compressed within the seat compartment in relation to selective application of a compression force acting on the seat portion when the seat valve is opened to selectively draw inflating air into, and exhaust inflating air from, the seat compartment; (c) a back portion to rest against a user'"'"'s lower back when sitting on the seat cushion, the back portion having an inflatable interior back compartment, a resiliently compressible foam element disposed within the back compartment, and an openable and closable back valve for selectively communicating the back compartment with the ambient atmosphere, (d) the foam element in the back compartment being expanded and compressed therewithin in relation to selective application of a compression force acting on the back portion when the back valve is opened to selectively draw inflating air into, and exhaust inflating air from, the back compartment; (e) means conjoining the seat portion and the back portion to one another for relative pivotal movement along a pivot axis; (f) the seat portion and the back portion defining respective concavities at opposite sides of the pivot axis, the concavities collectively forming a pelvic opening between the seat portion and the back portion to receive a user'"'"'s pelvic area when sitting on the seat cushion. - View Dependent Claims (10, 11, 12)

13. A seat cushion adapted to selectively conform to a user'"'"'s anatomy, comprising:
-
(a) a seat portion to underlie a user'"'"'s buttocks when sitting on the seat cushion, the seat portion having two inflatable interior seat compartments, a resiliently compressible foam element disposed within each seat compartment and an openable and closable seat valve for selectively communicating at least one of the seat compartments with the ambient atmosphere, the seat compartments being in communication with each other for selectively communicating both seat compartments with the ambient atmosphere through the seat valve, and the foam elements being expanded and compressed within the seat compartments in relation to selective application of a compression force acting on the seat portion when the seat valve is opened to selectively draw inflating air into, and exhaust inflating air from, the seat compartments; and (b) a back portion to rest against a user'"'"'s back when sitting on the seat cushion, the back portion having two inflatable interior back compartments, a resiliently compressible foam element disposed within each back compartment, and an openable and closable back valve for selectively communicating at least one of the back compartments with the ambient atmosphere, the back compartments being in communication with each other for selectively communicating both back compartments with the ambient atmosphere through the back valve, and the foam elements being expanded and compressed within the back compartments in relation to selective application of a compression force acting on the back portion when the back valve is opened to selectively draw air into, and exhaust inflating air from, the back compartments. - View Dependent Claims (14)
