Maternity air mattress with adjustable bellows system

摘要

An improved multiple chambered maternity mattress ( 10 ) is specially configured to include a bellows ( 24 ) for providing fine-grained adjustability of size and firmness of its centrally disposed womb well region (AWW). The bellows ( 24 ) consisting of a plurality of accordion-like sections which are interconnected to form a single expandable air chamber that is inflatable under the control of the user while actually in use via a remote control unit ( 16 ). The womb well is formed as a cylindrical cavity or opening ( 26 ) which extends for the full height of the mattress ( 10 ) such that the bellows ( 24 ) may change its effective height thereby establishing the physical size of the womb well for optimum user comfort and benefit. Low friction materials and/or coatings on the cylindrical cavity walls ( 28 ) assure minimal friction of the contacting surfaces and bellows tips assuring an infinitely fine height/size/firmness adjustment.
