Abstract

An adjustable ventilation mattress including an inflatable upper filling layer consisted of rows of inflatable plastic tubes arranged in the longitudinal direction, an inflatable lower filling layer consisted of rows of inflatable plastic tubes arranged in the transverse direction below the inflatable upper filling layer, an air permeable covering covered over the inflatable upper and lower filling layers, and a controller controlled to inflate or selectively inflate the inflatable plastic tubes of the inflatable upper filling layer and/or the inflatable lower filling layer according to a predetermined setting for changing the configuration of the mattress.

Claims

1. An adjustable ventilation mattress comprising:

(a) an inflatable upper layer defining a plurality of inflatable upper plastic tubes in horizontal and vertical spaced relation extending in a longitudinal direction, each of said inflatable upper plastic tubes having a respective air intake terminal and a respective air outlet terminal;

(b) a plurality of ventilation tubes extending in said longitudinal direction positionally located between adjacently positioned upper plastic tubes, each of said ventilation tubes having vent holes passing through a sidewall thereof;

(c) an inflatable lower layer defining a plurality of inflatable lower plastic tubes in horizontal and vertical spaced relation extending in a transverse direction, under the entire upper layer each of said inflatable plastic tubes having a respective air intake terminal and a respective air outlet terminal;

(d) an enclosed cover layer for enclosing said inflatable upper layer, said ventilation tubes and said inflatable lower layer; and

,

(e) air control let means for selectively and individually inflating and deflating said upper and lower plastic tubes, said air controller means being fluidly coupled to each of said air intake and outlet terminals of each of said inflatable upper and lower plastic tubes, said air controller means being fluidly coupled to each of said ventilation tubes for passage of air therethrough.
