Claim:
A bedsore reduction system for beds comprising: a generally rectangular base plate having front and rear edges and first and second side edges; a generally rectangular mattress support plate operative to support a mattress thereon and having front and rear edges and first and second side edges; a diagonal connecting plate extending between said base plate and said mattress support plate and pivotably connecting said first side edge of said base plate and said second side edge of said mattress support plate; an inflatable upper wedge-shaped air chamber having a generally triangular cross-sectional shape, said upper wedge-shaped air chamber positioned between said mattress support plate and said diagonal connecting plate; an inflatable lower wedge-shaped air chamber having a generally triangular cross-sectional shape, said lower wedge-shaped air chamber positioned between said base plate and said diagonal connecting plate; and controllable inflation means operatively connected to said upper and lower wedge-shaped air chambers for inflating and deflating said upper and lower wedge-shaped air chambers such that said diagonal connecting plate is pivotable relative to said base plate via inflation and deflation of said lower wedge-shaped air chamber and said mattress support plate is pivotable relative to said diagonal connecting plate via inflation and deflation of said upper wedge-shaped air chamber thereby adjusting the yaw orientation relative to horizontal of a mattress supported on said mattress support plate.
