Abstract

Abstract A body support applicable to a hospital bed, seat or the like includes a substantially horizontal frame on which a series of carriers are mounted for oscillation about parallel axes transverse of the frame, substantially rectangular-section support blocks of resiliently yieldable material being mounted on the carriers, drive means being provided for oscillating the carriers and the support blocks mounted thereon in unison to tilt the upper faces of the support blocks alternately in both directions from horizontal, varying the pressure applied by all parts of a body supported by the support blocks.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 153 words
A body support of the type having a plurality of resiliently yieldable support members mounted transversely of a substantially horizontal frame, and drive means for moving the support members in unison to vary the pressure on parts of a body supported thereby, wherein; the support members are blocks of substantially rectangular cross-section, the support members are mounted on a series of carriers mounted on the frame for oscillation about a transverse axis, said carriers being of shallow box-like form adapted to receive removably the bottom parts of said support members, said carriers being further provided with elevated ends pivoted near to their tops to said frame for oscillation about axes through the upper parts of said support members, and wherein the drive means is adapted to oscillate the carriers and the support members mounted thereon in unison to tilt the upper surfaces of the support members alternately in opposite directions from substantially horizontal.
Claim 2
Dependent Claim 153 words
A body support of the type having a plurality of resiliently yieldable support members mounted transversely of a substantially horizontal frame, and drive means for moving the support members in unison to vary the pressure on parts of a body supported thereby, wherein; the support members are blocks of substantially rectangular cross-section, the support members are mounted on a series of carriers mounted on the frame for oscillation about a transverse axis, said carriers being of shallow box-like form adapted to receive removably the bottom parts of said support members, said carriers being further provided with elevated ends pivoted near to their tops to said frame for oscillation about axes through the upper parts of said support members, and wherein the drive means is adapted to oscillate the carriers and the support members mounted thereon in unison to tilt the upper surfaces of the support members alternately in opposite directions from substantially horizontal.
Claim 3
Dependent Claim 32 words
A body support according to claim 1 wherein at least one of said support members comprises a number of similar sections mounted end to end on a carrier and individually removable therefrom.
Claim 4
Dependent Claim 36 words
A body support according to claim 1 wherein said drive means includes a link pivotally connected to said carriers, and a motor on said frame driving an eccentric connected by a connecting rod to said link.
