- Considering on initial state of operation represented by Figs. 1A, 2A and 3A, it is seen that
cams 42 located such that the bottom of eachupper portion 22 lies on a location "1" on the edge surface of acam 42. Rotation oflever arm 46 via the ratchet assembly shown in Figs. 3A - 3C causes thecams 42 to rotate about an axis defined byaxle 44, thus causing the bottom of eachupper portion 22 to lie at a location "2" on the edge surface ofcam 42. Since location "2" is distanced further from the axis defined byaxle 44 than is located "1", the rotation of thecams 42 causes theupper portion 22 to be raised relative to thebottom portion 18. - Raising of the
upper portion 22 imparts a raising force to the ribcage engaging belt 24 via resilient straps 26. It is appreciated thatresilient straps 26 are employed to prevent possibly harmful over-tensioning of the user's rib cage and to absorb sudden forces which might otherwise by applied directly to the user's rib cage. -
Upper portion 22 may be lowered relative to thebottom portion 18 by further rotation ofcams 42 usinglever arm 46. - Reference is now made to Figs. 4A, 4B, 5A and 5B, which illustrate a chair mounted device for relieving lower back pressure constructed and operative in accordance with another preferred embodiment of the present invention in respective first and second operative orientations.
- The apparatus of Figs. 4A - 5B is essentially similar to that of Figs. 1A - 3C except in that

- Considering an initial state of operation represented by Figs. 4A and 5A, it is seen that
cams 42 are located such that the bottom of eachintermediate portion 62 lies on a location "1" on the edge surface of acam 42. Rotation oflever arm 46 via the ratchet assembly shown in Figs. 3A - 3C causes thecams 42 to rotate about on axis defined byaxle 44, thus causing the bottom of eachintermediate portion 62 to lie at a location "2" on the edge surface ofcam 42. Since location "2" is distanced further from the axis defined byaxle 44 than is location "1", the rotation of thecams 42 causes theintermediate portion 62 to be raised relative to thebottom portion 18. - Raising of the
intermediate portion 62 causes springs 66 to be tensioned, which applies a raising force to theupper portion 64, causing raising ofupper portion 64. Assuming that straps 72 are taut, the tension on thesprings 66 applies a raising force on the rib cage of a user engaged bystrap assembly 74. It is appreciated that springs 66 are employed to prevent possibly harmful over-tensioning of the user's rib cage and to absorb sudden forces which might otherwise be applied directly to the user's rib cage. - Reference is now made to Fig. 6, which illustrates an alternative embodiment of the invention which is incorporated into a seat, such as a
