Abstract

Abstract A person can be supported in a reclining position on a support device that includes a back cushion defined by an annular curved frame, and a beaded cushion panel anchored to the frame. The back cushion is connected to a seat cushion and a supporting stand by a cable system having terminal end areas tied together at selected points by a cable clamp mechanism. The cable clamp mechanism can be moved along mating areas of the cable to swing the lower end of the stand toward or away from the lower edge of the back cushion. The inclination angle of the back cushion can be adjusted, or varied, by changing the position of the clamp mechanism on the cable.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 291 words
A device for partially supporting a person in a reclining position comprising: a seat cushion; a back cushion; a stand for supporting said back cushion in an inclined upright position; and a cable means interconnecting said seat cushion, back cushion and stand, whereby said stand serves as a support for the back cushion; said seat cushion having a rear edge and two spaced cable anchorage holes proximate to said rear edge; said back cushion comprising an annular curved frame having a left side edge, a rear side edge, an upper edge, and a lower edge; said frame having a front face, and a rear face; cord anchorage groove means in the rear face of said frame; criss-crossing cords having anchoring loops in said groove means; beads strung on said criss-crossing cords to form a beaded cushion surface; and locking strips in said groove means overlying the anchoring loops; said stand having pivotal connections with the rear face of said frame so that the stand can swing around said pivotal connections to adjust the inclination angle of said back cushion; said frame having two openings proximate to said frame lower edge in registry with the aforementioned cable anchorage holes in said seat cushion; said stand having two cable guide holes aligned with the openings in said frame; said cable means comrising a flexible cable having duplicate cable sections extendable from the cable anchorage holes in said seat cushion through said frame openings and cable guide holes; said duplicate cable sections having matable terminal end areas; and a cable clamp means positionable at selected points along the cable end areas to vary the distance between said frame openings and said cable guide holes, to thereby adjust the inclination angle of the back cushion.
Claim 2
Independent Claim 291 words
A device for partially supporting a person in a reclining position comprising: a seat cushion; a back cushion; a stand for supporting said back cushion in an inclined upright position; and a cable means interconnecting said seat cushion, back cushion and stand, whereby said stand serves as a support for the back cushion; said seat cushion having a rear edge and two spaced cable anchorage holes proximate to said rear edge; said back cushion comprising an annular curved frame having a left side edge, a rear side edge, an upper edge, and a lower edge; said frame having a front face, and a rear face; cord anchorage groove means in the rear face of said frame; criss-crossing cords having anchoring loops in said groove means; beads strung on said criss-crossing cords to form a beaded cushion surface; and locking strips in said groove means overlying the anchoring loops; said stand having pivotal connections with the rear face of said frame so that the stand can swing around said pivotal connections to adjust the inclination angle of said back cushion; said frame having two openings proximate to said frame lower edge in registry with the aforementioned cable anchorage holes in said seat cushion; said stand having two cable guide holes aligned with the openings in said frame; said cable means comrising a flexible cable having duplicate cable sections extendable from the cable anchorage holes in said seat cushion through said frame openings and cable guide holes; said duplicate cable sections having matable terminal end areas; and a cable clamp means positionable at selected points along the cable end areas to vary the distance between said frame openings and said cable guide holes, to thereby adjust the inclination angle of the back cushion.
Claim 3
Dependent Claim 66 words
The device of claim 1, wherein said cord anchorage groove means comprises a channel in the rear face of said frame, and a plurality of notches communicating with said channel so that each anchoring loop extends through two notches and a portion of said channel; said locking strips extending within said channels; each locking strip having a flange overlying the notches associated with the respective channel.
Claim 4
Dependent Claim 65 words
The device of claim 1, wherein said cable clamp means comprises a three piece assembly that includes a central hollow binding element having two passages for the cable sections, a first annular retainer slidable on the cable sections into said hollow binding element in one direction, and a second annular retainer slidable on the cable sections into said hollow binding element in the other direction.
