Abstract

An adjustable cushion support device for adjusting the holding pressure applied to support a seat cushion. The adjustable support device includes a frame member having a first end and a second end to support the cushion. A spring member is mounted on the frame member between the first end and the second end for flexibly supporting a load. A control mechanism is mounted on the frame member and is connected to the spring member for adjusting the holding pressure applied to the spring member. The control mechanism includes an enforcing member pivotally supported on the frame member for pushing the spring member upwards, a biasing member for biasing the enforcement member, and an operating lever to control the inclination of the biasing member to regulate the holding pressure applied to the spring member.

Claims

1. An adjustable cushion support comprising:

a cushion;

a frame member for supporting said cushion;

spring means mounted on said frame member for directly supporting said cushion;

holding means connecting said spring means to said frame member for flexibly holding said spring means; and

control means mounted on said frame member and connected to said spring means for adjusting the holding pressure applied to said spring means, said control means including;

enforcement means pivotally supported on said frame member for pushing said spring means upward, said enforcing means having a first arm portion connected to said spring means and a second arm portion;

biasing means connected to said second arm portion for maintaining the holding pressure applied by said enforcement means to said spring means; and

an operating lever mounted on said frame member and having a control arm connected to said biasing means and movably positioned along said frame member to control the inclination of said biasing means, thereby regulating the holding pressure applied to said spring means, said operating lever also having arresting means for affixing said operating lever to said frame member.

2. An adjustable cushion support according to claim 1, wherein said first and second arm portions are integrally connected to form a substantially v-shaped crank, said first arm portion of said crank having a first tip and said second arm portion of said crank having a second tip connected to said biasing means.

3. The adjustable cushion support defined in claim 1, wherein said forward holding means includes a front frame pivotally attached to said bar means and said spring means includes a series of serpentine springs secured to said front frame proximate said front portion of said frame member.

4. An adjustable cushion support comprising:

a cushion;

a frame member for supporting said cushion and having a front portion and a rear portion;

bar means extending between opposite sides of said frame member proximate said front portion;

support means mounted on said frame member between said front portion and said rear portion for flexibly supporting a load imposed thereon, said support means including;

spring means for directly supporting said cushion;

forward holding means connecting said spring means to said bar means for holding said spring means to support said cushion and for limiting movement between said support means and said frame member; and

rearward holding means connecting said spring means to said rear portion for holding said spring means to support said cushion and for limiting movement between said support means and said frame member;

control means mounted on said frame member and connected to said support means for adjusting the holding pressure applied to said spring means, said control means including;

a rotatable operating lever;

plate means connected to said frame member and operatively connected to said operating lever for movement therewith;

biasing means extending between said plate means and said support means for maintaining the holding pressure applied to said spring means depending upon the inclination of said biasing means; and

engagement means formed along said plate means for adjusting the inclination of said biasing means in response to said operating lever, thereby regulating the holding pressure applied to said spring means.

5. The adjustable cushion support defined in claim 4, wherein said rearward holding means includes:

a rear frame, said serpentine springs being secured to said rear frame proximate said rear portion of said frame member;

arm sections extending between said rear frame and said rear portion; and

retention means for pivotally attaching said arm sections to said rear frame.

6. An adjustable cushion support comprising:

a cushion;

a frame member to support said cushion and having a first end and a second end;

support means mounted on said frame member between said first end and said second end for flexibly supporting a load imposed thereon;

control means mounted on said frame member and connected to said support means for adjusting the holding pressure applied to said support means, said control means including;

a rotatable operating lever, having arresting means for affixing said operating lever to said frame member;

plate means connected to said frame member and operatively connected to said operating lever for movement therewith;

biasing means extending between said plate means and said support means for maintaining the holding pressure applied to said spring means depending upon the inclination of said biasing means; and

engagement means formed along said plate means for adjusting the inclination of said biasing means in response to rotation of said operating lever, thereby regulating the holding pressure applied to said spring means.
