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.
