ABSTRACT:
A tilt chair having a foot adapted to be supported by a support surface and a first leg pivotally mounted to the foot. A second leg is pivotally mounted to the first leg. A moveable support member is mounted to the second leg and is adapted to be supported by the support surface. The moveably support member is moveable in a first and second direction toward and away from the foot respectively as the first leg pivots relative to the second leg and as the first leg pivots relative to the foot. In one embodiment, the moveable support member is configured as a wheel. In one embodiment, a lower back member has a lower end pivotally mounted to the first leg and an upper back member pivotally mounted to an upper end of the lower back member. A restraining link is pivotally mounted between the lower back member and the second leg. An upper back link has a lower end pivotally mounted to the first leg and an upper end pivotally mounted to the upper back member. An actuator is operably connected to the first and second legs. A seat support is connected to the second leg, and one or both of an armrest and worksurface are mounted to the seat support. A method of tilting the chair is also provided and includes pivoting the second leg relative to the first leg and thereby rolling the wheel on the floor and pivoting the first leg relative to the foot.
