Abstract:
1. A device for seat elevation, the device comprising: a seat base having a substantially planar seat portion and vertical seat supports positioned substantially perpendicular to the planar seat portion; an elongated lift generator having a longitudinal axis, a top portion, a bottom portion, and in connection with the vertical seat supports, wherein the lift generator is substantially positioned at an angle from a floor at all times during use with its bottom portion closest to the floor; and a horizontal base portion fixedly connected to a substantially vertical support portion; wherein the vertical support portion has a first and a second substantially rigid and linear elongate members pivotally connected, the first member near a top point of the vertical support portion and the second member near a middle point of the vertical support portion, the first member extending horizontally, connecting to the lift generator and connecting pivotally to a point of the vertical seat support, and the second member extending at a downward angle from its connection with the vertical support portion and connecting pivotally to a lower point of the vertical seat support than the first member; wherein the lift generator moves the first member which then moves the seat portion in a direction parallel to the longitudinal axis of the lift generator, from a first position in which the seat portion is substantially horizontal to a second position that is different in vertical, horizontal and rotational tilt placement from the first position such that the seat portion is closer to the vertical support portion and is substantially perpendicular to the longitudinal axis of the lift generator.
