Devices and Methods for Body Elevation

摘要

Devices and methods are presented for elevating seat devices. The device allows a vertical and forward motion of a seat from a first position to a second position. Such motion more resembles a natural body motion during the standing motion. A similar but converse motion is also possible with movement from a standing position to a sitting position.

主权项

1. A device for seat elevation, the device comprising:
a horizontal base portion fixedly connected to a substantially vertical support portion; a lift generator that extends and contracts along a longitudinal axis, the lift generator pivotally connected to the horizontal base portion; a plurality of members pivotally connected to the vertical support portion, the plurality of members including a first member pivotally connected to the lift generator on a first side of the horizontal base portion; a drive shaft coupled to the first member connecting the first member to a second member on a second side of the horizontal base portion, the drive shaft transferring rotational force delivered by the lift generator from the first member to the second member; and a seat portion attached to a plurality of vertical seat supports positioned substantially perpendicular to the planar seat portion, the plurality of vertical seat supports pivotally connected to the plurality of members; wherein as the lift generator extends, the plurality of members guide the motion of the seat portion in a direction substantially parallel to the longitudinal axis of the lift generator from a first position, in which the seat portion is substantially horizontal and substantially centered over the base portion, to a second position, in which the seat portion is substantially perpendicular to the longitudinal axis of the lift generator and centered closer to the vertical support portion.
