Title: Portable lift seat apparatus

Abstract: A lift seat specifically suited for assisting an individual from a seated to a standing position or from a standing to a seated position. The lift seat has a hinged seat platform that is pivotally coupled with a base platform and a lift link assembly coupled to a wheeled carriage. The wheeled carriage is driven linearly by a motor powered lead screw that operates in either direction of rotation to advance the position of the carriage. The movement of the carriage in one direction causes the lift link assembly to raise the seat platform while the movement in the opposite direction causes the platform to lower.
