Abstract
To assist a person from seated to an erect position a mechanism for raising and straightening a seat surface and the seat backrest to a nearly vertical position is provided, which avoids substantial relative motion between the body of the person and the seat surface and the seat backrest. In the erected position of the chair, a groundplate of the footrest is firmly supported on the ground.
