Abstract
A kit for adding a reclining seat to a wheelchair, comprising a stationary seat frame for mounting to a base frame of the wheelchair, a seat for mounting to the stationary seat frame, the seat having a seat portion and a back portion pivotally mounted to said seat portion, and an actuator mounted on the seat for causing the back portion of said seat to change angle relative to said stationary seat frame, a sliding connector for slidably mounting said seat portion to said stationary seat frame, and means for sliding said seat on said stationary seat frame along said sliding connector without changing height as the actuator causes the angle of the back portion to change, wherein said kit, when mounted on a wheelchair, compensates for a change in an occupant's center of gravity by sliding said seat portion on said stationary seat frame as said back portion changes angle.
