Abstract
Abstract A collapsible infant seat and stroller includes a central frame support having straps so that the frame may be carried as a backpack. A lower part of the frame includes wheels which may be moved between a first inactive position and a second active position. A handle-bar is provided which is pivotably attached to the upper part of the frame so that it may be positioned in a folded position, so that its length is adjacent the length of the frame, and a handle-bar position so that the frame may be pushed along the ground by means of the wheels. A seat is provided which is supported by a seat support member which is pivotably fixed to the upper part of the frame so that the seat may be positioned in an active position and an inactive position. A stabilizing leg is also provided so that the device may be used as a stationary seat.
