Abstract
A seat forming apparatus for use in a downhole tool comprising a driving member and a seating restriction. The driving member and the seating restriction are mechanically disposed within an outer housing of the downhole tool. When the driving member drives into the seating restriction, the seating restriction or the driving member bend or buckle inwards to form a seat in the downhole tool. The inner diameter of the seat is configured to allow a restriction element to be seated in the seat.
