Abstract
A method for manufacturing an inflatable cushion of utility as a jack. The cushion is made from a piece of fabric coated with elastomer and comprising a polygonal bottom wall and a top wall which includes triangular portions between which are circumferentially interposed gores. The top wall is formed by folding over the triangular portions onto the bottom wall and securing the gores to the triangular portions, as by an adhesive or vulcanization. If desired, a reinforcing and retaining disc can be secured to the outer and/or inner face of the upper wall. A center inflating valve may be secured to the center of the upper wall.
