Inflatable packaging cushion

An inflatable packaging cushion comprising:

• a pair of substantially air impermeable sheet means of equal size;
• sealing means joining said pair of sheet means along their peripheries to form an impermeable air cushion;
• valve means secured to said cushion to permit air to enter and exit therefrom;
• means forming a plurality of compartments within the inflatable cushion;
• said pair of sheet means being in the shape of contiguous first and second rectangles;
• the compartments in said first rectangle forming a grid of columns and rows including marginal compartments, a central array of compartments and corner compartments;
• air passages connecting said central array of compartments and marginal compartments;
• said corner compartments being individually sealed in a deflated condition;
• the compartments in said second rectangle forming a grid of columns and rows including marginal compartments, a central array of compartments and corner compartments;
• air passages connecting the central array of compartments and marginal compartments in said second rectangle and connected to the air passages om said first rectangle;
• said marginal columns and rows of said first rectangle being adapted to be folded at right angles to said central array of compartments and said second rectangle being adapted to be folded over to a position parallel to the central array of compartments of said first rectangle.

An inflatable packaging cushion comprising:

• two substantially air impermeable rectangular sheet means of substantially equal size;
• sealing means joining said two sheet means along their peripheries to form an impermeable rectangular cushion;
• valve means secured to said cushion to permit air to enter and exit therefrom;
• means forming a plurality of compartments within the cushion in a rectangular grid of columns and rows;
• said grid of columns and rows including marginal compartments, a pair of central compartments and four corner compartments;
• air passages connecting said pair of central compartments and columns and rows of marginal compartments whereby air injected through said valve means will inflate said marginal compartments and at least a portion of each of said pair of central compartments;
• said corner compartments being sealed to remain in a deflated condition whereby the rows and columns of marginal compartments may be folded at substantially right angles to the central array of compartments ;
• and
• each of said pair of central compartments having a portion sealed off from the remained of the respective compartment whereby the said portion is noninflatable.
