## Abstract

A pneumatic lounging system includes an inflatable support unit and an inflatable unit. The inflatable support unit includes an inward layer, an outward layer, and a support air nozzle. The inward layer and the outward layer define an air cavity, and the outward layer is attached to the inward layer. The support air nozzle is attached and adapted to provide direct fluid communication of air with the air cavity. The inflatable unit includes an inward wall, an outward wall, and an air nozzle. The inward wall and the outward wall define at least one air chamber, and the inward wall is attached to the outward layer. The air nozzle is adapted to provide direct fluid communication of air with one of the at least one air chamber. There is no fluid communication between the inflatable support unit and the first inflatable unit.

## Claims

### Claim 1

A pneumatic lounging system comprising:
an inflatable support unit including:
an inward layer and an outward layer defining an air cavity, wherein the outward layer is attached to the inward layer, and
a support air nozzle attached and adapted to provide direct fluid communication of air with the air cavity; and
a first inflatable unit including:
an inward wall and an outward wall, wherein the inward and outward walls define at least one air chamber and the inward wall is attached to the outward layer, and
an air nozzle adapted to provide direct fluid communication of air with one of the at least one air chamber, wherein the fluid communication of air with the air cavity is independent of the fluid communication of air with the at least one air chamber.

### Claim 2 (depends on 1)

The pneumatic lounging system set forth in claim 1, wherein the first inflatable unit includes a plurality of stacked air cells each including an inward wall and an outward wall, the inward and outward walls of each air cell defining an air chamber, at least one orifice adapted to provide fluid communication between respective chambers of adjacent air cells of the plurality of stacked air cells.

### Claim 3 (depends on 2)

The pneumatic lounging system set forth in claim 2, wherein each orifice of the at least one orifice includes a first inner perimeter defining an opening in an outward wall of an inward air cell and a second inner perimeter defining an opening in an inward wall of an adjacent outward air cell, the first and second perimeters being attached, and the openings being aligned to provide fluid communication between the inward and outward air cells.

### Claim 4 (depends on 3)

The pneumatic lounging system set forth in claim 3, wherein the first inflatable unit is accordion-like.

### Claim 5 (depends on 1)

The pneumatic lounging system set forth in claim 1, wherein the first inflatable unit is a first inflatable massage unit.

### Claim 6 (depends on 3)

The pneumatic lounging system set forth in claim 3, wherein an outer perimeter segment of the inward wall and an outer perimeter segment of the outward wall of each air cell of the plurality of air cells are attached forming a continuous outer perimeter seam.

### Claim 7 (depends on 3)

The pneumatic lounging system set forth in claim 3, wherein an outer perimeter portion of the inward layer and an outer perimeter portion of the outward layer are attached forming an outer perimeter layer seam.

### Claim 8 (depends on 7)

The pneumatic lounging system set forth in claim 7, wherein an outer perimeter segment of the inward wall and an outer perimeter segment of the outward wall of each air cell of the plurality of air cells are attached forming an outer perimeter wall seam.

### Claim 9 (depends on 7)

The pneumatic lounging system set forth in claim 7, wherein the outer perimeter layer seam is sonic welded, and the inward and outward layers are made of resiliently pliable plastic.

### Claim 10 (depends on 1)

The pneumatic lounging system set forth in claim 1, further comprising:
a second inflatable unit including:
an inward wall and an outward wall, wherein the inward and outward walls define at least one air chamber and the inward wall is attached to the outward layer, and
an air nozzle adapted to provide direct fluid communication of air with one of the at least one air chamber, wherein there is no fluid communication between the inflatable support unit and the second inflatable unit.

### Claim 11 (depends on 10)

The pneumatic lounging system set forth in claim 10, wherein the first and second inflatable units are inflatable massage units.

### Claim 12 (depends on 11)

The pneumatic lounging system set forth in claim 11, wherein the inflatable support unit is a shoulder support unit and the first and second inflatable massage units are left and right side massage units.

### Claim 13 (depends on 1)

The pneumatic lounging system set forth in claim 1, further comprising
an automotive seat structure adapted to support the inflatable support unit.

### Claim 14

An automotive seat comprising:
a seat structure;
an inflatable support unit adapted to adjustably support at least one of a lumbar, a neck, and a shoulder; and
a first inflatable unit including:
an inward wall and an outward wall, wherein the inward and outward walls define at least one air chamber and the inward wall is directly attached to the inflatable support unit, and
an air nozzle adapted to provide direct fluid communication of air with one of the at least one air chamber, wherein there is no fluid communication between the inflatable support unit and the first inflatable unit.

### Claim 15 (depends on 14)

The automotive seat set forth in claim 14, further comprising:
a second inflatable unit laterally spaced from the first inflatable unit, the second inflatable unit including:
an inward wall and an outward wall, wherein the inward and outward walls define at least one air chamber and the inward wall of the second inflatable unit is directly attached to the inflatable support unit, and
an air nozzle attached and adapted to provide direct fluid communication of air with one of the at least one air chamber, wherein there is no fluid communication between the inflatable support unit and the second inflatable unit.

### Claim 16 (depends on 15)

The automotive seat set forth in claim 15, wherein the first and second inflatable units are massage units.

### Claim 17 (depends on 16)

The automotive seat set forth in claim 16, wherein the inflatable support unit is an adjustable shoulder support unit, and the first inflatable massage unit is generally a left shoulder massage unit, and the second inflatable massage unit is generally a right shoulder massage unit.

### Claim 18 (depends on 16)

The automotive seat set forth in claim 16, wherein the first and second inflatable units are each accordion-like including a plurality of stacked air cells each defining an air chamber, at least one orifice positioned between adjacent air cells of the plurality of stacked air cells for fluid communication between chambers.

### Claim 19 (depends on 18)

The automotive seat set forth in claim 18, wherein the plurality of stacked air cells include an inward air cell attached to the inflatable support unit, and an outward air cell attached to and in fluid communication with the inward air cell.
