Abstract
Abstract A unit handled air cell assembly or module is mounted on a backplate or other suitable support of an automotive seat back. The module comprises an air cell, an electric motor driven air pump, a solenoid valve and a reversible electric pigtail for connecting the electric motor and the solenoid valve to a control circuit. The electric motor driven air pump is disposed inside the air cell and operatively connected to an air tube that extends out of the air cell. The solenoid valve is connected to the exterior end of the air tube to control the flow of air to and from the air cell. The electric motor driven air pump is shaped so as to fit in a cut-out of the back plate or support and avoid discomfort to the seat occupant. In a second embodiment, the electric motor driven air pump is disposed in a plastic sleeve that is attached to the air cell and the solenoid valve is attached to the outlet end of the air pump.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
146 words
A unit handled air cell module comprising: a flexible backing member having a membrane secured to it to form an air cell, an air tube extending through a wall of the air cell, an electric motor driven air pump fluidly connected to the air tube, a solenoid valve fluidly connected to the air tube to control the flow of air to and from the air cell, and an electric pigtail having electric leads for the electric motor driven air pump and the solenoid valve and an electrical connector for connecting the electric leads to a control circuit having a remote electric power source and a remote control switch for operating the air cell module, a backplate of a seat back, said backplate having a cut-out, and said flexible backing member mounted on said backplate so that said electric driven air pump is disposed in the cutout.

Claim 4
Dependent Claim
43 words
The unit handled air cell module as defined in claim 1 wherein the electric driven air pump has a housing with flat sides and wherein the electric driven air pump is disposed in the cutout with the flat sides parallel to said backplate.
Claim 5
Dependent Claim
42 words
The unit handled air cell module as de-fined in claim 1 wherein the electric driven air pump is disposed in a sleeve attached to the air cell and the sleeve is disposed in the cutout along with the electric driven air pump.
Claim 6
Dependent Claim
158 words
A unit handled air cell module comprising: a flexible backing member having a membrane secured to it to form an air cell, a sleeve secured to the flexible backing member, an electric motor driven air pump disposed in the sleeve, a solenoid valve that is mounted on the electric motor driven air pump at one end and fluidly connected to an outlet of the electric motor driven air pump to control the flow of air to and from the air cell, an air tube fluidly connecting the solenoid valve to the air cell, and an electric pigtail that is attached to the electric motor driven air pump at the opposite end, the electric pigtail having electric leads for the electric motor driven air pump and the solenoid valve and an electrical connector for connecting the electric leads to a control circuit having a remote electric power source and a remote control switch for operating the air cell module.
