Abstract

An electrically heated portable seat for automobiles includes a flexible and liquid-impervious container having spaced top and bottom surfaces, a sponge-like material bonded to the inner surface of the container, a liquid absorbed in the sponge-like material, and an electrical heating element for heating the liquid inside of the container. The seat is plugged into a wall outlet in a house just before its use. After the seat is warmed up, it is carried to a car and placed on the car seat.

Claims

1. A portable seat comprising,

a flexible and liquid-impervious container having spaced top and bottom surfaces,

a sponge-like material in the container,

bonding means for creating permanent bond between the outer surface of the sponge-like material and the inner surface of the container,

a liquid absorbed in the sponge-like material, and

an electrical heating element for heating the liquid inside of the container.

2. The portable seat of claim 1 wherein at least a portion of the outer surface of the sponge-like material is bonded to the inner surface of the container.

3. The portable seat of claim 1 wherein the heating element has a temperature control device.

4. The portable seat of claim 1 wherein the container is partially filled with liquid.
