when did they put air conditioning in cars
Automobile air conditioning In 1939, Packard became the first automobile manufacturer to offer an air conditioning unit in its cars.[2] These were manufactured by Bishop and Babcock Co, of Cleveland, Ohio. The "Bishop and Babcock Weather Conditioner" also incorporated a heater. Cars ordered with the new "Weather Conditioner" were shipped from Packard's East Grand Boulevard facility to the B&B factory where the conversion was performed. Once complete, the car was shipped to a local dealer where the customer would take delivery.
Airbag The airbag specified for automobile use traces its origins to air-filled bladders as early as 1951.[9][10]
