Plug-In Vest Heats From Dashboard

April 1963…

Plug-in vest heats from dashboard.

Riders in open cars, boats, tractors, or on motorcycles can now keep warm on cold days, says the inventor of this plug-in vest.

It has flexible heating elements enclosed in plastic front and back panels and it plugs into a cigarette-lighter receptacle connected to a 6, 12, or 24-volt battery.

Normally worn inside the jacket, the French device is demonstrated above on a cold day in London. When not in use the plug can be tucked in a pocket.
