ABSTRACT:
A thermic protection device for vehicle lighters in which the electric contact holder base (16) is provided with a first bimetallic lamina (15) for thermic protection against superheating that causes a short circuit allowing the lighter to be reutilized.
The base (16) is fitted with a second bimetallic lamina (18) for thermic protection that remains abut against the resistor (12) of the lighter's plug (10) when this is pressed into the base, maintaining the electric contact until at least the first lamina (15) is started up.
