Abstract: Hot bowl of a cigarette lighter body in particular of the type mounted on motor vehicles, its perimetral surface comprising a bendable lug which pinches one end of the spiral resistance element contained within the lighter by a crimping process.

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.

Abstract: An electric contact holder base for electric lighters or other gadgets for motor vehicles is provided with a thermic protection against overheating that allows its reutilization. The base has a substantially cylindrical body, permanently fixed in the passenger's cabin and carries electric contacts for the gadget that is inserted in said cylindrical body. At least a bimetallic spring acts as a holding element of the lighter in the cylindrical body during the resting phase of the same. A bimetallic lamina is the thermic protection device against overheating; this is a separated element, connected at one end with an electric contact, while the other end is facing the wall of the cylindrical body and folded back towards its bottom.
