Abstract

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.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 102 words
A thermic protection device for vehicle lighters in which an electric contact holder base (16) is provided with a contact spring (11) and a first bimetallic lamina (15) for thermic protection against superheating that causes a short circuit allowing a lighter to be reutilized, characterized in that a base (16) is fitted with a second bimetallic lamina (18) for thermic protection that remains abut against a resistor (12) of the lighter's plug (10) when the plug (10) is pressed into the base, maintaining the electric contact of the resistor (12) until at least the first lamina (15) deflects in response to heating.
Claim 2
Dependent Claim 102 words
A thermic protection device for vehicle lighters in which an electric contact holder base (16) is provided with a contact spring (11) and a first bimetallic lamina (15) for thermic protection against superheating that causes a short circuit allowing a lighter to be reutilized, characterized in that a base (16) is fitted with a second bimetallic lamina (18) for thermic protection that remains abut against a resistor (12) of the lighter's plug (10) when the plug (10) is pressed into the base, maintaining the electric contact of the resistor (12) until at least the first lamina (15) deflects in response to heating.
Claim 3
Dependent Claim 23 words
A device according to claim 1, characterized in that the two thermic protection laminas (15, 18) are obtained from the same bimetallic strip.
Claim 4
Dependent Claim 23 words
A device according to claim 1, characterized in that the two thermic protection laminas (15, 19) are obtained from two separate bimetallic strips.
