Abstract

An airbag module of a safety device for vehicle occupants includes a temperature sensor. Output terminals of the temperature sensor are each connected via leads to one input terminal each of a firing element.

Claims

1. An airbag module comprising:

an inflatable airbag;

a gas generator;

first and second firing elements for activating the gas generator and, in turn, for inflating the inflatable airbag, in response to at least one signal from a control unit, the first and second firing elements having first and second input terminals, respectively; and

a temperature sensor having first and second output terminals coupled to the first and second input terminals, respectively, of the first and second firing elements.

2. The airbag module according to claim 1, wherein the temperature sensor is disposed inside the airbag module.

3. The airbag module according to claim 2, wherein the temperature sensor detects an ambient temperature in a vicinity of the airbag.

4. The airbag module according to claim 1, wherein the temperature sensor is arranged in close proximity to at least one of the first and second firing elements.

5. The airbag module according to claim 1, wherein the temperature sensor is combined with the first and second firing elements to form a common subassembly.
