Backup energy storage element for airbags

Why do airbags have energy reserve capacitors?

The energy reserve capacitors used in the ACU (Airbag Control Unit) are provided so that once a crash event occurs and Loss of Battery (LOB) occurs in turn, the airbags can still be powered with their help as an emergency supply system.

How do airbag modules work?

Airbag modules are continuing to evolve and proliferate. Most of these devices are similar in that they take an electrical signal from the vehicles crash sensing system, activate, or ignite, an inflator to rapidly produce an inert gas, use that gas to fill a cushion, which then provides energy absorption to the vehicle occupant(s).

The general types of airbag modules include:

Are airbag modules pyrotechnic devices?

In this context, we refer to all airbag modules and pre-tensioning seatbelts as being pyrotechnic devices. Spent Device – An inflator, airbag module, or pre-tensioner that no longer contains any energetic materials and is commonly referred to as inert. 3. General Information

How much energy does an airbag use?

The total energy input to the airbag is not shown in pended in moving the torso is only about 0.3%(0.Q37 kJ) of the figure in order to give a clearer picture of the energy the total energy delivered into the bag (12.16 kJ). AVAILABLE WORK IN DRIVER AIRBAG Values of when the offset of the torso is small.

How do you store a live airbag module?

Always store a live module in its approved shipping container when available. Store live modules in a cool, dry, secure area away from all corrosives, oxidizers, ignition sources, or high heat sources. Curtain type airbags should be stored lying as flat as possible and unfolded. Always store airbag modules with the cover facing up not down.
