AIR BAG (SUPPLEMENTAL RESTRAINT SYSTEM)
The Supplemental Restraint System (SRS) is designed to work in conjunction with the standard three-point safety belts to reduce injury in a head-on collision.
The SRS can actually cause physical injury or death if the safety belts are not used, or if the manufacturer's warnings are not followed. The manufacturer's warnings can be found in your owner's manual, or, in some cases, on your sun visors.
Depending on your vehicle, the SRS may be comprised of some or all of the following components:
- Driver's side air bag module
- Passenger's side air bag module
- Air bag diagnostic monitor computer
- Left and right-hand radiator primary crash air bag sensor and bracket
- Center cowl safing rear air bag sensor and bracket
- Left-hand kick panel safing rear air bag sensor and brackets
- Air bag warning indicator
- Tone generator (internal to the air bag diagnostic monitor)
- Electrical wiring
- Air bag Electronic Crash Sensor (ECS)
The sensors in the car are designed to detect a severe frontal impact. When at least one of the primary crash sensors and the center cowl safing rear air bag sensor close at the same time, electric current flows to the inflator and ignites the chemicals.
The chemicals burn rapidly in the metal container. This burning produces nitrogen gas and small amounts of dust, both the gas and dust are cooled and filtered during the air bag(s) inflation.
The air bag(s) split the trim covers open while inflating. The air bag(s) then rapidly unfold and inflate in front of the driver or passenger.
After the air bag(s) have inflated, the gas escapes through holes in the bag(s) and the they will deflate.
