The computer looks at the info fromt he impact sensors, sends voltage to the ignitor in the airbags, and the airbag "explodes".
Some of the safety features of the Volvo S40 are as follows; Anti-lock brakes, daytime running lights, center high mounted stop light, front impact airbags, driver side impact airbags, passenger side impact airbag, and overhead airbag. It also offers; occupancy sensor, side impact bars, seatbelt pretensioners, ignition disable, panic alarm, and a security system.
If the car is off and no one hits you the airbag should not deploy. If you are driving and stopped at a traffic light and someone hits you, the airbag could possibly deploy depending on the impact of the accident.
SRS (Supplimental Restraint System) aka Airbags dont have a set speed that they deploy... They deploy when jolted hard enough or have been strucked in an impact.
Airbags are termed supplemental restraints as they work with a number of other safety mechanisms within a car or vehicle. They operate by a series of steps to deploy the bag, first is that activation of crash sensors which being the engagement of the airbag, second this sends an electrical current to a squib, or inflater that casuses the igniter fluid to over heat and finnaly expands the airbag to take the impact of the passenger.
Airbags are passive safety devices that are designed to protect vehicle occupants in the event of a collision. They work in conjunction with seat belts to reduce the risk of injury during a crash. Here is a basic overview of how airbags work: 1. Sensors detect a collision: When a vehicle collides with an object, sensors located in the front of the vehicle detect the impact. 2. Signal is sent to the airbag module: The sensors send a signal to the airbag module, which is a computer that controls the airbag system. 3. Airbag is deployed: The airbag module activates an igniter, which generates a small explosion that rapidly inflates the airbag. 4. Airbag cushions the impact: The airbag inflates within a fraction of a second and cushions the impact of the occupant's head and chest as they come into contact with the dashboard or steering wheel. 5. Airbag deflates: Once the airbag has deployed, it begins to deflate as the gas inside it is released through small vents in the bag's fabric. It's important to note that airbags are designed to work in conjunction with seat belts, and are not a substitute for them. Seat belts are the primary safety device in a vehicle, and help to prevent occupants from being thrown forward and hitting the dashboard or other objects inside the vehicle. And our company, Oasis Bags is best for manufacturing air bags to consider peoples safetyness.
Airbags deploy at up to 300 km/hr.
Front Airbags: The first ones were installed for drivers and come out from the steering column. Some will have passenger-side front airbags. Side torso or window: These airbags cushion both front and rear passengers from the side. Torso airbags are usually in the rear seat and inflate between the passenger and his door; curtain airbags inflate across the window from the roof. Knee airbags: Designed to help prevent injury to the driver's legs. Rear: Rear curtain airbags cover the back window and rear center airbags cushion passengers from one another during an impact. Sometimes there are separate curtain airbags for front and rear passengers; sometimes one large curtain that runs the full length of the vehicle is installed.
Side impact airbags are there to reduce injuries to the head, neck and torso. Like front airbags they deploy instantly on impact. Side airbags deploy from the roof, door panels and seats. Furthermore, like front airbags the side airbags have reduced limb and torso injuries significantly and because of there safety record most new cars are now equipped with side airbags as standard equipment.
