Is there a difference between SRS and airbag?

modern setup vehicle has SRS airbags.





what makes a diference if there's no SRS, but just purely airbag. can this be possible?





thanks|||SRS means "Supplimental Restraint System"





This is the terminology made common by European manufacturers.





Seat belts are Primary Restraint Systems...not Supplimental.





The automative seatbelts of the early '90's are PASSIVE Restraint Systems...but not Supplimental. They are not supplimenting anything.





American car manufacturers used them because they had to have a passive restraint...airbags are always Passive...but the seat belts were an alternative until new designs incorporated airbags.





American car manufactures used to call Airbags SIRs instead of SRSs. That stood for Supplimental Inflatable Restraint.





All frontal airbags are passive, supplimental inflatable restraints. Don't get confused by the terminology.





New cars tend to just call them "airbag" for simplicity...your question is a perfect example as to why.|||SRS is Supplemental Restaint System. One type, the overwhelming favorite, is airbags.





An airbag is an SRS, but an SRS can be something else, like those automatic seatbelts of the late 80's and early 90's. Knee bolsters are SRS's as well. They're built into the dash assembly to keep you from submarining into the footwell and being crushed.|||I was looking over a Honda Civic I bought recently and it lables both airbags as SRS. According to the label it is something like "Secondary Restraint System" or "Safety Restraint System". It was late and I didn't pay much attention but think it was one of the two. Basically SRS is just what they are calling the airbags...same thing.|||No. Of course you might have multiple airbags.





It's always a SYSTEM because it needs sensors and activators, typically mounted under the front bumper.|||All passenger car airbags are SRS. It means supplemental restraint system. This means that it must be used only as a supplement to the primary restraint system, which is the seat belts. In other words, it must be used IN ADDITION TO seat belts, and not instead of seat belts.
