Crashed city, but airbags did NOT deploy??

[mbt]

chanced upon this wrecked Honda City in a Honda service bay, and it seems like a reasonably heavy crash. heck, there were even small bloodstains on the left side of the front passenger seat.



but why didnt the airbags deploy, as can be clearly seen in the photo?

ang dami ko na atang nakikitang (o nababalitaan na) crashed vehicles na hindi nagdeploy yung airbags?? there was this totalled cr-v in a dealer before that had a messed front end and the airbags didnt seem to have deployed too...?

[wilcats]

dude bka yang city eh wlang ABS/SRS option... meron ganun naman eh

I agree. Kahit na nakalagay sa steering wheel "SRS" logo, it doesnt mean na may airbag sa loob ito. Its more reasonable to use the same type of steering wheel with or without SRS as opposed to designing a new steering wheel without Airbag SRS. Eto naman eh kung optional nga ang Airbag SRS sa Honda City sa Pinas.

And looking at the damage, it seems like the bumper support and/or the front of the chassis sustained a significant amount of impact for the airbag to deploy if so equipped.

faulty sensors?

[airshaq20]

Well....there are 3 basic parts of an airbag.
1. First, there is the bag itself, which is made of thin, nylon fabric and folded into the steering wheel or the dash board.

2. The sensor that tells the bag to inflate. It detects a collision force equal to running into a brick wall at 10 to 15 miles per hour (16 to 24 kph).

3. The inflation system. Air bags are actually inflated by the equivalent of a solid rocket booster. Sodium azide and potassium nitrate react very quickly to produce a large pulse of hot nitrogen gas.


So my conclusions:
1. Car may not have airbag (i believe its still optional with most cars in the Philippines)
2. Defective sensors
3. Airbag light was "on" prior to this accident. Even if you have an airbag, if you have the Airbag light on from the dash, your airbag/s will not inflate when its supposed to.
4. From the pictures, it seems that its not from a high speed (or else, the car should be totalled) - airbags deploy from certain impacts, angle of impact and speed upon impact. Sensors use logics - not common sense.

true. indicated din at the manual the typical situations when the airbags would deploy. typical exceptions include rollovers, t-bone impacts...

we're talking about the standard driver and passenger bags, not the SIPS or additional airbags ah. :D

[Karding]

Lets use Toyota's diagram as a reference of when or what certain situation an airbag deploys, compare natin ang damage ng City sa itaas.



Concrete collision * 20km/h:

[mbt]

this CVT model has airbags, here's a 100% crop (from the 5 MP image) of the steering wheel hehe

[Karding]

Poles collision * 30km/h:


Head-on collision * 40km/h:

[Karding]

Hindi nga yata ganon kalakas ang impact since a 40mph (64km/hr) crash typically looks like this:



And according to the Insurance Institute for Highway Safety, "40 MPH FRONTAL OFFSET CRASH TESTS are a good measure of a vehicle's structural design."

[nugundam93]

so the city was probably running about 50kph?

[Karding]

maybe less dahil eto naman ang 30mph (50kph) concrete crash test:



notice the crumpled hood.

[nugundam93]

ahhhh okay. onga, the city's front supports weren't that much bent...

seen already two mishaps na the airbags did not deploy, one sa gen 1 rav4 which was in an accident twice! first headon sa post second head on sa isang pick-up, this is the same car lang first accident airbags did not deploy, sabi namin mag file case against the manufacturer, then pinaayos sa casa, second accident headon sa isang pick-up wala pa rin, swerte daw car i hindi siya namatay.

second incident is a d-max, front end was not damaged but the windshield and roof was it did not see the parked truck so maybe the sensors were not or did not detect the crash.

others would say na iba daw ang sensitivity ng sensors for airbags for Phil market due to the fact na sometimes we might bump tricycles and it might trigger the sensor!

[ghosthunter]

what kind of sensor is the City using?

[BlueBimmer]

hmm so this leads to false sense of security for some passengers cos they dont know the proper spec of the airbags..'basta may airbags safe na' ang nasa isip

Yes. You should never depend on airbags alone for protection. That's why they are called 'SRS'. The first S being 'SUPPLEMENTAL'. They are just there to supplement the seatbelts and other safety features of the vehicle. They will not always deploy especially when the seatbelts will already offer enough protection for the given event (to lessen repair costs, mahal mag-reset ng airbag).

They are not magic ballons that will softly and gently catch you everytime you decide to hit something.

Not all types of crashes will deploy airbags.

[MAXBUWAYA]

thats crap! I think airbags are activated by speed 20km above.

Hmmmm baka maraming airbag na faulty or kulang sa pyesa ang kinakabit. Baka ABS din!

Sa US alam ko may value ang airbag at ninanakaw din parang stereo.

Baka tinira ng CASA>?

[OTEP]

It doesn't look like a high-speed crash to me. The airbag is triggered by speed ang g sensors. Not enough of each = no deployment.

i've seen an 03 CRV with deployed airbags (light blue yung color ng 'cloth'), medyo nakainom kasi yung nagddrive when the accident occurred. my guess is its travelling above 80kph when it slammed into the rear of a bus.

yung gen1 crv ko dati, nagkaroon ng sira yung parang actuator yata. hindi na kasi nawawala yung SRS na indicator. it costed me around 21K to have it replaced!
