Title: Question about passenger airbag
Post by: Arabas on May 15, 2012, 06:21:25 AM
is there a way to have the passenger airbag ALWAYS ON?

our cars' passenger airbag  work with a weight sensor, but it will turn it on only when someone over 50kg or something like that sits on. my problem is that my wife is on the very edge of this kilos and there are long periods that the passenger airbag will not turn on, which of course i find as a problem.

is there a simple way to bypass the sensor?

PS to kappa drift team: NO, i will not tell my wife to gain weight neither will i change wife to resolve the problem

I would think if you pulled the sensor from the seat and clamped it together with vice grips or some clamp, it would always leave the airbag on.

However a downfall to getting the airbag on all the time would be when she is not in the car, you will have to buckle the passenger seatbelt, or listen to the alarm chime that no seatbelt is on. (unless you do the chime removal which was just posted in skyroadster)

Of course if she just sat in the seat properly, you wouldn't have any issues.

this actually worked for some time, but now she seems to have lost weight and the purse won't do the trick...

If elff can keep his airbag sensor on with himself and his wife, I dont think I want to know how small your wife is.

btw did anyone tell you inflatable wives dont count?

This is an excellent reason for her to get some better posture. because from what you describe, she is on a gangsta lean.

 :lol: :lol:

well, she' s taller than me but also quite thin. when she starts eating, she just can't stop, but she won't get any weight at all.
i was on a diet for the last two months, so she kind of supported me (meaning no sweets, no junk food) and as a result she lost weight.
it bugs me that the kappas don't have a key operated on/off switch for the passenger seat belt like other cars and instead they have these silly weight sensors...

My best friend from college is like that. Her whole family is like that! She can eat all day long and weighs 100 lbs on a good day!  She's like 5'-6".

I thought the airbag would turn on for less than that though.  *nope*  found it on the Solstice forum and it says depends on position and weight distribution.  Probably triggers somewhere around 90-115 lbs depending on how someone sits in the seat.

Which is interesting because I use to weigh about that in my early 20's and I don't remember not triggering the sensor.

Mine kept going off last weekend, took me a moment to realize a bag of soil and some plants was activating it.

I have no problems with Arabas' wife in my car.  Strange, I'm guessing his sensor is bad. Kelu, have you ever had that problem with Arabas' wife in you car?

The reason the airbag triggers at the weight it does is for child safety, as the airbag deploying can be more harmful to small children than no airbag during an accident.  The weight limit doesn't take into account tall, thin women.

From what I recall of previous discussions about this issue, the best solution is to have your wife sit down "heavily" in the seat. What I mean by "heavily" is to drop down hard in the seat from and directly from above rather than sitting down gently and sliding into the seat like a lady.  This should help the sensor sense her in the seat.

Based on your age I didn't think cars came with weight sensors for the airbags back then. (ducking) :D

But in all seriousness, air bag suppression based on passenger size/weight wasn't required to be standard in all cars until 2006, with the law requiring carmakers to phase it into production sometime around 2002. Prior to that date, airbag suppression for the passenger seat was optional and probably only available on certain cars, so in your 20's whatever car you were riding around in as a passenger may not have had this feature.

Quote from:  some random paper about airbags I found on the internet
The introduction of airbags into automobiles has significantly improved the safety of the occupants. Unfortunately, airbags can also cause fatal injuries if the occupant is a child smaller (in weight) than a typical 6 year old. In response to this, The National Highway Transportation and Safety Administration (NHTSA) has mandated that starting in the 2006 model year all automobiles be equipped with an automatic suppression system to detect the presence of a child or infant and suppress the airbag.
...
In May 2001 the U.S National Highway Transportation and Safety Administration (NHTSA) defined the Federal Motor Vehicle Safety Standard (FMVSS) 208 that mandates automatic airbag suppression when an occupant smaller than a 6 year old child is in the passenger seat.

Could be. I remember all the cars we had from 1995 on had passenger air bags. But I don't remember if they had the sensor or not. Prolly not.

Not at all buddy, maybe that is the reason for them not coming to Romania as last call which would reveal Arabas' sensor is faulty  :lol:  :lol:  :lol:

On a different note, did you investigate how that sensor triggers? Did you thought to put something between seat and sensor which might increase the "weight" overall?
I'm thinking to something like this:

The sensor is just a weight sensitive switch isn't it?  Why not just wire a toggle switch in parallel to the sensor so you can turn it on when you want and to use the sensor at other times?

Keep a 5lb dumbell in the trunk and when the wife comes along she will have to work on her arm curls

I really don't think Arabas has a problem
He is just bragging about how hot his new wife is

I can't blame the guy

I think Kelu's idea or the switch as suggested by Sol Asylum would do the trick.

Hell, they didn't have seat belts and kids used to ride in the package tray behind the seat.

Umm...they did.  I'm not that old.  I was 22 and owned a 1995 Cavalier Z24 with driver and passenger air bags.

Suddenly I am feeling a lot younger.

Elff what makes you think Critter was running from the dinosaurs?  They are extinct for a reason.

Arabas, since you are in honeymoon mode anyway, may I suggest checking out the kappa sutra action in the thread http://www.kappaperformance.com/forum/index.php/topic,7921.0.html (http://www.kappaperformance.com/forum/index.php/topic,7921.0.html) .   I'm sure lots of positions will change the pressure points enough to trigger the airbags on... though I'm not sure you'd like them to go off at certain times.

Are the airbags supposed to go off from a rear end collision?

Sorry he's Greek, I had to ask.

Yes I think I heard something about Greek safety standards requiring the air bags deploy with a rear end collision, (for pillow biting purposes) as well as the car automatically shifts to R.... strange these safety standards...

Most sensors detect some sort of voltage change.  To enable the passenger airbag to be on all the time, you could place wire taps on the two wires going to the sensor and take a reading with a volt meter with the seat empty and then with someone sitting in the seat who is heavy enough to activate the airbag sensor.  Then you could add a resistor(you would have to calculate the resistor needed) between the taps on the two wires that would send to correct voltage to the computer that would activate the sensor.

It may be even simpler than that if the sensor is just an on/off contact switch.  If so, then you would only need to splice in a piece of wire between the two sensor wires.

Basically, you are tricking the computer.

Yes.  There is no way to do that.

I wrote a post on decomposing the sensor system... don't have the links with me (out of town) but you could search.
