ONCA off-road products will not only improve your vehicles off-road capability, but will most definitely enhance your vehicles appearance as well!

Airbag compatability is a hot topic in the automotive industry and more specifically the 4 x 4 industry.  The perception amongst most people is that the airbag sensors are mounted in a vehicles front bumper. This is not the case, sensors are mounted next to the radiator as shown – (Hilux 2005 – 2011, Land cruiser P/U – 76 Wagon).

Early SRS-equipped (supplementary restraint system) systems used accelerometers built into the airbag control module consisting of a conductive mass suspended in a tube.  In a severe enough impact, the decelerating forces would break the tether restraining the mass and allow it to slide to the end of the tube, where it would electronically complete the circuit responsible for the deployment of the airbags.

Airbag technology improved over the last few years and external sensors are now being placed in the front of the vehicle (on both sides of the radiator on the new Toyota Hilux and Landcruiser utes).  These more improved sensors are still accelerometers, but they now detect impact many milli seconds before the occupant cell becomes distorted.

ONCA Strength When It Matters

ONCA has built up a good reputation as a manufacturer of quality and durable 4×4 accessories, investing significant resouces into designs that ensure quality is a priority in their products.

ONCA have been fitting front replacement bull bars on airbag equipped vehicles since 2003 and  has never been informed or heard of an incident where an airbag malfunctioned or did not deploy due  to an ONCA front  replacement bull bar being fitted to a vehicle or from being a sub standard product.

Below are some before and after images of ONCA customer’s vehicles that were involved in serious road accidents with vehicles fitted with ONCA front replacements bull bars, but managed to walk away from the accidents without any or serious injury.  ONCA have had very positive feedback from these customers who thanked us for the solid quality design of the ONCA front replacement bull bar, which took most of the impact during these mentioned collisions.

Airbag Deployment

Another question is whether the airbags will deploy unnecessarily due to low impact if the vehicle is equipped with an ONCA front replacement bull bar.  

ONCA have had several customer’s vehicles fitted with ONCA front replacement bull bars which were involved in various low impact collisions and the airbags thankfully did not deploy.  This is a very good indication that the ONCA  front replacement bull bar does not have an effect on the normal operation of the airbag triggering system of these vehicles.

We must all be realistic when it comes to vehicle airbag deployment, whether you have a standard vehicle or one fitted with accessories.  When searching the internet about airbag malfunctions then it is interesting to see the amount of airbag malfunctions in standard passenger vehicles without any accessories fitted.

Airbag compatibility has always been an important issue for ONCA as a company and always will be.
