What Guidelines We Use To Build Our Barwork
For many years, Vehicle Frontal Protection Systems (VFPS), i.e. bullbars and roobars, have been accepted as an accessory for most types of vehicles, including passenger cars, four-wheel drives, SUV’s, forward control vehicles, etc. However, the continued development of vehicle technology and ongoing improvements in vehicle design and safety systems have led to a situation whereby a VFPS may interfere with the sophisticated safety system designed into modern vehicles. Lets look at some of the points that get raised with us quite often.
Some of the main concerns that we need to consider are;
- Incompatibility with Vehicle airbags
- Nullification of Crumple Zones
- Incompatibility with other vehicles
- Danger to pedestrians
After being fitted with the VFPS, the vehicle must continue to comply with any applicable Australian Design Rules (ADRs), Australian Standard or any relevant State road worthiness regulations.
These may include:
- Occupant crash protection regulations (airbags). Vehicles built after certain dates are required to comply with frontal and/or side crash protection standards. Fitting a VFPS may have an effect on the crash performance/airbag deployment. While VFPS manufacturers are not required to conduct full-scale crash tests of their products, some do.
- A crumple zone is intended to slow down the effects of a crash on you and your passengers. Crumple zones absorb energy and help to reduce the speed of the car occupants in relationship to the car itself. A correctly designed and manufactured VFPS do not effect crumple zones.
- Sharp edges and protrusions are a danger to other vehicles and/or pedestrians. Each VFPS needs to generally conform to the shape, in plan view, front and side view of the front of the vehicle to which it is fitted. VicRoads specifies what types of edges on VFPS are allowed, while these are similar to what appears in the Australian Standard, individual State roadworthy regulations must be adhered to.
Design and profile
The shape and dimensions of a bull-bar strongly influence the degree of protection offered to other road users.
- The bull-bar shall follow the profile of the vehicle to which it is fitted.
- Fitting the bull-bar must not increase the width of the vehicle (excluding the mirrors).
- Any sharp edges on the bull-bar shall be chamfered or radius
- No open-ended frame members are allowed on the outer
- No small components (such as brackets) shall be attached to the front of the bull-bar.
