1.1 Intent The human powered vehicle category is intended as an experiment in personal mobility. The objective is to build an efficient and stable machine powered entirely by human effort. NOTE: The RACV scrutineers have the final authority to decide if any vehicle or team competes in the event, based on safety and their interpretation of the following rules. 1.2 Seating Capacity, Wheels The vehicle shall carry a rider alone, and shall have three or more load bearing wheels arranged in a stable configuration. 1.3 Riding Position Riding position shall not compromise machine controllability or safety, nor shall the riding position place the rider in a potentially hazardous position in the event of a collision. For these reasons a prone riding position is not allowed. Note: A design which places the rider in an extreme or other than conventional reclined seating position shall be submitted to event organisers to gauge compliance with this clause. 1.4 Power Source Motive power shall be entirely supplied by the rider. 2.1 Inherent Safety The design shall provide protection for the rider in the event of a collision or rollover. (Refer Bodywork 2.3 and Occupant protection 4.0). The design must be free of protrusions or other features capable of causing interference or injury to fellow competitors or spectators. Vehicle control and stability shall not be jeopardised by inappropriate design and construction methods. For example: tilt steering or flexible steering columns are prohibited and a clearance of at least 30 cm is required between the rider’s chin and the steering wheel. 2.2 Exclusions Choice of design and construction materials is free, except that: The use of bicycle components shall be restricted to centre brackets, head stems and wheel dropouts with minimal use of adjacent original frame tubing. 2.3 Bodywork Fully or partially enclosed bodywork is encouraged. In any case the bodywork design and structure will be regarded as supplementary in terms of rider protection and is not a substitute for compliance with the roll bars and side intrusion protection requirements (see section 4.1.1) Where enclosed bodywork is fitted: • The rider shall be able to open and/or remove bodywork and exit the vehicle without external assistance in less than 6-seconds. • Bodywork shall be capable of being opened and or removed from outside the vehicle independently of the rider in an emergency. Rider and vehicle safety shall not be impaired by restricted ventilation or visibility, and provision for rain and fogging must be demonstrated. • Rider vision must not be impaired by excessively enclosed and restricting bodywork. Riders seated in the normal riding position are required to pass the following vision tests as depicted in the line drawings. 1. Sight an object on the road 5 metres in front of the vehicle.
2. Sight 180 degrees ahead of the rider, and other vehicles 15.0 degrees behind the rider on each side of the vehicle by turning their head. The intent of this clause is that a rider is able to turn their head to visually check for other vehicles before changing their position on the road.
4.1 Rollover Protection Two roll bars shall be fitted, a “head bar” and a “leg bar”. Both roll bars and the side intrusion protection must comply with the construction requirements outlined in section 4.2. Fully enclosed bodywork alone does not fulfill this requirement and therefore some vehicles may require a roll bar external to the bodywork. This roll bar must comply with all construction specifications. The underlying requirement of this rule is to have a sufficiently strong frame structure to support the weight of vehicle and rider in a rollover at speed. (A 40km/h impact is equivalent to dropping the vehicle on its roof from a first floor landing)
4.1.1 Construction Both roll bars and side intrusion bars shall be integral with vehicle frame, be of substantial structure and strength to support vehicle and rider in a roll over and side collision situation and comply with the dimensions listed. The main ‘head’ roll bar shall be longitudinally braced from its highest point to a major structural member (to form a tripod). 4.1.2 Dimensions With any of the competing riders in the normal riding position, the head roll bar must be fully visible outside the rider silhouette when viewed from the front or rear, and conform to the following dimensions. • Height above helmet -150 mm minimum • Width at top of helmet -150 mm minimum either side of the helmet • Width at shoulder level - 50 mm minimum either side of the shoulders • Forward or rearward - no more than 150 mm of the rider’s helmet • Roll bar shall envelope the rider when viewed from either front or rear. § The forward ‘leg’ roll bar must protect the rider’s legs, knees and feet from being crushed when the car is upside down. Note: A straight line from the top of one roll bar to the top of the other must have at least 50 mm clearance above the riders head. 4.1.3 Side Protection The vehicle design must provide side intrusion protection for the rider, either in the form of intrusion bars or structural framework that is as specified in section 4.1.1. Side intrusion must protect the rider from direct contact with another vehicle, with no part of the rider allowed to protrude outside the side protection in normal operation of the vehicle. The side protection must be designed to have a minimum 50 mm clearance around the rider and shield the area between the rider’s hip and shoulder from contact with another vehicle. Designs that do not prevent the wheel of another vehicle contacting the rider in a T-bone type collision will not be accepted.
4.2 Seat Belt 4.2.1 Type The vehicle must be fitted with an Approved and Certified adult FOUR point seat belt for all riders. Seat belts must have certification attached. Suggested suppliers: HEMCO INDUSTRIES Vic. Phone 03 5334 1213 Fax 03 5334 1011. Klippan, Type "Street Racer" 4 point, 2 inch webbing available through Repco stores. The seat belt will be completely standard, including buckle, stitching and mounting plates and must be adjustable (required to be demonstrated) for each individual rider. 4.2.2 Mounting The seat belt must be mounted to a major, non-moving, structural member of the vehicle or can be mounted to the seat provided it is suitably secured. Upper belts mounted behind the rider’s shoulders are required to be no more than 40 degrees from horizontal. 4.2.3 Positioning The positioning of buckles and belts on the rider’s body shall conform strictly to the belt wearing requirements of Australian Design Rules (ADRs) for motor vehicles. The relevant section of the ADR 4/01 is reproduced below. 'Seat belts are designed to bear upon the bony structure of the body, and should be worn across the chest, shoulders and low across the front of the pelvis; wearing the lap section of the belt across the abdominal area should be avoided. Seat belts should be adjusted as firmly as possible, consistent with comfort, to provide the protection for which they have been designed. A slack belt will greatly reduce the protection afforded to the wearer'. 4.3 Shielding 4.3.1 Rider Protection All moving components (wheels, chains, sprockets, gear wheels and controls) shall be fully shielded to prevent accidental hazardous contact with rider or clothing. 4.3.2 Protection of other Vehicles Chains, gear wheels and sprockets shall be suitably shielded to prevent their contact with other vehicles. 4.3.3 Shielding from Road Surface Vehicles must be fitted with an under-tray or floor panel which prevents the rider’s feet from contacting the ground when seated in the riding position. Pedal toe clips, elastic straps or pedal-to-shoe locking devices do not fulfill the requirements of this clause. 5.1 Type The type of steering mechanism is free, provided the driver is afforded continuous positive control without the need for regular adjustment. Tilt steering or flexible steering columns are prohibited, and a clearance of at least 30 cm is required between the rider’s chin and the steering wheel. 5.2 Freedom from Binding and Fouling Steering linkages shall operate freely from full left to full right lock without binding or fouling. 5.3 Lock Stops Independent positive stops shall be provided to limit the steering linkage movement at maximum lock. This is to prevent over centre travel, or contact between steering components, tyres or wheels, or against occupants, seats or frame components. (100 mm minimum clearance is required between the occupant and any rotating part). 6.1 Independent Systems The vehicle shall be fitted with a minimum of two effective independent braking systems. All wheels in contact with the road must have a braking capability. 6.2 Directional Stability Brakes on the same axle line (e.g. both front wheels) must operate via a single lever, so that independent operation of any braking system shall not have the potential to affect directional stability of the vehicle. That is, the braking power of each and every braking system shall be symmetrical about the vehicles longitudinal centre line. 6.3 Simultaneous Operation The two braking systems shall be able to be operated by the rider simultaneously. 6.4 Steering Control Full steering control shall be maintained while braking systems are being operated. 7.1 Lighting The vehicle shall be fitted with the following as a minimum requirement.
7.1.2 Tail Light At least one red tail light, securely mounted on the vehicle, with a minimum lens area of 7 cm2. Red flashing LED-type tail lights are acceptable. 7.1.3 Outline Lighting The use of reflective material or strip lighting to indicate machine width and height (especially from the rear) is encouraged. 7.1.4 Mounting All lights are required to be securely mounted for the duration of the event to maintain correct aim. 7.1.5 Batteries Wet cell batteries must be housed in a sealed box (e.g. plastic) that will prevent spillage if the battery is inverted or damaged. 7.2 Mirrors 7.2.1 Number and Type The vehicle shall be fitted with two flat plain or mildly convex mirrors, one on either side of the rider. 7.2.2 Positioning Each mirror shall be positioned no lower than rider chest height and such that: • The rider is afforded a clear view to the rear. • The smallest rider must be able to reach and adjust each mirror from the normal riding position. 7.2.3 Size Reflecting surface area of each mirror shall be 40 cm² minimum. 7.2.4 Mounting Mirrors shall be rigidly mounted to non-moving chassis or body members and be free from vibration. 7.3 Warning Device An electric audible warning device shall be fitted (e.g. smoke alarm siren) and operate from the normal riding position. The device must not run continuously and operate via a momentary switch. The horn must emit sound in excess of 85 dbA measured directly in front of the vehicle at a distance of 1 metre. This will be checked at scrutineering. 7.4 Other Devices Any other equipment, e.g. drink bottle, shall be securely mounted and shall not impair rider control in its mounting or use. 7.5 Speedometer All vehicles shall be equipped with a simple electronic speedometer (e.g. Cat-eye) to monitor speed during the event (pit area speed limit of 15 kph). 8.1 School Name Each vehicle shall have their school name visibly displayed on either side of their vehicle. 8.2 Identification Panels Each vehicle shall have three white identification panels. One of each of these panels should be visible from the front and either side. Identification panels shall be either 250 mm by 300 mm or a circle 300 mm diameter.
