Meet Graham. He might look a little
different but I assure you that he’s human. Well, sort of. The reason he
looks the way he does is because his body has been modified to
withstand a car crash.
Graham was created as part of a new
Australian road safety campaign by the Transport Accident Commission
(TAC). He was designed by sculptor Patricia Piccinini, a leading trauma
surgeon, and a road safety engineer, who modified him based on their own
knowledge of traffic accidents.
The result isn’t a pretty sight but
it’s certainly a sobering one. As you can see, Graham doesn’t have a
neck because these snap easily in car accidents. He also has a flat,
fleshy face to protect his ears and nose. And if you’re wondering about
all those extra nipples, they’re to protect his ribs like a natural set
of airbags.
Don’t have a body like Graham’s? Then think about slowing down next time you’re behind the wheel.

Graham’s brain is the same as yours, but his skull is bigger with more fluid and more ligaments to support the brain when a collision occurs
The brain is one of the most vulnerable parts of our body. It sits
delicately surrounded by cerebrospinal fluid, which acts as an inbuilt
safety mechanism to protect the brain from day-to-day knocks and jolts.
Graham has a rather flat face and a lot of fatty tissue to absorb the energy of an impact
Our faces are a delicate mix of bone, muscle and cartilage. Many
people injured in car accidents receive fractures to their nose,
damaging not only the bone but disrupting sinuses and the delicate parts
behind the cheekbone. To combat this, Graham has a rather flat face.
His nose is reduced and his ears are protected by the larger structure
of his skull and neck
Graham has been designed with airbag-like ribs with sacks that do a similar job to that of an airbag
Car seat belts are designed to use the strength of the ribs to help
us withstand the forces of a crash. That’s why the three-point seatbelt
rests across your ribs and sternum and across your pelvis. It loads the
centre of your chest, spreading the force over the ribcage until the
ribs break when the force becomes too great.
Graham’s skull is a lot bigger, it’s almost helmet like and it’s got these inbuilt crumple zones that would absorb the energy on impact
The skull absorbs a lot of force on impact simply by
fracturing. Essentially this stops the force from carrying through to
the brain in much the same way a helmet works. Graham’s skull has been
engineered to absorb more of the impact earlier, much like a helmet.
Graham’s knees have movement in all directions so they are less likely to be injured
When a pedestrian is hit by a car it’s
usually when they’re stepping out from a curb. On impact, the immediate
problem is that the knee is only built to bend in one direction, so it
will almost always break first. Depending on the force of the impact,
the tendons can also pull, twist and hyperextend well beyond their
intended radius.
Graham’s neck is fortified with a brace-like structure that protects his head from injury when there is a sudden movement
There is not enough strength in the neck
to stop the head from jolting forward in a crash. The forward motion
causes a hyperflexion injury and the backwards motion a hyperextension
injury. Simply put, the neck is placed under more pressure than its
structure can manage. The added danger is the spinal cord running
through the neck. If it is to bend and stretch too much it will break,
causing serious injuries like paraplegia or quadriplegia.
Graham has thicker and tougher skin to shield and reduce abrasions and road rash
A pedestrian impact is mostly blunt force trauma. However, if our
bodies are pitched to the road or if broken glass is involved, then cuts
and abrasions can occur. Skin is vulnerable to the road, with bitumen
potentially wearing through clothing. This is even more important for
motorcyclists and cyclists, who only have minimal protection between
themselves and the road.
Strong, hoof-like legs with added joints allow him to jump out of the way quickly in a “spring-loaded” fashion
For pedestrian crashes, there are now so
many variables that affect injury severity – the size of the vehicle,
height, speed and angle of impact. And there are many situations where
legs are badly damaged. In fact, injuries to the legs, feet and ankles
can cause long-term debilitation because we are so reliant on them for
everyday movement. The shin itself is the least protected bone in the
body, with only a thin layer of skin covering it.
