Graham
is a product of a joint work of a sculptor, a trauma surgeon, and a
road safety engineer, who designed him as a part of a new Australian
road safety campaign. The three worked together to create a projection
of the kind of body that humans would need to have in order to withstand
a car crash. This is what they have come up with.
Meet Graham. He might look different but I assure you that he’s human!
1.The reason he looks the way he does is because his body has been modified to withstand a car crash.
2.Graham was created as part of a new Australian road safety campaign
3.He was designed by sculptor Patricia Piccinini, a leading trauma surgeon, and a road safety engineer.
4.He has multiple nipples to protect his ribs like a natural set of airbags
5.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
6.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
7.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
8.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
9.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
10.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.
11.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
12.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.
13.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.
