KNEE POSITION

Pads to protect rider's joints
This time I will focus on the knees.
The most common injuries sustained during accidents are
This is an injury to the patella and the posterior cruciate ligament in the knee joint.
The patella was originally an ossified muscle-tendon of the quadriceps femoris (a muscle attached to the front of the thigh).
When moving the knee, it becomes the fulcrum of the lever and plays a very important role in the movement of the knee.
The posterior cruciate ligament is located within the knee joint and is an important ligament that prevents the lower leg bone from sliding backwards in relation to the femur.
The friction coefficient of biological joints is 0.005 to 0.02.
Artificial joint is 0.1-0.5,
ice and ice is 0.03
You can see how excellent biological joints are.
Just because it comes with a pad doesn't mean it's safe,
How about wearing padded leather pants to protect your precious knees?
I put on my pants, bent my knees and checked the position of the knee pads.
There are many cases where the position of the pad is slightly misaligned when riding the bike.
The key point in adjusting the knee position of the pants is the inner thigh line.

For the line connecting the femoral head to the tibia (Mikulicz Line),
The inclination of the femoral shaft is said to be approximately 175° to 165°.
The alignment of the femur is in an inverted V-shape with respect to the axis of the lower leg.
When standing upright and in a sitting position (sitting on a seat) with the hips wide
The length of the inner thigh line varies greatly.

In the case of women with a wide pelvis, this inverted C shape is stronger than in men,
There is a big difference in the length of the inner thigh line when the legs are open and when the legs are closed.

For those who are considering a leather coverall that matches their motorcycle and style.
We look forward to hearing from you.
