PROTEOR EASY RIDE 1P650 Notice D'utilisation page 11

Biking position:
Sagittal plane:
Mount the knee such that its axis is in line with the axis of the socket.
The load line must pass through the centre of the hip joint, the centre of the socket and
to the rear of the axis of rotation of the knee.
The load line passes through the posterior of the foot, 1/3rd of its length from the back
of the foot (depending on the alignment recommendations for the foot).
Frontal plane:
Mount the knee such that its axis is in line with the axis of the socket.
The load line passes through the centre of the knee and the centre of the foot.
An internal rotation of the leg segment may be necessary.
Note: These alignment recommendations draw on the results of laboratory tests and trials. When
the patient is practising a sport, these theoretical alignments can be modified so long as the
setup of the device complies with the rules regarding safety and the rules applicable to the
correct use of the device on the type of equipment used. The patient's safety and comfort
depend on them.
B. Change of position setting
To switch between the SLIDING (for sports performed on a board, skis, skates, etc.) and BIKING positions, move the pin that secures
the upper end of the shock absorber from position 1 to position 2, as follows:
•
Unscrew the two screws at the two ends of the pin using the two Torx T30 keys supplied.
•
Remove the pin using the pin removing tool supplied.
•
Insert the pin in the desired position.
•
Refit the two screws with their washers, apply a drop of XC048 low-strength thread-locking compound, and tighten the
screws to a torque of 6 Nm.
Extension
(Pre-flexion of 12°)

The screws must be tightened and untightened with a torque wrench fitted with a Torx T30 bit.
If the screw head becomes deformed, replace the screw with one of the two spares supplied.
The maximum flexion stops in the BIKING position are only present to protect the shock-absorber; they must not under any
circumstances be subjected to stresses regularly and repeatedly.
