Internal Staves
Contouring
With a little patience, you can easily bend the two Internal Staves to the
contour of the back as illustrated in the above diagram and detailed below.
-
First, remove the Internal Staves from the backpack.
-
Hold the Internal Stave vertically against the
back, at the position the Internal Stave will be at when inserted into the
backpack, on either side of the spine.
-
Ensure that the Internal Staves, and therefore
the backpack, do not protrude past the body by commencing at a point level
to where the sacrum and coccyx meet. It is important to note that the average
lower length of Internal Stave below the hipbone or Iliac Crest is 12.5cm.
This lower length of frame before the first curve would then be between 11cm
to 14cm depending on the Torso Length of the individual being fitted. All
White Mountain™ backpacks are by design, 12.5cm from the base of the Internal
Stave to where the Hip Belt crosses the hipbone or Iliac Crest. With a White
Mountain™ backpack, the easiest way to know where to begin bending is to mark
the Internal Stave at 12.5cm, then position this mark in the deepest part
of the back at the Lumbar Vertebrae level with the hipbone, or Iliac Crest.
-
Then contour the Internal Stave following the
curve of the back up to the finishing point, preferably at the top or no more
than 5cm above the shoulder.
-
If contouring the Internal Stave more than 5cm
past shoulder height, you must bend the extra length away from the neck at
approximately a 30º angle from the vertical to allow for head movement. We
do not recommend fitting an Internal Stave length longer than the individual
back. However, if it is necessary limit this extension to 5cm, although the
maximum extended height can be 10cm.
-
Check that the individual back you are fitting is symmetrical, as you may
need to bend each Stave a little differently. Generally, the individual back
will be symmetrical and you can bend the second Internal Stave to the match
the first Internal Stave you have contoured.
