2. Avoid cutting the ABS shell back to far especially at the transition zone between the
seat and back.
3. When you wish to create a notch for a lap belt, create the notch in the liners, not the
ABS shell (fig.10 ).
4. Trim the ABS shell with a jigsaw using a large toothed blade. Always use caution and
the appropriate protective equipment when using power tools (fig. 8).
5. Smooth the edges using wet-dry sandpaper or a deburring tool (fig. 9).
7.3.3 Modify the liners
The liners may be modified at the final fitting of the seating system or returned to the suppli-
er for finishing after a trial fit.
1.
Mark liners for trimming using a highly visible marker/pen.
2. For belt notches, notch the liner so the strap will lie across the body and in front of the
pelvis. As shown in fig. 5, the angle of the belt should be 60°-90°.
3. The liners should extend ½ in. longer than the edge of the ABS shell except at the posi-
tion of the belt notches (fig.10A).
4. Use caution when cutting the liners (fig. 11). A utility knife or very sharp scissors are
recommended.
7.3.4 Marking strap, buckle and belt position
The strap, buckle and belt positions are finished at the supplier.
1.
Clearly mark buckle and belt position on the ABS shell using a highly visible marker.
a. The belt connection point must be at least 2 in. from the edge of the shell.
This is to maintain structural strength at the seat: back transition.
2. Clearly mark the liner adjacent to the buckles to indicate strap position (fig. 12A).
a. The position should be selected to avoid interference with the user especially
at the arms.
b. 8 straps are recommended to securely hold the liners in place. This can vary
with the size of the seat.
3. The straps will be sewn directly to the liners. The buckles are riveted to the ABS shell
(fig. 13).
4. At the belt attachment position, a T-Nut will be inserted (fig. 12B).
8. Legal Information
All legal conditions are subject to the respective national laws of the country of use and may
vary accordingly.
