SECTION 17-TRANSPORT READY PACKAGE Positioning Belts ƽ WARNING The angle of the pelvic belt should be within the preferred zone of 45 to 75 degrees to the horizontal OR within the optional zone of 30 to 45 degrees to the horizontal. Steeper side-view pelvic belt angles are especially important if the pelvic belt is intended to be used for postural support in addition to occupant restraint in a frontal crash. Steeper angles will reduce the tendency for a vertical gap to develop between the user and the belt due to compliance of seat cushions and belt movement, thereby reducing the tendency for the user to slip under the belt and for the belt to ride up on the soft abdomen during normal use. Side View Preferred Zone Optional Zone 45° 30° 70° Steeper belt angles also reduce the tendency for upper-torso belts to pull the pelvic belt onto the abdomen during frontal impact loading. NOTE: For this procedure, refer to FIGURE 17.4. 1. The pelvic belt should be worn low across the front of the pelvis. 2. Position the upper-torso belt(s) over the shoulders. 3. The belt(s) should not be held away from the body by wheelchair components or parts, including but not limited to wheelchair armrests or wheels. Refer to FIGURE 17.4 for proper and improper positioning of the belts. 4. Ensure the belt(s) are not twisted. 5. Adjust belts as firmly as possible, being mindful of user comfort. DO POSITION BELT INSIDE OF ARMRESTS, WHEELS, ETC. DO NOT POSITION BELT OUTSIDE OF ARMRESTS, WHEELS, ETC. FIGURE 17.4 Positioning Belts 3G Storm Series® Wheelchairs 128 Part No 1134791

WARNING
The angle of the pelvic belt should be
within the preferred zone of 45 to 75
degrees to the horizontal OR within the
optional zone of 30 to 45 degrees to the
horizontal.
Steeper side-view pelvic belt angles are
especially important if the pelvic belt is
intended to be used for postural support
in addition to occupant restraint in a
frontal crash. Steeper angles will reduce
the tendency for a vertical gap to
develop between the user and the belt
due to compliance of seat cushions and
belt movement, thereby reducing the
tendency for the user to slip under the
belt and for the belt to ride up on the
soft abdomen during normal use.
Steeper belt angles also reduce the tendency for upper-torso belts to pull the pelvic
belt onto the abdomen during frontal impact loading.
NOTE: For this procedure, refer to FIGURE 17.4.
1.
The pelvic belt should be worn low across the front of the pelvis.
2.
Position the upper-torso belt(s) over the shoulders.
3.
The belt(s) should not be held away from the body by wheelchair components or
parts, including but not limited to wheelchair armrests or wheels. Refer to
FIGURE 17.4 for proper and improper positioning of the belts.
4.
Ensure the belt(s) are not twisted.
5.
Adjust belts as firmly as possible, being mindful of user comfort.
