SECTION 11—TRANSPORT READY PACKAGE (TRRO)
Part No 1143190 71 TDX™ SP
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.
Steeper belt angles also reduce the tendency for upper-torso belts to pull the pelvic
belt onto the abdomen during frontal impact loading.
