6 TRANSPORT READY OPTION (TRRO) Seating System ƽ WARNING This wheelchair has been tested for seating in a motor vehicle with the factory installed seating system only. When feasible, wheelchair occupants should transfer into the vehicle seat and use the OEM (Original Equipment Manufacturer) vehicle-installed restraint system Ensure that the factory installed seating system is secured to the wheelchair frame before operation. Refer to the seating system owner's manual. 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. Preferred Zone Optional Zone Side View 45° 30° 75°  For this procedure, refer to FIGURE 4 on page 73. Invacare® TDX®SP, TDX SR 72 Part No 1143190
