More On Invacare Matrx PB Back

Installing Matrx PB Back:

  • Verify that the overall fit and alignment of the back is correct (make adjustments as needed).
  • Fully secure the cane clamp screws onto both back posts, and tighten the set screws to ensure the mounting plates do not slip or rotate.
  • To best determine the optimal depth and recline settings for the back, the user should be seated in the wheelchair. While seated, loosen the depth/recline screws on the mounting plates and adjust the back to the desired depth and recline angle. Re-tighten all screws to lock the back in position.
  • Ensure that the depth/recline adjustment for the back is made symmetrically on the left and right mounting plates. Use score lines to make symmetrical adjustments.
  • The vertical score lines on the mounting plates are designed as a point of reference to assist with symmetrical mounting. Since the back can be mounted in a rotated (reclined) position if desired, it will not always be mounted parallel with these vertical lines.
