Seat Dump; Changing Seat-To-Floor Height; Rear Seat-To-Floor Height - Invacare Compass XE Owner's Operator And Maintenance Manual

Seat Dump

The rear seat‐to‐floor height measurement in combination with the front seat‐to‐floor
height measurement determine the amount of seat dump the wheelchair will have.
For Example:
NOTE: Invacare recommends that the rear seat‐to‐floor height be at least 3/8 inch shorter than the
front seat‐to‐floor height. Otherwise a forward seat dump can occur.

Changing Seat-to-Floor Height

Rear Seat-to-Floor Height

NEVER use the standard multi-position or offset multi-position axle plates with the
recliner option. Using the standard multi-position or offset multi-position axle
plates will reduce the stability of the wheelchair, causing injury to the user and/or
assistant(s).
NOTE: For this procedure, refer to FIGURE 13.3.
The following axle mounting positions for rear seat‐to‐floor height apply to any of the
axle mounting plates.
After determining axle mounting plate placement for necessary rear seat‐to‐floor height,
refer to Adjusting Rear Wheel Height on page 112 to reposition the axle mounting plates.
NOTE: The following rear seat‐to‐floor heights shown are the most common rear seat‐to‐floor
heights available.
