6.16.2 Retrofitting with power seat tilt (optional)

The B400 power wheelchair can be retrofitted with two seat tilt versions.

The seat tilt option is delivered as a preassembled unit (fig. 61-1).
Preparation:

❒ Remove the fuse (see section 6.2).
❒ Remove the footrest (see section 6.6.1).
❒ Remove the seat frame (see section 6.10.3).
❒ Remove the backrest (see section 6.10.8).
❒ Remove the seat brackets.

2. Mount the rear seat brackets using the distance bushings (fig. 61-3).
3. Mount the bearing plate to the tilt frame to accommodate the patient's seat depth (fig. 61-4).

5. If required, replace the controller/control panel with the version designed for additional power
functions (see section 6.4/6.8).
