Replacement of collapse protec-
tion attenuators
A collapse protection attenuator is mounted in
parallel with the actuator for stand function. If the
actuator breaks down with the seat in the standing
position, then the collapse protection attenuator
ensures that the seat will safely and slowly return
down to the sitting position.
Removal
1. With the seat in the sitting position, run the
seat lift up in order to access it more easily
from below.
2. Remove the collapse protection attenuator by
loosening its two retaining screws, see Fig. 83.
Fitting
Mounting is performed in the reverse order.
Replacement of parallel struts
Depending upon the model of the seat, the
number of parallel struts can vary. All parallel
struts are however mounted in the same manner,
using two screws, see Fig. 84.
1. With the seat in the sitting position, run the
seat lift up in order to access it more easily
from below.
2. Remove the parallel strut by loosening its two
retaining screws.
Fitting
1. When replacing a parallel strut for an arm rest
or back rest, check that the marking is in
accordance with the other settings, see
”Setting the seat depth” on pages 7-13.
2. Mount the parallel strut using its two retaining
screws.
Fig. 84. The parallel strut is mounted with two
screws, the parallel strut for the back/legs
is shown in the picture.
Always observe extreme caution when removing a
parallel strut since it can involve heavy parts of the
seat becoming unstable and needing support in
another manner.
