Replacing/Retrofitting The Seat Plate - Otto Bock discovery tmax Service Manual

Testing the Locking Mechanism
CAUTION
Incorrect setting of the locking mechanism linkage
Falling from the seating shell due to malfunction, damage to/destruction of the release mechanism
► Adjust the length of the locking mechanism linkage so that the locking pins fully engage in the locking plate in
the seat frame and the locking mechanism is in the front position. Only then is the support of the seat assured
with extreme settings or when driving over rough surfaces.
► Secure the screw connections of the locking mechanism linkage so it is free of tension, without pulling or
pushing.
Carry out a functional test after assembly is complete. Note the following:
• The locking pins must fully engage in the locking plate in all positions. Reference point: the locking pins pro­
trude slightly from the locking plate (see Fig. 50, item 1).
• It must be possible to depress the locking pedal to the stop without a lot of force. The mechanism unlocks
completely in this process. Reference point: the locking pins are recessed 1 – 2 mm in the plastic locking
mechanism housing.

3.7.5 Replacing/Retrofitting the Seat Plate

1) For replacement: Loosen all mounting screws (countersunk head screws) between the seat plate and seat
plate supports (see Fig. 51, item 1).
2) For retrofitting: Prior to installation, slightly loosen 2 x Allen head screws on the back plate (see Fig. 11,
item 1) and turn the cross tube by 90°. Remove the Allen head screws from the cross tube (see Fig. 5, item 2).
3) Position the seat plate:
→ The front of the seat plate is flush with the front of the lateral tubes of the seat frame (see Fig. 51, item 2).
→ The seat plate is centred between the lateral tubes of the seat frame.
→ Install additional seat plate supports if required (see next section).
4) Connect the seat plate and rear cross tube with 4 countersunk head screws (see Fig. 5, item 2).
5) Connect the seat plate and front cross tube with 2 countersunk head screws.
6) Tighten all countersunk head screws to a torque of 10 Nm.
