7 Use
7.1 Further instructions for use
• Attaching loads (e.g.backpacks) can adversely affect stability. Therefore, suspending additional loads on the
wheelchair is not permitted.
• The recommended overall width for manual wheelchairs in an operational state is 700mm. This specification
should ensure unhindered use of escape routes,for example. Please note that the product dimensions can
exceed the recommended value in versions with very large seat widths (for more information see see Page39
ff.).
• The wheelchairs in this series fully satisfy the minimum technical requirements for wheelchairs transportable by
train. However, please note that it is possible that not every individual wheelchair will fulfil the minimum require
ments due to the variation in designs (please see see Page40 for further details).
7.2 Getting in and transferring
CAUTION
Incorrect handling when getting in
Risk of falling, tipping or rolling away due to incorrect handling
►Activate the wheel lock each time before you get into or out of or transfer to or from the wheelchair.
►Always get into the wheelchair from the side, where possible.
►Never step on the foot plates when getting in and out.
►Do not support yourself on the wheel lock when getting in/out.
Users can choose the method for getting into and out of the wheelchair which is most suitable for them. The
respective procedure should be discussed and practised with a therapist.
As a rule, the frame tubes, seat bottom or side panels can be used as supports for getting into the wheelchair.
If getting in independently is not possible, transferring or getting in always has to be performed with the help of an
assistant. The manufacturer also offers transfer aids for getting in, such as transfer boards.
7.3 Legrests
CAUTION
Improper use of the legrests
Tipping over, falling due to errors in handling the product
►Fold up the footplates before getting in.
The leg supports support the user's feet.
The height of the leg support has been adjusted by qualified personnel to the length of the user's lower legs.
The angle of the foot support has been set by the qualified personnel so that it allows the ankles to rest in a com
fortable position.
Different leg support types and other accessories may be installed depending on the order:
Single-panel, angle-adjustable leg support (see fig.6)
The depth of the foot supports is either 125mm or 160mm.
14
Use
Avantgarde Teen2 T
Avantgarde Teen2 VR

Segmented, angle-adjustable leg support (see fig.7)
The depth of the foot supports is 160mm.
6 7
Leg support for short lower leg lengths (see fig.8)
This leg support enables positioning of the feet with lower leg lengths of 160 to 310mm.
Locking device for single-panel foot plate (see fig.9)
The locking device prevents inadvertent loosening of the foot plate, especially for users with spasticity. This option
cannot be combined with a leg support for short lower leg lengths.
8 9
Lateral heel blocks for the foot plate (see fig.10)
Lateral heel blocks prevent the feet from slipping off the leg supports. They can be combined with all segmented
and single-panel foot plates with a depth of 160mm.
Heel strap (not illustrated)

7.4 Seat and back upholstery
WARNING
Seat cushions and back support pads may ignite
Burns due to user error
►The seat and back support upholstery as well as seat cushions, padding and covers fulfil the normative
requirements for flame resistance. However, they may still ignite if fire is handled improperly or negligently.
►Keep away from all ignition sources, especially lit cigarettes.
CAUTION
Wear of the seat and back upholstery
Loss of functionality due to prohibited continued use
►Have the seat and back upholstery replaced immediately in case of damage.
The product is equipped with seat and back upholstery. Hook-and-loop fasteners on the seat upholstery are used
