Instructions for the proper use of the vest:
1) Make sure that the user is sitting in the best possible position:
§in the middle of the seat,
§deeply in the seat in such a way that the user's lumbar spine rests against the backrest.
2) Secure the user's pelvis with, for example, a pelvic belt, thigh abduction belts or an
abduction block.
3) Make sure that the side supports of the device, if used, are set in the correct position. It is
required that the users with the poor trunk control use the side supports. The side supports
limit the lateral movements of the user's body, which could lead to the compression of the
vest straps on the neck of the user.
4) Secure the vest:
§fasten and adjust the lower straps of the vest, so that the lower edge of the vest is located
near the lower abdomen of the user,
§fasten the shoulder straps of the vest,
§fasten the horizontal strap of the vest (if present),
§make sure that you can insert a straightened hand between the vest and the user's body.
§make sure that the vest cannot move by itself towards the user's neck,
§check if the buckles of the vest do not open under pressure.
5) Check the user's position:
To prevent injuries and to minimize the risks associated with the use of the vest, the
following rules should be followed:
1) The position of the vest MUST be checked each time after putting the user in the seat.
2) Special attention should be paid to protecting the user from falling forward, slipping off
the seat or lifting the pelvis. The vest MUST be used with the accessories which will secure
the user's pelvis at all times (e.g. the pelvic belt, thigh abduction belts or the abduction
block). The use of the vest cannot be considered separately but as a part of a general
posture support system including supports such as pelvic belts, foot support, torso
stabilization, thigh abduction belts, tilt-in-space position and reclining backrest.
3) Special attention should be paid to ensuring that the entire foot of the user has stable
support. If the device is not equipped with a foot support, the user's feet must rest firmly
against the ground.
4) It should be remembered that any change of the inclination angle of the backrest, seat, foot
support or tilt-in-space function might affect the effectiveness of the belts and supports!
5) Special attention should be paid to the use of stabilization elements or sidesupports. If the
user has poor trunk control, the side supports will limit the lateral movements, which could
lead to the compression of the vest straps on the neck of the user.
