The hip belt must rest tight against the body
over the hip bone. It must be fastened so that,
after closing, it runs at an angle of 30° to 75°
from the horizontal when viewed from the side.
A steeper angle is desirable (closer to 75°), but
no higher under any circumstances. The belt
must not be twisted and not run over the per-
son's stomach.
The diagonal shoulder belt must run centrally
over the collarbone (at an angle of max. 55°
from the horizontal), must be a sufficient dis-
tance away from the neck and must lie tightly
against the body.
The belts should lie as firmly as possible
against the body without limiting the user's
comfort. They may not be kept away from the
body by parts of the wheelchair (armrests, side
sections, clothing guard, etc.).
Recommendation:
The diagonal shoulder belt should be connect-
ed directly to the latch plate of the transport
restraint system lap belt, not to the latch plate
provided in the vehicle.

belt with the respective connecting points (view from
the front)
Adjustable-inclination backrests must be set to
the most vertical position in order to ensure
upright sitting.
The height and distance of the headrest to the
head must be set so that the centre of gravity
of the upright head is in the middle of the head-
rest and the distance between the head and
headrest padding must be kept as little as pos-
sible (max. 2-3 cm).

height and distance from the head
To ensure that the wheelchair user is ade-
quately protected against collisions with vehi-
cle parts and panels, the following clearances
must be adhered to around him:
To the front, at least 65 cm (95 cm for use
of a lap belt without a diagonal shoulder
belt) measured from the front edge of the
head
To the rear, at least 45 cm measured from
the rear edge of the head
Upwards, at least 120 cm for a small, fe-
male adult, or at least 155 cm for a large,
male adult, each measured from the vehi-
cle floor.
