The 5 cm (2“) Aircraft Buckle
lap strap. (Fig. 4.10).
The 5 cm (2”) Aircraft Padded
Lap strap. (Fig. 4.11)
The lap strap fitted for a right-
handed user. (Fig. 4.12)
The lap strap fitted for a left-
handed user. (Fig. 4.13)
Place the strap loosely across the
seat with the opening end of the
buckle facing to the right for a
left-handed person and to the left
for a right-handed person. (Fig.
4.14)
Pass the other ends of the strap
through the gap between the
backrest posts and the backrest
upholstery as shown above. (Fig.
4.15)
Feed the bracket ends of the
straps under the backrest brace
bar as shown. Ensure that the
adjuster buckles can be accessed
and the strap is not twisted. (Fig.
4.16)
Pass the bolt through the plain
washer and strap bracket. (Fig.
4.17)
Place a saddle washer on the bolt
(Fig. 4.18).
Pass the bolt through the seat
frame. Mount as shown above
for the 36-46cm, (14”-18”), seat
depth. Mount the bolt the other
way round, with the head on the
inside, for seat depths greater
than 51cm, (20”), to avoid a
clash with the back post bracket
(Fig. 4.19)
Place the other saddle washer on
the end of the bolt and against
the frame. Fit the plain washer
and nut. Tighten using a 4.0mm
Allen key and 10.0mm spanner
(Fig. 4.20).
Adjust the lap strap to suit,
leaving no more than a hand’s
width gap for comfort and safety.
(Fig. 4.21).
The hand clearance should be
tight and not allow large gaps.
Generally, the lap strap should be fixed
so that the straps sit at an angle of
approximately 45° (Fig. 4.22), and when
correctly adjusted should not allow user
to slip down in the seat.
DANGER!
Always make sure that the lap strap is correctly secured and •
adjusted prior to use.
Too loose a strap could cause the user to slip down and •
cause serious injury.
Check lap strap and securing components at regular intervals •
for any signs of fray or damage. Replace if necessary
When servicing, check for correct operation of the release •
buckle and for any signs of wear on the material or plastic
brackets
NOTES:
1. Standard Sling - Lap strap movement is restricted by
upholstery
2. Contoured back - Use universal bottom bracket as per recline
