of arms 20, 22 pivotally mounted on pins 32 to move between a
rest position (indicated in solid lines in Figure 2) to allow
the
driver to sit down, and a restraining position (shown in
phantom lines in Figure 2) to hold the driver in the seat.
The release
of the arms is described by Niebuhr in the paragraph spanning
pages 4 and 5 as follows:
Only when the driver arbitrarily releases the
pivoting arms 20, 22 can they be pivoted back into

to the locking means (not shown) via a linkage or a
tie cable.
