Section 442.270 Seating
a) No bus shall be equipped with "jump" or portable
seats (this does not include child restraint systems).
b) The driver's seat shall be rigidly positioned and have a
fore-and-aft adjustment without the use of tools or other nonattached devices.
c) A flip-up seat for passengers may be located only immediately
adjacent to any side emergency door. The flip-up seat must conform to the
following:
1) The seat must be designed so that, when in the folded
position, the seat cushion is flat against the seat back to prevent a child's
limb from becoming lodged between the seat cushion and seat back.
2) The seat must be designed to discourage a child from standing
on the seat cushion when in the folded position.
3) The working mechanism under the seat must be covered to
eliminate any tripping hazard.
4) All sharp metal edges on the seat must be padded to prevent
any snagging hazard.
5) No portion of the door latch mechanism can be obstructed by a
seat.
6) There must be at least 11.7 inches (30 cm) measured from the
