moving anywhere in the bus and out the exit door, a vertical assist shall be provided either as the vertical<br />

portion of seat back assist (see Section 5.4.5.1.3) or as a separate item so that a 5th-percentile female<br />

passenger may easily move from one assist to another using one hand and the other without losing<br />

support. Excluding those mounted on the seats and doors, the assists shall have a cross-sectional<br />

diameterbe between 1-1/4 and 1-1/2 inches in diameter or width or shall provide an equivalent gripping<br />

no less than 1-1/2 inches of knuckle clearance around the assist, except the assists mounted on the door<br />

intrusion shall not produce sharp edges, loose rails, or other potentially dangerous conditions associated<br />

with a lack of structural integrity of the assist. Any joints in the assist structure shall be underneath<br />

supporting brackets and securely clamped to prevent passengers from moving or twisting the assists (see<br />

Section 5.4.6.1.1 regarding bright surfaces and glare). All areas of the passenger assists that are handled<br />

by passengers including functional <strong>com</strong>ponents used as passenger assists shall be of anodized aluminum<br />

or stainless steel. Connecting tees and angles may be powder coated metal castings. Assists shall<br />

withstand a force of 300 pounds applied over a 12-inch lineal dimension in any direction normal to the<br />

assist without permanent visible deformation. Brackets, clamps, screw heads, and other fasteners used<br />

on the passenger assists shall be flush with the surface and free of rough edges.<br />

tread and shall be easily grasped by a 5th-percentile female boarding from street level. Door assists shall<br />

be functionally continuous with the horizontal front passenger assist and the vertical assist on the front<br />
