vertical metal structure beginning no more than 102 millimeters (4

inches) above the lowest point of the tires on the striking side of the

test vehicle when the vehicle is loaded as specified in S8.16 and

extending above the highest point of the roof of the test vehicle. The

pole is 254 mm <plus-minus>3 mm (10 inches) in diameter and set off from

practices set forth in SAE Recommended Practice J211, March 1995,

``Instrumentation for Impact Tests,'' Class 1000.

S8.28 Positioning procedure for the Part 572 Subpart M Test Dummy--

vehicle to pole test. The part 572, subpart M, test dummy shall be

initially positioned in the front outboard seating position on the

struck side of the vehicle in accordance with the provisions of S7 of

Standard 214, 49 CFR 571.214, and the vehicle seat shall be positioned

as specified in S6.3 and S6.4 of that standard. The position of the

dummy shall then be measured as follows. Locate the horizontal plane

passing through the dummy head center of gravity. Identify the rearmost

point on the dummy head in that plane. Construct a line in the plane

that contains the rearward point of the front door daylight opening and

is perpendicular to the longitudinal vehicle centerline. Measure the

longitudinal distance between the rearmost point on the dummy head and

this line. If this distance is less than 50 mm (2 inches) or the point

is not forward of the line, then the seat and/or dummy positions shall

be adjusted as follows. First, the seat back angle is adjusted, a

maximum of 5 degrees, until a 50 mm (2 inches) distance is achieved. If

this is not sufficient to produce the 50 mm (2 inches) distance, the

seat is moved forward until the 50 mm (2 inches) distance is achieved or

until the knees of the dummy contact the dashboard or knee bolster,

whichever comes first. If the required distance cannot be achieved

through movement of the seat, the seat back angle shall be adjusted even

further forward until the 50mm (2 inches) distance is obtained or

[[Page 449]]

until the seat back is in its full upright locking position.

S9. Orthogonal Reference System. The approach angles specified in

S8.13.4 are determined using the reference system specified in S9.1

through S9.4.

S9.1 An orthogonal reference system consisting of a longitudinal X

axis and a transverse Y axis in the same horizontal plane and a vertical

Z axis through the intersection of X and Y is used to define the

horizontal direction of approach of the headform. The X-Z plane is the

vertical longitudinal zero plane and is parallel to the longitudinal

centerline of the vehicle. The X-Y plane is the horizontal zero plane

parallel to the ground. The Y-Z plane is the vertical transverse zero

plane that is perpendicular to the X-Y and X-Z planes. The X coordinate

is negative forward of the Y-Z plane and positive to the rear. The Y

coordinate is negative to the left of the X-Z plane and positive to the

right. The Z coordinate is negative below the X-Y plane and positive

above it. (See Figure 1.)

S9.2 The origin of the reference system is the center of gravity of

the headform at the time immediately prior to launch for each test.

S9.3 The horizontal approach angle is the angle between the X axis

and the headform impact velocity vector projected onto the horizontal

zero plane, measured in the horizontal zero plane in the counter-

clockwise direction. A 0 degree horizontal vector and a 360 degree

horizontal vector point in the positive X direction; a 90 degree

horizontal vector points in the positive Y direction; a 180 degree

horizontal vector points in the negative X direction; and a 270

horizontal degree vector points in the negative Y direction. (See Figure

2.)

S9.4 The vertical approach angle is the angle between the

horizontal plane and the velocity vector, measured in the midsagittal

plane of the headform. A 0 degree vertical vector in Table I coincides

with the horizontal plane and a vertical vector of greater than 0

degrees in Table I makes a upward angle of the same number of degrees

with that plane.

the center of that target is moved to any location that is within a

sphere with a radius of 25 mm, centered on the center of the original

target, and that can be contacted by the forehead impact zone at one or

more combination of angles.

(c) If there is no point within the sphere specified in S10(b) which

the forehead impact zone of the free motion headform can contact at one

defining the nearest edge of the upper roof. Target SR3 is located at

the middle of the line between Point 15 and Point 16 in Plane 27,

measured along the vehicle interior surface.

(1) If Plane 27 intersects a door or daylight opening, the Point 15

is located at the intersection of Plane 27 and the upper edge of the

door opening or daylight opening.

(2) If Plane 27 does not intersect a door or daylight opening, the

Point 15 is located on the vehicle interior at the intersection of Plane

27 and the horizontal plane through the highest point of the door or

daylight opening nearest Plane 27. If the adjacent door(s) or daylight

opening(s) are equidistant to Plane 27, Point 15 is located on the

vehicle interior at the intersection of Plane 27 and either horizontal

plane

[[Page 452]]

through the highest point of each door or daylight opening.

(b) Except as provided in S10.7(c), if a grab handle is located on

the side rail, target SR3 is located at any point on the anchorage of

the grab-handle. Folding grab-handles are in their stowed position for

testing.

(c) If a seat belt anchorage is located on the side rail, target SR3

is located at any point on the anchorage.

S10.8 Rear header target (target RH). Locate the point (Point 17)

at the intersection of the surface of the upper vehicle interior, the

mid-sagittal plane (Plane 28) of the outboard rearmost dummy and the

plane, described in S8.15(h), defining the rear edge of the upper roof.

Locate the point (Point 18) as provided in S10.8(a) or S10.8(b), as

appropriate. Except as provided in S10.8(c), Target RH is located at the

mid-point of the line that is between Point 17 and Point 18 and is in

Plane 28, as measured along the surface of the vehicle interior.

(a) If Plane 28 intersects a rear door opening or daylight opening,

then Point 18 is located at the intersection of Plane 28 and the upper

edge of the door opening or the daylight opening (if no door opening).

(b) If Plane 28 does not intersect a rear door opening or daylight

opening, then Point 18 is located on the vehicle interior at the

intersection of Plane 28 and a horizontal plane through the highest

point of the door or daylight opening nearest to Plane 28. If the

adjacent door(s) or daylight opening(s) are equidistant to Plane 28,

Point 18 is located on the vehicle interior at the intersection of Plane

28 and either horizontal plane through the highest point of each door or

daylight opening.

(c) If Target RH is more than 112 mm from Point 18 on the line that

is between Point 17 and Point 18 and is in Plane 28, as measured along

the surface of the vehicle interior, then Target RH is the point on that

line which is 112 mm from Point 18.

S10.9 Upper roof target (target UR). Target UR is any point on the

upper roof.

S10.10 Sliding door track target (target SD). Locate the transverse

vertical plane (Plane 29) passing through the middle of the widest

opening of the sliding door, measured horizontally and parallel to the

vehicle longitudinal centerline. Locate the point (Point 19) at the

intersection of the surface of the upper vehicle interior, Plane 29 and

the plane, described in S8.15(h), defining the nearest edge of the upper

roof. Locate the point (Point 20) at the intersection of Plane 29 and

the upper edge of the sliding door opening. Target SD is located at the

middle of the line between Point 19 and Point 20 in Plane 29, measured

along the vehicle interior.
