Vehicles manufactured by final stage manufacturers on or after September 1, shall, except as provided in S6.

Brace means a fixed diagonal structural member in an open body vehicle that is used to brace the roll-bar and that connects the roll-bar to the main body of the vehicle structure. If a target is on a seat belt anchorageregulatikn if the seat belt anchorage is adjustable, tests are conducted with the anchorage adjusted to a point midway between the two extreme adjustment positions.

All major automakers have different categories of dynamic testing methods as part of their design process in validating their designs against the FMVSS requirement. Target SR2 is located at the middle of the line between Point 13 and Point 14 in Plane 26, measured along the vehicle interior. Seat belt anchorage means any component involved in transferring seat belt loads to the vehicle structure, including, but not limited to, the attachment hardwarebut excluding webbing or straps, seat frames, seat pedestals, and the vehicle structure itself, whose failure causes separation of the belt from the vehicle structure.

A commercially available CAE process automation tool was used to automate these steps and generate a head impact simulation model. The section you are viewing is cited by the following CFR sections. Locate a horizontal plane Plane 9 which passes through the lowest point of the daylight opening forward of the pillar. The focus of the seminar is on the development process and the development tools and methods.

Locate the point Point 21 on the vehicle interior at the intersection of the horizontal plane passing through the highest point of the forward door opening and a transverse vertical plane Plane 32 tangent to the rearmost edge of the forward door, as viewed laterally with the adjacent door open.

Locate the point Point 13 at the intersection of Plane 26 and the upper edge of the forwardmost door opening. Using the same method, draw a line from Point b to Point d. Locate a horizontal plane Plane 40 half-way between Plane 38 and 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.

Measuring along the vehicle exterior surface, locate a point Point 1 on Line 1 that is mm inboard of the intersection of Line 1 and a vertical plane tangent to the vehicle at the outboardmost point on Line 1 with the vehicle side door open.

The maximum horizontal approach angle for the right A-pillar impact equals the angle formed by that line and the X-axis of the vehicle measured counterclockwise.

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 an upward angle of the same number of degrees with that plane.

If the horizontal line is tangent to the periphery at more than one point at any location, the most inboard point is the door opening. Locate a horizontal plane Plane 34 that passes through the lowest point of the adjacent daylight opening forward of the door frame.
