Locate the point Point 13 at the intersection of Plane 26 and the upper edge of the forwardmost door opening. We are using cookies to give you the best experience on our site. The front end of the line is designated as Point P. To ensure compliance of this requirement, head impact tests are conducted regulatjon 12 and 15 mph for performance verification. This course is available as an in-house seminar. Locate the point Point 24 at the intersection of the interior roof surface, Plane 37 and the plane, described in S8.
Locate a longitudinal vertical plane Plane 18 that passes through Point 9. The top, if any, regulattion convertibles and open-body type vehicles shall be in the closed passenger compartment configuration. 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.
Viewing 1 to 4 of 4. Initially, position adjustable seat backs in the manner specified in S8. If a seat belt anchorage is located on the roll-barTarget RB2 is any point on the anchorage.
Target BP4 is the point located in Plane 11 and on the interior surface of the B-pillar which is closest to CG-R for the nearest seating position. Determination of impact locations in a vehicle Development process and methods Regulatiln of conflicts of objectives Typical deformation paths, padding materials. The other pillar reference point Point OPR is the point located at the middle of the line between Point 5 and Point 6 in Plane 12, measured along the vehicle interior surface.
Target RP2 is located in Plane 17 and on the pillar at the location closest to CG-R for the nearest designated seating position. For front outboard designated seating positions, the head center of gravity with the seat in its rearmost normal design driving or riding position CG-F2 is located mm rearward and mm upward from the regulatio reference point.

Leg joints are adjusted with the torso in the supine position. The top, if any, of convertibles and open-body type vehicles is in the closed passenger compartment configuration. Locate a horizontal plane Plane 39 passing through the lowest point of the daylight opening forward of the door frame. All major automakers have different categories of dynamic testing methods as part of their design process in validating their designs against the FMVSS requirement.
Locate a longitudinal vertical plane Plane 30 at the mid-sagittal plane of a dummy seated in any outboard designated seating position.
The rigid pole is a vertical metal structure beginning no more than 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. 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. Locate a transverse vertical plane Plane 31 containing either CG-F2 or CG-R, as appropriate, for any outboard designated seating position.
For front outboard designated seating positions, the head center of gravity with the seat in its forwardmost adjustment position CG-F1 is located horizontally forward of CG-F2 by the distance equal to the fore-aft distance of the seat track.
Both regulations stipulate requirements concerning the maximum head acceleration or the HIC in impacts on interior parts. Any added test equipment shall be located away from impact areas in secure places in the vehicle.
A commercially available CAE process automation tool was used to automate these steps and generate a head impact simulation model. The requirements do not apply to any targets that cannot be located by using the procedures of S For door openings on the back end of the vehicle, door opening means the locus of all points where a horizontal lineparallel to the vehicle longitudinal centerline, is tangent to the periphery of the back door opening.
Measure the longitudinal distance between the rearmost point on the dummy head and this line. Your contact person Dr. Locate a horizontal plane Plane 36 half-way between Plane 34 and Plane This has given rise to a corresponding number of knee impact simulations performed at various stages of product development. The manufacturer shall select the option by the time it certifies the vehicle and may not thereafter select a different option for the vehicle.
Target OP2 is the point located on the interior surface of the pillar at the intersection of Plane 15 and the centerline of the width of the pillaras viewed laterally. Target FH2 is located at the intersection of Plane 21 and the upper vehicle interior, halfway between a transverse vertical plane Plane 22 through Point 10 and a transverse vertical plane Plane 23 through the intersection of Plane 21 and Line 3.
This standard specifies requirements to afford impact protection for occupants. Each armrest that folds into the seat back or between two seat backs shall either:. Locate the horizontal plane Plane 3 which intersects point APR.
Head Impact on Vehicle Interiors: FMVSS 201 and UN R21
Windshield trim means molding of any material between the windshield glazing and the exterior roof surface, including material that covers a part of either the windshield glazing or exterior roof surface. For components for which Table 1 specifies a range of angles, the headform launching angle is reghlation the limits determined using the procedures specified in S8.
This standard applies to passenger cars and to multipurpose passenger vehiclestrucks, and buses with a GVWR of 4, kilograms or less, except that the requirements of S6 do not apply to buses with a GVWR of more than 3, kilograms. Table 1 – Approach Angle Limits in Degrees. 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.
