Using the same method, draw a line from Point b to Point d. Locate a horizontal plane Plane 10 half-way between Plane 8 and Plane 9. The load placed in the regulatkon area shall be centered over the longitudinal centerline of the vehicle. Radii of these spheres are mm and mm, respectively.

Locate the point Point rwgulation at the intersection of the interior roof surface, Plane 32, and the plane, described in S8.

Head Impact on Vehicle Interiors: FMVSS 201 and UN R21

On the vehicle exterior, locate a transverse vertical plane Plane 1 which contacts the rearmost point of the windshield trim. If a range of horizontal approach angles is prescribed, position the forehead impact zone in contact with the selected target at any horizontal approach angle within the range which may be used for testing. Target FH1 is located at the intersection of Plane 18 and the upper vehicle interior, halfway between a transverse vertical plane Plane 19 through Point 9 and a transverse vertical plane Plane 20 through the intersection of Plane 18 and Line 3.

For rear outboard designated seating positions, the head center of gravity CG-R is located mm rearward, relative to the seat orientation, and mm upward from the seating reference point. Each vehicle shall be loaded to its unloaded vehicle weightplus kilograms pounds or its rated cargo and luggage capacity whichever is lesssecured in the luggage or load-carrying area, plus the weight of the necessary anthropomorphic test dummy.

It is not guaranteed to be accurate or up-to-date, though we do refresh the database weekly. The door frame reference point Point DFR is the point located at the middle of the line from Point 21 to Point 22 in Plane 32, measured along the vehicle interior surface.

Head Impact on Vehicle Interiors: FMVSS and UN R21 – Empowering Engineers

The headform used for testing conforms to the specifications of partsubpart L of this chapter. In a test in which the test vehicle is striking its right side, the dummy is to be configured and instrumented to strike its right side, in accordance with subpart M of part The minimum horizontal approach angle for the right seat belt mounting structure equals the angle formed by that line and the X-axis of the vehicle measured counterclockwise, or 90 degrees, whichever is less. Locate a horizontal plane Plane 41containing either CG-F2 or CG-R, as appropriate, for any outboard designated seating position whose seating reference pointSgRP, is forward of and closest to, the vertical center line of the width of the seat belt mounting structure as viewed laterally.

Free motion headform means a test device which conforms to the specifications of partsubpart L of this chapter. 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. To ensure compliance of this requirement, head impact tests are conducted at 12 and 15 mph for performance verification.

Locate a transverse vertical plane Plane 31 containing either CG-F2 or CG-R, as appropriate, for any outboard designated seating position. If the horizontal line is tangent to the periphery at more than one point at any location, the most inboard point is used to determine the daylight opening.

The maximum horizontal approach angle for the left B-pillar equals the angle formed by that line and the X-axis of the vehicle measured counterclockwise, or degrees, whichever is greater. 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.

The X coordinate is negative forward of the Y-Z plane and positive to the rear. If the required distance cannot be achieved through movement of the seat, the seat back angle is fmvas even further forward until the 50 mm 2 inches distance is obtained or until the seat back is in its fully upright locking position.

The HIC d shall not exceed when calculated in accordance with the following formula:. Convertible roof linkage mechanism means any anchorage, fastener, or device necessary to deploy a convertible roof frame.

The upper roof of a vehicle is determined according to the procedure specified in S8. The focus of the seminar is on the development process and the development tools and methods. Determination of impact locations in a vehicle Development process and methods Solving of conflicts of objectives Typical deformation paths, padding materials. Initially, position adjustable seat backs in the manner specified in S8. The maximum horizontal approach angle for the right seat belt mounting structure equals the angle formed by that line and the X-axis of the vehicle measured counterclockwise.

Regylation minimum horizontal approach angle for the left B-pillar regylation the angle formed by that line and the X-axis of the vehicle measured counterclockwise. A commercially available CAE process automation tool was used to automate these steps and regylation a head impact simulation model. The requirements do not apply to any target that can fmsvs be located using the procedures of S If a seat belt anchorage is located on the stiffenerTarget ST2 is any point on the anchorage.

It does not include a header.

Target DF4 is the point located in Plane 36 and on the interior surface of the door frame that is closest to CG-R for the nearest seating position. For altered vehicles and vehicles built in two or more stages, including ambulances and motor homes, any target located rearward of a vertical plane mm behind the seating reference point of the driver ‘s designated seating position tests for altered vehicles and vehicles built in two or more stages do not include, within the time period for measuring HIC dany regualtion motion headform contact with components rearward of this plane.

The minimum horizontal approach angle for the left seat belt mounting structure equals the angle formed by that line and the X-axis of the vehicle measured counterclockwise. Locate the point Point 4 at the intersection of the interior roof surface, Plane 7, and the plane, described in S8.

S5 Requirements for instrument panels, seat backs, interior compartment doors, sun visors, and armrests. This standard specifies requirements to regulaiton impact protection for occupants.
