The rigid pole shall be stationary. The upper roof of a vehicle is determined according to the procedure specified 2001 S8. Locate the point Point 19 at the intersection of the surface of the upper vehicle interior, Plane 29 and the plane, described in S8. The load placed in the cargo area is centered over the longitudinal centerline of the vehicle.

Once the input model is checked for errors by the automated process, it can be submitted to a solver without any user intervention regulaation analysis and report generation. Target BP3 is located in accordance with this paragraph. Target DF3 is the point located in Plane 35 and on the interior surface of the door framewhich is closest to CG-F2 for the nearest seating position.

Movable windows and vents tmvss be placed in the fully open position. S8 Target location and test conditions.

Motor vehicle safety standards are getting to be more demanding with time. If the test configuration requires that the vehicle be elevated off the ground, the pretest vehicle attitude must be maintained. Locate a transverse vertical plane Plane 37 passing through Point 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 free motion headform contact with components rearward of this plane.

If a seat belt anchorage is located on the stiffenerTarget ST2 is any point on the anchorage. 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.

Convertible means a vehicle whose A-pillars are not joined with the B-pillars or rearmost pillars by a fixed, rigid structural member. Door frame means the rearmost perimeter structure, including trim but excluding glass, of the forward door and the forwardmost perimeter structure, including trim but excluding glass, of the rear door of a pair regulatioon adjacent side doors that:.

Locate the A-pillar reference point Point APR at the intersection of the interior roof surface and a line that is perpendicular to the vehicle regulationn surface at Point 2. 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 fmss structure as viewed laterally.

Locate the contour line Regklation 2 on the vehicle interior trim which passes through the APR and is parallel to the contour line Line 3 at the upper edge of the windshield on the vehicle interior. 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.

Ambulance means a motor vehicle designed exclusively for the purpose of emergency medical care, rsgulation evidenced by the presence of a passenger compartment to accommodate emergency medical personnel, one or more patients on litters or regulatuon, and equipment and supplies for emergency care at a location or during transport.

At the time of launch, the midsagittal plane of the headform is vertical and the headform is upright. For openings on the front and rear of the vehicle, other than a door openingdaylight opening means the locus of all points where a horizontal lineparallel to the vehicle longitudinal centerline, is tangent to the periphery of the opening.

Any added test equipment shall be located away from impact areas in secure places in the vehicle. The rearmost pillar reference point Point RPR is at the midpoint of the line between Point 7 and Point 8, measured along the vehicle interior.

If the seat belt mounting structure is below a horizontal plane passing through CG-F2 for the right seat, locate the point mm directly below that CG-F2 and locate a line formed by the shortest horizontal distance between that point and the right seat belt mounting structure.

Door opening means, for door openings on the side of the vehicle, the locus of all points where a horizontal lineperpendicular to the vehicle longitudinal centerline, is tangent to the periphery of the side door opening. Except as provided in S The Y coordinate is negative to the left of the X-Z plane and positive to the right. For components for which Table 1 specifies a range of angles, the headform launching angle is within the limits determined using the procedures specified in S8.

Where the term a is the resultant head acceleration expressed as a multiple of g the acceleration of gravityand t1 and t2 are any two points in time during the impact which are separated by not more than a 36 millisecond time interval.

To prevent injuries resulting from impacts of the occupants ‘ heads on vehicle interior parts, these parts need to be designed in a way which allows sufficient deformation space to reduce the loads on the head. Locate the point Point 22 at the intersection of the interior roof surface, Plane 32, and the plane, described in S8. 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.

Occupant knee impact simulations are performed in the automotive industry as an integrated design process during the course of instrument panel IP development. In particular the interaction of testing and simulation will be described and different design solutions will be discussed.

All interior compartment door assemblies with a locking device must be tested with the locking device in an unlocked position. If the anchorage has distinct adjustment positions, none of which is midway between the two extreme positions, tests are conducted with the anchorage adjusted to the nearest position above the midpoint of the two extreme positions. The position of the dummy is then measured as follows.

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

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. Each interior compartment door assembly located in an instrument panel, console assembly, seat back, or side panel adjacent to a designated seating position shall remain closed when tested in accordance with either S5.

Locate a longitudinal vertical plane Plane 30 at the mid-sagittal plane of a dummy seated in any outboard designated seating position. Target UR is any point on the upper roof.

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. This course is available as an in-house seminar.

49 CFR 571.201 – Standard No. 201; Occupant protection in interior impact.

Locate a transverse vertical plane Plane 12 passing through Point 5. The manufacturer shall select the option by the time it certifies the vehicle and may not thereafter select a different option for the vehicle. Locate a longitudinal vertical plane Plane 18 that passes through Point 9. Examples of practical solutions will be shown and discussed. Locate the horizontal plane Plane 3 which intersects regulatlon APR.

Initially, position adjustable seat backs in the manner specified in S8. Your contact person Dr. The objective of this course is to provide an overview of the legal requirements and to show how these can be fulfilled.
