Locate a transverse vertical plane Plane 12 passing through Point 5. Vehicles manufactured by final stage manufacturers on or after September 1, fmvsx, except as provided in S6. The front end of the line is designated as Point P. The HIC d shall not exceed when calculated in accordance with the following formula:.

Leg joints are adjusted with the torso in the supine position. 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.

Convertible means a vehicle whose A-pillars are not joined with the B-pillars or rearmost pillars by a fixed, rigid structural member. Once critical impact locations are identified, CAE simulations performed which is a repetitive process that involves computing fmcss angles, positioning the rigid head form with an assigned initial velocity and defining suitable contacts within the finite element model. Each armrest that folds into the seat back or between two seat backs shall either:.

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

Locate the rrgulation plane Plane 5 containing the highest point at the intersection of the dashboard and the A-pillar. Determine the intersection points, if they exist, of the small sphere surface, the horizontal plane, and the vehicle interior surface. Locate the contour line Line 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.

Locate a longitudinal vertical plane Plane 18 that passes through Point 9. The distance between Point M, as described in Fvss.

Other door frame means the rearmost perimeter structure, including trim but excluding glass, of regulatiln forward door and the forwardmost perimeter structure, including trim but excluding glass, of the rear door of a pair of adjacent side doors that:.

The maximum fvss approach angle for the right door frame equals the angle formed by that line and the X-axis of the vehicle measured counterclockwise. Doors, including any rear hatchback or tailgate, shall be fully closed and latched but not locked.

The maximum horizontal approach angle for the left seat rdgulation mounting structure equals the angle formed by that line and the X-axis of the vehicle measured counterclockwise, or degrees, whichever is greater. Table 1 – Approach Angle Limits in Degrees. Locate the point Point 24 at the intersection of the interior roof surface, Plane 37 and the plane, described in S8.

The impact reference line shall be aligned with the center line of the rigid pole so that, when the vehicle-to-pole contact occurs, the center line of the pole contacts the vehicle area bounded by two transverse vertical planes 38 mm 1. Convertible roof linkage mechanism means any anchorage, fastener, or device necessary to deploy a convertible roof frame.

In addition, the development according to the head impact requirements in the overall-context of vehicle development is described in this seminar. Dynamically deployed upper interior head protection system means a protective device or devices which are integrated into a vehicle and which, when activated by an impact, provide, through means requiring no action from occupants, protection against head impacts with upper interior structures and components of the vehicle in crashes.

The requirements do not apply to any targets that cannot be located by using the procedures of S Stiffener means a fixed overhead structural member that connects one roll-bar to another roll-bar or to a header of any open body vehicle or convertible.

Target BP3 is the point located in Plane 10 and on the interior surface of the B-pillarwhich is closest to CG-F 2 for the nearest seating position. National Highway Traffic Safety Administration. 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 through the highest point of each door or daylight opening.

Any sunroof shall be placed in the fully closed position. 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. Additionally, any interior compartment door located in an instrument panel or seat back shall remain closed when the instrument panel or seat back is tested in accordance with S5. The load placed in the cargo area shall be centered over the longitudinal centerline of the vehicle.

Locate a horizontal plane Plane 14 passing through the lowest point of the daylight opening forward of the pillar. Free motion headform means a test device which conforms to the specifications of partsubpart L of this chapter. Locate the point Point 18 as provided in S The vehicle shall be tested and the targets specified in S10 located under the following conditions. Locate a horizontal plane Plane 10 half-way between Plane 8 and Plane 9.

Each installed armrest shall conform to at least one of the following:. Each foot of the test dummy is equipped with a size 11EEE shoe, which meets the configuration size, sole, and heel thickness specifications of MIL-S and weighs 0. The headform used for testing conforms to the specifications of partsubpart L of this chapter. 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.

Regukation area of the vehicle to be impacted by the headform is marked with a solid circle The minimum horizontal approach tegulation for the left B-pillar equals the angle formed by that line and the X-axis of the vehicle measured counterclockwise.

On the vehicle exterior, locate a transverse vertical plane Plane 1 which contacts the rearmost point of the windshield trim. Construct a line in the plane that contains the rearward point of the front door daylight opening fmvsz is perpendicular to the longitudinal vehicle centerline.

Locate the point Point 15 as provided in either S Locate a horizontal plane Plane 39 passing through the lowest point of the daylight opening regjlation of the door frame. Your contact person Dr.

Movable windows and vents shall be placed in the fully open position. The minimum regulatipn approach angle for the right A-pillar equals degrees minus the angle formed by that line and the X-axis of the vehicle, measured counterclockwise.

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