must be removed. When evaluating the specified radii the proportions and properties attributable to the materials of the roof lining shall be taken into consideration. The roof testing area shall extend in front of and above the transverse plane limited by the torso reference line of the manikin placed on the rearmost seat.

Paragraph 5.4.2.1.

(See para. 5.1.1. for definition of "sharp edges").

The downward projection shall be measured normal to the roof in accordance with annex 6, paragraph 1.

The width of the projecting part shall be measured at right angles to the line of the projection. In particular the rigid roof sticks or ribs shall not project away from the inner surface of the roof more than 19 mm.

Paragraph 5.5.

Any roof ribs on opening roofs must meet paragraph 5.4. if they are contactable by a 165 mm diameter sphere;

Paragraphs 5.5.1.2., 5.5.1.2.1., 5.5.1.2.2.

The opening and operating devices when in a position of rest and with the roof closed must meet all of the specified conditions.

Paragraph 5.5.1.2.3.

The force of 37.8 daN is applied even if the original projection is 25 mm or less. The projection is measured under the applied load.

The force of 37.8 daN applied in the direction of impact defined in annex 4 as the tangent to the trajectory of the headform is normally applied by means of a flat-ended ram of not more than 50 mm diameter, but where this is not possible an equivalent method may be used; for instance, by removing obstacles.

The "position of rest" means the position of the operating device when it is in the locked position.

Paragraph 5.6.

The rod system of convertible tops does not represent a roll-over bar.

Paragraph 5.6.1.
The top part of the windscreen frame starts above the transparent contour of the windscreen.

Paragraph 5.7.1.1.

See paragraph 5.1.1. for definition of "sharp edge".

Paragraph 5.7.1.2.

In defining the head impact zone of the back of the front seats any structure necessary to support the seat back shall be considered as a component of this seat back.

Paragraph 5.7.1.2.3.

The padding of the seat frame structure shall also avoid dangerous roughness and sharp edges likely to increase the risk of serious injuries to the occupants.

ANNEX 1,
DETERMINATION OF THE HEAD-IMPACT ZONE

Paragraph 2.1.1.2.

The choice between the two procedures for determining height is to be left to the manufacturer.

Paragraph 2.2.

When determining points of contact, the length of the arm of the measuring apparatus is not changed during a particular operation. Each operation starts from the vertical position.

Paragraph 3.

The 25.4 mm dimension means the measurement from a horizontal plane passing through the "H" point to the horizontal
