Article 36.1
Rearward Intrusion Laminate Reference Surface - Profile Definition
Chapter: APPENDIX C3: DRAWINGS
In Simple Terms
This rule defines the shape of a protective barrier at the rear of the car that must meet specific geometric requirements. Think of it as an invisible safety profile that the car's rear structure must conform to, measured at three specific points to ensure the barrier provides proper protection in crashes.
- Defines a two-line profile on a vertical plane (Y=0) at the center of the car
- Three measurement points: one at the top center (X=0, Z=550mm), and two lower points at the side (X=-75mm at Z=450mm and Z=100mm)
- Creates a stepped or angled safety structure that protects the driver in rear-impact collisions
- Part of the technical safety specifications that cars must meet during inspection
Official FIA Text
On the plane Y=0, a profile of two lines passing through the following points [X, Z]; a. [X C = 0, 550], [X PU = −75, 450], [X PU = −75, 100].
