3.13
door hinges
assembly of components connected to the door and body, capable of rotating around the same axis and combined with each other
3.14
fully latched position
the position where the latch and striker are engaged when the door is fully closed
3.15
secondary latched position
the position where the latch and striker are engaged when the door is not fully closed
3.16
latched
any situation that the door lock is engaged in any of the following circumstances: fully latched position, secondary latched position or their middle position
3.17
pitch angle
angle between fixed straight line which connects two reference points on the left front or right front sills (if applicable) and the horizontal plane (Figure 1)
Figure 1 Schematic diagram of linear connection of two reference points on the left sill
3.18
roll angle
angle between fixed straight line which connects two reference points on both sides of longitudinal centerline of the vehicle and front or rear plane of vehicle body (if applicable) and the horizontal plane (Figure 2)
Figure 2 Schematic diagram of linear connection of two reference points
on the rear part of body
3.19
unladen attitude
attitude corresponding to pitch angle and roll angle of test vehicle at the unladen mass when the test vehicle is placed on a horizontal plane and all tyres are inflated to the pressure specified by the manufacturer
3.20
reference attitude
attitude corresponding to pitch angle and roll angle of test vehicle at the reference mass when the test vehicle is placed on a horizontal plane and all tyres are inflated to the pressure specified by the manufacturer
3.21
test attitude
attitude corresponding to the pitch angle and roll angle of the test vehicle that will collide with the rigid pole
