Front passenger seat in vehicles of category X (para. 2.6.1.)

Paragraph 2.6.1. defines a front passenger seat by the vertical transverse plane through the driver's R point. A new sentence says that, for vehicles of category X, the R point of the most forward passenger seat must be used instead. The rest of the definition does not change.

"Front passenger seat" means any seat where the "foremost H point" of the seat in question is in or in front of the vertical transverse plane through the driver's R point; For vehicles of category X, the "R" point of the most forward passenger seat shall be taken instead of the R-point of the driver's seat.
