Seat

Seat identity for 3 rows with 3 seats per row,

front to back

the

front of vehicle from within the vehicle

General: Seating accounts for over 1/5th of VSS.yaml. This is due to the many facets of seating and the number of instances.

Seat Configuration:

Vehicle.Cabin.

SeatRowCount - number of rows - defaults to 2

.SeatPosCount - array of number of seats per row - defaults to 2,3 which is 2 in row 1 and 3 in row 2

Note:

Even though the default says only 2 seats in row 1, generated (yaml) it has Driver, Middle and Passenger

Related:

Vehicle.VehicleIdentification.VehicleSeatingCapacity - provides seating capacity vehicle

Vehicle.Cabin.DriverPosition - driver left, middle or right
