Seating Layout & Passenger Capacity
Passenger capacity is not calculated only by counting seats. A correct seating layout must balance seat pitch, aisle width, entrance position, wheelchair area, luggage requirements, axle load limits, body structure, emergency access and homologation requirements. TLG SYSTEMS supports bodybuilders with practical seating layouts that are feasible for production, passenger use and regulatory approval.
Passenger layout engineering
The seating plan is developed around the real vehicle package. Door position, wheel arches, driver area, rear overhang, luggage volume, wheelchair zone and axle load balance must be evaluated together before the final passenger capacity is confirmed.
What we define in this phase
The purpose is to create a realistic passenger layout that supports the target capacity without creating problems in access, axle load balance, emergency movement, body structure or homologation.
- Seat count and seat pitch Practical seat arrangement based on vehicle length, floor level, aisle width and customer target.
- Passenger circulation Aisle, entrance, driver partition, handrail and priority area relationship.
- Wheelchair and priority area Space planning for accessible layouts, wheelchair bay, foldable seats and passenger access path.
- Luggage and service volume Seating capacity is checked together with luggage space, service compartments and equipment location.
- Axle load sensitivity Passenger distribution is reviewed together with front/rear axle capacity and body weight assumptions.
- Homologation preparation Layout direction is prepared with vehicle class, passenger area and applicable approval documentation in mind.
Maximum Capacity Is Not Always the Best Layout
A layout with too many seats may reduce comfort, create poor passenger flow, overload an axle or create approval problems. The correct target is a sellable and feasible capacity.
Door and Step Position Changes Everything
The entrance location affects the first row, driver area, aisle, standing or priority space, luggage position and passenger circulation.
Axle Loads Must Be Considered Early
Passenger positions, luggage space, HVAC, battery or fuel systems and body structure must be reviewed before finalising the seating plan.
| Review Area | Key Questions | Engineering Output |
|---|---|---|
| Passenger Capacity | What is the realistic seat count for the intended vehicle length, chassis wheelbase, door position and passenger comfort target? | Preliminary seating capacity, layout variants and feasibility notes. |
| Seat Pitch & Aisle | Can the required seat pitch, aisle width and passenger movement path be achieved without compromising usability? | Seat pitch direction, aisle arrangement and passenger circulation layout. |
| Entrance & Door Area | Does the door opening, step area and handrail position work with the seating layout and passenger flow? | Entrance-zone package, first-row position and access geometry direction. |
| Wheelchair / Priority Area | Is there enough space for wheelchair access, priority seating, foldable seats or special passenger arrangements? | Accessible layout proposal and passenger area configuration. |
| Weight Distribution | Does the passenger layout create front or rear axle load risk when combined with luggage, body weight and equipment? | Early axle load sensitivity review and mass distribution notes. |
| Homologation Direction | Does the layout support vehicle class requirements, passenger safety expectations and documentation preparation? | Approval-oriented layout direction for later CAD, COC and homologation preparation. |
