i have just bought a focus st which is on log book as a four seater can i get a extra seat belt fiitted and be legal as a five seater
Log Book? Do you mean if you added an extra belt, you would save on insurance costs? No, don't do, the seat wasn't designed to carry an extra passenger and you won't save any money.
Automobile seat load carrying specifications were established for the 1968 model year. Those specifications are still in place today. Each seating position in the vehicle is designed to carry 150 pounds. So, as Tom said, don't do it. In the event of an accident serious injury may occur because the seat is overloaded and the extra seatbelt not properly anchored. A typical 6 passenger vehicle, for example, is designed to carry a full load of 1100 pounds. That's 900 pounds of passengers and a 200 pound load in the trunk. Exceeding that also risks tire failure and other failures as well. Be safe!! Don't overload your vehicle!! It's too risky!! HTH. -Jim
