• seats in particular with regard to their spatial arrangement, can be adapted to the diverse uses.
• a vehicle seat is known from US Pat. No. 6,000,742 in which three positions of the seat are provided.
• a useful position of the seat is provided
• a loading position is also provided in which the seat frees up as much loading space as possible
• a folding position is also provided which allows access to a vehicle area located behind the vehicle seat in a convenient manner.
• a complicated mechanism for folding away the seat is provided, which is also fully within the force path that is used in an accident of the vehicle. It is therefore necessary to implement the complicated folding mechanism in a very stable and long-lasting manner in order not to raise any safety problems due to the variable design of the vehicle seat.
