Abstract: In a motor car of the type with three front seats side by side the central front seat is set further back than the other two front seats in order to provide adequate lateral restraint for the occupant of that seat when travelling. The passenger compartment of the car also has two separate rear seats whose median planes are slightly inclined to the vertical median plane of the car so that they diverge forwardly. The rear seats are spaced apart so as to leave space between them which is partially occupied by the central front seat. Maximum comfort and a large amount of available space are thus afforded for all five passengers, while the body can have quite small external dimensions. Preferably, the rear seats can be folded down in order to provide a large loading surface accessible through the rear hatch of the car.
