Abstract: The display of n+m symbols is achieved by means of an upper disk (1a), placed behind an aperture (2) in a cover plate, and of a lower disk (1b), placed behind the upper disk and comprising m sectors.One sector of the upper disk (1a) consists of a transparent window (4), the other n+m sectors of the two disks bearing the symbols.A gear-train (11, 12a, 12b, 13a, 13b) and a control cam (20), set in motion by a rotary driving member (10), cause the disks to rotate in steps of one sector, starting from a position in which the window (4) is located behind the aperture (2), such as to cause first the two disks to move forward together by one step, then the upper disk (1a) to move forward n successive steps, and finally the lower disk (1b) to move forward m-1 successive steps to return to the starting position.A positioning device (30a, 30b, 31a, 31b) blocks the disks (1a, 1b) when they are stationary, and releases them when required to move forward.

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.
