ABSTRACT:
The boot comprises an upper (4) hinged (5) with a shell (1). A mechanism allows the upper to be locked to the shell or to be pivoted. This mechanism consists of two links (7, 8) hinged with each other and, on the one hand, with the shell (10) and, on the other hand, with the upper (11). The pin (9) hingeably connecting the links together is accommodated, on the one hand, inside a notch (19b) in the top link (8) and, on the other hand, in a fixed oblong aperture (16). The notch (19b) leads into an oblong aperture (19a) in the top link (8). The mechanism is kept in this locked position by a spring (26). A lever (27) enables the oblong aperture (19a) to be brought opposite the hinging point (9) so that this pin is able to slide inside the superimposed apertures (16, 19a).
