Abstract:
A boot/binding assembly for skiing wherein the binding releases in the event of falling both forward or backward and in response to twisting, the assembly comprises a boot whose sole is fitted with a transverse bar (38) and a binding which has a longitudinal direction and a transverse direction, said binding comprises a boot-retaining device (11, 29) for retaining the boot by said transverse bar, wherein the boot-retaining device located on the binding comprises a transverse recess (26) having a notch-shaped profile and which is formed between at least two retaining pieces (10, 19), said at least one retaining piece (10) can be moved longitudinally against the action of at least one spring (15, 16), and at least one self-locking cam (29) articulated about an axis transverse to the binding on one of the retaining pieces and experiencing a force tending to keep said transverse bar engaged in the transverse recess (26), said self-locking cam having a cylindrical convex face (31) being interfaceable with the transverse bar (38) such that the transverse bar, once engaged in the transverse recess after having deflected the self-locking cam, tends to move the self-locking cam with said transverse bar by friction when an upward force is exerted on the transverse bar, so that the transverse bar stays locked in the transverse recess by wedging between the self-locking cam and the retaining piece (10) which is not supporting the self-locking cam.
