ABSTRACT:
The boot is comprised of a shaft (12, 13) joined along a transverse axis (11) to a shell-base (10), and of a mechanism for controlling the stiffness of the pivoting movements of the shaft (12, 13) in relation to the shell-base (10). This mechanism incorporates, in the form of a double girder, two flexion arms (1,2) joined at one end, respectively, and attached to the shaft (12, 13) or to the shell-base (10) by means of an anchoring piece (3). The other end of each strip cooperates with an operating device (5) carried on the shell-base (10) or on the shaft (12, 13), respectively. The device (5) elastically produces variations in the degree of separation of the strips (1,2) in response to the force exerted by pivoting movements of the shaft (12, 13) in either direction.
