摘要:
The invention relates to an interface device between a boot and a ski for modifying in a dynamic manner the pressure distribution of the ski on the snow. The device includes two binding elements, a mobile sensor, a return rocking device, and an element affixed to the ski. The rocking device is arranged to transform a vertical bias exerted on the sensor into a traction bias exerted on the element affixed to the ski. In reaction, a traction bias of the same type can be transmitted towards the rear of the ski.
摘要:
A device for modifying the pressure distribution of a ski such as especially an alpine ski over its gliding surface. The ski is equipped in its middle sole zone with at least one binding element adapted to retain a boot, and with at least one support element on which the sole of the boot rests. The device includes a stiffening blade that extends above the ski from the middle sole zone towards the front where it is affixed to the ski. It also includes a sensor element in contact with the sole of the boot, that is mobile along a vertical direction, and a connection between sensor element and stiffening blade, in order to transmit to stiffening blade, in the form of a force oriented along the horizontal and longitudinal direction of the blade towards the front, at least a portion of the downward vertical thrust of the boot captured by sensor element.
摘要:
A device for modifying the pressure distribution of a ski, such as especially an alpine ski over its gliding surface, as well as to a ski equipped with such a device. The ski is equipped with at least one binding element adapted to retain a boot in the central zone of the middle sole, and at least one support element on which the sole of the boot rests. Moreover, the ski includes a lower base, and above the base, a stiffening blade, both of whose ends are fixedly connected to the base at the front and rear of the middle sole zone. The device includes, in addition, a sensor element in contact with the sole of the boot, mobile along a vertical direction. It also includes a connection between the sensor element and stiffening blade in order to transmit to the blade, in the form of at least one longitudinally or horizontally oriented force in the direction of either one and/or the other of its ends, at least a portion of the downward vertical thrust of the boot captured by sensor element.
摘要:
A ski including a first sub-assembly or base having its own distribution of stiffness and a second upper sub-assembly or stiffener connected to the base by means of flexible and/or partially rigid connections. The stiffener includes two parts separated and spaced from one another by a short distance when the ski is at rest. The two parts cooperate with each other when the ski is biased flexionally in certain functional conditions so as to increase the stiffness of the ski.

Shock absorption device adapted to damp the vibrations of a ski, comprising at least one flexion blade that includes a first portion fixed to the ski and a second portion connected to the ski in a longitudinally mobile manner by a friction device.
摘要:
A ski having a sole equipped with discontinuous serrations comprising a smooth or lightly structured front portion and a strongly structured rear portion. The rear portion extends towards the rear in the direction of rear contact line from a transverse line located between the boot center line and a transverse line located at a distance (d) from the boot center line, equal to 0.4 times the distance (D) separating the line from forward contact line. The invention is more specifically related to an alpine ski whose ability to glide is thus improved.
摘要:
An improvement to known ski shock-absorption devices is constituted by an elongate beam having an arched portion of a length (LC) between a forward contact line and a rear contact line; the central portion including a binding mounting zone. The ski includes two transmitters located in the central portion and each on either side of the mounting zone. One of the ends of each transmitter is linked to the beam by a complete connection; the other end is connected by a partial connection, free in translation along a longitudinal direction, constituted of an elastic and/or visco-elastic element that resists the longitudinal displacement of the transmitter; the portion of length (l.sub.T1, l.sub.T2) of each transmitter between the two connections being left free, at least in translation, with respect to the beam; the ratio (l.sub.T1) of front transmitter over (l.sub.T2) of rear transmitter being comprised between 1.5 and 2.5 and (l.sub.T1 +l.sub.T2)/LC being comprised between 0.15 and 0.25.

摘要:
The invention relates to a ski equipped with a beam and a device intended to modify the stiffness and/or shock absorption of vibrations. The ski includes (1) at least one elongated element oriented longitudinally with respect to the ski, connected to the ski by a rigid linkage and which includes at least one free end, suited to be displaced longitudinally with respect to the ski when the ski is biased in flexion, and spaced longitudinally from the rigid linkage, and (2) a resistance device connected to the ski that cooperates with the free end in order to resist its displacement, the resistance force of the resistance device that resists the displacement of the free end decreasing between a minimum displacement position and a maximum displacement position. Such a ski maintains its stable qualities in a horizontal position and improves its pivoting and steering characteristics during tight turns.
