An emergency rescue equipment having a harmonic reflector circuit comprising an antenna connected to a non-linear circuit via a matching circuit and a casing that in part enclose the harmonic reflector circuit, wherein the harmonic reflector circuit is configured to receive a signal at a receive frequency (fRX), and configured to transmit said received signal at a transmit frequency (fTX), where the transmit frequency is a multiple of the receive frequency, the harmonic reflector circuit wherein the receive frequency (fRX) is in an interval from a first frequency to a second frequency, where the first frequency is at least 800 MHz; and the second frequency is at least 34 MHz larger than the first frequency; the received signal is transmitted at the transmit frequency (fTX) with an output power (Pout) of at least 70% of the maximum available output power (Pmax).

A ski boot composed of a lower part or foot portion and an upper part or leg portion, suitable to enclose the lower part of the skier's leg, wherein the leg portion is hinged to the foot portion so as to rotate with respect to the foot portion around hinges defining a rotation axis. The leg portion comprises a closing lever suitable to block and/or unblock selectively the rotation of the leg portion with respect to the foot portion, and operatively connected to a base and an arm engageable in abutment against a pin fixed to the foot portion. The closing lever in the open configuration mutually moves the base and the arm away from each other forcing the latter against the pin to prevent a rotation of the leg portion backwards. The boot comprises traction means which operatively connect the base, the arm, and a fastening on the foot portion, the arm being placed between the base and the fastening. Said traction means comprise a cable at least partially extensible.

An antistatic sport device includes a basic body and a basic element placed at the basic body, made of a running surface layer and side edges. At least one of the side edges forms a contacting surface that can be turned towards the terrain. Between a rear surface of the running surface layer and the basic body, a contacting element made of an electrically conductive material is placed at least in sections. The running surface layer is electrically conductively connected to the contacting element via a discharge path and further the contacting element to the contacting surface formed by the at least one side edge. Further, a sport system has antistatic function and a sport clothing system is for such sport system.

A ski boot (1) includes a base frame (2) for receiving a foot of a skier; a rigid sole (3) connected to the base frame (2); a shaft (4) for receiving a lower leg part of the skier, the shaft (4) being angularly variably connected to the base frame (2); and a traction element (12). The traction element is attached to the sole (3) and/or in a toe area of the base frame (2) and extends from there to a heel area of the sole (3). In the heel area, the traction element (12) is deflected towards the shaft (4) and is then attached to the shaft (4). By inclining the shaft (4) towards a toe region, the traction element (12) can be tensioned and, in particular, traction can be exerted on the sole (3) and/or the toe region.

A boot form for a hockey skate is made of multiple plastic materials having different hardness properties, or different flexural moduli, and is formed via an injection-molding process or another similar process. One or more of the plastic materials may be reinforced with fibers of glass, carbon, aramid, or another stiffening material to strengthen one or more regions of the boot form. For example, pellets of a first plastic material having a flexural modulus of approximately 190 MPa (e.g., a polyamide elastomer block amide) may be injected into a mold to form a softer upper region of the boot form. And pellets of a second plastic having a flexural modulus of approximately 20,000 MPa (e.g., a Nylon 12 with long glass fibers) may be injected into the mold to form a stiffer lower region of the boot form. Additional skate components may then be attached to the boot form.

The invention relates to an automatic heel unit (1) for a ski binding, comprising a base (7) for fitting the automatic heel unit (1) on a ski and a heel downholder (3) for holding down a ski boot in a heel region of the ski boot. The heel downholder (3) is mounted so as to be movable in relation to the base (7). The automatic heel unit (1) has a holding configuration in which the heel downholder (3) is located in a holding position and may interact with the heel region of the ski boot that is held in the ski binding in such a manner that the heel region of the ski boot is held down in a lowered position. Furthermore, the automatic heel unit (1) has a step-in configuration in which the heel downholder (3) is located in a step-in position and the heel region of the ski boot is released by the heel downholder (3). The automatic heel unit (1) comprises a heel support structure (6), which is configured separately from the heel downholder (3), for supporting, in a direction that is horizontally transverse to the ski, the heel region of the ski boot that is held in the ski binding in the holding configuration of the automatic heel unit (1).

A ski boot comprising: a rigid shell which is shaped so as to accommodate the foot of the user, and has a lower part structured to be able to couple to a ski binding device; a rigid cuff which is shaped so as to enclose the lower part of the leg of the user, and is pivotally joined to the shell so as to be able to swing about a rotation axis substantially perpendicular to the midplane of the boot; and a cuff locking device which is located on the cuff and is selectively adapted to rigidly connect the cuff to the shell to prevent the cuff from swinging on the shell; the cuff locking device, in turn, comprising a movable arm which is pivotally joined to the cuff so as to be able to rotate to and from a locking position in which the movable arm extends downwards and arranges its distal end in abutment on an anchorage structure present on said shell, and an elastic assembly which is adapted to bring and elastically retain the movable arm in the locking position, and which basically consists of a telescopic stem that lies substantially on the rotation plane of the movable arm and is interposed between the movable arm and a fixed point on the cuff, and of an elastic opposing member that is fitted on the telescopic stem, and acts on the telescopic stem so as to bring and elastically maintain the telescopic stem in a maximum extension configuration.
