Definitions

  • the present disclosure relates to a protection assembly for protecting a user during a skiing activity, which is able to protect the knee joint and preferably prevent any injuries to the knee and/or to the lower limbs, for example in the case of movements which are dangerous for the knee joints or in the event of impacts and/or falls, or which is able to avoid the consequences of an impact or fall while skiing.
  • the present invention also relates to a ski apparatus.
  • the activity of skiing involves numerous risks for the safety of the skier.
  • the high speeds may result in sudden changes in direction and/or speed, which may be damaging for the knees, as well as loss of control which in turn results in dangerous movements for the skier and/or falls or impacts, which may lead to injuries, also of a serious nature.
  • a skier may be exposed to movements, falls, impacts and/or loss of balance which may result in different types of injury and/or damage for the skier.
  • knee protectors which are able to protect the knees of a user from injuries which are caused for example by falls, impacts or loss of balance due to the dangerous conditions typically associated with the skiing activity.
  • each protector takes into consideration only a single factor, without taking into account the various factors and the different causes which arise during the skiing activity and which may result in injury or damage for the skier, in particular for the knees and/or the lower limbs.
  • release devices are used, these triggering the release of the boot from the ski depending on the mechanical stress at the interface between the boot and the ski, so as to prevent possible injury to the knee and/or to the lower limb.
  • a further drawback of the prior art consists in the fact that, in order to avoid an undesirable releasing action for an expert user, namely a user able to withstand higher stresses than a user at the learning stage, the release system may be fixed or locked more tightly, with the risk, however, that it is unable to release the boot from the ski in the event of actual necessity and thus increasing the probability of an injury for the user.
  • a technical problem forming the basis of the present disclosure consists in providing an assembly for protection of a user which is therefore able to overcome said drawback and/or achieve further advantages.
  • a protection assembly according to the respective independent claim.
  • a ski apparatus including an assembly, as described and claimed, and at least one ski.
  • the present disclosure relates to a protection assembly for protecting a user, preferably during the skiing activity.
  • the assembly comprises a knee protector configured to assume an active knee protection condition and a non-active condition or rest condition.
  • the active condition may envisage the presence of an inflated inflatable bag or inflated airbag for protecting the knee
  • the non-active condition may envisage that the same inflatable bag or airbag is deflated or only partially inflated.
  • the protector may include, o be formed by, a knee containing structure, and an active protection condition may be a condition of greater rigidity of the containing structure so as to limit the movements and/or the loads acting on the knee.
  • the assembly further comprises a first actuator connected to the knee protector for changing a condition of the knee protector from the non-active protection condition into the active condition and vice versa.
  • a first actuator connected to the knee protector for changing a condition of the knee protector from the non-active protection condition into the active condition and vice versa.
  • the protector includes an inflatable bag
  • a gas generator according to the prior art may be envisaged, said gas generator being configured to inflate a bag or airbag so as to cause the knee protector to pass from the non-active condition into the active condition.
  • the gas generator is therefore to be understood as being a first actuator.
  • an actuator may be provided for making the containing structure more rigid, for example by means of suitable tie members.
  • the assembly also comprises first sensors configured to detect data relating to the knee or knees, said knee or knees data being kinematic and/or dynamic data and/or load data relating to the knee or knees.
  • the first sensors may detect and/or allow determination of the position, speed and/or accelerating force acting on the knee, or loads acting on the knee, preferably acting on the knee joint, so as to detect useful data regarding the safety state of the said knee.
  • the first sensors may be arranged on a leg or thigh and/or on the knee of both the lower limbs, or on a single lower limb, or more generally on at least one of the lower limbs of a user, or may be arranged in the vicinity of other parts of the body of a user or of the equipment worn by the user, and be in any case suitably calibrated in order to detect conditions and/or data relating to the knee or knees.
  • the assembly also comprises a first control device connected to the knee protector and to the first sensors.
  • the first control device is operatively connected to the knee protector and to the first sensors, for example so as to favour the exchange of data and/or signals.
  • the assembly further comprises a coupling and uncoupling device configured to connect in a detachable manner or disconnect a ski boot to/from the respective ski.
  • the coupling and uncoupling device may disconnect the boot from the respective ski or may reconnect the boot in a detachable manner to the respective ski.
  • the coupling and uncoupling device may be configured to disconnect the boot directly from the ski or may be configured to disconnect a first portion of the boot, configured to be associated with the user, from a second portion of the boot, configured to be associated with the respective ski.
  • the coupling and uncoupling device may disconnect the entire boot from the respective ski or may separate the second portion of the boot associated with the ski, for example a toe end of the boot, from the first portion of the boot associated with the user.
  • the coupling and uncoupling device is preferably also configured so as to be able to reconnect the boot to the ski in the same way.
  • the boot may be disconnected from the ski by means of a reversible modification of the structure and/or the geometry of the boot.
  • the coupling and uncoupling device is a device which allows the release of the user's foot, which is in turn associated with the boot, from the respective ski.
  • the assembly also comprises a second actuator connected to the ski coupling and uncoupling device and configured to operate the latter in order to release the boot from the respective ski.
  • the first control device is configured to process and/or evaluate data relating to the knee or knees, received from the first sensors, and, on the basis of this data, to emit a first signal for controlling or commanding at least one activation of the first actuator and modifying the condition of the knee protector. Furthermore, the first control device is configured to emit a second signal for controlling or commanding at least at least one activation of the second actuator and releasing the boot from the respective ski.
  • condition of the knee protector may be modified by means of a first signal which arrives from the first control device and the release of the boot from the respective ski may be realized by means of a second signal which is managed by the same first control device.
  • the main advantage of the assembly according to the present disclosure lies in the fact that the protection of a knee and/or a lower limb of a user may be optimized by means of a double control system, for both protection of the knee and release of the ski, and wherein the management of the signals for said double protection system is managed centrally by the first control device.
  • the reference number 100 denotes overall a protection assembly for protecting a user comprising:
  • the first control device 1c is configured to process and/or evaluate data received from the first sensors 10a and, on the basis of the data received from the first sensors 10a, to emit a first signal for controlling or commanding at least one activation of the first actuator 13 and modifying the condition of the knee protector 12 and/or to emit a second signal for controlling or commanding at least one activation of the second actuator 23 and releasing the boot from the respective ski.
