Definitions

  • the present invention relates to a safety device for crash helmets for the purpose of preventing irregular movements, compression and rotation of the neck caused by accident trauma.
  • the present invention concerns a safety device for crash helmets for the purpose of preventing irregular movements, compression and rotation of the neck caused by accident trauma.
  • the present invention further concerns a safety device that can be integrated into already existing crash helmets or directly inserted into newly manufactured crash helmets.
  • the present invention seeks to provide a pneumatic safety device for crash helmets for the purpose of preventing irregular movements, compression and rotation of the neck caused by accident trauma.
  • This device can be integrated into already existing crash helmets by means of a hook or directly inserted into newly manufactured crash helmets.
  • the device is a streamlined structure having expandable, pneumatic appendages firmly attached to the external surface of a helmet and in perfect symmetry with the helmet's longitudinal axis.
  • Means for activating the expandable, pneumatic appendages are hinged to a support at the base of the helmet.
  • a compressed gas cylinder initiated by inertial sensors, is attached to a main valve that instantly allows for expansion of the appendages. The valve thereafter allows the air to flow out of the appendages in order to empty them completely. Because of the particular form, when the appendages are completely expanded, as well as pressing on the shoulders of the person wearing the helmet, they prevent compression of the neck by completely blocking the rotation of the head.
  • the device comprises two main inertial sensors.
  • One of the sensors has an oscillating mass and is highly sensitive to inclinations and violent accelerations.
  • the other sensor has a centrifugal mass and is activated by a cord that is sensitive to abrupt, sharp movements and links the device to a part of the motor vehicle.
  • the activation of the expansion of the protective appendages starts when the motorcyclist assumes an abnormal position or a violent acceleration.
  • the sensors detect the abnormal movements and activate expansion of the appendages. To avoid an undesirable activation of the appendages when the helmet is not in use, the activation of the two highly sensitive inertial sensors is inhibited by a manually operated safety device.
  • the integration of the device with crash helmets makes the helmets safer than conventional helmets and more suitable to reduce the severity of traumas caused by the violent impacts of the spinal column and irregular movements, compression and rotation of the neck, which motorcyclists involved in road accidents often undergo.
  • a safety device 2 for crash helmets characterized by a set of pneumatic appendages 3, 4, 5, 22 and 23 securely fastened to the surface of a helmet 1 with hooks 6 in perfect symmetry about a longitudinal dividing line of the helmet 1, is illustrated in Figure 1 and 2.
  • the appendages 3, 4, 5, 22 and 23 are expanded by means of inertial sensors 20 and 28 in accordance with a preferred embodiment of the present invention.
  • Chin appendages 22 and 23, shoulders appendages 3 and 5, a neck appendage 4, and a cylinder of compressed gas 7 are connected by tubing 15 with a main valve 9 adjoining the tubing 15.
  • the body of the main valve 9 is equipped with a calibrated opening in order to allow the flow of gas to all the protective appendages 3, 4, 5, 22 and 23 when tha gas is released from the cylinder.
  • the centrifugal mass sensor 28, comprised of two masses 21, is sensitive to pulls induced by a cord connected by a hook 27 to the chassis of a motor vehicle.
  • the centrifugal mass sensor 28 activates a spring 16 which, in turn, causes movement of two lever arms 10 and 11, thereby opening the main valve 9.
  • the oscillation ( ⁇ ) of a pole 12 connected to the helmet 1, consequently to the action of one of the two sensors 20 and 28, pushes the lever arms 10 and 11 in such a way as to open the main valve 9.
  • the two sensors 20 and 28, particularly studied to have specific functions have the ability to transmit their amplified forces through the lever arms 10 and 11, operating on the principles of the lever.
  • the oscillating mass sensor 20, which is sensitive to dangerous inclinations and violent accelerations is comprised of a rotating part having a ball bearing ring 25 and two diametrically opposed masses 18 and 19 that pivot about a point.
  • the closing of a valve 26 located at the junction of the tubing 15 and the cylinder of compressed gas 7, or the insertion of a blocking device 17, inhibits the release of the lever arms 10 and 11 put into action by the spring 16.
