Definitions

  • helmets For protection from head injury.
  • Body harnesses such as shoulder pads or other devices, are also sometimes worn for protection.
  • these devices do an adequate job of protecting the head or body from direct impact and crushing or penetrating injuries, the head is free to move and rotate rapidly with respect to the body. Unconstrained movement of the head may result in so-called whiplash or rotational brain injury, a major cause of serious brain damage.
  • helmets have been extensively developed to protect the head from crushing and penetrating injuries, helmets do not protect against the very serious rotational or whiplash injuries in which the impact causes the head to rotate rapidly with respect to the body around the neck.
  • the head may not appear to be damaged in such an impact situation, the rapid rotation or whiplash motion can cause the brain to move within the cranium and be severely damaged. Such apparently “hidden” damage can lead to severe permanent impairment or death.
  • the present invention describes various apparatus and methods to prohibit user injury from sudden impact or rotational or whiplash movement.
  • the invention may prohibit injury to the head and neck, and specifically, injury to the brain caused by sudden rotational acceleration or deceleration of the head.
  • an apparatus in an embodiment of the invention, includes a helmet, a body harness configured to secure to a user, a plurality of tethers and a plurality of spools.

  • a plurality of spools are arranged such that each tether is in wound engagement with one of each of the plurality of spools.
  • An exemplary spool 30 is shown in Figure 5, with a tether 32 wound around the center groove of a spool 30.
  • An end 34 of the tether 32 is secured to the spool by any suitable means.
  • the spool allows movement of the tether 32 in an unwinding direction Ai and an opposite winding direction, but biased to rewind the tether in the opposite winding direction.
  • acceleration at a pre-determined level of the tether 32 in the unwinding direction A ⁇ will activate a locking mechanism.
  • the locking mechanism of each spool operates independently of the locking mechanism of one or more other spools. In other words, movement of the football helmet 12 of a user may initiate the locking of none, one, all, or a plurality of tethers.
  • the spools are located along the length of the tether and at a position between the helmet and the body harness. In one embodiment, the spools are fixed to either the top surface or the bottom surface of the shoulder pads. Alternatively, the spools may be disposed within the shoulder pads, with the pads having a structural accommodation, such as a slit, for the tether.

  • the apparatus includes a spool and locking mechanism to prohibit tether movement. It should be understood by other with ordinary skill in the art that various conventional spool and locking mechanism designs can be used in the practice of this invention. An exemplary spool 30 and locking mechanism 40 will now be discussed.
  • FIGS 6a and 6b Cross-sectional views of the spool of Figure 5 are shown in Figures 6a and 6b.
  • An unlocked condition is shown in Figure 6a and a locked condition is shown in Figure 6b.
  • two identical locking mechanisms 40 are disposed in the spool. It should be apparent to those with ordinary skill in the art that the number of and location of the locking mechanisms may vary in the practice of this invention.
  • the locking mechanism 40 includes a mass 42, lever 44, arm 46 and center stationary shaft 48.
  • the entire spool assembly 30 will spin except for the stationary shaft 48, which is held in place relative to the shoulder pads 14.
  • the tether 32 will unwind and rewind to accommodate movement of the user's head.
  • the mass 42 will move, or roll, radially outward by centrifugal force, to compress a main spring 50.
  • the mass 42 will lift the lever 44, which is normally biased inward by a second spring 52.
  • the second spring 52 is less stiff than the main spring 50, so the mass 42 is able to lift the lever 44, thereby pivoting the lever 44 about a point 54 to subsequently push the arm 46 radially inward. Teeth on the inward end of the arm 46 mesh with the teeth on the stationary shaft 48 As the arm 46 is moving down, or inward, it also ratchets with the internal walls of the spool, thus preventing the arm from being moved back up as it contacts the teeth of stationary shaft 48. When the unsafe movement ends, such as for example, the acceleration of the user's head stops, the arm 46 will return to an unlocked condition. It should be apparent to those with ordinary skill in the art that other locking mechanisms to prohibit tether movement may be utilized in the practice of this invention, such as for example, a centrifugal clutch of a conventional seat belt locking mechanism.
  • FIG 7 is a perspective view of an exemplary fastener 60.
  • the fastener includes a base plate 61 which defines two slots 62, 64. Screws or other hardware can be inserted through the slot and corresponding mounting locations of the helmet to mount the fastener to the helmet surface.
