Definitions

  • the invention relates to safety helmets.
  • the invention relates more particularly to safety helmets having collars for use during sports activities, see e.g. document CH-A-637 547.
  • the helmet is designed to protect the skull of a wearer against blows and other impacts likely to be experienced in accidents. Serious damage can also be experienced if the neck over-flexes in an accident so that the nerve roots especially at the sides of the neck are damaged due to over tilting of the head. Tears of these delicate nerve roots cannot be repaired by present day surgical techniques and so can leave the arm at the side of any tears permanently paralysed.
  • Austrian Patent Specification No. 305114 discloses a cushioned collar. However, it is not constrained to prevent over-tilting of the head or incorporated into a helmet.
  • a safety helmet incorporating a collar including two cushions each arranged to be worn in line and below a respective ear of a wearer wherein the cushions are arranged to be separated from the surface of the neck and rest on the shoulder of the wearer so as to restrain excessive lateral tilting of the head to prevent nerve root severance in opposite lateral cervical regions of the neck.
  • a third cushion may be positioned centrally at the back of the neck and separated from the surface of the neck.
  • Each cushion may comprise an inflatable compartment formed in the collar.
  • the compartments are preferably connected together by air passages and have a common inflation nozzle.
  • the cushions are preferably positioned in use about 5 cms from the surface of the neck and are about 12 cms in height.
  • the safety collar 10 for the helmet comprises lengths of material with overlaying flaps 11 and 12, provided with a Velcro (trade mark) closures (not shown), which fits in use around the neck of a wearer.
  • Three air bags 13, 14 and 15 are formed inside the material of the collar and connected by pipes (not shown) to a common inflation nozzle 16.
  • the air bags are formed of durable plastics material and inflated during use of the collar.
  • the collar is designed so that all the air bags, or at least the bags 13 and 15, are positioned a few centimetres away from the neck and prevent excessive side tilting of the head of a user, the bags rest on the shoulder of the user. Some separation is necessary firstly to allow reasonably unimpeded or natural tilting of the head and secondly so as not to make the neck stretch further at an opposite side when it tilts.
  • the collar is provided to restrain neck tilting beyond a certain point so that excessive stretching cannot occur which may cause tearing at the nerve roots in the cervical region at the opposite side to the bags.
  • the bags 13 and 15 at least are separated from the surface of the neck, so that when the head has any tendency to overtilt sideways, the bags act to prevent the head tilting further by fitting between the tilted head and the shoulder of the wearer.
  • the bag 14 likewise prevents over tilted of the head backwards.
  • the air bags are preferably separated from the surface of the neck by about 5 cms and each have an effective overall height of about 12 cms. These dimensions are commonly suitable and represent a compromise between what might be ideal for medical safety, for example a larger height bag placed further from the neck, and what is comfortable and convenient to wear. In other words or generally stated, the wearer will normally prefer smaller air bags whereas the medical ideal is larger or higher air bags.
  • the bags 13, 14 and 15 may also comprise permanently inflated bags or bags made of resilient material, such as foam cushion material.
