Definitions

  • the present invention relates to safety helmets, and more particularly to a safety helmet that absorbs impact from multiple directions.
  • incoming impact can be divided into three types, namely radial impact, tangential impact, and diagonal impact. Radial impact can cause linear acceleration of a user's head that may lead to skull fracture and/or traumatic brain injury. Tangential impact can cause angular acceleration of a user's head that may bring about shear-based injury to brain and/or cervical vertebra.
  • US 2017347736 discloses a helmet that includes an energy absorbing shell including an outer surface and an inner surface opposite the outer surface.
  • a fit system member can be coupled to a rear of the energy absorbing shell to adjust a fit of the helmet for a user.
  • a sliding layer can include an outer sliding layer surface oriented towards the inner surface of the energy absorbing shell and an inner sliding layer surface opposite the outer surface. The sliding layer can include at least one attachment member and at least one integrated fit system arm.
  • the at least one integrated fit system arm can be coupled to the fit system member.
  • An elastomeric member can include a first end coupled to the energy absorbing shell and a second end coupled to the attachment member of the sliding layer.
  • WO2018107286 A1 discloses a cushion for use in a helmet comprising an outer shell for impact with an incoming force, the cushion disposed between the outer shell and a head when the helmet is worn, the cushion comprising: a sealed bladder comprising a flexible membrane; a pad housed within the bladder, comprising a compressible member having interstices open to the exterior of the pad; and a liquid within the interior of the bladder.
  • the pad absorbs at least some of said liquid when uncompressed and expels said liquid when compressed.
  • the volume of liquid is sufficient to allow opposing surfaces of the bladder to be displaced in a shearing motion when the cushion is subjected to shear forces.
  • the primary objective of the present invention is to provide a safety helmet that absorbs multi-direction and thereby provides improved protection to its user's head.
  • the disclosed safety helmet comprises a shell, a flexible frame, and a slide-facilitating member.
  • the flexible frame is attached to the inner surface of the shell, and the slide-facilitating member is attached to the inner surface of the flexible frame.
  • the flexible frame supports the shell, while retaining the slide-facilitating member, so that the slide-facilitating member can fittingly and comfortably embrace a user's head.
  • the slide-facilitating member facilitates slide of the shell.
  • the slide-facilitating member has a covering and a slide-facilitating medium, in which the covering is attached to the inner surface of the flexible frame and the slide-facilitating medium is wrapped by the covering.
  • the slide-facilitating medium has a substrate and a plurality of flexible bars connected to the substrates.
  • the flexible bars have deforming property that allows such slide. In this way, the impact force otherwise acting on the user's head can be absorbed and converted into other forms of energy, thereby providing better protection to the user's head.
  • the slide-facilitating medium may be realized in various aspects.
  • a safety helmet 10 of the present invention comprises a shell 20, a flexible frame 30, and a slide-facilitating member 40.
  • the shell 20 has a casing 21 and a buffer layer 22.
  • the buffer layer 22 is adhered to the inner surface of the casing 21 using an adhesive.
  • the casing 21 is made of a rigid material, such as hard plastic, and serves to provide first-line protection.
  • the buffer layer 22 is made of a shock-absorbing material, such as foam, for damping shock and buffering.
  • the flexible frame 30 is made of an elastic material, such as elastic plastic. As shown in FIG. 2 , the flexible frame 30 has two symmetrical top ribs 32 and a side rib 34.
  • the two top ribs 32 each have one end integratedly connected to the front end of the side rib 34, and the rear end of the side rib 34 is provided with an adjuster 36, which can be used to adjust the circumference of the side rib 34 so that the side rib 34 can fittingly wrap different sizes of users' heads.
  • the top ribs 32 and the side rib 34 are each detachably attached to the inner surface of the buffer layer 22 of the shell 20 inner surface through a fastener (not shown) such as a VelcroTM tape.
  • a fastener not shown
  • the top ribs 32 and the side rib 34 may each have its outer surface provided with a plurality of tenons 38, so that in addition to the adhesion of the fasteners to the inner surface of the buffer layer 22 of the shell 20, these tenons 38 can engage with mortises 23 correspondingly arranged on the buffer layer 22 to enhance the combination between the flexible frame 30 and the shell 20 while allowing easy detachment of the flexible frame 30 for convenient adjustment.
  • the slide-facilitating member 40 has a covering 41, which is made of a low-friction material, such as flannel.
  • the covering 41 has one side adhered to the inner surface of the flexible frame 30 through fasteners (not shown) such as velcro tapes, so that the slide-facilitating member 40 can be retained by the flexible frame 30 to have the reverse side of the covering 41 contact a user's head 12 directly. In this way, the covering 41 can be easily detached for convenient cleaning when staining.
  • the slide-facilitating member 40 further has a slide-facilitating medium 42 wrapped by the covering 41. As shown in FIG.
  • the slide-facilitating medium 42 has a substrate 60 and a plurality of flexible bars 62 connected to the substrate 60, so that the elasticity of the flexible bars 62 allows the shell 20 to slideIt is to be also noted that, the slide-facilitating member 40 shown in FIG. 2 contains two units, one corresponding to head top and the other embracing the head peripherally. However, in practice, the two units may be integrated into a unity, or alternatively be divided into three or more units, depending on practical needs.
  • the slide-facilitating member 40 when the shell 20 is subject to incoming impact, the casing 21 of the shell 20 bears part of the energy, and the buffer layer 22 of the shell 20 absorbs a part of energy. Then when the remaining energy is transmitted to the slide-facilitating member 40, as shown in FIGs. 3 and 4 , the slide-facilitating member 40 has the slide-facilitating medium 42 allow the shell 20 to slide with respect to the head 12, so that the impact force reaching the slide-facilitating member 40 is converted into potential energy generated by the relative displacement. The slide-facilitating member 40 can even slide with respect to the head 12 due to the low friction of the covering 41, so that the impact force reaching the slide-facilitating member 40 can be further converted into thermal energy generated by mutual friction.
  • the disclosed safety helmet 10 when the disclosed safety helmet 10 is subject to incoming impact, it uses the deformation of the shell 20 itself, the relative slide between the shell 20 and the head 12, and the friction between the covering 41 and the head 12 to multiply absorb and convert the impact force otherwise directly acting on the head 12 into other forms of energy, so as to reliably protect the head 12 from impact coming in multiple directions, especially diagonal impact.
  • slide-facilitating medium 42 may be embodied in various forms.
