Definitions

  • This application relates to a safety helmet assembly, such as a fireman's helmet, and more particularly to an improved head band and chinstrap assembly for positioning, adjusting and securing the protective helmet assembly onto the head of the user.
  • the protective helmet assemblies are primarily dominated by head adjustment systems that are individually accomplished by each wearer/owner.
  • the most popular version of such fixed adjustment suspension system employs a post and hole, single adjustment, with the adjustment accomplished at the sides or at the rear.
  • a ratchet system and alternately a breakaway feature allow more flexibility and adjustability on a quick-release basis, should the wearer change the protective equipment he is wearing under the suspension system, and needs to change the sizing to fit the helmet properly on his head.
  • Such breakaway feature is a fixed one, however, and does not refit the helmet, but simply opens it up generally, allowing for the increase in sizing caused by donning the breathing apparatus face piece, a knit hood, or both.
  • Such ratchet system has a turning knob that mounts at the rear of the head, under the helmet and suspension system. It is exposed well outside the protective envelope of the helmet, but does provide reasonably comfortable and effective instant adjustment, no matter what kind of equipment layering is going on underneath the head suspension system in the helmet.
  • the ratchet system poses the very present danger of being exposed to direct impact, and focusing impact energies in transferring that impact to the user's head. Any adjustability feature of the ratchet system has been deemed so important with the changes in head sizing caused by donning and doffing the various new layers of protection common to the fire service, that people have decided to overlook the potential danger of "on-ratchet" impact in deference to the importance of proper fit.
  • Another object of the present invention is to provide an improved protective helmet assembly readily adjustable in one operation to the head of the user.
  • Still another object of the present invention is to provide an improved protective helmet assembly capable of facile adjustment to the head of the user regardless of head size.
  • Yet another object of the present invention is to provide an improved protective helmet assembly permitting of use exchange between users, regardless of head size.
  • a further object of the present invention to provide an improved protective helmet assembly having a readily replaceable head adjustment suspension system.
  • a still further object of the present invention is to provide an improved protective helmet assembly.
  • a protective helmet assembly including an outer impact shell and an inner impact attenuation liner assembly including an adjustable headband assembly comprised of a front headband member and a rear spring-loaded headband member under the control of a chinstrap into a fitted configuration about the head of the user by a clip assembly.
  • the inner impact attenuation liner assembly is mounted within the outer impact shell to separate therefrom under predetermined load conditions.
  • FIGURE 1 a profile view of a fireman's protective helmet assembly embodying the present invention, generally indicated as 10, comprised of an outer shell 12 in which is mounted an inner adjustable impact attenuation liner assembly, generally indicated as 14.
  • the outer shell 12 is formed with a brim 16 wider at the back than at the front to shield the back of wearer's neck.
  • a transparent visor 18 is rotatably mounted by mounting assembly (not shown) to the outer shell 12 to be lowered to provide eye protection to the user, such as illustrated in U.S. Patent No. 4,286,339 assigned to the same assignee as the present invention.
  • a chinstrap assembly, generally indicated as 20, is mounted in an adjustable manner as part of the inner liner assembly 14 as more fully hereinafter described.
  • the inner impact attenuation liner assembly 14 is positioned within the outer shell 12, referring to FIGURE 2, and is comprised of a hemi-ovoid-shaped non-resilient foam liner 24 and a cradle, generally indicated as 26, of a plurality of web straps 28.
  • the foam liner 24 of the inner liner assembly 14 is frictionally fitted within the outer shell 12.
  • the exterior surface of the foam liner 24 generally corresponds to the interior surface of the outer shell 12. Frictional retention of the foam liner 24 in the outer shell 12 is augmented by the use of cooperating patches of hook and loop fastener material, generally indicated as 30 (one shown) such as that sold under the trademark "Velcro®", reference to FIGURE 1.
  • the foam liner 24 is molded of a non-resilient foam material, such as polyurethane and is chosen to be deformable under high lateral impact conditions to distribute the force of impact over a relatively large area of the head and to adsorb energy while deforming to reduce the lateral force transmitted to the head.
  • the interior portion of the foam liner 24 is lined with a thin plastic shell 32 of a rigid plastic material including an annular rim portion 34 of channel cross-section positioned about the annular lower end of the foam liner 24.
  • Each strap 28 is formed of a strong webbing, such as nylon, stitched together at the central apex of the cradle 26 and proceeds from the apex to the rim portion 34.
  • Each strap 28 wraps about the rim portion 34 and proceeds upwardly along the outer surface of the foam liner 24, is wrapped about a tube member 36 inset in a groove 38 formed in the outer surface of the foam liner 24.
  • the loops 40 of the free ends of each of the straps 28 are collected by a drawstring 42 knotted to allow adjustment of the cradle 26 to suit the individual.
  • the helmet assembly is supported on the wearer's head by a headband assembly, generally indicated as 44, comprised of a front headband member 46, and a rear adjustable headband member 48 positioned on plate members 50 mounted, such as by pin members 52, to the inner liner assembly 14 proximate each side portion thereof.
  • the front headband member 46 is lined with a sweatband 54 and is formed with a perpendicularly-disposed and upwardly extending tab member 56 having a strip of fastening material 58 mounted on an outer surface thereof in axial alignment with a cooperating strip of fastening material 60 vertically mounted to the inner surface of shell 32 disposed within the foam liner 24 in a vertical fore and aft axis of the protective helmet assembly 10.
  • Lateral free ends 62 of the front headband portion 46 is formed with a plurality of holes 64 for adjustably positioning each free end 62 thereof on a pin member 66 formed on each plate member 50 as more fully hereinafter described.
  • the rear adjustable headband member 48 is provided with a sweatband 68 and is formed with an upwardly extending parallel-disposed leg portions 70 disposed along such vertical fore and aft axis with upper end C-shaped portions 72 thereof being mounted behind the tube member 36 above an outer portion of the rim 34.
  • Side free-end portions 74 of the rear adjustable headband member 48 are formed with a slot 76 referring more particularly to Figure 8, and are slidably mounted to the plate member 50 by a pin member 78 for lateral fore and aft movement with respect to the foam liner member 24, as more fully hereinafter described.
  • the chinstrap assembly 20, referring particularly to Figure 4 is comprised of chinstrap members 80 and 82 formed of a strong webbing material, such as NOMEX® or nylon, with an end 84 of one strap member 80 provided with an engaging clip member 86 for affixing the chinstrap member 82 having a cooperating clip member 88 into the chinstrap assembly 20 for encircling about the user's jaw for closely engaging the user's chin.
  • the chinstrap member 80 is mounted to the inner liner assembly 14, such as by the other ends 90 encircling the tube member 36 in a manner similar to the mounting of the straps 28.
  • the chinstrap member 80 is formed with an inwardly extended free-end portion 92 to act as a barrier between the cooperating affixed clip members 86 and 88, and the face of the user.
  • An end 94 of the chinstrap member 82 remote from that portion having the clip member 88 is mounted by stitching (not shown) to an outer surface portion the plate member 50 opposite the chin strap member 80 and is coursed over an outer surface portion of the rear headband member 48 and through a ring member 98 mounted to a strap member 100 and thence returning to a locking clip member, generally indicated as 102 for adjustable fixation, as more fully hereinafter described.
  • the strap member 100 is coursed through a positioning loop 104 and is mounted by a pin member 96 to the plate member 50 proximate the chinstrap member 80.
  • the clip member 102 referring more particularly to Figure 6 and 7, is comprised of a plate member 110 to which is mounted for rotation, such as by a pin member 112 a locking element 114.
  • the plate member 110 of the clip member 102 is mounted by upper end C-shaped portions 106 by the tube member 36 to the inner liner assembly member 14 in a vertically downwardly depending position essentially parallel to the longitudinal axis of the inner liner assembly member 14 referring to Figures 2 to 7.
  • the plate member 110 is formed with parallely-disposed slots 116 and 118 defining an intermediate band portion 120 therebetween and a slot 122 formed at an angle of 45° to the slots 116 and 118.
  • the strap member 82 is coursed through the slots 112, 118 and 122 respectively, starting from an inwardly approach to the slot 116 whereby the strap member 82 is thereupon disposed on an outer surface portion of the band portion 120 and thence inwardly through the slot 122 to emerge outwardly through the slot 118 and thereby to depend downwardly from the plate member 110.
  • the locking element 114 of the clip member 102 is formed with an enlarged portion 124 defining a loop 126 through which is coursed the downwardly depending strap member 82 and with a serrated section 128 proximate the channel 120.
  • the pin member 112 permits rotation of the locking element 114 with respect to the plate member 110 in a plane parallel to the axis of the pin member 112 and perpendicular to the strap member 82 passing through the slots 116 and 118, as more fully hereinafter discussed.
