DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

(9) The protective overgarment provides significantly improved impact and abrasion protection for persons engaged in various motorsport activities and other potentially hazardous sports such as mountaineering, rock climbing, and the like. However, rather than completely enclosing the torso and limbs of the wearer and thereby precluding air circulation and ventilation, the protective overgarment is structured to provide relatively large areas or passages between the various protective elements to allow relatively free air circulation about the torso and limbs of the wearer. The protective overgarment may also include protective covering for the helmet and/or boots or shoes worn by the wearer of the overgarment, or may comprise a partial covering, e.g., just for the arm(s) and/or the leg(s).

(10) FIG. 1 of the drawings provides an environmental view of a motorcyclist M wearing a first embodiment of the protective overgarment 10 while riding a motorcycle C. FIGS. 2 and 3 provide front and rear elevation views of the overgarment 10. The overgarment 10 of FIGS. 1 through 3 comprises a unitary structure. The torso, leg, and arm elements are all permanently joined and/or assembled either directly or indirectly to one another. The overgarment 10 is constructed using a plurality (i.e., two or more) of elongate, flexible, resilient or cushioned tubular elements 12, each of which has a generally circular or annular configuration to surround some portion of the body of the wearer, i.e., the torso, legs, or arms. The tubular elements 12 are substantially identical to one another, except that their lengths are adapted to fit comfortably about a given portion of the wearer's body. Substantially the same elements 12 may also be formed to fit about the helmet H and around the boots or shoes S of the wearer, as well.

(11) Additional connecting elements 14 and 16 extend generally longitudinally along portions of the torso, leg, and arm components, and serve to connect the generally circular tubular elements 12 with one another. The first connecting elements 14 are configured similar to the circular elements 12, i.e., with reasonable flexibility, but as the portions of the body over which they extend do not flex appreciably, they need not be constructed to have exceptional flexibility. The second connecting elements 16 are also formed as elongate, flexible, resilient tubular structures, but have corrugated or accordion fold external outer coverings to provide greater flexibility. These externally corrugated elements 16 are installed along the sides of various body joints and structures where some appreciable bending and flexing occurs, i.e., along the sides of each knee and along the sides of the torso. They may also be provided along the sides of each elbow joint when the arm portions of the overgarment 10 extend along the arms beyond the elbows.

(12) The lengths of the connecting elements 14 and 16 are sufficient to space the various generally circular elements 12 apart from one another. Adjacent elements 12 define relatively large ventilation passages 18 therebetween. Thus, a person wearing the protective overgarment 10 or any of its other embodiments will be provided with airflow through the large ventilation passages 18 to provide comfort in warmer weather, particularly if the person is riding an open vehicle at speed or is otherwise subjected to wind or airflow.

(13) Additional protection for the wearer is provided by relatively rigid protective plates removably installed at certain critical locations on the overgarment 10. The plates illustrated in FIGS. 1 through 3 comprise left and right knee plates 20 and 22, a chest protective plate 24, and left and right shoulder plates 26 and 28. Additional plates may be provided for other areas of the body, e.g., elbow plates, etc. The various plates 20 through 28 may be formed with a rigid, hard exterior shell of stiff leather, glass fiber composite, hard plastic, or other suitable material. The interior surface of each plate, i.e., the surface in contact with the conventional apparel of the wearer, is preferably formed of substantially the same material as the various tubular circular and connecting elements 12 through 16. The plates 20 through 28 are removably attached to the appropriate areas of the protective overgarment 10 by conventional means, e.g., hooks and eyes, etc. Additional spinal protection may be provided by an elongate spinal protection plate 30 having substantially the same construction as the other plates 20 through 28.

(14) FIG. 4 provides a front elevation view of an alternative embodiment of the protective overgarment, designated as protective overgarment 110. The overgarment 110 is constructed in essentially the same manner as the overgarment 10 of FIGS. 1 through 3, i.e., having generally circular tubular elements 12 and connecting elements 14 and 16 defining ventilation passages 18, and various protective plates 20 through 30. However, the protective overgarment 110 is formed in two separate sections or pieces, having a lower section or piece 112 that covers both legs and extends to approximately the waist when worn, and an upper section or piece 114 that covers the torso and arms when worn. The two sections or pieces 112 and 114 may be connected to one another by using conventional connectors, e.g., hooks and eyes, mating hook and loop fabric material, etc.

(15) FIGS. 5 and 6 provide cross-sectional views through two different embodiments of the tubular and connecting elements. The two embodiments differ from one another only in the material used to fill the central or middle layer. Each is formed of an outer layer or sheet 32 of an elastomer material, such as natural or synthetic rubber. The outer surface can be textured, e.g., including small protrusions or bumps 34 to provide better texture for the material. The middle or central layer 36 comprises a closed cover of flexible material defining an interior volume 38. The closed cover of the central layer 36 is preferably formed of a substantially gas-impervious material, such as plastic sheet or the like, particularly for the embodiment of FIG. 5. The two element embodiments shown in FIGS. 5 and 6 differ only in the material used to fill this interior volume. The embodiment of FIG. 5 is inflated pneumatically by air or other gas, and the embodiment of FIG. 6 is filled with a foam plastic material 40 or the like. The inner layer 42, i.e., the layer in contact with the conventional apparel of the wearer of the overgarment, comprises a cover of stretch fabric material (e.g., cotton knit, etc.) filled with a soft, resilient foam core material 44 in its core. The various layers may be bonded or otherwise permanently attached to one another to form the completed tubular and connecting elements.

(16) The somewhat flattened cross sections of the tubular and connecting elements shown in FIGS. 5 and 6 are exemplary. This construction may be used, or taller and narrower layers may be assembled to form elements having substantially the same height and width. The cross-sectional shapes of the layers may be adjusted to form elements having circular cross sections, generally as shown in FIGS. 2 through 4, when the layers are assembled. Other cross-sectional shapes may be developed according to the cross-sectional shapes of the individual layers. Regardless of the specific cross-sectional shape and materials of the various tubular circular and connecting elements, the additional protection and comfort provided by the protective overgarment will be greatly appreciated by those who engage in various motorsports and/or other extreme sports.

(17) FIG. 7 of the drawings provides an elevation view in section of another alternative construction for the tubular structure of the protective overgarment. The detail of the tubular structure embodiment illustrated in FIG. 7 includes an outer layer or sheet 32 of an elastomer material, such as natural or synthetic rubber. The outer surface can be textured, e.g., including a large number of small spikes 35 of resilient material extending therefrom. It will be seen that these spikes 35 could be incorporated with the embodiments of FIGS. 5 and/or 6 in lieu of the shorter resilient bumps or protrusions 34 described further above, or those resilient bumps or protrusions 34 may be incorporated with the protective structure illustrated in FIG. 7. The second layer 37 below the outermost layer 32 comprises a closed cover of flexible material defining an interior volume 39. The closed cover of the second layer 37 is preferably formed of a substantially gas-impervious material, such as plastic sheet or the like, particularly for the embodiment of FIG. 7. The embodiment of FIG. 7 may be inflated pneumatically by air or other gas as in the embodiment of FIG. 5, or may be filled with a foam plastic material or the like, as in the embodiment of FIG. 6.

(18) Proceeding from the outermost layer toward the innermost layer, the next layer 41 is also a hollow volume defined by the impervious cover 37 and a third layer or ply 43 of foam material essentially identical to the foam material 44 used in the embodiments of FIGS. 5 and 6. This hollow layer 41 incorporates a number of conically tapered coiled springs 45 captured between the layer or ply 43 and the overlying layer or ply 37. While only a single spring is illustrated in the enlarged detail view of FIG. 7, it will be understood that extension of this illustrated structure to either side of that shown in FIG. 7 will present substantially the same continuing structure. The springs 45 may be formed of a corrosion-resistant material, such as plastic, or a corrosion-resistant metal (e.g., stainless steel, etc.). The springs 45, in combination with the resilient pneumatic volume 39 thereabove, the resilient foam material 43 therebelow, and the resilient spikes or protrusions 35, provide an extremely resilient composite structure to absorb impact forces. The bottom or inner surface of the foam layer 43 is preferably covered with a layer of soft cotton fabric material 47, which is in contact with the skin or underlying clothing of the wearer when the protective overgarment is being worn. As in the case of the other embodiments described further above, the various layers may be bonded or otherwise permanently attached to one another to form the completed tubular and connecting elements. Thus, the embodiment of FIG. 7 may be arranged to include a plurality of layers comprising (1) the outer spikes 35, (2) the spike supporting layer 32, (3) the resilient pneumatic volume or layer 39, (4) the hollow layer 41 with its spring (or other resilient means) 45, (5) the layer or ply supporting the springs 45, and (6) the innermost layer 47 of soft material. These various layers (1) through (6) may be combined or deleted as desired.

(19) It is to be understood that the present invention is not limited to the embodiments described above, but encompasses any and all embodiments within the scope of the following claims.
