Description

~329~48 Background of the Invention Field of the Invention The present inYentiOn relates to a protector and an article of sportswear using the same and more particularly but not exclusively relates to a protecting pad which is adapted to be mounted to an article of sportswear and an article of sportswear having such a protecting pad attached thereto.
Prior Art Usually, protectors are put on bodies of athletes in various hard sports, such as skiing, baseball and motorcycling, for effectively protecting them from une~pected impact. Conventional protectors include, for example, a one-piece synthetic resin protector, a protector pad, inserted in pants cloth, such as a knee pad of ski pants, an inner protector, such as used by baseball umpires, and a shinguard used by a catcher.
However, conventional protectors are disadvantageous in that provision of flexibility to them for fully following various movements of a body of the wearer rather deteriorates rigidity thereof. The rigidity or hardness of the protectors i5 required for protecting the wearer against damages due to external excessive impact.
Thus, conventional protectors do not fully meet these conflicting requirements. The prior art covers protectors ~\

~3~9~4~

I over an article of sportswear and fails ~o provide an integral type of protecting garment, in w~.ich protectors and the garment are integrally formed, except ski pants having knee pads of a flexible plastic plate incorporated into them. The knee pads of the ski pants are poor in rigidity for fitting the body of the wearer and hence they are not sufficient as protectors for hard sports.
Accordingly, it is an object of the present invention to provide a protector and an article of sportswear using the protector. The protector has sufficient rigidity against damage from external impact with light weight as compared to the prior art protector whereas it has sufficient flexibility to follow movements of the body of the wearer, thus fitting the latter.
Summary of the Invention With this and other objects in view, one aspect of the present invention is directed to a protector comprising a cushioning pad for buffering external i~pact, the cushioning pad having an inner face adapted to be mounted over a garment and a plurality of spaced substantially parallel, rigid formations mounted on the outer face of the cushioning pad to protect the cushioning pad from being damaged by external impact, characterized in that said cushioning pad comprises a plurality of closed elongate air cushion chambers therein.
hnother aspect of the present inYention is directed to an article of sportswear having the protector above defined mounted ~hereon.

Detailed ~escription of the Preferred Embodiments Referring to the drawings, like reference characters designate corresponding parts throughout views and description thereof is omitted after once given.
Referring to FIGS. 1 and 2, the reference numeral indicates an article oE skiwear for contests. The garment 1 has a plurality of protectors or protecting pads jointed on its ~houlders la, la, chest lb, elbows lc, lc, west ld, legs le, le, back lg and front portions of ankles lg, lg and wrists lh, lh, and the protecting pads 2 are mounted to optimum positions of the garment according to the kind of sport. As illustrated in FIGS. 3 and 4, each protecting pad 2 includes a cushioning sheet 5 for resiliently cushioning external impact applied to it, and a plurality of rigid ribs 3 jointed to the upper face of the cushioning sheet 5 to be substantially parallel to each other with equal intervals. In this embodiment, the cushioning sheet 5 is corrugated, and rigid ribs 3 are bonded to respective tops 51 of the sheet 5 as shown in FIG. 4. The cushioning sheet 5 and the rigid ribs 3 may be integrally jointed by heating them. Preferably~ the rigid ribs 3 are madP of a rigid vinyl chloride resin. The cushioning sheet 5 is preferably made of a soft ~inyl chloride resin, ABS

.. . . .

' ~ ; ' ' i 13~4~8 I resin, urethane resin, nylon resin, and silicon resin.
The protecting pads 2 -thus prepared may be sewn to respective parts oÆ the garment 1 by a sewin~ machine or may be attached to them through adhesive tapes. The parts la~lh of the garment 1 are selected according to the kind of the sportswear. It is preferable to attach protecting pads 2 to the garment 1 at portions where external impact is liable to be applied and where bending and stretching thereof occur freque~tly in use. The protecting pads 2 are attached to the garment 1 so that each rigid rib 3 extends transversely a general bending plane, a plane 20 for a shoulder la in FIG. 1 for example, although the plane 20 is shown by a line, which is placed on it, for illustration purpose. ~he cushioning sheet 5 has a groove 7 formed in its upper surface at the periphery as shown in FIGS. 3 and 5. The cushioning sheet 5 is sewn along the groove 7, so that stitches are received within the groove 7. Thus, the groove 7 provides a good appearance to the cushioning sheet 5 and protects the sewn thread.
As illustrated in FIG. 6, the cushionins sheet 5 may be jointed to the garment 1 by heat boncling under pressure with an adhesive and further it may be sewn to it. With such a garment 1, the user may put the protecting pads 2 on by merely wearing the garment, and may be fully protected since the protecting ~ads 2 are mounted to optimum portions of the garment 1 according to the kind of sport~
In use, protecting pads 2 are de~ormed by bending only . . . .

1 cushioni~g sheets 5 to follow ~o~ement of the body of the wearer. This is smoothly performed since the ri~id ribs 3 are arranged across respective general bendin~ planes 20 Rigid ribs 3 are subjected to ~ost external impact and protect the garment 1 from being dama~ed, and cushioning sheet 5 buffer ext~rnal impact applied to associated rigid ribs 3.
A modified form of the protecting pads 2 of FIGS. 3 and 4 is illustrated in FIG. 7, in which a resilient pad 10 is bonded to the lower face of each cushioning sheet 5. The resilient pad 10 is made of a material, such as a silicone, which does not give nay adverse effect on the skin of the wearer. When the cushioning sheet 5 is subjected to excessive e~ternal impact, the resilient pad 10 effectively absorbs the impact energy.
Still another modified form of the protecting pad 2 in FIGS. 3 and 4 is shown in FIG. 8, in which a resilient sheet 11 is bonded to the inner face 5B of the cushioning sheet 5 at the bottom 52 of the latter to define closed parallel air cushion chambers 12A, 12A, 12A,........ between the cushioning sheet 5 and the resilient sheet 11. Opposite ends 54, 54 of each air cushion chamber 12A are closed although only one end is shown in FIG. 8. With such air cushion chamhers 12A, air in the chambers buffer external impact applied to rigid ribs 3, so that an excellent cushion effect is giYen to the protector. ~nother modified form of the protecting .

-1329~8 1 pad 2 of FIGS. 3 and 4 is illustrated in FIG. 9, in which another corrugated cushioning sheet 5 is bonded to the inner face 5B of the corrugated cushioning sheet 5, to whi.ch rigid ribs 3 are mounted at respective bottoms 52, so that corresponding bottoms 52, 52 of both the cushioning sheets 5, 5 are jointed for defini~g sealed parallel air cushion chambers by opposingly facing corresponding tops 51 thereof to each other. Also, this modified protecting pad provides an improvement in cushioning effect of the pad in FIGS. 3 and 4.
FIG. 10 also illustrat~s a modified form of the protecting pad in FIGS. 3 and 4. In this modification, adjacent parallel closed air cushion tubes 13, 13, 13, made of a resilient material such as a rubber, are bonded to each other to form pairs of air cushion tubes 13A, 13A, .... and each pair 13A is bonded to the inner face 5B
of a csrresponding bottom 52 of the cushioning sheet 5, thereby forming a cushion ch~mber 12A. The air cushion tubes 13 each define an additional air cushion chamber 14. Thus, in this modified protecting pad there is provided double cushion chambers 12A, 14.
Another embodiment of the present invention is illustrated in FIG. 11, in which the cushioning sheet 5 of the protecting pad in FIGS. 3 and 4 is replaced by a plurality of parallel closed air cushion tubes 55 bonded to adjacent air cushion tubes 55. Rigid ribs 3, 3,....... are bonded to tops of respective air cushion tubes 55 to :: : . . .
