An article of apparel for a human being, designed or arranged to be worn around an appendage such as an arm or leg, and designed or intended to resist impact. The article contains a material in the form of a spongy, elastic polymer engineered to absorb energy, shock, vibration and impact. The article of apparel can be used to protect hard, bony areas of the human body such as elbows, knees and ankles. The article will be of use to persons engaged in sports involving bats, sticks, mallets, pucks and hard balls, as well as to cyclists, and anyone whose occupation requires the knees or elbows to come into contact with hard surfaces. |

1. An article arranged to be worn by a human being as protection of a region of the body other than the skull, hands and feet vulnerable to injury from mechanical shock, vibration or impact, said article comprising:
(a) at least one releasably attachable pad arranged to contact an area of the body; (b) said pad comprising a laminate having sufficient length and width to essentially completely cover a zone of the area to be protected, said laminate comprising (i) at least one layer of a soft fabric arranged to contact the body, (ii) at least one fabric selected from the group consisting of canvas and duck cloth, and (iii) an energy/shock/vibration/impact (ESVI)-absorbing material located between said at least one soft fabric and said at least one fabric; and (c) a means for temporarily attaching said laminate to the body of the human being; and (d) wherein said ESVI-absorbing material (i) is non-porous and (ii) comprises a polyurethane elastomer that is a reaction product of a compound containing at least four urethane-forming reaction sites that are capable of forming stable complexes through unsatisfied urethane-forming reactive sites, an elasticizing polyol, and a diisocyanate added in less than a stoichiometric amount. |
