Anti-abrasion protective device

Claim 2

A directionally oriented abrasion prevention device in the form of a support member worn by a user for protecting a selected portion of the user's body from excessive frictional heat and abrasion caused by specific directional sliding contact with an abrading surface during physical activity, said support member comprising: a base layer of stretch fabric positioned adjacent to the user's body, a plurality of elongated strips of a longitudinally distortable cushioning material fixably secured along their length to said base layer and covering said selected body portion, said strips being positioned substantially parallel in side-by-side relation specifically oriented on said base layer so as to longitudinally extend in the direction of purposeful and anticipated relative sliding motion between the abrading surface and the selection portion of the user's body, said strips being elastically yieldable in the direction of said purposeful relative sliding motion to absorb friction generated heat during said sliding motion, said base layer remaining substantially in position adjacent the user's body to protect the user's body from abrasion thereby preventing injury to said user, a cover layer over said elongated strips and means for attaching said cover layer to said base layer around said elongated strips, said cover layer being slidable relative said strips and said base layer to absorb a limited amount of frictional energy.

Claim 3

The device according to claim 1 wherein said support member is a pair of undergarment trousers having leg portions and a seat portion, said strips being interconnected and positioned to cover said seat portion and extending vertically toward said leg portions whereby when said user slides forwardly on said seat portion on said abrading surface, said orientation of said strips allowing said strips to yield in the direction of the sliding motion to absorb friction energy and allow said base layer to remain substantially in position to thereby prevent burns and abrasion of the user's body.

Claim 4

An abrasion prevention device in the form of a pair of undergarment trousers worn by a user for protecting a selected portion of the user's body from excessive frictional heat and abrasion caused by sliding contact with an abrading surface during physical activity, said undergarment trousers comprising: a base layer of stretch fabric adjacent to the user's body having leg portions and a seat portion, a plurality of elongated strips of cushioning material secured to said base layer covering said selected body portion, said strips being oriented on said base layer so as to extend lengthwise in the direction of anticipated relative sliding motion between the abrading surface and the selected portion of the user's body, said strips being positioned to cover said seat portion and extending vertically toward said leg portions whereby when said user slides forwardly on said seat portion on said abrading surface, said strips being elastically yieldable in the direction of the sliding motion to absorb friction energy and thereby prevent burns and abrasion of the user's body, the front of each of said leg portions covering the knee of the user and the user's shin immediately below the knee, strips of said cushioning material being secured to said leg portions covering said knee and oriented in a direction lengthwise of the leg and strips of said cushioning material being secured to said leg portions covering said shin and oriented perpendicularly to said strips covering said knee whereby when the user slides with the lower leg knee bent, said strips covering said shin yield elastically in the direction of said sliding motion of said shin.

Claim 5

An abrasion prevention device in the form of a pair of undergarment trousers worn by a user for protecting a selected portion of the user's body from excessive frictional heat and abrasion caused by sliding contact with an abrading surface during physical activity, said undergarment trousers comprising: a base layer of stretch fabric adjacent to the user's body having leg portions and a seat portion, a plurality of elongated strips of cushioning material secured to said base layer covering said selected body portion, said strips being oriented on said base layer so as to extend lengthwise in the direction of anticipated relative sliding motion between the abrading surface and the selected portion of the user's body, said strips being positioned to cover said seat portion and extending vertically toward said leg portions whereby when said user slides forwardly on said seat portion on said abrading surface, said strips being elastically yieldable in the direction of the sliding motion to absorb friction energy and thereby prevent burns and abrasion of the user's body, the front of each of said leg portions covering the knee of the user and the user's shin immediately below the knee, strips of said cushioning material being secured to said leg portions covering said knee and oriented in a direction lengthwise of the leg and strips of said cushioning material being secured to said leg portions covering said shin and oriented perpendicularly to said strips covering said knee whereby when the user slides with the lower leg knee bent, said strips covering said shin yield elastically in the direction of said sliding motion of said shin.
