Abstract
Abstract A user-worn protective body appliance to prevent injury to the underlying region of the wearer's body includes a relatively rigid shield and a relatively flexible, compressible pad. The pad has a first surface to which the rigid shield is attached, and a second surface against which the body region to be protected is to be placed. The rigid shield is generally dome-shaped with such curvature as to force the relatively flexible pad, upon its attachment thereto, to assume a contour approximating that of the body region to be protected. An appropriate adhesive is applied to a limited, central portion on the second surface for securing the appliance to the body region of the wearer. In contrast, the opposite end portions on the second surface do not contain any adhesive. Consequently, when the appliance is secured to the wearer, the opposite end portions are capable of a limited degree of rocking movement in response to body movements and external forces, avoiding discomfort due to pulling of the skin at the ends of the pads and adding greatly to the comfort of the appliance, particularly during prolonged use.

Claims Analysis
Total Claims: 21
Claim 1
Independent Claim
146 words
A protective body appliance to be adhered to a body region to be protected, comprising: a pad made of a relatively flexible and relatively compressible material having a first surface and a second surface, said second surface having a central portion which contains means for adhering said pad to the body region and having two opposite end portions which are free from said means for adhering; and, a relatively rigid shield having a curved shape secured to said first surface in such a manner so that said pad assumes a contour approximating that of the body region; whereby the appliance, when adhered to the body region, is permitted a limited degree of rocking movement relative to the body region underlying said opposite end portions of said second surface and whereby said shield transfers external forces exerted upon said shield to areas spaced from said central portion.
Claim 2
Dependent Claim
146 words
A protective body appliance to be adhered to a body region to be protected, comprising: a pad made of a relatively flexible and relatively compressible material having a first surface and a second surface, said second surface having a central portion which contains means for adhering said pad to the body region and having two opposite end portions which are free from said means for adhering; and, a relatively rigid shield having a curved shape secured to said first surface in such a manner so that said pad assumes a contour approximating that of the body region; whereby the appliance, when adhered to the body region, is permitted a limited degree of rocking movement relative to the body region underlying said opposite end portions of said second surface and whereby said shield transfers external forces exerted upon said shield to areas spaced from said central portion.
Claim 3
Dependent Claim
35 words
The protective body appliance as described in claim 1 wherein said shield is secured to said first surface in such a manner so that a central portion of said shield is raised above said pad.
