Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
121 words
A protector for an articulated body joint comprising: a plurality of complementary protector elements having each: an underlay; a covering layer of a yieldable material; and a shock-absorbing segment arranged between the underlay and the covering layer; grooves having a wedge-shaped cross-section and separating the protector elements form each other, the protector elements being connected with each other along bottom surfaces of the wedge-shaped grooves; wherein some of the protector elements have complementary outer edges spaced from each other and defining empty spaces between respective protector elements, which empty spaces have a substantially triangular shape such that the empty spaces disappear on bending the protector and permit the protector to adopt a spheroidal shape corresponding to the protectable articulated body joint.
Claim 2
Dependent Claim
