US Patent 7861318 Pad wearable over articulated joint

A pad, such as a knee, elbow, or shoulder pad, is wearable over an articulatable joint involving an arm of a wearer or a leg of a wearer and is constructed so as to define two flexing lines extending between an upper edge of the pad and a lower edge of the pad, which flexing lines define a central region of the pad and two lateral regions of the pad, so as to define a flexing line spaced from the central region and extending through each of the lateral regions, and so as to define plural flexing lines spaced from the upper and lower edges and from one another and extending across the central region, between the lateral regions. The pad comprises plural layers, which are sewn so as to define the flexing lines, and at least some of those layers are fabric layers.
