There is provided a shock-absorbing assembly engageable with a human body part, such as a human head, to protect same. The shock-absorbing assembly comprises a shock-absorbing core including an inner surface configured to face at least a portion of the human body part; and a body contact seat assembly comprising: a plurality of spaced-apart resilient posts mounted to the shock-absorbing core, each one of the resilient posts having a portion protruding from the inner surface of the shock-absorbing core; and a body contact seat mounted to the shock-absorbing core via the protruding portions of the plurality of resilient posts, so that the body contact seat is in spaced relationship with the inner surface of the shock-absorbing core and at least one of slidable, displaceable, shearable and twistable with respect to the inner surface thereof. There is also provided a helmet including such a shock-absorbing assembly and a shock-absorbing kit.

Aspects herein are directed to systems, methods, and articles for producing a patterned film and using the patterned film to form a pattern of discrete overlay film structures on a substrate material. A uniform thickness of a film material is deposited on to a first surface of a run of carrier sheets, where each carrier sheet includes one or more holes extending there through. A first carrier sheet is extracted from the run of carrier sheets, and a second surface of the carrier sheet is positioned on a substrate material. Heat and/or pressure is applied to the film material to cause the film material to transfer to the substrate material through the one or more holes in the carrier sheet forming a pattern of discrete overlay film structures on the substrate material. The carrier sheet along with remaining portions of the film material is removed from the substrate material.
