A helmet comprising an energy absorbing layer (2) and a sliding facilitator (5) is provided The sliding facilitator is provided inside of the energy absorbing (2). A method of manufacturing a helmet comprising a sliding facilitator is farther provided The method comprising the steps of providing an energy absorbing layer in the mould, and providing a sliding facilitator for contacting the energy absorbing layer.

A cycling helmet includes an outer shell and a closed cell foam layer adjacent to the outer shell. The cycling helmet also includes an inner liner adjacent to the closed cell foam layer. The cycling helmet further includes an insert of energy absorbing material adjacent to the inner liner. The insert is configured to move in multiple directions in response to an impact to the cycling helmet.

A helmet with an inner liner and an outer liner that slidably move in relation to each other. At least one flexible connector is positioned at the ovoid surface between the inner and outer liner that directly connects at least three of a plurality of liner ribs of the first liner segment to the second liner segment across a gap at a center portion of a second liner segment and at left and right sides of the second liner segment. The at least one flexible connector is in-molded with the first and second liner segments so that they move relative to each other when the inner liner slidably moves in relation to the outer liner by flexing the at least one flexible connector. Elastomeric anchors coupled to the outer liner and to the at least one flexible connector may be included, and a fit system may be used.

A connector (50) for connecting an inner shell (3) and an outer shell (2) of a helmet (1) so as to allow the inner shell and the outer shell to slide relative to each other, the connector (50) comprising: a first attachment part (51) for attaching to one of the inner shell and the outer shell; a second attachment part (52) for attaching to the other of the inner shell and the outer shell; and one or more resilient structures (53) extending between the first attachment part and the second attachment part and configured to connect the first attachment part and the second attachment part so as to allow the first attachment part to move relative to the second attachment part as the resilient structures deform; wherein the resilient structures comprise at least one angular portion between the first attachment part and the second attachment part, an angle of said angular portion being configured to change to allow relative movement between the first attachment part and the second attachment part.

A cycling helmet includes an outer shell and a closed cell foam layer adjacent to the outer shell. The cycling helmet also includes an inner liner adjacent to the closed cell foam layer. The cycling helmet further includes an insert of energy absorbing material adjacent to the inner liner. The insert is configured to move in multiple directions in response to an impact to the cycling helmet.

A helmet may include an upper-body comprising a first outer shell coupled to a first energy-absorbing shell formed of expanded polypropylene (EPP), expanded polystyrene (EPS), expanded polyurethane (EPU), or expanded polyolefin (EPO). A lower-body may include a second outer shell coupled to a second energy-absorbing shell formed of EPP, EPS, EPU, or EPO, wherein an upper portion of the lower-body is nested within the upper-body and a lower portion of the lower-body extends to an outer surface of a lower portion of the upper-body. A strap anchor may be disposed between the upper-body and the lower-body, and be sandwiched between the upper-body and the lower-body with the strap anchor being adjacent to, and oriented towards, the lower-body. A strap may be coupled to the fastening device and coupled to the strap anchor for coupling the helmet to a head of a user.

A helmet having an energy absorbing layer and a sliding facilitator is provided. The sliding facilitator is provided inside of the energy absorbing layer. A method of manufacturing a helmet having a sliding facilitator is further provided. The method includes the steps of providing an energy absorbing layer in a mold, and providing a sliding facilitator contacting the energy absorbing layer.
