Disclosed is a size adaptive protective headgear including a protective shell including a first and a second front cut extending respectively from a first and second side edge of the protective shell, the first and second front cut enabling expansion and contraction of a front section of the protective shell, and a first and a second rear cut extending respectively from a first and second side edge of the protective shell, the first and second rear cut enabling expansion and contraction of a rear section of the protective shell.

A helmet for receiving the head of a hockey or lacrosse player, the helmet having an outer shell and an inner lining covering at least partially the inner surface of the outer shell. In one embodiment, the helmet comprises a skeleton at least partially covered by the inner lining, a movable occipital pad and movable temple pads. The inner lining can be made of an absorptive material such as foam, expanded polypropylene or expanded polyethylene and can be overmolded onto the skeleton. The occipital pad and the temple pads may be arranged with an inward bias so as to help the helmet self-adjust to provide an advantageous fit on the player's head. In some embodiments, the outer shell and skeleton, or the outer shell and the inner lining, cooperate to define a ventilation system.

A fit system for a helmet can include an adjuster including a width adjustment track, and first and second pods moveably coupled to the width adjustment track with a first and second support arm, the second pod comprising a lateral offset from the first pod. The fit system can further include a dial moveably coupled to the adjustor, such that movement of the dial changes a size of the lateral offset between the first pod and the second pod. The fit system can further include a hanger flexibly coupled to both the first pod and the second pod and adapted to allow for adjustment of the lateral offset between the first pod and the second pod. The hanger can further be adapted to allow for movement of the first pod and the second pod in a direction substantially perpendicular to the lateral offset without movement of the dial.

A bicycle helmet that fits over a surface of a head of a user generally includes a segment of flexible cell structures that form a radial honeycomb matrix movable between a folded condition where each side of the segment is disposed generally parallel and an expanded condition where the radial honeycomb matrix of the segment is configured to be expanded at least partially over the head of the user and arranged radially relative to the surface of the head of the user. The bicycle helmet includes a first and second side frame disposed respectively at the first and second ends of the honeycomb matrix.

A personal protection system for providing a sterile barrier around medical/surgical personnel. The system includes a helmet over which a hood or a toga suspended. The helmet has a chin bar that extends forward of the face of the individual wearing the system. At least one manually actuated control for regulating one aspect of operation of the system is mounted to the chin bar. Sometimes the control is a button that is depressed to control the operation of a helmet mounted fan that draws air into the hood or toga. A microphone may also be mounted to the chin bar.

The present invention relates to a protective helmet (1) comprising: an outer shell (10); an impact absorbing liner (12), positioned inside the outer shell (10), and a comfort liner (14), positioned at an inner surface of the impact absorbing liner (12), so as to be in contact with the user's head during the use of the protective helmet (1). The comfort liner (14) comprises at least one cheek pad (16) including a padding layer (18) and a pad back plate (20). The at least one cheek pad (16) is coupled to the impact absorbing liner (12) by means of magnetic coupling means (22, 24) provided at the interface surface (P) between the pad back plate (20) and the impact absorbing liner (12). The magnetic coupling means comprise at least one projection (22), provided with a first magnetic element (26), designed to be inserted inside at least one recessed seat (24) in proximity of which a second magnetic element (28) is arranged. According to the invention, the at least one recessed seat (24) has a different size and shape with respect to said at least one projection (22). Said at least one projection (22) is adapted to move inside said at least one recessed seat (24) between a first position, wherein the first magnetic element (26) and the second magnetic element (28) are faced to each other, and a second position, wherein the first magnetic element (26) and the second magnetic element (28) are spaced apart, so that the pad back plate (20) is releasable from the impact absorbing liner (12).

A foldable helmet is provided. The helmet includes a plurality of struts hingedly interconnected thereby enabling the struts to splay out from a closed packed state. Each strut includes a hinge along a length of the strut for folding the strut and a plurality of cutouts allowing the strut to bow in a direction opposite a fold direction of the hinge.

The invention relates to a protective helmet comprising a plurality of segments, at least two of said segments (106, 107) being connected together by way of a sliding connection for sliding purposes, said segments connected by said connection having complementary and approximately parallel indentations and protrusions, characterized in that, for each sliding connection, said protrusions of at least one of the segments are connected together by way of a transverse bar.

A helmet for protecting a head of a wearer, such as a hockey, lacrosse, football or other sports player. The helmet includes an outer shell and padding disposed between the outer shell and the wearer's head. The padding includes an inner part configured to face the wearer's head and an outer part disposed between the outer shell and the inner part. The inner part of the padding includes rotational impact protection pads that are spaced from one another and arranged so that they are oriented towards different areas of the wearer's head. Each rotational impact protection pad is separately connected to the outer part of the padding and is movable relative thereto by sliding against the outer part of the padding in response to a rotational impact on the helmet, wherein given ones of the rotational impact protection pads have different shapes and/or different sizes from one another.

A modular helmet system comprises a helmet and a chin bar detachably mountable to the helmet. The helmet comprises two receiving-brackets. The chin bar may be inserted into the receiving-brackets of the helmet with its two ends in front in a substantially straight line, wherein the chin bar is lockable in the receiving-brackets in an end position. Each of the two receiving-brackets comprises two insertion flanks which extend towards each other along the direction of insertion at an acute centering angle, wherein the insertion flanks are configured to center the chin bar in the vertical direction when being inserted and to form a stop for the chin bar in the end position of the chin bar.
