A protective helmet includes an upper section and a lower section; each having inner and outer facing surfaces; a gap formed between the upper and lower sections; at least one connection member connecting the upper section to the lower section and maintaining the gap; the upper section being movable with respect to the lower section when an impact force is applied to the outside surface of the upper section; an inner shell securable to the inner facing surface of the lower section; the inner shell being adapted to receive a portion of the helmet user's head, whereby the head of the user will be spaced from the inner facing surface of the upper section when the portion of the user's head is received in the inner shell; and the inner shell substantially preventing the user's head from making contact with the inner facing surface of the upper section.

The present disclosure seeks to reduce the effects of rotational and linear acceleration experienced by the body of a user in response to an impact force. Modular disengaging systems of the present disclosure are generally suitable for coupling to protective equipment to provide a disengaging motion between various layers such that the effects of the impact force to the body of the user are reduced. Generally described, the modular disengaging systems of the present disclosure include layers configured to facilitate relative lateral motion therebetween upon an impact force.

An informatics system that can be head-worn under a helmet and used to provide a wearer's vital statistics and other information to a remote monitoring station, for example in connection with pre-hospital emergency care.

A helmet can include an energy absorbing shell including an outer surface and an inner surface opposite the outer surface. A fit system member can be coupled to a rear of the energy absorbing shell to adjust a fit of the helmet for a user. A sliding layer can include an outer sliding layer surface oriented towards the inner surface of the energy absorbing shell and an inner sliding layer surface opposite the outer surface. The sliding layer can include at least one attachment member and at least one integrated fit system arm. The at least one integrated fit system arm can be coupled to the fit system member. An elastomeric member can include a first end coupled to the energy absorbing shell and a second end coupled to the attachment member of the sliding layer. Comfort padding can be coupled to the inner surface of the Sliding layer.

A helmet can comprise an upper-body and a lower-body nested within the upper-body. An opening can be formed within a front portion of the helmet and disposed between an outer surface of the upper-body and an inner surface of the lower-body. A first magnet can be encased within the upper-body or the lower-body and adjacent the opening. A shield can comprise a shield mount and a second magnet coupled to the shield mount that is sized to fit within the opening and to be releasably coupled to the first magnet. The first magnet and the second magnet can be self-aligned in direct alignment with eyes of a user. A third magnet can be disposed above the first magnet and aligned with the second magnet on an outer surface of the helmet out of sight from eyes of the user.

A fit adjustment system for a helmet is described.

An adjustment device of the position of a first part with respect to a second part, comprising an adjustment button mounted movable in translation inside a groove provided in the second part, and a blocking part having a locked position in which the blocking part prevents the first part from translating along the groove, and a locked position in which the blocking part enables the first part to translate along the groove, the adjustment button translating along the groove to move the blocking part to the unlocked position and to translate the first part along the groove.

A head protection system includes a safety helmet and a fire protection cloth. The safety helmet includes a helmet shell (105) and a holding device (108) to guarantee a distance (A) between a helmet shell inner side (106) and the user head (102). An air path (110) is formed by a plurality of openings (120) of a fastening ring (125) and the distance between the inner side of the helmet shell and the head of the user. The fastening ring is arranged at least in an area of the user forehead of the user. The fire protection cloth has a fastening strap (230) with rigid fastening elements (235) configured to mesh with an opening of the fastening ring to detachably fasten the fire protection cloth to the safety helmet. The rigid fastening elements fill the plurality of openings in the fastened state to close the air path.

A helmet which includes an impact absorbing liner and a comfort liner. The comfort liner in turn includes at least one adjustable device which during the normal use of the helmet is positioned on the top of the head of the user. The adjustable device is suitable for being fastened to the impact absorbing liner of the helmet by coupling suitable for being removably engaged on the impact absorbing liner of the helmet via a plurality of anchor points. By changing the anchor point where the adjustable device is engaged, the user is allowed to adjust the conformation and slope of the adjustable device of the helmet according to his own needs.

The present invention provides a scalp protector for use following a hair transplant procedure conducted on a subject including: a cover having a central region and elongated portions extending from the central region for covering the surface of the scalp of the subject, each of the elongated portions provides at least one set of a first part of a snap fasteners closure; a band configured to extend around the periphery of the scalp of the subject, the band includes anchoring regions deployed on the band so as to align with the elongated portions of the cover, each of the anchoring regions providing at least one set of a complementary part of a snap fasteners closure for fastening to the elongated portions.
