A shock absorbing cap provides shock abortion in the space between the interior of a traditional safety helmet and the head of the wearer. The cap has a first region next to the scalp which is made of 100% knitted cotton for comfort and the absorption of sweat. A second region is made of 100% wool fleece braided fiber bundles that extend alternately in longitudinal and lateral directions sufficiently to nearly fill the space. The outermost region is made of one or more layers of braided 100% carbon fiber bundles, which run the opposite direction of the last wool lock. In an alternative, the first region is used but the second region completely fills the space with woven aramid and carbon fiber squares laid on top of each other and sewn together. The uppermost portion is laser cut for a tight but comfortable fit under the helmet.

A liner assembly for a protective helmet has a rigid shell with an inner surface and concave curvature having a front portion, a rear portion, a crown portion, a pair of opposite portions and a pair of opposite jaw flaps; a wrap-around pad has a plurality of circular cells spaced along a curved line around the inner surface, and at least one additional cell at each end of the curved line. Two jaw pads, each jaw pad removably engaged to a respective one of the jaw flaps, and each jaw pad has one cell having one cell with two curvilinear segments. Each cell of the wrap around pad and the jaw pads includes an outer sheet of thermoplastic and an inner sheet of thermoplastic.

A protective apparel system is provided that comprises a helmet covering the wearer's head and a gown covering the wearer's body. A protective barrier extends between the helmet and the gown in order to separate an interior space from the exterior space. The helmet may be a reusable rigid helmet with an exterior surface that can be repeatedly disinfected. The helmet may also include an air transmission system.

A protective hood (10) is provided for use by a firefighter or other emergency worker, and includes a crown portion (12), a head portion (14), a face opening (16) defined by a peripheral edge (18), and front and rear drapes (20,22). At least some of the parts (12,14,18,20,22) are formed from a knit material and at least other of the parts (12,13,18,20,22) are formed from at least one layer of woven material.

A safety helmet is disclosed having a shell and a comfort liner coupled to the inner surface of the shell. The comfort liner is constrained to the front part and to the rear part of the shell, and the helmet has a webbing arranged between the shell and the comfort liner along the upper median portion of the comfort liner. The webbing has a front end constrained to the front part of the comfort liner and a rear end to move the webbing with respect to the shell and cause consequently the change of the overall dimensions of the comfort liner inside the helmet. The webbing is constrained, with respect to the shell, in an operative position corresponding to the overall dimensions of the comfort liner inside the helmet.

A structure, e.g., a shock absorbing cap, provides additional force or shock abortion between the interior of a traditional safety helmet and the head of the wearer. As a result, there is no need to change the helmets currently in use today. The cap has a first region, which is next to the scalp and is typically made of 100% knitted cotton. A second region is typically made of 100% wool fleece braided fiber bundles or locks that extend alternately in longitudinal and lateral directions. A sufficient number of layers of the knitted cotton bundles is provided to principally fill the gap between the head of each wearer and the interior of the helmet. This layer is the main shock absorbing element. The outermost region is typically made of one or more layers of braided 100% carbon fiber bundles, which run the opposite direction of the last wool lock. This carbon fiber bundle region helps to retain the structure of the cape. Every two layers in the cap are interlocked with the other layers on either side, except that the interlocking stops with the top carbon layer.
