The present invention provides a safety helmet inner lining adjustable for suitable wearing, consisting of: a covering body, which has an inner side surface that contacts a user's head and an outer side surface relative to the inner side surface; at least one interlayer pocket, which is disposed on the outer side surface of the covering body; and at least one cushiony pad, which is suitable for placement inside the interlayer pocket. A user is able to place the cushiony pads of suitable thickness into the interlayer pockets at preset positions according to the user's to head shape and dimensions. The inner lining is then put onto the head and a safety helmet put on top. The cushiony pads enable correcting the interspace between the user's head and the safety helmet, thereby allowing suitable and perfect fitting of the safety helmet that ensures safety of the wearer.

The present disclosure discloses an intelligent hair growth helmet, and relates to the field of medical instruments. The intelligent hair growth helmet includes a helmet outer shell; an inner housing is fixedly mounted in the helmet outer shell; a plurality of supporting pipes are uniformly and fixedly mounted on the inner housing; U-shaped supporting plates are fixedly mounted on inner walls of two sides of the inner housing; a plurality of mounting holes are formed in the two U-shaped supporting plates; the same cushion block is slidably sleeved in two mounting holes on the same side; two mounting shafts are symmetrically and fixedly mounted on the cushion block.

A helmet may include an outer liner and an inner liner disposed inward from the outer liner, the inner liner comprising an inner surface with at least one hole. A fit belt may comprise at least one pin coupled to an inner surface of the inner liner with the at least one hole mateably coupled with the at least one pin. An elastomeric strap may comprise an inner end and an outer end opposite the inner end. The outer end of the elastomeric strap may be coupled to an inner surface of the outer liner. The outer end of the elastomeric strap may comprise a recess and a fastener that extends through the recess of the outer end of the elastomeric strap to couple the elastomeric strap to the outer liner. The inner end of the elastomeric strap may be coupled to the fit belt.

A helmet harness (3200) has an outer shell (3205) and an inner shell (3210) held moveably together by a grommet (3215). The outer shell has an outer frame (3220) and a plurality of pads (3225) for protection and comfort. The inner shell has an inner frame (3250) and a plurality of pads (3255) for protection and comfort. The outer frame and the inner frame have a plurality of longitudinal and lateral ribs (3235, 3265). The ribs form a plurality of holes of voids (3237, 3267) which reduce weight and provide for ventilation. The pads cover at least a portion of the inside surfaces of the outer frame and the inner frame. The grommet allows the outer shell and the inner shell to pitch, roll, and yaw with respect to each other, but not to so freely move as to be distracting and undesirable to the user.

Articles including protective gear for a variety of sports and activities provide protection from one or both of linear and angular forces that either directly or indirectly impact the gear when it is donned. The articles include at least two layers of material that provide multimodal energy dissipation to minimize the extent of transmission of impact forces to tissue.

The disclosure provides a ballistic helmet that includes a helmet shell and a harness connected to the helmet shell. The helmet shell includes a front portion and a rear portion. The harness includes a nape pad, a tensioner disposed on the nape pad, more than one securement strap, and a tension cable. The more than one securement strap is connected to the nape pad and is configured to fasten to the rear portion of the helmet shell. The tension cable is selectively adjustable by the tensioner and is configured to fasten to the front portion of the helmet shell.

A hard hat style helmet includes a powered and filtered air intake and distribution system. The air distribution system directs filtered air into a breathing mask structured and located to cover a wearer's mouth and nose. The helmet includes wireless telecommunication features and a speaker and microphone to enable hands-free voice calling. The helmet also includes a camera for transmitting the wearer's field of view. The helmet also includes a transparent display inside the wearer's field of view and another display outside the wearer's field of view.
