A head piece (10) adapted to be worn with and without earmuffs (16), which head piece (10) includes ear portions (11) adapted to cover the ears of a person wearing the head piece (10). The ear portions (11) include at least one cover piece (12,12′12a,12b) that may be placed in an open mode in which it allows access of an earmuff (16) through the ear portions (11) of the head piece, wherein the cover piece (12,12′12a,12b) when in an closed mode covers the ear portion so as to keep the ears of a person wearing the head piece (10) covered.

A swimming cap which prevents water from entering ears has a swimming cap main body; the swimming cap main body has a left side and a right side, each of which is symmetrically provided with an ear enclosing part for accommodating a human ear; each of the ear enclosing parts has an outer wall which protrudes outwards from an outer wall of the swimming cap main body; each of the ear enclosing parts has an inner wall which forms an enclosing space for enclosing the human ear which protrudes outwards from an inner wall of the swimming cap main body; each of the enclosing spaces has an outer edge which is provided with a waterproof edge in shape of an inclined trumpet at a connecting portion with the swimming cap main body. The present invention is simple and compact in structure and highly practical.

Earmuffs with a joint are provided to create a biased pressure distribution about a perimeter of the cup. The earmuffs may include a pivot joint. The pressure distribution creates a wedging pressure (e.g., on a top edge) on the cups that hold the earmuffs on the user's head, for example, when the user rotates the headband behind the head. The bias pressure is also used to adjust the seal formed between the pad and the user's head. Adjustments to the moment created by separating the joints from the cup's apex enable a user to selectively adjust the seal according to the user's preference. A cam is added to the headband to change the hoop stress distributed at the joints and further adjust the compressive forces generated to hold the earmuffs against the user's head.

A sound-attenuating assembly may have a headpiece and two covered dampening assembly that may be detachably attached to the locations of the headpiece that oppose a wearer's ear; the dampening assembly may have a padded member member that may be in contact with a dividing member that may be in a contact with a compressible member which may be disposed within a concave member; the dampening assembly may be disposed within a cover such a fastener of the cover detachably attaches to a fastener of the headpiece.

The present invention is directed to earmuffs, and is intended to allow for hot packs to be used, thereby improving the effect of protecting ear regions from cold and a cold wave in the winter season. In order to achieve this, the present invention provides earmuffs (10) including a pair of ear covers (11) and a band (12) configured to connect the ear covers (11), wherein reception slots (13) through which hot packs (20) configured to generate heat are inserted and stored are formed in the ear covers (11), respectively.

A replaceable earmuff system with an arch-shaped member (headband) and first and second earmuff assemblies that are removably attached to the arch-shaped member. Each earmuff assembly has inner and outer earmuff housings and a spring. The inner earmuff housing is circular in shape with a flat base plate and a lip that extends around the perimeter of a first side of the inner earmuff housing. A circular protrusion, which has two opposing L-shaped slots, is situated in the center of the inner earmuff housing on a second side of the inner earmuff housing. The outer earmuff housing is saucer-shaped with a concave inner side and a convex outer side. A circular collar with two opposing keys that fit within the L-shaped slots is situated in the center of the concave inner side of the outer earmuff housing. The spring fits within the circular protrusion and the circular collar.

A visor carrier assembly for a safety helmet includes a double-pivot mechanism attachable to each side of a safety helmet and configured to enable a visor to be selectively pivoted. An elongate arm of the double-pivot mechanism includes first and second pivotal couplings, each including a coupling member being a fixed elongate pin having rounded portions at each end, and a coupling region including an aperture defining, along its inner edge, a first notch or aperture within which one of the rounded portions of a respective coupling member is received to define a fixed pivot point, and an arcuate guide wall with which the opposite rounded portion of said respective coupling member engages and having ridges defining grooves or notches for receiving the opposite rounded portion as a respective pivotal coupling is pivoted about the fixed pivot point, each groove or notch defining a respective said visor position.
