A helmet may include an upper-body comprising a first outer shell coupled to a first energy-absorbing shell formed of expanded polypropylene (EPP), expanded polystyrene (EPS), expanded polyurethane (EPU), or expanded polyolefin (EPO). A lower-body may include a second outer shell coupled to a second energy-absorbing shell formed of EPP, EPS, EPU, or EPO, wherein an upper portion of the lower-body is nested within the upper-body and a lower portion of the lower-body extends to an outer surface of a lower portion of the upper-body. A strap anchor may be disposed between the upper-body and the lower-body, and be sandwiched between the upper-body and the lower-body with the strap anchor being adjacent to, and oriented towards, the lower-body. A strap may be coupled to the fastening device and coupled to the strap anchor for coupling the helmet to a head of a user.

A safety helmet with a rotary impact buffering function comprises a shell and an elastic liner arranged in the shell, wherein a gap is formed between the shell and the elastic liner, and a rotary impact buffering device enabling the shell to rotate relative to the elastic liner is arranged between the shell and the elastic liner. When the safety helmet is impacted by external force, the shell has the tendency to rotate relative to the elastic liner under the effect of component force applied to the shell in the tangential direction; however, through tangential deformation of the rotary impact buffering device, the shell can rotate relative to the elastic liner by a certain angle on the premise of keeping the elastic liner unmoved, and thus the impact to users from external force is greatly reduced.

There is disclosed a connector for connecting first and second parts of an apparatus, the connector comprising: a deformable retainer having first and second sides around an inner space; and a first plate positioned within the inner space to provide a low friction interface between the first and second sides of the retainer; wherein the first side of the retainer has a first anchor point that is configured to connect the connector to the first part of the apparatus; and the second side of the retainer has a second anchor point that is configured to connect the connector to the second part of the apparatus.

A helmet can comprise an upper-body comprising an upper outer shell and an upper energy-absorbing material coupled the upper outer shell. The helmet can comprise a lower-body comprising a lower outer shell and a lower energy-absorbing material coupled the outer shell, wherein the lower-body is nested within the upper-body. A strap anchor can be formed without a web and embedded within the upper-body or the lower-body between the upper-body and the nested lower-body. A strap can be coupled to the strap anchor, wherein the strap extends between the upper-body and the lower-body and is threaded through the lower-body to couple the helmet to a head of a user. The strap anchor can comprise a size less than or equal to 10-30 millimeters (mm), by 10-50 mm, by 2-10 mm. The strap anchor can be sandwiched between the upper-body and the lower-body and hidden from view within the helmet.

A helmet having an energy absorbing layer and a sliding facilitator is provided. The sliding facilitator is provided inside of the energy absorbing layer. A method of manufacturing a helmet having a sliding facilitator is further provided. The method includes providing an energy absorbing layer in the mold, and providing a sliding facilitator that contacts the energy absorbing layer.

A suspension connection arrangement for a suspension system for a safety helmet, the suspension system including at least one strap connected to at least one tab, which is attachable between a headband arrangement and at least one headband slot positioned on an internal surface of the safety helmet. The suspension connection arrangement includes: at least one projection member extending from the at least one tab; and at least one keyhole connected to at least one slot, both extending at least partially through a headband member, wherein the at least one keyhole is configured to at least partially receive the at least one projection member therethrough, such that the at least one projection member is configured to slide along the at least one slot, thereby removably attaching the at least one tab to the headband member. A suspension system and a safety helmet are also disclosed.

Provided is a functional headband having an integral cushion band that is applied to welding masks, protective masks, safety helmets, medical helmets, etc. The functional headband includes a main band configured to be worn on a wearer's head, supporting bands connected with the main band and configured to be placed on the wearer's head, adjustment bands connected with both ends of the main band and configured to be adjusted in length, a length adjustment lever configured to adjust the length of the adjustment bands, and cushion bands formed integrally at the supporting bands to cover the wearer's head, thereby supporting the wearer's head in a double supporting structure.

The present application provides a headband arrangement for a welding helmet, comprising: a fixed attachment structure; and a helmet mounting structure cooperating with the attachment structure, wherein at least two stopping positions are defined longitudinally between the attachment structure and the helmet mounting structure, the helmet mounting structure is selectively switchable between an unlocking state and a locking state, wherein in the unlocking state, the helmet mounting structure is slidable between the stopping positions relative to the attachment structure, and wherein in the locking state, the helmet mounting structure can be locked to one of the stopping positions relative to the attachment structure and can be kept there by a magnetic force generated between a pair of magnetic parts.

A helmet, comprising: an outer shell; a head mount, configured to conform to the head of a wearer; and a plurality of connectors, each provided between the outer shell and the head mount and each connected to the outer shell and head mount; wherein the connectors are configured to suspend the head mount within the outer shell such that, in use, an air gap is provided between head mount and the outer shell; wherein the connectors each have a first connection point connected to the outer shell and a second connection point connected to the head mount; and at least one connector is configured such that, under tensile loading between the first and the second connection points, the connector extends with a first modulus of elasticity up to a threshold extension and extends with a second modulus of elasticity beyond the threshold extension.

A helmet comprising an energy absorbing layer (2) and a sliding facilitator (5) is provided. The sliding facilitator is provided inside of the energy absorbing layer (2). A method of manufacturing a helmet comprising a sliding facilitator is further provided. The method comprising the steps of: providing an energy absorbing layer in the mould, and providing a sliding facilitator contacting the energy absorbing layer.
