摘要:
A faceshield that is securable to a protective helmet or headband having an indexable pivot joint (10) which utilizes an interference fit between an O-ring (14) and radially spaced lug (52, 92) sets. The O-ring (14) is compressed when the crests (54, 94) of the two sets of lugs (52, 92) are radially aligned. This interference holds the faceshield in a desired indexed position.
摘要:
A suspension (10) for a protective helmet having a headband section (30) that encompasses at least a part of a user's head and a crown support section (40) connected to the headband section (30). The headband section (30) and the crown support section (40) of the suspension are fabricated from an integral piece of material. The suspension system may also have a headband (30) comprising a section of elastic material. Alternatively, the headband (30) may comprise a forward band (600) having a first section (620) to contact the forehead of the user and a second section (630) adapted to be positioned between the user's head and the crown support section of the suspension during use thereof.
摘要:
The present invention provides a self-contained breathing apparatus ("SCBA") having a personal alert safety system ("PASS") fully integrated therewith. The PASS is structurally integrated with the SCBA such that it is protected from damage by both the air cylinder and the frame. The integrated PASS device is not only automatically activated when the SCBA is being used but can still be activated manually if the SCBA is not in service. Additionally, the integrated PASS device utilizes a unique electrical/mechanical connection assembly between its various parts which greatly increases its ruggedness and durability.
