摘要:
Die Erfindung betrifft einen Schutzhelm (10), insbesondere Fahrradhelm, Skihelm, Skaterhelm, Reithelm oder Motorradhelm, gekennzeichnet durch mindestens eines der folgenden Merkmale: ein in den Sichtbereich des Helmträgers herunter klappbares Visier (20); und/oder eine an der Oberseite des Helms (10) angeordnete, von dem Helm lösbare Wetterschutzabdeckung (40); und/oder eine an der Rückseite des Helms (10) angeordnete, von dem Helm lösbare Rücklichteinrichtung (60); und/oder an den Seiten des Helms (10) angeordnete, von dem Helm lösbare Abdeckungen (80) für die Ohren des Helmträgers. Das Visier (20) ist an der Außenseite des Helms (10) über seitlich angeordnete Scharniere (22) angebracht, die mittels einer Feinrasterung (24) eine Verschwenkung und Halterung des Visiers (20) in mehreren Winkelstellungen zulassen. Der Helm (10) weist an seiner Oberseite mindestens eine Öffnung (12) auf, in die die Wetterschutzabdeckung (40) einsetzbar ist, wobei die Wetterschutzabdeckung (40) eine Form derart aufweist, dass sie die Öffnung (12) im wesentlichen vollständig verschließt. Die Wetterschutzabdeckung (40) wird vorzugsweise mittels an der Wetterschutzabdeckung (40) und in der Öffnung (12) angeordneter Magneteinrichtungen (14, 46) in der Öffnung (12) gehalten.
摘要:
The disclosure relates to a method of producing a hood for a hearing protector by injection moulding of plastic material. The hood (1) is injection moulded to a single contiguous piece employing at least two plastic materials possessing different properties in at least one respect. The plastic materials may be both homogeneous and in porous or foamed form. A hood (1) for a hearing protector is produced from plastic by injection moulding. The hood (1) includes at least two portions or layers (6, 7, 8; 10, 11; 13, 14) which are united to one another. The portions or layers (6, 7, 8; 10, 11; 13, 14) consist of plastic materials with different properties in at least one respect.

A protective helmet (60) having a circumferential support (61) mounting a helmet shell (62) and visor guides (81), a visor (80) movable within the shell (62) between lowered and raised positions and guided by the visor guides (81), a head harness (75) carried by the support (61) and ear defenders (90, 91) movably mounted at opposite sides of the helmet. The helmet has a removable air filter unit (71) which is fitted in an interference fit within an air inlet cavity of the helmet.
摘要:
A resilient annular earseal (62) for sealing the region between an earcup shell (12) and a wearer's head is formed with an aperture for receiving the wearer's ear and has an outer peripheral portion (64) projecting a predetermined first distance toward the wearer's head and an inner peripheral portion (65) projecting a predetermined second distance toward the wearer's head that is appreciably greater than the first distance. Since the inner peripheral portion (65) contacts the wearer's head along a strip that is closer to the ear, and hence more predictable in its three-dimensional contour, it forms an effective seal around the entire periphery of the ear.
摘要:
A safety helmet for water sports comprising a shell (1), an inner frame (3), a retractible visor (2) and a head retentioning hood. A wiper means comprising two blades (4, 5) is disposed at the front of the shell between the shell (1) and inner frame (3). The blades (4,5) are oppositely disposed in spaced apart and parallel relationship to respectively engage the inner and outer faces of the visor (2), so that upon moving the visor (2) from an open to a closed position, or vice versa, the blades (4, 5) wipe across the face of the visor to clean the same. The head retentioning hood is segmented and is made from both resilient and substantially non-extendible material to intimately engage the head of the wearer so as to impede wind and water penetration of the ears, whilst maintaining comfort and ventilation of the head without limiting freedom of movement.
