摘要:
The invention relates to a cover (1) for helmet (2), particularly for jet kind helmet (2), characterised in that it is comprised of at least partially elasticised material, having a shape conformable to the shape of the jet kind helmet (2), and in that it is provided with means (3) for coupling with the same helmet (2).
摘要:
An improved helmet (10) constructed with a rigid shell (20) having a soft outer covering (16) which absorbs impacts and disperses energy thereby protecting the wearer of the helmet, as well as protecting the impacting object. When used for contact sports such as football, this covering is effective in preventing injuries resulting when the helmet is used as a striking object. The covering may be applied in segmented pieces or as a continuous layer around the shell which forms a solid frame-like structure. A face mask (30) can also be covered with soft, durable covering (36) and be mounted in such a manner to allow the covering to act as a shock absorber against sliding of the mask due to external forces.
摘要:
A flexible protective helmet assembly comprising an outer layer of impact resistant segments (11-17) overlying an inner layer of closely abutting impact resistant and energy absorbent structures (18-24) fixedly attached and interconnected by flexible elastic panels (26-32) and including an elliptically annular crown structure (25).
摘要:
A protective hat for children and adults comprises a head-enveloping member constructed of a core of impact absorbent foam, encapsulated within a shell of textile fabric material, the textile fabric material providing the inner and outer surfaces of the hat. The core is so constructed as to provide for conformity to the shape of head of the wearer, and to allow for ventilation. The bulk and density of the foam core is such that, in sizes for children, the hat provides significant buoyancy.
摘要:
An article made from a thermoplastic composition such as customizable mouldable parts of articles such as dental plates or hand grips or sports equipment which composition is set below 37°C and is conformably mouldable between about 50°C and 95°C. Such a composition includes a methacrylate polymer which may soften or become liquid in the range of 50°C to 95°C and may be mixed with another such polymer which is set at that temperature range so that a mouldable mass is formed, for example by warming in warm water. The invention includes a method of forming the composition.
摘要:
A one-piece chinstrap-napestrap assembly (36) for a helmet (20) in which a pair of napestraps (42, 44) secured to the nape portion of the helmet interior at laterally spaced locations extend around the lower periphery of the helmet, crossing each other, and pass outwardly through slots (76, 78) formed in the front of the helmet to receive the ends of an adjustable chinstrap (40). Adjustment of the chinstrap (40) at the front of the assembly produces a simultaneous adjustment of the crossing napestrap portions at the rear of the assembly without the necessity for independent adjustment of the latter strap portions. A padded napestrap retainer (38) secured by straps (68, 70) to the same locations on the nape portion of the helmet is formed with intersecting passages (P1, P2) for receiving the crossing strap portions. The retainer (38) reduces chafing and urges the crossing napestrap portions toward the rear of the helmet (22) when the chinstrap (40) is released to facilitate donning and doffing.
