PROTECTIVE HEADGEAR

摘要

Protective headgear such as a motorcycle helmet is described which provides an improved fit for a wearer. The helmet (1) includes an outer rigid shell (2) over a polystyrene liner (8). An inner lining (3) abuts the skull and head and neck (if required) of the wearer and is manufactured from a soft material. Interposed between the shell (2) and lining (3) is an inflatable bladder (4). The bladder (4) is a hollow cell(s) which essentially follow(s) the contours of the head of the wearer of the helmet (1). A bite valve (5) is located at the base of the bladder (4). With the bladder (4) deflated, the helmet is positioned on the head of the wearer and the chin strap (7) is tightened to an appropriate fit. On blowing air through the valve (5), the bladder (4) is gradually inflated, the bladder (4) then bearing upon the inner lining (3) which, in turn, is forced into contact with the contours of the skull and head (and neck) of the wearer of the helmet (1).
