Problems solved by technology

However, the inventors have recognized that in some situations, particularly during situations in which the wearer of the helmet is not exposed to the more serious risks for which the helmet is designed, sliding of one part of the helmet relative to another may give Inconvenience to the user, especially if the extent to which one part slides relative to the other becomes too great

Embodiment Construction

[0027] The proportions of the thicknesses of the various layers in the helmet depicted in the figures are exaggerated in the drawings for the sake of clarity, but can of course be adjusted according to needs and requirements.

[0028] figure 1 A first helmet 1 of the class discussed in WO 01 / 45526 is depicted for providing protection against oblique impacts. This type of helmet can be any of the types discussed above.

[0029] The protective helmet 1 is constructed with an outer shell 2 and an inner shell 3 arranged inside the outer shell 2 for contact with the wearer's head.

[0030] Arranged between the outer shell 2 and the inner shell 3 is a sliding layer 4 or a sliding aid and thus enables a displacement between the outer shell 2 and the inner shell 3 . In particular, as described below, the sliding layer 4 or the sliding aid can be configured such that sliding can occur between the two components during an impact. For example, it may be configured to slide under force...

Abstract

Disclosed is a helmet comprising: an inner shell (22); an outer shell (21); a sliding interface (23) between the inner shell and the outer shell; and a switch (20) configured to be selectively switchable between first and second discrete modes, the first mode allowing relative sliding between the inner shell and the outer shell at the sliding interface in response to an impact to the helmet, the second mode preventing relative sliding between the inner shell and the outer shell at the sliding interface.

Description

technical field [0001] The present invention relates to helmets. Background technique [0002] As we all know, helmets are used in a variety of activities. These activities include combat and industrial uses such as protective helmets for soldiers and hard hats or helmets for construction workers, miners or operators of industrial machinery. Helmets are also common in sports activities. For example, protective helmets can be used in ice hockey, cycling, motor sports, auto racing, skiing, snowboarding, skating, skateboarding, equestrian activities, American football, baseball, rugby, cricket, lacrosse, rock climbing, golf, Airsoft and paintballing. [0003] Helmets can be fixed size or adjustable to fit heads of different sizes and shapes. In some types of helmets, such as commonly found in ice hockey helmets, adjustability can be provided by moving parts of the helmet to change the outer and inner dimensions of the helmet. This can be achieved by having the helmet have ...
