Helmets comprising additively-manufactured components

A helmet comprising:

• an outer shell;
• and
• an impact absorbing inner liner, the impact absorbing inner liner comprising:
• a first padding component disposed within the outer shell, the first padding component being configured to compress when the helmet is impacted;
• and
• a plurality of second padding components disposed within the outer shell at selected locations around a wearer's head when the helmet is worn, the first padding component and the second padding components each defining a separate padding forming parts of the impact absorbing inner liner,
• each second padding component of the plurality of second padding components comprising:
• an inner head facing surface, an outer shell facing surface and outer peripheral surfaces extending between the head facing surface and the outer shell facing surface, at least one of the outer peripheral surfaces comprising an open surface that provides multiple openings therethrough;
• and
• an array of shock absorbers extending between the head facing surface and the outer shell facing surface of the second padding component and configured to deform when the helmet is impacted,
• wherein:
• each the second padding component has a plurality of channels extending therethrough in a direction that is generally radial to a wearer's head when the helmet is worn;
• each channel in a specific one of the second padding components comprises an inner peripheral surface extending between a first respective opening in the head facing surface of the specific one of the second padding components to a second respective opening in the shell facing surface of the specific one of the second padding components;
• the inner peripheral surface of each the channel comprises an open surface that provides multiple openings therethrough;
• and
• each the channel has a cross-sectional area that is greater than a cross-sectional area of any one of the openings through the open surface of the inner peripheral surface of the channel.
