Bladder for cushion pads, related systems and methods

A helmet comprising:

• an outer shell defining a cavity for receiving a head of a person;
• a support structure coupled to the outer shell and positioned within the cavity, the support structure comprising a web of support material positioned in a spaced-apart relation relative to the outer shell and defining a plurality of openings;
• and
• a plurality of cushion pads provided within respective openings of the web of support material, the plurality of cushion pads forming a liner of the helmet, wherein each cushion pad includes:
• an internal structure having shock-absorbing properties;
• a bladder enclosing the internal structure to define an internal volume of the internal structure;
• and
• a valve passing through the bladder and being in fluid communication with the internal structure, the valve being configured to allow a passage of an airflow into or out of the internal structure, such that the internal pressure of the internal structure varies when an impact force is applied to the cushion pad.
