Abstract
A protective helmet employs an inflatable bladder on the interior of the helmet. The inflatable bladder has cells that extend to the lower rear octants of the wearers head and also to either the crown or upper front octants of the wearers head. The cells are inflatable through a single valve and properly secure the helmet to the wearers head during use. In the preferred embodiment, the helmet is fully lined with resilient material interposed between the bladder and the wearer's head.
Claims10
A protective helmet comprising an outer shell and an inflatable bladder mounted on the interior surface of said shell, said bladder consisting of four diagonally opposed inflatable cells extending downwardly from the crown of said outer shell, two of said cells extending to the lower rear octants of the wearer's head and the other two of said cells extending to the upper front octants of the wearer's head, said cells inflatable through a single valve, whereby inflation of said cells adjusts the position of the helmet to secure the helmet at the lower rear octants and to elevate the helmet from the head at the upper front octants.
A protective helmet comprising:
- an outer shell;
- an inflatable bladder mounted on the interior surface of said shell, said bladder consisting of four diagonally opposed inflatable cells extending to the lower rear octants of the wearer's head and to the upper octants of the wearer's head, said cells inflatable through a single valve;
- and
- a liner formed of resilient material, said liner interposed between said inflatable bladder and the wearer's head;
- whereby inflation of said cells adjusts the position of the helmet to secure the helmet at the lower rear octants and to elevate the helmet from the head at the upper octants.
A protective helmet comprising:
- an outer shell;
- an inflatable bladder mounted on the interior surface of said shell, said bladder consisting of four diagonally opposed inflatable cells extending to the lower rear octants of the wearer's head and to the upper octants of the wearer's head, said cells inflatable through a single valve;
- a liner formed of resilient material, said liner interposed between said inflatable bladder and the wearer's head;
- said liner comprising alternating radially spaced segments of resilient material whereby heat radiated from the wearer's head is ventilated to said outer shell, at least one of said segments comprising a first portion of resilient material having an internal pocket formed therein, and a second portion of resilient material disposed within said pocket, said first portion having a resiliency greater than the resiliency of said second portion;
- whereby inflation of said cells adjusts the position of the helmet to secure the helmet at the lower rear octants and to elevate the helmet from the head at the upper octants.
A protective helmet comprising:
- an outer shell;
- an inflatable bladder mounted on the interior of said shell, said bladder having a plurality of cells extending to the lower rear octants of the wearer's skull and to the upper octants of the wearer's skull, said cells inflatable through a single valve;
- a liner interposed between said inflatable bladder and the wearer's head, said liner comprising an assembly of first interconnected segments of energy absorbing material, said first segments extending downwardly from the crown of said outer shell, and second interconnected segments of energy absorbing material, said second segments extending downwardly from the crown of said outer shell, said second segments engagable with and spaced from said first segments, said liner substantially covering the interior surface of said outer shell, at least one of said segments comprising a first portion of energy absorbing material having an internal pocket formed therein and a second portion of energy absorbing material disposed within said pocket, the energy absorbing material of said first portion having a resiliency different from the resiliency of the energy absorbing material of said second portion.
