Abstract
In one aspect, a protective headwear is provided and includes a support member configured to engage a user's head, an outer shell coupled to the support member and rotatable relative to the support member between a first position and a second position, and a member coupled between the support member and the outer shell to reduce angular velocity of the outer shell as it moves from the first position to the second position. In one aspect, the protective headwear is a welding helmet.
Claims30
A protective headwear comprising:
- a support member configured to engage a user's head;
- an actuator;
- an outer shell coupled to the support member and rotatable relative to the support member between a first position and a second position, the actuator moveable relative to the outer shell to apply varying levels of force to the outer shell;
- and
- a member coupled between the support member and the outer shell to reduce angular velocity of the outer shell as it moves from the first position to the second position;
- wherein the member includes a first portion and a second portion formed separately from each other and formed separately from the support member and the outer shell, and wherein the first portion and the second portion are moveable relative to each other as the outer shell moves from the first position to the second position;
- wherein the first portion includes a first surface and the second portion includes a second surface, wherein the first surface and the second surface directly engage each other, the first portion comprising a first bore which is asymmetrical and the second portion comprising a second bore which is asymmetrical, the outer shell disposed between the actuator and the member.

A protective headwear comprising:
- a support member configured to engage a user's head;
- an outer shell coupled to the support member and rotatable relative to the support member between a first position and a second position;
- and
- a member coupled between the support member and the outer shell and including a first portion and a second portion, wherein the first portion is thicker near a first end of the first portion and thinner near a second end of the first portion, and wherein the second portion is thicker near a first end of the second portion and thinner near a second end of the second portion, wherein the first and second portions of the member interact to reduce angular velocity of the outer shell as it moves from the first position to the second position;
- and
- wherein the first portion comprises a first bore which is asymmetrical and the second portion comprises a second bore which is asymmetrical.
