Abstract:
1. A helmet suspension system configured for use with a helmet to mitigate large accelerations of the helmet relative to the wearer's body, the helmet suspension system comprising: a guide member carried by the helmet; a first member moveable relative the guide member; a first arm having a first end portion and a second end portion, the first end portion being connected to the first member, the first arm being moveable relative to the guide member as the first member moves within the guide member; and a first damper moveably connected to the second end portion of the first arm, the first damper being configured to define an acceleration threshold of the second end portion relative to the first damper and to allow movement of the first arm relative to the first damper when the motion of the first arm is below the acceleration threshold and restrict movement of the first arm relative to the first damper when the motion is above the acceleration threshold; a second member moveable relative the guide member; a second arm having a first end portion and a second end portion, the first end portion being connected to the second member, the second arm being moveable relative to the guide member as the second member moves within the guide member; and a second damper moveably connected to the second end portion of the second arm, the second damper being configured to define an acceleration threshold of the second end portion relative to the second damper and to allow movement of the second arm relative to the second damper when the motion of the second arm is below the acceleration threshold and restrict movement of the second arm relative to the second damper when the motion is above the acceleration threshold; and a third member moveable relative the guide member; a third arm portion having a first end portion and a second end portion, the first end portion being connected to the third member, the third arm being moveable relative to the guide member as the third member moves within the guide member; a third damper moveably connected to the second end portion of the third arm, the third damper being configured to define an acceleration threshold of the second end portion relative to the third damper and to allow movement of the third arm relative to the third damper when the motion of the third arm is below the acceleration threshold and restrict movement of the third arm relative to the third damper when the motion is above the acceleration threshold; a fourth member moveable relative the guide member; a fourth arm having a first end portion and a second end portion, the first end portion being connected to the fourth member, the fourth arm being moveable relative to the guide member as the fourth member moves within the guide member; and a fourth damper moveably connected to the second end portion of the fourth arm, the fourth damper being configured to define an acceleration threshold of the second end portion relative to the fourth damper and to allow movement of the fourth arm relative to the fourth damper when the motion of the fourth arm is below the acceleration threshold and restrict movement of the fourth arm relative to the fourth damper when the motion is above the acceleration threshold.
