Battery disconnect device

A battery disconnect device comprising:

• a breaker having an indicator on a portion thereof;
• a housing defining a chamber, the breaker being disposed in the chamber;
• and
• a bus bar disposed through the housing,
• wherein combustion gas from a gas generator causes the breaker to move from a first position to a second position, wherein movement from the first position to the second position causes the breaker to break the bus bar into at least two separate pieces, and the indicator is visible from an external surface of the housing when the breaker is in the second position,
• wherein the breaker has a pivot portion and an actuation portion, the actuation portion having an actuation face, the pivot portion having an axis of rotation about which the breaker is pivotable, wherein the chamber is in fluid communication with a gas generator via an inlet defined by an inlet wall of the housing, the bus bar extending through the housing and the chamber, wherein the actuation face is adjacent the inlet and inlet wall in the first position, and combustion gas from the gas generator pushes on the actuation face to cause the breaker to pivot about the axis of rotation of the pivot portion to a second position, wherein in the second position, the actuation face is spaced apart from the inlet and inlet wall,
• wherein:
• the actuation face lies in a first plane and a second face lies in a second plane,
• the inlet wall of the chamber lies in a third plane,
• the housing further comprises a stop wall that lies in a fourth plane and an arcuate shaped wall disposed between the stop wall and the inlet wall, the third and fourth planes intersecting opposite the arcuate shaped wall of the housing,
• the breaker comprises an arcuate shaped face extending between the actuation face and the second face, the arcuate shaped face being opposite and spaced apart from the pivot portion,
• the arcuate shaped wall of the chamber faces the arcuate shaped face of the breaker, and
• the pivot portion of the breaker is disposed adjacent the intersection of the third and fourth planes,
• wherein the arcuate shaped face of the breaker comprises at least one tooth that extends away from the arcuate shaped face, the tooth engaging the arcuate shaped wall after the breaker rotates from the first position to the second position to prevent rotation from the second position to the first position, and
• wherein the at least one tooth comprises a first plurality of teeth and the arcuate shaped wall defines a second plurality of teeth that extend away from the arcuate shaped wall and engage the first plurality of teeth after the breaker rotates from the first position to the second position to prevent rotation from the second position to the first position.
