Abstract
A gas damped deceleration switch activates a vehicle occupant safety device in response to deceleration of a vehicle. The deceleration switch comprises a mass supported for movement in response to deceleration. A base structure has surfaces defining a chamber and a gas flow inlet communicating with the chamber. A pressure reduction is caused in the chamber in response to movement of the mass. The pressure reduction in the chamber restrains movement of the mass and causes a flow of gas into the chamber through the inlet. A movable control member controls the pressure reduction and movement of the mass by adjusting the flow of gas into the chamber through the inlet. The control member is slidable across the inlet to control a flow of gas into the inlet. A spring biases the movable control member into slidable contact with the base structure.
