Safety device for a gas-conducting device

A safety device for interrupting a gas flow within a gas-conducting device, the device comprising:

• an inertia mechanism;
• and
• a reaction mechanism,
• wherein an inertia body of the inertia mechanism is configured to move from a resting position in case of an acceleration above a specifiable acceleration threshold value acting on the inertia body,
• wherein the inertia mechanism is configured to activate the reaction mechanism due to the movement of the inertia body,
• wherein when activated, the reaction mechanism is configured to interrupt the gas flow within the gas-conducting device,
• wherein the safety device is free of gas flowing through it,
• wherein the inertia mechanism has a pit in a housing for accommodating the inertia body,
• wherein the inertia body is, in a normal state, in the resting position in the pit,
• wherein the inertia mechanism has a transfer pin which, in the normal state, holds the inertia body in the resting position and which, in an activated state, prevents the inertia body from returning to the resting position,
• wherein the safety device has a sliding punch,
• wherein the sliding punch and the transfer pin are mechanically coupled to one another such that the sliding punch prevents, in the normal state, a movement of the transfer pin away from the pit.
