Abstract

An interface device for an inflatable individual safety device designed to hold a gas generator in a receiving part of the inflatable individual safety device having at least one positioning element designed to position and hold the gas generator in a final mounting position in the receiving part, and a sealing element arranged between the receiving part and the gas generator positioned and held by the at least one positioning element, in order to obtain a seal in an internal space of the safety device to be inflated by the gas generator.

First claim

The invention claimed is:

1 . An interface device of an inflatable individual safety device, designed to hold a gas generator in a receiving part of the inflatable individual safety device, comprising:
at least one positioning element designed to position and hold the gas generator in a final mounting position in the receiving part, and a sealing element arranged on a radial surface of the gas generator such that the sealing element is disposed between the receiving part and the gas generator positioned and held by said at least one positioning element, in order to obtain a seal in an internal space of the safety device to be inflated by the gas generator, a reference member projecting from the gas generator, the reference member configured to hold or retain the gas generator on the at least one positioning element of the receiving part.

2 . The interface device according to claim 1 , comprising a detection element, designed to detect the gas generator in the final mounting position.

3 . The interface device according to claim 1 , wherein the detection element comprises a presence sensor, designed to be actuated by the reference member of the gas generator.

4 . The interface device according to claim 3 , wherein the reference member comprises a pin.

5 . The interface device according to claim 3 , wherein the presence sensor is designed to be connected to an electronic control unit of the inflatable individual safety device.

6 . The interface device according to claim 1 , wherein said at least one positioning element comprises an elastic return element designed to position and hold the gas generator in the final mounting position.

7 . The interface device according to claim 1 , wherein said at least one positioning element comprises a guide track with a rest portion, the guide track being designed to guide the gas generator towards the final mounting position, defined by the rest portion.

8 . The interface device according to claim 7 , wherein the detection element comprises a presence sensor, designed to be actuated by the reference member of the gas generator and wherein the rest portion is designed to receive the reference member.

9 . The interface device according to claim 1 , wherein the sealing element comprises an O ring.

10 . An inflatable individual safety device, comprising:
the interface device according to claim 1 , a receiving part, a gas generator, and an internal space to be inflated by the gas generator.

11 . The inflatable individual safety device according to claim 10 , wherein the presence sensor is designed to be connected to an electronic control unit of the inflatable individual safety device and comprising the electronic control unit, and wherein the electronic control unit is connected to the gas generator and is designed to ignite the gas generator after reception of an ignition command, if the gas generator is detected in the final mounting position.

12 . The inflatable individual safety device according to claim 11 , wherein the electronic control unit is designed to warn a user if the gas generator is not detected in the final mounting position.

13 . The interface device according to claim 1 , wherein the gas generator is securely mounted by a rotation of the gas generator with less than one full turn.
