Abstract

A vehicle occupant protection system (180) includes an inflatable vehicle occupant restraint device (202) positioned in the vehicle, and a gas generating system (8) coupled to the inflatable restraint device (202) for providing inflation fluid to inflate the vehicle occupant restraint device. The gas generating system (8) is secured to the vehicle by a mounting mechanism (10) having a first strap (12) wrapped around a portion of the gas generating system (8) and a second strap (14) coupled to the first strap (12) and wrapped around a portion (24) of the vehicle.

Claims

1. A mounting mechanism for securing a gas generator to a vehicle, the mounting mechanism comprising:

a first strap adapted to wrap around a portion of the gas generator;

a second strap coupled to the first strap and adapted to wrap around a portion of the vehicle;

a locking mechanism for securing the first strap around the portion of the gas generator; and

a locking mechanism for securing the second strap around the portion of the vehicle,

wherein at least one of the first strap and the second strap includes a plurality of openings formed therealong adapted for receiving a portion of the at least one of the first strap and the second strap therein, and wherein the locking mechanism comprises a locking feature incorporated into at least one opening of the plurality of openings, each locking feature being adapted for lockingly engaging the portion of the at least one of the first strap and the second strap.

2. A vehicle occupant protection system including a gas generator and a mounting mechanism in accordance with claim 1 for securing the gas generator to a vehicle.

3. An airbag module comprising:

a gas generating system;

a mounting mechanism in accordance with claim 1 for securing the gas generating system to a vehicle and

an airbag operatively coupled to the gas generating system.

4. A method for securing a gas generator to a vehicle comprising the steps of:

providing a first strap adapted to wrap around a portion of the gas generator;

providing a second strap coupled to the first strap and adapted to wrap around a portion of the vehicle;

wrapping the first strap around the portion of the gas generator so as to form a snug fit between the first strap and the portion of the gas generator;

securing the first strap around the portion of the gas generator so as to substantially maintain the snug fit between the first strap and the portion of the gas generator;

wrapping the second strap around the portion of the vehicle so as to form a snug fit between the second strap and the portion of the vehicle; and

securing the second strap around the portion of the vehicle so as to substantially maintain the snug fit between the second strap and the portion of the vehicle,

wherein at least one of the first strap and the second strap includes a plurality of openings formed therealong adapted for receiving a portion of the at least one of the first strap and the second strap therein,

and wherein a locking mechanism is incorporated into the at least one of the first strap and the second strap, the locking mechanism including a locking feature incorporated into at least one opening of the plurality of openings, each locking feature being adapted for lockingly engaging the portion of the at least one of the first strap and the second strap.

5. An airbag module including a gas generator secured to a vehicle in accordance with the method of claim 4.

6. A vehicle occupant protection system including a gas generator secured to a vehicle in accordance with the method of claim 4.
