Embodiment Construction

[0025] Reference is now made to the following description and accompanying drawings, which illustrate illustrative methods in detail. Although the drawings represent some possible approaches, the drawings are schematic in nature and not drawn to scale, some features have been exaggerated or removed in order to better describe and illustrate the invention. Furthermore, it is not the purpose of the description given herein to be exclusive or to limit or restrict the claims to the exact form and configuration shown in the drawings or disclosed in the detailed description.

[0026] refer to Figure 1-4 , an exemplary occupant restraint system 100 ("system") may include a driver airbag module 102 ("airbag module") having an inflatable cushion 104 with multiple deployment paths for reducing the effects of disengagement Forces on the chin, neck and chest of occupants in the seated position and belted occupants. The system further includes a steering column 106 surrounded by a shrou...

Abstract

An exemplary driver airbag module may include an inflatable cushion having a chamber that inflates up to a maximum volume. The airbag module may also have a fabric diffuser disposed within the chamber. The inflatable cushion and the fabric diffuser can be configured to deploy at least a portion of the inflatable cushion forward of a steering wheel in response to an out-of-position occupant preventing rearward expansion of the inflatable cushion up to the maximum volume.

Description

Background technique [0001] To reduce the forces loaded on the chin and neck, as well as the forces punching the occupant's chest in the disengaged position, automakers are working on airbag modules. This force can be reduced by folding the main pad to suit the configuration of the particular vehicle carrying the module. However, in full-vehicle test mode, the folding technique can cause undesired changes in response to seat belts or seated occupants. Furthermore, modifications to adjust the folding technology for a particular vehicle require extensive retesting and significant associated costs. [0002] Accordingly, it would be desirable to provide a driver airbag module that provides low risk deployment (LRD) for both an engaged and disengaged occupant. Contents of the invention [0003] An exemplary driver airbag module may include an inflatable cushion having a chamber that is inflatable to a maximum volume. The airbag module may also have a fabric diffuser disposed w...
