Abstract
An air bag module has an air bag housing with an opening for deploying the air bag. The opening is provided with the cover. A connector attaches the cover to the air bag housing. The connector has an aperture and a protrusion for engaging the aperture. The aperture is located on one of the air bag housing and the cover while the protrusion is located on the other of the air bag housing and the cover. The protrusion has a first portion, a second portion and a third portion. The first portion extends from a surface of one of the air bag housing and the cover while the second portion extends transversely from the first portion and the third portion extends transversely from the first portion.
Claims20
An air bag module comprising:
- an air bag housing having an opening for deploying an air bag;
- a cover for covering said opening;
- a connector for attaching said cover to said air bag housing, said connector having an aperture and a protrusion for engaging said aperture, said aperture on one of said air bag housing and said cover and said protrusion on the other of said air bag housing and said cover;
- and
- wherein said protrusion has a first portion, a second portion and a third portion, said first portion extending from a surface of one said air bag housing and said cover, said second portion extending transversely from said first portion, and said third portion extending transversely from said first portion.
An air bag module comprising:
- an air bag housing having an opening for deploying an air bag;
- a cover for covering said opening;
- a connector for attaching said cover to said air bag housing, said connector having an aperture and a protrusion for engaging said aperture, said aperture on one of said air bag housing and said cover and said protrusion on the other of said air bag housing and said cover;
- and
- wherein said aperture is flexible between a first aperture dimension and a second aperture dimension, said first aperture dimension larger than a protrusion dimension and said second aperture dimension smaller than said protrusion dimension.
A method of assembling an air bag module having an air bag cover and an air bag housing, the method comprising the steps of:
- expanding an aperture on the air bag cover to a first aperture dimension from a second aperture dimension, the first aperture dimension larger than the second aperture dimension;
- disposing a protrusion on the air bag housing in the aperture while in the first aperture dimension;
- and
