1. An airbag module comprising:
- a canister;
a cover coupled to said canister, said canister and cover defining a cavity;
a nub provided on one of said cover and canister;
a slot provided on the other of said cover and said canister, the slot being a hole having a receiving section that is within the hole and an engaging section that is within the hole extending from said receiving section;
wherein said nub is disposed in said receiving section when said cover is in a neutral position relative to said canister and, when said cover is moved relative to said canister in the direction toward a final installed position from said neutral position, said nub engages said engaging section to create a frictional force resisting movement of said cover relative to said canister.

Abstract
An air bag module including a canister and a cover coupled to said canister. One of the cover and canister has a projection and the other of the cover and canister has an opening. The projection is disposed in the opening and engages the other of the cover and canister to restrict movement of the cover relative to the canister and create a frictional force acting to resist movement of the cover relative to the canister.

2. An airbag module comprising:
-
a canister; a cover coupled to said canister, said canister and cover defining a cavity, one of said cover and canister having a nub with a width and the other of said cover and said canister having a slot with a receiving section and a tapered section extending from said receiving section, said receiving section having a width that is larger than said nub width and said tapered section having a width that narrows as said tapered section extends from said receiving section; wherein said nub is disposed in said receiving section when said cover is in a neutral position relative to said canister and, when said cover is moved relative to said canister in the direction toward a final installed position from said neutral position, said nub is moved into said tapered section to create an increasing frictional force resisting movement of said cover relative to said canister, said frictional force increasing as said canister effects relative movement in a direction away from said cover; an inflator disposed in said cavity; and an air bag disposed in said cavity and operably associated with said inflator. - View Dependent Claims (3, 9)

4. A method of assembling an airbag canister within a vehicle instrument panel comprising:
-
coupling a cover to a canister by displacing the cover to a neutral position relative to the canister so as to realize limited slip interface between the cover and the canister; disposing tab wings on the canister into cutouts on the cover; displacing the cover until the tab wings are not aligned with the cutouts on the cover; engaging a locking nub on the cover into a receiving section of a locking slot on the canister; placing the canister with the cover in said neutral position within a cavity defined by an instrument panel of a vehicle; connecting the canister to the instrument panel with a fastener assembly; enabling adjustment of the cover relative to the canister after initial coupling of the airbag canister within the vehicle instrument panel; tightening the fastener assembly to securely couple the canister to the instrument panel; and displacing the cover to a final installed position relative to the canister. - View Dependent Claims (5, 6, 7, 8)
