Passenger side airbag module
First Claim
1. A passenger side airbag module comprising:
- A) a reaction can having a sidewall and a bottom wall defining an open-topped airbag cushion storage compartment, the bottom wall including an integral mounting ring defining an inflator-receiving opening;
B) a retainer having a generally cylindricalsleeve with upper and lower ends, a top wall extending inwardly from the upper end of the cylindrical sleeve and defining an opening, and a retainer ring extending outwardly from the cylindrical sleeve and secured to the mounting ring of the reaction can with the sleeve extending upwardly from the inflator-receiving opening in the bottom wall of the reaction can;
C) an airbag cushion including an inflatable body and a reinforced mounting collar defining a mouth, the mounting collar clamped between the mounting ring of the reaction can and the retainer ring of the retainer secured thereto with the mouth aligned with the inflator-receiving opening in the bottom wall of the reaction can, the inflatable body of the airbag cushion folded and substantially packed in the storage compartment of the reaction can for deployment from the open top thereof; and
D) an inflator for producing inflation gas, the inflator having an elongated cylindrical body and an outlet cap at one end thereof for delivering inflation gas, the inflator secured to the retainer with the inflation gas outlet cap extending through the opening defined by the top wall of the retainer, a portion of the inflator body adjacent the gas outlet cap received in the cylindrical sleeve of the retainer and a portion of the inflator body extending through the inflator-receiving opening in the bottom wall of the reaction can and the mouth of the airbag cushion.

Abstract
A passenger side airbag module includes a reaction can having a generally cylindrical sidewall and a bottom wall defining an open-topped airbag cushion storage compartment, the bottom wall including an integral annular mounting ring defining an inflator-receiving opening. A retainer has a cylindrical sleeve with a top wall extending inwardly and a retainer ring extending outwardly from the lower end of the sleeve. An airbag cushion includes an annular mounting collar which is clamped between the retainer ring and the mounting ring. An inflator has an elongated cylindrical body partially received in the cylindrical sleeve of the retainer with a gas outlet cap extending through the top wall of the retainer to deliver inflation gas to the interior of the airbag cushion. The gas outlet cap is welded to the retainer to secure the inflator. A portion of the inflator body extends below the reaction can, and the mounting collar is positioned around the inflator body to cushion against rattles. Mounting studs are provided for securing the bottom wall of the inflator to a vehicle panel.

19. A passenger side airbag module comprising:
-
A) a one-piece, unitary reaction can having a generally cylindrical sidewall and a bottom wall together defining an open topped airbag cushion storage compartment, the sidewall tapering outwardly from the bottom wall to the open top thereof and the bottom wall including an annular mounting ring defining an inflator-receiving opening;
B) a retainer having a generally cylindrical sleeve with upper and lower ends, a top wall extending inwardly from the upper end of the cylindrical sleeve and defining an opening, and a retainer ring extending outwardly from the lower end of the cylindrical sleeve and having substantially the same diameter as the annular mounting ring, the retainer ring secured to the mounting ring of the reaction can by means of a plurality of spaced-apart studs extending from the retainer ring through openings defined in the annular mounting ring, with the sleeve of the retainer extending upwardly from the inflator-receiving opening in the bottom wall of the reaction can;C) an airbag cushion including an inflatable body and reinforced mounting collar defining a mouth, the mounting collar clamped between the annular mounting ring of the reaction can and the retainer ring of the retainer, the mounting collar of the airbag including at least one slit for accommodating the retainer ring preparatory to clamping the mounting collar between the retaining ring and mounting ring; and
the mounting collar defining a plurality of openings through which the studs are accommodated, the body of the airbag cushion folded and substantially packed in the storage compartment of the reaction can for deployment from the open top thereof;D) an inflator for producing inflation gas, the inflator having an elongated cylindrical body and an outlet cap at one end thereof for delivering inflation gas, the gas outlet cap extending through the opening defined by the top wall of the retainer and welded to the top wall of the retainer, a portion of the inflator body adjacent the outlet cap received in and supported by the cylindrical sleeve of the retainer, the inflator body passing through the inflator-receiving opening in the bottom wall of the reaction can and the mouth of the airbag cushion with a further portion of the inflator body extending from the bottom of the reaction can. - View Dependent Claims (20)
