ABSTRACT:
A collapsible steering column assembly is provided, and includes a receiver which slidably receives a telescope housing. The telescope housing includes an internally collapsible shaft. A lower universal joint is removably secured to the receiver for supporting a collapsible intermediate shaft. The intermediate shaft is collapsible in the direction of the engine compartment upon presentation of sufficient load upon the telescope housing to disconnect the lower universal joint from the receiver once the telescope housing itself has been internally collapsed. A lower bearing retainer supports the lower universal joint within the receiver. Shearable rivets secure the lower bearing retainer to the receiver. The rivets shear when sufficient load is present.
