Abstract A safety steering column extends between a steering wheel assembly for a vehicle and a steering gear assembly for the vehicle. A breakaway universal joint assembly in the steering column includes a spider having four arms disposed in a crosslike configuration. A first yoke is releasably coupled to a first two opposed arms of the spider, while a second yoke is coupled to the other two opposed arms of the spider. The first yoke is formed with two pockets that open in directions generally parallel to a longitudinal axis of the steering column and the end portions of the corresponding arms of the spider are releasably press-fit into the pockets. Thus, when a load in excess of a predetermined release load is exerted on the joint assembly, the first yoke will release the ends of the spider arms.
In a safety steering column for a vehicle having a steering wheel assembly and a steering gear assembly, the steering column extending between the steering wheel assembly and the steering gear assembly, the improvement comprising a breakaway universal joint assembly that includes a spider having four arms disposed in a cross-like configuration, a first yoke releasably coupled to a first two opposed arms of the spider, and a second yoke coupled to a second two opposed arms of the spider, the first yoke being adapted to release the first two opposed arms in response to a load exerted on the joint assembly which exceeds a predetermined load and which is exerted in a direction generally parallel to a longitudinal axis of the steering column.
