  • Patent number: 5070741
    Abstract: A collapsible steering column arrangement for a vehicle is disclosed which comprises a pair of offset shafts and an extrudable housing. One of the shafts is generally fixed with respect to the vehicle and includes a first gear, a second gear and the other shaft includes in rotational driving engagement with the first gear on the one shaft for steering the vehicle and is movable with respect to the one shaft in response to an axial load imposed on the steering column arrangement. The energy of the axial load is absorbed when the second gear extrudes through the housing. In an alternative embodiment, one of the shafts includes a first gear and the other shaft includes a second gear in rotational driving engagement with the first gear to transfer rotation between the shafts, one of the gears having teeth with a width greater than the teeth of the other gear to allow the length of the steering column to be adjusted according to the driver's preference.

  • Patent number: 5052715
    Abstract: A collapsible steering column is mounted to a vehicle by upper and lower bend straps. The bend straps are located such that their energy-absorbing function is not susceptible to interference by intrusion of the dash during front end impact. The steering shaft length is minimized through the use of a break-away coupling located substantially inward of the dash and within the passenger compartment.
