US Patent:

50707418, Dec 10, 1991

Filed:

Dec 21, 1990

Appl. No.:

7/633632

Inventors:

Paul R. Ervin - Dearborn MI

Assignee:

Ford Motor Company - Dearborn MI

International Classification:

B62D 118
F16F 712

US Classification:

74492

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.

Appl. No.:

7/495192

Inventors:

Paul R. Ervin - Dearborn MI
Ronald C. Malec - Northville MI

Assignee:

Ford Motor Company - Dearborn MI

International Classification:

B62D 118

US Classification:

280775

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.

Appl. No.:

8/061945

International Classification:

B65D 5116

US Classification:

220 891

Abstract:

A container (10) for compressed gas with a pressure relief member (18) made from a bimorph shape memory material. The bimorph (18) is impermeable by the gas. The bimorph (18) assumes a shape which changes depending on temperature. Below a critical temperature, the bimorph (18) lies in a first (deformed) state, and reverts to a second (remembered) state thereabove. The gas is entrapped within the container (10) when the bimorph (18) assumes the first state. When pressure rises due to temperature increase above the critical temperature, gas may escape from the container (10). This is because the bimorph (18) reverts to its second state, in which a relief gas passageway is opened, thereby relieving gas pressure.
