Abstract: A vehicle steering column has a rake adjustment mechanism which includes a rake bracket having a rake slot provided with rake slot teeth. A tooth lock is supported in the rake slot with teeth opposing the rake slot teeth. A rake bolt is rotatable to a first rotative position to move the tooth lock to a retracted position with the teeth of the tooth lock out of engagement with the rake slot teeth. The bolt is axially rotatable to a second rotative position permitting the tooth lock to be moved to a locking position by a spring in which the teeth of the tooth lock engage the rake slot teeth. The bolt, when in the second rotative position, is movable, in response to an application of an impact force on the steering column to collapse the steering column, into bearing engagement with the tooth lock to positively retain the tooth lock in the locking position. The steering column is also provided with a release mechanism having shear pins and an energy absorption mechanism.

Abstract: An energy absorbing device for a collapsible steering column has a plurality of plastically deformable straps each with one end connected to the steering column and an opposite end bent around an anvil connected to stationary vehicle support structure. When the steering column collapses, the straps unwind from the anvils, thereby resisting steering column collapse and absorbing energy. One or more of the straps may be cut in two by a knife at the time of the collision, thereby removing it from the energy absorbing system. In another form of the invention, an energy absorbing strap extends around a piston which has two or more different size anvils. The piston is axially movable in a cylinder to positions surrounding one or another of the anvils. The strap is drawn over the anvil it surrounds when the steering column collapses, thereby resisting collapse of the steering column and absorbing a certain amount of energy depending on the size of the anvil.

Abstract: A system for steering the wheels of a vehicle. The system includes a steering gear provided with a steering rack reciprocable in a power cylinder. A steering shaft has a pinion meshing with the steering rack. A hydraulic fluid system assists the reciprocation of the steering rack. The hydraulic fluid system includes a power piston reciprocable in the power cylinder. A control valve directs hydraulic fluid from a pump to the power cylinder at one side or the other of the piston, depending on the direction of rotation of the steering shaft. A lock valve is operable when closed to lock the rack against reciprocation to prevent steering of the wheels by preventing fluid flow in the hydraulic fluid system. The lock valve is controlled by a solenoid-operated electronic controller.
