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 includes a plastically deformable metal strap for resisting the collapse of a steering column. The strap is initially deformable into one or more V-shaped wave formations by anvils to increase the energy required to advance the strap, thereby increasing the resistance to collapse of the steering column. One of the anvils may be removed to eliminate one of the wave formations and thereby reduce the amount of resistance to collapse of the steering column. Alternatively, the position of an anvil may be varied to vary the shape of a wave configuration from a deep V to a shallow V.

Abstract: An energy absorbing device for a collapsible steering column of a vehicle includes an M-shaped plastically deformable strap for imposing a resistance to collapse of the steering column when the steering column collapses in a vehicle collision. An anvil adjusts the resistance to collapse imposed on the steering column by the strap. A controller produces a signal of a magnitude indicative of an amount of resistance needed to be imposed on the steering column by the strap to better protect from injury a driver seated behind the steering column at the time of the collision. An actuator receives the signal and actuates the anvil to adjust the amount of resistance imposed by the strap in accordance with the magnitude of the signal.

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.

Abstract: The lower bracket assembly for a vehicle steering column includes a lower column support bracket with a central passage. A lower bearing adapter slides into the central passage from the rear. A pair of energy absorption straps engage the column support bracket and the column support bracket and resist further forward movement of the lower bearing adapter. During a collision, the energy absorption straps absorb energy while permitting the lower bearing adapter to move forward and out of the central passage through the column support bracket.
