摘要： 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.
