ABSTRACT:
An infinitely adjustable manual control for a lengthwise adjustable automotive steering column of the type having a stationary outer member and an inner tubular member slidable telescopically in the outer member. The manual control includes a housing on the outer member, a clutch element mounted on the housing for radial and lateral shiftable movement, and rack teeth on the clutch element and on the inner tubular member. In a lowered position of the clutch element, the rack teeth mesh to immobilize the inner tubular member relative to the outer member. In a raised position of the clutch element, the rack teeth are disengaged. The rack teeth are oriented at an angle to the longitudinal centerline of the steering column so that the lateral movement of the clutch element in the housing effects longitudinal movement between the rack teeth to assure mesh in all relative positions of the inner and outer members. An actuator and a pair of side bars on the housing releasably secure the clutch element in its lowered position. A flexible cable controlled by the driver operates the actuator to release the clutch element for movement to the raised position when lengthwise adjustment is desired.
