A steering column is provided column including a bracket adapted to enable the steering column to move as desired by an operator and a clamping system adjacent to the bracket. The clamping system includes a threaded member. A threaded clamping stud extends through the bracket. The threaded clamping stud is selectively coupled to the threaded member of the clamping device. A transmission is coupled to the threaded member. A motor is coupled to the transmission. The motor is operable to drive the transmission to rotate the threaded member in a first position to unclamp the bracket to enable the steering column to move based on receipt of an input from the operator.

Power release and locking adjustable steering column apparatus and method

A vehicle steering assembly includes a mounting plate having a slot and a raised contact surface adjacent to at least part of the slot and a bracket coupled to the mounting plate, adapted to support at least a portion of a steering column. A coupler extends through the slot, and has a head overlying at least a portion of the contact surface, and engages with the bracket to retain the position of the steering column mount relative to the bracket. The combined thickness of all members between the head and the connecting portion is greater when the head overlies the contact surface than when the head is not overlying the contact surface. A greater clamping force is applied by the coupler to all members between the head and the connecting portion when the head overlies the contact surface than when the head is not overlying the contact surface.

Energy absorbing support for a vehicle steering assembly

A vehicle steering assembly includes a steering column having a forward section and a rearward section movable relative to the forward section, a mounting plate adapted to be carried by the vehicle and a bracket releasably coupled to the mounting plate, and operably coupled to the rearward section of the steering column for movement therewith. The assembly also includes a stationary reaction surface disposed adjacent to the rearward section of the steering column and adapted to be engaged by the steering column during at least some events wherein the rearward section is displaced relative to the forward section. This maintains the position of a reaction force on the steering column during movement of the rearward section of the steering column, which provides a decreasing reaction force on the steering column.

Collapsible steering assembly with a stationary reaction surface

A vehicle steering assembly with a movable steering column includes a mounting plate carried by the vehicle, a bracket supporting a portion of the steering column, movable with the steering column, and coupled to the mounting plate, a bend mandrel, and a bend strap operably associated with the bracket for movement with the bracket. The bend strap has a pair of legs on opposed sides of the bend mandrel and a bight interconnecting the legs and arranged so that upon movement of the bracket relative to the mounting plate the bend strap engages the bend mandrel and one leg is progressively deformed about the mandrel to absorb energy from the moving bracket and steering column. A portion of the leg progressively deformed about the mandrel upon movement of the bracket engages a reaction surface defined by at least one of the mounting plate or the bracket.
