A steering system includes a fastening mechanism that makes an upper jacket fastened to be held by a lower jacket. In a fastened state of the fastening mechanism, a first tooth member on the upper jacket side is meshed with a second tooth member on the lower jacket side. The second tooth member is connected to the lower jacket via a guide shaft (connecting member) that is fracturable during a secondary collision. During the secondary collision in an unfastened state of the fastening mechanism, a second engagement portion (driving member) that moves in a column axial direction integrally with the upper jacket abuts on the second tooth member in an unmeshed state to fracture the guide shaft, and deforms an impact absorbing member via the second tooth member to absorb an impact.

A steering column includes an outer jacket that is adjustably secured to a carrier unit and clamped to a telescopically adjustable inner jacket. The outer jacket has a tubular body with a clamping slot extending longitudinally. Opposing side plates disposed alongside the clamping slot extend longitudinally. The side plates are connected to the tubular body and each have a longitudinally-extending elongated hole spaced apart from the tubular body in an outer region that protrudes from the tubular body. A clamping bolt extends through the elongated holes and an opening of the carrier unit. The clamping bolt applies a clamping force to load the side plates. An inner region of each side plate is fixed to the tubular body. A support element is connected to each side plate between the elongated hole and the inner region and is connected to the tubular body in an edge region of the clamping slot.

A locking mechanism for a telescoping steering column includes an energy absorption strap having a plurality of teeth disposed therealong. Also included is a clamp bolt rotatably driven by an adjustment lever. Further included is an actuator body coupled to the clamp bolt and rotated therewith. Yet further included is a first lock cam coupled to the actuator body and engageable with the teeth of the energy absorption strap to lock the telescoping steering column in a first direction. Also included is a second lock cam coupled to the actuator body and engageable with the teeth of the energy absorption strap to lock the telescoping steering column in a second direction different than the first direction.
