| 摘要 |
The invention relates to a device for protecting an occupant of a motor vehicle, comprising a steering column (3) which supports a steering shaft (1) and against which a force (F) is applied by said occupant during a collision, whereby the steering column (3) is displaceable with respect to the stress-bearing structure (4) of the vehicle and comprises a first energy-absorbing unit (7, 9) for absorption of energy during said displacement, as well as comprising a sensor for detecting of a condition which indicates that said occupant is restrained by a seatbelt. The invention is characterized in that a second energy-absorbing unit (13, 14, 22) is arranged between the steering column (3) and the stress-bearing structure (4), and in that the sensor is connected to a locking unit (18, 19, 20) which is arranged such that when said condition is detected, it permits displacement of the second energy-absorbing unit (13, 14, 22) with respect to the stress-bearing structure (4), whereby energy is absorbed. By means of the invention, an improved device for protection of occupants of a vehicle is provided where, in particular, an optimal energy-absorption is offered irrespective of whether the driver is wearing his seatbelt.
