Patent ID: 7607696

Claim:
An adjustable steering column for a motor vehicle comprising: a setting unit displaceable into at least one displacement direction for setting the position of the steering column, a holding unit nondisplaceable into the at least one displacement direction, a securement device, in an opened state of which the setting unit is displaceable with respect to the holding unit for setting a position of the steering column and in a closed state of which the setting unit is secured in position by the securement device, and a crash blocking device displaceable between a passive state, in which the setting unit is displaceable with respect to the holding unit in the opened state of the securement device for setting the position of the steering column, and an active state, in which the crash blocking device raises an additional holding force against a displacement of the setting unit with respect to the holding unit in at least one displacement direction, wherein the crash blocking device has one of a first configuration and a second configuration, the crash blocking device having the first configuration comprises at least one blocking element with at least two blocking noses, a plate part being located between the at least two blocking noses, and in the active state of the crash blocking device, the at least two blocking noses are in contact on opposite sides of the plate part, and wherein either the blocking element is connected with the holding unit such that it is nonshiftable into the displacement direction in which the blocking element is effective and the plate part is connected with the setting unit nonshiftable into this displacement direction, or the blocking element is connected with the setting unit nonshiftable into the displacement direction in which the blocking element is effective and the plate part is connected with the holding unit nonshiftable into this displacement direction, and the crash blocking device having the second configuration comprises at least one blocking element with at least two blocking noses, two plate parts in contact with one another being located between the at least two blocking noses, and in the active state of the crash blocking device, the at least two blocking noses are in contact with the surfaces, facing away from one another, of the two plate parts, and wherein one of the two plate parts is connected with the holding unit such that it is nonshiftable into the displacement direction in which the blocking element is effective, and the other of the two plate parts is connected with the setting unit such that it is nonshiftable into this displacement direction.
