Abstract
The disclosure relates to an energy absorption device for arrangement between a fastening device and a holder, wherein the holder is movable relative to the fastening device when a predetermined impact force is exceeded. The energy absorption device includes a deformable strand for absorbing energy, and a guide device for guiding the strand during the deformation. In order to be able to implement the assembly and/or the production more cost-effectively, the strand and the guide device are formed in one piece.
Claims20
An energy absorption device for arrangement between a fastening device and a holder, wherein the holder is movable relative to the fastening device when a predetermined impact force is exceeded, with a deformable strand for absorbing energy, and with a guide device for guiding the strand during the deformation, wherein the strand and the guide device are designed as a one piece element.
The energy absorption device according to claim the guide device is designed with a tubular and/or rectangular cross section, and wherein a first wall of the guide device forms a first guide section and a second wall of the guide device forms a second guide section, wherein the first and second guide sections are connected to one another by at least one of two side walls of the guide device, and lateral guiding of the strand is implemented by at least one of the two side walls.
A steering device for a vehicle and with a fastening device for fastening to a vehicle carrier or a vehicle body, with a holder for holding a steering column, the holder having at least one connecting section for connection to the fastening device, and with at least one energy absorption device which has a deformable strand for absorbing energy and a guide device for guiding the strand during a deformation, wherein the strand and the guide device are formed in one piece.
A method for producing an energy absorption device, wherein the energy absorption device is formed in one piece from a single semi-finished product and/or sheet metal element.
