Abstract
An energy absorption device for use in a steering column assembly in a motor vehicle includes a steering column bracket having a groove formed therein. A sheet strap is mounted on the groove in a hooked configuration and has a first end and a second end. An insert is mounted on the first end of the sheet strap. A pop rivet is mounted to the steering column bracket and extends across the groove to prevent the insert from moving. A pin is mounted on the second end of the sheet strap opposite the first end. The pin is adapted to be coupled to a fixed portion of the motor vehicle. The sheet strap unwinds during an impact event thereby absorbing energy.
