Abstract
An energy absorbing anchor for securing a child safety seat to a mounting portion of a vehicle and coupling to a tether of the child safety seat is provided. The energy absorbing anchor comprises a bracket including a first end having a tether coupling portion, and a tapered hole having a wide portion adjacent to the first end and a narrow portion opposite to the first end; and a protrusion extending through the tapered hole to secure the bracket to the mounting portion of the vehicle wherein the protrusion is positioned to be adjacent to the wide portion of the tapered hole and wherein the narrow portion of the tapered hole is narrower than a width of the protrusion; wherein, when the bracket is pulled in tension, the protrusion is drawn along a length of the tapered hole towards the narrower portion, thereby deforming a portion of walls of the tapered hole to widen the tapered hole, the walls of tapered hole being configured to increasingly absorb energy as a width of the tapered hole decreases.
