Embodiments described herein relate to an end part for a cross member for a vehicle seat, a cross member for a vehicle seat comprising at least one end part, and a vehicle seat comprising at least one such cross member. The end part has a first portion with an impact receiving surface adapted to receive an impact during a side collision. The cross member has a longitudinal center line. A center point of the impact receiving surface is offset with respect to the longitudinal center line so as to bend the cross member in a predetermined direction during the side collision. The present invention provides for a simple way to modify a cross member, or to provide a cross member with additional functionality and increased safety properties.
