A seat for mass transportation vehicles includes a bench portion, a back portion and an elongated impact energy absorbing grabrail extending along the upper edge of the back portion. The grabrail is molded as an integral, one-piece member from a plastic material. The grabrail includes an elongated base member having an aisle end and a wall end. The base member defines a plurality of longitudinally spaced attachment apertures. Suitable fasteners extend through these apertures to secure the grabrail to the upper edge of the back portion of the seat. A rail portion is formed integral with the base portion and extends therefrom. The rail portion includes legs which are joined to the upper surface of the base portion. The grabrail is essentially solid and has a transverse cross section in the shape of a polygon. The grabrail resists cutting by vandals and deflects on impact to absorb energy and compartmentalize passengers in the vehicle.
