Roll bar

A rollbar for an open sports car which extends over the width of the vehicle, having a basic shell body which follows the rollbar shape and consists of molded two-dimensional material with longitudinal ribbings which are alternately raised toward the exterior and interior side of the rollbar. The rollbar shell is integrally formed from a pressed molding of fibrous composite plastic or metallic material and can include stiffening inserts which extend over at least part of the longitudinal extrusion of the shell. An anti-abrasion material can be integrally connected or embedded into the surface of the shell. The rollbar is light weight, optimally designed for individual types of loads and can be integrated into the car body in an esthetically appearing manner.
