Abstract:
A rail profile formed by two curved shaped parts, with two connection zones (1) situated opposite and spaced to each other and having an essentially C-shaped cross-section, each of the connection zones (1) having two side walls (2) running approximately parallel to each other, whereby each side wall (2) extending from a rear wall (4) and free end zones (5) with a curvature with webs (6) running essentially parallel to the side walls (2), wherein the two rear walls (4) of each connection zone (1) are joined to each other by connection walls (7) each running essentially parallel to the side walls (2) and wherein the rear wall (4) exhibits an essentially V-shaped cross-section with a base angle (&bgr;) corresponding to the free end (5) that is smaller than 180Â°, wherein two curved shaped parts are bonded together along two vertical lines (3) of the rear wall (4) formed by the base angle (&bgr;) and wherein the two curved parts are bonded materially with each other, wherein the connection walls (7) are spaced to each other forming a box-like middle part of the rail profile (1).
