Abstract
The tailgate (1) or rear door for a motor vehicle with a rear window includes a single-piece main carrying structure (10) with a peripheral, flexurally resistant frame (11), with an upper transverse beam (12), two lateral longitudinal beams (13, 14) and at least one lower transverse beam (15). The main carrying structure consists of a fibre-reinforced moulding compound (20) with at least two impregnated, integrated continuous-fibre bands (21) and this moulding compound is non-positively connected to the rear window (2) and together with this forms a flexurally resistant structure. Thereby, the continuous-fibre bands (21) in sections are integrated into the frame (11) in an arrangement vertical (v) to the surface (H) of the tailgate, by way of the continuous-fibre bands (21) being arranged vertically to the surface (H) and/or at a vertical distance (d) to the surface (H).
