<p>The invention relates to automotive engineering, in particular to the design of a rear automobile door. The technical result consists in improving the functionality of a rear automobile door by means of ensuring reliable fixing of the door in any position when one or both parts thereof is/are opened. The device comprises a rear door upper part, which is attached in articulated fashion to the rear part of the automobile body on hinges, and a rear door lower part, which is movably connected to the rear door upper part by a movement mechanism which is equipped with pairs of right and left levers, wherein two pairs of lugs, which are arranged at a different height relative to one another in a pair are fixed statically on the rear door upper part with mirror symmetry with respect to the vertical axis of said rear door upper part; and two vertical guides are mounted on the rear door lower part, each of said vertical guides being equipped with a runner with lugs and rollers; wherein the upper ends of the pairs of levers are connected in articulated fashion to the pairs of lugs on the rear door upper part, and the lower ends of the pairs of levers are connected in articulated fashion to the lugs of the runners; the guides are hollow with a triangular cross section and with rounded corners and a slot on one side; the runners are in the form of a body which is triangular in cross section with rounded corners following the shape of the guides and interact with said guides with the aid of the rollers; the rollers are mounted in the corners of the body of the runner in two rows perpendicular to the opposite side of the body of the runner and protrude beyond the apex thereof; wherein the lugs of the runners are fixed at the edges of the body parallel to the longitudinal axis thereof and with an offset in different directions relative thereto. The upper and/or lower part(s) can be equipped with gas cylinders, springs or an electric motor, and also with locking mechanisms and opening and closing buttons.</p> |
