If necessary, a rear window glass is carried by the panel 22.
- box 20 and the panel 22 are made of thermoplastic materials and are assembled together by known means, for example by gluing.
- the tailgate 16 may comprise a box 20 made only partly of thermoplastic material.
- pairs of elements arranged symmetrically on the body 14 or the tailgate 16, in particular on the left and right sides of the body 14 or the tailgate 16, are represented by only one of these elements. symmetrical.
- the rear bay 18 of the body is defined in particular by a pair of rear uprights 24 of the body, forming side edges of the bay 18, and a rear cross member 26 of the body, defining also a roof 28 of this box and forming an upper edge of the bay 18.
- the tailgate 16 is hinged to the body 14 by means comprising, in the example described, a pair of hinges 29reliant, on the one hand, the upper edge of the bay 18 formed by the rear cross member 26, and, d on the other hand, an upper edge 16S of the tailgate 16. These hinges 29 materialize a horizontal axis of articulation.
- the assembly 12 also comprises means connecting the body 14 and the tailgate 16, generating an axial thrust assistance to the opening of the tailgate 16.
- These assistance means to the opening of the tailgate 16, which also participate in the damping of the closing movement of the hatch 16, comprise a pair of conventional cylinders 30 respectively left and right.
- Each cylinder 30 is provided with a first end 30A of connection with the body, more particularly with a side edge of the rear bay 18, formed by a post 24, and a second end 30B of connection with the tailgate 16, plus particularly with a side edge 16L of the tailgate, so as to exert, between these two connecting ends 30A, 30B, an axial thrust.
- Each jack 30 is provided with a body 32 in which is axially slidably mounted a rod 34 between positions of minimum and maximum lengths of the jack 30.
- the rod 34 is biased towards the position of maximum length of the jack 30 under the effect of the axial thrust, to assist the opening movement of the tailgate 16.
- the first end 30A of the cylinder is formed by a free end of the body 32 which materializes a pivot point of the jack 30 fixed relative to the body 14.
