• This carriage 30 is intended to slide on the profile 22 during the rotation of the pinion 25, that is to say during the displacement of this pinion 25 on the rack 21.
• the edges 31 of the outer face of the trolley 30, directed towards the outside of the vehicle have a profile complementary to the internal profile of the profile 22.

• This coil spring 40 is preferably of constant stiffness and is substantially continuously prestressed, its preload being maximum when the pinion 25 is positioned at the lower part of the rack 21, as shown in FIG. 3.
• the means for supporting and blocking the plate 10 comprise, for each rack-and-pinion system, a finger 50 carried by the plate 10, as shown in FIGS. 2 and 4.
• the fingers 50 are displaceable by a control member 51 (FIG 2) perpendicular to the longitudinal axis of the vehicle, between a retracted position allowing the plate 10 to move between the different positions and a plateau locking position. 10 in one of these positions.
• Each finger 50 passes through the sleeve 32 of a carriage 30 and opens facing the core 24 of the corresponding section 22.
• This core 24 is pierced with holes 35 distributed at different heights along the length of the profile 22.
• Each orifice 35 corresponds to a raised position of the plate 10 relative to the floor 3 of the trunk 2 of the motor vehicle. In the embodiment shown in FIG. 3, three orifices 35 are provided. Several other orifices 35 may also be provided on the web 24 of the section 22 to provide other intermediate positions. Similarly, the profile 22 may be provided longer to allow a larger scale of deployment to potentially allow the plate 10 to form a rear shelf for the trunk and no longer just a false floor. Thus, in each of the positions corresponding to an orifice 35, the free end of each finger 50 enters the corresponding orifice 35 so as to lock the plate 10 in the chosen position.

• the rear part of the plate 10 cooperates with support elements 60 each formed by a vertical plate provided on each side wall 6 of the box 2.
• Each plate 60 has on its edge facing the front of the vehicle notches 61 which each of these correspond to a position of the plate 10. These notches 61 are offset towards the rear of the vehicle because of the inclination of the profiles 22 toward the rear of the vehicle so that the plate 10 during its upward movement becomes also shifts slightly towards the rear of the vehicle.

• these spiral springs 40 help the rotation of each pinion 25 which facilitates the rise of the plate 10 for the user who does not feel the actual mass of the plate 10.
• Au during this climb the user releases the actuating means of the control member 51 so that under the effect of each compression spring 50, each finger 50 is automatically repositioned against the core 24 of the section 22.
• the user can determine when the height corresponds to a lockable position by the rattling generated when each finger 50 is relaxed in the orifice 35 which faces it.
• the chest 2 is thus divided into two separate compartments.
• the plate 10 can be moved in different positions so as to allow the user to change the volume of each compartment according to the loads or objects to be transported while still having the possibility of pivoting the plate 10 to facilitate the extraction of objects arranged below.
• each spiral spring 40 is always prestressed, the assistance provided by each of these springs 40 is also performed during the descent of the plate 10 which facilitates this descent.

• the plate 10 becomes autonomous and can removed without harming the mechanism, whether for repairs or for space saving.
• the assistance provided by each of the spiral springs 40 allows a user to be able to easily move the platform 10 forming false floor both upwards and downwards to choose a position of this false floor according to the objects to be placed in the chest.
• the necessary handling effort is constant and unctuous and the tray is easily manoeuvrable with one hand.
• the arrangement according to the invention therefore allows easy and easy movement of the false floor and provides easy access to the spare wheel placed below the floor, without having to leave the false floor of the motor vehicle.
