Description

The invention relates to an adjustable convertible top compartment floor for a motor vehicle with a folding or folding top, having the features specified in the preamble of claim 1.Such a top compartment floor is formed in DE 101 37 048 A1 by a covering element made of plastic which, together with a fabric part or a dimensionally rigid part, forms a separating arrangement which separates a variable rear luggage compartment from a receiving space into which the folding or folding top is to be introduced folded together in a low position of the covering element. The convertible top compartment floor is complicated to produce with expensive tools, requires a larger installation space and, despite being produced from plastic, still has a relatively high weight. The expensive production results in a correspondingly high cost of parts.Furthermore, DE 10 2004 027778 _A1 shows a device for variably separating a trunk from a rear storage space for a retractable top of a convertible top, having a separating element which is adjustable between a lower position and an upper position. The separating element is designed as a plastic molded part, optionally reinforced with glass fibers.The object of the invention is to specify an adjustable convertible top compartment floor for a motor vehicle with a folding or folding top having the features in the preamble of patent claim 1, which is simpler to produce and has a lower weight.This object is achieved by the features in claim 1. Advantageous embodiments of the invention can be found in the dependent claims.Since the adjustable convertible top compartment base is a press-molded part having an inner honeycomb structure and the honeycomb structure has a plurality of cavities which are partially or completely surrounded by walls of the honeycomb structure, the convertible top compartment base has a low weight and can be produced at low cost using a simple pressing method. The convertible top compartment floor can have, for example, a layer structure in which the honeycomb structure is arranged on the inside and a composite layer made of glass or glass fibers and the plastic polypropylene is arranged directly or after at least one intermediate layer, and a nonwoven layer is optionally applied to the honeycomb structure or optionally to the composite layer directly or after at least one intermediate layer. characterized in that the hollow spaces of the honeycomb structure are completely or partially filled by a material. The cavities of the honeycomb structure can be filled with a material, for example with a consolidated foam of the plastic PUR. The convertible top compartment floor has a long service life and can cause no or hardly any noise in the event of a vibrating load, for example when driving over unevenness of the floor.An exemplary embodiment of the invention is explained in more detail below with reference to a drawing with a single figure, which shows the adjustable convertible top compartment floor in a simplified side view.The convertible top compartment floor 1 shown in a simplified side view in the single figure is arranged in a rear convertible top compartment 2 of a motor vehicle with a folding or folding top so as to be height-adjustable between the vertical position shown by a broken outline and the low position shown by a continuous outline. In the low position of the top compartment floor, the folding or folding top can be introduced into the rear top compartment 2 and deposited on the top side of the top compartment floor in a folded manner. Of the folding or folding top, only one part 3 is shown in the figure, which can be a rear, middle or front part when the folding or folding top is closed.In each case one lateral pivot lever 4, which are arranged symmetrically opposite the vehicle center, is articulated on the body 6 of the motor vehicle, on the one hand, such that it can be pivoted about a vehicle transverse axis 5, and on the other hand, such that it can be pivoted about a vehicle transverse axis 7, on a front lateral region of the convertible top compartment floor 1. In the low position, the convertible top compartment floor is held fixed relative to the vehicle body 6 by a lower support device 8 and in the high position by an upper support device 9.The support devices 8, 9 have components arranged on the body 6 of the motor vehicle and on the top compartment floor 1. The components arranged on the body 6 are formed in the exemplary embodiment by a bolt 10, 11 each, which has a round cross section.At its side regions, the convertible top compartment floor 1 is connected to a side wall 12, 13 in each case, which projects approximately vertically downward from the convertible top compartment floor 1 and runs approximately in the longitudinal direction of the vehicle.The components of the lower and upper support device 8, 9 assigned to the convertible top compartment floor 1 are arranged on each side wall 12, 13 of the convertible top compartment floor 1 and each have a recess 14 open at the bottom in a support part 15 connected to the side wall 12, 13.In addition, these components have an elastic clamping element which is arranged on the support part 15 in the region of the recess 14 and is formed by an annular spring 16 which is radially open in the lower circumferential region. The annular spring 16 is provided on its edge regions adjoining the radial opening with inlet slopes 17, 18 which, when the convertible top compartment base 1 and thus the annular spring 16 approach the relevant bolts 10 or 11, facilitate a radial entry of the bolts 10 or 11 into the interior enclosed by the annular spring 16. In this case, the annular spring 16 expands radially elastically for a short time until the annular spring 16 surrounds the bolt 10 or 11 over a relatively large circumferential region and the convertible top compartment base 1, which is adjusted into the low position or high position, is thereby retained in a force-fitting manner on the bolt 10 or 11 via its side walls 12, 13 or support parts 15 in each case in the vertical direction with respect to an upward adjusting movement.The wall regions of the recess 14 can, in the low position and in the high position, in cooperation with the respective bolt 10 or 11, limit or prevent possibly small elastic displacement movements of the elastic ring springs 16 and thus of the convertible top compartment floor 1 in the vehicle longitudinal direction and / or downward during the driving operation of the motor vehicle.In the exemplary embodiment, the pivot levers 4 arranged laterally symmetrically opposite one another are connected via a transverse strut 19 which is curved somewhat upwards in the transverse direction of the vehicle and is in each case articulated laterally on the front region of the convertible top compartment floor 1 such that it can be pivoted about the transverse axis 7 of the vehicle. The cross strut 19 and the two lateral pivot levers 4 form a U-shaped frame which is produced from a tube.In the low position of the convertible top compartment floor 1, the pivot levers 4 arranged laterally symmetrically opposite are arranged substantially in front of the convertible top compartment floor 1. In addition, in a side view, the pivot levers 4 are arranged together with the convertible top compartment base 1 in an obtuse angle in a V-shaped manner directed upwards.In the vertical position of the convertible top compartment floor 1, the pivot levers 4 are arranged substantially below the convertible top compartment floor 1. In addition, in a side view, the pivot levers are arranged together with the convertible top compartment base 1 directed upwards at an acute angle.The bolt 11 forming a component part fixed to the vehicle body of the upper support device 9 is arranged below the vehicle transverse axis 5 of the pivot lever 4 fixed to the vehicle body in the height direction and behind the vehicle transverse axis 5 of the pivot lever 4 fixed to the vehicle body in the longitudinal direction. The bolt 10 forming a component of the lower support device 8 which is fixed to the vehicle body is arranged below the bolt 11 in the height direction and behind the bolt 11 of the upper support device 9 in the vehicle longitudinal direction.The convertible top compartment floor 1 is loaded into the vertical position by the prestressing force of a spring element acting on at least one pivot lever 4. The prestressing force of the spring element is not sufficient to automatically release the convertible top compartment floor 1 from the lower support device 8 or from the upper support device 9.In the rear region of the convertible top compartment floor 1, a handle 20 is arranged, by means of which the convertible top compartment floor 1 can be respectively manually released from the bolt 10 of the lower support device 8 and from the bolt 11 of the upper support device 9 and can be alternately adjusted into the vertical position or into the low position. In this case, the respective bolt 10 or 11 exits the interior of the ring spring 16 at a predetermined manual force acting upward in the vertical direction on the handle 20, wherein the ring spring 16 expands elastically for a short time.In the low position of the convertible top compartment floor 1, the folding or folding top can be introduced into the rear convertible top compartment 2 and placed on the top side of the convertible top compartment floor 1 in a folded manner. If the folding or folding top is closed, the top compartment floor 1 can be adjusted manually via the handle 20 into its vertical position, in which a rear luggage compartment 21 or residual luggage compartment is enlarged and can thus accommodate larger or further pieces of luggage.The adjustable convertible top compartment floor can be held firmly in a force-fitting manner in the vertical position and in the low position in different ways with respect to an upward displacement movement. The convertible top compartment floor can also be connected in an articulated manner to a single pivot lever. When using bolts, it is not necessary for them to have a circular cross section. Instead of the bolts, other structural components fixed to the vehicle body can also be used for the lower and upper support device. The components arranged for the lower and upper support device on the one hand on the body and on the other hand on the convertible top compartment floor can also be provided in each case on the other part, on the convertible top compartment floor or on the body.According to FIG. 2, the convertible top compartment base 1 is a press-molded part which, in the exemplary embodiment, has a layer structure in which a honeycomb structure, which is for example 10 mm thick, made of a paper honeycomb 22 is arranged on the inside and, on both sides, directly or after at least one intermediate layer, a composite layer 23 made of glass or glass fibers or polypropylene, for example having a mass of 1000 grams per m 2 is arranged thereon, and, in each case, directly or after at least one intermediate layer, a flat needle fleece 24 having, for example, a mass of 350 grams per m 2 is arranged thereon. Such a convertible top compartment floor 1 is light in weight, inexpensive to manufacture, and durable over a long service life. With such a layered structure, the convertible top compartment floor 1 also has a high strength with respect to oscillating loads and has an acoustically damping effect.The inner honeycomb structure may be formed by a paper honeycomb or plastic honeycomb or metal honeycomb or a solidified foam of, for example, the plastic PUR. The hollow spaces of the honeycomb structure can be completely or partially filled with a material. For example, the cavities of the honeycomb structure can be foamed with a foam made of the plastic PUR. At least on one side of the honeycomb structure, a composite layer, for example made of glass or glass fibers and a plastic, for example polypropylene, or another material, can be arranged directly or after at least one intermediate layer. On the honeycomb structure or optionally on the composite layer, a nonwoven layer can be arranged directly or after at least one intermediate layer, which is, for example, a needle-punched nonwoven or flat needle-punched nonwoven. Likewise, the nonwoven layer can be omitted or replaced by a layer of another material, for example of tuft or dilour, a needle felt. The convertible top compartment floor can have an identical layer structure with possibly different layer thicknesses or a different layer structure from the inside in the direction of its flat top side and underside. The honeycomb structure or paper honeycomb can have a thickness of between approximately 2 and 20 mm, for example. When using the composite layer, it can be manufactured, for example, with a thickness between about 0.5 to 4 mm and / or a mass between 500 to 3000 grams per m2. When the nonwoven layer is used, it may have a thickness of between about 0.5 to 2 mm and / or a mass of between 150 to 1000 grams per m2. Changes are possible and can be predetermined by a person skilled in the art.
