Definitions
- Deformable component in particular equipment for a motor vehicle, and method for its production
- the invention relates to a component, in particular an equipment part for the interior of a motor vehicle, comprising a first, hard-elastic or plastically deformable support structure and a second, soft-elastic component which is integrally connected thereto and which seals the support structure provided with recesses, and a method for producing a component of this type, in which the hard-elastic or plastically deformable support structure provided with recesses and the soft-elastic component are preferably molded by injection molding.
- the component designed as a storage compartment for a motor vehicle consists of a trough-like inner part made of a soft plastic, for example of a thermoplastic elastomer, which is surrounded by a hard outer shell which is integrally connected to the inner part. There are U-shaped recesses in the outer shell
- BESTATIGUNGSKOPIE embedded which form latching projections, hard-elastic resilient latching tongues. From the inside of the storage compartment, the recesses are completely covered by the trough-like inner part. A bending deformation of the latching tongue causes the inner part to buckle, which, due to the use of a flexible material, does not result in mechanical damage.
- the inner part is first molded onto a mold core in a cavity that is smaller than the target contour by the wall thickness of the hard component in an injection mold.
- the mold core with the molded-on soft inner part is then inserted into the mold cavity of an enlarged casting mold.
- the gap remaining between the inner part and the mold cavity can now be filled with the hard plastic.
- this procedure has the disadvantage that considerable use of the comparatively expensive soft component is required. It is therefore only suitable for components in which the inner shell has to be completely lined with a soft tub to improve the feel.
- the invention has for its object to provide a sealed component with deformable support structures that can be manufactured with a relatively small proportion of flexible material component with a simple and reliable process.
- the object is achieved according to the invention in that the recesses of the component are essentially filled by the soft-elastic component and are therefore sealed.
- the hard-elastic support structure can have U-shaped recesses which form locking tongues molded into the support structure and, for example, for releasably fastening the component in an overall system.
- the local wall thickness of the soft-elastic component sealingly filling the recess is preferably made smaller, in particular by at least half less than the local width of the recess in question. In this way, the soft-elastic filling of the recess is sufficiently deformable so that the warping required for inserting the locking tongues can be carried out without damage and with little effort.
- the hard-elastic or plastically deformable support structure is designed in a grid-like manner, the flat recesses formed between the grid elements being essentially filled by the soft-elastic component and thus sealed.
- a component has Although there is sufficient basic rigidity, it can deform plastically in the event of a side impact, without the need for an undesirably high deformation force.
- the sealing closure by the soft-elastic component also enables the application of a hard-elastic or plastically deformable support structure and the soft-elastic portion sealingly filling the recesses, covering one side of the foam layer, in particular from a PUR foam, without special measures for closing the recesses during manufacture Foaming process.
- it can advantageously be provided that the foam layer on its lateral system facing the support structure is completely surrounded by a sealing bead made of flexible material which is integrally formed on the support structure. The sealing bead seals the support structure in the foaming tool so that the foam cannot escape from the mold cavity.
- the foam can additionally be laminated with a flat decorative material, in particular a plastic film, a fabric or a leather.
- the method according to the invention for producing the component is characterized in that the recesses are subsequently filled in a sealing manner by injecting a flexible component.
- the soft elastic component can be injected into the recesses at the same time or a time-delayed sealing bead made of a soft elastic component is molded onto the carrier structure with a delay to this process.
- the support structure can subsequently be inserted into a foaming tool and provided with a foam layer at least on one side.
- Foam a flat decorative material is inserted into the foaming tool and then the foam layer is introduced into the space between the decorative material and the support structure.
- a flat decorative material can be laminated onto the foam layer after the foaming process, in particular by gluing.
- Fig. 1 shows an armrest designed according to the invention for a
- Fig. 2 shows the armrest of Fig. 1 in section A-A
- Fig. 3 shows the armrest of Fig. 1 in section B-B
- the armrest 1 shown in the figures consists of a hard-elastic or plastically deformable support structure 2, which can be produced, for example, from a polypropylene (PP) or a PP compound by injection molding.
- the armrest can be detachably connected to a center console 4 indicated in FIG. 2 via a snap-in connection 3.
- the support structure 2 is designed in a lattice-like manner, so that although it basically has sufficient strength for use, it can be deformed elastically or plastically in the event of a side load caused by an accident, for example the impact of a seat occupant placed next to the center console , The local forces acting on the seat occupants can be considerably reduced by this configuration compared to a support structure that is closed over the entire surface.
- the recesses 5.1 formed during the lattice-like formation of the support structure are, as shown in FIG. 2, sealed with a membrane-like, soft-elastic component 6.1. It is therefore possible without further action to insert the sealed support structure 2 into a foaming tool and to comfortably cushion it on the support side for the arm of the seat occupant by foaming a foam cushion 7, for example from a PUR foam.
- the foam cushion 7 is laminated on the support side with a decor 11, for example made of leather, a plastic film or a textile fabric.
- a material for the soft elastic component is, for example, a polyolefinic thermoplastic elastomer (TPE-O) with a hardness of 60 to 80 Shore A.
- TPE-O polyolefinic thermoplastic elastomer
- This material can be easily connected to a carrier structure made of PP, increases its rigidity only slightly and has sufficient strength to withstand the foaming pressure when foaming the foam cushion 7.
- a sealing bead 8 is also injection molded from the same material, which surrounds the support structure completely around the side, which seals the support structure 2 in the foaming tool and prevents the foam from passing over.
- care must be taken to ensure that the air to be displaced from the cavity by the expanding foam can be removed.
- the carrier structure 2 is further provided with a number of U-shaped recesses 5.2, which in the region of the latching connections 3 form latching tongues 10 provided with latching hooks 9.
- the latching tongues 10, although connected in one piece to the support structure 2, are comparatively flexible due to their geometric design, so that the armrest 1 can be latched in the center console 4 with little effort.
- the recesses 5.2 are also closed with a soft-elastic component 6.2, which is preferably injection molded from the same material with the other soft components in one operation.
- the wall thickness d of the flexible component is dimensioned such that it is smaller than the width b of the recess 5.2.
- the wall thickness d is approximately half the width b, so that the flexibility of the tongue 10 is not inadmissibly reduced by the connection of the soft-elastic component.
