Abstract
A preformed element for the interior trim of motor cars compises a shaped base of thermoplastic material produced by injection moulding and having openings, and flat panels carrying a soft covering and applied to the back face of the base in correspondance with the openings. The flat panels are fixed by hot deformation of integral retaining appendages projecting from the back face of the base, or by welding, gluing or similar means.
Claims7
A preformed element for the interior trim of motor cars, which comprises a preformed base of thermoplastic material produced by injection moulding and having at least one opening and integral retaining appendages extending therefrom in the region adjacent said at least one opening, and at least one flat panel carrying a soft covering and including a peripherally extending flange thereabout, said flange including apertures corresponding in number and position for reception of said integral retaining appendages when said flat panel is applied to the back face of said base so as to be positioned in correspondence with said at least one opening, such that said retaining appendages extend through said correspondingly positioned apertures of said at least one flat panel, and thereby provide means for affixing said at least one flat panel to said flange.
A method for the production of a preformed element for the interior trim of motor cars, which comprises the steps of:
- forming a shaped base having at least one opening, by injection moulding of a thermoplastic material,
- producing at least one flat panel formed by a rigid substrate and by a soft covering applied to the substrate,
- fixing said at least one flat panel to the back face of the base in correspondence with said at least one opening so that the soft covering of said at least one flat panel is disposed within said at least one opening when said flat panel is positioned against the back face of said base,
- providing said base with integral retaining appendages projecting from the back face thereof in the region adjacent said at least one opening,
- providing said rigid substrate of said at least one panel with a peripheral flange, said flange having through-apertures positioned to correspond with the number and placement of said retaining appendages, such that said retaining appendages extend through said corresponding apertures, and
- affixing said at least one flat panel by affixing said retaining appendages to said flange by affixing means.
