Abstract
A door module (1) is adapted to be applied in a sealed manner to the periphery (2) of an inner opening (3) of a box structure (4) of a vehicle door (5) and can support devices such as a window raiser (6). The module (1) comprises a rigid peripheral part (14) composed of a first material having good mechanical properties shaped to be adaptable to the periphery (2) of the opening (3), and a plate (15) composed of a second material connected on its periphery in a sealed manner to the rigid peripheral part (14) and filling the area defined by the latter. The plate (15) may be composed of a cheap material, which reduces the cost of the module while maintaining its mechanical properties on the peripheral part thereof. The devices, in particular the window raiser, are fixed to the rigid peripheral part (14).

Description
Background of the Invention
[0002] The present invention relates to an automobile vehicle door module adapted to be applicable in a sealed manner on the periphery of an inner opening of a box structure of the door, and provided with devices such as a window raiser, latch, internal latch opening handle, which are mounted on a suitably arranged panel.
Brief Summary of the Invention
[0003] An object of the invention is to provide a module having a panel for carrying the devices that costs much less than the panels used up to the present time.
[0004] According to the invention, the door module comprises a rigid peripheral part composed of a first material, shaped to be adaptable to the periphery of the opening of the box structure in a sealed manner, and a plate composed of a second material connected on its periphery in a sealed manner to the rigid peripheral part and filling the area defined by the latter.
[0005] The material of the rigid peripheral part must have satisfactory mechanical properties to perform its function of a sealed support for the devices of the module. On the other hand, the material of the plate connected to the rigid peripheral part may be a cheap, low-quality material much less expensive than that of the rigid peripheral part, which enables substantially reducing the cost price of the panel making up the module.
[0006] In one embodiment of the invention, the rigid peripheral part is formed by a hollow section member or a section member including cross-bracing ribs.
[0007] The plate may be a film onto which the rigid peripheral part is molded.
[0008] Further features and advantages of the invention will be apparent from the following description, with reference to the accompanying drawing, which illustrates an embodiment of the invention by way of a non-limitative example.
Brief Description of the Drawing
[0009] The FIGURE is an exploded perspective view of a vehicle door module according to the invention on the inner side of the door on the opening of which the module must be applied.
Detailed Description of the Preferred Embodiment
[0010] The module 1 illustrated in the single FIGURE is adapted to be applicable in a sealed manner on the periphery 2 of an inner opening 3 of a box structure 4 of a vehicle door 5.
[0011] This module 1 may be provided with devices such as a window raiser 6 which is, in the illustrated embodiment, of the so-called “double lift” type having two parallel rails 7 and guiding cables 8, 9 arranged in the form of an X between the rails. A latch 11 and an inner handle 12, for controlling the opening of the latch 11 through the medium of a rod 13, complete the devices. The devices are fixed to the rigid peripheral part 14, because of its mechanical properties, by known means which have not been shown.
[0012] The module 1 comprises a first rigid peripheral part 14 composed of a first material so shaped as to be adaptable to conform to the periphery 2 of the opening 3, and a plate 15 composed of a second material. The plate 15 is connected on its periphery in a sealed manner to the rigid, shaped peripheral part 14 and fills the area defined by the latter. In other words, the plate 15 essentially extends across the entire area framed by the first peripheral part 14.
[0013] The shaped peripheral part 14 is composed of a “high quality” material having good mechanical properties, such as for example a polyamide such as a 6—6 polyamide, a thermoset polyester or a thermosetting polyester polypropylene or a polyphenylene oxide including one with a glass fibre filler. The inner plate 15 preferably is a film onto which the rigid shaped peripheral part 14 is molded.
[0014] The peripheral part 14 may be formed by a hollow section member or may comprise cross-bracing ribs 16 (shown in the cut-away portion). The plate 15 may also be placed in position by injection-molding of a suitable material such as for example polypropylene, polyphenylene or a polyethylene, this process being well known and requiring no description. In the preferred embodiment, the peripheral part 14 and the plate 15 comprise a single continuous unitary structure.
[0015] The preceding description is exemplary rather than limiting in nature. Variations and modifications to the disclosed embodiment may become apparent to those skilled in the art, which do not depart from the essence and spirit of this invention. The scope of legal protection is only limited by the following claims.
Claims
Post-issuance certificates present
The text shown below may not reflect later post-issuance changes.
What is claimed is:
1. A door module for use in sealing a periphery of an inner opening of a door structure, said module comprising:
