ABSTRACT:
FIELD OF THE INVENTION
The scope of the invention is that of interior fittings for motor vehicles and, in particular, those associated with car doors.
BACKGROUND OF THE INVENTION
There already exist motor vehicle doors which comprise:
an exterior door panel, typically of sheet metal,
an interior door lining which is fitted to the exterior panel and which covers it at least partially, the panel and the lining together defining, at least locally, a hollow internal space, the lining comprising a carrier panel of rigid plastics material, and
a window, connected to at least one window lifting mechanism which comprises at least one means of support of the window in the region of a lower edge thereof and which is itself fixed to the exterior panel and/or the interior lining, so that the window can be displaced substantially vertically between a first upper position and a second lower position, in which it extends inside the internal space of the door.
With regard to those components, it became apparent that there were problems of stability and poor positioning or displacement of the window inside the door, in particular when the window is slightly curved (as is very often the case at present) and when it is at least partially lowered inside the hollow internal space of the door.
That can, in particular, result in a malfunction of the window or in damage thereto, in particular owing to significant vibrations, which the vehicle (and therefore the window) can undergo, or when the door is closed (whether slammed or not) with its window partially or totally lowered.
SUMMARY OF THE INVENTION
The invention proposes to solve that problem at little cost and with good reliability. To that end, the invention relates to an interior lining for a motor vehicle door, the lining comprising:
a carrier panel of rigid plastics material which is integral with the lining and to which is fixed a window lifting mechanism which is fitted with a window and which comprises a support means for that window which is movable between a first upper position and a second lower position for the displacement of the window,
at least one resilient stop means to limit the lateral displacement of the window in a substantially horizontal direction, the stop means having a free end, and an opposing end which is connected to the carrier panel, wherein the stop means has an open and naturally curved portion which has a contact region with the window, which contact region is arranged with spacing (away) from the free end of the stop means.
“Naturally curved portion” is intended to signify the fact that the shape of that portion is rounded or rolled without any force being applied thereto, in particular a supporting force from the glass on the stop means.
Furthermore, since the stop means is in constant contact with the window, it is adapted to be deformed in a resilient manner and to push away the window by exerting a restoring force which opposes the lateral movements of the window, and this in a direction which is substantially perpendicular to the normal direction of displacement of the window (raising and/or lowering).
In order to limit to the greatest possible extent the lateral movements of the window inside the hollow internal space of the door, and to allow a good guiding of the window, whatever its position inside that space, the resilient stop means can comprise a rigid rod which terminates, at the free end of the stop means, in a resiliently deformable portion which has an open curved portion which is in the shape of a hook, against which the surface of the window presses, that curved shape having, in the region of its contact region with the window, inverted inclines for guiding the window substantially according to the two, lowering and raising, movements thereof
In accordance with an alternative, the resilient stop means can comprise a rigid rod which terminates, at the free end of the stop means, in a resiliently deformable portion which has two successive inverted inflexions, giving it substantially the shape of a flattened “S”.
According to a complementary aspect, the carrier panel preferably incorporates the resilient stop means which is then in the form of a rib, with which it is moulded as one component.
The invention also relates to a motor vehicle door comprising:
an exterior door panel, typically of sheet metal,
an interior door lining which is fitted to the exterior panel and which covers it at least partially, the exterior panel and the interior lining together defining, at least locally, a hollow internal space, the lining comprising a carrier panel of rigid plastics material, and
a window which is connected to a window lifting mechanism which comprises a support means for the window in the region of a lower edge thereof and which is itself fixed to the exterior panel and/or to the interior lining, so that the window can be displaced substantially vertically between a first upper position and a second lower position, in which it extends inside the internal space of the door,
the carrier panel being fitted, at an intermediate level, with at least one resilient stop means which cooperates with the window to limit the lateral displacement thereof in a substantially horizontal direction, the stop means having a free end and an opposite end which is connected to the carrier panel,
wherein the stop means has an open, naturally curved portion which has a contact region with the window, which contact region is arranged with spacing from the free end of the stop means.
