To carry out this task, any other systems do not carry all these elements but require several successive assembly phases of each of the positioning and fixing operations of the assembly to the vehicle door even when they use similar accessories but are not members of the housing, so that the disassembly also presents difficulties that can be obtained in order to achieve a better result both in assembly times and in manufacturing costs, in specialization of labor, and a faster disassembly and
simple.

Given the peculiarities of this type of housing, with the manufacture based on a lightweight material in this case plastic, incorporates both the drum for housing brake retainer system as the components that allow perform placement, positioning, centering and preassembled either based on pivots and centering holes, flexible claws and pins, the same to place the retainer on the shell itself as a specific riveting system for fasten the housing, already mounted the brake device, to the support or vehicle door.

With the implementation of this invention, they achieve remarkable improvements in the production process of the carcass, since it incorporates elements that were previously annexed then, with the consequent economy in production costs, as well as the considerable decrease in the times of realization of the assemblies, both in the incorporation of the retainer of brake to the housing as by placing it in the support or vehicle door.

All the stated objectives are taken to the practical since the housing is made in one piece, even with the drum to house the brake retainer as with the corresponding components that serve to make all the positioning, centering, fixing and pre-assembly functions, since It is made of a lightweight material such as plastic.

This housing incorporates, on the one hand, some cylindrical pivots with the outer extremity in the form of a warhead or conical trunk that facilitate rapid insertion and that are symmetrically located in the retainer support plane of brake, but with its axes perpendicular to it.

On the other hand it consists of claws and sideburns flexible with specific design for clamping functions, also located in the support plane of the brake retainer, with enough flexibility to use it quickly and safe, both to incorporate elements into the housing and for the later location of this one. Its placement is with the axes respective perpendicular to the support plane of the brake retainer and distributed on this plane according to the use of them.

There are metal washers with some flexible pins on existing housings in the housing and whose bases, adequately to the washers and with holes for rivet step, have an inclination with respect to the support plane of the housing that with the incorporation of a rivet with the Corresponding support or door is effectively fixed.

It is an objective of the invention of a device for housing assembly of a window regulator drive housing made of lightweight material, in this case in material plastic, which forms a single piece with both the housing cylindrical drum for the brake retainer as with the precise components to perform the placement functions, positioning, fixing and preassembly.

It is another objective of the invention of a mounting device for housing of a drive window lift with washers and flexible pins located on housings with adequate and inclined through hole with respect to support plane of the brake retainer.

It is another objective of the invention of a mounting device for housing of a drive window lift cylindrical pivots with vertical axis to the plane of brake retainer support and ogive or truncated conical in its end to perform centering functions.

It is another objective of the invention of a mounting device for housing of a drive window lift a series of specific design claws to exercise fixing of elements to be incorporated into the housing.

It is another objective of the invention of a mounting device for housing of a drive window lift a series of flexible pins for fixing elements to be incorporated into the housing and with a suitable design for the job  To make.

It is another objective of the invention of a mounting device for housing of a drive window lift a series of flexible claws for fixing the housing, and with special design.

Finally it is another objective of the invention of a mounting device for housing of a drive window lift with embutible pivots placed vertically in the back side of the housing and perpendicular to the drum of brake retainer housing.

All these objectives can be achieved in the practical with a lightweight material housing, as you can be the plastic, including the drum for housing the brake retainer that projects cylindrically on the face rear of the housing and with a correlative height to the measure of the content and forming part of the housing

There are cylindrical pivots of adequate height to its function of being embedded in a fixing phase and are located radially equidistant from each other and their axes perpendicular to the support plane of the brake retainer and in the same back face of the housing.

There are at least three cylindrical pivots with ogival or frustoconical end and placed in the support plane of the brake retainer in a symmetrical way and should have a height adapted to the functional need of the process and placed in the front face of the housing.

It also has at least three pins flexible for proper, fast and secure fixing and located in the same support plane of the housing, so equidistant from each other and located on the front of the Case.

There are at least two claws aligned in parallel each other at the end of the housing that exert a function of fixing together with two other flexible pins located on the opposite part of the housing with respect to the previous ones but in the same front face of the housing.

Washers are incorporated in housings whose flat base has a certain inclination with the support plane of the housing forming a natural angle and graduation appropriate to the application of the washers, together with flexible pins in the housing of each washer, all located in the front face of the housing and in an area of the support plane of the
Case.

The operational form of this mounting device for housing a window regulator drive is carried out, with claim by this invention, with a single piece of lightweight material such as plastic with elements of housing, placement, fixing and pre-assembling that are part housing member.

The housing incorporates a retention system of brake that is housed in the central drum of the same with access by the front face of the housing, as well as the passage of the cable drive that comes out of the brake retainer by two arms that form an angle to each other depending on what is required by the system window regulator

The placement of this brake retention system consists of aligning the cylindrical centering pivots, which are arranged in the support plane of the brake retainer and whose axles they are located perpendicular to the mentioned support plane, with the holes of the brake retainer bracket.

Once the device is centered, the fixing it by coupling its support plate to the flexible pins that are in the support plane of the brake retainer, placed and facing its fixing area towards the interior of the plane, coinciding with the contour perimeter of the retainer bracket plate.

Then the inlay of the pivots located on the rear face of the housing is performed, thereby acting on the flexible pins that are fixing the brake retainer reaffirming the fastening of the
same.

On the front face of the housing are placed some metal washers in housing for this purpose arranged in areas of the retainer support plane. The washers are fixed in their respective accommodation for the action exerted by sideburns flexible paired and arranged diametrically and whose ends They act as springs to maintain the fixing of the washers. The bases of these washer housings are also flat but they have an inclination with respect to the plane of support of the housing so that the washers allow the through introduction of a rivet through a central hole that exists at the base of the housings and which will be used to carry out the preassembly of the housing to the sheet of a support or of a door in an area where the brake retainer support plane should be and finally a power window drive cable, whose connection the rest of the system is done by leaving them from the casing by two tube-shaped steps that form a angle appropriate to the needs of the drive itself.

Made these placements and fixings respective proceed to the placement of the housing assembly with brake retainer on the appropriate support to the location of the device whether it is the door or another type of support that must have the window regulator system. And this is done with the preassembly based on clamps with spring effect that act as clamping jaws fixing the device to the support correspondent.

When it is preassembled, the system goes to riveting the housing to the corresponding fixing bracket for which uses at least one rivet of the rivet that is placed through the base of the housing of a washer, to it, both located on the front face of the housing, and a hole in the support where the housing is to be placed.

Because of its asymmetric placement due to inclined settlement of the washer this rivet reinforces the settlement of the housing on the support and reduces the risks of carcass breakage in the riveting area.

In the case of requiring disassembly, the housing can be released by acting with a drill in the rivets of restraint since its disposition asymmetrically by its inclined conception of placement prevents the rotation of its body being able to free the housing by destroying the rivet.
