Description

The present invention relates to a stop allowing limit the transverse movement of a window that can slide in the casing of a swivel door of a motor vehicle.

On current motor vehicles, closing of each front or rear door with the occupant window its low position in the door casing causes a displacement by inertia of the glass in the direction transverse towards the inside of the vehicle, resulting in by an unpleasant sound of snapping at the closing of the door.

To eliminate this click noise, a solution is to use foam adhesive in the box of the door in order to limit the transverse movement of the sliding window.

However, this known solution has for disadvantages of being difficult to set up in series and lose its effectiveness over time because of the aging of the foam.

The present invention aims to eliminate the disadvantages above by proposing a stop allowing limit the transverse movement of a window that can slide in the casing of a swivel door of a vehicle when closing the door during which the window occupies a low position, and which is characterized by comprising a block in one elastomer material integral with a sole attached to the door lining delimiting the casing thereof way that the elastomer block is located in the box near the glass, part of which is internal can come to bear on the block during the closing the door without contacting the lining of door.

According to a preferred embodiment, the sole of elastomer block support is attached to the liner of door by a box-shaped element of a stop of door of the revolving door.

Advantageously, the door stop is of the type comprising a retaining arm which is articulated to a end to an upright or pillar of the vehicle body and engaging in the door box through of an opening of the door liner, the arm of holding having at its opposite free end housed in the box a stop stop of the element shaped housing that is removably attached with the sole of support of the elastomer block to the door liner by fastening means, such as screws or studs, the retaining arm freely traversing the sole of support of the elastomer block and the element shaped housing.

The support sole of the elastomer block is sandwiched between the door liner and a face plane of the box-shaped element of the shutdown of door and includes piercing holes means of fastening to the door liner.

The sole includes an angled tab substantially parallel to the sliding window and to which is fixed the elastomer block having the shape of a rectangular parallelepiped extending vertically and substantially parallel to the glass or a curved shape extending vertically opposite the window.

The sole is a rigid metal plate of relatively small thickness preferably about 1mm.

The sole includes a central window Rectangular passage of the retaining arm.

The invention will be better understood, and other objects, features, details and advantages thereof will appear more clearly in the explanatory description which follows, with reference to the appended diagrammatic drawings given solely by way of example, illustrating a method of embodiment of the invention and in which:

• Figure 1 is a horizontal sectional view of a right rear door portion of a motor vehicle and showing a door stop which is associated with the stop according to the invention;
• Figure 2 is a perspective view along the arrow II of Figure 1;
• Figure 3 is a perspective view along the arrow III of Figure 1;

• Figure 5 is a perspective view of the door stop which is fixed the stop of the invention;
• Figure 6 is a perspective view of the door stop and the abutment of the invention along the arrow VI of Figure 1; and
• Figure 7 is an alternative embodiment of an elastomeric block of the abutment.

Referring to the figures, reference numeral 1 designates for example a right rear swivel door of a motor vehicle.

The door 1 is pivotally mounted relative to the body 2 of the vehicle on articulation hinges (not shown) with a substantially vertical axis 3 for allow the opening of the door 1 around this axis in the direction indicated by the arrow F in Figure 1 from of the closed position of this door shown in this Fig.

The door 1 comprises a window 4 mounted sliding in the door box delimited by the lining of door or hinge reinforcement 5, an inner panel 6 of glass window support 4 and outer panel the sheet metal of the door 1.

A door stop 7 for the revolving door 1 allows to automatically hold the door 1 to its open position.

The door stop 7 comprises in the present case a retaining arm 8, one end of which is fixed so articulated to the amount or pillar of the bodywork of the vehicle via a clevis support 9 of the vertical pivot axis 10 of the retaining arm 8.

The retaining arm 8 passes through an opening 11 of the door liner 5 and extends into the box of the door 1 with its free end housed in this box between the panel 6 and the window 4.

The free end of the retaining arm 8 has a stopper 12 for retaining the door 1 to its open position as will be seen below.

The door stop 7 further comprises a piece of form of housing 13 through which passes freely retaining arm 8 and which is attached to the lining of door 5 by fixing screws 14, but which can be replaced by studs, anchored through the corresponding flat wall of the door liner 5 of way that the internal opening of the housing 13 allowing the free passage of the arm 8 is coaxial with the opening 11 of the door liner 5.

When the door 1 occupies its position totally open, represented in phantom in FIG. the end of the housing 13 is brought to bear on the stop stop 12 of the arm 8 via a elastomer sleeve 15 housed in the stopper 12 in cup shape so as to hold the door to this opening position.

To limit the transverse movement of the window 4 towards the passenger compartment of the vehicle when closing the door 1 during which the window 4 occupies its position low, a block 16 of an elastomeric material is integral of a soleplate 17 which is fixed to the flat wall of the door liner 5 being sandwiched between the housing 13 of the door stop 7 and this wall.

The sole 17 is constituted by a flat plate Rigid rectangular shape rounded at its ends and relatively thin, for example about 1 mm. This plate has two holes 18 to its ends ensuring the passage of two screws of fastening 14 of the housing 13 to the corresponding wall of door liner 5. The sole 17 further comprises a rectangular central window 19 allowing free passage of the retaining arm 8 of the door stop 7.

The elastomer block 16 is attached to the sole 17 by means of a right-angled bracket 20 on one side of the sole 17. Block 16 may have a substantially rectangular parallelepiped shape extending perpendicular to the sole and parallel to its longitudinal axis. Alternatively, the block 16 may be curved in shape as shown in FIG. figure 7.

In the up position of the sole 17 to the lining 5, the elastomer block 16 extends substantially vertically and parallel to the window 4 nearby from the face of the latter turned towards the cockpit of vehicle so that when closing the door 1 with the window 4 in the down position, the latter come to bear on the elastomer block 16 without entering in contact with the door liner 5 or any other sheet metal element located in the environment of the window 4. In this way, we avoid any noise of slamming unpleasant to close the door 1. In the case of the variant of FIG. 7, the curved shape of the block elastomer 16 extending vertically opposite the window 4, facilitates the engagement and the exit of the window 4.

The elastomer block 16 is advantageously fixed by snapping into the end of the curved tab 20, but can be attached thereto by adhesion.

The clearance j between the window 4 and the elastomer block 16 is relatively small, for example is about 5mm.

The assembly of the whole composed of the block elastomer 16 and the soleplate 17 is extremely easy since it is sufficient to preposition the sole 17 on the fixing screw 14 of the housing 13 of the door stop 7 and to fix the screws 14 to the corresponding flat wall of the door liner 5 so as to trap the sole 17 between the housing 13 and this wall until that the sole 17 is blocked by tightening the screws 14.

Thus, the stop 16 is mounted at the same time as the door stop 7.

The hardness of the elastomer material of block 16 will be chosen to take account of the effect desired damping for the window 4.

As represented in particular in FIG. window 19 of the sole 17 can be opened on one side to allow the mounting of the sole 17 laterally at the arm 8 until the screws 14 are engaged at through respective holes 18 of the sole 17 for the prepositioning of the latter.

The sole 17 is represented as being symmetrical about its longitudinal axis and can include a keying means for mounting correct block forming block 16 relative to the window 4.

The limit stop of the transverse clearance of the glass 4 can thus be easily and quickly mounted in the door box with the door stop without modification of structure of this box.
