FR2883517A1 - Dust boot assembly for partially masking gearshift lever of motor vehicle, has ring, made up of base of spring steel wire, partially engaged in groove of base plate and permitting plating of base of dust boot in groove - Google Patents

Abstract

The assembly has a rigid annular base plate with an inner surface (4) and fixation units (5), and a flexible dust boot (6) with a base (7) disposed against the inner surface. The base plate made up of injected plastic material has an annular groove (9) provided on its inner surface. An elastic hog ring (8) made up of a base of a spring steel wire permits plating of the base in the groove. The ring is partially engaged in the groove to assure the maintenance of the boot against the base plate.

Description

The invention relates to a gear lever bellows assembly for

motor vehicle.

  It is known to provide a gear lever bellows assembly for a motor vehicle, intended to at least partially mask said lever and comprising: a rigid annular base comprising means for fixing to a support element, a flexible bellows, in particular based on plastic or leather, whose base is associated with said base, said bellows being associated with said base for example by sewing, gluing or welding.

  Such an association mode has disadvantages in terms of mounting complexity and therefore manufacturing cost.

  The invention therefore aims to provide a simplified and economical manufacturing bellows assembly.

  For this purpose, the invention proposes a set of gear lever bellows for a motor vehicle comprising: a rigid annular base comprising an inner face and means for fixing to a support element of the passenger compartment of the motor vehicle, a bellows flexible base whose base is disposed against said inner face, the base comprising an annular groove provided on its inner face and the assembly further comprising a means for plating said base in said peripheral groove.

  In one embodiment, the plating means is an open elastic ring arranged to engage at least partially in said groove so as to maintain said bellows against said base.

  Other features and advantages of the invention will appear in the description which follows, made with reference to the attached figures in which: Figure 1 is a schematic perspective view of a bellows assembly according to the invention, arranged around FIG. 2 is a diagrammatic representation of an open ring in the constrained (2b) and extended (2a) position; FIG. 3 is a schematic representation in partial section of the lower portion of FIG. set of figure 1. i0

  Referring to Figure 1, there is now described a bellows assembly 1, for at least partially masking a speed lever 2. Said assembly comprises: E a rigid base of substantially annular shape 3 comprising an inner face 4 and means fixing 5 to a support element (not shown) of the passenger compartment of the motor vehicle. Said fixing means comprise, for example, tongues made from material, said tongues being provided with a harpoon at their free end, said harpoon being intended to cooperate with an orifice provided in the support element so as to ensure the fixation of the together to the passenger compartment of a motor vehicle.

  E a flexible bellows 6, for example based on plastic or leather, the base 7 is disposed against said inner face.

  The rigid base 3 has, on its inner face, an annular groove 9, as shown in FIG.

  Said assembly further comprises a plating means 8 of the base 7 in the peripheral groove 9.

  According to the embodiment shown in the figures, the plating means is an elastic open ring (shown in Figures 2 and 3), arranged to allow the plating of said base in the peripheral groove 9. The ring is arranged for s engage at least partially in said groove so as to maintain said bellows against said base.

  The engagement, at least partially, of the ring in the groove 9, ensures an effective maintenance of said bellows against said base.

  According to other embodiments not shown, the plating means 8 can be made in other forms, such as a rigid annular element arranged to fit into force in the annular groove 9, the base 7 being interposed between said rigid element and the throat 9.

  Said base, shown here circular, can have various geometric shapes (square, oval, ...). It can typically be made of injected plastic material, which allows easy integration of said groove and said securing means, by molding.

  FIG. 2 represents an embodiment of the ring in the retracted position, (FIG. 2b), adopted to allow its mounting, for example with a clip-fastener, and in the extended position (FIG. 2a), once introduced into the throat 9. Said ring can be formed based on a spring steel wire shaped to the required dimensions, in order to allow optimal plating of the base 7 in the groove 9.

  FIG. 3 illustrates the mounting of the bellows 6 against the internal face 4 of the base 3. The ring is arranged so as to enable the base 7 to be veneered in the peripheral groove 9 provided on said inner face, said ring engaging at least partially in said groove so as to firmly hold said bellows against said base.
