FR2749889A1 - SUN VISOR SUPPORT HOOK - Google Patents

Abstract

The invention relates to a sun visor support hook for hooking a rod (4) of the sun visor. It comprises a body (6) and a hook nose (12) which defines, with the wall of the body (6) a housing (3). A flexible tongue (14) is formed in this wall. This tongue (14) decreases the height of the passage to the housing (3), when it is not subjected to any constraint. This allows the hook to be pre-assembled on the sun visor. A cover (22) has a stopper plate (30) for placing the tab (14) in a normal position of use. The cover (22) comprises a tenon (33) which fits in a mortise and which separates the latching tabs (10, 11) formed on the body (6) and serving for the snap-fastening of the hook on the vehicle roof .

Description

1 2749889

  The present invention relates to the field of equipment for

  motor vehicles and more specifically a bumper support hook

  Sun. A sun visor is mounted on the roof of the vehicle by means of a bent arm which allows the sun visor to pivot, on the one hand, around a substantially horizontal axis parallel to an edge of the sun visor and, d on the other hand, around a substantially vertical lateral axis. The sun visor comprises, in alignment with the horizontal pivot axis, a rod which can be hung on a support hook fixed to the roof of the vehicle at

  near the windscreen, in the middle of the vehicle.

  In normal use, the sun visor is supported at its two ends, on the one hand, by the bent arm and, on the other hand, by the support hook, and it can be folded down towards the windshield and towards the pavilion by pivoting. When you want to bring the sun visor to a side window, unhook it from the support hook and rotate it around the axis

vertical of the bent arm.

  In general, the support hook and the sun visor are delivered

  separately and mounted independently of each other on the vehicle.

  The object of the present invention is to provide a support hook which can be pre-assembled in the workshop on the sun visor, which prevents the sun visor from hanging before the final assembly, which can be fixed to the roof without taking the sun visor off , and which allows mounting

  intermediate on the headlining.

  The invention therefore relates to a sun visor support hook, intended to be fixed to the roof of a motor vehicle to serve for the attachment of a rod fitted to a sun visor pivotally mounted on said roof, said hook comprising a body capable of being fixed to said roof by fixing means, a hook beak formed on said body and extending towards the front of the hook, said hook beak delimiting with the wall of said body situated opposite said hook beak a housing capable of receiving said sun visor rod and accessible by a passage opening towards the front of said hook, the sun visor rod being able to be introduced into said housing or withdrawn from said housing by exerting on it

  a force perpendicular to the plane of the passage.

  According to the invention, this hook is characterized in that the wall of the body located opposite the hook beak has a flexible tongue

2 2749889

  formed in said body and which extends towards the rear of the hook, this tongue reducing the height h of the passage, when it is not subjected to any stress, and being elastically deformable to allow the introduction of the rod into the housing and preventing its removal, when the tongue is not subject to any other constraint, and by the fact that means are provided for putting said tongue in a normal position of use, position in which the sun visor rod can be introduced into the housing or extracted from said housing by exerting on it a force perpendicular to the plane

of the passage.

  Advantageously, the means for putting the tongue in the normal position of use comprise a stop plate capable of pressing on a rear part of the tongue, this stop plate being formed on a cover which fits in a cavity formed in the part

back of the body.

  The cover comprises a tenon capable of sliding in a notch formed in the rear part of the tongue and of being housed in a mortise formed in said body, said tenon having clip means cooperating with the tabs of the tongue arranged on each side of the 'notch. The means for fixing the body to the roof comprise two latching tabs which are formed on the upper face of the body and which are capable of snapping onto the sheet metal of the roof. The mortise opens out between the two lugs and the tenon spreads the latching lugs, when the stop plate keeps the tongue in the normal position

of use.

  Thanks to this arrangement, the support hook can be pre-assembled on the sun visor rod. The elastic force of the tongue firmly holds the rod in its housing. The cover can also be pre-mounted on the support hook, the means for clipping the post with the tabs of the tongue preventing its extraction from the mortise. In this situation, the latching tabs of the body are not spaced apart by the lug, the hook supporting the sun visor can then be positioned on the sheet metal of the roof. By pushing the post further into the mortise, the latching legs move apart and immobilize the hook on the sheet, while the stop plate presses on the end part of the tongue and puts the latter in the

  normal hook use position.

  Other advantages and features of the invention will become apparent from the

  reading of the following description given by way of example and with reference to

  attached drawings in which: Figure 1 is a section of a support hook according to the invention, taken along a vertical plane; Figure 2 is a side view of a cover fitting on the hook of the support shown in Figure 1; Figure 3 is a front view of the cover of Figure 1; Figure 4 is a cross section of a support hook in the pre-assembled state and fitted with its cover; during the assembly phase on a vehicle roof; Figure 5 shows in detail the position of the cover and the legs

  during the mounting phase on the roof of a vehicle.

  The drawing shows a support hook 1 intended to be mounted on a sheet 2 of a roof of a motor vehicle to receive in a generally cylindrical housing the rod 4 of a sun visor not shown in the drawing. The housing 3 has a passage 5 towards the front of the support hook 1 which has a height h slightly less than the diameter of the rod 4, so that the latter can be forced into the housing 3 or extracted from this housing 3 in exerting on the rod 4 or the sun visor a force

  F substantially perpendicular to the plane of the passage 5.

  The support hook 1, made of a plastic material by molding or injection, comprises a body 6 which has, on its upper face 7, a recess 8 for receiving a headliner 9 and two latching tabs 10, 11 for the fixing hook 1 in a hole

formed in the sheet metal of the pavilion.

  On the lower part of the hook 1 is formed a hook beak 12 which extends towards the front of the hook 1, that is to say towards the interior of the vehicle, in a direction substantially parallel to the upper face 7 This hook beak 12 delimits the lower zone of the housing 3. The upper zone of the housing 3 is delimited in part by the rigid wall of the body 6 and in its middle zone by a flexible tongue 14 formed in the body 6, which s extends from a front zone 15 of the body 6 towards the rear of the hook

support 1.

  This tongue 14 has a convex surface 16 in the region of the passage 5, and an end portion 17 which has a delimited cut 18

4 2749889

  by two end tabs 19 and 20. The end portion 17 extends behind the housing 3 in a cavity 21 intended to receive a cover 22

  whose description will be given later in this memo.

  The bottom of the cavity 21 is delimited by a wall 23 into which opens a mortise 24 formed in the body 6. This mortise 24 also opens into the space 25 which separates the two legs

10 and 11.

  As seen in Figure 1, the end portion 17 of the flexible tongue 14 is substantially parallel to the upper face 7 of the hook 1, when the tongue 14 is not subjected to any stress, and the distance separating the convex surface 16 and the hook spout 12 is significantly less than the normal height h of the passage 5. However, due to the flexibility of the tongue 14 which can pivot around the front zone 15 if one

  exerts on it a force, it is possible to engage the rod 4 in the housing 3.

  On the other hand, after the introduction of the rod 4 into the housing 3, as shown in solid lines in FIG. 1, the tongue returns to its initial position without stress, and it is impossible to remove the rod 4 from the housing 3 , due to the significant decrease in the height of the passage 5 between the surface

convex 16 and hook spout 12.

  In this same Figure 1, there is shown in dotted lines the position of use of the tongue 14 which allows a normal introduction of the rod 4 into the housing 3 and a normal extraction of the rod 4 from the housing 3 by exerting on the rod 4 a force perpendicular to the plane of the passage 5. In this position of use, the end portion 17 of the tongue 14 is in abutment on the bottom wall 23 of the cavity 21, and the notch 18 is below

mortise 24.

  This position of use is obtained thanks to a stop plate 30 formed on the cover 22 and which comes to press on the underside 31 of the

  end tabs 19, 20 of the tongue 14.

  As shown in Figures 2 and 3, the cover 22 has, on the one hand, a lower portion 32 which includes the stop plate 30 and which is capable of accommodating in the cavity 21, maintaining the part of end 17 of the tongue 14 resting on the bottom wall 23 of the cavity 21, and, on the other hand, a tenon 33 directed upwards and capable of accommodating in the mortise 24. The tenon 33 is capable of sliding in the notch 18 and it has clipping means 34 which can cooperate with the tabs

2749889

  end 19, 20 of the tongue 14, to prevent the withdrawal of the cover 22, when the latter is partially mounted on the body 6, as is

shown in figure 4.

  In this pre-assembled state, the assembly constituted by the support hook 1 and the sun visor can be presented in the openings made in the headliner 9 and the sheet 2. The snap-on lugs 10 and 11 have on their faces external of the recesses 41 for their snap-fastening on the sheet 2. The width of the space 25 between the two snap-on lugs 10 and 11 is less than the diameter of the mortise 24 and the tenon 33. It is therefore understandable that when the lugs d 'snap have crossed the opening of the sheet 2, these tabs 10 and 11 can be further apart by completely pushing the cover 22 into the cavity 21 from the positions shown in Figures 4 and 5, which ensures the final fixing of the hook

supports 1 on the roof.

  The dimensions of the cover 22 are obviously adapted to the dimensions of the cavity 21 and the mortise 24, to ensure a pre-assembly

  and assembly without special tools.

  To remove hook 1 from the roof, first remove the cover

  22, in order to release the latching tabs 10 and 11.

  The disassembly of the cover 22 is facilitated by a clearance provided between the cover 22 and the hook body 6 and in which the tip can be inserted

  a screwdriver to pry on the cover.
