Description

Armrest for a seat of a mobile motor vehicle pivoting, motor vehicle seat and associated motor vehicle

The present invention generally relates to an armrest for a seat of a motor vehicle.

It relates more particularly to an armrest, which comprises:

a box provided with means for pivotally mounting on said seat, allowing said box to pivot about a pivot axis, and

- A movable element separate from said box, pivotally mounted on said box.

It also relates to a motor vehicle seat comprising such an armrest.

It also relates to a motor vehicle comprising such a seat.

BACKGROUND

To improve the comfort of the passengers or the driver of a motor vehicle, it uses including armrests as defined in the introduction.

These armrests can be deployed to perform their armrest function, or pivoted about said pivot axis of the box to be housed in a recess of the seat. The armrest is then in a retracted position in which it frees up space in the passenger compartment of the motor vehicle.

Moreover, to increase the storage space available in the passenger compartment of this motor vehicle, it is known to provide, inside the box of this armrest, a housing, open on a front face of this box, and can be closed by a pivotally movable cover on the box relative to the motor vehicle seat, around another pivot axis, separate from that of the box.

Such an armrest has the disadvantage of being expensive and complex because it comprises a large number of parts, in particular to allow the pivoting of the box on the seat and the lid on the box, around two separate pivot axes. OBJECT OF THE INVENTION

In order to overcome the aforementioned drawbacks of the state of the art, the present invention provides an armrest comprising a small number of parts, easy to implement and economical.

More particularly, it is proposed according to the invention an armrest as defined in the introduction wherein said movable member comprises as a pivot axis the pivot axis of said box.

The armrest according to the invention thus has a simplified structure. The number of parts is reduced, which facilitates the assembly of the armrest. Its use is also simplified since it is possible to fold the armrest into the recess of the seat back and close the housing provided in this armrest with a single gesture.

Other nonlimiting and advantageous features of the armrest according to the invention are the following:

- said box internally delimiting a housing opening on a front wall of said box, said movable member is adapted to at least partially close said housing of said box;

- The seat having in its folder an opening disposed near said armrest, said movable member is adapted to close said opening;

- There is provided means for limiting the amplitude of the pivoting of said box about said common pivot axis, allowing the pivoting of said box between two first extreme angular positions;

- There are provided blocking means of said box in at least one of said two first extreme angular positions;

said movable element comprises means for limiting the amplitude of pivoting of said movable element about said common pivot axis, allowing said movable element to pivot between two second extreme angular positions; and

- There is provided locking means of said movable member in at least one of said two second extreme angular positions.

Thus, the movable element of the armrest according to the invention has a dual function, it is adapted to close at least partially the housing of said box and / or close the opening of the folder according to its position. The manipulation of such an armrest is then simple and easy.

The invention also relates to a seat of a motor vehicle, comprising a backrest with a rigid frame on which is fixed an armrest as described above.

The invention further relates to a motor vehicle which comprises a seat as described above.

In Figures 1 and 2, there is shown a seat 1 according to the invention intended to be mounted in the passenger compartment of a motor vehicle (not shown).

This seat 1 here comprises a rigid frame 1 1 covered at least in part by a textile coating 12 to form a seat (not shown) and a backrest 14 of the seat 1 (see Figures 1 and 2).

The seat extends substantially parallel to the floor of the motor vehicle, while the backrest 14 extends substantially perpendicular to the floor.

This is a seat 1 forming the rear seat of the motor vehicle. However, the armrest according to the invention can also be envisaged between the front seats of this motor vehicle.

The seat 1 comprises an armrest 3 according to the invention. This armrest 3 is here mounted on the backrest 14 of the seat 1.

This armrest 3 extends here from the backrest 14 of the seat 1, substantially in the middle of the folder 14 taken in its width, so as to separate the seat 1 into two parts each defining a location for a passenger.

The backrest 14 of the seat 1 further comprises here a through opening 15 arranged in a recess 16 of the back 14 of the seat 1 (see Figures 1 and 2), so as to give access to a rear part of the motor vehicle, located at the rear of the seat 1, for example to give access to the trunk of the motor vehicle.

The recess 16 is here formed in the textile covering 12 of the backrest 14 of the seat 1. This recess 16 opens on one side on the outer face of the textile lining 12 of the backrest 14 of the seat 1, towards the front of the motor vehicle, and is partially closed, at the rear, by the frame 1 1 of the backrest 14 of the seat 1. The through opening 15 passes through the frame 1 1 of the seat 1 in the bottom of the recess 16.

Alternatively, one could consider a seat whose backrest would include a recess devoid of through opening.

The recess 16 and the through opening 15 of the backrest 14 of the seat

1 extend near the armrest 3, so that a portion of the armrest 3 is adapted to close at least partially the through opening 15 of the backrest 14 of the seat 1, and so that the recess 16 can accommodate the armrest 3, as explained in more detail later.

For this purpose, the armrest 3 is pivotally mounted on the backrest 14 of the seat 1, between an extended position, in which it plays its role of armrest and extends substantially parallel to the seat of the seat 1, and a folded position in which the armrest 3 is housed in the recess 16 of the backrest 14 of the seat 1.

This armrest 3 here comprises a casing 4 and a movable element 7 separate from the casing 4.

The casing 4 comprises a generally parallelepiped body 21, of elongated shape along a longitudinal axis, with a bottom 27 and a side wall 25 surrounding the bottom 27 (see Figures 1, 2 and 6).

In a general manner, the armrest 3, thus the casing 4 and the mobile element 7, here has a plane of symmetry P1 (see FIG. 1) passing through the longitudinal axis of the casing 4.

The body 21 of the box 4 here comprises a front wall 24 opposite the bottom 27 which comprises a front opening 241 (see Figure 2). This front wall 24 of the body 21 of the box 4 is oriented towards the ceiling (not shown) of the motor vehicle when the armrest 3 is in its deployed position (see figures

1 and 2).

The body 21 of the box 4 internally defines a housing 22 opening on the front opening 241 of the front wall 24 of the body 21 of the box 4 (see Figure 2).

The housing 22 here forms a storage space, for example, a bottle 23 (see Figure 2).

The casing 4 further comprises a rigid frame 5 comprising two arms 51 (see FIGS. 3 to 6) and two spacers 52, 53 interconnecting the ends free of the arms 51 of the frame 5 of the box 4.

These two arms 51 are generally in the form of two parallel L-shaped plates, which extend along the two longitudinal sides of the side wall 25 of the box 4 and are at least partially covered by this box 4.

The body 21 of the box 4 is fixed on the frame 5, for example by an overmolding operation of the body 21 on the frame 5.

The arms 51 of the frame 5 of the box 4 are here made of a rigid material. They are for example made from a metal strip, but one could also consider making them plastic.

The box 4 further comprises pivot mounting means 50, 90 on the seat 1, allowing the pivoting of the box 4 about a pivot axis X1 (see Figures 3 to 6).

These pivotally mounting means 50, 90 of the box 4 on the seat 1 here comprise two lateral supports 90 arranged on either side of the arms 51 of the frame 5 of the box 4 and intended to be fixed on the seat 1, each comprising a pivot mounting member 97 adapted to cooperate with a corresponding pivotal mounting complementary element 50 of the frame 5 of the casing 4.

These additional elements of pivot mounting 50 also belong to the pivot mounting means 50, 90 of the casing 4.

The lateral supports 90 of the box 4 are intended to be fixed on the frame 1 1 of the backrest 14 of the seat 1 (see FIGS. 2 to 5).

Each lateral support 90 of the pivot mounting means 50, 90 of the box 4 here has a general shape at right angles.

More specifically, each lateral support 90 comprises a bearing wall 91 whose one bearing face is intended to be arranged against the armature January 1 of the seat 1 and a mounting wall 96 which extends perpendicularly to the wall of support 91 and which has a mounting face 96A facing the box 4 of the armrest 3 (see Figures 6 and 9 to 1 1).

The bearing wall 91 of each lateral support 90 here comprises two receiving orifices 92 each adapted to receive a fixing element (see FIGS. 3 to 6), for example a fixing screw, for fixing each lateral support 90 on the frame 1 1 of the backrest 14 of the seat 1.

The mounting wall 96 of the lateral support 90 extends parallel to the corresponding arm 51 of the frame 5 of the box 4, close to it.

Each pivot mounting member 97 of the side supports 90 is here in the form of a first pin 97.

Each first pin 97 here has a cylindrical shape and extends from the mounting face 96A of the mounting wall 96, perpendicular to it, towards the box 4 of the armrest 3.

The first two pins 97 of the lateral supports 90 extend opposite one another, along a common longitudinal axis which constitutes the pivot axis X 1 of the casing 4.

These lateral supports 90 are here made of metal.

The complementary elements of pivoting mounting 50 of the frame 5 of the box 4 here comprise two first circular orifices 56, formed in the two free ends facing the arms 51 of the frame 5 intended to be oriented towards the back 14 of the seat 1 in the position deployed from the armrest 3.

These first circular orifices 56 accommodate the first pins 97 of the lateral supports 90 (see FIGS. 9, 10 and 11).

The cooperation of the first pins 97 and the first circular orifices 56 allows the pivoting of the box 4 around the pivot axis X1 of the box 4 relative to the seat 1 of the motor vehicle.

The caisson 4 also comprises means for limiting the amplitude of the pivoting of this caisson 4 around the pivot axis X1, limiting the pivoting of the caisson 4 between two first extreme angular positions, represented in FIGS. 9 and 10 of FIG. a part and in Figure 1 1 on the other hand.

The means for limiting the amplitude of the pivoting of the box 4 comprise limiting elements 98 arranged on the lateral supports 90, which are here in the form of a second pin 98 and complementary limiting elements 57 arranged on the frame 5. of the box 4, here in the form of a first slot 57.

Each second pin 98 of the lateral supports 90 has here a cylindrical shape and extends from the mounting face 96A of the mounting wall 96 of the lateral support 90 corresponding, perpendicular to it, towards the caisson 4.

This second pin 98 is quite similar to the first pin 97 of the lateral support 90 and is therefore parallel to it, close to it.

The two second pins 98 of the lateral supports 90 extend opposite one another, along a common longitudinal axis parallel to the pivot axis X 1 of the casing 4.

The first slot 57 of each arm 51 of the frame 5 of the box 4 has the shape of an arc whose center (see FIGS. 6 and 8) coincides with the center of the first circular orifice 56 adjacent to the arm 51, which houses the first pin 97 of the lateral support 90 corresponding.

Each first slot 57 of the arm of the frame 5 here extends over an angular range of about 1 15 degrees. When the arm 51 of the frame 5 of the box 4 pivots around the first pin 97 corresponding, the second pin 98 corresponding navigates in the first slot 57 corresponding.

The angular extent of each first slot 57 of the arms 51 of the frame 5 of the box 4 defines the maximum pivoting amplitude of the box 4.

Indeed, each end of the first slot 57 of the arm 51 of the frame 5 of the box 4 forms a stop adapted to stop the second pin 98 of the corresponding lateral support 90 to limit the amplitude of its stroke in the first slot 57.

Each first extreme angular position of the box 4, relative to the seat 1, is thus reached during the abutment of the second pins 98 of the lateral supports 90 on one end of the first slots 57 of the arms 51 of the frame 5 of the box 4.

These first two extreme angular positions are here separated by an angle of about 1 15 degrees.

Alternatively, one could consider a first slot 57 extending at an angle between 60 degrees and 120 degrees.

More particularly, the first two extreme angular positions of the box 4 correspond to the deployed and folded positions of the armrest 3 described above.

In the extended position of the casing 4 (see FIGS. 1, 2, 9 and 10), the front and rear walls 27 and the casing 4 (see FIGS. 1, 2 and 6) extend substantially parallel to the ceiling and the floor. of the motor vehicle. In the folded position against the seat 1 of the box 4 (see Figures 5 and 1 1), the box 4 is housed in the recess 16 of the backrest 14 of the seat 1, so that the front wall 24 of the box 4 extends against the bottom of the recess 16, constituted here by the frame 1 1 of the seat 1, and the rear wall 27 of the box 4 extends in the extension of the outer face of the textile coating 12 of the seat 1.

In addition, the casing 4 comprises locking means in at least one of these first extreme angular positions.

These locking means here comprise two intermediate parts 100 adapted to cooperate with the second pins 98 of the lateral supports 90 to block the box 4 in one of the first extreme angular positions.

Each intermediate piece 100 generally has the shape of an angular sector of a disk and comprises:

on the one hand, a second circular orifice 106 passing through, similar to the first circular orifice 56 of the arm 51 of the frame 5 of the box 4, and

- Secondly, a second slot 107 similar to the first slot 57 of the arm 51 of the frame 5 of the box 4, having the shape of an arc whose center coincides with the center of the second circular hole 106 adjacent to the intermediate part 100, and which extends over an angular range identical to that of the first slot 57 of the arm 51, that is to say between 60 and 120 degrees and corresponding here to 1 15 degrees.

Each intermediate piece 100 is attached to an outer face 51 B of the corresponding arm 51 of the frame 5 (see FIG. 6), oriented towards the mounting face 96A of the mounting wall 96 of the corresponding lateral support 90, so as to be positioned between the arm 51 of the frame 5 of the box 4 (see Figures 6, 9 and 10) and the mounting wall 96 of the corresponding lateral support 90.

For this purpose, each intermediate piece 100 comprises latching means 101, 102 (see FIGS. 9 and 10) which cooperate with complementary latching means 571, 56 (see FIG. 8) arranged on the corresponding arm 51 of the frame 5. of the box 4.

The latching means 101, 102 of each intermediate piece 100 comprise here:

a plurality of latching lugs 102 forming a snap-fitting sleeve snapped into the first circular orifice 56 of the arm 51 corresponding frame 5 of box 4, and

two attachment tabs 101 (FIGS. 9 to 11) each hooked into a notch 571 of the first slot 57 of the corresponding arm 51 of the frame 5 of the casing 4.

Each latching lug 102 rises from the face of the intermediate piece 100 oriented towards the corresponding arm 51 of the frame 5 of the box 4, perpendicular thereto, and along the edge of the second circular orifice 106. comprises at its free end a catching tooth which is hooked on an inner face 51A of the arm 51 of the frame 5 of the box 4, opposite to the outer face 51B.

The detent sleeve formed by the latching tabs 102 accommodates the first pin 97 of the corresponding lateral support 90. For this purpose, the internal diameter of this sleeve is substantially equal to the diameter of said first pin 97.

Each attachment lug 101 rises from said face of the intermediate piece 100 facing the arm 51 of the frame 5, perpendicular thereto, near one end of the second slot 107. Each leg fastening 101 comprises at its free end a catching tooth which is hooked on the inner face 51A of the arm 51 of the frame 5 of the box 4, at said notch 571 of the first slot 57 of the arm 51 corresponding to the frame 5 of the box 4.

The intermediate piece 100 is secured to the arm 51 of the frame 5 of the box 4 on which it is attached and does not pivot relative thereto.

The second slot 107 of each intermediate piece 100 extends facing the first slot 57 of the corresponding arm 51 of the frame 5 of the box 4, along the latter, and the ends of this second slot 107 are arranged opposite the ends of this first slot 57. The ends of this second slot 107 thus also form a stop adapted to stop the second pin 98 of the corresponding lateral support 90 to limit the amplitude of its stroke in said first and second slots 57, 107.

Unlike the first slots 57 of the arms 51 of the frame 5 of the box 4, one of the parallel arcuate edges of each second slot 107 of the intermediate pieces 100 has a boss 108 (see Figure 10) projecting from the interior of this second slot 107 and forming a point passage hard adapted to cooperate with the second pin 98 of the lateral support 90 corresponding to block the pivoting of the box 4.

More precisely, this hump 108 is positioned near one of the ends of the second slot 107, so that when the second pin 98 passes the hard point passage defined by this hump 108, it comes into abutment against the corresponding end of the second slot 107 and is then blocked between this end and the boss 108.

The arms 51 of the frame 5 of the box 4 and the first and second pins 97, 98 of the lateral supports 90 are here made of metal, the intermediate parts 100 are made of plastic. The presence of this intermediate piece 100 disposed between the arms 51 and the first and second pins 97, 98 of the lateral supports 90 makes it possible to limit the metal-metal contacts during the pivoting of the box 4, so as to reduce the noises related to this pivoting. .

In the example shown here, as explained in more detail later, the blocking means of the box 4 block it in its folded position in the folder 14 of the seat 1.

Alternatively, it can be envisaged that the locking means block the box in its deployed position or in its two first extreme angular positions folded and deployed. It suffices to provide a bump at the other end of the second slots of the intermediate piece or at both ends of these second slots.

According to an alternative embodiment not shown, one could consider an armrest devoid of intermediate parts. The locking means can then be provided directly on the arms of the box frame by adding a similar bump to that of said second slots of the intermediate pieces in the edge of each first slot of these arms. The casing 4 finally comprises a seal 26 (FIGS. 4, 6 and 8) which surrounds the front opening 241 of the front wall 24 of the body 21 of the casing 4.

This seal 26 is made of flexible material and accommodates the movable member 7 when the latter closes the front opening 241 giving access to the housing 22 of the body 21 of the box 4, as explained below.

The closure of the housing 22 can thus advantageously be sealed.

The movable element 7 of the armrest 3 here comprises a plate 71 rectangular and pivot mounting means 70 on the casing 4 (see Figures 6, 7, 10 and 1 1).

The plate 71 of the movable element 7 has dimensions adapted to the closure of the front opening 241 of the front wall 24 of the box 4. It can be made of different materials, according to the desired aesthetic appearance for the moving element. 7. It is for example made of wood, bamboo or plastic.

The pivotally mounted mounting means 70 of the movable member 7 on the casing 4 here comprise a support 80 (see FIGS. 2 to 7).

This support 80 extends here from a rear face 71A of the plate 71, oriented towards the box 4 when the movable element 7 closes the front opening 241 of the body 21 of the box 4 giving access to the housing 22 ( see Figure 6).

The support 80 is made here of plastic, but it could be provided that it is made of a metallic material.

This support 80 here comprises four walls 81, 82, 83.

It comprises a flat fixing wall 81 fixed to the plate 71 of the movable element 7 (see FIGS. 6, 7 and 9 to 1 1). This fixing wall 81 here comprises for this purpose two fixing screw receiving holes. The two fastening screws also pass through two housing orifices of a portion of the fastening screw provided on the plate 71.

The support 80 also comprises two side walls 82 of generally trapezoidal shape which extend vis-a-vis from the fixing wall 81, perpendicular to it. Each side wall 82 of the support 80 comprises a cutout 82A allowing pivoting of the support 80 around the first and second pins 97, 98 of the lateral support 90 corresponding, as explained below. This cut 82A saves a portion of the side wall 82 forming a mounting tab of the support 80.

The support 80 finally comprises a protective wall 83 which extends, between the two lateral walls 82 of the support 80, along the fixing wall 81.

As shown in Figures 9 to 1 1, the protective wall 83 is here adapted to prohibit any free passage between the armrest 3 and the backrest 14 of the seat 1, particularly when the movable member 7 closes the opening 15 of the backrest 14 of the seat (see Figure 10).

As shown in FIG. 7, the support 80 extends between two sides longitudinals of the plate 71, along one of the transverse sides 72 of the plate 71 (see Figure 6).

More specifically, the support 80 of the movable element 7 extends along the transverse side 72 of the plate 71, the closest to the lateral supports 90 of the casing 4.

The support 80 comprises two circular openings 86, each formed near the free edge of the mounting lug of each side wall 82 of the support 80.

The circular openings 86 are open facing each other, so that they are aligned along an axis X 2 (see FIGS. 6 and 7) parallel to the plate 71 of the mobile element 7. These circular openings 86 of the support 80 of the plate 71 of the movable element 7 here host the first pins 97 of the lateral supports 90 and cooperate with them so as to allow the pivoting of the mobile element 7 around these first pins 97.

Each first pin 97 of the lateral supports 90 thus crosses the corresponding circular opening 86 of the support 80 of the mobile element 7 and the circular opening 56 of the corresponding arm 51 of the frame 5 of the caisson 4. It also passes through the sleeve of the snap of the corresponding intermediate part 100.

Thus, remarkably, the movable element 7 is pivotally mounted on the caisson 4 about the pivot axis X1 of this caisson 4, defined here by the axis of the first pins 97 of the lateral supports 90 (see FIGS. 1 1).

The circular openings 86 of the support 80 of the movable element 7 here have a diameter equal, with the clearance, to the diameter of the first pins 97 of the lateral supports 90.

The movable element 7 of the armrest 3 further comprises means for limiting the amplitude of the pivoting around the common pivot axis X1, limiting the pivoting of the movable element 7 relative to the casing 4 between two second extreme angular positions, shown in Figure 9 on the one hand and in Figures 10 and 1 1 on the other hand. These two second extreme angular positions of the movable element 7 are here separated by an angle of about 1 15 degrees.

The means for limiting the amplitude of pivoting of the element mobile 7 comprise here, on the one hand, the box 4 itself, and on the other hand, two notches 87 flared each formed in the mounting lug of one of the side walls 82 of the support 80 of the movable member 7 (Figure 7).

Indeed, the box 4 of the armrest 3 limits the amplitude of the pivoting of the movable element 7 in the direction of this box 4: one of the two second extreme angular positions of the movable element 7 here constitutes a position of closing the front opening 241 of the body 21 of the box 4 giving access to the housing 22 when the latter is in its extended extended position (see Figures 1 to 3 and 9).

In this position, the mobile element 7 is in abutment against the casing 4 of the armrest 3.

The other of the two second extreme angular positions of the movable element 7 constitutes a position of maximum opening of the front opening 241 of the body 21 of the box 4 when the latter is in its extended extended position (see FIGS. 10). Here, advantageously, the maximum open position of the movable element 7 corresponds to a closed position of the through opening 15 of the backrest 14 of the seat 1 (see FIGS. 4 and 11), in which the movable element 7 closes the through opening 15 of the seat 1.

The mobile element 7 thus advantageously fulfills a dual function, it plays the role, on the one hand, of a lid adapted to close the front opening 241 of the body 21 of the box 4 giving access to the housing 22 (see FIG. 6) and, secondly, a flap adapted to close the through opening 15 arranged in the recess 16 of the back 14 of the seat 1 (see Figure 4).

The notches 87 thus cooperate with the second pins 98 of the lateral supports 90 to stop the pivoting of the mobile element 7, in the maximum open position of the front opening 241 of the body 21 of the box 4.

Indeed, each second pin 98 of the side support 90 abuts against the bottom of the notch 87 when the movable member 7 reaches said maximum open position of the front opening 241 of the body 21 of the box 4.

Each notch 87 here has a width equal, with play, to the diameter of the second pin 98 of the corresponding lateral support 90.

The movable element 7 also comprises locking means of the movable element 7 in this position of maximum opening of the front opening 241 of the body 21 of the box 4. These locking means here comprise a boss 88 (see FIGS. 7 and 9) provided in the edge of the notch 87 and projecting inside this notch 87, so as to form a hard point passage (see FIGS. and 9) adapted to cooperate with the second pin 98 of the corresponding lateral support 90 to block the pivoting of the mobile element 7.

Indeed, the hump 88 is positioned in the edge of each notch 87, near the bottom thereof, so that when the second pin 98 of the lateral support 90 of the box 4 passes the hard point passage defined by this hump 88, it comes into abutment against the bottom of the notch and is then locked between this bottom and the boss 88 of the notch 87 of the support 80 of the movable element 7.

The movable element 7 finally comprises a strap 73 (see FIGS. 2, 4 to 6) fixed to the plate 71 of the movable element 7, on the rear face 71 A of the plate 71, oriented towards the casing 4 when the movable member 7 closes the front opening 241 of the body 21 of the box 4 (see Figure 6), to facilitate the handling of the movable member 7 by a user.

In practice, as previously explained, the casing 4 is pivotally movable about the common pivot axis X1, between the extended position of the casing 4 (see FIGS. 1, 2, 9 and 10) and the retracted position of the casing 4 (FIGS. Figure 1 1).

The movable member 7 is pivotally movable about the common pivot axis X1, between the closed position of the front opening 241 of the body 21 of the box 4 and the maximum open position of this opening 241 before the body 21 of the box 4, wherein the through opening 15 of the backrest 14 of the seat 1 is closed by this movable element 7.

There are therefore three preferred configurations for the armrest 3:

a first configuration (FIGS. 3 and 9) in which the casing 4 is deployed and the movable element 7 closes the front opening 241 of the body 21 of the casing 4,

a second configuration (FIGS. 4 and 10) in which the casing 4 is deployed and the movable element 7 leaves open the front opening 241 of the body 21 of the casing 4 and closes the through opening 15 of the backrest 14 of the seat 1, and

a third configuration (FIGS. 5 and 11) in which the box 4 is folded back into the recess 16 of the backrest 14 and the mobile element 7 automatically closes the front opening 241 of the body 21 of the box 4 and the opening through 15 of the folder 14 of the seat 1.

In order to allow a clear representation of the pivot mounting elements of the box 4 and the movable member 7, parts of the armrest are omitted from FIGS. 3 to 5 and 9 to 1 1: the body 21 of the box 4 is omitted Figures 3 to 5, 8 and 9 to 1 1, one of the two side supports 90 is omitted from Figures 9 to 1 1; the arm of the box frame corresponding to this lateral support is omitted from FIGS. 10 and 11 and the plate of the movable element is omitted from FIG.

Although one of the lateral supports is omitted from FIGS. 10 and 11, the first and second pins 97, 98 of this lateral support omitted are represented in these FIGS. 10 and 11.

In said first configuration of the armrest 3, shown in Figures 3 and 9, the second pin 98 of each lateral support 90 of the box 4 of the armrest 3 abuts against a first end of the first slot 57 of the arm 51 corresponding frame 5 of the box 4, and therefore also against the corresponding first end of the second slot 107 of the corresponding intermediate part 100. The movable element 7 is in abutment against the caisson 4.

When the user wishes to access the contents of the housing 22 of the box 4 of the armrest 3, he rotates the movable member 7 to put it in its maximum open position of the front opening 241 of the body 21 of the box 4. The armrest 3 then passes in its second configuration, shown in Figures 4 and 10.

For this purpose, the user rotates the movable member 7 around the first pins 97 of the lateral supports 90 of the box 4, until each notch 87 of the support 80 of the movable member 7 comes to engage on the corresponding second pin 98 of the lateral support 90 and that it passes the hard point passage provided in this notch 87 of the movable member 7 so as to lock the movable member 7 in its maximum open position of the opening before 241 of the body 21 of the caisson 4.

In this position of maximum opening of the front opening 241 of the body 21 of the box 4, the second pins 98 of the lateral supports 90 are each housed between the corresponding boss 88 of the edge of the notch 87 and the bottom of the notch Corresponding 87 of the support 80 of the movable element 7.

The housing 22 of the box 4 is then open at the front of the box 4 and the user can access this housing 22 through the front opening 241 of the front wall 24 of the body 21 of the box 4, for example to deposit or take the bottle 23.

In addition, in this position of maximum opening of the front opening 241 of the body 21 of the box 4, the movable member 7 closes the through opening 15 of the bottom of the recess 16 of the back 14 of the seat 1.

In order to close the front opening 241 of the body 21 of the box 4 giving access to the housing 22, the user rotates the movable member 7 in the other direction. The second pin 98 leaves the notch 87 of the support 80 of the movable member 7 and the plate 71 of the movable member 7 is pressed against the seal 26 surrounding the front opening 241 of the front wall 24 of the body 21 of the box 4 (Figure 9).

The through opening 15 of the backrest 14 of the seat 1 is then opened again.

To move the armrest 3 from its first configuration, shown in Figures 3 and 9, to its third configuration, shown in Figures 5 and 1 1, the user simultaneously rotates the box 4 and the movable member 7, around the first pins 97 of the lateral supports 90. In doing so, the second pin 98 of each lateral support 90 navigates in the first slot 57 of the corresponding arm 51 of the frame 5 of the box 4 and in the second slot 107 of the intermediate piece 100, from said first end of these first and second slots 57, 107, until each second pin 98 of the side supports 90 abuts against the second end of the first slot 57 of the corresponding arm 51 of the frame 5 of the box 4 and against the second end of the second slot 107 of the corresponding intermediate part 100.

At the end of the stroke, the second pin 98 passes the hard point passage defined by the boss 108 projecting into the second slot 107 of the corresponding intermediate piece 100. The second pins 98 of the lateral supports 90 are then each housed between the boss 108 of the corresponding intermediate piece 100 and said second end of the second slot 107 of the corresponding intermediate piece 100.

Simultaneously, the second pins 98 of the side supports 90 slide in the notch 87 of the support 80 of the movable member 7 and are housed between the boss 88 of the edge of the notch 87 and the bottom of the notch 87 corresponding support 80.

The armrest 3 is then locked in its third configuration.

The user can also move the armrest 3 directly from its second configuration to the third configuration. In doing so, the second pin 98 of each lateral support 90 of the casing 4 of the armrest 3 navigates in the first and second slots 57, 107 provided in the corresponding arms 51 of the frame 5 of the casing 4 and in the corresponding intermediate pieces 100 of the casing 4. the manner described with reference to the transition from the first to the third configuration.

The user can thus free space on the seat 1 of the motor vehicle.

The present invention is not limited to the embodiment described and shown, but the skilled person will be able to make any variant within his mind.

According to an alternative embodiment not shown, it could be envisaged that the lateral supports comprising the first and second pins form a single piece attached to the frame of the seat.
