Abstract

The modular seat arrangement for vehicles comprises pivoting systems for one or both of the rear seats. This allows a seat to be rotated so that it rests on the side of the seat cushion (8) and back (7) and moved back into the boot so that the top of the back rests against the side of the seat (6) in front.

Description

2890611 1

  The invention relates to a device for modular arrangement of seats in a motor vehicle.

  More particularly, the invention finds application in the interior spaces of small urban vehicles without trunk or whose trunk volume is very small.

  The modularity of current vehicles and, in particular that of the seats, is constantly improved and makes it possible to increase the load capacity of the boot by folding all or part of these seats.

  According to the state of the art, a rear seat arrangement device, which allows unfolding the seat elements, including the seat and backrest, to release a storage space to increase the volume of the trunk.

  Referring to Figures 1 and 2 which show such a device of the prior art, said vehicle is provided with a trunk 1 which is formed in a boot floor 2, covered by a trunk shelf 3 and laterally delimited by two sides checkout 4.

  In addition, the vehicle is provided with two adjacent rear seats 5, 6, each of said seats 5, 6 being provided with a backrest 7 and a seat 8 corresponding.

  When at least one of these rear seats 5, 6 is flexible, that is to say that its backrest 7 and seat 8 are movable, we can unfold the seat concerned to increase the volume of the trunk 1 and increase the load capacity of the vehicle.

  For this, the movable seat 8 is pivotally mounted about a transverse pivot axis Y1 substantially perpendicular to the longitudinal axis XX 'of the vehicle and disposed at the lower edge 831 of the front edge 83 of the seat 8, the pivoting of the seat 8 taking place along the arrow F2 shown in FIG.

  The backrest 7 is also pivotally mounted, according to the prior art, around a transverse pivot axis Y11 substantially perpendicular to the axis XX 'and disposed at the lower edge 751 of the front face 75 of the backrest. 7, and the unfolding of the backrest 7 is effected according to the arrow F1 shown in FIG.

  The modularity, according to this example of the prior art shown in particular in Figure 2, is obtained, in a first step, by rotating the seat 8 of the seat 5 around the axis Yl from its initial position of use A to an open end position B in which the seat 8 can be pressed against the back of the corresponding front seat, not shown.

  Then, in a second step, the backrest 7 pivots around the axis Y11 from its initial use position C to an unfolded final position D in which the backrest 7 bears against the surface 132 disengaged by the pivoting of the seat 8 described above.

  Once the seat 8 thus raised and the corresponding backrest 7 unfolded, an additional storage space 13 is made available to increase the load capacity of the trunk 1 to store more objects 40 in the passenger compartment of the vehicle these objects 40 can be placed on the unfolded folder 7.

  This device finds its application in the same way in the case of a five-seater vehicle provided with three adjustable rear seats not shown, but also in the case of modular seats such as, for example, 1/3 - 2/3 .

  Depending on the case, it is possible to selectively unfold one or two seats, or even all the seats according to the method described above in order to increase the volume of the trunk 1.

  However, the modular arrangement devices described above have the following drawbacks.

  2890611 3 The storage space 13 is slightly raised relative to the boot floor 2 a height proportional to the thickness of the backrest 7, which results in the relative length objects arranged from the trunk 1 to this storage space 13 are in an unstable position.

  Furthermore, the occupants of the vehicle, and more particularly those occupying the adjacent seat 6, may be confronted with security problems during an impact or other maneuver due to the presence of objects 40 placed on the backrest 7 in the seat. the storage space 13 to the side of this adjacent seat 6.

  Finally, the objects 40 disposed in this storage space 13 are visible from outside the vehicle and can encourage theft. In this context, the invention relates to a seat arrangement device allowing in particular to overcome the aforementioned drawbacks.

  For this, the device of the invention, moreover, conforming to the generic definition given in the preamble above, is essentially characterized in that the device comprises means for disengaging 10 of at least the first seat element. 8 of at least one of the seats 5, 6 of the vehicle from its initial use position A to an inactive end position B, and said device further comprises displacement means 9 of the second seat member 7 from its position initial use C to an inactive end position D so that said second member 7 thus moved forms a partition between the adjacent seat 6 in the normal position of use and the storage space 13 made available by the release of the first element 8 and the displacement of the second element 7.

  Preferably, the means of clearance 10 of the seat 8 comprise a transverse pivot axis Y1 which is substantially perpendicular to the longitudinal axis XX 'of the vehicle, is arranged at the front edge 83 of the seat 8 and around which the seat 8 is rotatably mounted.

  Advantageously, the displacement means 9 of the backrest 7 comprise a vertical pivot axis Z1 perpendicular to the longitudinal axis XX 'of the vehicle, which is disposed at the inner lateral edge 72 of the backrest 7 and around which the backrest 7 is mounted movably in rotation so that the backrest 7 can be moved to and to its final position E when the seat 8 is in its final inactive position B. In addition, the device may comprise a storage space covering element mobile 11 which is movable between an initial inactive position F and an active unfolded position I and thus covering the entire storage space 13 in the continuity of the shelf 3 of the trunk 1 located behind the adjacent seats 5, 6.

  For example, in its initial inactive position F, the movable covering element 11 is secured to the lower face 86 of the seat 8 in its initial use position A or said element 11 is integral with the inner face 41 on the side 4 of the vehicle.

  Preferably, the cover member 11 is made of a relatively rigid material and is pivotally mounted relative to the open seat 8 about a transverse pivot axis Y2 which is substantially perpendicular to the longitudinal axis XX 'of the vehicle and which is disposed at the upper edge 84 of the seat 8 in its final position B, this upper edge 84 being disposed at a height H substantially equal to the height of the trunk shelf 3, or said element 11 is pivotally mounted around a longitudinal pivot axis X3 disposed at the body side 4 at a height H substantially equal to the height of the trunk shelf 3.

  Preferably, the covering element 11 is a stretchable roll 111 which is either completely integrated in the seat 8 integrally in a transverse recess 112 at the rear face 86 of the seat 8 and opposite to the pivot axis Y1 is integral with the body side 4 being located at a height H substantially equal to the height of the trunk shelf 3.

  Advantageously, the backrest 7 is provided with a mobile shelf 12 movable between an initial inactive position G and a final unfolding position J in which a flat floor 131 is made available in the storage space 13 in the continuity of the floor trunk 2, said shelf 12 is integral with the side face 76 of the folder 7 considered in its final position moved E on the side of the storage space.

  For example, the movable tablet 12 is pivotally mounted about a longitudinal axis of pivot Xl which is disposed at the lower edge 761 of the outer side face 76 of the folder 7 considered in its final displaced position E, said tablet 12 extends approximately over the entire surface of this outer side face 76 and this shelf 12 is made of a relatively rigid material for supporting the load of objects arranged in the storage space 13.

  Preferably, the backrest 7 comprises a mobile shelf 17 secured to the inner side face of the side of the adjacent seat 75 of the backrest 7 considered in its final position E and which is pivotally mounted about a longitudinal pivot axis X2 and pivots since an inactive initial position K in the extension of the lateral face 75 to an active use position L in which said shelf 17 forms an armrest to the passenger of the adjacent seat 6.

  In addition, the adjacent seats 5, 6 may be the rear seats of the vehicle.

  The references of the constituent elements common to the prior art illustrated in FIGS. 1 and 2 and to the invention are shown in FIGS. 3 to 6.

  Referring to Figure 3, a trunk 1 is formed in the boot floor 2, covered by the trunk shelf 3 and laterally delimited by the body sides 4.

  The two rear adjacent seats 5, 6 are each provided with a backrest 7 and a seat 8 shown in Figure 3 in their respective initial use position C, A. The movable seat 8 is pivotally mounted, since its initial use position A to a final open position B about a transverse pivot axis Y1 substantially perpendicular to the longitudinal axis XX 'and disposed at the lower edge 831 of the front edge 83 of the seat 8, the pivoting of the seat 8 taking place along the arrow F2 shown in FIG.

  In its final open position B, the seat 8 can bear against the back of the corresponding front seat not shown.

  The backrest 7 is pivotally mounted, from its initial use position C to an end position displaced E visible in Figure 4, about a vertical pivot axis Z1 perpendicular to the axis X-X ' , said axis Z1 being disposed at the front edge 721 of the inner lateral edge 72 of the backrest 7.

  The unfolding of the backrest 7 is effected according to the arrow F3 shown in FIG. 3, allowing the backrest 7 to move from its initial use position C to a final position E in which this backrest 7 can bear against the inner side edge. 61 of the adjacent seat back 6.

  2890611 8 As shown in Figure 4, after pivoting of the seat 8 and the backrest 7 as described above, a storage space 13 is formed on the side of the unfolded seat 5 and is arranged in the continuity of the trunk 2.

  The storage space 13 thus obtained has a surface similar to the surface of the seat 8.

  Moreover, the floor of this space 131 is in the continuity of the boot floor 2.

  Locking means not shown can be provided at the backrest 7 and / or the seat 8, for example on the lateral face 76 of the backrest 7 and / or on the rear face 86 of the seat 8, or even at their respective pivot axis Z1 and Y1, thereby blocking the backrest 7 and seat 8 in their respective inactive end position E, B and prevent their fall when moving the vehicle to make the storage space 13 more secure.

  According to FIGS. 4 and 5, the backrest 7 is equipped with a mobile shelf 12 which is integral with the outer lateral face 76 of the backrest 7 and which is pivotally mounted relative to this backrest 7 about a longitudinal pivot axis X 1 arranged at the lower edge 761 of the side face 76.

  The tablet 12 is made of a sufficiently rigid and resistant material for placing relatively heavy objects in the storage space 13 without this tablet 12 is degraded.

  This shelf 12 is made of a material identical to that of the floor of the trunk 2 so that the perception both in the trunk 1 and in the storage space 13 is homogeneous.

  In addition, with reference to Figures 4 and 5, the seat 8 is equipped with a movable covering element 11, to cover in the continuity of the trunk shelf 3 the storage space 13 created.

  To this end, the movable covering element 11 is secured to the rear face of the seat 86 and is pivotally mounted, from its initial position F to a final position I covering the storage space 13, around a transverse pivot axis Y2 disposed at the upper edge 861 of the rear face 86 of the seat 8.

  In another embodiment, the covering element 11 can be secured to the body side 4 shown in FIG. 5 by being pivotally mounted about a longitudinal pivot axis X3 which is disposed at a height H substantially equal to chest height 1.

  The covering element 11 is made of a relatively rigid material identical to that of the trunk shelf 3 thus improving the perceived quality of the outside of the entire trunk 1.

  When the covering element 11 is secured to the seat 8, it extends over the entire surface of the rear face of the seat 86 and when the covering element 11 is secured to the body side 4, it presents an area approximately equal to the floor area 131 of the storage space 13.

  The covering element 11 has the advantage of not bringing to the sight of malicious persons objects disposed in the trunk 1 and more particularly in the storage space 13.

  The device also comprises not shown locking means of the covering means 11 in its final position I that the skilled person can determine.

  Instead of a covering means 11 as described above, it can be provided to use a stretchable roll 111 fulfilling the same function and which can be arranged either at the rear face 86 of the seat 8, or at the cash side 4.

  As shown in FIGS. 7 and 8, so as not to hinder the seat 8 in its initial use position A, the stretchable roll 111 is placed under the seat 8 while being completely and integrally housed in a transverse recess. 112 at the rear face 86 of the seat 8 and opposite to the pivot axis Y1.

  When the seat 8 is considered in its final inactive position B, as shown in Figures 9 and 10, the roller 111 is at a horizontal position of a height H substantially equal to the height of the trunk shelf 3.

  FIG. 10 shows that the stretchable roll 111 extends substantially along the upper edge 861 of the rear face 86 of the seat 8 considered in its final inactive position B. The surface which it occupies when stretched corresponds to the surface of the storage space 13.

  In addition, once stretched, the roller 111 can be fixed to the trunk shelf 3 when it is secured to the seat 8 or the backrest 7 at its outer side face 76 when it is secured to the body side 4, not shown, by known fastening means.

  The stretchable roll 111 may be made of a flexible material having an appearance identical to that of the trunkboard 3 so that the perception of the trunk tablet 3 - stretchable roll 111 is homogeneous.

  Referring to Figure 6, a mobile armrest 17 is disposed in a rectangular opening 18 fully fitted inside the backrest 7 at its inner side face 75.

  Said movable tablet 17 is integral with the lateral face 75 of the backrest 7 and is pivotally mounted about a longitudinal pivot axis X2 disposed at the lower edge 19 of the opening 18 thus making it possible to pivot the tablet 17 from its position The initial operation of the device of the invention is described below.

  When occupants of the vehicle want to settle inside the passenger compartment, the adjacent seats 5, 6 are in their initial position of use A, C as represented in FIG.

  However, to transport objects in the trunk 1, provided that at least one of the rear adjacent seats 5, 6 is not occupied, said seat 5 or 6 is unfolded, as described with reference to FIGS. 3 and 4, of to increase the volume of the chest 1 thanks to the storage space 13 thus made available.

  The unfolding of at least one of said seats 5, 6 is effected, initially, by a pivoting of the seat 8 from its initial use position A to a final position B which may, for example , be in support against the back of the front seat.

  The pivoting of the seat 8 around the transverse pivot axis Y1 is effected according to the arrow F2 shown in FIG.

  The seat 8 in its final position B also makes it possible to protect said front seat against possible shocks coming from the rear of the vehicle.

  In a second step, the backrest 7 pivots, from its initial use position C to its final position E, preferably, in abutment against the lateral edge 61 of the adjacent seat 6, around the vertical axis Z1 along the arrow F3 shown in Figure 3.

  The backrest 7 in its final position forms a partition between the adjacent seat 6 and the storage space 13 and thus prevents the passage of objects arranged in this storage space 13 to the adjacent seat 6 in case of shocks.

  After pivoting the seat 8 and the backrest 7, the useful interior volume of the trunk is increased by 2890611 12 this storage space 13 thus created, and the cabin is compartmentalized at the same time.

  To make the floor of the storage space 131 flat, the mobile shelf 12 of the backrest 7 pivots around the axis X1 from its initial use position G to a final position J in which it rests on the floor of the storage space 131.

  The pivoting of the tablet 12 is effected along the arrow F6 shown in FIG.

  To cover said storage space 13, the covering element 11 secured to the seat 8 pivots about the transverse axis Y2, from its initial inactive position F to its final overlap position I. The pivoting of the covering element 11 is carried out according to the arrow F4 shown in FIG.

  When this covering element 11 is integral with the body side 4, it pivots around the axis X3 from its initial position, not represented, to its final overlap position I, the pivoting taking place along the arrow F5 shown in FIG. figure 5.

  When this covering element 11 is a stretchable roll 111 completely integrated in the seat 8, it is stretched and then fixed to the trunkboard 3 and when the roll 111 is secured to the body side 4 it is fixed to the folder 7 considered in its final inactive position D to cover the storage space 13.

  The backrest 7 and the seat 8 in their respective pivoting can be electrically controlled, for example, using an electrical box actuated with a button from the dashboard, not shown.

  A control circuit may be provided in the backrest 7 and / or the seat 8 to receive the signal emanating from the electrical box.

  2890611 13 It is also possible, for example by means of cranks or tabs not shown, to allow to grab the backrest 7 or the seat 8 and rotate about their respective pivot axis Z1, Yl.

  It is possible to obtain kinematics close to that described above in a multitude of ways in accordance with the invention.

  For example, the invention describes an arrangement device for rear seats but it is possible to provide this device for the front passenger seat to clear the space occupied by the front seat and possibly transform the vehicle to four or five places in a single-seater vehicle.

  It is also possible for the backrest 7 to be movable by disengagement, that is to say, that the backrest 7 can be completely disengaged from its initial position of use C by manual gripping and then be positioned and locked in its final inactive position. E. It is also possible that it is the seat 8 which, in its final position forms partition between the adjacent seat 6 and the storage space 13.

  In this case, the backrest 7 can be left in its initial position C to compartmentalize the storage space 13 or can be completely disengaged to extend the boot floor 2.

  All these variations are of course within the scope of the invention.
