Detailed Description
In the following description, when reference is made to absolute positional qualifiers, such as "front", "rear", "upper", "lower", "left", "right", etc., or relative positional qualifiers, such as "upper", "lower", "upper" and "lower", etc., or orientation qualifiers, such as "horizontal", "vertical", etc., unless otherwise specified, shall be consistent with the orientation of the figure or seat in its normal use position.
Hereinafter, the longitudinal direction X refers to the longitudinal direction of the seat assembly. The longitudinal direction of the seat assembly is considered to be the same as the longitudinal direction of the motor vehicle in which the seat assembly is mounted. The longitudinal direction X corresponds to the direction of normal travel of the vehicle. The longitudinal direction X is preferably horizontal. The transverse direction Y is the transverse direction of the seat assembly. The transverse direction of the seat assembly corresponds to a transverse or lateral direction of the motor vehicle. The lateral direction Y corresponds to a direction perpendicular to the normal running direction of the vehicle. The transverse direction Y is preferably horizontal. Finally, the vertical direction Z is the vertical direction of the seat assembly, perpendicular to the longitudinal direction X and the transverse direction Y. The vertical direction Z is preferably oriented upward, and the trihedron X, Y, Z is direct.
Fig. 1 shows the seat assemblies 10, 100 arranged side by side in the transverse direction Y. Thus, the two seat assemblies 10, 100 may form a second row of seats of the motor vehicle.
In the illustrated example, the first seat assembly 10 includes two seats 12a, 12b. The first seat assembly 10 includes a seat base frame 14 common to both seats 12a, 12b and a seat back frame 16a, 16b dedicated to each seat 12a, 12b. Each seat back frame 16a, 16b is rotatably mounted about a common transverse axis A1 relative to the seat base frame 14 by a respective hinge arrangement 18a, 18 b. Such hinge means 18a, 18b are well known to those skilled in the art. Accordingly, the hinge devices 18a, 18b are not described in detail below.
In the example shown, each backrest frame 16a, 16b includes a tubular frame 20a, 20b. Here, sockets 22a, 22b for receiving support rods of a headrest (not shown) are fastened to the upper cross members of the tubular frames 20a, 20b of the seat back frames 16a, 16b. Each seat back frame 16a, 16b also includes a plate 24a, 24b secured to the tubular frame 20a, 20b. Each plate 24a, 24b is made of, for example, metal. Each plate 24a, 24b may have reinforcing ribs, in particular made by stamping.
In addition, the seat base frame 14 herein includes a seat base support portion 26. The seat back support portion 26 is for supporting seat bottom trim, such as foam blocks. The seat base support portion 26 is herein divided into two portions 26a, 26b, each portion corresponding to a respective seat 12a, 12b. Here, the seat base support portion 26 is formed by a frame 28 and stringers 29. The stringers 29 extend along the longitudinal direction X of the seat assembly 10. Thus, the stringers 29 define two portions 26a, 26b of the seat base support portion 26, each portion being specific to a respective seat 12a, 12b of the seat assembly 10.
As shown in fig. 2, the frame 28 is formed of two U-shaped members 30, 32. Here, the U-shaped cores of the two parts 30, 32 form the front and rear cross members of the frame 28, respectively. The lateral branches of the U-shape of the two parts 30, 32 form only a part of one lateral side of the frame 28. Each of the components 30, 32 herein is tubular. Here, each component 30, 32 has a rectangular cross-section, in particular a square cross-section.
The frame 28 comprises two first engagement members 34. As shown in fig. 3, each first engagement member 34 has a U-shaped cross section here in order to accommodate one end of two lateral branches of the U-shaped members 30, 32, which are arranged opposite to each other in the longitudinal direction X. Each first engagement member 34 then defines an interface 36, 38 for securing the two U-shaped members 30, 32. Here, each interface 36, 38 for fastening the U-shaped members 30, 32 takes the form of at least one flat surface of the first engagement member 34, which flat surfaces may be welded to parallel surfaces of the U-shaped members 31, 32, respectively. Preferably, each interface 36, 38 comprises at least two parallel surfaces arranged facing each other, more preferably it comprises a third surface perpendicular to the two parallel surfaces. Alternatively, the interfaces 36, 38 for fastening the U-shaped members 30, 32 may take other forms available to the person skilled in the art, in particular the shape of holes for fastening, for example by means of screws, bolts or rivets. However, welding is preferably used for fastening.
Here, each first engagement member 34 further comprises two holes 40, 42. As shown particularly in fig. 2, each aperture 40, 42 allows for attachment of a respective link 44, 46 and pivoting about a respective transverse axis. Here, each link 44, 46 is fastened at its end opposite the first engagement part 34 to the same anchor member 48 of the first seat assembly 10, which anchor member 48 is fastened to the chassis of the motor vehicle equipped with the first seat assembly 10. Thus, here, two anchor members 48 are implemented to secure the first seat assembly 10 to the chassis of the vehicle, one provided on each side of the seat base frame 14. It should be noted that each or at least one of the anchor members 48 may alternatively be formed by the chassis of a motor vehicle equipped with the seat assembly 10. Each link 44, 46 is pivotally mounted about a respective transverse axis relative to the anchor member 48.
The seat base support portion 26 is attached to the anchor member 48 by the connecting rods 44, 46 such that the first seat assembly 10 can transition from a so-called nominal configuration (allowing accommodation of an occupant on the seat 12a, 12 b) to a reclined or raised configuration, as shown in [ fig. 1], wherein the rear of the seat base frame 14 is raised relative to the nominal configuration. The reclined configuration may correspond to a so-called easy entry configuration, allowing the occupant to access a seat located behind the first seat assembly 10. The tilted configuration may alternatively or additionally allow access to a storage space at least partially underneath the seat assembly 10, which storage space can be realized in particular to hold a spare tire or safety device in case of a tire burst. To maintain the seat assembly 10 in the nominal position, the seat base frame 14 may include a locking device 50 for locking the seat base support portion 26, and in particular the frame 20, to the anchor member 48. Thus, each link 44, 46 forms a functional member of the seat assembly 10 that is adapted to perform a function associated with the seat assembly 10, in which case a passage from the nominal configuration to the reclined configuration of the seat assembly 10 is permitted.
The first engagement member 34 is described in more detail below, with particular reference to fig. 3.
As in figure 3]The first engagement member 34 is shown here extending primarily in the longitudinal direction X of the seat assembly 10. The first engagement member 34 includes a first longitudinal portion 34 having an L-shaped cross-section 1 The first longitudinal portion 34 1 Comprising two perpendicular planes. The first engagement member 34 further includes a first longitudinal portion 34 1 Adjacent second longitudinal portion 34 2 It has an open U-shaped cross section, comprising two parallel faces and a third face connecting the first two faces and perpendicular to the two faces. Second longitudinal portion 34 2 Is adapted to receive one end of the second U-shaped member 32 and allows the first engagement member 34 to be secured thereto by welding to this end of the second U-shaped member 32. Similarly, the first longitudinal portion 34 1 L-shaped cross-section and/or second longitudinal portion 34 2 Is adapted to be applied against the end of the first U-shaped member 30 and allows the first engagement member 34 to be attached thereto by welding. Preferably, however, the first longitudinal portion 34 1 Is not in contact with the first U-shaped member 30 at the first longitudinal portion 34 1 There is no gap with a portion of at least one face (here substantially vertical) between the first U-shaped members 30.
Thus, the first face 52 of the first engagement member 34 1 (here substantially perpendicular) to the two longitudinal sections 34 1 、34 2 Is shared and parallel to the first face 52 1 Is arranged on the second face 52 of (a) 2 Included only in the second longitudinal portion 34 2 Is a kind of medium. First face 52 1 And a second face 52 2 Offset in the transverse direction Y. First face 52 1 Second face 52 2 Through the third face 52 3 (here horizontal) are connected together. As in figure 3]The first hole 40 for securing the first link 44 is shown disposed in the first face 52 1 A second face 52 2 And a first face 52 1 Opposite but not extending. In other words, the first hole 40 for fastening the first link 44 is provided at the first face 52 1 From the second face 52 2 On the longitudinally protruding portion. A second hole 42 for securing the second link 46 passes through the second face 52 2 And (5) forming.
Thus, the two links 44, 46 are here fastened to the first engagement member 34 at points offset in the longitudinal direction X and the transverse direction Y. Thus, the fastening points of the links 44, 46 on the seat base support portion 26 form a trapezoid T, as shown in fig. 4. This configuration of the fastening points of the links 44, 46 on the seat base support portion 26 enables reinforcement of the assembly formed by the seat base portion 26 and the links 44, 46, particularly in the raised configuration of the seat assembly 10. This limits or even prevents movement of the seat base support portion 26 in the transverse direction Y.
Furthermore, as shown in particular in fig. 2, here two links 44, 46 arranged on the same side of the seat assembly 10 are fastened to an anchor member 48 at fastening points which are offset in the longitudinal direction X and in the transverse direction Y. The offset of the fastening point in the transverse direction Y also enables limiting the movement of the seat base portion 26, in particular in the raised configuration.
In particular from figure 5]As can be seen, each link 44, 46 includes two substantially flat portions 44 1 、44 2 、46 1 、46 2 Two portions 44 of the same link 44, 46 1 、44 2 、46 1 、46 2 Extending in two planes P1, P2, here perpendicular, offset in the transverse direction Y. This enables the connecting rods 44, 46 to be reinforced to further limit movement of the seat base portion 26, particularly in the raised configuration of the seat assembly 10, particularly in the transverse direction Y.
In the example shown in fig. 1 and 2, the seat base frame 14 includes a second engagement member 54 similar to the first engagement member 34.
Examples of the second engagement member 54 are shown in fig. 6 and fig. 7.
Here, each of the second engagement members 54 has a shape of an L-shaped corner.
As in figure 6]And [ FIG. 7]]As shown, each second engagement member 54 includes a first portion 54 1 The first portion here extends mainly in the longitudinal direction X of the seat assembly 10. The second engagement member 54 includes a second portion 54 that extends primarily along the transverse direction Y of the seat assembly 10 2 . Finally, a third portion 54 of each second engagement member 54 3 First portion 54 1 Is connected to the second portion 54 2 . First partDividing 54 1 And a second portion 54 2 Has a U-shaped cross section, each cross section comprising two parallel vertical planes and a horizontal plane. Instead, the third portion 54 3 Is corner-shaped, here having an L-shaped cross section. Thus, the third portion comprises two adjacent orthogonal vertical faces, one of which is a longitudinal face and the other of which is a transverse face, and a horizontal face. Preferably, the third portion 54 3 Is spaced from the U-shaped members 30, 32.
First portion 54 1 Is adapted to receive a first length of the U-shaped members 30, 32 and allows the second engagement member 54 to be secured thereto by welding to the first length of the U-shaped members 30, 32. Preferably, only the vertical face of the first portion contacts and is secured to the U-shaped members 30, 32. Similarly, the second portion 54 2 Is adapted to accommodate the length of the U-shaped members 30, 32 and allows the second engagement member 54 to be secured thereto by welding over the length of the U-shaped members 30, 32. Preferably, the second portion 54 2 Is in contact with the U-shaped members 30, 32 and is fastened to the U-shaped members 30, 32.
However, the first portion 54 1 In its vertical plane 56 1 、56 2 On which an interface 58 for fastening the functional component is included 1 -58 6 Each of the functional components is adapted to perform a function associated with the seat 12 of the seat assembly 10. Here, these interfaces 58 1 -58 2 Each taking up a pass-through face 56 1 、56 2 In particular rectangular opening 58 1 Or round hole 58 2 -58 6 In the form of (a). Two faces 56 1 、56 2 By a generally horizontal face 56 3 Are connected together.
In [ FIG. 8]]In the example shown, interface 58 1 -58 6 In particular for fastening:
a locking device 50, which makes it possible to lock the fastening of the frame 28 to the anchoring member 48 in the nominal position of the seat assembly 10. For example, lock 50 is secured by passing through aperture 58 2 -58 3 Is fastened by two bolts;
for fastening the seat back frame 16a,16b, a flange 60. Here, such a flange 60 is provided, for example, by passing through the hole 58 5 、58 6 Is fastened to the second engagement member 54. In the example shown, each flange 60 carries means 18a, 18b for articulating the seat back frame 16a, 16b relative to the seat base frame 14;
the seat belt buckle connection housing 62 or the seat belt retractor. Here, such a housing 62 is formed by passing through the hole 58 4 Is fixed.
Of course, fastening means other than bolts may be realized by means of an interface in the form of an opening, in particular a rivet.
It should also be noted that the interface 58 is in the form of a rectangular opening 1 And not according to the illustrated example. Such an interface 58 1 May be particularly implemented to secure the above-listed devices in other configurations of the seat base frame 14. In particular, the rectangular openings allow the above-described devices to be secured in different positions, allowing their positions to be adapted to different configurations of the frame 28. Thus, the second identical engagement members 54 may be implemented in different frames 28, in particular different sized frames 28. Thus, this limits the number of references required for the frames 28 for different seat assemblies 10.
As in figure 6]And [ FIG. 7]]The first portion 54 of the second engagement member 54 is shown 1 Third face 56 of (2) 3 Here with curvature 62. Such curvature 62 facilitates access to the first portion 54 1 Is provided with an outer face 56 2 Is provided with various interfaces 58 4 -58 6 . Thereby facilitating assembly of the second engagement member 54.
In the example shown, the second portion 54 of the second engagement member 54 2 With a single interface 64 in the form of a rectangular opening in the horizontal plane. Naturally, the second engagement member 54 may have other interfaces in other forms and other locations. In particular, it is conceivable for the second portion 54 to 2 Having at least one interface for securing Isofix wire 66, thereby allowing for the securing of a child seat or other device. The Isofix wire 66 may, for example, be welded into a housing containing the Isofix wire 66 formed in the second portion 54 of the second joint part 54 2 Is a kind of medium.
The second seat assembly 100 is substantially identical to the first seat assembly 10 except that it forms a single seat rather than two seats. The elements of the second seat assembly 100 are identical to those of the first seat assembly 10 and are shown with the same reference numerals without the suffix "a" or "b" as the case may be. These elements are not described in detail below in order to simplify the present description.
The present utility model is not limited to the above examples, and various modifications are possible.
First, in the example shown, the U-shaped members 30, 32 have a closed rectangular or square cross-section. Alternatively, however, these U-shaped members 30, 32 may have an open U-shaped cross-section. In particular, each component 30, 32 may have a cross-section comprising only three faces, which is configured as a U-shape. More generally, each U-shaped member 30, 32 may have an open or closed cross-section, including a plurality of faces, three of which are configured as a U-shape.
Similarly, in the example shown, the engagement members 34, 54 have an open U-shaped cross-section. Such cross-sections facilitate mounting these engagement members 34, 54 on the U-shaped members 30, 32. Thus, each engagement member 34, 54 includes only three faces, configured as a U-shape. Alternatively, however, the engagement members 34, 54 may have a closed cross-section, in particular rectangular, in particular square. More generally, each engagement member 34, 54 may have an open or closed cross-section, including a plurality of faces, three of which are configured in a U-shape.
Further, in the illustrated example, the first and second discrete engagement members 34, 54 are implemented. Alternatively, the first and second engagement members 34, 54 may form one and the same engagement member.
As previously described, the first engagement members 34 for securing the U-shaped members together may produce a set of seat base frames 14 that includes at least the first seat base frame 14 and the second seat base frame 14 as previously described. The two seat base frames 14 may be formed from the same U-shaped member but have different, particularly different, lengths of the first engagement members 34. Thus, different seat base frames, in particular having different dimensions, can be manufactured from the same U-shaped members 30, 32 in order to adapt them to different configurations, e.g. different vehicles and/or different positions.
Finally, in the example shown, two links 44, 46 are fastened to the first engagement member 34. However, other configurations and other kinematics are also possible. For example, three links are pivotally attached to each first engagement member 34. Further, in the depicted example, the links 44, 46 are pivotally mounted relative to the frame of the seat base frame. Alternatively, however, the links 44, 46 may be fixedly mounted relative to the frame of the seat base frame. Even in this case, the links 44, 46 act as feet for the associated seat assembly.
Finally, the seat assembly described above forms two seats. Alternatively, the seat assembly may form a single seat or more than two seats, particularly three seats.
