    [0001] The present invention relates to a car seat, especially a utility vehicle seat, with the characteristics of the preamble of claim 1. State of the art
    [0002] From the document DE 10 2006 059 088 B4, a car seat of this kind has become known, which can be adjusted in height by means of a bifurcated chassis.
    [0003] The bifurcated chassis comprises a lower frame, an upper frame positioned on top and, on each side, a pair of crossed rockers. The rockers in the bifurcated chassis are interconnected in pairs through several transversal tubes. In the rear area of the vehicle seat, the rockers are articulated, using transversal tubes in the lower frame as well as in the upper frame.
    [0004] In the front area of the vehicle seat, support devices are provided, by means of which the rockers are moved in the upper frame as well as in the lower frame, in a longitudinal direction. These support devices feature two rotating rollers that cooperate with conduits in the upper frame, as well as in the lower frame.
    [0005] In the event of a change in the height of the bifurcated chassis, the rollers move under corresponding conditions in the upper frame as well as in the lower frame, in the longitudinal direction. In this case, each of the rollers of a support device moves in an upper direction and the other roller moves in a lower direction.
    [0006] An automobile seat of this kind has also come to be known from US 6,200,032 B1. To reduce the gap, especially in the vertical direction, two rollers with different diameters are provided, the inner roll having a larger diameter than the outer roll. Assignment
    [0007] The object of the present invention is to improve a car seat of the kind initially mentioned, especially to indicate an alternative configuration to reduce the gap. Solution
    [0008] According to the invention, this task will be solved by a car seat with the characteristics mentioned in claim 1. Advantageous configurations, which can be used individually or in combination, reciprocally, are the subject of the dependent claims.
    [0009] An automobile seat of this kind, especially a utility vehicle seat, comprises a bifurcated chassis for height adjustment that features interlocking rockers and at least one frame, as well as at least one support device by means of which one of the rockers is driven with mobility within the frame, with the support device having a load roller that can be rotated around a support axis, which cooperates with a first drive, and a compensation roller, which can be rotated around the support axis, that cooperates with a second conduction.
    [0010] According to the invention, it is provided that the second conduction for the compensating roller is arranged in a basic area of a feeder and a side area of this feeder, which extends at right angles to the base area, is attached in the frame, and / or a top area of the feeder, which extends in parallel to the basic area, is attached to the frame, and the basic area is configured elastically deformable, pressing against the compensating roller.
    [0011] The basic area, due to its elasticity and prestressing, presses with the second conduction against the compensating roller, with which the loading roller will be pressed against the first conduction. In this way, between the conduits and the loading roller, as well as the compensating roller, the clearance there is reduced, that is, eliminated.
    [0012] A simple assembly of the feeder results when the frame has an open C-profile towards the interior of the car seat, which profile includes an upper flank, a lower flank that projects in parallel with the upper franc, and a basic flank that projects at right angles to the upper flank, the basic flank interconnecting the upper flank with the lower flank, the side area being attached to the basic flank, preferably by means of welding and / or the area of the top is attached to the upper flank, preferably by means of welding.
    [0013] The feeder preferably also has an open C-profile, making assembly even simpler.
    [0014] In this case, the area at the top of the feeder advantageously constitutes the first conduction for the loading roller.
    [0015] The alignment of the feeder in the frame assembly is simplified by the fact that the top area extends in parallel to the upper flank, being juxtaposed on the upper flank.
    [0016] Advantageously, the basic area is arranged in parallel, or at least in parallel, over a large extent, in the direction of the lower flank, with a gap between the basic area and the lower flank. In this way, an elastic deformation of the basic area in the direction of the lower flank is possible, in the same way as in the direction of the removal of the lower flank.
    [0017] According to an advantageous embodiment of the invention, the basic area comprises a first segment, which is sequential to the lateral area, as well as a second segment that is distant in relation to the lateral area, the second segment being configured similarly to a compression stage, being arranged out of phase parallel to the first segment. The compression stage ensures a necessary distance between the first segment and the loading roller, in order to avoid contact of the basic area with the loading roller.
    [0018] Preferably, the second segment will also constitute the second conduction for the compensating roll.
    [0019] According to another advantageous embodiment of the invention, in the basic area a support is mounted which constitutes the second conduction for the compensating roller. In this case, the support ensures the necessary distance between the first segment and the load roller in order to avoid contact of the basic area with the load roller.
    [0020] Preferably, the feeder is made of metal, preferably steel. This makes it possible to weld the feeder with the frame and provide the basic area with the necessary elasticity at the same time. Figures and Modalities of the Invention
    [0021] In the following, the invention will be explained in more detail on the basis of advantageous modalities, presented in the drawings. However, the invention is not restricted to these execution examples. The Figures show:

    [0032] A seat 1 for a utility vehicle has a bifurcated chassis 3, which comprises a lower frame 5, an upper frame 7, arranged above the lower frame, and, on each side, a pair of first rockers 8a and second rockers 8b intertwined. A transverse tube 9 interconnects the two points of the intersection and simultaneously defines an axis of the bifurcated section, around which the rockers 8a and 8b can rotate relative to each other.
    [0033] The arrangement of the car seat 1 inside the vehicle, and its common direction of travel define the direction indications that will be used next. In this case, a direction oriented perpendicularly to the ground will then be referred to as the vertical direction and a direction perpendicular to the vertical direction and perpendicular to the direction of travel will then be referred to as the transverse direction.
    [0034] The first rockers 8a are interconnected at their rear ends through a retaining tube 18, being articulated in the upper frame 7. At their front ends, the first rockers 8a are interconnected through a support tube 20, being conducted bilaterally by support devices 21, on both sides, inside the lower frame 5 in a longitudinal direction that corresponds approximately to the direction of travel.
    [0035] The second rockers 8b are interconnected at their rear ends through a retaining tube 18, being articulated in the lower frame 5. At their front ends, the two rockers 8b are also interconnected through a support tube 20 and, in the two sides, with support devices 21, are moved in a longitudinal direction in the upper frame 7.
    [0036] The transverse tube 9, the support tubes 20 and the retainer tubes 18 in the present case extend in the transverse direction, in the same way as the axis of the bifurcated section. By rotating the first rockers 8a with respect to the second rockers 8b around the axis of the bifurcated section, the height of the upper frame 7 over the lower frame 5 is changed, hereinafter referred to as the height of the bifurcated chassis 3. By means of a shock absorber 12 and, preferably, a shock absorber, not shown here, the bifurcated chassis 3 becomes a system with oscillating capacity that considerably increases the comfort of the seat.
    [0037] The car seat 1 also has a seat frame 6, which, on the one hand, is articulated on both sides in its rear area in the upper frame 7 and, on the other hand, in its front area, by by means of a tilt regulator, it can be suspended and lowered, and therefore its inclination in relation to the bifurcated structure can be adjusted 3.
    [0038] The car seat 1 also has a backrest 10 which, in the present case, is mounted on the frame of the seat 6, adjustable in inclination. Alternatively, the backrest 10 can also be mounted on the top frame 7. The backrest 10 has a coating 28. In a top area of the backrest 10, in a vertical direction, a headrest 40 is provided. The backrest 10 and the frame of the seat 6, which comprises a seat cushion, constitute a seat component 2.
    [0039] The seat component 2, together with the forked chassis 3, can be moved through two pairs of rails, with which the car seat 1 can be adjusted in a translational direction, in the longitudinal direction, which corresponds, approximately, to the direction of travel. In this case, the two pairs of rails are offset in a transverse direction, in a convergent direction, being arranged reciprocally in parallel. Essentially, the two pairs of rails are of identical constitution.
    [0040] Each rail stop comprises a first seat rail 45 which will also be designated as the top rail, as well as a second seat rail 46 which will also be designated as the lower rail. In the present case, the second seat rail 46 is firmly attached to the vehicle frame and the first seat rail 45 is firmly attached to the lower frame 5 of the car seat 1. Alternatively, one can imagine interconnecting the second seat rail 46 through an adapter or a console, with the structure of the vehicle itself. In addition, it is possible to imagine joining the first seat rail 45, by means of an adapter, with the lower frame 5 of the car seat 1.
    [0041] In this case, the first seat rail 45 is relative and movable within and in relation to the second seat rail 46. Using a locking device, the first seat rail 45 can be locked with the second rail seat 46. An unlocking unit, which includes an unlocking handle 44, serves to unlock the locking device.
    [0042] The release handle 44 is arranged in a front area of the car seat 1, in the direction of travel, that is, in the longitudinal direction, being mounted rotatable around a turning axis, in this case, in a transverse direction . By means of traction applied to the release handle 44 in the upward vertical direction, this handle will be rotated around the axis of rotation with which the locking device will be unlocked.
    [0043] The release lever 44 and the pivot axis are kinetically allocated to the lower frame 5, as well as to the first seat rail 45. This means that when the seat section 2 is displaced in the longitudinal direction, the release lever 44 follows this movement correspondingly, however, not when there is a change in the height of the bifurcated chassis 3, that is, when the seat section 2 moves in a vertical direction.
    [0044] Each of the sections of the upper frame 7, as well as of the upper frame 5, which protrudes in the longitudinal direction, each have an open C-profile towards the interior of the car seat 1. Each support device 21 has a load roller 14 which is pivotally mounted around a support axis 16 which projects in a transverse direction and extends within an open C-profile of the upper frame 7 or the lower frame 5.
    [0045] The C-profile of the upper frame 7, as well as the C-profile of the lower frame 5, each comprise an upper flank 30, as well as a lower flank 32 which is arranged in the vertical direction below the upper flank. The upper flank 30 and the lower flank 32 converge in a parallel direction and are interconnected through a basic flank 34 which extends at a corresponding right angle. In this way, the upper flank 30, the lower flank 32 and the basic flank 33 form a C-profile in cross section.
    [0046] The load roller 14 of the support device 21 is pivotally mounted on a cylindrical support tree 24. The support tree 24 is firmly connected with the support tube 20, the central axes of the support tube 20 and the support tree 24 being reciprocally aligned, constituting the support axis 16 of the load roller 14. In the present case , the loading roller 14 is of approximately cylindrical configuration.
    [0047] In addition, a compensating roller 36 is mounted on the cylindrical support tree 24, being rotatable around the supporting axis 16. Also, in the present case, the compensating roller 36 is of approximately cylindrical configuration. In the present case, the compensating roller 36 has the same diameter as the loading roller 14.
    [0048] In the present case, the load roller 14 is arranged in a transversal direction on the external part of the support tree 24, that is, it is facing in the direction of the basic flank 34 of the C-profile. The compensating roller 36 is arranged in the transverse direction within the support tree 24, that is, it is facing towards the support tube 20.
    [0049] Within the C-profiles of the upper frame 7 as well as the lower frame 5 are fitted feeders 60 that also have a cross section approximately in C shape. Each feeder 60 has a top area 50, a base area 52 and a side area 54, joined with the top area 50 and the base area 52. The top area 50 is arranged in parallel to the upper flank 30, the basic area 52 is arranged to the greatest extent in parallel with the lower flank 32 and side area 54 is arranged parallel to the basic flank 34 of the C-profile.
    [0050] The top area 50 slopes, juxtaposedly, on the upper flank 30, while between the basic area 52 and the lower flank 32 there is a gap. The side area 54 is welded with the basic flank 34 of the C-profile, in this case by laser welding.
    [0051] The basic area 52 comprises a first segment 62, sequential to the side area 54, as well as a second segment 64, sequential to the first segment 62, being remote from the side area 54. The first segment 62 and the top area 50, in a vertical direction, are arranged approximately in a reciprocally opposite direction, facing each other.
    [0052] According to a first example of execution, shown in Figures 3 and 4, and a second example of execution, shown in Figures 5 and 6, the second segment 64 is configured like an embossing step, being approximately , in parallel and out of phase with the first segment 62. In this case, the first segment 62 is closer to the lower flank 32 than the second segment 64.
    [0053] The top area 50 forms a first conduction for the loading roller 14 and the second segment 64 of the basic area 52 forms a second conduction for the compensating roller 36. The stamping step format ensures that the compensating roller 36 is in contact with the second segment 64 of the basic area 52, while the loading roller 14 is spaced, in a vertical direction, from the first segment 62 of the basic area 52.
    [0054] In the present case, the feeder 60 is made of steel and is therefore elastic. In particular, the base area 52 is elastic and therefore acts in a similar way to a spring. In this case, the second segment 64 presses in an upward vertical direction against the compensating roller 36. In this procedure, the loading roller 14 will be pressed in an upward direction, against the top area 50.
    [0055] In this way, it is ensured that the compensating roller 36 and the loading roller 14 have permanent contact with the corresponding conduits, leaning against the first conduction, as well as the second conduction. In this way, tolerances between components can be compensated and the clearance in the vertical direction will be eliminated.
    [0056] To compensate for clearance in the transverse direction, according to the first example of execution shown in Figures 3 and 4, it serves an extended section 72, configured on the load roller 14. The extended section 72 is on the front side of the load roller 14, facing towards the side area 54 of the feeder 60, and protrudes, in a transverse direction, the remaining part of the load roller 14. The extended section 72 abuts the side area 54 of the feeder 60. The section 72, in the present case, is configured as a spherical projection in the shape of a spherical segment on the front side of the loading roller 14. Other configurations can also be imagined.
    [0057] According to the second example of execution, shown in Figures 5 and 6, in order to compensate for a gap, a sliding element 70 is disposed, in a transverse direction, which is inserted in a support hole in the support tree 24, which protrudes in the transverse direction. The sliding element 70 abuts, in this case, on the side area 54 of the feeder 60.
    [0058] According to a third example of execution presented in Fig. 7, Fig. 8 and Fig. 9, the second segment 64 is sequential, in a straight line, to the first segment 62. In the second segment 64 of the basic area 52 is a support 66 is mounted, in the present case being glued, and which constitutes the second conduction for the compensating roller 36, while the top area 50 constitutes the first conduction for the loading roller 14. By the support 66 it is ensured that the roller compensator 36 is in contact with the second conduction, while the loading roller 14 is spaced, in a vertical direction, from the first segment 62 of the basic area 52.
    [0059] In the present case, the second support 66 is made of a hard plastic, inelastic or with little elasticity. It can also be imagined that the support 66 is made of an elastic material, for example, rubber.
    [0060] Also in the third example of execution, the feeder 60 consists of steel and is therefore elastic. In particular, the basic area 52 is elastic and therefore acts similar to a spring. In this case, the second segment 64 with the support 66 presses perpendicularly upwards against the compensating roller 36.The loading roller 14 will be pressed upwards against the top area 50.
    [0061] Thus, it is also ensured in the third example of execution that the compensating roller 36 and the loading roller 14 have constant contact with the corresponding conduits, leaning against the first conduction as well as the second conduction. In this way, component tolerances can be compensated, and the vertical clearance will be eliminated.
    [0062] According to the third execution element, shown in Fig. 7, Fig. 8 and Fig. 9, to compensate for the clearance in the transverse direction, it serves - according to a third example of execution - a sliding element 70 that is inserted in a support perforation within the support tree 24 that projects in a transverse direction and that touches the side area 54 of the feeder 60, similar to the second example of execution, shown in Fig. 5 and Fig. 6.
    [0063] It is also possible to imagine, to compensate for the play in the transverse direction, similar to what occurs in the first example of execution, shown in Figures 3 and 4, to mount on the load roller 14 an enlarged section that is on the front side of the loading roller. load 14, facing towards the side area 54 of the feeder 60, and extending, in a transverse direction, the remaining part of the load roller 14. The extended section will then rest against the side area 54 of the feeder 60.
    [0064] In the execution examples described here, the support devices 21 that cooperate with the lower frame 5, correspond, in their structure and function, to those of the support devices 21 described here in the upper table 7. Fig. 7 presents a part of a car seat with a support device 21 in the upper frame 7 and in the lower frame 5.
    [0065] The characteristics described in the present description, in the claims and in the drawings, may be important, both individually, as well as in combination, for the embodiment of the invention in its different modalities.
