DETAILED DESCRIPTION

[0054] FIGS. 1, 2A-2B and 3A-3B show a first design variant of a proposed seat assembly 1 for a design variant of a proposed vehicle. In the present case, the seat assembly 1 is shown with two adjacent vehicle seats 1A, 1B which are longitudinally shiftably mounted on a vehicle floor B in a vehicle interior I via a rail arrangement 2. Via the rail arrangement 2, the vehicle seats 1A and 1B are jointly and/or individually adjustable along a (seat) longitudinal direction L via seat rails 2A, 2B of the rail arrangement 2. Each vehicle seat 1A, 1B includes a seat part 10A or 10B fixed to a seat substructure, relative to which a backrest 11A or 11B is pivotally mounted.

[0055] The seat rails 2A and 2B for shiftably mounting the vehicle seats 1A and 1B are arranged below the vehicle floor B. On the vehicle floor B floor slots 20A and 20B are formed, which each extend parallel to the longitudinal direction L and through which a connecting component shiftably mounted on the respectively associated seat rail 2A or 2B protrudes towards the seat substructure of the respective vehicle seat 1A or 1B. In this way, the vehicle seats 1A, 1B can be longitudinally shifted above the vehicle floor B along the seat rails 2A and 2B accommodated below the vehicle floor B.

[0056] Between the two longitudinally extending floor slots 20A and 20B, a third floor slot 20C here is also provided centrally. Below this third floor slot 20C, an additional seat rail can be provided (in particular in the case of a shiftability of the vehicle seats 1A, 1B relative to each other). Alternatively or additionally, the additional third floor slot 20C can serve for shiftably guiding an (additional) accessory for the fixation of components different from the vehicle seats 1A, 1B in the vehicle interior I. This will yet be explained in more detail below.

[0057] In the seat assembly 1 of FIG. 1, the vehicle seats 1A and 1B are adjustably mounted on each rail 2A or 2B in addition via an accessory in the form of a cargo carriage or component carriage 4A, 4B (subsequently briefly: carriage). A seat rail 2A or 2B consequently here also serves the additional guidance of an element different from a vehicle seat 1A or 1B. A carriage 4A, 4B in the present case forms an interface for the fixation of a component different from the vehicle seat 1A or 1B on the vehicle floor B. In the present case, the two illustrated carriages 4A, 4B each are provided behind a vehicle seat 1A or 1B shiftably mounted on the associated seat rails 2A, 2B, with respect to the longitudinal direction L. Via a carriage 4A, 4B for example a part of a load securing system, such as for example a lashing eyelet, a load securing belt or a load securing strap or a cargo container (such as e.g. a cargo box or a cooling box) can be flexibly fixed behind a vehicle seat 1A or 1B. An adjustment position of a carriage 4A, 4B in the present case can be set freely along the respective seat rails 2A or 2B.

[0058] As is illustrated in detail with reference to the enlarged representation of FIGS. 2A and 2B, each carriage 4A, 4B on the respective seat rail 2A or 2B in the present case can be spaced apart as desired along its seat rails 2A or 2B from the respectively associated vehicle seat 1A or 1B along a first adjustment direction V1. If the respective carriage 4A, 4B is not needed, the carriage 4A, 4B can be adjusted in an opposite adjustment direction V2 towards the respective vehicle seat 1A or 1B into a parking position as shown in FIG. 2B. In this parking position, the respective carriage 4A, 4B is protectively accommodated below a cover 3A or 3Bhere formed in the manner of a trim, which is arranged at a rear end of a vehicle seat 1A, 1B so as to cover a part of the vehicle floor B.

[0059] In principle, a carriage 4A, 4B can be longitudinally shiftably mounted on a seat rail 2A, 2B via a slideway and/or roller guide. In the present case, each seat rail 2A, 2B by way of example is designed in the manner of a lower rail on which a base part 40 of a respective carriage 4A, 4B, which in its profile is similar to an upper rail, is shiftably guided. On the base part 40 a plurality of differently oriented guide rollers 401, 402 are rotatably mounted (cf. in particular FIGS. 3A and 3B). The base part 40 and hence the respective carriage 4A, 4B thereby is shiftably guided within the seat rail 2A or 2B and moreover also supported on the seat rails 2A, 2B with forces acting on the outside of the base part 40.

[0060] The respective carriage 4A, 4B in principle can be provided for a manual adjustment along the respective seat rails 2A or 2B. As is illustrated in more detail with reference to FIGS. 3A and 3B, a carriage 4A, 4B in the illustrated design variant each is adjustable in a power-operated way by means of a drive motor 42. By way of example, the drive motor 42 is configured as an electric motor that is coupled with a transmission. For the adjustment, the carriage 4A, 4B here makes use of an adjusting element in the form of a drive spindle that is also used for the (preferably likewise power-operated) adjustment of a vehicle seat 1A or 1B along the respective seat rail 2A or 2B.

[0061] For the adjustment of the carriage 4B by using the drive spindle, the drive motor 42 is coupled with a spindle nut 41 rotatably mounted on the base part 40. This spindle nut 41 meshes with the drive spindle for the vehicle seat 1A or 1B, which in the present case extends over the entire length or at least over a large part of the length of the respective seat rail 2A or 2B. Via its own drive motor 42, a carriage 4A, 4B thus is adjustable along the drive spindle arranged in the seat rail 2A, 2B independently of the vehicle seat 1A or 1B along the respective seat rail 2A or 2B. Of course, however, an adjustment of a carriage 4A, 4B dependent on an adjustment of a vehicle seat 1A, 1B can also be provided alternatively.

[0062] For an independent adjustment relative to the respective vehicle seat 1A or 1B an electronic position detection can be provided. Such a position detection can be adapted and provided for avoiding a collision of the carriage 4A or 4B with the vehicle seat 1A or 1B or a connecting component adjustably mounting the vehicle seat 1A or 1B on the seat rail 2A or 2B and protruding from the respective floor slot 20A or 20B on the vehicle floor B during an adjustment along the seat rail 2A or 2B.

[0063] A carriage 4A, 4B, which in the design variant of FIGS. 3A and 3B is completely integrated into a respective seat rail 2A, 2B designed as a lower rail, in the present case is adapted and provided for the fixation of a component to the vehicle floor B, which component includes a possibly standardized locking element 5 (i.e. each formed identically for locking with each of the carriages 4A, 4B). FIGS. 3A and 3B by way of example show a locking element in the form of a plug-in tongue 5, which at its front, hook-shaped end 2 includes laterally (and hence radially with respect to an insertion direction E) protruding retaining lugs 54. Via these retaining lugs 54, the plug-in tongue 5 can be positively locked in the base part 40 at a locking opening 400. When the plug-in tongue 5 consequently is properly plugged from above the loading floor B into the locking opening 400 at the base part 40 of a carriage 4A, 4B along an insertion direction E, the plug-in tongue 5 can be blocked against being pulled out of the locking opening 400. In this way, different components can be fixed to the vehicle floor B in a comparatively simple way and in particular without any tools at different adjustment positions by means of a carriage 4A, 4B and can also be exchanged when necessary.

[0064] FIG. 3A by way of example shows a component in the form of a load securing belt 6, which is equipped with the plug-in tongue 5 and correspondingly can be positively locked at a carriage 4A, 4B in a simple way in order to be able to secure cargo on a surface of the vehicle floor B behind the vehicle seats 1A, 1B.

[0065] While in the design variant of FIGS. 3A and 3B locking of a plug-in tongue 5 can be effected at the base part 40, a possible development of FIGS. 4, 5A-5B and 6A-6B provides a locking possibility for a plug-in tongue 5 via a locking unit 45 additionally fixed to a base part 40. The locking unit 45 provides a locking mechanism 45.1 at a carriage 4A, 4B above the base part 40 (cf. in particular FIGS. 5A-5B and 6A-6B), which can be pre-mounted and pre-checked separately from the base part 40.

[0066] In addition to a carrier element in the form of a carrier plate 45T, the locking unit 45 is fixed to the base part 40 on which the drive motor 24 is held. The drive motor 24 thereby is held laterally offset from the seat rails 2A, 2Banalogously to the design variant of FIGS. 3A and 3B, so that a drive axis of the drive motor 24 extends perpendicularly to the longitudinal axis L. For an electronic control of the operation of the drive motor 42, FIG. 4 by way of example shows an electronic control unit in the form of a controller 43, which is connected to the drive motor 42 via signal lines and possibly power lines. In addition, a link chain 7 extending along a seat rail 2A, 2B also is outlined in FIG. 4. Via such a link chain 7, an adjustment of the carriage 4A, 4B can be controlled likewise with motoric supportin particular as an alternative to the adjustment by means of a drive spindle.

[0067] The locking of the plug-in tongue 5 at the carriage 4A, 4B in the present case works purely mechanically, but nevertheless automatically. When the plug-in tongue 5 is plugged to the carriage 4A, 4B from above the vehicle floor B, this leads to the displacement of one of several articulated levers 451, 452, 453 of the locking mechanism 45.1 in the direction of an unlocking position, so that the plug-in tongue 5 with a retaining lug 54 can be guided past a blocking portion in the form of a blocking hook 4520 formed on one of the articulated levers. Due to a pretension applied by tension springs 454A and 454B in the direction of a locking position, the blocking hook 4520 automatically snaps into place at a retaining lug 54 of the plug-in tongue 5 as soon as the plug-in tongue 5 has been plugged in sufficiently far in the direction of the base part 40. The blocking hook 4520 then engages behind the retaining lug 54 of the plug-in tongue 5 and thus prevents that the plug-in tongue 5 can be withdrawn from the carriage 4A, 4B in a direction opposite to the original insertion direction E.

[0068] The carriage 4A, 4B of the design variant of FIGS. 4 to 6B furthermore includes a trim element 44 that is accessible on the upper side of the vehicle floor B. A corresponding trim element 44 can also be provided in the design variant of FIGS. 3A and 3B.

[0069] In the design variant of FIGS. 4 to 6B, the locking unit 45 is arranged below the trim element 44, but here in turn below the vehicle floor B, so that from the carriage 4A, 4B on the upper side of the vehicle floor B merely the comparatively flat trim element 45 here oval in the top view is visible and accessible. In particular via the trim element 44 a part of an interface visible and accessible on the upper side of the vehicle floor B here consequently is defined for the fixation of a component including the plug-in tongue 5. The trim element 44 therefor includes an oblong slot for introducing a plug-in tongue 5.

[0070] As is shown in particular in the perspective views of FIGS. 4 and 5A and in the side view of FIG. 5B, the trim element 44 additionally includes a cutout for an actuating element in the form of an actuating knob 450. This actuating knob 450 consequently is accessible for a user on the upper side of the trim element 44. The actuating knob 450 here terminates substantially flush with an upper side of the trim element 44.

[0071] As is illustrated in more detail in particular in the representations of FIGS. 6A and 6B, an actuating force can be introduced into the locking mechanism 45.1 via the actuating knob 450 in order to pivot the articulated lever 452 including the blocking hook 4520 against the restoring forces of the tension springs 454A and 454B from a locking position shown in FIGS. 6A and 6B into an unlocking position. In this unlocking position, the blocking hook 4520 releases the retaining lug 54 of the inserted plug-in tongue 5 and hence permits the extraction of the plug-in tongue 5 against the insertion direction E.

[0072] The locking mechanism 45.1 in the present case is formed with a four-bar linkage. The individual articulated levers 451, 452, 453 consequently are articulated to each other and pivotally mounted via four joint axes. The actuating knob 450 is connected to a first pivotally mounted articulated lever 451, which is coupled with the second articulated lever 452 including the blocking hook 4520 via a joint. This second articulated lever 452 in turn is articulated to a likewise pivotally mounted third articulated lever 453.

[0073] To consequently again release the plug-in tongue 5, a user merely has to press the actuating knob 450 from above. A (sufficiently high) actuating force applied here onto the actuating knob 450 then is converted into pivotal movements of the articulated levers 451, 452, 453 via the locking mechanism 45.1 so that the blocking hook 4520 is pivoted in the direction of its unlocking position and hence away from a retaining lug 54 of the plug-in tongue 5. In this way, the plug-in tongue 5 can again be withdrawn from the carriage 4A, 4Bas long as a user presses down the actuating knob 450.

[0074] In the design variant shown in FIGS. 4 to 6B, the base part 40 has a continuous cutout on its upper side, here in the form of an insertion opening 400*. In contrast to the base-part-side locking opening 400 of the design variant of FIGS. 3A and 3B, locking of the plug-in tongue 5 is not provided at this insertion opening 400*. Rather, the insertion opening 400* in the design variant of FIGS. 4 to 6B in particular serves to provide room for the inserted plug-in tongue 5 so that the same can be plugged in sufficiently far. In this way, the locking unit 45 arranged above the base part 40 can be of comparatively flat design.

[0075] As is illustrated in more detail with reference to FIGS. 7A-7B, 8A-8B and 9, a carriage 4A, 4B not only is usable for the defined connection of components behind the vehicle seats 1A and 1B. One or more carriages 4A, 4B and 4C can also be positioned in front of the vehicle seats 1A and 1B with respect to the longitudinal direction L, in order to be able to thereby fix seat comfort components 6.1, 6.2, 6.3 exchangeable in a simple way to the vehicle floor B.

[0076] In the design variants of FIGS. 7A-7B, 8A-8B ad 9 an individual carriage 4C therefor is provided on the middle floor slot 20C. Below this floor slot 20C a rail, in particular a seat rail, can likewise be provided for the longitudinal adjustment of this carriage 4C. However, this is not absolutely necessary.

[0077] In the design variant of FIGS. 7A-7B, a seat comfort component in the form of a storage box 6.1 with a cup holder is plugged to the middle carriage 4C. Thus, the storage box 6.1 is not fixed to a seat substructure or seating unit of a vehicle seat 1A or 1B, but to the carriage 4C provided on the vehicle floor B, which forms a defined interface for a plug-in tongue 5 that is provided on the storage box 6.1.

[0078] Corresponding to the representation of FIGS. 8A and 8B, the storage box 6.1 can be exchanged against another seat comfort component in the form of a pocket element 6.2 without any tools. Corresponding to the variants explained above, locking with a corresponding plug-in tongue 5 for example can be released in order to subsequently plug the pocket element 6.2 with an identically formed plug-in tongue 5 to the carriage 4C.

[0079] In the design variant of FIG. 9, carriages 4A, 4B on the outer seat rails 2A and 2B also are used in addition to the middle carriage 4C, in order to fix another seat comfort component, here in the form of a footrest 6.1 usable for both vehicle seats 1A, 1B, to the vehicle floor B. Thus, the footrest 6.3 for example includes three plug-in tongues 5 which are plugged to the carriages 4A, 4B and 4C positioned one beside the other along a transverse direction Q extending perpendicularly to the longitudinal direction L.

[0080] The footrest 6.3 fixed in this way to the vehicle floor B comprises two support portions 6.3a and 6.3b which then are arranged in front of the two vehicle seats 1A and 1B so that persons sitting on the vehicle seats 1A, 1B can comfortably support their feet on an associated support portion 6.3a, 6.3b. When carriages 4A, 4B, 4C are longitudinally shiftably mounted along the respective floor slots 20A, 20B and 20C as explained above, the footrest 6.3 (like also a storage box 6.1 and/or a pocket element 6.2) can be longitudinally adjusted relative to the vehicle seats 1A, 1B, but jointly with the vehicle seats 1A, 1B. In particular, a power-operated adjustment of the carriages 4A, 4B, 4C can be made possible via their drive motors 42.

[0081] As illustrated in the design variants of FIGS. 7A to 9, a vehicle interior I thus can be individualized in a particularly simple way with the proposed solution. In the seat assembly 1, the one seat comfort component 6.1, 6.2, 6.3 thus can be exchanged against the other one without any tools depending on the requirement, in particular as desired by a user. The (coupling) interface provided by a carriage 4A, 4B, 4C then allows simple plugging and locking of the respective seat comfort component 6.1, 6.2, 6.3 via one or more inserted plug-in tongues 5.

[0082] In particular, by mounting a carriage 4A, 4B, 4C on one of the seat rails 2A, 2B it furthermore is ensured that forces occurring in operation and also in the case of a crash are reliably introduced into a bodywork component. Via the base part 40 shiftably guided on and in each of the seat rails 2A, 2B, analogously to the combination of upper rail and lower rail known from the seating area, forces can be introduced into the respective seat rail 2A, 2B and hence into a body-mounted vehicle floor assembly. Moreover, it is not absolutely necessary either in this respect that a carriage 4A, 4B, 4C likewise (like an associated vehicle seat 1A or 1B) is adjustable on a seat rail 2A, 2B in a power-operated way. In design variants of the proposed solution, a purely manual adjustment of one or several carriages 4A, 4B or 4C (mounted in particular on a single seat rail 2A or 2B) can be provided.
