Description

Technical Field

[0001] This invention relates to a vehicle seat that is longitudinally and laterally movable, comprising a seat console having a console component fixed to the vehicle and a movable console component, the seat console having adjustment means for moving the vehicle seat in the longitudinal direction and in the lateral direction of the vehicle. The invention also relates to a vehicle, particularly a motor vehicle, having at least one such vehicle seat. Background Technology

[0002] In traditional vehicles, the second-row seats can only move longitudinally within a small adjustment path because the space behind the second-row seats, typically used as a luggage compartment, is narrowed by the rear wheel arches. Especially when the seats are configured as reclining chairs, the second-row seats cannot move further longitudinally into the luggage compartment area, even with current longitudinal adjustment systems. This results in the inability to pass alongside the rear wheel arches by moving only in the longitudinal direction.

[0003] DE102006022732A1 and DE102008004231A1 respectively disclose a seating device for a motor vehicle, wherein the vehicle seat is guided to move along a slide along a track in both the longitudinal and transverse directions of the vehicle. Thus, the vehicle seat automatically moves in the transverse direction as it moves in the longitudinal direction. Here, at least one guide pin on the seat side engages with and moves in a guide groove on the vehicle structure side. The vehicle seat is guided in a longitudinal track, which itself is guided in a transverse track. The vehicle seat can be locked and released from locking by means of an operating mechanism not only in the longitudinal direction but also in the transverse direction at a predetermined stop distance. The overlapping arrangement of the tracks requires a large structural space.

[0004] A vehicle seating device is known from US2018 / 0354391A1, wherein the vehicle seat is movable in the longitudinal direction and in the lateral direction of the vehicle along a track path provided in the bottom of the interior space of the vehicle.

[0005] According to DE102018110414A1, a vehicle seat is suspended on a vertical seat bracket, which itself can move on a circular track path in the bottom of the vehicle's interior space, thereby allowing the vehicle seat to rotate. Summary of the Invention

[0006] The objective of this invention is to provide an improved vehicle seat that can move longitudinally and laterally.

[0007] Therefore, the present invention proposes a vehicle seat that is movable longitudinally and laterally. The vehicle seat includes a seat console having a console component fixed to the vehicle and a movable console component. The seat console has an adjustment device for moving the vehicle seat in the longitudinal and lateral directions of the vehicle. The adjustment device has at least one first guide section extending in the longitudinal direction of the vehicle with a directional component and at least one second guide section extending in the lateral direction of the vehicle with a directional component. The seat console is provided with a coupling device configured to couple the movable console component and the console component fixed to the vehicle to each other. The at least one first guide section and the at least one second guide section are located in a common plane. The first and second guide sections are constructed on or in a groove, wherein the groove has a groove track configured as a slot or groove, and the adjustment device has at least one groove guide element. The sliding guide element is configured to be guided along the direction of the sliding groove, wherein the sliding groove has a first outer edge region with a first guide rail and a second outer edge region with a second guide rail, the second guide rail being opposite to the first guide rail, wherein the first and second guide rails extend parallel to each other in partial sections and parallel to the sliding groove rail located between them, and respectively constitute at least one of the first and second guide sections, the adjusting device having at least one first guide element belonging to and cooperating with the first guide rail and at least one second guide element belonging to and cooperating with the second guide rail, the first guide element and the second guide element being spaced apart from each other such that the first guide element and the second guide element always simultaneously abut against the first and second guide rails respectively belonging to them.

[0008] A vehicle seat capable of longitudinal and lateral movement includes a seat console having a console component fixed to the vehicle and a movable console component. The seat console has adjustment mechanisms for moving the vehicle seat in the longitudinal and lateral directions of the vehicle. The adjustment mechanisms have at least one first guide section extending in the longitudinal direction of the vehicle with a directional component and at least one second guide section extending in the lateral direction of the vehicle with a directional component. The seat console is provided with a coupling device configured to couple the movable console component and the console component fixed to the vehicle to each other, and the at least one first guide section and the at least one second guide section... The segments are located in a common plane, wherein the guide segments are constructed on or in a chute, wherein the chute has a chute track configured as a slot or groove, and the adjusting device has at least one chute guide element (e.g., a slider) that can be guided along the direction of the chute, characterized in that the chute has a first outer edge region with a first guide track and a second outer edge region with a second guide track opposite to the first guide track, wherein the two guide tracks extend parallel to each other and parallel to the slider track located between them in a partial section and respectively constitute at least one guide segment of the guide segments.

[0009] On the outer edge region of the slide, guide rails that are parallel to each other and parallel to the slide track are provided, which not only guide the seat point by point in the slide track, but also additionally guide the seat on the guide rails, so that the seat maintains a defined orientation during movement.

[0010] Here, the guide rail on the outer edge region of the slide serves as the seat rail. While the lateral orientation of the slide, with at least one directional component, includes an abrupt transition from longitudinal guidance to lateral guidance perpendicular to the longitudinal adjustment direction, a gradual transition from longitudinal to lateral guidance is preferred because this results in a smaller lateral force pulse acting on the passenger seated in the vehicle. Therefore, it is advantageous that the lateral movement of the vehicle seat is always accompanied by continuous longitudinal movement.

[0011] advantage

[0012] According to the present invention, the chute guide device includes not only a chute guide device that guides the vehicle seat along the chute's direction, but also a guide device for the seat having the same track oriented around its vertical axis, eliminating the need for additional seat tracks. This saves structural space and height. Furthermore, the vehicle seat according to the present invention has a coupling device that can couple a movable console component to a console component fixed to the vehicle and is used to lock the vehicle seat.

[0013] In the prior art, locking devices for both longitudinal and lateral adjustment, and which typically must be located on one of the lateral and one of the longitudinal tracks, are integrated into the slide guide device according to the present invention. This eliminates the need for only one locking device, thus reducing costs. Here, the slide rail or guide rail may have coupling sections. In this way, although both the guiding and locking functions are implemented in the slide guide device, they are still spatially separated from each other there.

[0014] Preferably, the adjusting device has at least one first guide element that is associated with and cooperates with the first guide rail and at least one second guide element that is associated with and cooperates with the second guide rail.

[0015] Advantageously, the first guide element and the second guide element are spaced apart from each other such that they are always simultaneously abutting against their respective guide rails.

[0016] Preferably, the chute is configured in an L-shape, wherein the first track section of the first guide rail, the first track section of the second guide rail, and the first chute track section are constructed on or in the first leg of the chute, which extends substantially parallel to the longitudinal direction of the vehicle, and the second track section of the first guide rail, the second track section of the second guide rail, and the second chute track section are constructed on or in the second leg of the chute, which extends substantially parallel to the lateral direction of the vehicle.

[0017] In a preferred further improvement of the invention, the coupling device has at least one coupling section disposed in or on the slide and a coupling element, wherein the coupling device is configured such that the coupling element can engage with the coupling section for coupling.

[0018] In another preferred further improvement of the invention, which can be combined with other embodiments, the coupling device is part of an electric drive device for the regulating device.

[0019] Here, the at least one coupling section is configured as a friction surface track, and the coupling element is configured as a friction wheel capable of engaging with the friction surface track.

[0020] Preferably, however, the at least one coupling section is configured as a rack device, and the coupling element is configured as a gear capable of engaging with the rack device.

[0021] Not only the friction wheel solution, but also the rack solution, can reliably lock the vehicle seat and is suitable for applying the driving force of an electric drive device that drives the friction wheel or gear as the drive wheel to the groove, thereby causing the vehicle seat to move like a motor.

[0022] A particularly advantageous design of the vehicle seat according to the invention is characterized in that a first coupling section, formed by a first rack of the rack assembly extending in the longitudinal direction of the vehicle, and a second coupling section, formed by a second rack of the rack assembly extending in the transverse direction of the vehicle with at least a directional component, are constructed on two abutting sides of the slide rail. The drive mechanism for the gear meshing with the rack of the rack assembly is preferably controlled such that a soft stop is inserted before a change in the direction of movement of the seat. That is, the movement in the first direction is slowly braked before movement in the second direction of movement. This avoids an uncomfortable, sudden acceleration for the passenger sitting in the vehicle seat when the direction of movement changes.

[0023] The present invention also relates to a vehicle, particularly a motor vehicle, having at least one vehicle seat constructed according to the present invention. Attached Figure Description

[0024] The following describes in detail, with reference to the accompanying drawings, various preferred embodiments of the invention, which have additional design details and other advantages.

[0025] in:

[0026] Figure 1 A vehicle seat according to the invention is shown; and

[0027] Figure 2 An exemplary embodiment of the slide guide device for a vehicle seat according to the present invention is shown. Detailed Implementation

[0028] Figure 1 The vehicle seat 1 is shown in a side view. This vehicle seat is mounted on the floor 14 of the vehicle's interior space (not shown further in other contexts) via a seat console 10. The seat console 10 has a console component 11 fixed to the vehicle and connected to the floor 14 of the interior space, and a movable console component 12 connected to the vehicle seat 1. The two console components 11, 12 are movable relative to each other and guided to each other by means of an adjustment device 2, as they are subsequently... Figure 2 As described.

[0029] The adjustment device 2 has a slide 4 connected to the console component 11 fixed to the vehicle in the example shown. This slide 4 is configured in an L-shape and has a first leg 4' extending substantially parallel to the longitudinal direction X of the vehicle and a second leg 4' extending substantially parallel to the lateral direction Y of the vehicle. The L-shaped shape of the slide 4 is shown here only as an example. The slide 4 can also be configured in any other shape with a first leg extending in the longitudinal direction of the vehicle with a major directional component and a second leg extending in the lateral direction of the vehicle with a major directional component.

[0030] The chute 4 has a chute track 40 configured as a slot or groove, the chute track having a first chute track section 40' extending parallel to the vehicle's longitudinal direction X and a second chute track section 40" extending parallel to the vehicle's lateral direction Y. The two chute track sections 40', 40" may also be slightly deviated from their parallelism relative to the vehicle's longitudinal direction X or relative to the vehicle's lateral direction Y by, for example, a few degrees.

[0031] The two legs 4' and 4" of the slide 4 form a first outer edge region 41 and a second outer edge region 43 on their opposite longitudinal sides. A first guide rail 42 for cooperating with a first guide element 45 is provided on the first outer edge region 41, and a second guide rail 44 for cooperating with a second guide element 46 is provided on the second outer edge region 43. The two guide rails 42 and 44 extend parallel to each other and parallel to the slider rail 40 located between them in a partial section, wherein the guide rails 42 and 44 are opposite to each other relative to the slide rail 40.

[0032] Guide rails 42 and 44 respectively form guide sections 20 and 22 of the adjustment device 2 and are used to guide the vehicle seat 1 when the movable console component 12 of the vehicle seat 1 moves. Here, the first guide section 20 is composed of a first rail section 42' of the first guide rail 42 extending parallel to the longitudinal direction X of the vehicle and a first rail section 44' of the second guide rail 44, and the second guide section 22 extending parallel to the lateral direction Y of the vehicle is composed of a second rail section 42" of the first guide rail 42 and a second rail section 44" of the second guide rail 44. Similarly, the slide rail 40 is formed with a first slide rail section 40' extending in the longitudinal direction X of the vehicle and a second slide rail section 40 extending in the lateral direction Y of the vehicle.

[0033] The first guide element 45 and the second guide element 46 are connected to the movable control console component 12. The two guide elements 45 and 46 are spaced apart from each other not only in the longitudinal direction X of the vehicle but also in the lateral direction Y of the vehicle, such that they always simultaneously abut against their respective guide rails 42 and 44. In other words, the distance between the sides 45' and 46' of the corresponding guide elements 45 and 46 in the longitudinal direction X of the vehicle corresponds to the width a of the second leg 4” of the chute 4 measured in the longitudinal direction X of the vehicle, and the distance between the sides 45” and 46” of the corresponding guide elements 45 and 46 in the lateral direction Y of the vehicle corresponds to the width b of the first leg 4’ of the chute 4 measured in the lateral direction Y of the vehicle.

[0034] The seat console 10 also includes a coupling unit 3 configured to couple the movable console component 12 to the console component 11 fixed to the vehicle. The coupling unit 3 has a coupling element 48 connected to the movable console component 12 and a coupling region 47 disposed on the slide rail 4, wherein the coupling element 48 can engage with the coupling region 47 for coupling. For this purpose, the coupling region 47 of the slide rail 4 is configured as a rack device 49, which, as a first coupling segment 47', has a first rack 49' extending in the longitudinal direction X of the vehicle and disposed on the longer inner side of the first slide rail segment 40', and the rack device, as a second coupling segment 47', has a second rack 49' extending in the transverse direction Y of the vehicle and extending on the longer inner side of the second slide rail segment 40'. Therefore, the first rack 49' constructed on the first coupling section 47' and the second rack 49" disposed on the second coupling section 47" abut against each other and form an interior angle between them, which is 90° in the example shown.

[0035] The coupling element 48 is configured as a gear 48', which engages with the racks 49', 49" of the rack assembly 49. The gear 48' is connected via a gear shaft 48" to an electric drive 30 for the adjusting device 2, thereby allowing the gear 48' to be rotated by the electric drive 30. Depending on the direction of rotation, the gear 48' then rolls on the racks 49', 49" of the rack assembly 49 in one direction or another. Here, the teeth of the racks 49', 49" are arranged such that the gear 48' can roll from one rack to the other without protrusion at the point where the two racks 49', 49" meet.

[0036] When gear 48' rolls along the rack 49', 49" of rack assembly 49, the gear drives drive unit 30, which is connected to movable console component 12 and thus to vehicle seat 1, via rack shaft 48" so that vehicle seat moves along slide 4 fixed to vehicle in the vehicle lateral direction Y or in the vehicle longitudinal direction X.

[0037] This invention is not limited to the above embodiments, which are only used to generally illustrate the core ideas of the invention. Within the scope of protection, the device according to the invention can also take different design forms than those described above. In particular, the device can have the following features, which are combinations of the corresponding individual features of the claims.
