Description

Adjustable seating arrangement and vehicle

[0001] The invention relates to an adjustable seat arrangement with a bench seat having a plurality of seating surfaces and at least one or more backrests or optionally with a one-piece bench seat backrest and a vehicle with such a seat arrangement. State of the art

[0002] Seating arrangements for a vehicle are generally known. For example, a vehicle may comprise a number of adjustable individual seats for a rear row of seats, particularly a second or third row of seats, and a bench seat with one or more backrests in a rear row of seats. Task

[0003] The invention is based on the object of improving a seating arrangement of the type mentioned at the beginning and of providing a corresponding vehicle. Solution

[0004] The first-mentioned object is achieved according to the invention by a seat arrangement having the features of claim 1. The second-mentioned object is achieved according to the invention by a vehicle having the features of claim 10.

[0005] Further developments of the invention are the subject of the dependent claims.

[0006] The seat arrangement according to the invention comprises a seat part with a plurality of seating surfaces (also called a seat bench with a plurality of seating surfaces) and with at least one backrest or a plurality of backrests, wherein for the adjustment, in particular for the longitudinal adjustment, of the seat arrangement, in particular of the seat part or the seat bench, an adjustment arrangement is provided which comprises a combination of electrical longitudinal adjustment devices and at least one manual longitudinal adjustment device which are configured and interact with one another in order to adjust the seat arrangement, in particular the seat part or the seat bench, in the longitudinal direction and to lock it in a sitting position (also called the sitting longitudinal position).

[0007] For the purposes of the invention, a seat section is understood to be a single seat section with multiple seating surfaces for multiple users. Such a seat section, designed to accommodate multiple users, is also referred to as a bench or multi-seat bench.

[0008] Because the adjustment arrangement comprises a combination of electric longitudinal adjustment devices and manual longitudinal adjustment devices, the seat arrangement designed as a multiple seat bench can be easily adjusted electrically and, at the same time, be designed to absorb high loads. By means of the electric longitudinal adjustment devices, in particular electromotive longitudinal adjustment devices, the seat part or the seat bench can be adjusted in the longitudinal direction, in particular continuously. By means of the manual longitudinal adjustment devices, the seat part or the seat bench can additionally be locked in a seating position. For example, when the manual longitudinal adjustment device is unlocked, the seat part or the seat bench can be adjusted in the longitudinal direction (also called longitudinally adjusted) by means of the electric longitudinal adjustment devices.For example, the manual longitudinal adjustment devices can be unlocked via actuators. The seat section or bench seat is then adjusted longitudinally using the electric longitudinal adjustment devices, for example, automatically via an unlocking signal. Alternatively, a user can unlock the manual longitudinal adjustment devices, and the longitudinal adjustment of the seat section is then performed automatically, for example, via an unlocking signal, using the electric longitudinal adjustment devices.

[0009] The seat, in particular a multiple-seat bench, for example a triple-seat bench, comprises at least three, preferably four, longitudinal adjustment devices arranged parallel to one another and in contact with one another. For example, the adjustment arrangement can comprise at least two outer electric longitudinal adjustment devices and at least one or more, preferably two, inner manual longitudinal adjustment devices.

[0010] Preferably, for example, the adjustment arrangement for a triple seat bench can comprise exactly three longitudinal adjustment devices with two outer electric longitudinal adjustment devices and one inner manual longitudinal adjustment device, or exactly four longitudinal adjustment devices with two outer electric longitudinal adjustment devices and two inner manual longitudinal adjustment devices. The inner manual longitudinal adjustment device(s) is / are arranged between the two outer electric longitudinal adjustment devices.

[0011] For example, the two outer electrical longitudinal adjustment devices are configured to absorb a lower load than the inner manual longitudinal adjustment device(s). In particular, the two outer electrical longitudinal adjustment devices can be configured to absorb a load in a range of up to a maximum of 60 kN, in particular a longitudinal load of up to 40 kN and / or a peeling load of up to 60 kN. The at least one inner manual longitudinal adjustment device can be configured to absorb a load in a range of greater than 35 kN up to a maximum of 120 kN, in particular a longitudinal load of up to a maximum of 65 kN and / or a peeling load of up to a maximum of 100 kN.

[0012] The at least one manual longitudinal adjustment device can also be provided with an integrated belt holder.

[0013] For example, the at least one manual longitudinal adjustment device can comprise a locking device for locking the seat in a seating position, in particular incrementally over the entire adjustment range, in the longitudinal direction. The locking device can be designed, for example, as a claw lock.

[0014] The respective longitudinal adjustment device comprises a pair of rails with a floor rail (also called lower rail or second rail element) and a seat rail (also called upper rail or first rail element), which are displaceable relative to one another in a longitudinal adjustment direction. The respective longitudinal adjustment device can have guide means via which the floor rail and the seat rail are guided relative to one another. In other words: both the respective electric longitudinal adjustment device and the respective manual longitudinal adjustment device comprise a pair of rails with a floor rail and a seat rail, which are displaceable relative to one another in the longitudinal adjustment direction. In particular, the seat rail is movably mounted in or on the, in particular stationary, floor rail, in particular arranged so as to be longitudinally adjustable. The seat rail is also referred to as a slider or glider.

[0015] The electrical longitudinal adjustment devices can, for example, have a spindle drive for electrical longitudinal adjustment.

[0016] In summary, and in other words, the invention provides a seat arrangement designed as a multi-seat bench that is electrically adjustable and lockable in one increment over the entire adjustment range of the seat bench. The two outer, less loaded longitudinal adjustment devices are electrical longitudinal adjustment devices, for example, electrical rails. The at least one inner, highly loaded longitudinal adjustment device is a manual longitudinal adjustment device, in particular a manual rail.

[0017] An electric longitudinal adjustment device is understood, in particular, to be a rail arrangement adjustable by means of an electric drive. In particular, the two outer electric longitudinal adjustment devices are designed as rail assemblies, each of which is longitudinally adjustable by means of an associated electric drive, for example, a spindle drive. To enable uniform longitudinal drive for the seat arrangement, the longitudinal adjustment devices are designed symmetrically. In particular, the two outer electric longitudinal adjustment devices have identical electric drives in size and type, which are signal-coupled to each other for their synchronous control and activation.

[0018] A manual longitudinal adjustment device is understood, in particular, to mean a manually adjustable rail arrangement. For example, the electric longitudinal adjustment device and the manual longitudinal adjustment device are coupled to one another via the seat part or the seat bench. In particular, the electric longitudinal adjustment devices and the at least one manual longitudinal adjustment device are motion-coupled to one another via the seat part or the seat bench. For example, the electric longitudinal adjustment devices and the at least one manual longitudinal adjustment device are motion-coupled to one another in such a way that when the electric longitudinal adjustment devices, in particular their seat rails, are actuated and adjusted in the longitudinal direction, the at least one manual longitudinal adjustment device is automatically actuated (co-actuated) and adjusted (co-adjusted) in the longitudinal direction, in particular its movable seat rail is moved along. Figures and embodiments of the invention

[0019] The invention is explained in more detail below with reference to advantageous embodiments illustrated in the figures. However, the invention is not limited to these embodiments. They show: Fig. 1: schematic representation of a seat arrangement with an adjustment arrangement in side view, Fig. 2: a schematic representation of the seating arrangement in plan view, and Fig. 3: another schematic representation of a seating arrangement in plan view.

[0020] Corresponding parts are provided with the same reference numerals in all figures.

[0021] One in the Fig. A seat arrangement 100 schematically illustrated in Figure 1 for a vehicle, in particular for a rear row of seats in the vehicle, is described below using three spatial directions running perpendicular to one another. In a seat arrangement 100 installed in the vehicle, a longitudinal direction x runs largely horizontally and preferably parallel to a vehicle longitudinal direction that corresponds to the normal direction of travel of the vehicle. A transverse direction y running perpendicular to the longitudinal direction x is likewise oriented horizontally in the vehicle and runs parallel to a vehicle transverse direction. A vertical direction z runs perpendicular to the longitudinal direction x and perpendicular to the transverse direction y. In a seat arrangement 100 installed in the vehicle, the vertical direction z preferably runs parallel to a vehicle vertical axis.

[0022] The position and direction information used, such as front, rear, top, and bottom, refer to a viewing direction of at least one occupant sitting on the seat assembly 100 in a normal seating position, wherein the seat assembly 100 is installed in the vehicle, in a position of use suitable for passenger transport with the backrest 104 upright and oriented in the direction of travel as usual. However, the seat assembly 100 can also be installed or moved in a different orientation, for example, transversely to the direction of travel. Unless otherwise described, the seat assembly 100 is constructed mirror-symmetrically to a plane running perpendicular to the transverse direction y.

[0023] The formed backrest 104 can be pivotably mounted on a seat part 102 of the seat assembly 100. For this purpose, the seat assembly 100 can optionally include a fitting 106, in particular an adjustment fitting, rotary fitting, locking fitting, or wobble fitting.

[0024] The position and direction specifications used, such as radial, axial, and circumferential, refer to a rotational axis 108 of the fitting 106. Radial means perpendicular to the rotational axis 108. Axial means in the direction of or parallel to the rotational axis 108.

[0025] The seat assembly 100 includes an adjustment assembly 110. The adjustment assembly 110 includes, for example, at least one rail assembly 112 with a first rail element 114 as a seat rail and a second rail element 116 as a floor rail. The first rail element 114 is adjustable relative to the second rail element 116 in the longitudinal direction x. The first rail element 114 is attached to the seat part 102. The second rail element 116 is attached to a structural element of a vehicle, for example, a vehicle floor.

[0026] For clarity, the first rail element 114 is referred to as the top rail 114 in the following description. This top rail 114 (also called seat rail, running rail or carriage) is the seat 120 (shown in the Fig. 2 and Fig. 3) and configured to support this seat bench 120. The second rail element 116 is referred to below as the lower rail 116. The lower rail 116 is fixed and connected, for example, to the floor of a vehicle.

[0027] Fig. 2 shows a schematic representation of the seat arrangement 100 in plan view.

[0028] The seat assembly 100 includes a bench seat 120 as the seat part 102. The seat assembly 100 may include one or more separate backrests 104. Alternatively, the seat assembly 100 may include a one-piece bench seat backrest 122.

[0029] The bench 120 can comprise several seating areas 124.1 to 124.3. Preferably, the bench 120 comprises three seating areas 124.1 to 124.3. However, there can also be fewer or more seats.

[0030] The adjustment arrangement 110 is provided for adjusting the seat 120 in the longitudinal direction x.

[0031] The adjustment arrangement 110 comprises a plurality of longitudinal adjustment devices 111, which are, for example, a combination of electric longitudinal adjustment devices 111.1 and at least one manual longitudinal adjustment device 111.2, which are configured and interact with each other to adjust the seat bench 120 in the longitudinal direction x and to lock it in a seating position.

[0032] Fig. 2 shows, by way of example, the adjustment arrangement 110 with two outer electrical longitudinal adjustment devices 111.1 and a single inner manual longitudinal adjustment device 111.2 arranged between these two outer longitudinal adjustment devices 111.1. Fig. 3 shows, by way of example, a further adjustment arrangement 110 with two outer electrical longitudinal adjustment devices 111.1 and two inner manual longitudinal adjustment devices 111.2 arranged between these two outer longitudinal adjustment devices 111.1.

[0033] The functions of the two adjustment arrangements 110 according to Fig. 2 and Fig. 3 do not differ and are described below using an example: The seat bench 120 can be adjusted in the longitudinal direction x by means of the electric longitudinal adjustment devices 111.1. The seat bench 120 can additionally be locked in a seating position by means of the at least one manual longitudinal adjustment device 111.2.

[0034] The seat bench 120, in particular a multiple seat bench, for example a triple seat bench, comprises several longitudinal adjustment devices 111, which are arranged parallel to one another and in contact with one another. In the exemplary embodiment, three longitudinal adjustment devices 111 ( Fig. 2) or four longitudinal adjustment devices 111 ( Fig. 3). However, there may also be more longitudinal adjustment devices 111, for example, five or more longitudinal adjustment devices 111. The core of the invention is the combination of electric longitudinal adjustment devices 111.1 and at least one manual longitudinal adjustment device 111.2.

[0035] The invention is described below by way of example for the adjustment arrangement 110 comprising two electrical longitudinal adjustment devices 111.1 and two manual longitudinal adjustment devices 111.2.

[0036] For example, the adjustment arrangement 110 can comprise the two outer electric longitudinal adjustment devices 111.1 and the two inner manual longitudinal adjustment devices 111.2. For example, for a triple seat bench, the adjustment arrangement 110 can preferably comprise exactly four longitudinal adjustment devices 111, namely two outer electric longitudinal adjustment devices 111.1 and two inner manual longitudinal adjustment devices 111.2. The two inner manual longitudinal adjustment devices 111.2 are arranged between the two outer electric longitudinal adjustment devices 111.1.

[0037] The two outer electrical longitudinal adjustment devices 111.1 are configured, for example, to absorb a lower load than the two inner manual longitudinal adjustment devices 111.2. In particular, the two outer electrical longitudinal adjustment devices 111.1 can be configured to absorb a load in a range of up to a maximum of 60 kN, in particular a longitudinal load of up to 40 kN and / or a peeling load of up to 60 kN. The two inner manual longitudinal adjustment devices 111.2 can be configured to absorb a load in a range of greater than 35 kN up to a maximum of 120 kN, in particular a longitudinal load of up to a maximum of 65 kN and / or a peeling load of up to a maximum of 100 kN.

[0038] The manual longitudinal adjustment devices 111.2 can also be provided with an integrated belt holder 126.

[0039] For example, the manual longitudinal adjustment devices 111.2 can each be provided with a locking device 128 for locking the seat 120 in a seating position in the longitudinal direction x, in particular in an increment over the entire adjustment range of the seat 120 in the longitudinal direction x. The locking device 128 can be designed, for example, as a claw lock.

[0040] The respective longitudinal adjustment device 111 comprises the Fig. 1 described pair of rails with the lower rail 116 and the upper rail 114, which are displaceable relative to each other in the longitudinal adjustment direction in the longitudinal direction x.

[0041] The electrical longitudinal adjustment devices 111.1 can, for example, have a spindle drive (not shown in detail) for electrical longitudinal adjustment.

[0042] During a longitudinal adjustment, the locking devices 128 of the manual longitudinal adjustment devices 111.2 are unlocked, for example, via actuators. Alternatively, these locking devices 128 can also be unlocked manually. Subsequently, the seat bench 120 is adjusted to the longitudinal position in the longitudinal direction x using the two electric longitudinal adjustment devices 111.1.

[0043] In particular, the electric longitudinal adjustment devices 111.1 and the manual longitudinal adjustment devices 111.2 are motion-coupled via the seat bench 120. For example, the electric longitudinal adjustment devices 111.1 and the manual longitudinal adjustment devices 111.2 are motion-coupled to one another such that when the electric longitudinal adjustment devices 111.1, in particular their upper rails 114 (also called seat rails), are actuated and adjusted in the longitudinal direction x, the manual longitudinal adjustment devices 111.2 are automatically actuated (co-actuated) and adjusted (co-adjusted) in the longitudinal direction x, in particular their movable upper rails 114 are moved along.

[0044] At the end of the longitudinal adjustment, the actuators bring the locking devices 128 of the manual longitudinal adjustment devices 111.2 back into the lockable position, wherein the seat bench 120 continues to be adjusted by the electric longitudinal adjustment devices 111.1 until the manual longitudinal adjustment devices 111.2 engage or fall into the next locking window or locking slot of the locking devices 128 and the manual longitudinal adjustment devices 111.2 and thus the seat bench 120 are locked.

[0045] The locking of the manual longitudinal adjustment devices 111.2 can optionally be monitored, for example, by means of monitoring units, such as at least one microswitch.

[0046] The seat bench 120 comprises four longitudinal adjustment devices 111, which are fixedly mounted at equal intervals to the seat bench 120 on the one hand and to a floor (not shown) on the other. The movable upper rail 114 of the respective longitudinal adjustment device 111 is attached to the seat bench 120. The stationary lower rail 116 is attached to a vehicle floor or embedded in it.

[0047] When attaching a seat bench 120 designed as a triple seat bench to four longitudinal adjustment devices 111, tension may occur due to tolerances.

[0048] For example, some of the longitudinal adjustment devices 111 are not rigidly coupled to one another via the seat bench 120.

[0049] To reduce such tension, a flexible decoupling, in particular rubber elements or the like, can be provided, for example, between the electric longitudinal adjustment devices 111.1, in particular their upper rails 114, and the seat bench 120 (also called the seat structure). The seat bench 120 can then, for example, be firmly connected only to the manual longitudinal adjustment devices 111.2, in particular their upper rails 114.

[0050] Alternatively, the seat bench 120 can also be firmly connected to the electric longitudinal adjustment devices 111.1, in particular their upper rails 114, and flexibly connected to the manual longitudinal adjustment devices 111.2, in particular their upper rails 114.

[0051] By such a partial flexible decoupling of the seat 120 from at least one or more of the longitudinal adjustment devices 111, tensions can be avoided.
