Description

Technical area

The invention relates to seat adjustment systems for motor vehicles, in particular for the individual configuration of seat components of vehicle seats in a motor vehicle.

Technical background

Seating systems in means of transport, such as motor vehicles, usually have a classic arrangement of vehicle seats oriented towards the front, which can be designed as front seats arranged next to each other and as rear seats integrated next to each other in a rear seat. The vehicle seats can usually be moved in the front direction as a whole. Furthermore, individual seat components are adjustable, such as the seat height and the backrest inclination.

The rigid arrangement of the rear seats in particular hinders passenger interaction, and it is therefore desirable to enable a more flexible arrangement of vehicle seats, in particular in the rear area of the vehicle. To this end, in some motor vehicle models, in particular in so-called vans, provision can be made for vehicle seats to be installed facing each other as required, so that passengers can sit opposite each other, with one of the vehicle seats facing the front and one of the vehicle seats facing the rear. Converting vehicle seats to such a configuration is usually complex and requires lifting out the vehicle seat in order to move it to a different position or to remove it from the vehicle.

The publication DE 198 16 031 A1 discloses a floor assembly of a passenger car with longitudinal floor members and floor panels mounted between them. Three longitudinal floor members are provided, which are designed as straight floor rails running approximately parallel to the longitudinal direction of the vehicle, two of which are designed as side rails and one as a center rail. The floor rails are connected to floor panels in a lower area, so that an elongated left floor pan is formed in connection with the left side rail and the center rail, and an elongated right floor pan is formed in connection with the right side rail and the center rail.

The publication DE 699 20 043 T2 discloses a seat arrangement for a motor vehicle having a number of seats which are slidable between various mutual positions along at least two parallel rails in the longitudinal direction of the motor vehicle in the motor vehicle floor, the seats being slidably attached to the rails by means of connecting members by means of which the seats are lockable in a plurality of positions along the rails; a seat portion of the seats being pivotally mounted with respect to a backrest portion in such a way that it can assume a first folded-down position and a second position in which it is folded against the backrest portion; at least one rail extending in the transverse direction of the motor vehicle, the transverse rail interconnecting the rails longitudinally such that the seats can be moved via the transverse rail from engagement with one longitudinally extending rail into engagement with the other.

The publication DE 699 29 726 T2 discloses a vehicle seating assembly comprising a substantially flat floor surface, seats, a seat storage pan extending rearwardly from a rear row seat and downwardly from the plane of the floor surface, a substantially flat and uninterrupted surface on substantially the same plane as the floor surface formed rearwardly from the middle row seats to the end of the vehicle interior and having substantially the full width of the vehicle interior when the rear row seat is received in the seat storage pan. The rear row seat is provided with a seat cushion, a seat back and a hinge disposed at the rear of the rear row seat, wherein when the rear row seat is tilted rearwardly about the hinge while maintaining a normal sitting posture.

It is an object of the present invention to provide a seating system for a means of transport in which the arrangement and configuration of the vehicle seats can be changed in a particularly simple manner and with increased degrees of freedom.

Short description of the drawings

• 1 eine schematische Darstellung eines Ausschnitts aus einem Sitzsystem mit entlang von Führungsschienen verstellbaren Sitzkomponenten; und
• 2 eine mögliche Form einer Schienenanordnung für ein Sitzsystem in einem Kraftfahrzeug.

Embodiments are explained in more detail below with reference to the attached drawings. They show:

• 1 a schematic representation of a section of a seating system with seat components adjustable along guide rails; and
• 2 a possible form of a rail arrangement for a seating system in a motor vehicle.

Description of embodiments

1 shows a section of a seat system 1 with a laterally displaceable vehicle seat 2. The vehicle seat 2 is formed from seat components 21, each of which can be displaced separately in the lateral direction Q (transverse to a seat direction S) along a guide arrangement 3 with guide rails 31 assigned to the seat components 21. The seat direction S corresponds to the direction in which the seat components 21 are to be arranged in order to form the vehicle seat 2.

The guide arrangement 3 is essentially formed with a flat surface so that the guide rails 31 are recessed into guide openings.

The seat components 21 can comprise, for example, a headrest 21a, a neckrest 21b, a backrest 21c, a belt holder 21d and a seat surface 21e. The seat components 21 can also be provided merely as support structures in order to attach cushions or upholstery thereto using suitable connecting devices. The connecting device can comprise, for example, Velcro connections, click connections, snap fastener connections, magnetic connections or the like.

Each of the seat components 21 has one or more guide elements 23, each of which is accommodated in a corresponding guide rail 31. The seat components 21 are thus movable along the extent of the guide rail 31, i.e. in the transverse direction Q, so that different seat components 21 can be aligned with one another and thus combined with one another to form a vehicle seat. The seat components 21 are held in the guide rails 31 in a form-fitting manner to prevent them from falling out. For this purpose, the guide elements can be provided with a roller system (not shown) to enable low-friction sliding along the guide rails 31.

The seat components can be locked in position by a suitable locking device 22. The locking device 22 can engage in a holding element on or in the respective guide rail 31 and thus reliably hold the seat component against lateral displacement.

The guide rails 31 can be open at least at one end E, so that the seat components 21 can be removed by moving them to the open end of the guide rails 31. The removed seat component 21 can then be replaced by another seat component 21 with a different alternative shape. For example, neck supports 21b as seat component 21 can have different thicknesses and can thus be individually adjusted according to the comfort requirements of a passenger.

In 2 an example of a guide arrangement 3 is shown in a top view of a motor vehicle 5. The guide arrangement 3 can be arranged on a base structure 4, which can be part of a body 51 of the motor vehicle 5. The base structure 4 specifies the seat contour on which the seat components are aligned and can basically be designed to be straight or curved, with the guide rails 31 essentially parallel to one another following the course of the base structure 4.

In the example of 2 the guide arrangement 3 has guide rails 31 which extend along a substantially U-shaped base structure 4. This substantially U-shaped base structure 4 makes it possible to arrange two vehicle seats 2 next to one another and, in particular, to arrange them aligned in the front direction during driving, and by moving the seat components 21 to the legs of the U-shaped base structure 4, the vehicle seats 2 can also be arranged facing one another, as shown in 2 is shown.

The construction of the vehicle seats 2 using seat components 21 enables the individual configuration of each vehicle seat 2 and makes installation and removal easier, since the seat components 21 have a significantly lower weight than an entire vehicle seat. The storage of the seat components 21, when they are not installed in a vehicle, is also possible in a more compact manner.
