DE102005025544A1 - Seating device e.g. for motor vehicle, has second row of vehicle seating arranged behind first, which is suitable as supporting surface for legs of passenger present at second vehicle seating - Google Patents

Abstract

The seat (1) has a first row of vehicle seating (3) and a second row of vehicle seating (4), arranged behind the first. The seats have a backrest (7, 8). The first vehicle seating is suitable as a supporting surface for the legs of a passenger present at the rear vehicle seating. The backrest of the front vehicle seating can move from a custom position into a supporting position by means of a hinge. The legs are also supported by pads (10) which can be moved into a gap (12) between the backrest of the front vehicle seating (3) and the rear vehicle seating. An independent claim is included for a vehicle.

Description

The The invention relates to a seat system for vehicles, in particular for motor vehicles, with a first vehicle seat and a second arranged behind it Vehicle seat, each a seat part and a backrest , wherein the first vehicle seat is suitable, a support surface for the legs of an occupant located on the rear seat of the vehicle, as well as a vehicle equipped with it.

State of technology

A generic seat system is known from practice. It consists of a front vehicle seat, which is arranged next to the driver is, and one far behind the first vehicle seat rear seat. The backrest of the front vehicle seat is equipped with an opening at Use of the front seat by a pivoting segment of the backrest is closed. After folding back of the segment ("footboard") from the still upright backrest can the legs extending through the resulting opening a rear passenger on the A side of the segment. The inmate stands thus in addition to the normal sitting position, in which the legs angled are and feet on the Vehicle floor rest, a comfort position available, in which the legs are stretched in a substantially horizontal orientation are. A frame part of the backrest however, remains in an upright position so that the comfort position in terms of an increase in the loading capacity the vehicle offers no advantages. There is also a risk the seat cover of the front vehicle through the shoes of the rear Pollute occupants.

Of the Invention is based on the object, the previously known seat system in terms of comfort and variability.

solution

The The object is achieved in that the backrest of the front vehicle seat from its position of use to the front the seat part in a support position is hinged and at least one legs also supporting separate Upholstered part in the gap between the backrest the front vehicle seat and the seat part of the rear vehicle seat is relocatable.

Of the Expression "after front "is in usual seating arrangements in the sense of "in Direction of travel ".

The supporting position the backrest is therefore suitable, not only a comfort position, but also a long loading area to train in the vehicle. The backside the backrest is complete as support surface for the Legs of the rear seat occupant available. The term "legs" includes any Parts of the lower extremities seat occupants, including his feet.

A passing The legs are thereby avoided that a separate, so not to the usual upholstered areas of front or rear vehicle seat belonging cushion part into the gap between the folded forward backrest and the seat part the rear vehicle seat is displaced and the legs in particular is supported in the region of the knee and / or calf.

To a first preferred embodiment of Invention is the upholstered part of the folded forward backrest the front vehicle seat displaced to the rear. With advantage is the cushion part at the lower end of the back of the backrest rotatably mounted and from its storage position, in which the upholstery at the back the backrest abuts, from the folded forward backrest at an angle of about 180 ° to the rear in a support position pivotable. Alternatively, the cushion part slidably on the Back of the backrest can be arranged and is from the folded forward backrest back to his support position displaceable.

To Another advantageous embodiment of the invention is the cushion part from his in the area of the seat part of the rear vehicle seat located stowage position forward to its support position displaced. The Upholstery is articulated in particular in the front region of the seat part stored and from a preferably vertical storage position after in the front in its supporting position pivotable, wherein the articulated mounting a multi-link mechanism, in particular a four-bar linkage or a scissor mechanism. Further is conceivable, the upholstery part below the seat part of the rear Vehicle seat slidably store and forward in its support position displaceable form.

It is natural conceivable, the gap between the first and second vehicle seat also by several upholstery parts close, for example, by combining the previously described training.

characters

The Figures represent examples and schematically different versions of the invention.

It demonstrate:

1 a seat system in a motor vehicle according to a first embodiment of the invention in normal and comfort position,

2 to 5 another seat according to the invention in the relevant positions.

In the 1 illustrated seat system 1 of a motor vehicle 2 includes passenger side, a front first vehicle seat 3 and a second, rectified rear vehicle seat 4 , each a seat part 5 . 6 and a backrest 7 . 8th exhibit. At least the backrest 7 of the front vehicle seat 3 is articulated with the associated seat part 5 connected. In the presentation after 1a is the first vehicle seat 3 in its position of use, the backrest 7 of the front vehicle seat 3 is aligned in an upright position.

After folding the backrest 7 in a substantially horizontal support position ( 1b ) is one on the rear vehicle seat 4 seat occupants an extended seat available, with the feet on the back 9 the backrest 7 rest.

At the bottom of the backrest 7 is a separate flat upholstered part 10 by means of a joint 11 pivotally mounted about a horizontal, transverse to the sitting direction axis of rotation. In use position of the front vehicle seat 3 lies the cushion part 10 at the back 9 the upright backrest 7 on (stowed position after 1a ), after folding the backrest 7 but at an angle of about 180 ° backwards into the gap 12 between the vehicle seats 3 . 4 be pivoted (support position to 1b ). In this position, the legs of the rear seat occupant can in particular in the knee or calf area on the support side 13 of the upholstery body 10 rest, which in stowed position at the back 9 the backrest 7 is applied.

In the execution after 2 is the upholstery element 10 not rotatable, but in a rail 14 parallel to the back 9 slidable on the backrest 7 arranged and can with folded down backrest ( 2a ) back into the gap 12 be moved.

The car 1 to 3 is with a cushion part 10 equipped, which in the area of the rear vehicle seat 4 one at the front edge 15 of the relevant seat part 6 arranged simple joint 16 is rotatably mounted. The upholstery part is out of its stowed position, in which it from the joint 16 protrudes downwards ( 3a ) by 90 ° upwards into its substantially horizontal support position ( 3b ) pivotable and fixable in this position. The support side 13 is visible both in stowed position and in support position from the vehicle interior ago.

In the execution after 4 is the upholstery part 10 about a four-joint (joints 17.1 to 17.4 ) opposite the seat part 6 swiveling, with the joints 17.1 and 17.2 the seat part 6 and the joints 17.3 and 17.4 the upholstery part 10 assigned. Two articulated arms 18.1 . 18.2 connect the joint 17.1 with joint 17.4 or the joint 17.2 with joint 17.3 ,

By overstretching the four-bar linkage, a stable positioning of the upholstery part can be achieved 10 in its support position ( 4b ) be achieved.

5 represents a seat system in which the upholstered part 10 by means of a scissors mechanism 23 relative to the seat part 6 is pivotable. The scissor mechanism 23 consists in the embodiment of two spaced-apart seat part side joints 19.1 and 19.2 , two spaced-apart cushion part side joints 19.3 and 19.4 , as well as three other joints 19.5 to 19.7 which the articulated arms 20.1 to 20.4 of scissors mechanism 23 connect with each other. By stretching the scissors mechanism 23 from the stowage position ( 5a ) into the support position ( 5b ) becomes the upholstery part 10 moved to both forward and upward. A gas spring 21 holds the upholstery part 10 in its supporting position.

The seat part side joints 19.1 and 19.2 are on a bracket 22 arranged, which is also the free end of the piston of the gas spring 21 receives. cushion body 10 , Scissor mechanism 23 , Bracket 22 as well as gas spring 21 thus form a self-sufficient unit with which the seat 1 can be retrofitted at any time.
