Description

The The invention relates to a motor vehicle seat with an integrated Child seat with the features mentioned in the preamble of claim 1.

From the prior art vehicle seats are generally known, which are provided from a continuous cushion body seat cushion with lateral Randwülsten to provide the user with a lateral support. From the DE 15 80 621 For example, a seat protrudes with a resting on a frame, lateral supports having seat cushion. The seat cushion is subdivided into three juxtaposed individual parts, of which the middle part on the frame, the two seat parts are arranged on each one fixed to the frame hinged side support whose pivot axes are substantially parallel to the upper side edges of the middle part.

A similar solution knows the DE 43 05 295 A1 , Which discloses a arranged next to a vehicle side wall seat, which has at least one sidewall side from a rest position releasing the vehicle occupant laterally on the seat in a side cheek movable laterally supporting him operating position.

on the other hand is with regard to child seats integrated in vehicle seats Known to design the vehicle seats so that you can transform from an adult seat with normal seat height and seat in one Child seat with an elevated and reduced seating area and vice versa. The production of an elevated seat For example, with a mechanical adjustable support device for the Child seat realized. The set height of the seat becomes each secured by a locking of the support device.

From the prior art a variety of solutions are known, the DE 17 803 A1 For example, describes a passenger seat with integrated child seat having a backrest, a backrest support and a backrest cushion. The seat back cushion includes two side cushions and an intermediate backrest center pad which includes a first, lower and in use of the child seat, the backrest cushion for the child seat cushion body and a second, when not using the child seat on the first cushion body to form the backrest surface of the passenger seat around a Having in the lower region of the backrest extending axis of rotation of the first cushion body to the front unfolded, the seat cushion of the child seat forming cushion body.

For the formation of the seat cushion or the seat, for a child using the vehicle seat show the documents FR 0286542 or the DE 19537169A1 also integrated solutions. The FR 0286542 allows by a mechanical lever device swiveling the seat cushion from the normal sitting position to an elevated child seat position. The DE 195 37 169 A1 discloses another solution for converting the vehicle seat into the child seat, wherein a child seat element is moved out of a backrest or a seat cushion part. In connection with the generally customary trained vehicle seats with appropriate possibilities to form a lateral support, also raises the question of the necessary lateral support in integrated child seats.

Of the Invention is based on the object an integrated child seat to create, as usual for motor vehicle seats a additional Provides lateral support.

The Task is solved by that a child seat seat part and / or a child seat backrest at least one adjustable Side cheek having its pivot axis substantially parallel to the respective side edges of the child seat seat part and / or the Child seat backrest is arranged, wherein the at least one adjustable side cheek from one together with the child seat seat part and / or the child seat backrest one essentially flat seat and / or forming backrest surface Basic position in at least one position of use for generating a Side stop of the child seat can be brought.

In a preferred embodiment of the invention, therefore, the at least one side cheek in the basic position is part of the substantially flat seat surface of the seat part and / or the substantially flat backrest surface of the backrest. A first use position receives the integrated child seat in that, while maintaining the basic position of the child seat seat part and / or the child seat backrest only by shifting at least one side wall of the respective surfaces out, so the substantially flat seat and / or flat backrest surface, a Seitenhalt is formed. For this purpose, for example, the child seat seat part and the child seat backrest on each side cheeks along the respective side edges, which can be brought with and without displacement of the child seat seat part and / or the child seat backrest in an open position, so that already here a child seat with pretended Side cheeks and necessary lateral support in the first position of use can be formed.

A preferred second use position of the integrated child seat is ausbildbar by the child seat seat part and / or the child seat backrest together with the arranged side cheeks from the basic position is shifted out and locks in a second position of use and is locked. This locking and unlocking is done by a Actuator according to the invention, which preferably in the front of the child seat seat part or with respect to Child seat backrest is arranged for example in the front region of the child seat backrest. In This raised child seat seat part position or the shifted in and against the direction of travel child seat backrest position are then each along the side edges of the child seat seat part and / or the child seat backrest arranged side cheeks in the final second use position adjustable or already as already described a lateral support bidding from the basic position to the first position of use Service.

The arranged side cheeks are in a preferred embodiment of the invention reversible to create the lateral support in any desired position lockable, preferably lockable.

Further preferred embodiments of the invention will become apparent from the others, in the subclaims mentioned features.

The Invention will be described below in an embodiment with reference to the accompanying drawings explained in more detail. It demonstrate:

1 a front perspective view in a training stage of the integrated child seat before taking a second use position (B) of a child seat seat part;

2 a front perspective view of a second use position (B) of the child seat seat part of the integrated child seat and

3 an enlargement of a side cheek on the child seat seat part of the integrated child seat in the second use position (B), according to 2 ,

The 2 and 3 each show the same reference numerals for the same components in one embodiment, a motor vehicle seat 10 with a child seat already in a second position B use 12 , but in which only a child seat-seat part 20 in the second use position B has been transferred.

The 1 shows a precursor "before B" in the formation of the second use position B. The invention is not on this embodiment with respect to the second use position B of the child seat seat part 20 limited; but also concerns the adjustment of the child seat backrest 22 and accordingly, since the adjustment of the child seat backrest 22 not shown is described in parallel without reference numerals.

The integrated child seat 12 is integrated in a basic position in a seat part 14 and a backrest 16 (not shown) arranged. The child seat seat part 20 and a child seat backrest 22 form in the basic position of the integrated child seat 12 a part of the substantially flat seat surface of the seat part 14 or a part of the substantially backrest surface of the backrest 16 out. Starting from this basic position, not shown, shows the embodiment 1 one out of the seat part 14 moved child seat seat part 20 with a movably arranged first and second side cheek 24 . 26 , which previously in a depression 28 of the seat part 14 was arranged.

This first and second side cheek 24 . 26 forms in the basic position, so the arrangement in the example child seat-seat part 20 and associated side walls 24 . 26 still in the depression 28 are arranged substantially flat, together with the actual seat part 14 the seat of the vehicle seat 10 out.

Analog can also (not shown) one from the backrest 16 in and against the direction of travel movable child seat backrest 22 be arranged, which also each have a side cheek along the side edges of the child seat backrest 22 that protrudes from the backrest 16 is encompassed in the basic position and in the basic position together with the backrest 16 forms a substantially flat backrest surface.

1 already shows the side cheeks in the perspective view 24 . 26 on the child seat seat part 20 in a not yet arranged about pivot axes SA pivoted Ausstellposition before the second use position (before B).

The Ausstellposition the illustrated first and / or second side cheek 24 . 26 or analog side bolsters (not shown) on the child seat backrest 22 is possible both from the basic position to a first use position A, as well as, as here in 2 and 3 shown in the second use position B possible.

The second use position B lies in 2 and 3 before, when the child seat seat part 20 and / or the child seat backrest 22 is moved out of the basic position and at the same time at least one side cheek on the child seat seat part 20 , so here the first and / or second side cheek 24 . 26 or on the child seat backrest 22 at least one (not shown) side cheek is transferred to the open position.

The first use position A (not shown) results when the child seat seat part 20 and / or the child seat backrest 22 in the planar arrangement of the seat part 14 and / or the backrest 16 remains and only at least the first and / or second side cheek 24 . 26 or the unillustrated side cheeks of the child seat backrest 22 is brought in a Ausstellposition.

Of course, the child seat 12 as already described, both from the basic position directly into the second use position B or from the basic position to the first use position A and then by lifting the child seat seat part 20 and / or the displacement of the child seat backrest 22 in the direction of travel in the second use position B can be transferred.

As an actuator 30 to achieve the second position of use, ie for release, for example, for the child seat seat part 20 as in the 1 to 3 shown, serves a button that unlocks the child seat seat part 20 in the basic position is pressed by pressing, so that the child seat seat part 20 can be raised and locked again and after adjustment at least one Seitewange 24 . 26 , according to 2 and 3 the second use position B is set.

A reversible unlocking is done by pulling the actuator 30 and unlocking the child seat seat part 20 and shift down and locking in first use position A - with still adjusted side cheeks 24 . 26 or the basic position with flat side cheeks 24 . 26 based on the surface of the seat part 14 ,

An analogous embodiment relates to the child seat backrest 22 for shifting from the backrest 16 out also an actuating element (not shown), so that a reversible displacement in and against the direction of travel with subsequent adjustment of at least one side cheek is possible.

In any case, results in the first basic position A is already a side support for children in the child seat seat part 20 and / or the child seat backrest 22 not yet moved out of the planar arrangement of the seat part and / or the backrest. Such an arrangement may be appropriate for larger toddlers who no longer need to sit elevated. The second use position B also gives a child a better favorable lateral support with elevated child seat seat part 20 and optionally displaced child seat backrest 22 especially at high cornering speeds or in the event of a side crash.
