The invention relates to an articulated fitting for vehicle seats with swiveling backrest and at least one swiveling armrest.

The invention 2 is based on the object to create a hinge fitting of this type, which with a minimum of material and assembly effort can be produced.

According to the invention, this task is in a hinge fitting of the type mentioned above achieved in that the holder for the armrest is to be attached to the seat part of the vehicle Part of the hinge fitting is combined into a single unit.

The invention is explained in detail below with reference to the drawing.

1 and 2 show an embodiment of the hinge fitting for a vehicle seat with a pivoting backrest 1 without an additional adjustment mechanism for the optional adjustment of the inclination of the backrest 1. The vehicle seat has a seat part 2 and an armrest 3 in addition to the backrest. The armrest 3 is pivotably mounted in a cold designated as a whole with 4, so that the armrest 3 can be moved between a substantially horizontal position of use, which is shown in FIGS. 1 to 4, and a folded-up position in which the armrest can be moved 3 extends substantially in the direction of the backrest 1 upwards. The holder for the backrest is designed as an upwardly extending and upwardly open fork made of two spaced apart cheeks 5 and 6, which are firmly connected to each other, for example welded, with an angle piece 7 being welded in the embodiment for reinforcement. With its lower end, the cheek 5 of the holder 4 closest to the backrest 1 and the seat part 2 simultaneously forms the part of the hinge fitting to be attached to the seat part 2, to which the backrest 1 is hinged by means of a hinge pin 8 for folding it down. The hinge pin 8 extends through a bore formed in an extension 9 of the cheek 5. The extension 9 extends from the lower part of the cheek 5 upwards and backwards. The hinge pin 8 passes through a hinge plate 10 serving to hold the backrest 1 thereof.

As can be seen, the holder 4 of the armrest 3 thus forms a structural unit with the part of the hinge fitting attached to the seat part, to that in the embodiment according to FIGS. 1 and 2 except the cheek 5 with the extension 9 nor the Hinge pin 8 and the hinge plate IO belong.

For the pivotable mounting of the armrest 3 in the holder 4, a bolt 11 is provided which the upper ends of the tlureb the

Cheeks 5 and 6 formed fork connects. With the armrest 3, a detent segment 12 is connected to rotate, the two notches and 18 for the engagement, a pawl 13 has on a safety lever 14 which is pivotable on a pin 15 in the holder 4 is mounted and is biased by means of a wound around the pin 15 spring 16 so that the pawl 13 in the Notices 17 and 18 of the notch segment 12 seeks to collapse. The spring 16 is supported on the one hand on the safety lever 14 and on the other hand at the elbow 7.

In the folded up position, the armrest 3 is secured by engagement of the pawl 13 in the catch 18. In the In the horizontal position of use, the armrest 13 is not only secured by the engagement of the pawl 13 in the catch 17, but the armrest 3 also lies on a contact surface which is formed by the top of a tab 19 which is inserted into a recess in the inner cheek 5 that forms a step it.t welded into the interior through the cheeks 5 and 6 formed fork extends into it. By resting the armrest 3 on the contact surface of the flap 19, it is prevented that even under high loads, for example if a person accidentally sits on the armrest 3, this in the event of a possible Unlatching the pawl 13 from the catch 17 could be pivoted downward beyond the position of use.

3 and 4 show an embodiment that differs from first embodiment differs only insofar as an adjusting mechanism is additionally provided, which an optional change in the angle of inclination of the adjustable Backrest 1 allows. Parts that correspond to those of the previous exemplary embodiment are given the same reference numerals so that these parts do not have to be described again. In this embodiment is the holder 4 formed from the cheeks 5 and 6 with ainer the Port set 9 of Figs. 1 and 2 corresponding plate

on which the adjustment mechanism for the inclination of the pivotable backrest is attached to form a rigid structural unit united. This adjusting mechanism is of the usual type ;; ind has an actuating element 120.

In the case of the joint fitting shown here, as from the above it can be seen, the holder 4 and the to be attached to the seat part 2 Part of the hinge fitting combined into one structural unit. This has the advantage of being simplified Assembly. The assembly can be carried out after the individual parts have been upholstered. Since the holder for the Armlciüine with the part of the hinge fitting to be attached to the seat part is summarized for the pivoting backrest, the articulation point for the armrest 3 is more favorable Weis "relatively far back, so that the armrest is relatively far out of the seating area as desired after it has been folded up is moved out. The formation of the holder 4 as a GabsjL from the cheeks 5 and 6 results in the distribution that the locking mechanism the armrest 3 can be safely housed inside the fork and through the articulated above Armleltine is covered at the top.
