Description

(57)

In a couchette-shaped furniture seat equipped with a retractable trolley (2) that can be moved out of the seat base (1), an additional cushion (5), which can be raised and lowered, the seating position of the seat is submerged under the seat cushion (4), while in the couchette adjustment of the seat it is connected to the seat cushion (4), the forging (6) being a longitudinal (7) connected to the extendable carriage (2) and with additional cushion (5) and two rocker arms (9, 10). In order to arrest the additional cushion (5) in an upward-facing position, a crossmember (11) is rotatably mounted on the rocker arm (10), which bears against a pin (14) mounted on the carriage (2) and has a recess (12). with which the pin (14) can engage as well as a pivotably mounted guide (15) which can guide the pin (14) through the recess (12).

Technical field

BACKGROUND OF THE INVENTION 1. Field of the Invention The invention relates to a furniture seat with a couchette arrangement, which is provided with an extendable carriage arranged in the base of the seat.

BACKGROUND OF THE INVENTION

In similar known seats, the carriage is pulled out when changing to a couchette and raising the additional cushion to the level of the seat cushion. In this raised position, the cushion, with its front part, rests on the front face of the carriage, while its rear part is held by the four-hinged fitting in the raised position. In the known seats, the space under the additional cushion cannot be used to accommodate the bedding, since there is no device to hold the additional cushion in an angled upward position, which would then allow access to this space. Although there are fittings which are provided with a tension spring ensuring the desired position, however, due to the different weight of the loading part, the use of tension springs is problematic because the force required for them is also different.

SUMMARY OF THE INVENTION

SUMMARY OF THE INVENTION It is an object of the invention to provide a fitting which fulfills the above-mentioned function of raising the additional cushion and at the same time ensuring a secure locking of the additional cushion in an upward-facing position.

In the case of a chair-shaped furniture seat characterized by the introduction, this function is achieved by rotatably mounting a cross member to the rocker, which rocker bears on a pin located on the trolley and yet has a recess in which the pin can engage and a rotary guide allowing relative movement the spigot and shoulders without the spigot fit into the recess.

In the seat according to the invention, the pin engages in the recess of the arm after raising the auxiliary cushion at an selectable intermediate position when the auxiliary cushion is directed obliquely upward, thereby locking the auxiliary cushion. This now allows free access to the space under the auxiliary pillow. When lifting, respectively. The deflection of the additional cushion slips the pin by means of a guide from the recess and, in retraction, the pin then passes over the guide which in the meantime has been placed over the recess of the arm, so that the additional cushion can be extended or retracted. In principle, the bolt could be mounted on the trolley independently of the four-hinge fitting, but for ease of assembly, it is preferred within the scope of the invention for the bolt to be located on the fitting cross member.

A suitably selected arrangement is further characterized in that the arm is located on a longer rocker arm.

Overview of the drawings

In the following, the invention is described on the basis of an exemplary embodiment shown in the drawings. Giant. Fig. 1 shows the seat according to the invention in the seating position; Fig. 2 shows the front part of the seat in the position where the additional cushion faces obliquely upwards and thus allows access to the space under the additional cushion; to Fig. 8 different positions of the arm and the pin, the position according to Fig. 4 corresponding approximately to the seating position of the seat (Fig. 1);

FIG. 5 shows the elevated position according to FIG. 2 and the position in FIG. 8 approximately the couchette position of the seat (FIG. 3).

DETAILED DESCRIPTION OF THE INVENTION

According to the drawings, a carriage 2 with rollers 3 is arranged in the seat base 1 so that it can be retracted and retracted. A seat cushion 4 is supported on the base 1 of the seat. In the carriage 2, an additional cushion 5 is arranged so that it is raised and lowered, forming together with the seat cushion 4 and, if necessary, the seat cushion 4. with another cushion (not shown) the bed surface. The support of the additional cushion 5 is provided by two four-articulated fittings 6 located on the sides of the additional cushion 5. Both fittings 6 are mirror images of each other, so that only the function of one of them is described below.

The fitting 6 is formed to the carriage 2 by means of a bolted longitudinal 7 with an inclined arm T, to which the rocker arms 9 and 10 are rotatably mounted. Also, the rocker arm 10 has an inclined arm 10 '. The two rocker arms 9, 10 are rotatably connected by a connecting rod 8 which is screwed to the seat cushion 4.

A beam 11 is rotatably connected to the rocker arm 10, which is provided with a recess 12. A plate B, which is provided with a pin 14, is riveted with the longitudinal 7, so that the pivot bar 11 fits on the pin 14. 11, a pivot guide 15 closing the recess 12 is connected so that the recess 12 of the crossbeam 11 can pass over the pin 14. Referring to FIGS.

If, after pulling the carriage 2, the additional cushion 5 is lifted out of the position shown in FIG. 1, the crossbar 11 travels over the pin 14 so that, according to FIG. When the recess 12 of FIG. 5, the pin 14 engages the recess 12. In this position, the crossbar 11 thus holds the additional cushion 5 in the position of FIG. 2, which allows access to the bedding compartment.

If the additional cushion 5 is pulled further upwards, the crossbar 11 travels further over the pin 14 by the guide 15 (FIG. 6). After passing the guide 15, the additional cushion 5 and hence the cross member 11 can be moved back, the pin 14 pivoting the guide 15 so that the recess 12 is closed and the additional cushion 5 can be placed in the position shown in Fig. 3 (Figs. 8).

When the seating position shown in FIG. 1 is converted to the couchette position shown in FIG. 3, the rocker arms 9 and 10 naturally move accordingly.
