Description

"Verstellseasel"

The invention relates to a: * adjustable leash with changeable ί-It »incline and adjustable sitting angle.

In known designs migrate when adjusting the armchair from the itzstellung in a .teil with a larger nits angle with equilateral inclination of the seat backwards, der:. '. it »and thus the center of gravity of the armchair also to the rear, so that well-known adjustable sea donkey, among other things, a relatively large Have depth so that you cannot tilt backwards when the seat angle is increased. In addition, is in known reclining armchairs the use of loose, so-called HammerkopfKiseen, as Sitskisnen with hammer-head-like approaches the front gripping the sesael armrests, which makes little sense, because when adjusting the Gitzwinkela the ■ itz is always relative to the loose Hammer head pillow is moved.

The object of the invention is to create an adjustable armchair of the type described at the outset, which is shorter in depth can be measured as a known Verstellseesel without the risk of overturning to the rear. But also the The use of so-called hammer-head seat cushions, possibly also firmly connected to the seat, allows. The solution to this problem is characterized according to the invention in that both sides of the armchair seat and the armchair

backa A multi-link chain in each case suspended in a stable manner iat, each of the link chains consists of two articulated on the frame There is a swing aimed at the bottom, which is caused by a Couplings are connected to oiner four-bar chain, with the posterior wing of the fieeselback is attached, and dieae The swing arm also has a lever that pushes forward, also at the paddock two more, but aiming upwards

Swing hinged Bind, which are coupled with the seat and a control element that can be influenced by the rocker arm engages on the rear rocker arm acting on the itz.

These measures are used when increasing or decreasing the Seat angle with simultaneous change of position of the seat the backward movement or forward movement of the seat by the in each case opposite movement of the coupling from which the strive for the fitz-supporting wings, compensated so that now there is no change in the position of the front edge of the seat in relation to the armchair frame.

Furthermore, the invention is characterized in that the vorbeechritten Gecenetand the opposing links of the four-link chain, the swing of which is on the one hand on the armchair frame are articulated, are approximately the same length, furthermore the front · rocker on a downward bracing arm of the Coupling is articulated and the front Gede11schwingen articulation point are arranged approximately at the height of the seat. This has the advantage that there are no links in the adjusting mechanism protrude over the armchair seat.

Furthermore, an advantageous and inventive design of the above-described subject is characterized in that the hinge points of the hinged on the coupling are characterized by wings aiming at the top, opposite the hinge points of the am Frame hinged υ id to the paddock attacking wings are arranged offset in front, and preferably also the hinged to the coupling, upwardly aiming wings shorter than the are hinged to the frame, pointing downwards.

To change the seat inclination, an advantageous and inventive feature of the above-described subject is characterized in that the upward-aiming, The front rocker arm is shorter than the rear, upwardly aiming rocker arm, which is hinged to the paddock, and preferably also the At the back of the head hinged, upward-pointing swing arm to the left is arranged inclined at the rear.

An advantageous and inventive development of the above-described subject, which is a further enlargement of the Seat angle and even a greater inclination of the seat than before, is characterized in that to control the of The link arm struts upwards, the seat-supporting swing arm can be influenced by the swing arm lever strut forwards Cam drives are arranged.

To this end, a preferred and inventive embodiment is characterized in that, in the case of the above-described subject, the rear * The rocker that supports the hive seat ends in a fork near the lower hinge point, into which one on the lever of the rear rocker g -

lagarte Holle engages, and the rocker also has, following the fork, a curve that continues upwards and corresponds to the roller _ ύί- "en jjL-iluiniuzi ^ srediiis von de? Fork off.

Embodiments of the invention shown in the drawing are described in more detail below

1 shows an adjustable armchair in longitudinal section,

FIG. 2 likewise with a seat angle that is enlarged compared to the 'division shown in FIG. 1,

Fig. 3 also in the so-called lying position, Fig. 4 to 6 details of the adjustment mechanism in

larger scale, according to the "in · 1 to 3 shown scoring and back positions de3 adjustable armchairs,

7ig. 7 shows a further embodiment of an adjusting gear in which the Pig. 4 corresponding position.

The adjustable armchair consists essentially of a frame formed by two armrests 2 rigidly connected to one another by frames 1, an esselits 3 * an esseirücken 4 and a footrest «5 · On each of the two armrests 2 are each at the points u + 7 a" Swing arm 8 blew. 9 articulated, which aim downwards. The back 4 is attached to the swing arms 0. The arms 8 + 9, each side are bridged with a coupling 10. From the latter an arm 11 strives downwards which the rocker 9 is articulated at point 12.

4n the coupling 10 are in the points 13 + 1 ^ - aiming upwards Swing 15 + 16 articulated, at the free end parts one of the r: 3 load-bearing couplings 17 an ^ elenk. Is. From the rocker 8 strives

a rigidly attached lever 18 on which a roller 19 rotates is stored. The latter engages in those shown in FIGS. 1, 2 ″ and 4, 5 Armchair positions in one of the "chwings 15" molded Fork 20 a. In the? Ig. 3- ^ 6 corresponds to the "great 19" a curve 21forated on the rocker arm 15. The chv / inpre is extended beyond the hinge point 14 and controls the fold-out footrest 5

In Fig. 7, a handlebar "2" is on the lever 18 as a control element hinged for the seat 3, the upper end part around the upper Articulation axis 23 of the rocker 15 can hinge.

All new disclosed in the description and / or drawing Individual and combination features are essential to the invention viewed.
