DE8327752U1 - ADJUSTABLE ARMCHAIR - Google Patents

Description

The invention relates to an adjustable chair Art specified in the preamble of claim 1.

The invention is based on a known from DE-OS 31 36 078 Verste.1.lsessel with changeable Seat and backrest inclination and one adjustable footrest and armrests attached to the seat.

Furthermore, one of the people sitting in the Se si is manual here actuatable adjusting member provided, with the help of which the. desired position of use of the Armchair can be adjusted.

The adjusting element is designed as a two-armed lever and is arranged in the lower part of the seat Adjustment mechanism inserted so that it can be pivoted about an axis directed transversely to the armchair.

In addition, the power arm of the lever-like adjusting element arranged to the side of the seat and protrudes between the seat and the adjacent armrest

beyond the seat.

However, this means that there must be sufficient free space between the seat and the adjacent armrest in order to be able to pivot the adjusting member. Nevertheless, with such an arrangement of the adjusting element, the risk of damage to the seat and armrest cushions is relatively high.

The adjusting element also represents a considerable hindrance and danger to the person sitting in the armchair. If the adjusting element should be arranged in a niche in the armrest, the obstruction of the person sitting in the armchair is
Adjustment reduced, but this arrangement requires a relatively complicated design - at least the armrests.

The object of the invention is now to improve an adjustable armchair Λ pr in the preamble fies claim 1 specified A Vt .l.rcrt that while maintaining the advantage already achieved in the prior art, namely

Peitz 8195/83

that the reclining armchair can be comfortably and safely moved from the seated position with a manually operated adjusting element, i.e. without shifting the weight of the seated person, into another position of use, a design option for the armchair that is virtually independent of the adjusting element can be achieved with simple means and at the same time far more than before Disabilities and dangers to those sitting in the armchair are excluded.

The solution to this problem is characterized in that the lever on the seat exclusively below it is arranged so that his power arm in the Sitzsteliung of the chair is directed obliquely forward and down, that also on the lever arm a after upward directed and extending beyond the seat, flexible pulling element is arranged and that the lever load arm via a rod with the link chain links, is connected so that when pulling up the pulling element dei lever over the rod a pivoting movement of the gel chain handlebars from their rear division initiates forward.

With these measures, you are now largely more independent in the design of the armchair than before, since the in the grip area of the in

H e r through is now only a relative small pivot angle required for the lever having the pulling element, the smaller seat heights allows and or does not require any free space in the area of the seat, because the seat is connected to the initiation of the chair adjustment by means of the manually operable according to the invention Organ now over the following adjustment range due to the load on the person sitting in the armchair without any action is effected without the aforesaid Lever follows this pivoting movement.

The rod is preferably designed as a plunger and arranged facing forward from the lever.

To further simplify the above-described adjustable chair and to further improve the The function of the reclining armchair can be further developed as can be inferred from claims 7 and 8 will.

An embodiment of the invention is shown in the drawings and is described in more detail below.
Show it:

1 shows an adjustable armchair in the sitting position with the adjusting mechanism seen from the outside ,

Fig. 2 also in the so-called television position,

Fig. 3 also in the lying position.

This reclining armchair essentially comprises a Frame 1, a seat 2, a backrest 3, two armrests 4 attached to the seat 2 and one Footrest 5. To hold the seat on the frame 1, there is a link chain on each side of the seat intended. Each link chain has a frame plate 6, on which two of these are directed upwards Handlebars 7 and 8 are hinged.

At the free end of the lever 13, a pulling element 11 designed as a belt or belt is attached, which is passed between the seat 2 and the adjacent armrest A and protrudes upward beyond the seat 2. The pulling element 21 preferably ends at the top in a loop. Instead of this, a differently designed handle can also be provided under certain circumstances. A locking cam 22 and a detent 23 in the lower longitudinal side of the lever 13 are provided so that the detent cam engages positively in the detent 23 in the seated position of the armchair for inevitable and releasable fixation of the seat position on the frame plate 6. As a rule, the force of gravity acting on the lever is sufficient for this purpose, but under certain circumstances it may be advisable to provide a spring acting on the lever, which forces the lever 13 into the position shown in FIG.

All swivel axes of the adjustment mechanism are at right angles to the direction of adjustment of the chair arranged running.

Under certain circumstances it is also possible to design the rod as a pulling element in order to use the lever articulated rod 15 exert on the rear link forces to initiate the chair adjustment to be able to.

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