Chair with rearwardly inclinable seat and back rest carrier
First Claim
1. A reclining chair, comprising:
- seat support means including means defining a first substantially horizontal pivot axis and a second substantially horizontal pivot axis extending in mutually spaced relationship;
rearwardly inclinable seat carrier means pivotable about said first substantially horizontal pivot axis and having a rear end;
rearwardly inclinable back rest carrier means pivotable relative to said second substantially horizontal pivot axis and having a back rest region;
means coupling said rearwardly inclinable seat carrier means to said rearwardly inclinable back rest carrier means such that rearward inclinations of said rearwardly inclinable seat carrier means and of said rearwardly inclinable back rest carrier means occur conjointly and such that an ensuing downward motion of said rear end is less than an ensuing downward motion of said back rest region;
back rest means translatably guided on said rearwardly inclinable back rest carrier means; and
linkage means interconnecting said rear end of said rearwardly inclinable seat carrier means, said back rest region of said rearwardly inclinable back rest carrier means and said back rest means such that said rearward inclinations cause a downward movement of said back rest means approximately equal to said downward movement of said rear edge of said rearwardly inclinable seat carrier means.

Abstract
A seat carrier and a back rest carrier are linked by pivot joints through a lever to a carrying or swivelling component. At the end of the seat carrier on the back rest side there is connected a chain of link members which at its other end is connected to a slide and a back rest. When the chair inclines towards the rear, the chain of link members causes the slide and the back rest to conjointly move in a downwards direction. The so-called undressing effect caused by the change-over from the normal position into the rearwardly inclined position of the back rest is eliminated in a simple and space saving manner and without exploiting the space below the seat carrier. By arranging a spring element, for instance a gas spring, in the knee region of the chair, ready access can be had to the spring element for arresting it.

5. A chair frame for a reclining chair including:
-
seat support means including means defining a first substantially horizontal pivot axis and a second substantially horizontal pivot axis extending in mutually spaced relationship; rearwardly inclinable seat carrier means pivotable about said first substantially horizontal pivot axis and having a rear end; rearwardly inclinable back rest carrier means pivotable relative to said second substantially horizontal pivot axis and having a back rest region; means coupling said rearwardly inclinable seat carrier means to said rearwardly inclinable back rest carrier means such that rearward inclinations of said rearwardly inclinable seat carrier means and of said rearwardly inclinable back rest carrier means occur conjointly and such that an ensuing downward motion of said rear end is less than an ensuing downward motion of said back rest region; back rest means translatably guided on said rearwardly inclinable back rest carrier means; linkage means interconnecting said rear end of said rearwardly inclinable seat carrier means, said back rest region of said rearwardly inclinable back rest carrier means and said back rest means such that said rearward inclinations cause a downward movement of said back rest means approximately equal to said downward movement of said rear edge of said rearwardly inclinable seat carrier means, wherein such chair frame comprises; spring means for counteracting said rearward inclinations and having a first end and a second end; means for pivotably connecting said first end of said spring means to said seat support means and lever means for pivotably connecting said second end of said spring means to said rearwardly inclinable back rest carrier means. - View Dependent Claims (6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20)
