Recliner chair having a turning up and stretching out footrest mechanism
First Claim
1. Mechanism for simultaneously turning up and stretching out an extension part (12,112) relative to a reference part (1,101), comprisingat least one first, linearly extending telescopic sliding profile element (10,110), having a first profile part rigidly interconnected with said reference part and a second profile part (A) pivotally interconnected with said extension part via a first swivel point (S,S′
- ), andat least one hinging second, linearly extending telescopic sliding profile element, having a first profile part pivotally connected to a second swivel point (Z,Z′
), on said reference part, and a second profile part (B) rigidly interconnected with said extension part, and pivotally interconnected with said second profile part of said first, linearly extending profile element, via said first swivel point,wherein the first linearly extending profile element moves in only minor pivoting and translational movements, which are smaller than those of said at least one hinging second linearly extending profile element, to provide smooth operation of said mechanism.

Abstract
Mechanism for simultaneously turning up and stretching out an extension part (12,112) relative to a reference part (1,101),with a telescopic sliding profile element (10,110) connected to the reference part and to the extension part, The essentially fixed sliding profile element may be connected to said reference part via a pantograph framework The invention also relates to recliner chair constructions involving such mechanism for turning up and simultaneously stretching out a footrest.

9. Recliner chair construction comprising a footrest (12,112) which simultaneously turns up and stretches out relative to said chair (1,101), comprising
at least one first, linearly extending a telescopic sliding profile element (10,110), having a first profile part rigidly interconnected with said chair or a chair support part and a second profile part (A) pivotally interconnected with said footrest via a first swivel point (S,S′ - ), and
at least one hinging, second linearly extending telescopic sliding profile element, having a first profile part pivotally connected to a second swivel point (Z,Z′
), on the chair, and a second profile part rigidly interconnected with said footrest and pivotally interconnected with said second profile part of said first, linearly extending profile element, via said first swivel point,wherein the first linearly extending profile element means moves in only minor pivoting and translation movements, which are smaller than those of said at least one hinging second linearly extending profile element, to provide smooth operation of said mechanism. - View Dependent Claims (10, 11, 12, 13, 14)
