A piece of seating furniture having a seat part, a back part, a chassis, and an at least two-part leg rest pivotably. The parts of the leg rest can be slid relative to each other during the pivoting. A part of the leg rest is formed by a telescoping leg-rest element which is retracted when the leg rest is pivoted in and is extended, in order to increase the length of the leg rest, when the leg rest is pivoted out. A first articulated lever and a second articulated lever are articulated to the seat part, a third articulated lever and a fourth articulated lever are each connected to a fifth articulated lever. A coupling lever and a control lever are articulated to the first articulated lever and/or the second articulated lever and/or to the third articulated lever and/or the fourth articulated lever.

A stretching device for a leisure chair includes a base. Stretching assemblies are symmetrically and pivotally connected to two sides of the base. The stretching assembly includes a seat plate mechanism. The front part of the seat plate mechanism is pivotally connected to a leg mechanism. The rear part of the seat plate mechanism is pivotally connected to a backrest mechanism. A drive mechanism is provided between the stretching assemblies. The drive mechanism includes a front drive rod and a rear drive rod. The front drive rod and the rear drive rod drive the stretching assemblies to unfold or fold by a reciprocating motion device. Two ends of the front drive rod are fixedly connected to the leg mechanism. Two ends of the rear drive rod are pivotally connected to a first drive member. The middle part of the first drive member is pivotally connected to a second drive member.

A footrest mechanism, comprising a chair support body, a locking component and a leg component. The locking component comprises a locking rod, a locking arm and a locking elastic member. The locking rod is pivotally connected to the chair support structure. The locking arm is pivotally connected to the leg component and the locking rod, respectively. The locking elastic member is connected to the chair support structure and the locking arm, respectively. The locking arm can be locked to the chair support structure to define a locking state and the locking state can be maintained due to an elastic deformation of the locking elastic member. The leg component is pivotally connected to the chair support structure and in a transmission connection with a driving component, and the leg component is capable of rotating relative to the chair support structure when the leg component is driven by the driving component.

A foot-lifting device for sofas, comprising: a fixed element configured to be constrained in substantially vertical position to the front portion of the structure of a sofa; a footrest which is movable with respect to the fixed element between a closed configuration and an open configuration; a connection kinematism of the footrest to the fixed element; in a closed configuration the footrest is substantially vertical, in open configuration the footrest is in rotated position upwards and translated onwards with respect to the sofa with respect to the position assumed in closed configuration, in that in both the open and closed configurations the extension of the device is wholly in front of the front portion of the structure of the sofa, and in that the kinematism comprises a chain of four articulated quadrilaterals, wherein: both the first and the second quadrilateral comprise a side integral to the fixed element.

The present disclosure relates to a mechanical stretching device for a movable seat unit, and a movable seat unit thereof. The mechanical stretching device includes: a linkage support that comprises a support structure configured to support the mechanical stretching device on ground and a linkage structure attachable to a seating portion of the seat unit; a back mechanism that is pivotally connected to the linkage support and is configured to attach to a backrest of the seat unit; and a leg stretching structure including a footrest element, and the leg stretching structure is pivotally connected to the linkage support, and the footrest element is attached to a footrest of the seat unit. The mechanical stretching device is configured to implement a sequential conversion or a reverse sequential conversion of the seat unit from a sitting state to a relaxing state and to a lying state.

A reclining chair assembly includes a reclining chair that has a backrest portion and a chair portion for having a user sit therein. A pair of footrests is each disposed on the chair portion of the reclining chair and each of the footrests is positionable in a lowered position or a raised position to raise the respective user's leg. Moreover, the pair of footrests is independently positionable in the raised position to facilitate one of the user's legs to be lifted while the other of the user's legs is not lifted. A pair of lifting units is each in mechanical communication with a respective one of the pair of footrests. Each of the lifting units independently urges the respective footrest into the raised position or the lowered position.

The present disclosure provides a footrest mechanism, a chair support structure and a chair. The footrest mechanism comprises a first support component, a first folding arm, a first rotating member and a first leg connecting rod, which can define a first four-bar mechanism. The first leg connecting rod is connected to the chair component, and is pivotally connected to the first rotating member. The first folding arm is pivotally connected to the first rotating member and the first support component, respectively. The first support component is pivotally connected to the first leg connecting rod.
