The invention relates to a furniture device configured to receive the weight of a being, said furniture device having a holding arrangement and at least one section. The section comprises a base, a movable plate element, a moving mechanism and at least one elastic device. The plate element is configured to interact with the at least one elastic device and to be moved by the moving mechanism in respect to the base in order to adjust the firmness of the at least one elastic device. The elastic device comprises a pocket made of a fabric, and an elastic member, the elastic member is arranged within said pocket, the pocket is attached to adjacent pockets whereby the attachment is formed so that adjacent elastic devices may move independently from one another along a distance (A), as measured from a free end of the elastic device and in a direction perpendicular to the plate member. The holding arrangement comprises a connecting portion and a holding member, which is connected to the base or the plate element and connected to the at least one elastic device via the connecting portion, such that the at least one elastic member is compressed and relaxed respectively over its entire length during movement of the plate element upwards and downwards. The connecting portions are arranged on a straight line, which extends through the centre of two or more attached elastic devices and the holding member is a flexible thread or string, which is directly connected to each connecting portion.

In a preferred embodiment, a tilt-recline force adjusting apparatus for an aircraft passenger seat configured for a tilt-recline positioning includes a first spring having a first axis to urge a seat back into an upright position, the first spring arranged to compress as the seat is manually reclined, a helper spring having a second axis parallel to the first axis, the helper spring arranged to assist or counteract the first spring, an adjustment mechanism coupled to the helper spring to increase or decrease a force exerted by the helper spring to assist or counteract the first spring, and a weight sensing mechanism coupled to the adjustment mechanism and operable to actuate the adjustment mechanism in direct proportion to a weight of a seated passenger, whereby the force exerted on the aircraft seat to urge the seat back into an upright position is greater for a heavier seated passenger.

It is of interest to be able to adjust the upholstery firmness of furniture for sitting and lying on as individually as possible, in particular with a view to being able to use the furniture for a long time. In addition, there is a need for a design which allows firmness adjustment to be integrated and which can be realized as flexibly as possible for different furniture or seat variants. The invention provides an upholstered-furniture arrangement (100) which has a basic frame (7) and an upholstered cushion (6) on which someone can sit or lie, which is fixed to the basic frame at least in the edge region thereof and which has a panel (4) beneath it for upholstery-firmness adjustment, the panel being arranged in the basic frame (7) such that the height of the panel can be adjusted by pivoting the panel, wherein the end of the panel (4) located opposite a pivot shaft (14) is arranged freely in the basic frame (7), and a height-adjustment device acts on the panel (4) from beneath by applying an adjustable compressive/prestressing force (F), the height-adjustment device being supported in the downward direction by the basic frame, counter to the compressive/prestressing force. This arrangement has an attractive, direct technical effect and offers a good compromise between cost and benefit.

The invention relates to a furniture device configured to receive the weight of a being, said furniture device having a holding arrangement (20) and at least one section (30). The section (30) comprises a base (2), a movable plate element (6), a moving mechanism (4) and at least one elastic device (12). The plate element (6) is configured to interact with the at least one elastic device and to be moved by the moving mechanism in respect to the base in order to adjust the firmness of the at least one elastic device. The elastic device comprises a pocket (14) made of a fabric, and an elastic member (18), the elastic member is arranged within said pocket, the pocket is attached to adjacent pockets whereby the attachment (32, 32) is formed so that adjacent elastic devices may move independently from one another along a distance (A), as measured from a free end of the elastic device and in a direction perpendicular to the plate member. The holding arrangement comprises a connecting portion (26) and a holding member (22), which is connected to the at least one elastic device via the connecting portion, such that the at least one elastic member is compressed and relaxed over its entire length during movement of the plate element in a respective direction, wherein the connecting portions are arranged on a straight line, which extends through the center of two or more attached elastic devices.

The present invention discloses a chair reclining adjustment mechanism, including a chassis, a turntable rotatably connected to the chassis by using a rotation shaft, and an elastic resetting device that is disposed between the chassis and the turntable and is configured to always enable the turntable to have a moving trend of rotating towards one side of the rotation shaft, wherein a rotation gap is provided between the turntable and the chassis at the other side of the rotation shaft; the adjustment mechanism further includes a locking member capable of entering or slipping out of the rotation gap, a locking component that always enables the locking member to have a moving trend of entering the rotation gap and an unlocking component configured to pull the locking member to slip out of the rotation gap.

The present invention provides a chair and a chair lifting adjustment control mechanism thereof. The chair lifting adjustment control mechanism comprises a base, an executing member slidably connected to the base for pressing a pushbutton of a telescoping member, and a drive-by-wire assembly with one end connected to the executing member to enable the executing member to produce a horizontal displacement. The drive-by-wire assembly comprises a dragline with one end connected to the executing member, and the executing member has a driving ramp for facing the pushbutton and pressing or relaxing the pushbutton during the horizontal displacement.

The invention relates to the field of furnishing. In particular, the invention relates to a stiffness adjustment device movable between an interference position for imposing a restriction on the deformation of a seat, back or bedding spring, and a non-interference position for releasing the spring from the restriction. The stiffness adjustment device comprises a resilient element, e.g. such as a flexible blade and, as it moves between the interference and non-interference positions it passes through an intermediate position in which the resilient element is subjected to resilient bending that is greater than in the interference and non-interference positions.
