Abstract

The invention relates to a height-adjustable supple member for lying and/or sitting furniture, including one or more adjustable springs and a rotary part. Each adjustable spring is configured to change in height along a central axis under the effect of a radial stress relative to the central axis. The rotary part includes one or more rails each extending over an angular sector about the central axis, in a plane perpendicular to the central axis, from a first end to a second end more distant from the central axis than the first end. Each rail cooperates, in the radial direction relative to the central axis, with a corresponding adjustable spring among the one or more adjustable. The rotary part is able to rotate, about the central axis, so as to exert, through each rail, said radial stress on the corresponding adjustable spring.

Abstract

The invention relates to a flexible member with adjustable stiffness for lying and/or sitting furniture. This member includes one or more inner spring(s) oriented along a central axis, one or more pair(s) of outer helical springs about the central axis, and a rotating part able to rotate, about the central axis, between a blocking position and an unblocking position. Each pair of outer helical springs includes an upper outer helical spring and a lower outer helical spring, connected by a corresponding hinge, which has a pivot axis orthogonal to the central axis. In the blocking position, the rails engage the corresponding hinges of the pairs of the outer helical spring, so as to prevent radial displacement, relative to the central axis, of the corresponding hinges, while the unblocking position allows the radial displacement of each corresponding hinge.

Abstract

The invention relates to the field of beds or seats. In particular, the invention relates to a flexible element (10) stiffness that is adjustable stiffness along a compression axis (Z), the element including a compression spring (50). In order to enable the stiffness of the stiffness element (10) to be adjusted, it further comprises both a mechanism (150) coupled to the compression spring (50) so as to be actuated by compression of the compression spring (50) along the compression axis (Z) to move in a direction other than the direction of the compression axis (Z), and also an adjustment device for selectively restricting or releasing the movement of the mechanism (150). The invention also provides a unit (200) comprising a plurality of such flexible elements (10), and a method of adjusting the stiffness of the flexible element (10).

Abstract

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.

Abstract

The invention relates to a one-piece suspension device for interposing between a mattress and a support structure. The device includes a platform defining a bearing plane for the mattress, a fastener point for fastening to the support structure, and a resilient section. The resilient section is more resilient than the platform in a direction perpendicular to the bearing plane and it is interposed between the platform and the fastener point in the direction perpendicular to the bearing plane to absorb compression forces. The one-piece suspension device is shaped such that any axis perpendicular to the bearing plane and passing through the one-piece suspension device intersects the one-piece suspension device along a single intersection segment. The resilient section has at least two elastic hinges with different flexibilities.
