The present invention provides a deformation detection sensor which combines a magnetic resin dispersing a magnetic filler in a resin with a magnetic sensor, of which stability of detection property is highly enhanced. The present invention thus provides a deformation detection sensor which comprises: a magnetic resin-containing polymer foam which comprises a magnetic resin, in which a magnetic filler is contained, and a polymer foam in which the magnetic resin is included, and a magnetic sensor that detects a magnetic change caused by a deformation of the magnetic resin-containing polymer foam, wherein the magnetic resin has a convex portion on either a surface facing the magnetic sensor or a surface facing opposite to the magnetic sensor, and its production method.

The present invention discloses a cushion for providing a user to sit on. The cushion includes a base layer, a seat layer and a supporting portion. The seat layer is configured on the base layer for providing the user to sit on. The supporting portion is configured between the base layer and the seat layer for supporting the user's ischial tuberosity. The seat layer is made with the material of the good covering shape, thus it can release user's upper body, hips and legs. Furthermore, by using the hard supporting portion for supporting the user's ischial tuberosities, the cushion makes the weight of the user's upper body be transmitted uniformly to the seat layer. Therefore, the cushion can prevent the user's hips and legs from some physical pains such as sore, ache, and pain due to long period of partial stress.

A chair assembly includes a back support arrangement that includes a back frame member and a forwardly-facing surface configured to support a user, a four-bar linkage assembly including a first linkage member, a second linkage member, a third linkage member and a fourth linkage member each pivotably coupled to one another such that the four-bar linkage assembly includes an upper end that is adjustable between raised and lowered positions, and an arm rest assembly supported on the upper end of the four-bar linkage assembly, wherein a lower end of the four-bar linkage assembly is pivotably supported from an arm support structure for pivotable movement such that the upper end of the four-bar linkage assembly is movable between a first position and second position located laterally outward from the first position, and wherein the fifth pivot point is located forwardly of the back frame member.

A cushion pad of a vehicle seat including: a cushion member including a soft pad and a hard pad which is harder than the soft pad, the soft pad being integrated with the hard pad so as to wrap the hard pad without covering a mounting side surface of the hard pad, wherein a groove, which is opened to the mounting side and having a size large enough to receive an exuding piece generated during molding of the soft pad, is provided in a periphery of the mounting side surface of the hard pad.

A chair assembly includes a base structure defining upper and lower portions, and a support structure, a seat support structure having a forward portion pivotably connected to the upper portion of the base structure for rotation about a first pivot point and a rearward portion, a back support structure having a forward portion pivotably connected to the lower portion of the base structure for rotation about a second pivot point that is located below and rearward of the first pivot point, and an upwardly extending back portion that moves rearwardly and downwardly as the back support structure pivots and the back portion moves, and a control link pivotably coupled to the seat support structure for rotation about a third pivot point and to the back support structure for rotation about a fourth pivot point each located rearward of the first and second pivot points.

An upholstered panel assembly includes an upholstery component having a foam layer provided on a substrate layer. The upholstery component covers the face of a base structure and is retained releasably by clips. The clips extend along the edges of the panel assembly. The panel assembly may be particularly suitable for aircraft cabins.

A furniture device is disclosed comprising six individual pieces that interconnect to form a cube. The pieces include two substantially L-shaped side portions, one substantially L-shaped central portion adapted to fit between the two substantially L-shaped side portions, a substantially L-shaped top portion adapted to fit between the two substantially L-shaped side portions and on top of the substantially L-shaped central portion, and two arc-sided rectangle portions adapted to fit between the substantially L-shaped top portion and substantially L-shaped central portion. The six pieces can be arranged in a various forms.

A chair includes a backrest, a seat and legs. The seat includes a cushion formed with a net-like structure made of a thermoplastic resin and having a thickness, a seat plate configured to support the cushion, and an outer covering configured to cover the cushion. An upper surface of the cushion includes a first place that has a first hardness and that is configured to support a sitting person's buttock, a second place that is located outside of the first place when seen in a plan view and that has a second hardness higher than the first hardness, and a third place that is located outside of the second place when seen in a plan view and that has a third hardness higher than the second hardness.
