A structure intends to arrange the appearance of furniture at a connecting portion between a first member having stiffness and a second member movable relative to the first member and having stiffness without forming the connecting portion in an unnaturally large diameter. More specifically, the present invention provides a structure for connecting members comprising: a first member having stiffness; a second member movable relative to the first member and having stiffness; and a spring member in which an end portion thereof is connected to the first member and other end portion thereof is connected to the second member so as to accumulate a reaction force by elastic deformation, wherein the spring member is formed into a frame-like shape extending along the first and second members.

An automotive slouch rear seat with improved adjustability is provided including an upper seat back and a lower seat bottom. The upper seat back includes a fixed rear seat back, a pivotal seat back, and a sliding seat back. The pivotal seat back has an upper end and a lower end for connecting to the lower seat bottom. The sliding seat back is slidably engaged to the fixed rear seat back. The sliding seat back is rotatably engaged to the upper end of the pivotal seat back. The lower seat bottom includes a fixed rear seat bottom, and a sliding seat lower. The sliding seat lower is slidably engaged to the fixed rear seat bottom. The sliding seat lower is rotatably engaged to the lower end of the pivotal seat back. Also, an automotive slouch rear seat assembly and a method of assembling a pre-installation automotive slouch rear seat assembly are provided.

A task chair, including a backrest assembly and a seat assembly pivotally coupled both to one another and to side portions of a fixed yoke member for synchronized movement, in which the seat of the seat assembly moves upwardly and forwardly concurrently with recline of the backrest of the backrest assembly. The chair further includes a tension assembly including an elongate tension member, such as a leaf spring, secured at one end thereof to the yoke member, and a contact member, such as a contact roller, adjustably mounted to the seat assembly. The contact member engages the tension member such that the tension member resists recline of the backrest assembly and concurrent movement of the seat assembly from their initial positions, and also provides a restoring force which tends to move the backrest to its initial upright position and the seat to its initial rearward and lowered position. The contact member is adjustable with respect to the tension member in order to vary the effective moment arm acting upon the tension member, thereby varying the pre-load of the tension member and the resistance provided by the tension member.

A chair of the tilting type which includes a base, a seat and back, with the base pivotally supporting the seat with two parallel links of a four-bar parallel linkage, with one of the links extending to support the back. The four-bar linkage is duplicated on each side of the chair by forming the two opposite parallel links or cranks from the upturned ends of the tubes which pass through the base in parallel but vertically offset fashion, the base thus forming the fixed bar of the linkage with its opposite bar or coupler being formed by the seat. A spring within the base is operative on one (of both) of the tubes to urge the chair to an upright position. The tubes are pivotally connected to the seat and one of the tubes extends and is fixedly connected to the back. As the back tilts, the four-bar mechanism is engaged and lifts the seat which thereby uses the occupant's weight to counteract the reclining.Also disclosed is an adjustable armrest that can readily raised, or lowered, and optionally rotated in a horizontal plane.A further aspect of the present disclosure is a headrest that is pushed into place when the chair is reclined and retracted when the chair returns to an upright position.
