摘要： 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.

摘要： The left and right side linkages of a mechanism for a reclining chair are provided with respective pantographic linkage systems. An actuator link is provided for each, which causes the headrest which is mounted to the upper end of each such linkage system to rotate relatively forwards by about 90 degrees as the backrest is reclined as the chair goes from its fully erect to its TV and fully reclined positions. The mechanism provides low back, wall-saver operation for the chair reclining function without necessitating a thick or oddly appearing style.

摘要： The present invention relates to an operating device for a seat, an armchair or a couch, where the angle between the base (3) and the back(4) can be modified, so that the user can move from a sitting position to a position of relaxation, merely through the action of his body. The invention provides a retractable supporting means for the small of the back comprised of a flap (10) pivoting around an axis (11) and of a support (32) with a roller (33), integral with the base, and capable of positioning the retractable supporting means for the small of the back by pivoting the flap as the displacement of hte user's body proceeds.

摘要： A pivot fitting for moveable furniture parts on upholstered furniture has a first lever and a second lever that are mounted to as to pivot relative to each other about a common axis from a basic position through a predetermined angle. The pivot fitting also includes a clamping mechanism with which the two levers can be fixed relative to each other at different angular positions within the predetermined angle, the clamping mechanism has a toothing attached in a rotationally fixed manner on the second lever, at least one catch that is pivotally mounted on the first lever and loaded in the direction of the toothing, the catch engaging with the toothing in a detent position. A first control disc is mounted so as to pivot about the common axis, with which the at least one catch is disengageable from the toothing when the predetermined angle has been passed from the basic position into an adjusting direction, such that when the catch is disengaged from the toothing, the two levers can be pivoted back into the basic position when the predetermined angle is passed in a resetting direction. The first control disc can be carried by the toothing, resting thereon with a friction fit, and is mounted so as to pivot about a switching angle relative to the first lever and wherein a second control disc mounted so as to pivot about the common axis can be carried by the toothing and is mounted so as to pivot about a switching angle relative to the toothing.
