Abstract: A spring-support lath for supporting upholstery of furniture includes a lath body defining a longitudinal direction and having a pair of longitudinally extending U-profiles. Each U-profile is of U-shaped cross-section open in a downward direction and spaced apart in a lateral direction. The U-profiles are interconnected at their longitudinally spaced ends by end pieces and by fixed links situated intermediate the end pieces. The fixed links are spaced apart longitudinally, and at least some of the fixed links include a fastener structure such as a T-shaped member or an oblong hole for connecting to spring elements.

Abstract: A spring element for supporting a seat cushion or mattress includes a base body adapted to be attached to a foundation member. The base body includes a plurality of spring arms. Attached to the base body is a support body which includes at least two support arms. The support body is rotatable relative to the base body about an axis to displace the support arms between a supporting position to limit the deflection of the spring arms, and a non-supporting position to exert no influence on the spring arms. Therefore, the flexibility of the spring element can be adjusted by rotation of the support body.

Abstract: The invention relates to a bearing element having a base plate fitted on a support, for a seat or bed system, with a bearing plate to hold upholstery. The invention seeks to produce a bearing element whose range of spring is approximately equal to the total height, and which is easy to produce. To this end, at least two spring elements serving as bearing arms (12, 22) are fitted between the base plate (11, 21) and the bearing plate (15, 25). These spring elements, configured like leaf springs, are directed outwards from the base plate (11, 21). Their outer ends join the hearing plate (15, 25). In another version of the invention, a spring body (35, 35′) is fitted between the base and bearing plate. The spring body head (35.2) and foot (35.1), like the bearing plate and base plate, have corresponding locking parts, so that the bearing plate can also be removably placed on the spring body (15, 15′) and on the base plate (21).

Abstract: A cushioning support for a mattress comprises a plurality of elements forming a grid structure. Compression springs are mounted on respective ones of the elements. Bearing plates are disposed atop respective ones of the springs, and are disposed closely adjacent one another to form together a support surface for the mattress. The baseplates are removably interconnected so that the size and shape of the cushioning support can be varied to conform to the size and shape of a cushion to be supported. The springs can be detachably connected to the elements, or of one piece construction therewith.

Abstract: A cushioning assembly comprises a foundation, a plurality of springs mounted on the foundation, and a pad resting on the springs. Each spring is formed of plastic and forms a through-chamber having an axis. The axes of the springs lie in a common plane oriented perpendicular to the loading applied thereto when a user rests on the assembly. Pad-supporting plates are removably attached to the spring bodies, e.g., by clamp members.

Abstract: The present invention relates to an adjustable swivel chair with a pivoting angular holder for the backrest. The angular holder for the backrest is provided into an upper portion and an offset arm so as to allow for the articulated movement of the parts with respect to one another. The offset arm extends under the seating surface while the upper portion provides a support for the backrest. Adjustment means are provided in the form of frictional engagement of lamellar packs and the clamping thereof by means of a clamping adjustment device which may be released so as to position the movable elements with respect to one another. The assembly is mounted on a support post and the upper external portion of the support element defines the seat portion of the swivel chair.
