Abstract: Devices, systems, and methodologies for vehicle seats include selectively collapsible safety layers providing collapsible support to reduce impulse experienced by the seated passenger imparted by the vehicle seat, which can reduce the likelihood and/or extent of injury attributable to occurrences exceeding threshold momentum changes, such as transportation vehicle collisions.

Abstract: A chair has a seat portion and a leg portion. The seat portion and the leg portion are joined by a structure that allows that seat portion to wobble relative to the leg portion. The structure can include one or more resilient member to create the wobble and one or more motion restrictor member to limit the amount of wobble or prevent wobble.

Abstract: A bedding or seating product comprising a spring core including upper and lower border wires. Each of the border wires is generally rectangular in cross-section to reduce wire costs without compromising beam strength of the border wire. Each row of springs of the spring core may be made of a single piece of wire. The rows of springs may be arranged in side-by-side rows and columns and be connected with each other by helical lacing wires.

Abstract: A complex spring unit (10) comprises at least a first spring portion (12) and a second spring portion (14), which first and second spring portions are integrally formed, wherein the first spring portion is arranged in use to be placed under compression, and the second spring portion is arranged in use to be placed under tension, during compression of the complex spring unit.

Abstract: An energy management load limiting vehicle seat member or construction is shown with collision energy absorbing and anti-submarining features.

Abstract: A supporting shell for a seat is provided by carrying out in-seat measurements with a plurality of test subjects, wherein the test subjects sit down on a measuring mat placed on a neutral seat frame. The measuring mat has a readily displaceable filling and adapts to the contour of the body of the respective test subject. After the test subject has sat down on the measuring mat and before the test subject leaves the same, the filling inside the measuring mat is fixed in place by applying a negative pressure. The geometric data of the surface contour of the measuring mat are determined and stored for each test subject. The measured surface contours are then superimposed onto one another. This produces an average surface contour which can subsequently be further altered slightly for adaptation to large seat users, and therefore a modified surface contour is created as a basis for the production of the supporting shell of the seat.

Abstract: A multi-layered support structure provides ergonomic, adaptable seating support. The multi-layered support structure includes multiple cooperative layers to maximize global comfort and support while enhancing adaptation to localized variations in a load, such as in the load applied when a person sits in a chair. The cooperative layers each include elements such as pixels, springs, support rails, and other elements to provide this adaptable comfort and support. The multi-layered support structure also uses aligned material to provide a flexible yet durable support structure. Accordingly, the multi-layered support structure provides maximum comfort for a wide range of body shapes and sizes.

Abstract: A method for forming rotatable bases for offices chairs characterised by structurally joining together at least two half-shells to form overall a plurality of spokes, each consisting of an elongated box-shaped body, and a central ring into which a column is inserted.

Abstract: In a vehicle seat, a central support member typically consisting of wire mesh or grid and supports most of the load of the vehicle occupant via spring members, and undergoes a relatively large displacement when the occupant is seated in the seat. Thus, by detecting the displacements of various parts of the central support member, preferably peripheral parts thereof, the magnitude of the total load and distribution of the load can be evaluated both reliably and accurately. Additionally, displacement sensors for measuring such large displacements are relatively inexpensive and easy to handle. Also, such sensors would not interfere with the existing seat designs, and would not be adversely affected by the equipment of the seat such as seat heaters.

Abstract: A novel support for use with furniture having a spring-edge is provided that includes a coil assembly. The coil assembly is typically square or rectangular with top and bottom surfaces and a front edge that faces the front of the furniture piece. A bridge is secured to the top surface of the coil assembly to provide support for the spring-edge. The bridge extends outwardly away from the front edge of the coil assembly and is supported in the same plane as the top surface of the coil assembly by a series of wires. The wire supports terminate at and hold a stiffening member in place that forms the upper portion of the spring-edge. The stiffening member is used to attach a series of front springs to the bridge. These springs are held in place on their lower end by the frame of the piece of furniture.

Abstract: A coil seating assembly is provided for use in a piece of furniture. The assembly includes a plurality of spring coils and a casing within which the coils are received. The coils each define a central longitudinal axis and are deformable in the direction of the axis between an extended, unloaded condition and a compressed, loaded condition. The casing includes a plurality of pockets, each of which encases one of the spring coils and includes side, top and bottom walls that collectively define an interior space sized for receipt of the coil when the coil is deformed from the unloaded condition. The pockets are sized to restrict extension of the coils from the compressed, loaded condition such that the coils are maintained in the loaded condition within the pocket. The pocketed coils are arranged in rows, and a plurality of the rows of pocketed coils are secured together by one or more cover sheets to form the assembly.

Abstract: A seat assembly with a frame supporting a spring construction therein for providing resilient support to a user. The spring construction having parallel sinuous springs and plural coil springs connected together by upper stabilizer wires. Support wires are secured to the coil springs at their bottom turns by transversely laid stabilizer wires and tie wires.
