Abstract: The present invention relates to a supporting module (100) for use in an adaptive sleep system and to a sleep system comprising such supporting modules, the resistance (resilience) of which can be adapted in a simple manner to the anatomy and/or posture of a user.

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: A body support apparatus, for example, a bed, includes a support surface defined by support members. Each support member is mounted for movement in a direction substantially normal to the support surface. Support members are so arranged that movement of any one of the support members in a direction substantially normal to the support surface and beyond a threshold distance relative to an adjacent support member causes movement in substantially the same direction of said adjacent support member. No movement of a support member is caused by the movement of an adjacent support member when the distance of relative movement is below the threshold distance. The support members are resiliently urged towards an unloaded position, by tension springs.

Abstract: A bed assembly is disclosed for use within a moving vehicle which vehicle includes a base support floor and a plurality of side wall members. The bed assembly includes a frame adapted to support a mattress and which has a generally rectangular perimeter. A plurality of attachment members are secured to the vehicle and are spaced about the perimeter of the frame. A plurality of tension elements interconnect the frame and the attachment members. Finally, a plurality of adjustable shock absorbing and dampening devices interconnect the frame and the vehicle base support floor to provide vertical support to the frame. The shock absorbing and dampening devices are aligned angularly relative to the frame to cooperate with the tension elements to dampen the fore-and-aft, lateral and vertical motion of the frame relative to the vehicle base support floor and side wall members during movement of the vehicle.

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 mattress is provided with an innerspring unit, one or more layers of foam material disposed over the innerspring unit, and a mattress cover enclosing the innerspring unit and foam layers. The innerspring unit has first and second border wires spaced apart from each other by a predetermined distance and a plurality of spring coils arranged in a plurality of rows between the border wires. Each of the coils is formed of a helical wire member having a plurality of spaced apart convolutions. A plurality of compressible support members are provided between adjacent rows of coils. The support members are generally in the shape of an I-beam, with an upper portion of a first width, a middle portion of a second width, and a lower portion of a third width. The upper portion of each support member is provided between a first two adjacent convolutions of the coil springs and the lower portion of each support member is provided between a second two adjacent convolutions of the coils.

Abstract: The present invention relates to a spring assembly for the seat portions or areas of upholstered furniture. The spring assembly provides a frame and a series of different spring types supported in a generally parallel arrangement within the frame. The spring assembly inlcudes a plurality of upper spaced, elongate sinuous springs extending between and above a pair of opposing front and back members. Located in the central region of the assembly is a rectangular quad coil spring mounted on two upper and lower wire stringers. The spring assembly is provided with a pair of Z-shaped sinuous springs, one located on each lateral side of the quad coil. The Z-shaped springs are mounted on lower elongate sinuous springs extending between the front and back members. The upper portions of the Z-shaped sinuous springs and the upper elongated sinuous springs are secured to the upper and lower stringers for stability and to prevent lateral movement of same.

Abstract: An improved spring is provided which may be used in cushions, mattresses, or box springs which includes a limiting internal member. This limiting member assist in limiting the longitudinal deflection of the springs. Also provided are snapped-fitting connections between the spring and a grid for use within a box spring. Also provided is a "floating" portion of a peripheral border wire, particularly suitable for use in a pair of box springs beneath a king-size mattress unit. Also provided is a corner guard which provided support for upholstered fabric on a box spring. Finally, an improved borderwireless mattress using a peripheral band is provided, which allows the mattress to bend more easily, without disadvantageous setting of its border wires.

Abstract: A bedding unit such as a box spring has springs with lower portions mounted on the frame of the unit, upper portions connected to the wire grid of the unit, and midportions which are collapsible to support the grid resiliently on the frame. The upper portion of a corner spring includes a vertically uncompressible loop which contacts the frame when the midportion is collapsed, thereby limiting the deflection of the spring. The loop also prevents the filler material fo the unit from collapsing inwardly. The main springs of the unit have upper portions which have hooks for engaging the grid wires of the unit. These hooks are located at opposite ends of the wire which forms the spring. The upper portions have transverse bars which are connected to the hooks by connecting sections.

Abstract: A bedding unit spring has an upper portion attached to a grid, a lower portion attached to a frame, and a vertically collapsible midportion which connects the upper portion to the lower portion. The upper portion of a spring may have two transverse bars at its ends, a third transverse bar at its center, and a center bar formed of two sections which are on opposite sides of the third transverse bar. The center bar sections are directed toward the midportions of the end transverse bars. A deflection limiter member is attached to the spring to limit the collapsing movement of the spring and to increase the effective stiffness of the spring. It is formed of a wire which has an abutment portion and two connector bar portions. The connector bar portions extend at different inclination angles from the abutment portion to the spring.

Abstract: A bedding unit utilizes formed wire springs for supporting a wire grid on a frame. A spring has an upper portion which has two transverse bars, a longitudinal center bar located between and spaced from the transverse bars, and connecting sections which connect the opposite ends of the center bar to the ends of the transverse bars. Under compression, the upper portion of the spring or a grid wire attached thereto contacts a torsion bar in the spring. Some embodiments have a continuous and uninterrupted lower portion and an upper portion with two sections which terminate in the ends of the spring wire.
