Abstract: Embodiments of the present disclosure relate to making polyurethane foam less likely to become separated from an in-mold foamed molded product unit, the in-mold foamed molded product unit including an in-mold foamed molded product and an insert material which are integrally provided. A foamed composite molded product is configured such that a portion of an insert material is exposed to an outside of an in-mold foamed molded product, and is in contact with polyurethane foam.

Abstract: A vehicle seat for a motor vehicle, includes an adjustable seat base, an adjustable backrest surface and adjustable lateral support elements provided on the seat-side and/or the backrest-side, wherein the size or geometry of the lateral support elements, which form a pair and are opposite each other, can variously be changed, and wherein the seat base and/or the backrest surface can be tilted towards one side, electromechanical or pneumatic adjustment means being provided for this purpose.

Abstract: A spring unit including a zigzag spring 40A, 40B; a first sliding unit 20A including a first spring securing part 22 securing a first end of the spring, a first spring accommodating part 28A, 28B accommodating the spring; first slide guiding parts 25 on both sides of the first sliding unit; a second sliding unit 30A including a second spring securing part 32 securing a second end of the spring, a second spring accommodating part 36A, 36B accommodating the spring, second slide guiding parts 35 on both sides of the second sliding unit, wherein the first and second slide guiding parts 20A and 30A are engaged to mutually slide, and the spring 40A, 40B is held inside a space formed between the first and second spring accommodating parts 28A, 28B, 36A, and 36B while the first and second slide guiding parts 25 and 35 are engaged.

Abstract: An interchangeable cover is secured between a lower base and an upper cover retention body over an inflatable dome. The entire assembly is placed on a chair for an individual to sit on for stability core training. The upper cover retention body and lower base detach from compressive engagement of the interchangeable cover to replace the cover as desired by the individual.

Abstract: The structure is formed by serially connecting a torsion bar and a coil spring via a arm and a supporting frame to thereby elastically support a flat-type supporting member, and by disposing a cushioning member for seat cushion provided with a spring characteristic closely analogous to a load-to-deflection characteristic (spring characteristic) of the muscle of a human body above the flat-type supporting member. Accordingly, it is possible to make a spring characteristic for working when supporting a load of a human different from a spring characteristic for working when removing vibration even with an extremely simple structure. In other words, the structure has an excellent function to make the spring constant at work when removing vibration, especially when removing a high frequency component.

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.
