Spring core with coil springs and cushioning layer
The granted patent US12048380B2 introduces a novel spring core design that incorporates a plurality of coil springs, each featuring an upper and lower portion that together create an interior cavity. Each coil spring is encased in a fabric pocket, which includes a top area that covers the upper portion and a bottom area that covers the lower portion. A continuous upper fabric layer is positioned over the top area of these fabric pockets. Additionally, a cushioning layer is placed atop the coil springs, characterized by a bottom surface that is adjacent to both the coil springs and the continuous upper fabric layer. This cushioning layer is made from a liquid foam precursor that is poured onto the upper fabric layer, filling the recesses of the coil springs and bonding to the upper fabric layer upon curing.
Further claims detail the construction and attachment methods of the spring core. Specifically, the top area of each fabric pocket is affixed to the continuous upper fabric layer, potentially through ultrasonic welding. The design also allows the top area of each fabric pocket to define a recess that extends into the interior cavity of the coil springs, with the cushioning layer extending into this recess. Additionally, the top and bottom areas of each fabric pocket are connected within the interior cavity of each coil spring, enhancing the structural integrity and functionality of the spring core. This innovative design aims to improve the performance and comfort of products utilizing such spring cores, such as mattresses or seating solutions.
