SEGMENTED TUBULAR CUSHION SPRINGS AND SPRING ASSEMBLY |
摘要 |
A spring (10) includes a tube (12) having an elliptical cross section, with the greater axial dimension extending laterally and the lesser axial dimension extending vertically. A plurality of cuts in the form of slots passing through most of a wall of the tube (12) extend perpendicularly to a longitudinal axis (16) extending along the tube (12). An uncut portion (26) of the tube wall extends along the tube (12) for bonding or fastening the tube to a suitable base, such as a bottom of a seat cushion. This invention simplifies the construction of and reduces the cost of spring-containing cushions and is useful where a shock-absorbing cushion is needed. |
