Abstract:
PROBLEM TO BE SOLVED: To provide row-shaped pocket coils improving usability by fitting the row-shaped pocket coils to a body of a user when being used as cushioning materials of a mattress or the like by preventing coils from being deformed in a wide range due to deformation of a cover.SOLUTION: The row-shaped pocket coils (3) according to the present invention are formed by partitioning the inside of a hollow cover (5) by a plurality of coil chambers (9) aligned in a row shape and storing coils (6) in the respective coil chambers (9). The cover (5) includes: connection parts (10) in which adjacent coil chambers (9 and 9) are connected; and separation parts (11) in which upper ends of the adjacent coil chambers (9 and 9) are separated. In the present invention, the length of the connection part (10) is defined shorter than the length of the coil (6) in a most contracted state.SELECTED DRAWING: Figure 2
