Abstract
In an air mattress (1) including a plurality of levels of air mattress layers (5, 7) which are vertically stacked, in each of the levels of air mattress layers (5, 7), flexible hollow air cells (43, 23) each extending along the width of the air mattress (1) are arranged in parallel with each other in the longitudinal direction of the air mattress (1), air cells (43, 23) in each of the upper air mattress layer (7) and the lower air mattress layer (5) are divided into a plurality of groups such that the air cells (43, 23) are expanded or contracted in units of the groups by supplying or discharging air to/from these air cells (43, 23).
Claims12
An air mattress, comprising:
- a plurality of levels of air mattress layers which are vertically stacked, wherein
- in each of the levels of air mattress layers, flexible hollow air cells each extending along a width of the air mattress are arranged in parallel with each other in a longitudinal direction of the air mattress,
- the plurality of levels of air mattress layers include an upper air mattress layer and a lower air mattress layer,
- the air cells in each of the upper and lower air mattress layers are divided into a plurality of groups such that the air cells are expanded or contracted in units of the groups by supplying or discharging air to/from the air cells in units of the groups, and
- each of the air cells in the upper air mattress layer has a width smaller than that of each of the air cells in the lower air mattress layer.
An air mattress, comprising:
- a plurality of levels of air mattress layers which are vertically stacked, wherein
- in each of the levels of air mattress layers, flexible hollow air cells each extending along a width of the air mattress are arranged in parallel with each other in a longitudinal direction of the air mattress,
- the plurality of levels of air mattress layers include an upper air mattress layer and a lower air mattress layer,
- the air cells in each of the upper and lower air mattress layers are divided into a plurality of groups such that the air cells are expanded or contracted in units of the groups by supplying or discharging air to/from the air cells in units of the groups,
- the air cells in the upper air mattress layer are formed by joining a lower sheet located on the lower air mattress layer and an upper sheet located on top of the lower sheet to each other in portions which are spaced from each other at a predetermined distance in a longitudinal direction of the air mattress, and
- in a cross section of the air cells, an upper surface portion made of the upper sheet is longer than a lower surface portion made of the lower sheet.
An air mattress, comprising:
- a plurality of levels of air mattress layers which are vertically stacked, wherein
- in each of the levels of air mattress layers, flexible hollow air cells each extending along a width of the air mattress are arranged in parallel with each other in a longitudinal direction of the air mattress,
- the plurality of levels of air mattress layers include an upper air mattress layer and a lower air mattress layer,
- the air cells in each of the upper and lower air mattress layers are divided into a plurality of groups such that the air cells are expanded or contracted in units of the groups by supplying or discharging air to/from the air cells in units of the groups, and
- in at least one of the upper and lower air mattress layers, a slit extending along the width of the air mattress is formed between adjacent ones of the air cells in a predetermined area.
