Abstract

PROBLEM TO BE SOLVED: To obtain a cushion material for cushion members for beds, mattresses for beds, floor cushions, seat cushions of wheelchairs, and backrest mats for seats of automobiles. SOLUTION: A hot melt synthetic resin filament is extruded into the air from each of nozzles arranged at prescribed intervals. The filaments are freely mutually coiled vertically and laterally due to their adhesivity, the action of their gravity and other physical and chemical actions and solidified at their coiled state. A prescribed number of cup-shaped filament bulges are formed in the lateral direction at prescribed intervals and these bulges are mutually connected through laterally running filaments running left and right and also through longitudinally running filaments running front and rear, and thus the cup shaped bulges are connected and bulged laterally left and right and longitudinally front and rear at prescribed intervals.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The cushion material of the present invention will now be described with reference to the embodiments shown in the drawings. Although not shown, high-temperature molten synthetic resin filaments are extracted into the air from nozzles arranged at required intervals, -While being coiled freely by the right and left and its own adhesive force, gravitational action, and other physical and chemical actions, it is immersed in a coolant or the like and solidified into its coiled state. As shown, a required number of cup-shaped filament ridges 1a, 1a,... Are raised at required intervals in the left and right lateral directions, and the filament ridges 1a, 1a,. Are connected by the hanging filaments 1b, 1b,... And the filaments 1a, 1a,.
c, ..., and the cup-shaped filament ridges 1a, 1a,
Are connected to each other to form the cushion material main body 1.

FIG. 4 is a longitudinal sectional side view showing an embodiment in which a cushion material 3 is formed by attaching a gas permeable nonwoven fabric 2 to the bottom surface of the cushion material body 1.

FIG. 5 is a partial plan view of the upper sheet 4.
It is arranged on the upper surface of the cushion material 3 of the above embodiment. Although not shown, the upper sheet 4 shown in the figure is formed by discharging high-temperature molten elastic synthetic resin filaments from nozzles arranged at required intervals, and connecting and solidifying the filaments in a plane. The upper sheet 4 may be made of a plate-like elastic body having a suitable thickness instead of the above-described manufacturing method. Although not shown, the elastic body is a flat or curved plate having a smooth or uneven surface. It may be. The degree of elasticity and the use or required cushion performance can be freely selected.

FIG. 6 is a vertical sectional side view of a cushion material 5 according to an embodiment in which an air-permeable nonwoven fabric 2 is adhered to the bottom surface of the cushion material body 1 and an upper sheet 4 is combined and provided on the upper surface of the cushion material 3. It is.

FIG. 7 is a longitudinal sectional side view showing a combination embodiment in which several cushioning materials 3 of the above embodiment are stacked and an upper sheet 4 is stacked on the uppermost surface.

As shown in FIG. 8, the cushion material main body 1 is constituted by divided cushion material bodies 11, 12 and 13 having different cushion elasticities, and these divided cushion material bodies 11, 12 and 13 are flush with each other. , The seating surface can be configured to have a cushion distribution suitable for a specific person, for example.

Since the cushion material body 1 of the present invention is configured as described above, the elasticity can be selected by appropriately changing the material and thickness of the filament, and good cushioning properties can be obtained. Things come. Further, a space is formed between the filament protrusions 1a, 1a, and good air permeability is secured.

Further, since the cushion material 3 is formed by adhering the air-permeable nonwoven fabric 2 to the bottom surface of the cushion material body 1, the bottom surface of the cushion material body 1 is reinforced and may spread spontaneously when subjected to a pressing force. In other words, a sufficient cushioning property is ensured.

Further, by disposing the elastic upper sheet 4 on the upper surface of the cushion material main body 1, the area of the top end of the filament ridges 1a, 1a,... Thus, the pressure per unit area can be reduced, and good cushioning properties can be secured.

A cushion material body having a cushion material body with a cushion distribution arbitrarily changed by dividing the cushion material body with different elasticities and combining the divided cushion material bodies with different elasticities on the same surface. For example, it can be used as a cushion material for a wheelchair having different cushion elasticities depending on users.
