Detailed Description

The following will explain the technical solution of the present invention with reference to the accompanying drawings

An air cushion bed comprises a variable-angle rigid layer 1, an elastic supporting layer 2 and an air bag layer 3, wherein the variable-angle rigid layer 1 is at least divided into four areas, a gap 13 is reserved between each area, four air cylinders 4 are arranged below each area and used for supporting the four corners, and the air cylinders 4 control the overturning of the areas; the elastic supporting layer 2 completely covers the rigid layer 1, air holes 5 are formed in the upper surface and the lower surface of the elastic layer 2, an elastic body 6 is arranged in the elastic layer 2, and the elastic body 6 and the air holes 5 are arranged at intervals; the air bag layer 3 completely covers the elastic supporting layer 2, the air bag layer 3 is formed by splicing at least three wavy air bags 14 in the left, middle and right directions, the wavy air bags are opposite in wave crest and opposite in wave trough, and the three air bags 14 in the left, middle and right directions are respectively and independently provided with an inflation inlet 7. When the angle-variable rigid layer 1 is used, the angle can be adjusted in a partition mode through the air cylinder 4, and when the user needs to turn over left and right or adjust front and back, the user can adjust the ejection height of the air cylinder to create different angles. Because the angle between four subregion is not necessarily very unanimous, in order to overcome the problem of people's travelling comfort, the elastic support layer 2 just can play the effect of buffering, the elastic support layer 2 is very soft, can support the human body and make the user very comfortable simultaneously, also can eliminate simultaneously the inconsistent problem in four regions of rigid layer 1 when the removal changes of variable angle has improved the travelling comfort that the user couched, and gas pocket 5 can play ventilative effect simultaneously. The gasbag layer 3, as the part that directly contacts with the user, adjustable gas filled design can make gasbag compliance adjustable, has promoted the comfort level of lying, and split type design has not only improved the travelling comfort of mattress, has also improved the suitability of mattress, and the user need not to be from the regulation that the pad also can be arbitrary the angle in each region of the rigid layer 1 of variable angle has promoted the user and has lain the experience.

Preferably, the left, middle and right wavy air bags 14 are provided with connecting pieces 8 at the wave troughs to fixedly connect the air bags 14 with each other. The connecting piece 8 makes the integrity of the air bag layer 3 better, and any lying posture can not change the positions of the three wavy air bags 14 and can not influence the functions of the variable-angle rigid layer 1 and the elastic supporting layer 2.

The elastic body 6 is a spring 9, and the spring 9 is arranged in a hole vertically penetrating between the upper surface and the lower surface. This design makes the resilient support layer 2 more flexible and more adaptable as a cushioning layer.

In said gap 13, there is connected an accordion bellows-like flexible connection 10 between the areas. The structure is matched with the elastic supporting layer 2, so that the angle can be better adjusted, and the comfort of a lying person is facilitated.

More preferably, a non-woven fabric layer 11 is clamped in the abutted seams among the left air bag 14, the middle air bag 14 and the right air bag 14, and the thickness of the non-woven fabric layer 11 is larger than 1 mm. The connecting piece 8 is a pin 12 which is arranged in the perforation of the air bag in a penetrating way, and the pin 12 is I-shaped. The pin 12 is flexible. Above-mentioned structure has simplified the structure of gasbag layer 3, gasbag 14 divides into three district's settings, is provided with ventilative non-woven fabrics between the three districts, is favorable to air current convection from top to bottom very much, also can promote the human body to roll between three districts through the gassing of filling of gasbag 14 simultaneously to the realization prevents the bedsore, alleviates the effect of skin pressure. The three areas adopt wavy matching pins 12, the integrity is better, the connection is flexible and firm, and meanwhile, the connection has good deformation capacity, and gaps can be properly reserved among the air bags 14 in human body overturning, so that ventilation can be further promoted.

The equivalent replacement to this embodiment still falls into the scope of protection of the utility model.
