The tension-type cavity (1) comprises a liner (1-1), a tension layer (1-2) and a support (1-3), wherein the tension layer (1-2) and the support (1-3) constitute a pull-support structure; the liner (1-1) is disposed inside the pull-support structure; and the tension layer (1-2) is in flexible contact with the liner (1-1) to form a working face (1-5), and the working face (1-5) restricts bulging of the liner (1-1), thereby realizing external flexible shaping of the liner (1-1). The liner (1-1) has a simplified construction, and is not subjected to stress concentration, such that the safety and the service life of the liner are greatly improved; and the liner (1-1) uses an upper portion or front portion heating manner, thereby realizing instantaneous heating and temperature control. The tension-type cavity (1) is in communication with an external flexible bag to constitute the connected cavity, and the seat and the bedding comprise the connected cavity. The connected cavity structure realizes free migration of an internal liquid, greatly reduces the pressure in the liner (1-1), buffers the impact of an external force on the liner (1-1), and facilitates the protection of the liner (1-1). Moreover, a water level difference in the connected cavity counteracts the liner (1-1) to generate uniform and gentle hydroelasticity, thereby improving the comfort of sitting and lying.

As shown in Fig. 1, the tension layer 1-2 of the tensioning structure has continuous tension in the cross section shown in the figure, and the tension layer 1-2 expands laterally under the continuous tension, and is tensioned in the lateral direction. The tension layer 1-2 has no tensile force or only a small tensile force in the direction perpendicular to the cross-section, as shown in FIG. 1, the tensile structure composed of the tension layer 1-2 and the supporting body 1-3 has a single Pull direction.

The tension layer 1-2 of the tensioning structure stretches along the tensioning direction and is in a tensioned state. The tension layer 1-2 defines the bulging of the liner 1-1 at the soft setting surface

The soft setting surface includes a working surface 1-5.

As shown in FIG. 1, the tension cavity lies flat when in use, and the upper soft shaping surface directly supports the user, and this part of the soft shaping surface constitutes the working surface 1-5 of the tension cavity.

Or, as shown in FIG. 3, the tension cavity is placed upright during use, and the soft shaping surface of the front part directly provides a leaning support for the user, and this part of the soft shaping surface constitutes the working surface 1-5 of the tension cavity .

The working surface 1-5 restricts the expansion of the inner liner 1-1 when it is filled with water. When the working surface 1-5 is subjected to external pressure, the pressured part is depressed, and the inner liner 1-1 that presses the flexible contact with it is depressed .

The brace structure body forms a loop on the cross section along the brace direction and perpendicular to the working surface 1-5, surrounding the liner 1-1, the support body 1-3 includes a planar body extending in two dimensions and / or a three-dimensional direction The curved surface body defines the surface shape of the corresponding working surface 1-5 as a flat surface and / or a curved surface.

Preferably, the quadrilateral frame is a four-bar linkage, and the distance between the two sides can be adjusted by changing the relative position between the bars.

By adjusting the distance between the opposite sides of the quadrilateral frame, the tension value of the polyester cloth cover is adjusted.

Optionally, the tension value of the polyester fabric cover is between [1 to 200] kgf, preferably [10 to 60] kgf, and [20 to 40] kgf is the best.

The total tension of the upper and lower layers of the polyester fabric cover is twice the value of the above tension.

Preferably, a heating pad is included.

Preferably, a heating pad 4 is placed on the working surface 1-5 as shown in FIG. 1 or in front of the working surface 1-5 as shown in FIG. 3, which is heated on or in front of the liner 1-1. The method realizes instant heating, which changes the traditional bottom or internal heating method. It is convenient to use, saves energy, and has obvious advantages.

Filling the cavity with water from the interface 1-4, the inner liner 1-1 expands, the expansion force pushes the upper layer of the inner liner 1-1 to expand outward, and the working surface 1-5 of the tension layer 1-2 expands outward The component of the downward tension gradually increases, and finally reaches the balance of the expansion force of the inner liner 1-1, the upper layer of the inner liner 1-1 stops bulging outward, and the working surface 1-5 realizes the inner liner 1 The setting of -1 is because the working surface 1-5 is a flexible surface made of soft materials, so the setting is soft setting.

The greater the tensioning force on the tensioning layer 1-2, the stronger the limiting effect on the inner liner 1-1, the smaller the bulging amplitude of the tensioning cavity, and the soft shaping surface on the working surface 1-5 The flatter.

The external soft-setting structure of the tension cavity replaces the traditional rib-forming structure of the traditional water-filled or inflatable bag, and the styling of the bag can be achieved without the need for ribs. For the non-reinforced inner liner 1-1, there is no hot-melt link between the reinforcement and the bile body, which avoids the brittle material from melting and becoming brittle, and there is no stress concentration in it, which greatly improves its safety and extends its Average service life; for the liner 1-1 with ribs, because the external soft styling structure bears the expansion force when it bulges outwards, the internal ribs receive little or no tension, so they are pulled The stress concentration at the fusion edge of tendon and liner 1-1 is greatly reduced or even zero, which also improves the safety of liner 1-1.

Example 2

In this embodiment, as shown in FIG. 4, the tension chamber 1 communicates with the fluid containing device 2 to form a continuous chamber.

The connecting cavity is filled with water through the water nozzle 3, the liner 1-1 is filled with water, and the fluid holding device 2 is filled with a small amount of water. It is full of water, so that the water in the cavity can freely move between the inner tank 1-1 and the fluid containing device 2.

When the user is seated or lying down, the inner bladder 1-1 is compressed, and part of the water in it moves to the fluid holding device 2 in a high position, the tension chamber 1 "makes" space to accommodate and fit the body curve , Increase the contact area between the body and the cushion, reduce the contact pressure per unit area, the water level difference between the inner bladder 1-1 and the fluid containing device 2 makes the tension chamber 1 always maintain soft water elastic support, improve the comfort of sitting and lying degree.

When the user leaves the connected chamber, the external pressure on the inner bladder 1-1 disappears, and part of the water in the fluid containing device 2 is replenished to the inner bladder 1-1 under the action of the water level difference, and the inner bladder 1-1 is restored to Full water.

Compared with the ordinary lacing water-filled bag filled with water and completely closed, the water in the tension chamber 1 can move freely inside the connecting chamber, which greatly reduces the inner pressure of the liner and buffers the impact of external forces on the liner, which is beneficial to It protects the inner tank, improves the safety and average service life of the inner tank 1-1, overcomes the shortcomings of repeated conduction vibration of water in the closed container, and avoids the uncomfortable feeling caused by the unbuffered strong support.
