Description

 Anatomical cushion

OBJECT OF THE INVENTION

The present invention relates to an anatomical cushion of the employees usually used to achieve either the rest, or the best accommodation during work activities, driving a car, etc.

BACKGROUND OF THE INVENTION

Normally, anatomical cushions are used on the seats, whether chairs, armchairs, sidewalks, stools, car seats, etc., to achieve a more comfortable and comfortable support in the daily activities that we develop sitting for long periods of time, either at work, in the car, or at home.

The known anatomical cushions comprise two foam bases and an inner layer of a so-called therapeutic gel whose composition is water, glycerin and sodium carboxymethyl cellulose.

These cushions are located between the seat and the buttocks of the user, and although they attenuate to a certain degree the hardness of the surfaces where they rest, they do not achieve complete comfort, especially when the user has spent a lot of time sitting.

Therefore, it is required to design an anatomical cushion that truly provides the user with great comfort support for the long time they remain seated.

DESCRIPTION OF THE INVENTION

In view of the foregoing, the present invention relates to an anatomical cushion.

The cushion comprises an outer sheath that encloses a filling with a base layer of foam. Additionally, the filling comprises an elastic gel core disposed between the base layer and a viscoelastic foam support layer.

On the other hand, the upper face of the support layer is formed by an irregular surface with a wavy profile with ridges and valleys arranged alternately throughout the extension of said upper face of the support layer.

The cushion adapts instantly to the shape of the user's buttocks, leading to a considerable reduction in the maximum pressure values by immersion of the support areas in the viscoelastic material. Likewise, the elastic gel promotes additional cushioning while keeping the cushion cool in summer and warm in winter.

On the other hand, the ridges practiced on the surface of the support layer act as massage means that stimulate blood circulation in the body while the user remains seated on the cushion.

Then, it is possible to have a cushion that provides a support of great comfort, allowing the user to sit comfortably for a long time.

DESCRIPTION OF THE FIGURES

The present specification is complemented, with a set of figures, illustrative of the preferred example and never limiting the invention. Figure 1 represents a cross-sectional view of the cushion.

DETAILED EXHIBITION OF THE INVENTION

In view of the foregoing, the present invention relates to an anatomical cushion.

As Figure 1 shows, the cushion comprises an outer sheath (1) that encloses a padding (2) with a base layer (2.1) of foam.

Additionally, the filling (2) comprises an elastic gel core (2.2) disposed between the base layer (2.1) and a support layer (2.3) of visco-elastic foam.

As shown in figures 1 and 2, the upper face (2.31) of the support layer (2) is formed by an irregular surface with a wavy profile with ridges (2,311) and valleys (2,312) arranged alternately throughout the entire extension of the upper face (2.31) of the support layer (2.3). In other words, the ridges (2,311) form a kind of visco-elastic foam mounds separated by valleys (2,312) in the form of holes arranged alternately throughout the entire length of the upper face (2.31) of the support layer (2).

Preferably, the ridges (2,311) have a height of 5 mm.

For its part, the elastic gel core (2.2) can be liquid, as shown in Figure 3, preferably contained in a plastic bag (2.21). For example, the elastic gel core (2.2) can be constituted of liquid polyurethane or other liquid substance that facilitates cushioning while keeping the cushion cool in summer and warm in winter.

However, as Figures 4, 5 and 6 show, in other preferred embodiments, the elastic gel core (2.2) is solid. For example, solid polyurethane, rubber, PVC, or other material that facilitates cushioning while keeping the cushion cool in summer and warm in winter.

Particularly, as shown in Figure 4, the solid elastic gel core (2.2) can be formed by a honeycomb-shaped structure (2.22). However, it could be formed by a reticulated structure of rings (2.23) or spheres (2.24), seen in Figures 5 and 6 respectively, among other structural configurations.

On the other hand, the base layer (2.1), like the support layer (2), can be formed of viscoelastic foam.

Likewise, it is preferred that the base layer (2.1), the core (2.2) and the support layer (2.3) be individually shaped and subsequently glued together to form the filling (2).

Claims (4)
