Abstract

Seat incorporating ischial support characterized by comprising a gluteal-femoral support component constituted by a curved and inclined front part, a horizontal central part with two subischonic hollows, and a rear part having a cylindrical shape (13) with a protuberance optional functionality similar to that of the mercies of the seats of the choirs in the old cathedrals (14), being able to turn the whole piece vertically around a turning and fixing device (9), which transforms the chair-type seat (figure 1) on an ischial support (figure 2), as described above.

State of the art

At present we do not know the existence of a movable seat that allows the user to adopt the posture classic seated and, in addition, the resting position based on the Ischiatic support concept. The chairs found in the market for sedentary work does not incorporate the possibility of ischial support. And vice versa.

Explanation

Seat that incorporates ischial support that it comprises related components in such a way that they integrate a single general inventive concept: that of helping the user to adopt healthily two different resting positions without change seats

The seat that incorporates ischial support is a reposing object intended to relieve tiredness and improve health of people who work for long periods of time in static postures. In this type of activity, the impossibility of a change in posture is a risk factor that has consequences in the health of the user, particularly as regards fatigue excessive, varicose veins and musculoskeletal system both the back and the lower extremities. If he subject performs displacement of loads -as is the case of collection boxes in supermarkets or in some production chains or packaging - the trapezius and dorsal muscles are more affected if the subject adopts a classical sedentary posture that if he works standing or in the posture induced by an ischial support, resting the trunk in a support that facilitates the change of orientation of the body of the seated, turning the seat around an axis.

This stand up semi-standing It is convenient for public activities because it maintains the head of the worker at a level similar to that of the client; it is about In addition, an activating posture, less passive than the seated one classic.

The seat that incorporates ischial support consists from:

- a central support (3) that rests on a plurality of horizontal spokes (6) substantially close to the ground, which can rest respectively on two wheels (7) and three studs; This support is height adjustable by means of a gas piston (4) that is operated through a lever for this purpose (5).

- a special sacro-gluteal-femoral support component that induces an obtuse coxo-femoral angle at the seat (fig 1) and can be rotated around a horizontal axis (9) to convert the seat into a support device ischial (fig 2). This seat piece consists of a hard core and a slightly elastic soft covering.

The front part of the support component sacral-gluteal-femoral -or seat- (10) has a curved shape and a slope forward and towards down.

The central part (11) has the leading edge curved, and in its hard soul optionally two holes can be made symmetrically arranged and whose distance from each other is noticeably equal to that between the horizontal projection of the User ischiae (12). About these holes have been made gaps in the soft cover of the seat, which are filled of more elastic material than the rest of the piece. Optionally, the thickness of the material can be reduced soft seat covering in this area instead of filling those gaps

The back of the seat has a shape cylindrical (13) with an optional functionality bump similar to that of the mercies of the choir seats in the old cathedrals (14). This rear seat acts as ischial support in the semi-standing posture (2) and as sacred support in the sitting posture (1).

- a component for backrest , which preferably requests the spinous processes of the spine at the lumbo-dorsal level and the adjacent paravertebral musculature (15) in the sitting position (figure 1), and which requests the sacral region in the semi-de position foot (figure 2)

With the mechanisms described, the seat that incorporates ischial support allows the user:

- raise and lower the seat and backrest, by operating the gas piston lever (5)

- rotate the seat around the horizontal axis (9) to convert the device into an ischial support, unlocking one of the fixing positions and blocking the other. This operation can be performed with any of the existing mechanisms in the market.

No market object currently allows duality of body supports or ease of posture change which offers the seat that incorporates ischial support described here, which also allows easy transfer of the device by tilting it around the two wheels of the base, and the stability of the user when the set is supported on three studs that prevent the rolling

Description of the drawings

Figure 1 shows a seat that incorporates ischial support seen sideways, showing a scheme postural user sitting (1).

Figure 2 shows the same seat as incorporates ischial support seen in profile showing a scheme user postural in semi-standing position (2).

Figure 3 schematizes the shape of the profile side of the seat incorporating ischial support prepared for induce a sitting posture.

Figure 4 schematizes the shape of the profile side of the seat incorporating ischial support prepared for induce a semi-standing posture.

Figures 5 and 6 show a view postero-inferior of the device in its two possibilities.

Figures 7 and 8 show a view antero-superior of the device in its two possibilities.

Detailed statement of at least one embodiment of the invention

The seat that incorporates ischial support can be constituted as any element of market chairs, but finished with aseptic materials and able to resist even Antiseptic treatments for use in laboratories. To that end, the outer surface of the soft seat coverings and Backrest, it is made of polyurethane, smooth and has no wrinkles or gaps, and the hard parts (structure, buttons, levers, arm supports and pistons) are made of stainless steel.

The pistons (4) will be those found in the market, with buttons and levers (5), stainless steel. The supporting column of the seat lift piston (3), made of steel stainless.

The soul of the seat, made of stainless steel, will go subject to the turning and fixing mechanism of the two positions of the seat (9).

The support profile of the backrest (16) is stainless steel.

The five-spoke base is made of steel stainless.

Indication of the manner in which the invention is susceptible to industrial application, unless it is derived in a manner evident from the nature of the invention or from the explanation of the same

The seat that incorporates ischial support is a seating element and enjoy the application features industrial that can have a work chair: it can be manufactured in Any factory in the sillera industry.
