Definitions
- the invention relates to a pillow with at least two in terms their air pressure adjustable air chambers by a air-impermeable material.
- DE 33 45 291 C2 is already an inflatable seat cushion made of bendable material with several arranged one behind the other and chambers known, which are divided by grooves. The chambers have different heights and communicate with each other.
- a seat cover made of two interconnected, inflatable air chambers is known. There is a retractable valve in the chamber wall with which all chambers can be inflated.
- a chair or armchair is known from DT 23 48 124 A1 , the seat or backrest upholstery of which is composed of a plurality of individually fillable upholstery elements which are connected to one another via lines.
- the lines have closable valves.
- a pillow according to claim serves to solve this problem 1.
- the registration is not a pillow is confined to two air chambers, but two or more air chambers, preferably two to ten, in particular can have three air chambers.
- the foam has a shaping function and means in Trap the back cushion with more volume in the bottom two Chamber a better support of the lordosis area.
- the pillow according to the invention is included additional components or chambers combined, for example with chambers that contain bulk materials such as polystyrene or millet and which are arranged above the air chambers.
- the bulk material has excellent adaptability on body parts.
- Figure 1 shows a pillow in plan view with three air chambers 1, 1 'and 1'', which are made of an air-impermeable material, such as soft PVC and separated by welds 3.
- a ball pump 7 with a drain valve 16 is connected to one of the air chambers (1 ') in order to inflate the air chambers 1, 1', 1 ''.
- the ball pump 7 shown in FIG. 1 is a conventional rubber ball, which sucks in air through an opening and when compressed the ball presses the air into the air chamber 1 ', a The flap valve closes the air intake opening.
- the valves 4 are throttle or shut-off valves with which the flow can be regulated between the air chambers 1, 1 ', 1' '.
- Figure 2 shows the pillow of Figure 1 in a perspective view and with a schematic representation of the filling of the air chambers 1, 1 ', 1''with an open-cell foam 15, which gives the pillow roughly the shape intended for use even when not inflated.
- the foam is easily compressible and has a Shore hardness of 10 to 15.
- Figure 3 shows a modification of the embodiment of Figure 2 with four air chambers 1, 1 ', 1'',1''', wherein two air chambers 1 'and 1''are provided with spot welds 17, the top of the cushion with the bottom connect and which serve to give the affected air chambers 1 ', 1''a certain profile, which has the effect that the pressure area under the ischial bumps is not increased if there is a lot of air in the rear chambers 1 and 1'''.
- the individual air chambers are not all need to have the same height, but in the case of one Pillow or a mattress be profiled differently can. This makes it possible to set the height exactly, the one Wishes user for lying.
- chambers 8 are provided above the air chambers 1, which are shown in FIGS. 4a to c .
- These chambers 8 are expediently filled with loose bulk material, for example polystyrene beads or millet, in order to adapt well to the head contours and thereby achieve an optimal pressure distribution without back pressure.
- the bulk material enables the head to be held exactly in the position which a user feels is optimal.
- Figure 5 shows a fourth embodiment which is similar to that of Figure 1.
- the second air chamber 1 ′′ is provided with a first check valve 14, which allows air to flow into the second air chamber 1 ′′.
- the second air chamber 1 ′′ and the third air chamber 1 ′ are connected to one another by a line 6, in which a three-way valve 4 ′ is arranged as a valve. In a first position of the three-way valve 4 ', an air flow through the line 6 from the second air chamber 1 "into the third air chamber 1' is possible.
- a further line 6 ' connects to the third connection of the three-way valve 4', which in the second air chamber 1 "and in which a second check valve 14 'is arranged.
- the first check valve 14 and the second check valve 14' are continuous in the same direction, so that air drawn into the second air chamber 1" from this chamber also via the Line 6 'and through the second check valve 14' in a second position of the three-way valve 4 'into the third air chamber 1', however, when the three-way valve 4 'is closed in a third position, the air flow through line 6 becomes the third Air chamber 1 'shut off.
- the second check valve 14 'shuts off the line 6' in this direction is not possible because the second check valve 14 'shuts off the line 6' in this direction.
- FIG. 6 shows a fifth exemplary embodiment as a back cushion for a vehicle seat 10, which is embedded between the backrest 12 and the seat cover 13.
- the air chambers 1 are connected to one another again by lines 6.
- a ball pump 7 with a drain valve 16 in turn serves to blow air into the lower air chambers 1 ', 1'', as shown in FIG.
- FIG. 7 shows the fifth exemplary embodiment in a view from the front with an upper air chamber 1, below which two further air chambers 1 'and 1''are arranged.
- the three air chambers 1, 1 ′, 1 ′′ are connected to one another in terms of flow by lines 6, 6 ′′.
- a drain valve 16 and a ball pump 7 are connected to one of the air chambers 1 '.
- an air line 6 leads from each air chamber 1 ′, 1 ′′ to a valve 4, which is led from the valve 4 as a common line 6 to the upper air chamber 1.
- the valve 4 located in the lines 6 is a shut-off valve which, when closed, prevents air from the air chambers 1 'and 1''from flowing upwards into the upper air chamber 1.
- the valve 4 When the valve 4 is open, on the other hand, the air can escape from the air chambers 1 ′ and 1 ′′, as a result of which the driver is gently turned out of his position in the curves by the centrifugal force. This causes a stretching and rotating movement for the driver. If he wants to stay seated straight, he has to tighten his muscles, which are trained and strengthened.
- the valve 4 is expediently adjustable in such a way that the aforementioned effect can be set individually for each driver.
- the back cushion according to FIG. 7 also points towards the valve 4 lead lines each a check valve 14 ', which prevents air from the right lower air chamber 1 'in the lower left air chamber 1 '' can flow.
- This is a Air flow only possible in the direction of the arrows on the lines 6.
- a backflow of air from the upper air chamber 1 takes place via further lines 6 ', one of which is connected to the lower one left and right air chamber 1 '', 1 'leads.
- Combined throttle and check valves 14 '' are provided, that in the direction of the arrows as check valves from the air chamber 1 to the air chambers 1 'and 1' 'are continuous while they air in the opposite direction only slowly as throttles let through.
- the throttling effect of the valves 14 ′′ is so chosen that a the backflow of air from the bottom Air chambers 1 ', 1' 'to the upper air chamber 1 only possible slowly is, for example, in about 2.5 to 3 minutes.
- This is supposed to achieved that the driver when straightening up by muscle tension and pushing his spine out of the air upper air chamber 1 quickly into the lower air chambers 1 ', 1' ' presses, whereby the lower air chambers 1 ', 1' 'the occupied Maintain the desired position until the driver Relaxed muscles.
- the spine sinks again back to the original position (13) of Figure 6 and it there may be renewed muscle tension and air transmission from above done down.
- the point is that the driver is on should not stay in one position for too long. Whenever if he thinks of it or gets the need, he can do the process repeat by tensing and relaxing the back muscles.
- FIG. 7 also shows a further line 6 ′′ which connects the two lower air chambers 1 ′ and 1 ′′ to one another, a valve 4 regulating the flow between these two chambers.
- a further line 6 ′′ which connects the two lower air chambers 1 ′ and 1 ′′ to one another, a valve 4 regulating the flow between these two chambers.
- the fifth embodiment Can have air chambers 1, 1 ', 1' 'with open-pore Foam 15 are filled to a large extent by hand to make redundant.
- the ball pump would be 7 and the drain valve 16 unnecessary and it could be the air intake to the air chambers as in the fourth embodiment Figure 5 take place via a check valve 14.
- FIGS. 8 to 10 show a sixth exemplary embodiment as a mattress, which is expediently intended for storing immobile people and patients.
- the individual air chambers 1 are in turn connected to one another by lines 6, as in the previous exemplary embodiments.
- five pairs of air chambers 1 of the same size are provided, each of which are arranged symmetrically to a longitudinal center line.
- the air chambers are each connected to one another by lines 6, so that an entire longitudinal side allows air to flow between all five chambers on this side.
- the connection of the two sides is made possible by further lines 6 '.
- Solenoid valves are arranged in all lines 6, 6 'and can be controlled by a remote control.
- FIG. 10 also shows pressure sensors 21 which indicate when the body is touching the mattress floor in order to then trigger inflation of the air chambers 1.
- the lines 6 are not as in the Figures shown must be external to the pillow; they can also be arranged internally, if only ensured is that the valves 4 can be regulated from the outside. For this purpose it is possible to either put the valves 4 in to be placed on a side seam or close under the cushion surface to be arranged if the thin skin of the pillow allows Feel and adjust valves from the outside.
- valves 4 shut-off valves, Regulating valves or throttle valves can be around the Set pressure in the various air chambers.
