Description

SEAT / BED SENSIBLE DESCRIPTION OF THE INVENTION The present invention relates to seats, for example without limitation; motorized vehicle seat, lounge seat, adjustable seats or beds for medical and dental examination, office seat, child safety seat, waiting room seat, play chairs and hospital bed. More particularly, the invention provides a modular system for providing a load-sensitive seat / bed that provides a user with improved comfort and safety when placed on the seat or bed.

For simplicity, the term "seat" as used herein should be interpreted to include the wide variety of seats and beds indicated above.

Modular seats are known, for example in the automotive industry. Predominantly the automotive seats are built in individual sections, these are a structure element and a cushion element. It is clear that the structure and cushion elements in the prior art are not considered integral with each other. Numerous examples of the prior art can be used to illustrate such. Jackson (US2006125304) illustrates a cushion element that is capable of being incorporated into a structural element and as such Jackson does not provide an integral solution.

REF: 235832 Steele et al. (WO03018353) shows a structure element with a focus on the ability to bend. Steele et al. Illustrates that the seat structure has been considered separate from the cushion element and in terms of non-integration is similar to Jackson. This philosophy is again demonstrated with SIEGEL et al. (DE10358720) where the focus is again on a folding structure element as opposed to an integrated solution which also considers a cushion element as an integral feature to form a complete seat.

The new integration illustrated by the prior art typically results in excessive seat dimensions where the general seat occupies a large amount of space in a vehicle since the two elements are considered separately. This is further shown by Jackson where the traditional approach to structures independently of comfort results in an additional unit requirement to assist the user in seat adjustment.

Particularly in the automotive sector, the requirement of thin and light seat that is also comfortable for the user is increasingly of paramount importance. For example, the dimensions of the seat dictate the cabin space and consequently the permissible shape, space of occupancy, size and weight of the vehicle and in that way the aerodynamics and the total fuel efficiency of the vehicle.

The present invention seeks to address this problem by providing an integrated seat design wherein the structure element and user comfort are considered and resolved in a compact and light individual construction.

The present invention further seeks to provide modular seating sections that are actively load sensitive and that can be represented in a compact and lightweight construction.

In accordance with the present invention there is provided a support section for a seat comprising a load responsive structure completely or partially encompassed in amorphous upholstery, the structure comprises multiple independently operable load sensitive subsystems which collectively allow the support section to respond and react to local load areas accordingly to provide superior support and comfort to the seat occupant.

A foam layer may comprise a foam which is a high density foam or a foam which is flame retardant.

Coated layers can be pressurized. The optionally contained fluid is at least partially gaseous and can, for example, comprise oxygen.

Desirably, the cover layer is configured to have a low friction surface on the surface that interconnects with the encompassed layers.

One or more of the subsystems desirably comprises a position adjustment mechanism comprising a motor arranged to drive a drive screw in rotation about the central axis of the drive screw; a toothed motor that is intertwined with the drive screw, rotation of the drive screw that causes linear movement of the toothed motor; the toothed motor independently interlaced with a first gear, linear movement of the toothed motor causing rotation of the first gear wheel a second gear wheel interlaced with the first gear, rotation of the first gear in a first direction causing rotation of the gear second cogwheel in an opposite direction; the second toothed wheel that is interlocked with a toothed rack, the toothed rack arranged in parallel alignment with the toothed motor and rotatably mounted to allow rotational movement on the linear axis of the toothed rack, rotation of the second toothed wheel resulting in linear displacement of the first and second gear wheels and toothed motor along the length of the toothed rack.

The mechanism optionally further includes a third toothed wheel which intertwines with the toothed rack and while free-standing to rotate in position relative to the second toothed wheel. The three sprockets are desirably contained in the housing, the housing adapted not to restrict the linear movement of the sprocket system relative to the toothed rack.

Optionally the rotation of the toothed rack is counteracted by a deflection mechanism.

Conveniently, two mechanisms of the invention can be connected by means of a load sensitive connection that transmits changes in the load applied to one or both mechanisms in order to adjust the linear position of the gears and the toothed motor.

Desirably the load-sensitive connection is., In response to asymmetric loading to adjust the position of each position adjustment mechanism independently of the other. The load sensitive connection conveniently comprises an elastic deformable material. In specific embodiments, the load-sensitive connection may comprise at least in part a plate or a bar of flexible material that it incorporates. a plurality of cut channels that under load can cause closure under compression or opening under tension. Optionally the connection in response to load comprises at least part of a spring.

In a particularly useful application, the linked pair of mechanism is represented in a support structure for a seat, the support structure comprises a pair of support members disposed substantially in parallel with the toothed rack and the cross-plate members which extend between the support members, the support members and the cross plate members together comprise the mechanisms in pair. Desirably, the cross plate members are composed at least in part of an elastically deformable material.

Preferably, the support members are fixed in position and the cross plates are flexibly attached to the support members. The flexible connection is desirably an elastically deformable connection that allows the plate members to return to a neutral position with respect to the support members when the apparatus is not under load.

In a preferred embodiment, the cross plate members are encompassed in a flexible cover, the cover has a low friction surface that can interact with the cross plate members. Desirably, the cushioned upholstery layer encompasses the flexible layer.

The support structure is usefully employed as a backrest of a car seat.

The backrest is conveniently attached to a seat base by at least one gear mechanism configured to allow adjustment of the angle between the plane of the backrest and the plane of the seat base. In one embodiment, the gear mechanism comprises an actuator configured to drive a first bevel gear, the first bevel gear being interlocked with a second bevel gear oriented in a substantially orthogonal plane of the first bevel gear; the second bevel gear operates a drive screw that carries a toothed motor nut, the toothed motor nut configured to move linearly along the drive screw as the second bevel gear rotates; a third gear that is intertwined with the teeth of the toothed motor nut and operable to tilt the drive screw relative to an output shaft rotatably mounted on the seat base whereby it tilts the backrest of the seat relative to the base of the seat.

In a preferred embodiment, the third gear is joined to the output shaft by means of an additional intermeshing chain, the last in gear in the chain is fixedly mounted to the output shaft.

The connection means between the backrest and seat base portions is not essential to the invention and can comprise any of a permanently fixed, detachably fixed and / or movable connection. In the presently described embodiment, the seat and backrest are movably connected, for example connected on an axis, whereby the backrest can be moved relative to the seat in a rotatable manner allowing the backrest to tilt. The rotational movement of the backrest is facilitated by at least one rotary actuator which can be located widely within the seat or the backrest, alternatively the actuator can be located externally.

The or each rotary actuator can be configured to allow the backrest to rotate on at least one axis. The backrest and / or the seat optionally further include at least one linear actuator. The or each linear actuator can be used to increase or decrease the linear separation between the backrest and the seat, for example (but without limitation) by moving the seat forward or backward independently of the backrest, or the backrest up and down regardless of the seat portion. In this way, the modular integrated seat can be configured to allow both the rotary and linear movement of the seat relative to the backrest and / or the backrest relative to the seat.

The linear and rotary actuators provided in the seat and / or the backrest can be arranged to operate simultaneously allowing the backrest and / or the seat to move in a combination of linear and / or rotational movement with respect to each other. Any combination of linear and rotary actuator may be incorporated into or associated with either or both of the backrest and the seat.

In addition, the linear actuator having a first linear axis can be located generally towards one side of the backrest or the seat and another having a second linear axis generally toward the opposite side of the backrest or seat, each linear actuator can operate to cause linear movement along its own axis independently of the other. The linear actuators can be mounted on an axis at one or both ends. With this arrangement, the backrest or seat is generally able to move along the first or second axes depending on which linear actuator is operating and / or the relative speeds of each linear actuator.

The integrated seat can be connected with a supporting structure, for example without limitation a vehicle body or a support structure for a seat. The nature of the connection is not essential to the invention and can comprise any of a permanently fixed, detachably fixed and / or mobile connection. The connection can be made directly between either or both of the backrest and seat portion. The integrated seat may also have associated with it at least an operable operating mechanism to allow the integrated seat to move linearly and / or rotationally. Again, the nature of the connection of the operating mechanism to the seat is not essential to the invention and may comprise any of a permanently fixed, detachably fixed and / or mobile connection.

The operating mechanism can be permanently fixed, detachably fixed and / or movably connected to at least one support structure, for example but without limitation a vehicle body or structure or assembly. The integrated seat is capable of joining both an appropriate operating mechanism and at least one support structure.

Suitable operating mechanisms are known in the prior art and it is within the ability of those skilled in the art to adapt these for use in accordance with the invention. Several examples of operational mechanisms' which provide singular movements or combinations of movement are available in the prior art. A simple and useful example (without limitation) of the automotive industry are slides that are commonly used to move a vehicle seat linearly forward and backward. Mechanisms that facilitate the inclination of a backrest with relation to the seat or the seat relative to a base are also known; the position of a lumbar support portion of a backrest and the up and down movement of both the backrests and the seating portions.

The seat is desirably provided with at least one or more operating mechanisms configured to allow the integrated seat and / or the backrest and / or the seat portion to move in a wide variety of dimensions some or all of which are selected from; linearly from front to back; linearly from top to bottom; tilt and roll rotating (to allow tilting from side to side or from front to back) and / or deflection. The configuration can be arranged to allow any combination of these movements to be performed simultaneously or independently.

The operating mechanism (s) may be conveniently represented as a connection between the seat and back portions allowing the singular movements or the combination of them to be moved to one or more of the seat back portion allowing the portions to be repositioned in relation to each other as well as the relocation of the complete integrated seat in one setting. The seat and / or backrest portion can optionally be decoupled from the operating mechanism to allow independent movement of the seat or backrest portion.

Optionally, the backrest is mounted directly to a support structure by means of an operating mechanism and is capable of being subjected to rotary and / or linear movement. Therefore, the backrest is able to join the support structure with the seat then joined the backrest. Alternatively, the seat is capable of joining the support structure. In another option, both the seat and the backrest are directly linked to the support structure.

The support structure can represent at least one actuator that can be rotatable, linear or a combination of the two. A rotary actuator desirably includes an output shaft capable of forming completely or in part a connecting element to which the seat portion and / or the integrated seat can be attached. The connection can be anything from (without limitation) a fixed connection, a rotary connection, a slidable connection and / or a detachable connection. The output shaft can, optionally, provide the joining elements, the first that can be attached to the seat and the second to the backrest.

Each of multiple support structures may include one or more actuator is that they are linear or rotary in any combination. Desirably, rotary actuators are arranged coaxially and share an axis of rotation with the connecting elements. In this arrangement, when at least one rotary actuator widely within a support structure rotates then the backrest and / or the seat rotate.

When a linear actuator is also incorporated with the support structure then the linear actuator and the rotary actuator can operate simultaneously or independently. When two or more support structures are present with each member having at least one linear actuator, it is preferred that the linear actuator in each member can act at different speeds and / or at different times. Typically, but not limited to this, the linear actuators are capable of representing a suitable pivot point at each end. Pivot points are well known in the prior art and include (without limitation) a pink-type bar end union or other multi-axis couplings.

Desirably the seat is configured to have at least one rotary actuator completely or partially represented in the seat portion of at least one linear actuator. completely or partially represented in the backup portion.

The output shafts of the rotary actuators in the seat or back portion may conveniently be arranged coaxially with output shafts of rotating actuators in the other of the backrest or seat portion. An output shaft of a rotary actuator associated with the seat is optionally attached to the first linkage member of the output shaft of a rotary actuator associated with the support structure; a rotary actuator in the backrest can be attached to the second joint member of the output shaft of the rotary actuator associated with the support structure. As previously described, all connections are optionally permanently fixed, detachably fixed and / or mobconnections.

In the arrangement described above, a rotary actuator in the seat and / or the backrest can be configured to rotate counter to movement to rotate in the same direction to the movement of the rotary input of a rotary actuator of at least one support structure. This allows configurations where; the backrest and seat can rotate independently of each other and the input of the rotary actuator to the support structure; or can move in motion combined with the input of the rotary actuator.

The ability of the seat and / or the backrest to rotate in an opposite manner allows the seat and / or backrest to rotate independently and allows each to maintain a position regardless of the rotation of the rotating output shaft or the axes of the rotary actuator of the structure of support .

In another alternative, a linear actuator may be completely or partially represented in a support structure, a seat portion and / or a backrest portion. The multiple linear actuators associated with the seat, backrest and support structures may be configured to extend and retract independently, together, or in groups. For example, the sections of the integrated seat can comprise multiple linear actuators that can work in conjunction with a group, but independently of other actuators or groups of actuators in different sections.

Optionally, the integrated seat can incorporate one or more airbags. The air bag (s) may optionally be incorporated in any one or any combination of the back, seat or support structure.

As mentioned, the back and / or seat portion may comprise multiple sections for example (but without limitation), these sections may include a headrest, a lumbar support, a butt support and a thigh support.

The previously described joining elements can comprise a variety of different sizes and / or lengths of configurations. Very conveniently (but without limitation) collectively comprise a variety of different diameters and different lengths.

The different lengths and diameters allow the seat and backrest to join the elements. This arrangement of joining the seat and / or backrest portions to the output shaft achieves rotational movement independent of the portions against or congruent with the rotation of the output shaft and the element. Therefore, at least one output shaft is capable of rotating, through the rotation of the transmission path that includes but is not limited to at least one drive screw and at least one gear or toothed shaft.

The use of a drive screw allows the rotary actuator to self-lock so that it retains a position without the requirement of continuous power. It will also be appreciated that the housing and / or at least one gear, an axle, a mount is capable of being incorporated and allows interaction with at least one stored energy system. The stored energy system could comprise any of a number of configurations, for example (but without limitation) includes springs.

The pending international patent application of Applicant PCT number 2010/000250 illustrates the use of springs to the stored energy system that can be incorporated into seats made in accordance with the present invention. As an example, the rotary actuator by incorporating at least one mechanical spring or other type whereby movement in the first direction allows the energy to be recovered and stored for use (deployment) in a second direction. The arrangement can be configured to allow recovery, storage and deployment at any point or a desired pattern of points in the movement cycle of the rotary actuator. Such an arrangement is allowed to self-block as well as store energy from one direction so that that energy is deployed in the opposite direction.

A support section can be attached to another body, the connection is configured to allow movement relative to the body in any one or more three linear orthogonal dimensions, a first dimension is parallel to the body plane. In addition, a support section can be joined to another body, the connection is configured to allow rotational movement relative to the body on one or more of three orthogonal axes, a first axis is parallel to the body plane.

Conveniently, the body is another support section optionally associated with a different seating section. Alternatively, the body is an independent support structure of a seat or backrest in which the support section is represented; for example but without limitation; the support structure is selected from; a vehicle body, a mounting structure or a seat portion that does not represent a support section as previously described.

The connection conveniently comprises at least one rotary actuator configured to allow adjustment of the angle between the plane of the backrest and the seat base and the plane of the body. Examples of suitable rotary actuators are further described herein.

An example of a rotary actuator comprises a gearbox having an actuator configured to drive a first bevel gear, the first bevel gear being interlocked with a second bevel gear oriented in a plane substantially orthogonal to that of the first bevel gear; the second gear operates a drive screw that transports a toothed motor nut, the toothed motor nut configured to move linearly along the drive screw as the second bevel gear rotates; a third gear that is interlocked with the teeth of the toothed motor nut and operable to tilt the drive screw relative to an output shaft rotatably mounted on the body. The third gear can conveniently be connected to the output shaft by means of an additional interconnection gear chain, the last gear in the chain is fixedly mounted to the output shaft.

In a further example, the output shaft of the rotary actuator serves as part of the driving mechanism for the linear position adjustment mechanism already described.

The rotary actuator optionally incorporates an elastic means which serves to store energy when the rotary actuator rotates in a first section and to release energy when the rotary actuator rotates in a direction opposite to the first direction. Without limitation, the means may comprise a mechanical spring.

A linear actuator to move the section optionally is composed; drive means for driving a drive column in a rotational movement, a transition screw configured to rotate as the drive column rotates, an axially aligned piston rod that intertwines with the drive screw thread and means for retaining the piston rod in a fixed rotary position with respect to the axis of the drive screw whereby the axial rotation of one of the drive screw and the piston rod relative to the other of the drive rod and the piston rod results in adjustment of the relative positions of the piston rod and drive screw along the axis of the drive screw. The means for retaining the piston rod in the fixed position can conveniently comprise at least one longitudinal recess in the driving column into which slidably engage at least one protrusion extending circumferentially of the piston.

The piston rod is desirable but not essentially slidably mounted through a first gear driven by a motor, the first gear being interlocked with a second gear fixed to the drive column whereby with the drive of the motor, the Impeller column rotate and rotate the drive screw. In another useful but not essential option, the linear actuator includes a mounting opening that can be rotatably mounted on an axle. The mounting opening can be mounted conveniently on the output shaft of a rotary actuator.

Preferably, the structure incorporates one or more openings through which air conditioning can be supplied to the seat from within the seat. Desirably the seat also incorporates a manifold and. duct that connects with the opening, the duct that also connects with an air conditioning system located externally of the seat, for example inside a body of the automobile where the seat is mounted. Most desirably, multiple openings are provided and a branched duct system that supplies air conditioning to each. one of the multiple openings. In addition, one or more fans may be provided within the duct to facilitate removal and circulation of the air conditioner to the seat.

The structure may comprise support means connected by one or more cross plate members, the connection between the cross plate member and the support member is composed of a neck portion of the cross plate member surrounding a support member post , the post and the neck are rotatably connected by means of a bearing. Desirably, the neck portion includes a low friction cover on its outer surface. Also desirably the post is hollow allowing the circulation of fluids and / or air conditioning through the seat.

Optionally the hollow post also includes ribs to reinforce the support structure.

A seat or a seat section in accordance with the invention desirably include adjustment means for adjusting the stiffness of the section and / or the range of load within which the section responds.

A seat base embodying the invention optionally has a structure comprising support members connected by one or more cross plate members, upholstery is provided on an outer face surface of the cross plate member or members and a cushion plate is elastically deflected against the inner face surface of the cross plate member (s). The seat base optionally will also include at least one mechanism for adjusting the height and / or orientation of the seat base, the mechanism is encompassed by the structure and a transfer table for transferring loads applied by the mechanism to the cross-plate member through the damper plate. Desirably the mechanism is a double-purpose lifting and tilting mechanism.

Conveniently, the mechanism may comprise a lifting cam.

The damping plate may conveniently comprise an arcuate section of elastically deformable material anchored to the support members.

A seat comprising one or more support sections may further include a locking mechanism for locking one or more seat components in position.

In a preferred embodiment, the block comprises; a drive screw mounted on bearings, the drive screw driven by an actuator and interlocked with a toothed motor rack, the toothed motor rack is transported on a locking bolt which is caused by the drive of the drive screw it moves axially along the drive screw shaft whereby it engages or decouples with a component to be locked or unlocked.

In an alternative desirable embodiment, the block comprises; a drive screw mounted on bearings, the drive screw driven by an actuator and interlocked with a screw threaded neck, the neck carries multiple locking bolts that with the drive of the drive screw are caused to move axially length of the transmission screw shaft whereby they are coupled or uncoupled with one or more components to be locked or unlocked.

The locking mechanism can be conveniently used to lock the backrest to the seat base.

By the proper choice of material and adjustment of the parameters of the connection and drive components described a seat constructed of the modular seat support sections as described and interconnected as described can be configured to provide optimum comfort and support to the user as well as increased protection in reaction to a sudden and unexpected change in load conditions on the seat, incurred, for example, when a vehicle in which the seat is used is involved in a crash.

In addition, the integrated seat construction as described in accordance with the invention allows the realization of an ultrathin seat which in turn generates increased cabin space and reduced vehicle weight which in turn allows more flexibility in optimizing the exterior design of a vehicle as well as facilitating a general reduction in the overall size of the vehicles if required.

The benefits of this added flexibility to the vehicle design allows a vehicle to be optimized not only to reduce the pollution generated by the vehicle (and consequential environmental damage) when the vehicle is used, but also the environmental pollution that would otherwise be generated during the manufacture and distribution on an industrial scale of vehicles compared to previously known vehicle designs.

Now some embodiments of the invention will be described by way of example only with reference to the appended figures, wherein: Figure 1 shows a flat view of the seat and backrest with the back folded flat; Figure 2 shows a side view of a typically rotary actuator; Figure 3 shows a side view of a rotary actuator adapted for linear movement; Figure 4 shows a side view of a linear actuator Figure 5 shows a side view of a double actuated member with linear actuator; Figure 6 shows a front view of a foldable backrest; Figure 7 shows a front view of a backrest with ventilation, heating and cooling; Figure 8A shows a top view of the backrest; Figure 8B shows an approach to the back-up structure and comfort systems; Figure 9A; shows a front view of a seat base in accordance with the invention; Figure 9B; shows the seat base of Figure 9A in more detail; Figure 10A; shows a first embodiment of a locking mechanism for use in the invention; Figure 10B; shows a second embodiment of a locking mechanism for use in the invention; Figure 11; shows a plan view of the seat base of Figures 9A and 9B in section; Figure 12; shows a plan view of the seat base of Figures 9A and 9B.

Figure 1 illustrates an embodiment of an integrated seat 1 consisting of a seat portion 3 and a backrest portion 2. The seat 3 and backrest portions 2 are modular and can be used independently of one another in combination with other seating configurations. of seat or backrest. Figure 'shows seat 3 and backrest 2 in a flat view with the backrest reclined relative to seat 3.

Figure 2 illustrates a rotary actuator 6, however it is capable of using any suitable type of rotary actuator. This particular rotary actuator format is taken from the international patent application pending resolution of Applicant number PCT GB2010 / 000250. The rotary actuator 6 consists of a housing 36 that can house the interior parts of the rotary actuator. The housing contains an actuator 8 attached to a gear 10 and typically but not limited to the actuator 8 is an electric motor but could also be a manually driven motor. The gear 10 in this housing (but without limitation) is a bevel gear that is interlocked with an additional bevel gear 12 which in turn is attached to the drive screw 34 so that the rotation of the actuator 8 results in the rotation of the gears 10. and 12 and the transmission screw 34. The transmission screw can be mounted on at least one bearing 26.

The actuator 8 is capable of being at any angle and it is desirable that it be attached directly to the drive screw 34 without the requirement of any of the gears. Alternatively (and as shown) the actuator 8 can be connected to the transmission screw 34 by at least one gear. Where more than one gear is used, they are capable of being of different sizes. The gear 12 is also capable of being integrated with the driving screw 34. Interlaced with the driving screw 34 is a toothed frame 32, wherein the toothed frame is further linked to the toothed end shaft 30 so that the rotation of the The transmission moves the mount 32 along its axis in the first or second direction depending on the direction of rotation of the motor 8. The linear movement of the mount is translated to the rotational movement of the axis 30 by the intertwined relationship between the mount 32 and the shaft 30. The shaft 30 is attached or integrated with the gear 14 wherein the shaft 30 and the gear 14 are rotatably kept free in the housing through at least one bearing 28 and 16.

The gear 14 in this case (but without limitation) is arranged to interlock with the gear 32. The gear 22 is integrated with or attached to the shaft 18 and maintaining a fixed position in the housing but is free to rotate by means of bearings 20 and 24. As the motor 8 rotates and the toothed mount 32 moves linearly as described above, the consequent rotation of the shaft 30 rotates the gear 14 and through its interlocked relationship with the gear 22 also rotates to the gear 22 which at its the output shaft 18 rotates.

The output shaft 18 is capable of being an extension to the toothed shaft 30. In such an embodiment (not illustrated) the rotary actuator would operate as described above, it would even represent two output shafts; the rotation of the actuator 8 through a drive screw and the shaft. toothed and / or a gear would rotate the output shaft .18 as well as the output shaft extension to the shaft 30. It will be appreciated that the axes 30 and 18 would rotate in opposite directions but this is able to be addressed with the inclusion of an additional gear in an interlaced arrangement with and between gears 14 and 22. In this case, both axes 30, 18 would be self-locking.

In an alternative embodiment, the rotary actuator 8 in Figure 2 may have an individual output shaft, the individual output shaft is the extension to the axis 30. In such an arrangement it will be appreciated that the gears 22 and 14 as well as the shaft and the bearings 20, 24 and 18 would not be required.

At least one output shaft 18 of the rotary actuator 6 has two connecting elements, a first connecting element 124 and a second connecting element 122 (as can be seen in Figure 5). The arrangement of the first and second elements 124, 122 elaborates the backrest and / or the seat with the ability to be joined to the output shaft 18 with its own rotating actuators 6 and as such achieve rotational movement independent against a, or congruent with, the rotation of the shaft 18 and at least one element 124, 122.

The output shaft 18 is capable of rotating through a transmission path which in this case comprises (but is not limited to). A transmission screw and at least one gear or gear shaft. The use of a drive screw allows the rotary actuator 6 to be self-locking in that it maintains a position without the requirement of continuous power. As detailed above, the housing 38 and / or the gear (s), the axes (s), or the mount (s) 32 may be arranged to incorporate and / or interact with a stored energy system which, for example, substantially comprises springs.

Figure 3 illustrates a second embodiment of the rotary actuator. In this embodiment, the rotary actuator 40 operates very similar to the first embodiment and all the functions and / or features (optional or otherwise) described in relation to that embodiment could equally apply to it. The rotary actuator 40, however, has been adapted for linear movement as will now be described.

The rotary actuator 40 has a housing 34 that allows the retention of components there and the operation of one or more gears, toothed shafts and / or drive screws as previously described for the first embodiment. The actuator 40 is typically driven by a motor 64, for example the electric motor, but alternatively it can be a manual system. The actuator 64 incorporates a gearbox 68 which is attached (fixedly or detachably) to the motor 64. The gearbox 68 has an output shaft which engages a gear 70.

The gear 70 engages with the gear 72 and rotation of the motor 64 results in rotation of the gearbox 68 and rotation of the gears 70 and 72. The gear 72 engages with the drive screw 62 where the screw transmission 62 can be maintained within the housing through a bearing or bearings 60. The drive screw is intertwined with the toothed frame 66 which engages with the straight mount gear 58. The rotation of the motor 68 rotates the drive screw 62 through its relation to the gear 72 causing the mount 66 and the straight gear 58 to move linearly along the length of the drive screw 62.

Straight gear 58 is intertwined with the gear 56 which engages the shaft 76 located on a bearing or bearings 74. The gear 56 is intertwined with the gear 50 which engages the shaft 78 located on a bearing or bearings 52. All the bearings are held by or within the housing 54. The housing 54 has a space 48 between the gears 50 and 44, the space is used to place a rotatably mounted toothed rack such as 170, 154, 136 or 182 through which it intertwines with the gears 50 and 44 An example of at least one toothed rack 154 can be seen in Figure 6.

The toothed rack can be configured to include double-sided gear teeth that are interlocked with the gears 50 and 44. The gear 44 engages the shaft 42 which is located on a bearing or bearings 46. Therefore, as the motor 64 rotates and moves the frame 66 and the straight gear 58 linearly along the axis of the drive screw 62, the frame 66 through its interlocked relationship with the gear 56 rotates the gear 56 which in turn rotates the gear 50. As the gear 50 rotates it and the housing 54 will move linearly along the axis of the rack 154. The gear 44 through its interlocked relationship with the toothed rack 154 will rotate as the housing 54 moves linearly along the axis of the toothed rack 1154 and through the relationship between the housing and the gears 50 and 44 the intertwined relationship with the toothed rack 154 is maintained.

Figure 4 shows a linear actuator 80. The shape of the linear actuator is not important but a configuration having useful application in this invention is the linear actuator itself as described in the pending international patent application number PCT / GB2010 / 000261. The linear actuator 80 may incorporate its own box or may be incorporated within a support structure such as a vehicle, structure or assembly, the support structure serves as the housing. In the embodiment shown, the actuator 80 has its own housing.

The housing can be coupled with at least one output shaft of the rotary actuator 6 and furthermore can be adapted to join fixed, removably and / or movably at least one of the connecting elements 122 and 124 (seen in Figure 5) of an axis of the output of the rotary actuator 6.

The linear actuator 80 has a piston rod 106 that can be attached to the integrated seat, optionally by one or both of the seat or back portion. The piston rod 106 is entangled with a drive screw 82 which is attached or integrated to the drive column 90. The piston has at least one protuberance 88 which in this arrangement engages the groove 86 located in an inner driving column 82. The driving column 92 is located on the bearing 84. The linear actuator 80 has an electric motor 102 although a manual actuator could also be used. The motor 102 is attached to a gear 104 so that when the actuator 102 rotates, the gear 104 rotates. The gear 104 is interlocked with a corresponding gear on the driving column 92 and as such the driving column 92 will rotate as a result of the motor 102 rotating.

The rotation of the driving column 92 in turn turns the drive screw 82 and through its interlocked relationship with the piston 106, the piston 106 extends with the protrusion 88 keeping the piston rod 106 in the correct orientation.

The union of the linear actuator can be conveniently achieved with a multi-axis joint such as a bar end.

Figure 5 illustrates the support structure 120 which in the example shown is represented as an assembly. The rotary actuator 6 is coupled with the assembly 126 to form the support structure 120. As shown, the assembly 126 is provided with a plurality of small openings around its perimeter allowing it to be mounted at a suitable location. In one option, the assembly may incorporate at least one linear actuator 80. As mentioned, the assembly may be incorporated within a support structure such as a vehicle body, seat structure or other surrounding structure.

The assembly 126 allows the output shafts (18, 30) to exit in different locations. In a manner as already described above with respect to other axes, the output shafts 18, 30 have connecting elements 124 and 122. In a preferred arrangement, the element 124 is larger than the element 122. Any connecting element is capable of to define a perforation. The linear actuator 80 is capable of being attached to the shaft 18 and an element 124. It is shown that the shaft 18 has two signaling actuators 80 and these are capable of being connected to the integrated seat or the seat or the backrest as the actuator 80 shown for the second one. axis 30.

The linear actuators allow the integrated seat or backrest to move linearly while the rotary actuator allows the linear actuators to rotate and thus the integrated seat or seat or backrest is able to move relative to the inlet rotary and linear input of the respective components.

Figure 6 illustrates the first embodiment of the backrest 2, Figures 7, 8A-8B and 9A-9B illustrate an additional embodiment. It should be appreciated that all embodiments comprise an assembly of modular components, modular components are interchangeable between embodiments that provide a significant number of additional design variations as alternative embodiments without departing from the scope of the invention as claimed herein.

Figure 6 illustrates the backing in a front view and without any fabric such as covers or padding or other detail related to comfort as this will be described later.

The backrest has a pair of actuators 6.

Typically these are rotary actuators and are arranged in coaxial alignment with each other. An actuator includes an output shaft that allows the rotary actuator to be connected to a seat portion or directly to a support structure such as a vehicle body, structure or assembly.

The rotation of one or both actuators 6 rotates the backrest around the shaft of the associated output shaft, in the case shown, this is the shared axis of the actuators coaxially aligned. As illustrated, the actuators 6 are integrated with a structure 188, 132 of the backrest as described below. As illustrated, the backing may have at least one structure per section and at least one section. In a convenient embodiment as shown, the backrest 2 has two structures per section with structures 132 and 188 in the lower section, and 150 and 166 in the upper section.

The operation of the rotary actuators 6 rotates at least one section (and desirably all sections) of the backrest 2 around the shaft of the output shaft (s). The rotary actuators 6 as illustrated are capable of being connected together in a fixed, integrated, separable and / or movable relationship to form a first rotary unit 130. The first rotary unit 130 is connected in a fixed, integrated, separable relationship and / or movable with one or both structures 132 and 188. The rotating unit 130 may be configured to incorporate any or all of the functions and features and configurations as already described for the rotary actuator 6. For example, the unit 130 may include multiple axes of output connected to or integrated with a support structure such as; a seat, vehicle body, structure and / or assembly.

The structures 132 and 188 each are in an operable communication plate 134 consisting of at least one material and incorporating a flexing capacity and / or reaction capacity. Multiple materials may be used each in various regions of the plate and individually providing different bending capabilities and / or reactions in those regions. Desirably two plates 134 are incorporated in the section. The preferred plate configurations 134 are described in more detail below.

A plate 134 incorporates slots 138 and 184 as shown, although the number of slots is not essential. The plate 136 further incorporates a low cover 186. Desirably the cover has a low friction surface. Optionally, the cover has a sheet or other highly polished surface.

Under the cover is a cross member connected in a fixed, integrated, separable and / or movable relationship with one or more of the rotary actuator 40. As previously described, the rotary actuators 40 are capable of linearly moving along serrated racks. 136 and 182 respectively. Since the rotary actuators move linearly in the first and second direction so that the cross member to which they are attached moves in the first and second directions.

The connection between the cross member and the rotary actuator 40 is preferably a fixed column which is located through the slots 136 and 184 respectively. The cross member is desirably configured to be either by construction or choice of material or a combination of both. Most desirably, the cross member is elastically flexible, ie it has a neutral shape to which it is capable of returning when it is not under load.

In the integrated seat, each structure and / or section incorporates one or more toothed zips.

Very conveniently but without limitation, the zipper (s) are rotatably mounted to a structure and allow to rotate about its axis. In an illustrative modeAt least one bearing is located at each end of the toothed rack to allow low friction rotation. A damping element is desirably associated with the rotary assembly and is capable of resisting or assisting the rotation of the toothed rack about its axis. For example, the damping element could be a mechanical spring (of which many suitable alternatives are known in the prior art and could be selected by those skilled in the art).

In a suitable arrangement, one end of the spring is captured in the structure and the other end is joined to the toothed rack. Therefore if the toothed rack rotates from its central position where no rotation load is exerted on the spring then, if the toothed rack moves to the first or second direction then the spring resists rotation. However, if the toothed rack moves in the first or second direction and begins to reposition itself to its neutral, centered position, the spring assists in the return rotation of the toothed rack.

Typically, at least one plate 134 is capable of flexing and as will be referenced above, detail will be given below. However, to maintain the manner in which the cross member and toothed rack operate, some plate operation will be described. Typically, but not limited to, the at least one cross member 176 (generally toward the bottom of the backrest) serves as a lumbar support. This lumbar support will typically receive the primary portion of the load exerted by a seat occupant in which the backrest is incorporated.

In use, as a load is applied the cross member will receive the load and begin to flex in a first direction, sharing and transmitting the load with at least one plate and at least one cushion element through the at least one column flexible as described, and consequently the rotary actuator 40.

As a load is applied and generally increases, at least one plate as part of the assembly including at least one cross member, at least one flexible column joining it to the at least one rotary actuator and the at least one rack toothed and at least one damping element thereof described above, is flexed in the first direction.

The flexion of the plate allows the cross member to flex in the first direction. The flexure of the cross member places a load through the flexible columns that will also flex in the first direction and into at least one rotary actuator 40. The rotary actuator 40 receives a letter through the plate that transmits a load to the actuator housings. The load placed on the rotary actuator moves the actuator in the first direction by applying a rotational force to the toothed racks 136 and / or 182. This rotational force will cause the toothed rack (s) to move in the first direction, this movement will resists by at least one damping element.

The combination of components is repeated through the backrest in the multiple sections providing a fully cushioned backrest system. This provides a backup that can react to changes in the load applied to the backup. In addition, where the load is not evenly distributed, the backrest sections respond to local load instead of an average load on the backrest.

The backrest is conveniently (but not essentially) configured so that an applied load results in movement of the assembled backrest generally in a first direction thereby absorbing the load, and a sensible load provided by the absorber system incorporated within the backrest movement in a Second direction is configured to counteract the load with an equal or amplified force that is transmitted back to the second direction. Desirably, the backup cushion system is configured to act (i.e., flex more quickly) in the first direction and more (i.e., return to a neutral position) in the second direction. There are several ways to do this and these will be discussed in more detail below in the discussion below.

It will be appreciated that the actuator 40 acts both to assist in the cushioning nature of the seat and to have to act by facilitating relative rotational movement between the components. The actuator 40 is attached to the flexible column which is located through a channel 138. Therefore as the plate moves, the relative position of the rotary actuator and thus the flexible column changes in relation to the plate and the channel. Therefore, in order that the operation of the rotary actuator 40 results in linear movement of the cross member, the rotary actuator 40 must be allowed to move relative to at least one plate. As described, this is facilitated by the. incorporation of the toothed rack that has rotational capacity and is damped and serves both to assist in the flexing of the plate and to assist in the provision of a reactive load by means of the backup cushion system.

Figure 6 further shows that each structure 132 and 188 is capable of serving as a structure for a support structure 120 and as described in Figure 5 incorporate at least one linear actuator and one rotary actuator. The support structures 120 are attached to at least one upper structure and at least one lower one. In this case the supporting structures are encapsulated with the upper structures 150 and 166 and the lower structures 132 and 188 respectively of the illustrated backing.

The two support structures 120 are located coaxially. Conveniently, the linear actuators in this case are attached to the rotary actuator of the support structure 120 through a rotating attachment member 144. The rotation member 144 allows the rotary actuator to rotate about its axis. This is clear from the illustration that the rotary actuator 40 uses a different orientation for the motor of the linear actuator. In this configuration the engine is in line and not at 90 degrees as illustrated in Figure 5. Those skilled in the art will appreciate that the engine can be placed in any of a number of suitable alternative orientations.

The rotation element 144 allows the support structure 120 placed on it to rotate relative to the structure. In this case, the structure is represented in a higher section. The upper section in this case consists of two structure sections 150 and 166. Therefore, the ability of the rotary actuator 40 to rotate about the axis of the rotation joint member 144 means that the structure section 150 and 166 are capable of to rotate on the axis of element 144.

The ability of the support structure and the structure to rotate relative to each other as described above allows the structure section such as 150, 166 as well as 132 and 188 to flex. This flexibility operates in parallel with the shock absorbers already described for the backup section. The degree of bending of the structure section can be designed by suitable choice of materials, shapes, etc. For a car seat, it is appropriate to select materials and design to configure the structure section to flex only in high load situations such as those that may be encountered in a speed crash. It is within the capabilities of the person skilled in the art to select appropriate materials and adjust design parameters of the inventive concept to adapt the seat for use in a desired load situation.

The at least one member 120 is partially capable of rotating on the at least one element 144 and as such the linear actuator of the member 120 will remain stationary, i.e., free of rotation. It is also relevant that the at least one element 144 is capable of presenting a damping element that is capable of presenting all the same functions and characteristics as the damping element attached to the at least one toothed rack and thus these functions and characteristics do not they will repeat. Typically, the cushioning element and the flexure of the backrest as well as the cushioning components of the backrest combine to provide both comfort and shock protection to the occupant.

In this case and as illustrated the upper backrest section is indicated by the two support structures 120 and the structure sections 166 and 150. When the members rotationally operate the associated upper backrest section rotates about the axis of the support structures 120 in a first and second direction. When the linear actuators operate the. sections capable of moving away or approaching the associated lower backrest section represented by the structure sections 132 and 188. Therefore, the operation of a linear actuator of the support structure 120 is capable of moving the upper section in the first and second sections. respective linear direction.

The upper backrest section is capable of presenting all the same functions and features as the lower backrest section described. Therefore, all of the back-up cushion components such as plate 156 (134), channels 160 (138) and 164 (184) and cross member 162 (176) as well as toothed rack 154 (136) and 170 (182) ) and the rotary actuators 40 and cover 148 (186) all operate in the same manner as the same components as described with respect to the lower backrest portion. (To avoid doubt in at least one identifier of the lower backup buffer components has been provided in backups in the previous text and are of the same name).

Figure 7 illustrates a further embodiment of the backrest and as previously described, all functions and features of either of Figure 6 or Figure 7 are capable of being used in the at least one backrest 2 as required. The backing in Figure 7 is shown without any cover and / or padding. These upholstery features are described later in the patent.

In this case, the backrest has two sections of structure 132 and 188 and has only one backrest section whereby the structures are continuous. The backing in this case has two plates 134 and 156. The panels have all the same functions and characteristics as previously highlighted for the other backrest section. Figure 7 illustrates the additional features of an opening 198 on a plate 134, 156. In addition, the backrest has a manifold 212 and duct 210. The backrest further has a supply duct 200 and an additional supply duct 204. It will be appreciated that the backup may comprise multiple module modules and multiple components described. Inside each duct there is at least one fan, in the case of duct 200, a fan 192 is located inside the duct and in the case of ducts 204 a fan 194 is located.

Conveniently (but without limitation), the duct can be provided in a branched arrangement, each supply duct has at least one supply rating, as shown, duct 2 has a schedule 202 and duct 204 has a branch 196.

The duct 210 may be connected to an air conditioning system, for example, the air conditioning system of a motorized vehicle in which the seat is placed. The duct allows the air conditioning (heated or cooled and / or filtered) to enter the collector. The collector in this mode consists of an electric motor attached to a cylinder with at least one hole. The electric motor rotates the cylinder so that it is aligned with a hole with at least one of the ducts 204, 200.

The duct 210 is capable of being a multi-channel duct and is thus capable of supplying different types of air. conditioned to the collector such as hot air and cold air. The cylinder receives the supplied air of multiple channels and through rotation and alignment of the orifices with the channels and ducts, supplies air to the ducts 200, 204, for example warm air to a duct 200 and high cold air to the other duct 204.

By taking the duct 200, the air once supplied is driven and / or circulated by the fan 192. The fan will assist in the bag that is pulled up the duct and then be distributed through the branch duct (s) 202 where it will come through the openings. Once the air leaves the holes, it will enter the cushion materials and be deactivated so that the occupant warms up or cools at least in one region. In this case, the at least one region is the top plate 156, however each plate is capable of presenting multiple regions and typically each plate will have at least two regions. Each region through the manifold and channel duct such as 200 and 204 is capable of receiving air conditioning differently (eg, warm or cold, flavored, unified, filtered). For example, the air in one region can be heated and flavored, the air in another is used with removed particles such as pollen.

The same is true of the second pipeline 204. The air once supplied will be driven and / or circulated by the fan 194. The fan will help the air to be pulled up the pipe and then distributed through the branch pipe 196 in where it will come through the openings. Once the air exits the holes, it will enter the cushion materials and be deactivated so that the occupant will warm up or cool down in at least one region. In this case the region is the lower plate 134.

The duct 200 and 204 as well as the branch 196 and 202 desirably comprise a flexible material, for example a rubber variant. The duct and the branch are attached to a plate, for example through a binder such as an adhesive. The backing may include a heating element 208 and this is capable of being attached to the plate or integrated with the fabric covers of the backrest and / or within the cushioning materials. It is further evident that the fans 192 and 196 are capable of operating without the inflow of air or air conditioning through the manifold 212. In this case the duct 204 is capable of being left open and not closed by the manifold 212 and the duct 210 and therefore when the fans operate, they will circulate air around the duct 200 and 204 extracted at room temperature or vehicle air temperature. In the case of a vehicle, an air duct from the vehicle is capable of being positioned near the opening to the duct 200 and 204 so that the operation of the fan extracts air circulating in the vehicle.

Figure 8A shows a flat view of the backrest, Figure 8B contains an expanded view of the backrest structure so that the detail is able to be seen and indicated effectively. In this view at least one plate 156 is shown, however, this figure and the functions and features described herein can be applied to any plate incorporated in the modular seating arrangement of the invention.

The flat view shows the plate with a buffer section. The plate shown has four buffer sections 220A, 220B, 222A and 222B. These buffer sections are typically formed sections and typically but not limited to will be of a type B shape, but any suitable form will be acceptable.

The view also shows the rotary actuators 40 previously described. A first connection has already been described in relation to the rotary actuator. In addition, a second connection can be used, the second connection connected (again the connection mode is not limited). In this embodiment, the second connection 224 is attached to both rotary actuators 40 and a shock absorber connection. The material of the connection can be selected to respond (ie, flex) only to predetermined loading situations.

The connection 224 is connected to the blocks 226A and 226B, whose material is again selected to respond (i.e., flex) only to predetermined loading situations. In this case but without limitation, the blocks will be of a rubber shape. Typically, connection 224 passes through blocks 226A and 226B. The duct 200 as described above is also illustrated with the branch 202.

It will be apparent to one skilled in the art that the connection 224 is capable of crossing the duct without entering the duct and therefore the duct is capable of being in a continuous part with or without a branch such as 202. Desirably, the duct has a shaped section which in this example (but without limitation) is formed similar to an "N" section, this allows the connection 224 to pass through the effective path of the duct without entering the duct.

The backrest is desirably covered in one or more layers of upholstery. The layers may comprise any combination of materials with characteristics selected from; cushioning; absorbency and capacity of energy deformation. A layer of external fabric provides aesthetic appearance and comfort to the touch. In this case, the backrest section has an outer fabric 242 that typically surrounds the entire backing. Under the outer fabric is at least one layer of foam 214 and one layer of confined fluid (eg, gel filled) 216, finally in this embodiment, a layer of high density foam 218 is also provided.Hro In a preferred example, the gel is a sealed unit, the sealed unit comprises at least one section. The sealed unit may contain one or more valves or valve-like elements. The valve-like element of a first section is capable of allowing the gel or other fluid to move within at least one other second section depending on the amount of pressure applied to the first section.

Typically, but not limited to, each section is capable of presenting at least one valve or valve-like element that is capable of opening in a first direction and / or at least one valve or a valve-like element that is capable of to open in a second direction and / or at least one valve or valve-like element that is capable of opening in a second direction.

Typically, but not limited to, the at least one valve or valve element in the at least one section that is capable of having different opening pressure requirement in the first and / or second direction. Typically but not limited to at least a first valve or a valve member is capable of having a different opening pressure requirement in the first and / or second direction than that of at least one second valve or valve element therein at minus one section.

Figure 8B illustrates the at least one plate 156 of the at least one backrest section as described with the at least one damping section 222B. The plate has at least one neck 240 which is capable of joining or integrating permanently or removably and / or movably to the at least one section of structure 132. Between the at least one section of structure and the at least one collar is typically but not limited to a bearing 238. Typically but not limited to the bearing is a nylon or other flat bearing. Typically but not limited to the neck it is movably attached to the structure and the movement is around the axis of the structure and assisted to be low friction tgh the bearing 238.

Around the outside of the plate neck 240 is typically a dust jacket 244, this to allow a low friction surface against the interior of the fabric cover 242 and prevent any lubricant from touching the fabric. At least one section of structure and in this case, but not limited to 132, is capable of presenting several internal components that are capable of assisting at least one section of structure with strength and / or flex design and / or other features and functions such as ventilation and / or electrical wiring and / or other such aspects. This represents internal multiple-use design that allows the structure to be as compact and as efficient of space as possible.

In this case, but not limited to three different internal components that are illustrated, the first is the upper central unit 232. The upper central unit is located at the top and bottom of the internal space and integrates or permanently joins the permanent structure at the kernels 234 and 230 and typically but not limited to two ribs 232 that are used on either side of rib 234. Typically but not limited to core components that are permanently or removably attached and / or integrated with each other. The connection provided by the component 232 allows forces to be effectively transmitted to the at least one rib 234 and 230. The ribs are then capable of adding strength to the structure and / or as mentioned are designed so that the structure is allowed to flex. under certain conditions and / or charges and in certain directions against these charges.

The channels created by the at least one rib of the upper central component 230, 234 and 232 respectively allow compressible or non-compressible fluid, conditioned or otherwise, to be distributed tgh the structure, this can be used for many different applications. Typically air conditioning it is distributed through the structure and leaves the structure through at least one hole. Each channel is capable of supplying air conditioning to at least one region and typically each channel supplies the air to a different region. The at least one channel and at least one hole is capable of connecting to the at least one branch such as 202 sufficient to allow the compressible or non-compressible fluid to flow. It is possible that different types of compressible or non-compressible fluid are in different channels or are in the same channel in different sections, wherein typically each channel is capable of presenting fluid separators that seal at least one section of at least one channel is from at least one other section of the same channel.

Also the fluid 'no. compressible is able to be fireproof or otherwise fireproof, so that in the case of fire in the vehicle or chair or other of those the non-compressible fluid is able to leave the at least one channel and / or at least one section of structure to extinguish or limit fire.

It is also true in terms of compressible fluid terms in that an inert gas is capable of being located in the at least one channel and / or structure and leaving the structure under certain conditions.

In addition, the non-compressible fluid is capable of pressurizing or otherwise adding strength and / or different properties to the at least one structure. Further, the compressible fluid is capable of being oxygen and such oxygen is able to circulate through the at least one channel and exit through at least one orifice or structure and / or through the orifice within the at least one branch. such as 202. This ability to supply oxygen in such a manner is capable of encapsulating the occupant in an oxygen enriched atmosphere which is capable, for example, of increasing the response of the driver or, for example, allowing an elderly person or an occupant of low mobility undergo the wear of an oxygen mask.

Other compressible fluids are capable of being delivered in this way and include those that are capable of serving as a stimulant or a relaxant that affect the occupant. The method is also capable of applying other forms of drug delivery which include the placement of particles in the compressible fluid to be inhaled by the occupant.

With reference to Figures 8A and 8B the at least one plate has been previously indicated in Figure 6 in relation to the capacity of the backrests for flexionarsé and all the functions and characteristics thereof are capable of being additional to all functions and added characteristics with those described here. As previously described, covers such as 214, 216, 242 and 218 are capable of being placed on the at least one plate and as such the cross member as described in Figure 6 would be located under at least one of the covers as would typically be indicated for all covers as indicated.

Therefore, as the occupant puts pressure on the covers, so they place pressure on the at least one plate and the at least one cross member. As previously described, this pressure is capable of causing the cross member and / or the plate to flex in line with the designed and / or material characteristics as well as the relative bending properties and properties of the other shock absorbing components. back. In this case and in addition to the previously described, as the at least one plate begins to flex, the channels formed such as 220A, 220B, 222A and 222B will generally open more or close and thus move in their first respective addresses. Typically, the formed channels 220A and 222A will be closed for channels 222B and 220B will open depending on the overall pressure and its design and when pressure is released they will move in the second direction which means that one of the inner channels is opened and the channels exteriors are closed. Therefore, the rigidity or relative reflection of the at least one channel formed will directly affect the movement of the at least one plate and all of the other backup cushion components.

Upon further examination, as pressure is applied to the covers of the at least two inner channels 22OA and 222A will be closed and this first opens the at least one corresponding outer formed channel 22OB and 222B. However, as the pressure increases and the inner channels close more, the outer channels will begin to open further as the at least one neck 220 will begin to rotate slidably around the at least one structure shaft moving in its first respective direction and when pressure is released the neck will move in the second direction. Thus, the damping action is bent several times, first the interior formed channels, secondly formed outer channels, thirdly the relationship ben the neck and the outer formed channels and finally the relationship ben the neck and the at least one structure. All these are able to be manipulated in terms of their capacities and bending properties depending on the desired output and in relation to the other backup cushion components.

In addition, the connection 224 between the rotary actuators is capable of having properties and bending characteristics such as the blocks 226A and 226B. Therefore, as the inner shaped channels deform, generally closing and the at least one plate begins to flex and form a generally curved shape, so that the axis of the blocks move relative to the plate curvature and properties and flexing characteristics of themselves as well as the interior and exterior channels and the other backup cushion components.

Therefore, as the occupant puts pressure on the covers, pressure is applied to back-up damping components and the previously used components and mainly the inner and outer channels, the blocks and the connecting member 24 will move in their first rows they will move respectively and the cross member and the plate will move slightly but not limited to form a respective curvature to the characteristics and properties of all the components indicated above. As the pressure of the occupant is reduced, the components will move in the second direction with respect to the characteristics and properties of all the components indicated above.

Each component is capable of presenting different properties and / or features not only in the first and second directions but also with respect to limits within each direction with respect to pressure and movement completed. Therefore and purely for example if the general displacement of the combined components was X then to the middle of X the properties and characteristics would change and for example the general bending of all the components is able to be smaller (the response of components becomes rigid) and / or half of X the response may change with respect to the pressure applied in j so that if more pressure is applied regardless of or in combination with the displaced general quantity the response of the components becomes stiffer, but at the same point displaced in the first direction the response for a lower pressure may become less rigid and more flexion can be observed. Typically, but not limited to this is also true for all circumstances in the second direction, however, the second and first address capabilities and properties are capable of being different.

Typically, the various components of the system are capable of varying in terms of stiffness by simple adjustment means. For anyone skilled in the art, the connection 224 may have a threaded screw that is capable of tightening or loosening to alter the tension of connections and thereby alter the response of the general backrest at applied pressure. In other cases, different blocks and / or cross members and / or plates and / or bearings such as 238 can be used. It is also possible to incorporate pneumatic and / or hydraulic adaptability into the backrest shock absorbers and in relation to all other components of the backrest. backup where relevant. The most obvious location would be to replace the connection 224 with a pneumatic or hydraulic cylinder. Typically the cylinder (pneumatic or hydraulic) is capable of adjusting in terms of response.

It is also a consideration that typically the at least one layer of gel fluid 216 has holes through which the non-compressible and / or compressible fluid is able to pass. Typically but not limited to at least one foam layer on and under the at least one layer 216 will typically have corresponding holes for the same purpose. However, and typically but not limited to the at least one foam cap closer to the outer cover 242 will not have any of the holes so that the non-compressible and / or compressible fluid diffuses over a larger area and generally in a substantially uniform across the region of interest.

The ability of the components as indicated to react differently when exposed to different pressures and at different points displaced in the first and second direction allows each of the characteristics and properties to vary so that during a high pressure, the displacement scenario High that is able to occur very quickly (over a short period of time) means that the backrest is capable of presenting designed features and properties whereby in a collision (where the seat and / or backrest to conform to it or in a vehicle) the occupant is able to focus generally and endure optimally regardless of the shock vector (direction) and impact force.

Purely, for example, if the occupant is located on the first side of the seatback and that seatback is fitted inside a vehicle, the result of that vehicle that is involved in a crash then the components on the first side of the seatback would be exposed to a pressure higher than those on the second side of the backrest. If the characteristics and properties of the first and second side allowed for slower travel in the first direction with a higher pressure but faster travel with a lower pressure, over the course of the movement of first directions the occupant would be better supported and moved towards the center and / or sitting regardless of the backup. Also, if at least one component has properties to return faster on the side that absorbed the higher pressure, then the first side would return (move in the second direction) more quickly than the second side and as such the occupant would be more supported and it would move more towards the center and / or it would focus regardless of the backup.

Of course, any person skilled in the art who trusts that much of the appropriate combination and characteristics are capable of being used regardless of each component regardless of how all the components react with each other in relation to the occupant and the desired effect on the occupant, we have not covered all those here, but the example clearly indicates the capacity of this backup system.

Figure 9A is a front view and the second illustration of the at least one seat 3. All functions and features of the at least one backrest are also capable of being presented on a seat. In view of these, details about features and functions will be provided only where necessary. The seat typically but not limited to, has a cover 304 whereby the cover 304 which is capable of consisting of at least one layer of foam, at least one layer of high density foam and at least one layer of a substance similar to the fluid contained within the section.

The cover 304 is also capable of presenting an outer fabric cover such as a material suitable for the use of the seat. Typically, but not limited to this, the fabric material is capable of encircling the seat section and permanently or removably joining or integrating to the structure. The cover 304 is located on at least one plate 306 whereby at least one layer of the cover is capable of permanently or removably joining or integrating at least one plate. The at least one plate 306 is capable of presenting numerous sections with different properties and characteristics and / or multiple plates are capable of being used in the seat.

Under the at least one plate 306 is a spring plate 308 whereby the spring plate is attached and / or removably or permanently integrates to the at least one seat structure or the seat structure section. Under the at least one spring plate 308 is at least one optional transfer table 302. Typically the optional transfer table is only used when certain types of mechanisms are placed within the mechanism space 300. The transfer table allows it to be transfer forces and movement of a mechanism to the seat and / or backrest and / or the integrated seat 1. Typically but not limited to this, the transfer table is used only where cam or cam-based mechanisms are used and the table Transfer (although not shown) is capable of joining or integrating permanently or removably into the at least one seating structure.

The mechanism space 300 is as is typically mentioned, but not limited to a space where the cam-based mechanisms are capable of being located so that they are capable of moving the integrated seat or seat or seat and a backrest . It will be obvious to a person skilled in the art that other types of mechanisms are capable of being located within the space and that way the space is not limited to the use of cam mechanisms, any suitable mechanism is able to be placed in the space.

It will also be appreciated by one skilled in the art that if no mechanism is to be placed in the space then the overall depth of the seat is capable of being reduced since space is no longer required. Typically, but not limited to this, the at least one cover 304, at least one plate 306 and at least one spring plate 308 will be placed more within the overall height of the structure generally towards the front structure bar 312. As it will be appreciated that this will significantly reduce the overall depth of the seat.

The at least one space is capable of also presenting the at least one optional lower transfer table 310. Typically the lower transfer table has all the same characteristics and functions as the upper transfer table and is used for all the same reasons with respect to the cam mechanisms. The cam or any other of these mechanisms is capable of being secured to either the upper or the lower part depending on the lifting requirements and / or whether the integrated seat 1 is raised or only the seat is being raised. In its most basic form, a mechanism is capable of using the at least one lower plate 310 as a base on which it is to be secured or as a transfer table.

In the first case, the lower part is capable of having any permanent or removable lifting mechanism and / or mobile or integrated and typically "but not limited to taking the cam mechanisms as the at least one cam rotates in the first the seat and / or the integrated seat is raised while the cam mechanism remains secured to the bottom plate, however, it is possible that the cam mechanism is permanently or removably and / or movably attached to the integrated ao with at least a top plate 302. In this case as the cam mechanism typically rotates in the second direction, the seat and / or the integrated seat is raised.This allows any of the upper part of the lower plate to be used as a base and / or the transfer table allows the seat to be mobile independently of the backrest or with the backrest depending on whether the seat is uncoupled from or attached to the backrest.

Typically both the at least one upper and lower plate 302 and 310 are capable of presenting at least one profile and / or at least one guide rail which typically, but not limited to, contains an open or closed channel which is capable of profiling if requires Figure 9B illustrates the approach of the seat 3. The at least one structure 322 is shown and as illustrated the structure is capable of being hollow. The structure is capable of presenting double purpose ribs similar to the at least one backrest structure. The at least one rib 330 is capable of joining or integrating permanently or removably to the at least one structure. The at least one rib adds properties and characteristics of strength and bending to the at least one structure. The at least one rib allows the formulation of at least 6.7 a channel, the channels have all the same functions and characteristics as the channels discussed in relation to the backup channels in Figure 8B. Similar to the at least one previously discussed channel, the channels are able to act as ducts and allow the compressible and / or non-compressible fluid to flow through them. Any type of fluid is then able to leave the structure through a hole and by the ventilation system for the seat where air conditioning or non-conditioned air is allowed to be supplied to different regions of the seat or for other purposes such as it is previously described such as allowing oxygen or other gas or particles containing gas to be supplied to the occupant.

The ribs are also capable of being used to house other articles such as the anchor 328. The anchor 328 is permanently or removably attached to or integrated with the at least one structure and / or at least one rib. The anchor is also permanently or movably attached to or integrated in the at least one spring plate 302. Typically this association forms the first suspension system or cushion for the seat. The at least one plate 306 typically, but not limited thereto, forms the second suspension system or cushion of the seat. The plate has a damping section such as an element formed with at least one curve and / or radius and / or at least one leaf-like leaf spring arrangement. This general curve and / or tighter radius and / or barb-like leaf spring is permanently or removably attached or integrated into a neck 326. The neck has all the same functions and. features that the neck 240. The neck is positioned around the at least one 322 structure and is either permanently or removably or movably attached or integrated into the structure. Typically the neck is movably attached to the structure.

Figure 9B also shows the cover section 304 in more detail, the cover 304 contains at least one outer fabric cover 318, the at least one high density foam cover 314 and the at least one section of gel or fluid 316 and the at least one foam layer 320. Any combination of foam, high density foam and / or gel section or fluid is capable of being used and as such is similar to the backing covers.

The at least one plate 306 and the neck 324 as well as the at least one spring plate 302 and anchor 328 are all capable of being made of at least one material and are capable of making a composite of at least two materials. The materials are capable, but are not limited to, having properties and bending capabilities with the properties and general bending capabilities in relation to the materials and / or designed in features and / or the association and interaction relating to the properties and capabilities of respective bending of the at least one other indicated component.

By taking the first and second suspension system forming the seat cushion components, this is able to be displayed as an occupant increases the pressure on the cover 304, the covers will absorb some pressure and then they will pass the pressure to the less a plate 306. As the pressure increases the at least one plate 306 will begin to flex, typically the curved and / or radius or barb section will begin to move in the first direction and will generally increase its curve or curvature. As the pressure increases, the plate 308 will interact heavier with the spring plate 302 and as such the spring plate 302 will move in the first direction and begin to generally form a curve. As the pressure increases further, the relative section of the at least one plate will begin to move further in the first direction and as such the neck will begin to move in the first direction and rotate about the axis of the at least one structure . The at least one plate 302 will also move more in the first direction and as such the relative section will increase in its overall curvature and increase the pressure that the anchor transfers to the at least one structure.

As the pressure is released, the first and second suspension systems forming the general seat cushion system will move in the second direction. The characteristics of the first and second direction are capable of being different not only in relation to each individual component but also in relation to each of the other components. As such, the seat cushion system is capable of being designed so that the system adapts to the desired use and safety.

Before the examples are introduced, Figure 9B also shows an additional component of the seat cushion system to that of the spring connection 326. The material of the spring connection is capable of being, but not limited to, having properties and capabilities of 'flexion with the properties and general bending capacities in relation to the materials and / or the designed characteristics.

The spring connection is capable of either permanently or removably joining or integrating with both the at least one anchor 328 and the at least one plate 302. Therefore, as the spring plate 302 of the plate becomes. moving in the first direction will also make the connection 326 whereby the connection 326 passes the movement to the anchor 328. The capacity and flexural properties of the connection are capable of being such that the connection does not initially transfer movement or force of the plate to at least one anchor. In addition, the at least one plate is capable of being such that it has at least two and typically but not limited to several projections and each projection is capable of connecting itself and / or to a separate individual anchor and itself and / or to a Separate individual connection.

Properties and characteristics of each of the projections and each of the individual anchors and connections are capable of being different for at least one or the same as at least one of the respective projections and / or anchors and / or connections. The connections 326 are part of the second suspension system and as such are part of the general seat cushion components.

Typically the seat cushion components are capable of being arranged so that the properties and characteristics thereof allow the occupant to be supported in an adapted and / or relocated form in the seat. With respect to adaptation, the properties and characteristics are able to be such that, and purely for example, a user of low mobility who tends to be located more towards one side of the seat instead of the other side since it applies more pressure one side of the seat more than the other is capable of having a more central, supportive and / or corrective posture imposed on them by varying at least one of the properties and characteristics of at least one of the seat cushion components. Typically the variation of at least one of the seat cushion components will observe more rigid components on the side to which they are more oriented and less rigid components on the opposite side. Typically the net result is that the occupant will be centered in the seat with uniform pressure distribution of movement and a posture in addition support and / or correct.

In terms of a relocation, this would occur if the seat were to be located in a vehicle and that vehicle was involved in an accident and typically in a crash. Regardless of the impact vector and regardless of where the occupant is located in the seat unless already in the optimum center position, the properties and characteristics of the seat cushion components are capable of being configured to have different indexes of flexion depending on the amount that have been displaced in the first and second direction as well as the amount of pressure as well as the speed at which the increase in pressure occurs.

Therefore and purely for example, if the occupant is more to one side than the other and a collision or impact occurs in the vehicle, then the pressure will increase more in one region of the seat than the other. In this case at least one of the seat cushion components typically on the opposite side to where the most deviant occupant is will flex more rapidly in the first direction and with less pressure than the cushion components typically on the same side to which the seat is diverted. occupier and in this way the occupant will generally relocate to the center of the seat. In the second direction both sides of the damping components are capable of flexing equally as fast as the other and thus keeping the occupant centered in the seat.

Of course these are examples, but one skilled in the art will understand that at least one of the seat cushion components of the flexural properties is capable of being altered to affect the occupant with a view to allow them a more supported and more secure seat.

Other examples are so that towards the front of the seat cushion components are able to have more bending than the rear region and / or any other of the seat that is capable of more or less bending than another region.

In addition, if the neck 324 can move with respect to the structure, then a bearing and / or lubrication is able to be present between the neck and the structure.

Figure 10A illustrates a simple locking mechanism 350. The simple locking mechanism consists of a motor 344 that is suitably attached to a drive screw 340 which in turn is retained in the bearings 332 and 338. The drive screw is interlocked with a motorized rack nut 342 having a locking pin with end section 336. The system is capable of being mounted on a structure through the bearings and the motor. The system works where the motor rotates the drive screw also rotates and through its interlocked arrangement with the motor rack nut, the toothed motor rack nut travels along the axis of the drive screw so the end section 336 advances and typically enters an assembly and / or a component that is required to be retained. Typically, the assembly allows the toothed motor rack nut to remain in the correct position and free of rotation.

Figure 10B illustrates a simple double locking device 360. The simple device has a motor 370 which is suitably connected to the drive screw 372 which retains bearings 372 and 362. The drive screw is interlocked with locking arms 364 which have at least a rear locking means 366. All of these are typically, but not limited to, a mounting to a base 374. As the motor rotates in the first direction the at least one drive screw rotates in the first direction and of that shape through the intertwined relationship so that the arm 364 moves in the first direction and typically advances through a first structure and into a second structure to lock the first structure to the second structure. When the motor moves in the second direction, the arm 364 retracts and typically moves out of the second structure to release the first and second structures even allowing the arm 364 to remain and retain the first structure. In addition at least one rear locking means 366 will engage a component that is permanently or removably attached or typically integrated with a top or bottom transfer table and as such the first structure is secured to the transfer table.

Figure 11 illustrates a plan view of the seat 3.

For clarity, the flat view of the seat has been divided between two figures, this Figure 11 and Figure 12. In this Figure 11, the seat can be seen having at least one structure. Typically the at least one structure has at least one component. In this case, but not limited to the structure, it has four components, the outer side pieces 322 and 380 and the rear and front parts 376 and 312 respectively. The components 380, 376 and 312 are capable of presenting the same ribs as those described in relation to the piece of structure 322 in Figure 9B.

Figure 11 illustrates that at least one plate 306 is attached as previously indicated. Typically, but not limited to this, the plate is capable of being in several individual sections or a main section where each section is capable of presenting different properties and bending characteristics. The at least one plate is shown here cut away so that the aspects under the plate are able to show better.

As illustrated, at least one double locking means 360 is capable of being located within the boundaries of the structure. The double blocking means have been previously described. In this case the double locking means would be coupled with the backrest (not shown) whereby the backrest structure would have extensions that would be coupled with the arm of the double locking means. Therefore as the double locking means advance in the first direction, the locking arms 364 (shown in Figure 10B) would pass through the first structure which in this case would be at least one backrest structure such as 132 and / or 188 (of Figure 6) and within the second structure that in this case it would be the seat structure typically corresponding to 380 and 322 and that way the backrest would be secured to the seat.

As the double locking means retracts in the second direction, the locking arm would be removed from the seat structure but retained in the backrest structure. When the locking arm retracts and the rear locking means 366 (of Figure 10B) engages with at least one suitable component on the lower transfer table 310 and thus the backrest would be retained to the lower transfer table. This means that once the backrest is retained to the transfer table and uncoupled from the seat, the seat is able to move independently of the backrest. Typically the double locking means are located with the seat structure limits as shown and typically these are located on opposite sides of the seat and are generally coaxial.

Typically, the backing structure would pass through the back structure 376 whereby the backrest structure can further be locked in position by the at least one locking unit and typically two locking units. As the backrest engages the seat, the end section of locking units 336 advances and moves within the backrest structure, applying pressure to the backrest structure and locking in position to move with the seat. Typically if the locking means is retracted the end section retracts and unlocks and depressurizes the backrest so that the seat is able to move independently of the backrest.

The seat structure is also capable of presenting at least one supporting structure 120, whereby at least one and typically two are located in the seat structure either on the front and / or on the rear part. The illustration shows two support structures at the rear of the seat structure with the linear actuator sections within the seat 380 and 322 respectively. Typically the at least one support structure is permanently or removably attached and / or integrated within the seat structure. The support structure typically has two sections as described, the linear actuator section and the rotary actuator section. In this case, the rotary actuator sections are coaxially located and are capable of being permanently or removably attached or integrated to a structure or a vehicle or an assembly or other supporting structure located in the structure and / or the vehicle and typically this is achieved through the at least one pivot actuator output shaft of support structure.

The backing as mentioned is able to connect to the seat as described above and the backrest as described also has its own rotating capability. Therefore the seat is capable of being attached to a structure or a vehicle or a mounting or other supporting structure so that the rotation of the at least one pivoting member of the seat (as shown here) results in the backrest and seat that it rotates on the axis of the at least one shaft of the output shaft of the support structure 120. It is also evident that the extension of the linear actuators will move only the seat but also the backrest (if connected to the seat) linearly. The linear and rotary actuators of the at least one support structure .120 are capable of operating simultaneously or independently at the same or different rotation speeds. It is also evident that the seat support structure is capable of moving the seat linearly and rotatably with or without the backrest that is connected to the seat.

The rear part of the structure 376 can have at least one locking device 350. The locking devices are typically encapsulated in the structure. The locking devices are shown so that when the backrest is positioned through the seat structure as described above and is secured within a respective location of the locking members 360 the two locking devices can also operate and as such the blocking means 366 (of Figure 10A) will advance in the first direction and serve to further retain the backup.

Figure 12 illustrates an additional flat view of the seat 3, the flat view showing the at least one plate 310 with many projections on both sides. The illustration shows a manifold 384 and a connection 382 that are the same and have the same functions and characteristics as the manifold 212 and the connection 210 of FIG. 7. The detail of the functions and the characteristics will not be indicated a second time in detail and which has been previously detailed. However, and typically, the manifold is capable of delivering compressed and non-compressible conditioned or nonconditioned fluid within at least one duct and / or region or region subsequent to the at least one seat. Typically the same manifold is capable of being used both for the seat and the backrest and to supply fluid, conditioned or non-conditioned, compressible or non-compressible, different or equal to each or at least one region or duct therein.

In this case, the collector supplies at least one region of the seat. Typically the seat has at least four regions but in this case the seat is shown with two regions. The left region 394 and the right region 396 are capable of receiving the fluid supplied by which and similar to the backup fans 392 and 388 regardless of 388 with respect to each region circulates the fluid around the region. The at least one plate is capable of presenting at least one hole 386 and typically multiple orifices per region. Therefore the fluid is able to exit the holes and cover 304 towards the occupant. Typically, but not limited to the at least one cushion layer immediately below the cover 310 and typically, but not limited to 314 no holes will be present and thereby deactivate the fluid on the region, however the cushion layers under 314 such as 316 and 320 typically, but not limited to, have holes aligned with the holes in the plate to allow the fluid to more easily reach the outer cover 318.

The seat is also capable of presenting at least one of the heating elements 390, the heating element is capable of being retained for the plate 310 or encapsulated in or within the cover caps 304 such as 314, 316 and 320 of Figures 9A and 9B.

Both the seat and the backrest are capable of presenting at least one section of gel or fluid as indicated, in the case of the backing this is 266 and in the 316. Each. one of the gel or fluid sections is capable of presenting at least one section and typically has multiple sections. Each of the at least one section has the ability to present at least one valve or one valve element.

The at least one valve or valve element has the ability to open relative to the pressure of the gel or fluid within this section or at least one adjacent section, in that way, when in gel or fluid in at least one section it reaches a certain pressure the at least one valve or valve element can be opened or remain closed, therefore the fluid or gel can be moved to at least one other section or be retained in at least one section. Further, when a certain pressure has been achieved and in the case of a valve or valve element that opens, then the valve or valve element will close and thereby retain some or none of the gel or fluid. Each of at least one valve or valve element is capable of opening and / or remaining closed with respect to different conditions which may include temperature and pressure as well as which pressure increases or decreases.

Purely, as an example and not limited in any way, many sessions may be present within the at least one section 216 and / or 316. Each section is capable of presenting at least three valves whereby the fluid or the gel is able to enter and exit the section different from other sections. Therefore, if the at least one first section against the side of the seat and / or backrest is taken, then at least one second section surrounding the first is capable of moving fluid or gel within the at least one first section. when the pressure increases on this one.

Typically, this occurs when, for example, a vehicle begins to corner and the pressure of the occupant increases toward the seat and / or backrest side. As the occupant increases the pressure resulting from cornering forces at least one valve of the at least one second section is able to open and transfer gel or fluid into the at least one first section. This increases fluid or gel in the at least one first section and as such increases the support able to be provided by the first section to the occupant on the side of the seat and / or the backrest and in that way is able to help maintain the occupant usually centered on the seat and / or the backrest.

This is true in terms of a shock whereby forces are exerted on the occupant and as such the pressure applied to the at least one. section and typically at least two sections change with respect to the direction of impact and the magnitude of the load. In this case the at least two sections and at least one valve or valve element there are capable of being arranged so that the occupant is supported and able to be generally centered in the at least one seat or backrest.

Typically, but not limited to the at least two sections and at least one valve or valve element there are capable of being arranged so that the occupant's posture is also generally adjusted both to provide optimum support and maximum safety protection.

As a further example, typically but not limited to this, an elderly person or an occupant of reduced mobility is also able to benefit from the use of fluid and / or gel. When using the seat and / or backrest in a conventional domestic type chair, as the occupant increases pressure resulting from the medical condition, the at least a second section and at least one valve is able to open and transfer fluid gel within the at least a first section. This increase in fluid or gel in the at least one first section increases the support able to be provided by the first section to the occupant and thus helps keep them centered on the seat and / or backrest and increase the pressure release where the it requires more.

This is also true in terms of a pressure whereby the pressure exerted by the occupant resulting from how they feel and / or the shape of their body and / or any condition such as reduced mobility is able to be used so that the applied pressure at least one section and typically at least two sections and at least one valve or valve element there are capable of being arranged so that the occupant is supported with a generally better posture and / or generally centered on the at least one seat or backrest . The at least one section and / or at least one valve or valve element there is capable of adapting to any occupant or requirement of use. It is also preferable that the at least one section and / or at least one valve or valve element there be capable of being designed and the possession and / or possessions of the occupant integrated with the cushion components of the seat and / or backrest in whole or in part. part.

In addition, the properties and characteristics of seat cushion and / or backrest components and especially with respect to bending, both as a whole and in part, are capable of being different and / or at least one component there is capable of being different from the other. minus another component there. However, the back cushion components and the seat cushion components as well as the properties and characteristics of at least one section of gel and / or fluid and especially with respect to flexion and / or movement of fluid or gel relative to pressure are able to harmonize. Typically, harmonization is to optimize support for the occupant and increase the security protection offered to them.

Purely for example, typically the seat cushion components and the backrest and / or at least one section of fluid or gel with its at least one valve or valve element are capable of being arranged so that the properties and characteristics thereof allow the The occupant is supported in an adapted and / or relocated form on the seat and / or backrest and therefore the integrated seat.

With respect to adaptation the properties and characteristics are capable of being such that and purely for example, a user of low mobility who tends to be located more towards one side of the seat and / or backrest, applies more pressure to one side of the seat and / or backing the other to be able to move to a more central, corrective support posture imposed on them by varying at least one of the properties and characteristics of at least one of the seat and / or backup cushion components and / or the at least one section of fluid or gel with its at least one valve or valve element.

Typically the variation of at least one of the seat and / or back cushion components and the at least one section of fluid or gel with its at least one valve or valve element will observe more rigid components and / or pressure bearing values higher on the side to which they are more inclined and less rigid components and / or lower pressure support values on the opposite side.

Typically the net result is that the occupant will be centered on the seat and / or backrest with uniform pressure distribution of movement and a more supported and / or corrected posture.

In terms of a relocation, this could happen if the seat and / or backup could be located in a vehicle and that vehicle was involved in an accident and typically a crash. Regardless of the impact vector and magnitude of the crash and regardless of where the occupant is located in the seat and / or backrest, the properties and characteristics of at least one cushion component of seat and / or backrest and / or the less a section of fluid or gel with its at least one value or valve element are able to be configured to have different flexion rates and / or valve opening and / or closing pressures depending on the amount they travel in the first and / or second direction and / or the volume of fluid or gel in them as well as the amount of pressure and / or speed at which the increase in pressure occurs.

Therefore and purely for example, if the occupant is already in the optimum position, it will tend to stay in the optimum position, however, if the occupant is more to one side than the other and a collision or impact occurs in the vehicle, then the pressure will increase more in one region of the seat and / or backrest than in the other.

In this case at least one of the seat and / or backrest cushion components typically on the opposite side to where the occupant is deflected will flex more quickly in the first direction and with less pressure than the cushion components typically on the same side as where the occupant is diverted and / or at least one section of fluid or gel on the opposite side to where the occupant is diverted will not receive any fluid or gel from the at least one other fluid or gel section from the side to which the fluid is diverted. However, the at least one section of fluid or gel on the deviated side can open at least one valve to allow some fluid or gel to move to at least one other fluid or gel section on the same side and to that form the occupant will usually relocate to the center of the seat and / or backrest. In the second direction both sides of the seat cushion and / or backrest components are able to flex equally quickly from each other and / or less a fluid or gel section on both sides can open at least one valve and evenly distribute the fluid and / or gel and in this way keep the occupant centered in the seat.

Of course these are examples, but one skilled in the art will understand that the flexural properties, at least one of the seat cushion and / or backrest components and / or at least one section of fluid or gel will be able to be aware to affect the occupant with a view of allowing them a more supported and safer seat and / or backup. Other examples are such that towards the front of the seat and / or the bottom of the backrest shock absorbers and / or at least one section of fluid or gel with at least one valve and / or valve element are capable of more flexing and / or opening and closing at different pressures that the rear and / or upper section and / or any region of the seat and / or backrest and / or at least one valve of the valve element of the at least one fluid or gel section is capable of move more or less flex and / or open and close at different pressure than another region and / or any other valve and / or valve element in any other fluid or gel section.

It will further be appreciated that the at least one structure of the seat and / or the backrest is capable of having properties and bending characteristics that are capable of being harmonized with the seat and / or backrest cushion components and / or the at least one section. of gel or fluid and the at least one value thereof. This means that the above examples in terms of bending would incorporate the bending provided by the backrest and seat structure with the same results, as those of optimized occupant safety, support and comfort.

The present invention utilizes the prior art of other Corcost patents such as and including the Gearbox patent. It will also be obvious to those skilled in the art that the formation of the seat described herein is not limited only to the automotive sector, it can also be applied in the seat formulation to any seat for any sector such as a medical chair, dental chair, lounge chair or any other suitable chair application.

It is noted that in relation to this date, the best method known by the applicant to carry out the aforementioned invention is the. which is clear from the present description of the invention.
