Abstract
Description
Technical Field
[0001] The present invention relates generally to a vehicle seating assembly and, more particularly, to a vehicle seating assembly having an adjustable component configured to adjust in response to input from a sensor mechanism. Background Art
[0002] Vehicle seat assemblies currently have more adjustment features to provide customized support configurations for individual drivers. Typically, the seat assembly is adjusted using input from the driver to adjust various components to a desired position, where the components remain until adjusted later by the vehicle occupant. During use, and particularly during use of a high-performance vehicle, the vehicle occupant may be subjected to forces that cause a weight perception. These forces may include different types of accelerations, such as G-forces. Particularly during cornering situations, a vehicle occupant may move or tilt in a particular direction due to G-force accelerations. Vehicle occupants vary greatly in various parameters such as size and mass. Therefore, lateral acceleration forces affect different vehicle occupants differently. Therefore, it is desirable to provide a vehicle seat assembly in which the adjustable features are programmed to adjust as needed in a manner that helps the vehicle occupant resist the effects of the lateral acceleration experienced by supporting the vehicle occupant.

[0073] For the purpose of the description herein, the terms "upper", "lower", "right", "left", "rear", "front", "vertical", "horizontal" and their derivatives shall be used in conjunction with Figure 1 The invention is oriented in the following embodiments. However, it should be understood that the invention can take various alternative orientations unless expressly indicated to the contrary. It should also be understood that the specific devices and processes shown in the drawings and described in the following specification are merely exemplary embodiments of the inventive concepts defined in the appended claims. Therefore, unless the claims expressly state otherwise, the specific dimensions and other physical characteristics related to the embodiments disclosed herein should not be considered limiting.
[0074] Reference now Figure 1 , the vehicle seat 10 is shown disposed within an interior 12A of a vehicle 12. Specifically, the vehicle seat 10 is disposed in the vehicle interior 12A adjacent to a dashboard or instrument panel 13. Figure 1In the embodiment of the present invention, the vehicle seat 10 is located in the driver's side seating area. However, it is contemplated that the vehicle seat 10 or its various components and structures may be disposed in other seat assemblies disposed in other areas of the vehicle interior, such as the passenger side seating area, the rear seating area, or the third row seating area. The vehicle seat 10 is supported on a track system 14 disposed on a vehicle floor support surface 15 and generally includes a generally horizontal seat portion 16 and a generally upright seat back 18. A headrest assembly 19 is disposed on an upper portion of the seat back 18. It is contemplated that the seat back 18 is a pivoting element configured to pivot relative to the seat portion 16. The seat portion 16 generally includes a central support portion 16C having protruding tabs or side bolsters 16A, 16B disposed on opposite sides thereof. The side bolsters 16A, 16B are separated or spaced apart from each other by the central support portion 16C and are generally disposed at an inward angle directed toward the central support portion 16C. When the vehicle 12 is in motion, the side bolsters 16A, 16B are configured to provide support to a vehicle occupant seated in the vehicle seat 10. Similarly, the seat back 18 includes the side bolsters 18A, 18B and an upper loop portion 18D. The side bolsters 18A, 18B and the upper loop portion 18D are generally angled toward a central support portion 18C of the seat back 18.
[0075] The various parts of the seat portion 16 and the seat back 18 are Figure 1 1, which is covered with a trim seat cover 20 covering various cushioning materials CM for providing increased cushioning support to a vehicle occupant in both the seat portion 16 and the seat back 18. The seat cover 20 is intended to be composed of a suitable natural or synthetic material, or any combination thereof, that is used to generally cover the cushioning material CM of the vehicle seat 10.
[0076] Reference now Figure 2 , the vehicle seat 10 is shown removed from the vehicle interior 12A ( Figure 1 ).like Figure 2 As shown in dashed lines in FIG. 1 , adjustable components 25, 26 are shown disposed in side bolsters 16A, 16B, respectively, of seat portion 16, and adjustable components 34, 35 are shown disposed in side bolsters 18A, 18B, respectively, of seat back 18. Adjustable components 25, 26, 34, and 35 are configured to be adjusted between extended and retracted positions in response to sensor input, as further described below.
[0077] exist Figure 2 In the vehicle seat 10 of FIG. 1 , the adjustable components 25, 26, 34, and 35 are shown in phantom as being in a retracted or stowed position so that the adjustable components 25, 26, 34, and 35 are as shown in FIG. Figure 2The support of the side bolsters 16A, 16B, 18A, 18B of the seat portion 16 and the seat back 18 is not increased as found in FIG. Figure 2 As further shown in FIG. 1 , sensors 40, 42, 44, and 46 are associated with adjustable components 25, 26, 34, and 35, respectively. It is contemplated that sensors 40, 42, 44, and 46 are pressure sensors, such as piezoresistive sensors, that may be integrated into seat cover 20. Sensors 40, 42, 44, and 46 are capable of identifying the position of a vehicle occupant seated in vehicle seat 10 and measuring the pressure exerted by the vehicle occupant's body on various portions of vehicle seat 10. Figure 2 In the illustrated embodiment, sensors 40, 42, 44, and 46 are shown as being disposed directly on adjustable components 25, 26, 34, and 35, however, it is contemplated that sensors 40, 42, 44, and 46 may be positioned anywhere on the vehicle seat for measuring the position of the vehicle occupant's body. In addition, it is contemplated that more than one sensor may be associated with each adjustable component 25, 26, 34, and 35.
[0078] The sensors 40, 42, 44 and 46 are conceived as thin sensors so that they can be sewn into a thin fabric structure that can be sewn directly to the seat cover 20. In use, the sensors 40, 42, 44 and 46 are interconnected with a controller of a data processing system. The controller, described further below, may include multiple controllers that multiplex the inputs from the sensors 40, 42, 44 and 46 so that the controllers can output to the data processing system. The data from the sensors 40, 42, 44 and 46 are processed by the data processing system according to an algorithm that will detect the movement of the vehicle occupant and the pressure exerted by the body of the vehicle occupant on a specific portion of the vehicle seat 10 based on the changes in the values in the large two-dimensional input array from the sensors 40, 42, 44 and 46. Thus, when the vehicle occupant turns, the pressure generated by their body increases on one side of the vehicle seat 10, and the algorithm can detect this change and send a signal to the seat controller to adjust the adjustable components (such as adjustable components 25, 26, 34, 35) on the pressurized side of the vehicle seat 10 to increase support for the vehicle occupant on the side where the vehicle occupant is leaning. When the turning situation is completed, the sensors 40, 42, 44 and 46 are configured to sense the pressure drop and report this to the controller. The controller then returns the adjustable components to the rest position. In this way, the vehicle seat 10 of the present concept provides real-time or active support adjustment for the vehicle occupant.
[0079] Reference now Figure 3 The seat back 18 includes a front support portion 50, which includes an upper support portion 18E and a lower support portion 18F of the seat back 18 covered by the seat cover 20. The upper support portion 18E and the lower support portion 18F are intended to be formed by, for example, Figure 1 The cushioning material CM shown in FIG. 1 is composed of a cushioning material and is expected to be attached to the support structure 52 using a suspension assembly 54. In the illustrated embodiment, the suspension assembly 54 includes upper and lower portions 56, 58, each of which includes a support wing 60, 62 extending forward and outward. The upper and lower portions 56, 58 of the suspension assembly 54 generally define the structure of the side bolsters 18A, 18B of the seat back 18. The suspension assembly 54 is expected to be a polymer component that generally defines a trim bracket for the seat back 18. The support structure 52 includes a seat back frame 64 having a rear panel 66 connected thereto and a front panel 68 shown as being exploded therefrom. In Figure 3 In the illustrated embodiment, the adjustable components 34, 35 are shown as being associated with the lower support flaps 60, 62 of the front support portion 50. It is contemplated that additional adjustable components may be associated with the upper support flaps 60, 62 of the front support portion 50. Figure 3 In the illustrated embodiment, it is suggested that the adjustable components 34, 35 are supported by the polymer portion of the suspension assembly 54 at its support tabs 60, 62. In this arrangement, the adjustable components 34, 35 will be covered by the cushioning material of the upper and lower support portions 18E, 18F of the seat back 18. It is also contemplated that the adjustable components 34, 35 can be supported on the cushioning material of the upper and lower support portions 18E, 18F and then covered by the seat cover 20. In this way, Figure 3 The arrangement of the adjustable components 34, 35 in is contemplated as one of many different arrangements that will provide active adjustable support for a vehicle occupant to counteract acceleration forces realized upon the vehicle occupant.
[0080] like Figure 3 As further shown, sensors 44 and 46 are shown as being positioned adjacent to adjustable components 34, 35, however, it is contemplated that sensors 44, 46 may be positioned anywhere within seat back 18 to appropriately measure pressure applied by a vehicle occupant to determine the position of the vehicle occupant. In particular, sensors 44, 46 may be sewn to seat cover 20 such that sensors 44, 46 are positioned directly adjacent to a vehicle occupant during use. Seat cover 20 may contemplate including fabric material, leather material, vinyl material, or other decorative material (and combinations thereof) known in the art. Figure 3 As further shown in FIG. 1 , the sensors 44, 46 and the adjustable components 34, 35 are operably connected to the controller 70 via leads. As described above, based on data received from the sensors 44, 46 and described further below, it is contemplated that the controller 70 controls the movement of the adjustable components 34, 35 between the stowed position and the deployed position.
[0081] Reference now Figure 4, a seat portion 16 is shown having a cushioning support material 72, which is expected to be covered by a seat cover 20. The cushioning support material 72 is supported by a seat bracket 74, which is further supported by a frame assembly 76. The frame assembly 76 is expected to include a rigid structure having several support structures composed of metal. The frame assembly 76 is further configured to be slidably connected to the track system 14. The seat bracket 74 can include a polymer structure that is generally configured to support the cushioning support material 72. In Figure 4 In the illustrated embodiment, the adjustable components 25, 26 are shown as being located between the seat bracket 74 and the cushioning support material 72. However, it is contemplated that the adjustable components 25, 26 may be supported on the cushioning support material 72 for adjustment directly beneath the seat cover 20. The sensors 40 and 42 are shown associated with the adjustable components 25, 26 and, as described above, may be sewn directly into the seat cover 20 or any other portion of the seat portion 16 to accurately detect the position of a vehicle occupant seated on the seat portion 16.
[0082] Reference now Figure 5 , the vehicle seat adjustment system 80 is shown in an exploded state. Specifically, the adjustable components 34, 35 of the seat back 18 and the adjustable components 25, 26 of the seat portion 16 of the vehicle seat 10 ( Figure 2 ) is shown in an exploded state. The adjustable components 34, 35 of the seat back 18 each include a base plate 82 and an articulated support plate 84. In assembly, the base plate 82 and the articulated support plate 84 are connected to each other in an articulated manner so that the articulated support plate 84 can be articulated or pivoted relative to the base plate 82 between an extended position and a retracted position. Throughout this disclosure, the position of the articulated support plate 84 may also be referred to as a stowed and deployed position or a stationary and support position. The adjustable components 34, 35 also include an adjustment mechanism 86, which is configured to be disposed between the base plate 82 and the articulated support plate 84 in assembly. The base plate 82 includes a connecting side 82C, while the articulated support plate 84 also includes a connecting side 84C. Similarly, the adjustment mechanism 86 includes a connecting side 86C. In assembly, the base plate 82, the articulated support plate 84 and the adjustment mechanism 86 are connected to each other at their connecting sides 82C, 84C and 86C, respectively, to provide an articulated clamshell structure. The adjustment mechanism 86 is envisioned as an air bag 88 that can be operated between an inflated and deflated state. Other adjustment mechanisms known in the art may also be used to move the hinged support plate 84 between the stowed position and the retracted position. With the adjustment mechanism 86 shown in the form of an air bag 88, supply lines 90, 91 are configured to connect to a pneumatic pump 92 and further connected to the controller 70 to supply air to the air bag 88 and inflate the air bag 88. The pneumatic pump 92 is configured to be connected to the controller 70 so that the controller 70 can control the inflation and deflation of the air bag 88 in response to input data from the sensors 44, 46.
[0083] Further references Figure 5 , the adjustable parts 25, 26 of the seat part 16 ( Figure 2 ) are also shown in an exploded state. The adjustable components 25, 26 of the seat portion 16 each include a base plate 102 and an articulated support plate 104. In assembly, the base plate 102 and the articulated support plate 104 are connected to each other in an articulated manner so that the articulated support plate 104 can be articulated or pivoted in a clamshell manner relative to the base plate 102 between an extended position and a retracted position. Much like the adjustable components 34, 35, the adjustable components 25, 26 of the seat portion 16 also include an adjustment mechanism 106 that is configured to be disposed between the base plate 102 and the articulated support plate 104 in assembly. The base plate 102 includes a connection side 102C, while the articulated support plate 104 also includes a connection side 104C. Similarly, the adjustment mechanism 106 includes a connection side 106C. In assembly, the bottom plate 102, the hinged support plate 104 and the adjustment mechanism 106 are connected to each other at their connection sides 102C, 104C and 106C, respectively. The adjustment mechanism 106 is envisioned as an air bag 108 that can be operated between an inflated and deflated state. The supply line 90 can be connected to the pneumatic pump 92 to inflate the air bag 108 under the control of the controller 70. The adjustable components 25, 26 also include a cloth cover 110, which is applied to the hinged support plate 104 at its upper surface to provide a soft exterior of the adjustable components 25, 26 for contacting the vehicle occupant when the hinged support plate 104 is in the extended position. Similar covers can also be envisioned for use on the adjustable components 34, 36 of the seat back 18.
[0084] Reference now Figure 6 , the vehicle seat adjustment system 80 is shown in an assembled state. Specifically, the adjustable components 34, 35 of the seat back 18 and the adjustable components 25, 26 of the seat portion 16 of the vehicle seat 10 ( Figure 2 ) are shown in an assembled state. The adjustable components 34, 35 (FIG. 2) of the seat back 18 and the adjustable components 25, 26 (FIG. 3) of the seat portion 16 Figure 2 ) are located in the upper position and the lower position, respectively, to illustrate the assumed positions of the adjustable components 25, 26, 34, 35 in the seat portion 16 and the seat back 18, as shown in FIG. Figure 2 As described above, the bottom plates 82 and 102 are hingedly connected to the hinged support plates 84 and 104, respectively, so that the hinged support plates 84, 104 define hinge elements that pivot inwardly (toward the central support portions 16C, 18C, respectively) relative to the bottom plates 82, 102 between the extended position and the retracted position. The hinged or pivoting movement of the hinged support plates 84, 104 is respectively Figure 68 and 105. Thus, when the hinged support panels 84, 104 are moved from the stowed or retracted position to the extended or deployed position, the hinged support panels 84, 104 rotate inwardly toward the vehicle occupant to support and center the vehicle occupant.
[0085] Unlike other active vehicle seat adjustment systems, the vehicle seat adjustment system 80 of the present concept provides for selective and independent adjustment of multiple adjustable components 25, 26, 34, 35 as needed. Based on the pressure detected by the associated sensors 40, 42, 44, 46 of the adjustable components 25, 26, 34, 35, the adjustable components 25, 26, 34, 35 are activated in an independent manner as needed. In this way, the vehicle seat adjustment system 80 of the present concept provides active support (i.e., when the vehicle occupant actually changes position in the vehicle seat 10) Figure 2 ), rather than automatically responding to specific vehicle conditions (i.e., lateral g-forces, acceleration, vehicle speed, steering angle). The above-described vehicle conditions may cause other active vehicle seat adjustment systems to be supported when a vehicle occupant has and actually changes position within the vehicle seat. In the present concept, the adjustable components 25, 26, 34, 35 are moved to the extended or deployed position only when pressure is sensed by the associated sensors 40, 42, 44, 46 due to the pressure sensed by the associated sensors 40, 42, 44, 46 applied by the vehicle occupant actually moving within the vehicle seat 10. The inward rotational movement of the hinged support plates 84, 104 indicated by arrows 85, 105 is a generally opposite movement relative to the direction of the pressure sensed by the sensors 40, 42, 44, 46, as described below with reference to FIG. Fig. 9A and 9B Further described.
[0086] Reference now Fig. 7A , seat part 16( Figure 2 ) is shown in a retracted or stowed position. The adjustable member 25 is operated by adjusting the adjustable member 26 ( Figure 6 ) is mirrored so that the following description of the operation of adjustable component 25 is also the opposite of the operation of adjustable component 26. Fig. 7A As shown, the hinged support plate 104 includes an upper surface 104A and a lower surface 104B. The cloth cover 110 is shown as being disposed on the upper surface 104A of the hinged support plate 104. The bottom plate 102 also includes an upper surface 102A and a lower surface 102B. The airbag 108 is shown in a deflated state and is positioned between the hinged support plate 104 and the bottom plate 102. Therefore, the airbag 108 abuts the upper surface 102A of the bottom plate 102 and further abuts the lower surface 104B of the hinged support plate 104, as it is located therebetween. Fig. 7AAs further shown, the strap 112 is shown connected around the adjustable member 25 so that the strap 112 is wrapped around both the base plate 102 and the hinged support plate 104 with the airbag 108 disposed therebetween. The strap 112 is conceived as a flexible and elastic element that biases the hinged support plate 104 to the desired position. Fig. 7A Therefore, if Fig. 7A As shown, the belt 112 is envisioned to be in a stationary position.
[0087] Reference now Figure 7B , since the airbag 108 is inflated from the deflated state to the inflated state ( Figure 7B ), so the seat portion 16 ( Figure 2 ) is shown in the deployed or extended position. As the airbag 108 inflates and moves in the direction indicated by arrow 114, when the airbag 108 abuts the lower surface 104B of the hinged support plate 104, the airbag 108 moves the hinged support plate 104 in the direction indicated by arrow 105 to the extended or deployed position. Figure 7B As further shown, intake air 116 is supplied via supply line 90 from controller 70 ( Figure 5 and 6 ) controlled pump 92( Figure 5 and 6 ) is supplied to the airbag 108. Therefore, Figure 7B In the example of FIG. 1 , it is contemplated that the controller 70 has detected an input signal from the sensor 40 ( Figure 5 ) to activate the pump 92 to fill the airbag 108 to pivotally move the hinged support plate 104 to the extended position relative to the base plate 102. Figure 7B , the belt 112 is shown in a bent position, rather than Fig. 7A In this manner, when the controller 70 activates a signal to deflate the air bag 108, the belt 112 is loaded and ready to move the hinged support plate 104 toward the stowed position in the direction indicated by arrow 118. It is contemplated that the air bag 108 may be deflated by an electronically controlled valve disposed on the air bag or by the supply line 90.
[0088] Reference now Fig. 8A , seat back 18( Figure 2 ) is shown in a retracted or stowed position. The adjustable member 34 is operated by adjusting the adjustable member 35 ( Figure 6 ) is mirrored so that the following description of the operation of adjustable component 34 is also the opposite of the operation of adjustable component 35. Fig. 8AAs shown, the hinged support plate 84 includes an upper surface 84A and a lower surface 84B. The bottom plate 82 also includes an upper surface 82A and a lower surface 82B. The airbag 88 is shown in a deflated state and is located between the hinged support plate 84 and the bottom plate 82. Therefore, the airbag 88 is adjacent to the upper surface 82A of the bottom plate 82 when located therebetween and further adjacent to the lower surface 84B of the hinged support plate 84. As further shown in Figure 8A, the strap 89 is shown as being connected around the adjustable member 34 so that the strap 89 is wrapped around both the bottom plate 82 and the hinged support plate 84, with the airbag 88 disposed therebetween. The strap 89, which is very similar to the strap 112, is conceived as a flexible and resilient element that biases the hinged support plate 84 to the desired position. Fig. 8A Therefore, if Fig. 8A As shown, the belt 89 is envisioned to be in a rest position.
[0089] Reference now Figure 8B , since the airbag 88 is inflated from the deflated state to the inflated state ( Figure 8B ), so the seat back 18( Figure 2 ) is shown in the deployed or extended position. As the air bag 88 inflates and moves in the direction indicated by arrow 120, when the air bag 88 abuts the lower surface 84B of the hinged support plate 84, the air bag 88 moves the hinged support plate 84 in the direction indicated by arrow 85 to the extended or deployed position. Figure 8B As further shown in FIG. 1 , the intake air 116 is supplied from the controller 70 ( Figure 5 and 6 ) controlled pump 92( Figure 5 and 6 ) is supplied to the airbag 88. Therefore, Figure 8B In the example of FIG. 1 , it is contemplated that the controller 70 has detected an input signal from the sensor 44 ( Figure 5 ) so that the controller 70 has activated the pump 92 to fill the airbag 88 to pivotally move the hinged support plate 84 from the retracted position to the extended position ( FIG. 8A ). Figure 8B In the embodiment, the belt 89 is shown in a bent position, rather than Fig. 8A In this manner, when the controller 70 activates a signal to deflate the air bag 88, the belt 89 is loaded and ready to move or bias the hinged support plate 84 in the direction indicated by arrow 122 toward the stowed position. Thus, the belts 89 and 112 ( Fig. 7A and 7B ) defines a biasing mechanism to bias the hinged support plate 84, 104 toward the retracted or stowed position. It is contemplated that the airbag 88 can be deflated by an electronically controlled valve disposed on the airbag or by the supply line 90.
[0090] Reference now Fig. 9A , showing the vehicle seat 10 with the adjustable components 25 and 34 in an extended or deployed position. Thus, in one possible active adjustment scenario, it can be expected that the vehicle occupant will have moved in the vehicle seat 10 to apply detectable pressure to the pressure sensors 40, 44 associated with the adjustable components 25, 34, respectively. Thus, in this scenario, it can be imagined that the vehicle in which the vehicle seat 10 is located may have made a left turn, such that the lateral acceleration force moves the vehicle occupant to the right side of the vehicle seat 10 to apply pressure to the pressure sensors 40, 44. Specifically, a first pressure value PV1 may have been applied to the pressure sensor 44 in the direction indicated by the arrow PV1. The pressure value PV1 is shown in FIG. 9A to illustrate the lateral movement of the vehicle occupant toward the right within the vehicle seat 10. This pressure value (PV1) may be applied by one side of the torso or back of the vehicle occupant when the vehicle makes a left turn. Fig. 9A 1 and 10. A second pressure value PV2 is shown in the figure to illustrate the lateral movement of the vehicle occupant toward the right within the vehicle seat 10. This pressure value (PV2) may be applied by the thigh or hip area of the vehicle occupant when the vehicle makes a left turn. Thus, as the vehicle occupant moves toward the right within the vehicle seat 10 toward the side bolsters 16A, 18A of the seat portion 16 and the seat back 18, respectively, the pressure values PV1 and PV2 are detected by the sensors 44, 40. When the sensors 44, 40 detect the pressure values PV1, PV2, data from the sensors 44, 40 is sent to the controller 70, which then initiates the inflation sequence of the airbags 108, 88 associated with the adjustable components 25, 34, respectively. As the airbags 108, 88 inflate, the hinged support plates 84, 104 pivot inwardly in the directions indicated by arrows 85 and 105, respectively, which are generally opposite to the directions of the pressure values PV1, PV2, respectively. The opposite direction movement of the articulated support plates 84, 104 relative to the pressure values PV1, PV2 provides active support adjustment for the vehicle occupant to counteract the lateral acceleration forces realized on the vehicle occupant. Fig. 9A Although both are shown in the extended or deployed position, it is contemplated that the adjustable components 25, 34 may function independently or in unison in response to one or more pressure values sensed by the sensors 40, 42, 44, 46. In this manner, one or both of the adjustable components 25, 34 may be activated relative to a particular pressure profile applied by a vehicle occupant and sensed by the associated sensors 40, 44 within the seat portion 16 or seat back 18 of the vehicle seat 10.
[0091] Reference now Fig. 9B, shows the vehicle seat 10 with the adjustable components 26 and 35 in an extended or deployed position. Thus, it is contemplated that a vehicle occupant will have moved in the vehicle seat 10 to apply pressure to the pressure sensors 42, 46 associated with the adjustable components 26, 35, respectively. Thus, it is contemplated that, for example, Figure 1 The vehicle 12 shown in FIG. 1 may have made a right turn such that lateral acceleration forces move the vehicle occupant toward the left side of the vehicle seat 10 to apply pressure to the pressure sensors 42 , 46 . Specifically, the third pressure value PV3 may have been applied to the pressure sensor 46 in the direction indicated by the arrow PV3 . Fig. 9B 1 , to illustrate the lateral movement of the vehicle occupant toward the left within the vehicle seat 10. This pressure value (PV3) may be applied by one side of the torso or back of the vehicle occupant when the vehicle makes a right turn. Fig. 9B A fourth pressure value PV4 is shown in FIG. 1 to illustrate the lateral movement of the vehicle occupant to the left within the vehicle seat 10. This pressure value (PV4) may be applied by the thigh or hip region of the vehicle occupant when the vehicle makes a right turn. Thus, as the vehicle occupant moves toward the left within the vehicle seat 10, toward the side bolsters 16B, 18B of the seat portion 16 and the seat back 18, respectively, the pressure values PV3 and PV4 are detected by the sensors 42, 46. When the pressure values PV3, PV4 are detected by the sensors 42, 46, the data from the sensors 42, 46 are sent to the controller 70, which then initiates the inflation sequence of the airbags 108, 88 associated with the adjustable components 26, 35, respectively. As the airbags 108, 88 inflate, the hinged support plates 84, 104 pivot inwardly in the directions indicated by the arrows 85 and 105, respectively. The pivot directions of the articulated support plates 84, 104, indicated by arrows 85, 105, respectively, are generally opposite to the directions of the pressure values PV3, PV4, respectively, aligned and applied by the vehicle occupant. In this way, the pivot directions of the articulated support plates 84, 104 are used to re-center the vehicle occupant after the vehicle occupant has moved position. Furthermore, this centering action in the present system is limited to areas where only pressure is directly applied by the vehicle occupant and sensed by the sensor. No other vehicle parameters initiate movement of the articulated support plates 84, 104, thereby eliminating unnecessary movement of the articulated support plates when the vehicle occupant is not actually moving in the vehicle seat. The opposite direction movement of the articulated support plates 84, 104 relative to the pressure values PV3, PV4 provides active support adjustment for the vehicle occupant to offset lateral acceleration forces realized on the vehicle occupant. Although the adjustable components 26 and 35 are in Fig. 9B10 is shown in an extended or deployed position, but it is contemplated that the adjustable components 26, 35 can function independently in response to sensed isolated pressure values. In this manner, one or both of the adjustable components 26, 35 can be activated relative to a specific pressure applied by a vehicle occupant and sensed by an associated sensor 42, 46 within the seat portion 16 or seat back 18 of the vehicle seat 10.
[0092] As mentioned above, and in Figure 5 and 6 As shown in FIG. 1 , the controller 70 is operably connected to the adjustment mechanism 86, 106 or the airbag 88, 108. The sensors 40, 42, 44, 46 are configured to sense the movement of the airbag along a first direction (such as Fig. 9A and 9B The controller 70 may be configured to sense the force or pressure applied by the vehicle occupants (in the direction indicated by arrows PV1 to PV4). When the pressure value sensed by the sensors 40, 42, 44, 46 exceeds a predetermined value, the controller 70 activates the adjustment mechanism 86, 106 or (the airbags 88, 108) to move the hinged support plate 84, 104 toward the extended position. Therefore, the sensors 40, 42, 44, 46 are operably connected to the controller 70 and configured to sense the force or pressure directly applied by the vehicle occupants. The sensors 40, 42, 44, 46 are also configured to generate output signals to the controller 70. The controller 70 may determine whether the force or pressure value sensed by the sensors 40, 42, 44, 46 exceeds a predetermined threshold. If the force or pressure value sensed by the sensors 40, 42, 44, 46 exceeds a predetermined threshold, the controller 70 may activate the pump 92 to move the hinged support plate 84, 104 toward the extended position to support the vehicle occupants. In addition, the controller 70 can determine whether the pressure value sensed by the sensor drops below a threshold or is no longer detected at all. In this case, the controller 70 can activate the associated adjustment mechanism 88, 108 to move the hinged support plate 84, 104 back to the static or stowed / retracted position.
[0093] In addition, it is contemplated that the controller 70 adjusts the hinged support plates 84, 104 to a degree of extension that is calculated based on the pressure values detected by the sensors 40, 42, 44, 46. Thus, the hinged support plates 84, 104 are moved in the same direction as described above with respect to Fig. 9A and 9B The extent of extension of the hinged support plates 84, 104 is directly related to the pressure values sensed by the sensors 40, 42, 44, 46 and sent to the controller 70. Therefore, the relationship between the extent of extension and the pressure values sensed by the sensors 40, 42, 44, 46 can be calculated in such a way that ... and the pressure values sensed by the controller 70 can be calculated in such a way that the relationship between the extent of extension and the pressure values sensed by the sensors 40, 42, 44, 46 Fig.10, where A = the pressure value applied by the vehicle occupant and sensed by the sensors 40, 42, 44, 46, and B = the extension of the hinged support plate 84, 104. In addition, B may also represent the inflation degree of the airbag 88, 108.
[0094] like Fig.10 As further shown, the pressure values PV1 and PV2 are plotted on Fig.10 , where pressure value PV1 has a value of 5 compared to a value of 2 associated with pressure value PV2. It is contemplated that the pressure values sensed by sensors 40, 42, 44, 46 may be expressed in Pascals (N / m 2 ) or pounds per square inch (psi), but other common pressure units (such as atmospheric pressure (atm), industrial atmosphere (at), bar, inches of mercury (in.Hg), millimeters of mercury (mm Hg) and torr) may also be used. As described above, the present concept is configured to provide movement of the support plate of the adjustable component to an extent commensurate with the pressure value detected by the associated sensor. Therefore, the pressure values PV1 and PV2 are plotted on Fig.10 , and the associated support plate of the adjustable component is configured to move to 5 degrees in response to the pressure value PV1 and to move to 2 degrees in response to the pressure value PV2. Thus, the degree of movement or rotation of the support plate is calculated based on the pressure value detected by the sensor. The degree of movement of the support plate of the adjustable component can be calculated by length (such as the amount (degrees of rotation) that the support plate pivots along the path shown by arrows 85 and 105), by inflation level (such as the degree to which airbags 88, 108 are inflated), or by the degree of inward extension from the resting position of the support plate. As described above, the movement of the support plate of the adjustable component is generally opposite to the direction of the applied pressure value.
[0095] like Fig. 9A and 9B As further shown in FIG. 1 , sensors 40, 42, 44, 46 are located proximate to the adjustable components 25, 26, 34, 35 such that movement of the adjustable components 25, 26, 34, 35 is actively managed in response to local pressure values achieved on or proximate to the adjustable components 25, 26, 34, 35. In this manner, the present concept provides direct support to the vehicle occupant precisely where support is needed.
[0096] While the active support system has been described as providing for movement of the adjustable components 25, 26, 34, 35 in response to local pressure values detected by the associated sensors 40, 42, 44, 46, it is also contemplated that the same support system may adjust the adjustable components 25, 26, 34, 35 when no pressure is detected by the sensors 40, 42, 44, 46. In this manner, when the vehicle occupant initially sits in the vehicle seat 10 ( Figure 1), the system may provide a support effect when the vehicle occupant is seated in the vehicle seat 10. For example, when the vehicle occupant is seated in the vehicle seat 10, one or more of the sensors 40, 42, 44, 46 may not record a pressure reading. Thus, the controller 70 may be programmed to adjust the position of the adjustable components 25, 26, 34, 35 until the associated sensors 40, 42, 44, 46 detect a pressure reading. Thus, the adjustable components 25, 26, 34, 35 may be rotated inwardly to contact the vehicle occupant when seated in the vehicle seat 10 to provide a support feature from the vehicle seat 10 to the vehicle occupant. In this way, the support system may provide a customized configuration for a specific vehicle occupant. When a pressure value (greater than 0) is sensed, or when a threshold pressure value is detected, the inward adjustment of the adjustable components 25, 26, 34, 35 may be terminated. This support feature may be suitable for high-performance vehicles, in which support and customized supports are required to properly position the vehicle occupant in a vehicle with enhanced performance processing.
[0097] The present concept further includes a method of using the components described herein to actively adjust an adjustable component in a vehicle seat. In one embodiment, the method includes providing a seat assembly 10 ( Figure 1 ), the seat portion 16 has first and second side bolsters 16A, 16B disposed on opposite sides of the seat portion 16. The seat assembly 10 also includes first and second adjustable components 25, 26 ( Figure 2 ) and first and second sensors 40, 42 disposed in the first and second side pads 16A, 16B and a controller 70 (operably connected to both the first and second adjustable components 25, 26 and the first and second sensors 40, 42) Figure 3 ). The method also includes the step of detecting a pressure value using one of the first and second sensors 40, 42 and determining whether the pressure value exceeds a predetermined threshold. The predetermined pressure value may be preset by the manufacturer or may be a programmable feature of the controller 70. The method also includes the step of moving the hinged support plate 110 ( 110 ) of the adjustable component ( 25 or 26 ) associated with the sensor ( 40 or 42 ) that detects the pressure value. Fig. 7A ) from the retracted position ( Fig. 7A and 7B) the step of moving the hinged support plate 110 toward the extended position to an extent corresponding to the detected pressure value. The method also includes the step of determining whether the pressure value is below a threshold value. If so, the method also includes the step of moving the hinged support plate 110 toward the retracted position when the pressure value is below the threshold value.
[0098] The method also includes supplying air to the airbag 108 ( Figure 5 ) is inflated, wherein the airbag 108 is positioned adjacent to the lower surface 104B of the hinged support plate 110 when the airbag 108 is in the inflated state. Fig. 7A ) to move the hinged support plate 110 toward the extended position ( Figure 7B The airbag 108 is deflated to move the support plate 110 from the extended position toward the retracted position.
[0099] In another embodiment, a method for actively adjusting an adjustable component includes providing a seat assembly 10 having a seat portion 16. Figure 2 ), the seat portion 16 having a side bolster 16A, an adjustable component 25 and an associated sensor 40 disposed in the side bolster 16A, and a controller 70 operably connected to the adjustable component 25 and the sensor 40 ( Figure 3 In this method, the pressure value is detected by the sensor 40, and the support plate 110 of the adjustable component 25 moves from the static position toward the extended position ( Fig. 7A and 7B ). In this embodiment, the pressure value is associated with a pressure aligned in a first direction, and the step of rotating the support plate of the adjustable component from the rest position toward the extended position also includes the step of rotating the support plate 110 of the adjustable component 25 in a second direction substantially opposite to the first direction of the pressure. The method also includes moving the support plate 110 toward the retracted position when the sensor 40 no longer detects the pressure value.
