DETAILED DESCRIPTION
(10)
(11) During a turning operation, the occupant and the kinetic seat assembly receives a force pushing the occupant and the kinetic seat assembly in an opposite direction of the turning operation. However, a secondary seat cushion frame and a secondary seat back frame of the kinetic seat assembly rotate in the direction of the force and in phase with one another relative to a primary seat cushion frame and a primary seat back frame of the kinetic seat assembly. As used herein, the term in phase describes two objects, for example, the secondary seat cushion frame and the secondary seat back frame, moving synchronously with one another in the same direction. As such, the term out of phase as used herein describes two objects, for example, the secondary seat cushion frame and the secondary seat back frame, not moving synchronously and in the same direction with one another. Further, it should be understood that when two objects are moving in phase with one another, the directions in which those object are moving are similarly in phase with one another.
(12) Embodiments described herein are directed to a locator bracket for attaching one or more fluid reservoirs to the kinetic seat assembly. The locator bracket includes a connector member, a first receiving member provided at a first end of the connector bracket, and one or more clip holes formed in the connector bracket. The first receiving member includes a pressure gauge wall defining a pressure gauge receiving cavity, and a shaft wall extending from the pressure gauge wall and defining a shaft receiving indent. A pressure gauge of the one or more fluid reservoirs is received within the pressure gauge wall, and a shaft of the one or more fluid reservoirs is received within the shaft wall. Various embodiments of the locator bracket are described in more detail herein. Whenever possible, the same reference numerals will be used throughout the drawings to refer to the same or like parts.
(13) As used herein, the term vehicle longitudinal direction refers to the forward-rearward direction of the vehicle (i.e., in the +/vehicle X direction depicted in
(14) As used herein, the term kinetic seat vertical direction refers to the same direction as the vehicle vertical direction. In a configuration in which the kinetic seat assembly is a normal, front-facing seat in a vehicle, the term kinetic seat longitudinal direction refers to a direction parallel to the vehicle longitudinal direction. However, it should be appreciated that other configurations are contemplated in which the kinetic seat assembly is oriented in a direction in which the kinetic seat longitudinal direction is perpendicular, i.e., parallel to the vehicle lateral direction, or some other direction therebetween.
(15) Also used herein, it is to be understood that the turning direction means a direction in which the occupant is turning the vehicle. Similarly, counter-turning direction means a direction opposite the turning direction.
(16) Reference will now be made in detail to various embodiments of the kinetic seat assembly described herein, examples of which are illustrated in the accompanying drawings. Whenever possible, the same reference numerals will be used throughout the drawings to refer to the same or like parts.
(17) Referring to
(18) In
(19) In
(20) The vehicle 12 includes a steering wheel 20 located in front of the driver seat 16 in the vehicle longitudinal direction. The vehicle 12 includes a display unit 22 and a user interface 24. In some embodiments, the user interface 24 includes manual buttons or touchscreen controls provided on the display unit 22. It is appreciated, that the vehicle 12 in which the kinetic seat assembly 10 is provided may be an autonomous vehicle in which no steering wheel 20 is provided.
(21) In use, the occupant controls the turning direction of the vehicle 12 by rotating the steering wheel 20. In doing so, the turning direction side shoulder of the occupant moves downward relative to the counter-turning direction side shoulder, and the turning direction side shoulder moves rearward relative to the counter-turning direction side shoulder. At this time, a steering operation can be comfortably performed if the occupant bends the lumbar spine in the turning direction and shortens a distance between the turning direction side pelvis and the shoulder compared to a distance between the counter-turning direction side pelvis and the shoulder, twists the lumbar spine, and pivotally moves the pelvis in the same direction as the turning direction side shoulder.
(22) When the occupant directs the vehicle 12 in a turning direction, a force is applied onto the vehicle 12 and, thus, the occupant in the counter-turning direction. In a standard vehicle seat not equipped with moving to compensate for this force and allow the occupant to adjust a pelvis or torso position, the occupant will exhibit strain on these joints, including the knees, waist, and shoulders. In a seat in which the seat cushion frame and the seat back frame rotate in opposite directions, this strain on the occupant's joints is magnified.
(23) The present disclosure seeks to eliminate these joint stresses by permitting the occupant seated in the kinetic seat assembly 10 to rotate with the force exhibited on the vehicle 12 during a turn. Thus, the present kinetic seat assembly 10 allows the pelvis and the torso of the occupant to rotate in order to maintain a center of gravity within the vehicle 12 in the direction of the turn.
(24) As the occupant turns the vehicle 12 to the right, the occupant lowers the right shoulder and uses the trunk muscle so as to bend the lumbar spine to the right. This causes the occupant to pivotally move the pelvis counterclockwise in the rolling direction and clockwise in the yaw direction. In addition, the occupant pivotally moved the torso counterclockwise in the rolling direction and clockwise in the yaw direction. During a turn to the right, force is applied onto the occupant to the left. This further facilitates rotation of the torso and pelvis of the occupant to the left due to the momentum of the vehicle 12.
(25) An imaginary line L extends from a front pivot point and an upper pivot point of the kinetic seat assembly 10. With respect to an occupant seated in the kinetic seat assembly 10, the line L generally extends through the shoulders of the occupant and the knees of the occupant. Thus, during use of the kinetic seat assembly 10, when undergoing movement during a right turn or a left turn, the kinetic seat assembly 10 ensures that the shoulders of the occupant and the knees of the occupant remain generally aligned with one another while allowing the occupant's waist to move in respective left and right directions in accordance with the above disclosure.

(30) The outer rear cover portion 63 includes a lower cover member 63A, a first side cover member 63B, and a second side cover member 63C. The first side cover member 63B and the second side cover member 63C extend from opposite ends of the lower cover member 63A. In embodiments, the lower cover member 63A includes a pair of lower openings 63D to provide visual inspection to otherwise hidden components, such as the lateral dampers 258, 260 described in more detail herein.
(31) The central rear cover portion 64 is provided between the first side cover member 63B and the second side cover member 63C and extends from an upper end of the primary seat back frame 56 toward the lower cover member 63A. The central rear cover portion 64 includes a body member 65, a first receptacle 66A, and a second receptacle 66B. The first receptacle 66A and the second receptacle 66B are provided on opposite sides of the body member 65 and define respective cavities for receiving a pair of fluid reservoirs 334, 336, as described in more detail herein. A pressure gauge opening 67A, 67B and a pressure valve opening 68A, 68B are formed in each of the first receptacle 66A and the second receptacle 66B. The pressure gauge opening 67A, 67B and the pressure valve opening 68A, 68B are spaced apart from another along a respective one of the first receptacle 66A and the second receptacle 66B.

(35) The vertical damping mechanism 100 includes first and second vertical dampers 144, 146 interconnecting the primary seat cushion frame 52 and the secondary seat cushion frame 54 due to the connection therebetween by the linkage assembly 60. The first and second vertical dampers 144, 146 include a ball joint 145 provided at a first end 147 thereof to rotatably couple the first and second vertical dampers 144, 146 to the linkage assembly 60, and a ball joint 149 at an opposite second end 151 thereof to rotatably couple the first and second vertical dampers 144, 146 to the primary seat cushion frame 52. The first and second vertical dampers 144, 146 each includes a fluid inlet 144A, 146A for receiving a fluid from a fluid supply.
(36) The lateral damping mechanism 102 includes first and second lateral dampers 258, 260 for facilitating movement of the secondary seat back frame 58 relative to the primary seat back frame 56. The first and second lateral dampers 258, 260 includes a ball joint 277 at a first end 265 thereof to rotatably couple the first and second lateral dampers 258, 260 to the primary seat back frame 56, and specifically the lower plate 79. An opposite second end 272 of the first and second lateral dampers 258, 260 is slidably received in a hole 275 formed in a respective flange 273 extending from the rear surface of the secondary seat back frame 58. Accordingly, movement in a vehicle lateral direction allows the first and second lateral dampers 258, 260 to slide through the holes 275 and permit movement of the secondary seat back frame 58 relative to the primary seat back frame 56. The first and second lateral dampers 258, 260 each includes a fluid inlet 258A, 260A for receiving a fluid from a fluid supply.
(37) Referring still to
(38) It should be appreciated that a pressure within the fluid reservoirs 334, 336 directly affects a speed at which the vertical dampers 144, 146 and the lateral dampers 258, 260 return to an uncompressed state from a compressed state. For example, when the pressure within the fluid reservoirs 334, 336 is increased, the speed at which the fluid flows from the fluid reservoirs 334, 336 to the vertical dampers 144, 146 and the lateral dampers 258, 260 increases. Alternatively, when the pressure within the fluid reservoirs 334, 336 is decreased, the speed at which the fluid flows from the fluid reservoirs 334, 336 to the vertical dampers 144, 146 and the lateral dampers 258, 260 decreases. Additionally, it should be appreciated that a pressure within the fluid reservoirs 334, 336 directly affects a speed at which the vertical dampers 144, 146 and the lateral dampers 258, 260 moves from the uncompressed state to the compressed state. For example, when the pressure within the fluid reservoirs 334, 336 is increased, the force required to move the vertical dampers 144, 146 and the lateral dampers 258, 260 from the uncompressed state to the compressed state increases. Alternatively, when the pressure within the fluid reservoirs 334, 336 is decreased, the force required to move the vertical dampers 144, 146 and the lateral dampers 258, 260 from the uncompressed state to the compressed state decreases. The fluid reservoirs 334, 336 may be any suitable device for controlling the amount, as well as rate, of fluid provided to the vertical dampers 144, 146 and the lateral dampers 258, 260. The pressure within the fluid reservoirs 334, 336 may be caused by any compressible fluid such as, for example, air, steam, or gas.
(39) In embodiments, the fluid reservoirs 334, 336 each includes a pressure gauge 340 for displaying or otherwise indicating a pressure within the fluid reservoirs 334, 336. The pressure gauge 340 may be any suitable display such as, for example, an analog gauge, a digital gauge, or the like. As shown, the pressure gauge 340 is mounted to an upper end of the fluid reservoirs 334, 336 opposite the outlets 334A, 336A.
(40) The fluid reservoirs 334, 336 each further include a pressure valve 342. The pressure valve 342 may be any suitable valve for regulating the pressure within the fluid reservoirs 334, 336 such as, for example, a Schrader valve, a Presta valve, a Dunlop valve, and the like. The pressure valve 342 may be operated to set the pressure within a respective one of the fluid reservoirs 334, 336 and/or maintain the pressure within a set threshold. The pressure valve 342 may be controlled either manually or automatically in response to an external control unit transmitting a signal to an actuator communicatively coupled to the pressure valve 342.
(41) As described in more detail herein, it is desirable to ensure that the fluid reservoirs 334, 336 are specifically positioned during installation on the primary seat back frame 56 and maintained in position after the rear cover 62 is installed such that the pressure gauge 340 and the pressure valve 342 of each fluid reservoir 334, 336 is received within or aligned with a respective pressure gauge opening 67A, 67B and a pressure valve opening 68A, 68B formed in the rear cover 62. Accordingly, the pressure gauge 340 and the pressure valve 342 of each fluid reservoir 334, 336 being aligned with a respective pressure gauge opening 67A, 67B and a respective pressure valve opening 68A, 68B permits the pressure gauge 340 and the pressure valve 342 of each fluid reservoir 334, 336 to be visible and/or accessible through the pressure gauge openings 67A, 67B and the pressure valve openings 68A, 68B. As shown in
(42) Referring now to
(43) The first receiving member 402 has a front surface 408A and a rear surface 410A opposite the front surface 408A. The first receiving member 402 also includes a retaining wall 412A extending from the front surface 408A in a direction opposite the rear surface 410A. The retaining wall 412A includes a pressure gauge wall 414A and a shaft wall 416A extending from the pressure gauge wall 414A. In embodiments, the pressure gauge wall 414A has a substantially circular shape and defines a pressure gauge receiving cavity 418A. However, it should be appreciated that the pressure gauge wall 414A may have any suitable shape corresponding a shape of a pressure gauge 340 to be received within the pressure gauge receiving cavity 418A, as shown in
(44) As shown in
(45) Referring still to
(46) The first receiving member 402 and the second receiving member 404 are identical in structure. Accordingly, similar to the first receiving member 402, the second receiving member 404 has a front surface 408B, a rear surface 410B opposite the front surface 408B, and a retaining wall 412B extending from the front surface 408B in a direction opposite the rear surface 410B. The retaining wall 412B includes a pressure gauge wall 414B and a shaft wall 416B extending from the pressure gauge wall 414B. As shown in
(47) A shaft axis A2 extends coaxial to the shaft receiving indent 434B. As described in more detail herein, in embodiments, the shaft axis A2 is oriented at a non-parallel angle relative to the vehicle vertical direction. In other embodiments, the shaft axis A2 is oriented parallel to the vehicle vertical direction. More particularly, as shown in

(52) Once the locator bracket 400 is fixed to the primary seat back frame 56, the fluid reservoirs 334, 336 are positioned relative to the locator bracket 400 and fixed thereto. Specifically, the first fluid reservoir 334 is oriented and positioned such that the pressure gauge 340 of the first fluid reservoir 334 is received within the pressure gauge receiving cavity 418A of the first receiving member 402. With the pressure gauge 340 received within the pressure gauge receiving cavity 418A, the pressure gauge 340 abuts against the ribs 422A. Accordingly, the ribs 422A reduce the amount of movement the pressure gauge 340 is susceptible to while positioned within the pressure gauge receiving cavity 418A.
(53) Additionally, as shown in
(54) Thereafter, with the first fluid reservoir 334 properly positioned relative to the primary seat back frame 56, a fastening ring 450 positioned around the first fluid reservoir 334 may be secured to the upper member 76 of the primary seat back frame 56 via a threaded fastener 452 or the like, which extends through a hole formed in the fastening ring 450 and a respective fastener hole.
(55) It should be appreciated that the second fluid reservoir 336 is secured to the locator bracket 400 and, thus, the primary seat back frame 56 in the same manner as described above with respect to the first fluid reservoir 334. Specifically, the pressure gauge 340 of the second fluid reservoir 336 is received within the pressure gauge receiving cavity 418B of the second receiving member 404, and a shaft 344 of the second fluid reservoir 336 is received within the shaft receiving indent 434B of the second receiving member 404. Thereafter, a fastening ring 454 positioned around the second fluid reservoir 336 is secured to the upper member 76 of the primary seat back frame 56 via a threaded fastener 456 or the like, which extends through a hole formed in the fastening ring 454 and a respective fastener hole.
(56) Referring again to
