Title: Bariatric Bidet Seat System

Description:
BACKGROUND OF THE INVENTION 
     Embodiments of the present invention generally relate to toilet sear apparatus and system can be used to wash and clean a region of a human body. More specifically, aspects of the present invention provide a method and apparatus for delivering and applying water, medication, and/or a cleaning solution to a region of the body (e.g., genital or anal area, intimate parts, perianal region) of a heavy weight user who may have difficulty to access and drying the region. 
     DESCRIPTION OF THE RELATED ART 
     Bidets and other modern toilet seat systems have been used to spray water and clean private parts of a user while using a toilet. The bidet systems are used for washing the genital and anal areas using cleaning water of appropriate temperature sprayed from the center of the bidet system, instead of a toilet paper after relief of stool or urination. Originally being developed for washing the pubic area for females, bidet systems have has now been popular among people of all ages and both sexes because it is known to be more hygienic to wash the intimate parts and anus with water instead of paper after relief. In addition, cleansing the pubic/anal regions with water may help to avoid infection and prevent hemorrhoids and other anal disease. Furthermore, it is very effective for women with gynecology diseases. It is also very useful for the elderly or obese people to relieve themselves with great convenience. 
     However, most toilets are incapable of supporting bariatric (i.e., overweight) users. Conventional toilets have a seat designed to receive each user&#39;s weight and distributed onto the toilet when in use. When a bariatric individual using a toilet exceeds the toilet&#39;s support capacity, significant problems may occur. In addition, most toilets with bidet seat cleaning systems are not designed for supporting a bariatric user, either. 
     Many wall-mounted toilets have problems in supporting a bariatric user, thus often being broken off the wall due to over-weight. In addition, floor-mounted toilets are known to collapse after use by a bariatric user. The use of a conventional toilet by a bariatric user often results in serious injuries when the toilet collapses, including, lacerations to the buttocks, thighs, and back. Further, the terrible discomfort and embarrassment after such incident should not be underestimated. 
     In addition, most bariatric seats do not include any bidets systems, because of design incompatibility, in-supportability, and other design and installment problems. However, bariatric users have much greater needs to use the cleaning and drying mechanisms of bidets and bidet seat systems because they often have difficulty in reaching out to their genital or anal area, intimate parts, and perianal regions to clean themselves after the use of toilet. Therefore, there is a need for designing a novel bariatric bidet seat system that can support most bariatric users and help them wash and clean their genital and/or anal area.

     DETAILED DESCRIPTION 
     The present invention generally includes a method and a toilet seat system for bariatric used. The bariatric toilet seat system includes a toilet, a bidet seat assembly, and one or more bidet-support spring mechanisms, a flange support mechanism, a lumbar support mechanism, an arm mechanism, and combinations thereof.  FIG. 1  is a perspective view of one example of a toilet seat system  100  for bariatric users. The toilet seat system  100  includes a toilet  160 , a bidet seat assembly  150 , a lumbar support mechanism  140 , one or more arm mechanisms  130 A,  130 B, one or more bidet-support spring mechanisms  120 , and a flange support mechanism  110  and according to embodiments of the invention. 
       FIG. 2  is an exploded view of the break-down of various parts of one example of the toilet seat system  100 , showing how its parts are connected and assembled together. For example, the toilet seat system  100  includes one toilet  160 , one bidet seat assembly  150 , one flange support mechanism  110  positioned near the bottom back portion of the toilet seat system  100 , and one lumbar support mechanism  140  and a number of fastening means thereon (e.g., one or more screws, pegs, pins, bolts, velcos, nails, adhesives, etc.) for coupling the lumbar support mechanism  140  to the flange support mechanism  110 . 
     In addition, the toilet seat system  100  may include two arm mechanisms  130 A,  130 B and a number of fastening means thereon (e.g., one or more screws, velcos, nails, adhesives, etc.) for coupling the two arm mechanisms  130 A,  130 B to the flange support mechanism  110 . Also, as shown in  FIG. 2 , the toilet seat system  100  may include two bidet-support spring mechanisms  120  and a number of fastening means thereon (e.g., one or more screws, pegs, pins, bolts, velcos, nails, adhesives, etc.) for coupling the two bidet-support spring mechanisms  120  to the flange support mechanism  110  and/or the two arm mechanisms  130 A,  130 B. 
     The toilet seat system  100  is designed such that the bidet seat assembly  150  is positioned atop of the bidet-support spring mechanisms  120  and the toilet  160  to support the body of a human subject, such as a bariatric user who uses the toilet seat system  100  for comfort and sufficient weight support. For the purpose of lifting heavy loads of a bariatric user whose weight is much larger than a regular user (e.g., more than 45 kg or higher, such as more than 80 kg, or between about 100 kg to about 400 kg), the bidet-support spring mechanisms  120  are used to support the bidet seat assembly  150  so that the bidet seat assembly  150  is capable of being flexibly movable in vertical direction and support the weight of a bariatric user when the bariatric user is sitting on top of the bidet seat assembly  150  after its cover is opened (the bidet seat assembly  150  is in a closed-cover position in  FIG. 1  and  FIG. 10A ; see also  FIG. 10B  where the bidet seat assembly  150  is in a opened-cover position). In one example, the one or more bidet-support spring mechanisms  120  are connected by a fastening mean (such as one or more screws, pegs, pins, bolts, nails, velcos, adhesives, etc.) to a bottom of a seat body  240  (shown in  FIG. 10B ) of the bidet seat assembly  150  and provided to support the bidet seat assembly  150 . 
       FIG. 3  shows one example of the lumber support mechanism  140 , having a back support  142  and a support body  144  according to embodiments of the invention. The support body  144  includes one or more holes  146  for coupling with a number of fastening means (e.g., screws  148 , pegs, pins, bolts, nails, velcos, adhesives, etc.) to secure the lumber support mechanism  140  with the flange support mechanism  110 . 
     The back support  142  is shaped curved from top to bottom and from side to side to accommodate the shape of the back of a human user, with many sizes to fit the body width of a human user. The surface of the back portion  142  can be as small as to contact a portion of the back of the user, which makes it possible for a user&#39;s back to contact the support portion of the back support during use. The back support  142  may be made of either plastic, wood, steel, etc. and may be formed suitably in the shape of an oval, a square, a rectangular, etc. The lumbar support mechanism  140  may also have a backward-inclinable function. The elastic movement of the back support  142  can be achieved by the deformability or change in the shape of a curved structure of the support body  144 . 
       FIG. 4  shows one example of the flange support mechanism  110 , having a flange floor support  116 , a support body  114 , and a coupling element  112  according to embodiments of the invention. The coupling element  112  can be used to couple the flange support mechanism  110 , in one example, to the lumber support mechanism  140  or any other suitable support mechanisms via one or more fastening means (e.g., screws  148 , pegs, pins, bolts, nails, velcos, adhesives, etc., as shown in  FIG. 3 ). The flange support mechanism  110  may also include a number of holes (e.g., holes  119 ) or coupling elements (e.g., one or more fastening means, such as screws  118 , pegs, pins, bolts, nails, velcos, adhesives, etc.) for connecting and coupling to the arm mechanisms  130 A,  130 B and the one or more bidet-support spring mechanisms  120 , as shown in  FIG. 4 . 
     In  FIG. 4 , the support body  114  of the flange support mechanism  110  is configured to be mounted to the ground floor via the flange floor support  116  to provide structural support and surround the lower base portion of the toilet  160  of the toile seat system  100 . The support body  114  can be made of metal materials, ceramics, stainless steels or plastic materials, etc. and can be formed in reverse U-shape to surround and support the base portion of the toilet  160 . 
     A plurality of screws  118  or other fastening means, can be used to pass through the holes  119  of the flange floor support  116 , and then when tightened, mounting the flange support mechanism  110  to the ground floor, which can be a concrete, tiled or wood floor, etc. After the flange support mechanism  110  is mounted on the floor, it is then permanently in place and cannot move upwardly. The toilet  160 , being secured to a flange, such as the flange support mechanism  110 , is effectively maintained in a rigid position, and without any tendency of the toilet  160  to loosen on the floor when the flange support mechanism  110  is used together with the toilet  160 . 
     As shown in  FIG. 4 , the coupling element  112  of the flange support mechanism  110  is positioned at the rear side of the support body  114 , preferably near the center of the support body  114 . In one example, the lower portion of the support body  144  of the lumbar support mechanism  140  can be fixed into the coupling element  112  by one ore more fastening means, such as screws  148 . 
     Accordingly, the lumber support mechanism  140 , can be adjusted to a suitable height, such as by providing several holes  146  (as shown in  FIG. 3 ) on the support body  144  and adjusting the length of the support body  144  when it is coupled to the coupling element  112 , prior to tightening the screws  148 , securing the support body  144  to the coupling element  112 , and connecting the lumbar support mechanism  140  to the flange support mechanism  110 . Alternatively, the body of the support body  144  can be divided and separated into matching sections that can be interconnected and used to adjust the length of the body of the support body  144  when coupled to the coupling element  112 . 
     During the set up of the toilet seat system  100 , the support body  144  of the lumber support mechanism  140  is configured and coupled to the back support  142  on one end, and on the other end inserted onto the coupling element  112 . The support body  144  is fixed by fixing screws to the back of the back support  142 . The height (the vertical position) of the back support  142  with respect to the height (the vertical position) of the bidet seat assembly  150  is set to a comfortable position for a user sitting on a bidet seat  230  of the bidet seat assembly  150  by adjusting the length of the insertion of the support body  144  into the coupling element  112 . After the back support  142  has been set at a suitable height, the screws  148  pass through the holes  146  and the support body  144  and are screwed into the flange support mechanism  110 . Prior to using the toilet seat system  100 , all these parts as described are assembled and can be readjusted easily. 
       FIGS. 5A-5B  and  FIG. 6  illustrate examples of the bidet-support spring mechanisms to be coupled to the toilet  160  and the flange support mechanism  110 . One or more bidet-support spring mechanisms  120 , such as two or more bidet-support spring mechanisms  120 A,  120 B, can be used to support the bidet seat assembly  150 . Once assembled and secured to the flange support mechanism  110  via a number of suitable fastening means (e.g., screws  126 , pegs, pins, bolts, nails, velcos, adhesives, etc.), the bidet-support spring mechanisms  120 A,  120 B are positioned near the right and left sides of the bidet seat assembly  150  for supporting the weights of the bidet seat assembly  150 . The toilet  160  may include a toilet bowl  162  and a rim  164 . 
     As shown in  FIGS. 5A-5B , the bidet-support spring mechanisms  120 A,  120 B includes a support body  124 A,  124 B, respectively. The bidet-support spring mechanisms  120 A,  120 B may also include one or more attachment elements  128 A,  128 B wherein their structure are in a shape that can fit into the rim  164  of the toilet seat  160 , e.g., in an “L” shape for attaching themselves to (or positioning themselves onto) the rim  164  of the toilet  160 . The attachment elements  128 A,  128 B may also be used to couple and connect the bidet-support spring mechanisms  120 A,  120 B to the bidet seat assembly  150  via one or more fastening means, holes  129 , screw, pegs, pins, bolts, nails, velcos, adhesives, and/or other coupling elements. The support body  124 A,  124 B may be constructed of any suitable ductile materials, which includes metal materials, structural steel and many alloys of other metals, as characterized by their ability to yield at normal temperatures. The attachment elements  128 A,  128 B of the upper portion of the bidet-support spring mechanism  120  are positioned on each side of the bidet seat assembly  150 . 
     In one embodiment, one or more springs (such as torsion springs  127  as shown in  FIGS. 5A-5B , or other suitable springs) may be coupled to the fastening means (e.g., screws  126 , pegs, pins, bolts, nails, velcos, adhesives, etc., which are used to connect the flange support mechanism  110  and the bidet-support spring mechanisms  120 A,  120 B. A torsion spring is a spring that works by torsion or twisting; that is, a flexible elastic object that stores mechanical energy when it is twisted or in helical structure. When it is twisted, it exerts a force (actually torque) in the opposite direction, proportional to the amount (angle) it is twisted. 
       FIG. 6  is a side view of the toilet seat assembly  150  positioned atop the bidet-support spring mechanism  120  and the toilet  160 , according to one embodiment of the invention, showing the configuration of the support body  124 A in a curved position in an angle “a”, the spring  122 , and the spring  127  so that the bidet-support spring mechanism  120  is adapted to be flexibly moving up and down in a vertical direction “Z”, such that the support body  120  can move flexibly in a vertical plane “A”, according to one or more embodiments of the invention. 
     In another embodiment, the support body  124 A,  124 B are positioned vertically in an angle “α, as compared to a ground plane of the toilet seat system  100  so that the whole structure of the bidet-support spring mechanisms  120 A,  120 B, together with the assistance of the torsion springs  127 , is adapted to swivel flexibly in a vertical plane “A”, leading to the attachment elements  128 A,  128 B to be able to move flexibly up and down in a vertical “Z” position (as shown in  FIG. 6 ), which is advantageous when the attachment elements  128 A,  128 B are attached to the bidet seat assembly  150  such that the bidet seat assembly  150  is then adapted to move flexibly up and down in a vertical “Z” direction in supporting the weight of a bariatric user (or a regular user). 
     In still another embodiment, the bidet-support spring mechanisms  120 A,  120 B additionally include one ore more springs  122  positioned inside the attachment elements  128 A,  128 B. Examples of the springs  122  include compression springs, coiled wires, conventional coils, etc., and can be constructed of metal materials and other suitable elastic materials, such as spring steel, brass, stainless steel materials or other suitable materials. The configuration of the springs  122  are adapted to support and sustain the heavy-weight of a bariatric user when the bariatric user is using the toilet seat system  100  and sitting on tope of the bidet seat assembly  150 . 
     A plurality of spring can be arranged generally parallel to one another and transversely bridge in a uniform manner to provide a spring effect when a downward pressure is applied thereto. The springs  122  are used to provide a relationship of constant load or force over a limited range of deflection. When a person is sitting at the bidet seat assembly  150 , the springs  122  are compressed from their resting positions, and exert an opposing force approximately proportional to the change in their lengths. Usually the effective force (as a resulting of the weight of the user sitting on the bidet seat assembly  150 ) exerted by the springs varies considerably over the entire deflection range. The bidet-support spring mechanism  120  may also minimize the effect of shifting loads applied to the seat area of the bidet seat assembly  150 . 
     In one example, the attachment elements  128 A,  128 B of the bidet-support spring mechanism  120  can touch or contact the upper portion of the rim  164  (as shown in  FIG. 6 ) when a user is using the toilet seat system  100  or when the bidet-seat assembly  150  is in an open-cover position. In another example, the attachment elements  128 A,  128 B of the bidet-support spring mechanism  120 A,  120 B do not touch or contact the upper portion of the rim  164  when a user is not using the toilet seat system or when the bidet-seat assembly  150  is in a closed-cover position. 
     The construction of the support body  124 A,  124 B in a flexible angled position, the use of the torsion springs  127 , the use of the springs  122  within the attachment elements  128 A,  128 B, or the combinations thereof, enables the bidet seat assembly to be able to move flexibly up and down in a vertical position in supporting the weight of a bariatric user (or a regular user). Not wishing to be bound by theory, it is contemplated that the weight of an user sitting on the top of the bidet seat assembly  150  of the toilet seat system  100  of the invention is then evenly distributed to the one or more bidet-support spring mechanisms  120 A,  120 B and, via the bidet-support spring mechanisms  120 A, which is connected to the flange support mechanism  110 ,  120 B; thus the weight is ultimately distributed to the flange support mechanism  110 . Further, the use of the torsion springs  127  and/or the use of the springs  122  help to absorb a portion of the weight of the user, especially for a bariatric user. 
     The bidet-support spring mechanism  120  is accordingly adapted to provide better weight distribution for the toilet seat system  100  and security for a user-friendly and comfortable toilet experience. When a heavy-weight bariatric person is sitting on the toilet seat system  100 , the spring mechanism  120 , being slightly tilted in an “α  angle and with the help of the spring  122  and the torsion spring  127  provides uniform weight pressure and structural support, transmitting via the bidet-support spring mechanism  120  and the flange support mechanism  110  to the ground floor. The bidet-support spring mechanism  120  generally offers firmer support within the seating area and in addition provides a wider weight capability for the toilet seat system  100  to accommodate a regular user to a heavy-weight user. 
       FIGS. 7A-7B  shows examples of the arm mechanisms  130 A,  130 B, respectively, having an armrest  132 A,  132 B, an upper support body  134 A,  134 B, a lower support body,  136 A,  136 B according to one or more embodiments of the invention. Each of the upper support bodies  134 A,  134 B of the arm mechanisms  130 A,  130 B can be connected to the lower support bodies  136 A,  136 B via a fastening element  137 . The type of the fastening element  137  that can be used is not limited, and examples of the fastening element  137  includes pegs, pins, screws, bolts, etc., among others. 
     In  FIG. 7A , the arm mechanism  130 A is a retractable arm mechanism and includes the armrest  132 A, the upper support body  134 A, and the lower support body  136 A. In  FIG. 7B , the arm mechanism  130 B is a retractable arm mechanism and includes the armrest  132 B, the upper support body  134 B, and the lower support body  136 B. In one or more examples, each of the upper support bodies  134 A,  134 B can have a circular or rectangular cross-section with an inner diameter a little bit larger than the outer diameter of each of the lower support bodies  136 A,  136 B, or vice versa. Each of the components and parts of the arm mechanisms  130 A,  130 B can be made of molded plastic, plywood, hard rubber, or even stainless steel. 
     In addition, the use of the upper support bodies  134 A,  134 B, and the lower support bodies,  136 A,  136 B allows the arm mechanisms  130 A,  130 B to be in the form of two or more length and configurations. In a first configuration, the arm mechanisms  130 A,  130 B can be at a full length (also shown in  FIG. 8A ), in which case each of the upper support bodies  134 A,  134 B extends upwardly up to a first terminal point, which may be the highest in vertical “Z” direction. In a second configuration, the arm mechanisms  130 A,  130 B can be at a shortest length (also shown in  FIG. 8B ), in which case each of the upper support bodies  134 A,  134 B extends downwardly to a second terminal point, which may be the lowest in vertical “Z” direction. 
     Accordingly, the upper support bodies  134 A,  134 B form as upward extensions of the lower support bodies,  136 A,  136 B and have a geometric and aesthetic continuity with respect to the lower support bodies,  136 A,  136 B. Each of the fastening elements  137  is fitted onto the upper support body  134 A (or the upper support body  134 B) so that the support bodies of the arm mechanism  130  can be extended to have different length and as a result, the armrest  132 A,  132 B can be adjusted vertically up and down to reach the desired height for different people by loosing and tightening of the fastening element  137  and adjust the upper support bodies,  134 A,  134 B to a different vertical positions, as compared to the positions of the lower support bodies,  136 A,  136 B. 
     Each of the arm mechanisms  130 A,  130 B are secured to a flange  138  or other securing mechanism located on the ground by a number of coupled fastening mechanism, including holes and screws  139 A,  139 B, etc. The fastening elements  139 A,  139 B can be any key hole fasteners, screws, bolts, other connectors or combinations thereof. The arm mechanisms  130 A,  130 B can also be mounted onto the flange support mechanism  110 , as shown in  FIGS. 8A-8B . In one or more examples, the arm mechanisms  130 A,  130 B are mounted onto the flange support mechanism  110 . Once being assembled and secured to the flange support mechanism  110  via a number of suitable fastening means, the one or more arm mechanisms  130 A,  130 B are positioned near the bidet seat assembly  150  for supporting the right and left arms and weights of a bariatric user, e.g., the user  170 , so that the bariatric user can use the bidet seat assembly with ease. 
       FIG. 8A  and  FIG. 8B  provide sides view of two exemplary bariatric toilet seat systems where the armrest  132 A,  132 B of the arm mechanism  130 A,  130 B of the toilet seat system  100  are adapted to be moving up and down in a direction “H”, as shown in  FIG. 8A , and in a direction “I”, as shown in  FIG. 8B , respectively, when the arm mechanisms  130 A,  130 B. In the example of  FIG. 8A , the toilet seat system  100  is not being pressed with a force, or is leveled with an up force. In the example of  FIG. 8B , the toilet seat system  100  is being pressed with a down force, or is leveled with a down force. 
     In one or more embodiment, the upper support bodies  134 A,  134 B and/or the lower support bodies,  136 A may be curved in shape such that the arm mechanism  130 A,  130 B provide better upward and downward springing weight support for the arms of heavy weight users. In addition, the adjustment of the heights of the armrests  132 A,  132 B is performed by sliding the upper support bodies  134 A,  134 B along the lower support bodies  136 A,  136 B. In another embodiments, the heights of the armrests  132 A,  132 B can be at fixed positions by tightening the fastening element  137 . When the adjusting the height of the upper support bodies  134 A,  134 B, the fastening element  137  is loosened until the upper support bodies  134 A,  134 B are sliding along the lower support bodies  136 A,  136 B and being adjusted to a desired height, and then the fastening element  137  can be tightened. 
     As shown in  FIGS. 8A and 8B , the bidet-support spring mechanism  120  is suitable to be positioned under the toilet seat assembly  150  to receive the weight of a user  170 , (e.g., a human a shown in  FIG. 11E ,  FIG. 12C  and  FIG. 13 ) so that the weight of the user  170  is distributed onto the bidet-support spring mechanism  120  and relieved from the bidet seat assembly  150  positioned on top of the toilet  160 . In addition, the bidet seat assembly  150  has large area on its seat portion and is positioned at a height that is ergonomic to the user  170 .

In another example, the medicinal delivery nozzle includes a medicinal liquid inlet being connected to a medicinal storage assembly and adapted for jetting out a medicine-containing solution. In addition, the medicinal storage assembly includes one or more cartridges that store medicines to be applied, and a pressurized pump adapted to pump and deliver the medicines from the one or more cartridges to the medicinal liquid inlet. The medicinal delivery nozzle may further include a medicinal atomizer head adapted to modify a medicine to achieve a consistency that can be applied over a distance and deliver a stream of the medicine to a user. In one aspect, the medicinal delivery nozzle is adapted to deliver one or more medicines across a space to a localized region of a body of a user. One example of the localized region is a perianal region of the body of the user. 
     In still another embodiment, the spray nozzle assembly  330  provided herein includes one or more dynamic steering remote control units that receive an user input to direct the one or more movements of a first motor and one or more second motors and adjust at least one of an angle or a location of the delivery nozzle assembly based on the user input. In still another embodiment, the spray nozzle assembly  330  is remote-controlled and coupled to an base unit and adapted to receive a perianal region of a user. Examples of the base unit include, but are not limiting to, a bidet toilet seat washing system, a bidet medicine delivery seat, a toilet seat assembly, a bedpan, a hydraulic chair, a commode, a hospital bed, among others. In one example, the base unit of the remoted-controlled medicine delivery assembly is a toilet seat assembly, which contains a housing and a base seat. 
     Additional embodiments of the invention provide one or more methods of operating and/or using remote-control units to control the movements of the toilet seat system  100 . The method includes controlling one or more movements of a spray nozzle assembly by one or more dynamic steering remote control units. In one aspect, the one or more movements of a spray nozzle assembly is controlled by one or more dynamic steering remote control units remotely via wireless means or long-wired means. 
     The remote control units  340 ,  342  are adapted to be communicating and directing one or more movements of the one or more assemblies, such as the one or more drying assemblies  350 , the one or more spray nozzle assemblies  330  with one or more spraying nozzles  332 , and one or more medicine delivery assemblies.

       FIGS. 11A-11E  are side views of the toilet seat system  100  where the bidet seat assembly  150  is designed to be movable up and down in the vertical “Z” direction atop of the toilet  160 , according to embodiments of the invention. As shown in  FIG. 11A , when the toilet seat system  100  is not loaded with any force, the bidet seat assembly  150  is atop of the toilet  160  at an angle θ°, such that the spring  122  inside the bidet-support spring mechanism  120  is in its relaxed configuration. There is also no deformation or change in its original curved shape in the support bodies  124 A,  124 B. The angle θ° between the bottom surface of the bidet seat  150  and the top surface of the toilet  160  is larger than zero degree and may be at 5° to 45° or larger. 
     In  FIG. 11A , while the bidet-support spring mechanisms  120 A,  120 B are in its relaxed configuration, the support body  124 A,  124 B of the bidet-support spring mechanisms  120 A,  120 B are curved in an angle α 1 , which extends vertically from zero degree to less than 90°. For example, the angle α 1  may be angled at about 45°. 
     As shown in  FIG. 11B , when the toilet seat system  100  is loaded with a force (e.g., the weight of a bariatric user as exerted as a force “P 2 ”) to push the bidet assembly  150  downwardly. When being loaded with a large enough force such as a heavy weight of a human user, the bidet seat assembly  150  may be moved downwardly to be directly in contact with the top surface of the toilet  160 . As a result, when the bidet assembly  150  is pushed down to be in close contact with the top surface of the toilet  160 , the spring  122  inside the bidet-support spring mechanism  120  is in its tightly compressed configuration and the angle θ° is equal to zero degree. In addition, the support body  124 A,  124 B of the bidet-support spring mechanisms  120 A,  120 B are curved in an angle α 2 , which extends vertically from zero degree to less than 90°. For example, the angle α 2  may be angled at less than about 45°. In one embodiment, the angle α 2  is smaller than the angle α 1  since the bidet-support spring mechanisms  120 A,  120 B are being pushed downwardly. 
     The spring  122  may exert an opposing force (e.g., a force “P 1 ” as shown in  FIG. 11A ) which is in equal and opposite direction of the force (e.g., the direction of the weight of a human user) that&#39;s compressing the spring and thus resisting and supporting the weight of the human user. The opposing force a spring exerts follow Hooke&#39;s law, and is related with spring constant which measures how strong the spring is and the distance the spring is compressed in its compressed configuration/state, different from it equilibrium or rest configuration/state. 
     As shown in  FIG. 11C , when an user of a heavy weight sitting on the bidet seat assembly  150 , it transferred the weight as an applied force (e.g., a force “P 2 ” as shown in  FIG. 11C ) to the bidet-support spring mechanism  120  and produces a stress, thus an opposing force (e.g., a force “P 1 ” as shown in  FIG. 11C ), which then causes the spring  122  to deform and the bidet-support spring mechanism  120  to flexibly bend and support the weight of the user. As deformation of the spring  122  occurs, internal inter-molecular forces arise and oppose the applied force (e.g., a force “P 1 ” as shown in  FIG. 11D ). This is a temporary shape change, which is self-reversing after the force is removed, so that the spring  122  and the bidet-support spring mechanism  120  returns to its original shape. If the spring  122  and the bidet-support spring mechanism  120  are given an overload exceeding a yield point, plastic deformation is caused. This type of deformation is irreversible. While this type of locking system is capable of resisting a heavy weight user (e.g., a weight of approximately 200 pounds or larger, such as 300 pounds or larger or 400 pounds or larger) because of the selected spring and the deformation described hereinabove, this is quite adequate to securely support the weight of an obese user. 
     In  FIG. 11C , the support body  124 A,  124 B of the bidet-support spring mechanisms  120 A,  120 B are curved in an angle α 3 , which extends vertically from zero degree to less than 90°. For example, the angle α 3  may be angled at less than about 45°. In  FIG. 11D , the support body  124 A,  124 B of the bidet-support spring mechanisms  120 A,  120 B are curved in an angle α 4 , which extends vertically from zero degree to less than 90°. For example, the angle α 4  may be angled at about 45°. In one embodiment, the angle  3   2  is smaller than the angle α 4 . 
       FIG. 11E  illustrates one example when a human subject is sitting on top of the bidet seat assembly and using a bariatric bidet toilet seat system with the bidet seat assembly  150 , the bidet-support spring mechanism  120 , and, according to one or more embodiments of the invention. As shown in  FIGS. 11A-11E , the weight of an obese user can be supported by the opposing force (e.g., a force “P 2 ” as shown in  FIG. 11E ) as exerted by the spring  122  and the bidet-support spring mechanism  120  to support the user sitting atop the bidet seat assembly  150 . In addition, a portion of the applied force exerted by the weight of an obese user can also be supported by the lumber support mechanism  140  once the obese user is in contact with the lumber support mechanism  140 . 
       FIGS. 12A-12C  are side view of examples of a bariatric bidet toilet seat system (e.g., the toilet seat system  100 ) having the lumber support mechanism  140 , and the bidet seat assembly  150 , where the seat cover  210  of the bidet seat assembly  150  is closed, as shown in  FIG. 12A , or opened, as shown in  FIG. 12B , and can be pressed against a back support of the lumber support mechanism  140  so that the back support of the lumber support mechanism  140  is in a sit-down “S 1 ” position, according to one or more embodiments of the invention. When the bidet toilet system  100  is not used, the seat cover  210  is closed to cover the base  240 . When the bidet seat assembly  150  is not loaded with a force, there is no deformation of the spring  122 , and the spring  122  is in its equilibrium position. There is also no deformation or change in the curved shape of the support bodies  124 A,  124 B and the lumbar support mechanism  140 . During operation, the seat cover  210  can be opened and positioned upwardly and a bariatric user can sit down on the top surface of the bidet seat  230  and use and operate the bidet seat assembly  150 . As the user is sit down, each or the combination of the compression of the spring  122 , and the arched deformation of the shape and mechanical strength of the support bodies  124 A,  124 B and the lumbar support mechanism  140  helps to support the weight of the bariatric user. 
       FIG. 12C  is a side view of another example of the bidet toilet seat system  100 , where a cover of the bidet seat assembly  150  is opened and a bariatric user is sitting down and positioned atop of the bidet seat assembly. In this example, the bariatric user is able to comfortably lean backward against the back support of the lumber support mechanism  140  so that the back support of the lumber support mechanism  140  is in a sit-down “S 2 ” position, according to one or more embodiments of the invention. The lumber support mechanism  140 , the bidet support spring mechanism  120  and the spring  122  can functions together to support the heavy weight of a bariatric user. Prolonged sitting in a bidet seat system is frequently attended by discomfort in the back of the user. Actually, it commonly is recognized that rapid tiredness is encountered during sitting. The region of discomfort varies from persons to persons. This discomfort may derive from a particular configuration, construction and the back support of a seat system being used. The toilet seat system  100  with the lumbar support mechanism  140  light in weight, pleasing in appearance, and readily secured or adjusted provides a direct and effective manner to closely satisfy the back support requirements of each individual user. 
       FIG. 13  illustrates one example when the bariatric user is getting up after sitting atop of the bidet seat assembly  150  and using a toilet bariatric bidet toilet seat system. In this example, the bariatric user can use one or both of his hands to exert pressure and weight and press down the armrests  132 A,  132 B of the arm mechanisms  130 A,  130 B, such that the weight of the bariatric user is supported by the arched shape and mechanical strength of the arm mechanisms  130 A,  130 B, which ultimately is supported by the ground where the arm mechanisms  130 A,  130 B are connected to. 
     While being seated on the toilet seat system  100  equipped with the arm mechanisms  130 A,  130 B, the human user can rest his or her arms on the armrests  132 A,  132 B comfortably, and when standing up from the bidet seat system  100 , the human subject can press his or her hands against the armrests  132 A,  132 B, exerting his or her weight on the armrest  132 A,  132 B, and being supporting for an opposing force, as shown in  FIG. 13  as a force, “J”, being the mechanical strength of the arm mechanisms  130 A,  130 B and ground floor support. The human user can prop his or her upper body up with the help of his or her hands in such a way as to stand up more easily. The toilet seat system  100  equipped with adjustable armrests  132 A,  132 B described herein provides more comfortable and convenient user experience to each user. 
     Accordingly, the invention provides the toilet seat system  100  for supporting a body of a bariatric user, where one or more bidet-support spring mechanisms  120  are positioned adjacent to a toilet, and the bidet seat assembly  150  are positioned atop the one or more bidet-support spring mechanisms  120  and the toilet  160  to support the body and weight of the human user. The one or more bidet-support spring mechanisms  120  are connected to a bottom of a seat body  232  of the bidet seat assembly  150  and provided to support the bidet seat assembly  150  and thus the weight of the human user sitting atop the bidet seat assembly  150  so that the bidet seat assembly is capable of being flexibly movable in vertical direction. In one embodiment, the bidet seat assembly  150  includes the spray nozzle assembly  330  for jetting out water at a temperature ranging from between room temperature to about 90° C. In addition, the flange support mechanism  110  is connected to the one or more bidet-support spring mechanisms  120  and being secured to the floor where the toilet seat system  100  is positioned thereon. The bariatric toilet seat system can be automated with a user-friendly control system built inside the bariatric toilet seat system and controlled by an attached control unit or a remote control. Methods of forming the bariatric toilet seat system and methods using the bariatric toilet seat system are also disclosed. 
     While the foregoing is directed to embodiments of the present invention, other and further embodiments of the invention may be devised without departing from the basic scope thereof, and the scope thereof is determined by the claims that follow.
