It is not an admission that any of the information provided herein is prior art or relevant to the presently claimed invention, or that any publication specifically or implicitly referenced is prior art.
[0003] Inflating cushioning is a very trending feature that vehicle companies provide along with vehicles nowadays. The inflating cushioning is mostly used in the backrest, headrest, and seat cushion of the vehicle seats such that it comes in contact with the lumbar, neck, and thigh region of the user sitting on the vehicle seat. Mostly this inflatable cushioning comes with a pneumatic pumping system having bulky arrangement and with more number of components.
[0004] Besides, the use of existing inflatable cushioning systems that are used for vehicle seats are cumbersome and thus not feasible and are also highly inefficient and expensive to be used in the neck support area and/or thigh support area, and/or lumbar support area of the automobile at the same time, as a separate actuating knob for selection and for pumping is required in the pneumatic pumping system for each of the cushioning systems, which are required to be installed separately for each of the different support components of the seat, thereby increasing the complexity and bulkiness.
[0005] There is, therefore, a need for an improved inflatable cushioning system for a vehicle seat, which can be configured with the vehicle seat at different locations like the neck support area and/or thigh support area of the seat, and which allows simple procedure for inflation/deflation of the cushions at the neck support and/or thigh support area of the seat using a single and easily operable selection switch and pumping system. Further, there is a need for a pneumatic pumping system that allows selective fluid connection between the pump and the inflatable cushion(s) of the vehicle seat using a single and easily operable selection switch.

SUMMARY
[0015] The present disclosure relates to the field of automobile cushioning systems. More particularly the present disclosure relates to a pneumatic pumping system for an inflatable cushioning system that is used for vehicle seat components like neck support, seat bolster, lumbar support, and the like.
[0016] An aspect of the present disclosure pertains to a pneumatic pumping system for an automobile seat, which allows selective inflation of one or more inflatable cushions for example at the neck support and/or thigh support area of an automobile seat using a single and easily operable selection switch and pump. The inflatable cushions can include an inflatable bladder covered with fabric. Further, the inflatable cushions can be a composite material comprising an inflatable layer and other fabrics. The pumping system comprises a housing accommodating a pump. The pump is adapted to be fluidically coupled to a first inflatable cushion which may be arranged at a neck support area of the seat and/or a second inflatable cushion which may be arranged at the thigh support area (bolster) of the seat. More particularly, the pump is fluidically coupled to a first inflatable cushion and/or a second inflatable cushion via a valve, preferably a multi-way valve including a plurality of openings/outlets, of which one opening/outlet is fluidly coupled to the pump and other opening (s)/outlet(s) are fluidly coupled to the first inflatable cushion and/or the second inflatable cushion, preferably by a conduit.
[0017] The pumping system includes a pumping knob accessible from the front of the pumping system or a housing of the pump. Actuation of the pumping knob enables the pump to supply fluid like air into the first inflatable cushion, and/or the second inflatable cushion, thereby inflating the first inflatable cushion and/or the second inflatable cushion upon actuating the pumping knob for a predefined number of times.
[0018] The pneumatic pumping system further includes a selector switch rotatably configured on the housing and accessible from the front of the housing. The selector switch is a rotating disk with a center cavity, having the pumping knob disposed of in the center cavity, which makes the overall pneumatic pumping system compact. The selector switch comprises a plate with a cam slot, wherein rotation of the disk enables the selection of any of the outlets of the valve, which results in fluidic coupling of the pump with the first inflatable cushion, and/or the second inflatable cushion. Accordingly, the actuation of the pumping knob after the selection of the desired outlets of the valve enables inflation of the selected inflatable cushion.
[0019] Another aspect of the present disclosure pertains to an improved pneumatic pumping system for a vehicle seat that may be configured with a first inflatable cushion and/or second inflatable cushion, which may be arranged at the neck support and/or thigh support area of the seat respectively, and which allows selective inflation of the cushion(s) of the seat using a single and easily operable selection switch and pumping system. Further, it also enables selective deflation of the cushion(s) and fluid connection of the cushion(s) with a pump of the pumping system using a single and easily operable selection switch. The pumping system includes a housing accommodating a pump adapted to be fluidically coupled to a first inflatable cushion and/or a second inflatable cushion. The pump enables inflation, on actuation of a pumping knob associated with the pump, of the first inflatable cushion and/or the second inflatable cushion. The pumping system further includes a selector switch rotatably configured on the housing to select fluid connection between the pump and the first inflatable cushion and/or between the pump and the second inflatable cushion and to deflate the first inflatable cushion and/or the second inflatable cushion.
[0020] In an aspect, the pump is fluidically coupled to a first inflatable cushion and/or a second inflatable cushion via a valve, preferably a multi-way valve including a plurality of outlets, of which one opening/outlet is fluidly coupled to the pump and other opening(s)/outlet(s) are fluidly coupled to the first inflatable cushion and/or the second inflatable cushion, preferably by a conduit. In an aspect, the selector switch is a rotating disk comprising a plate with a cam slot, wherein rotation of the disk enables selection of any of the plurality of outlets of the valve, which results in fluidic coupling of the pump with the first inflatable cushion and/or the second inflatable cushion
[0021] In an aspect, the valve includes a selector lever adapted to move within the cam slot of the plate upon rotation of the selection switch such that, the pump is fluidly coupled with the first inflatable cushion and/or the second inflatable cushion.
[0022] In an aspect, bleed ports are arranged on the housing and fluidly connectable to the first inflatable cushion and/or second inflatable cushion, preferably by a conduit such that a pin of the selector switch actuates the deflation of the cushion when the selector switch rotates.
[0023] In an aspect, rotation of the selector switch to a first position, in a first direction till a first pre-defined degree from a neutral position, may fluidically couple the first inflatable cushion to the pump. Further, rotation of the selector switch to a second position, in a second direction till a second pre-defined degree from the neutral position, may fluidically couple the second inflatable cushion to the pump. Wherein in one of the scenarios, in the neutral position of the switch, the pump is not fluidly connected to the inflatable cushion(s), thus avoiding any unintentional inflation/deflation of the cushion.
[0024] In another aspect, rotation of the selector switch to a first position, in a first direction till a first pre-defined degree from a second position, may fluidically couple the first inflatable cushion to the pump. Further, rotation of the selector switch to the second position, in a second direction till a second pre-defined degree from the first position, may fluidically couple the second inflatable cushion to the pump
[0025] In an aspect, rotation of the rotary selector switch beyond the first position in the first direction facilitates deflating the first inflatable cushion. Further, rotation of the selector switch beyond the second position in the second direction facilitates deflating the second inflatable cushion.
[0026] In an aspect, the selector switch may include a biasing means for retracting the selector switch to the first position, or the second position upon rotating the selector switch beyond the first position, or the second position, respectively.
[0027] Thus, the present invention allows selective inflation of the cushions at the neck support and thigh support area of a vehicle seat using a single and easily operable selection switch and a single pump only

[0049] Referring to FIGs. 1 to 4, the proposed pneumatic pumping system for a vehicle seat 100 can include a housing that can be configured to accommodate a pump 120. The pump 120 can be fluidically configured with a first inflatable cushion 102 that can be configured at a neck portion of the vehicle seat 100, and a second inflatable cushion 104 that can be configured at the thigh support area (bolster) of the vehicle seat 100. The inflatable cushions 102 and 104 can include an inflatable bladder covered with fabric.
[0050] In an embodiment, the pump 120 can include an air outlet/opening 120-1 that can be fluidically coupled with a direction control valve 105 (also referred to as a valve 105, herein) that can be a multi-way valve having a plurality of openings 106-1, 106-2, 106-3 (collectively referred as openings 106, and individually referred as the opening 106). For instance, the air opening 120-1 of the pump 120 can be fluidically configured with a first opening 106-1 among the plurality of openings 106. Further, a second opening 106-2 among the plurality of openings 106 can be fluidically coupled with the first inflatable cushion 102 and a third opening 106-3 among the plurality of openings 106 can be configured with the second inflatable cushion 104.
[0051] Further, the pneumatic pumping system can include a selector switch 112 having a center cavity 112-1 configured with the housing. The selector switch 112 can be a rotating disk having a plate with a cam slot 114. The selector switch can be rotated to establish a fluidic path between the second opening 106-2 and the first inflatable cushion 102 and a fluidic path between the third opening 106-3 and the second inflatable cushion 104. This can facilitate fluidic coupling of the pump 120 with any or combination of the first inflatable cushion 102 and the second inflatable cushion 104. The pumping system can include a pumping knob 110 configured in the center cavity 112-1. The pump 120 upon actuation/pressing can enable the pumping of air into any of the selected cushions 102 or 104. As the pumping knob 110 is configured in the center cavity 112-1 of the selector switch 112, the overall system can be kept compact.
[0052] In an embodiment, the valve 105 can include a selector lever 105-1 that can be adapted to move within the cam slot 114 upon rotation of the switch 112 such with rotation of the switch 112, the pump 120 can be fluidly coupled with the first inflatable cushion 102 and/or the second inflatable cushion 104. The air pump 120 can include the pumping knob 110 accessible from the front of the pump 120 and which can be actuated or pressed by a user, resulting in the pumping of air into any of the first inflatable cushion 102, and the second inflatable cushion 104.
[0053] In an embodiment, the cam slot 114 can be a Z shaped slot. The selector switch 112 can be adapted to be rotated or moved between a neutral position, a first position, and a second position. In an embodiment, as shown in FIG. 2A, at the neutral position, both the first inflatable cushion 102 and the second inflatable cushion 104 can be fluidically decoupled from the pump 120. In another embodiment, at the neutral position, both the first inflatable cushion 102 and the second inflatable cushion 104 can be fluidically coupled with the pump 120. In an implementation, as shown in FIG. 2B, the rotation of the selector switch 112 to the first position, in a first direction (clockwise) till a first pre-defined degree (90 degrees) from a neutral position (shown in FIG. 2A), can fluidically couple only the first inflatable cushion 102 to the pump 120. This can facilitate inflation of the first inflatable cushion 102 by the pump 120.
[0054] Further, as shown in FIG. 2C, the rotation of the selector switch 112 to the second position, in a second direction (anticlockwise) till a second pre-defined degree (90 degrees) from the neutral position (shown in FIG. 2A), can fluidically couple only the second inflatable cushion (104) to the pump (120). This can facilitate inflation of the first inflatable cushion by the pump 120.
[0055] In another implementation, rotation of the rotary selector switch 112 beyond the first position (by an angle of (??)) in the clockwise direction can facilitate deflating the first inflatable cushion 104, and rotation of the rotary selector switch 112 beyond the second position (by an angle of (??)) in the anti-clockwise direction can facilitate deflating the second inflatable cushion 104. In an embodiment, a bleed port 118 can be configured on the housing as shown in FIGs. 3A-3B. The bleed port 118 can be fluidically coupled to the first inflatable cushion 102 and/or second inflatable cushion 104, via a conduit such that a pin 119 of the selector switch 112 can actuate the deflation of the first inflatable cushion 102 and/or second inflatable cushion 104 when the selector switch 112 rotates.
[0056] Referring to FIG. 2A, both the first inflatable cushion 102 and the second inflatable cushion 104 are deflated and the selector switch 112 is at a neutral position. Referring to FIG. 2B, the selector switch 112 is at the first position after rotating the selector switch 114 in the clockwise direction for facilitating inflation of the first inflatable cushion 102. Referring to FIG. 2C, the selector switch 112 is at the second position after rotating the selector switch in the anti-clockwise direction for facilitating inflation of the first inflatable cushion 104.
[0057] In another embodiment, the selector switch 112 can include a biasing means for retracting the selector switch 112 to the first position, or the second position upon rotating the selector switch 112 beyond the first position or the second position, respectively. In an implementation, the first inflating cushion 102 can be deflated by a user by keeping the selector switch 112 rotated beyond the first position (by an angle of (??)) in the clockwise direction. Further, once the first inflating cushion 102 is deflated, the user can leave the selector switch 112, which can automatically retract back to the first position because of the biasing means. In another implementation, the second inflating cushion 104 can be deflated by the user by keeping the selector switch 112 rotated beyond the second position (by an angle of (??)) in the anti-clockwise direction. Further, once the second inflating cushion 104 is deflated, the user can leave the selector switch 112, which can automatically retract back to the second position because of the biasing means.
[0058] As illustrated in FIGs. 3A to 4, the selector switch 112 can be disposed of around the pumping knob 110. The selector switch 112 can be operatively configured with the first inflatable cushion 102 and the second inflatable cushion 104 through the cam with slot 114. The first inflatable cushion 102 and the second inflatable cushion 104 can be fluidically coupled with the air outlets 106-2 and 106-3, respectively.
[0059] In an embodiment, once the selector switch 112 is rotated to the first position or the second position, the corresponding outlets 106-2 or 106-3 of the valve 105 can be opened by the selector switch 112, and the air can be pumped into the corresponding inflatable cushion through the valve. Once the pumping knob 110 is pressed, air can be pumped into the selected inflatable cushions (102 or 104), however, while releasing the knob 110, the air pumping out of the air from the selected inflatable cushions (102 or 104) is restricted by reverse flow control valves 116-1 or 116-2.
[0060] Thus, the proposed inflatable cushioning system and pneumatic pumping system can be easily configured with the neck support and thigh support area of the seat at the same time, and which also allows selective inflation of the cushions at the neck support and thigh support area of the seat using a single and easily operable selection switch and a single pimp only. Besides, the proposed pneumatic pumping system does not require any electric power to function, thereby keeping it simple, easy to use, and cost-effective at the same time since no complex electronic components are used. Moreover, the proposed pneumatic pumping system and cushioning system require less maintenance cost since no costly electronic components are used. The durability is also more compared to existing systems as the proposed system is manual and the reliability of the whole cushioning system is not compromised due to complex electronic and electrical circuits.
[0061] Moreover, in interpreting the specification, all terms should be interpreted in the broadest possible manner consistent with the context. In particular, the terms “comprises” and “comprising” should be interpreted as referring to elements, components, or steps in a non-exclusive manner, indicating that the referenced elements, components, or steps may be present, utilized, or combined with other elements, components, or steps that are not expressly referenced. Where the specification claims refer to at least one of something selected from the group consisting of A, B, C ….and N, the text should be interpreted as requiring only one element from the group, not A plus N, or B plus N, etc.
[0062] While the foregoing describes various embodiments of the invention, other and further embodiments of the invention may be devised without departing from the basic scope thereof.
