Description




TECHNICAL FIELD




The present invention relates to an outfitting system for a kayak that includes hip pads adjustable by a user seated in the kayak cockpit.




BACKGROUND OF THE INVENTION




A kayak, whether designed for use in whitewater, the sea, or flat water, may includes various items of outfitting configured to improve the comfort and fit of the kayak. For example, a whitewater kayak may include a contoured seat to position and support the user within the cockpit, a back band to support the lower back of the user, and various types of thigh braces, foot braces and hip braces against which the user may exert force to control the boat, and which may help to hold the user in the boat.




To improve the performance of a kayak, a user may modify factory-installed outfitting to fit the user's body more precisely. For example, customized hip pads may be attached to the hip braces. These hip pads may help to hold the user's hips more snugly in the cockpit so that movements of the user's hips are transferred to the kayak more precisely and efficiently. Hip pads are typically formed from closed-cell foam, and are attached to the hip braces with a strong adhesive, such as contact cement, to prevent the pads from shifting or detaching during use.




Where a user anticipates running difficult whitewater or performing advanced freestyle moves, the user may install very snug hip pads for improved boat control. However, a great deal of time may be spent paddling easier water between difficult stretches, or sitting in the kayak in the relative calm of an eddy between freestyle sessions. In these situations, the snug hip pads may cause discomfort. However, because the pads are glued to the hip braces and have a fixed shape, it may be difficult or impossible to loosen the hip pads between rapids or freestyle sessions. Likewise, where a looser, more comfortable fit in a kayak is desired, it may be difficult to increase the snugness of the hip pads for periods when more boat control is desired.




SUMMARY OF THE INVENTION




One aspect of the present invention provides a personal watercraft. The personal watercraft includes a cockpit configured to be occupied by a user when using the watercraft; and an item of outfitting coupled to the watercraft at a location at least partially inside of the cockpit, the item of outfitting being configured to help secure the user in the cockpit. The item of outfitting includes a shaped portion configured to contact the user, and a fluid-holding bladder disposed adjacent the shaped portion, wherein the fluid-holding bladder may be selectively filled with a fluid to push the shaped portion against the user to secure the user in the cockpit more tightly.




Another aspect of the present invention provides a hip pad system for a kayak, the kayak including a cockpit having a hip brace disposed therein. The hip pad system includes a hip pad configured to be attached to the hip brace, the hip pad having a shaped portion configured to contact a user seated in the cockpit and a fluid-holding bladder disposed adjacent the shaped portion. The hip pad system also includes a fluid pump, and a fluid supply line disposed between the fluid pump and the fluid-holding bladder, wherein the fluid pump is operable by the user to selectively pump a fluid into the fluid-holding bladder to push the shaped portion against the user.




Yet another aspect of the present invention provides an outfitting system for a personal watercraft, the personal watercraft including a cockpit having a seat with opposing sides, a first hip brace coupled with one opposing side of the seat, and a second hip brace coupled with the other opposing side of the seat. The outfitting system includes a first hip pad configured to be coupled with the first hip brace, the first hip pad having a first fluid-holding bladder; a second hip pad configured to be coupled with the second hip brace, the second hip pad having a second fluid-holding bladder; a fluid transport line configured to connect the first fluid-holding bladder and the second fluid-holding bladder; and a fluid pump connected to the fluid transport line. The fluid pump is configured to be operable by the user while sitting in the cockpit to allow the user to selectively add and remove fluid from the fluid bladders.

DETAILED DESCRIPTION OF THE DEPICTED EMBODIMENT





FIG. 1

shows, generally at


10


, a whitewater kayak having a cockpit


12


equipped with a seat


14


. While the depicted embodiment is shown described in the context of a whitewater kayak, it will be understood that an outfitting system according to the present invention may be used in any suitable type of kayak, an open or decked canoe, or any other suitable type of personal watercraft.





FIG. 2

shows seat


14


in more detail. Seat


14


includes an upturned hip brace


16


positioned on each side of the seat in a location adjacent to the hips of a user sitting in seat


14


. To increase the accuracy of the fit of seat


14


and hip brace


16


on a user, seat


14


is equipped with a first exemplary embodiment of an outfitting system according to the present invention. The outfitting system includes a hip pad


18


attached to each hip brace


16


. Hip pads


18


are configured fit snugly against the hips of a user sitting in seat


14


to permit more precise control of the kayak. To allow the tightness of the fit to be adjusted, each hip pad


18


is connected to a pump


20


via an air supply line


22


. Pump


20


and air supply line


22


are configured to allow an air bladder contained within the hip pad to be selectively filled with air when a tighter fit is desired, and to be drained of air when a looser fit is desired. In this manner, a user may quickly, easily and reversibly loosen or tighten the fit of hip pads


18


at any desired time, while remaining seated in cockpit


12


of kayak


10


. Furthermore, the fit of hip pads


18


may be adjusted extremely precisely, as the position of each hip pad is infinitely adjustable within its adjustability range.




Any suitable pumping device may be used to expand the bladder within each hip pad


18


. In the depicted embodiment, pump


20


takes the form of a squeeze bulb such as that commonly used to inflate a blood pressure cuff. Pump


20


also may include a pressure release valve


24


operable to release air from hip pads


18


. While the depicted pressure release valve


24


is integral with pump


20


, it will be appreciated that the pressure release valve may be positioned at any other desired location on fluid supply line


22


, or on either of hip pads


18


. Additionally, while pump


20


is depicted as a squeeze bulb, any other suitable pumping device, or even a compressed gas source, may be used to expand hip pads


18


. Furthermore, it will be appreciated that the pump may be configured to transport any other suitable fluid besides air, whether a liquid or gas, to expand hip pads


18


.




Air supply line


22


may have any design suitable for transporting air (or other fluid) between hip pads


18


, pump


20


and pressure release valve


24


. In the depicted embodiment, air supply line


22


includes a first tube segment


26


connecting pump


20


and pressure release valve


24


to a T-connector


28


, and a pair of second tubes segments


30




a, b


that extend from the T-connector to hip pads


18


. Tube segments


26


,


30




a


and


30




b


are positioned mostly underneath seat


14


in the depicted embodiment, with the exception of a small length of first tube segment


26


that extends out of a hole


32


formed in seat


14


. This allows pump


20


to be positioned approximately between and below a user's legs, and thus within easy reach of a user seated in cockpit


12


. Furthermore, first tube segment


26


may include some extra length so that a user may pull pump


20


a small distance away from seat


14


to facilitate use of the pump.




Positioning the tubes of air supply line


22


beneath seat


14


may help to prevent the tubes from being damaged during use, or when a user is entering or exiting cockpit


12


. However, it will be appreciated that the tubes of air supply line


22


may also be positioned at any other desired location within cockpit


12


.




Air supply line


22


may also be formed from any suitable components. For example, tube segments


26


,


30




a


and


30




b


may be formed from tubing with a relatively small diameter, as small diameter tubing may help slow the shifting of air between the two hip pads


18


during use. One example of a suitable inner diameter for tube segments


26


,


30




a


and


30




b


is {fraction (3/16)}″, although tubes with either a larger or smaller inner diameter may also be used.




As mentioned above, fluid supply line


22


is configured to deliver air (or other fluid) to a bladder contained within each hip pad


18


.

FIG. 3

shows the construction of hip pad


18


in more detail. Hip pad


18


includes a relatively rigid shaped portion


40


, and an air bladder


42


positioned behind the shaped portion. As a user pumps air into air bladder


42


, the air bladder expands and pushes shaped portion


40


more firmly against the hip of the user. Shaped portion


40


is configured to retain its shape regardless of the pressure exerted by air bladder


42


, and thus to fit the hip of a user in the cockpit regardless of the amount of air in the air bladder.




Shaped portion


40


and air bladder


42


may be held in position relative to one another in any suitable manner. In the depicted embodiment, shaped portion


40


and air bladder


42


are each contained within an outer cover


44


. Outer cover


44


may be formed from any suitable material. Suitable materials include, but are not limited to, elastic fabrics, such as spandex or a blended spandex fabric. Outer cover


44


may be permanently secured to shaped portion


40


and/or air bladder


42


, for example, by sewing or gluing, or both the shaped portion and air bladder may be removable from outer cover. Where outer cover


44


is permanently secured to shaped portion


40


, a pocket (not shown) may be provided in the back of outer cover


44


to accept the insertion of bladder


42


.




Shaped portion


40


may have any suitable configuration. In the depicted embodiment, shaped portion


40


is configured to conform to the curvature of a user's hip and upper thigh. Thus, shaped portion


40


includes a lower portion


46


configured to push laterally against the user's hip to prevent side-to-side motion in the cockpit, and an upper portion


48


that curves at least partially over the top of the user's hip to help hold the user down against seat


14


.




Likewise, shaped portion


40


may be formed from any suitable material or materials. Suitable materials include those that are able to generally retain shape under stress, that are lightweight, and/or that are comfortable against a user's body. Examples of suitable materials include, but are not limited to, closed-cell foams, such as a thermoformed EVA foam. Another suitable alternative may be to form shaped portion


40


from a rigid or semi-rigid plastic material covered with a layer of padding.





FIGS. 4 and 5

show bladder


42


in more detail. Bladder


42


includes an air chamber


50


formed from a material with a low permeability to air, and with sufficient flexibility to allow the volume of the air chamber to collapse and expand as needed. One example of a suitable material for the construction of air chamber


50


is polyurethane. In the depicted embodiment, air chamber


50


is formed from an outer piece


52


of polyurethane (or other suitable material) bonded to an inner piece


54


of polyurethane along its perimeter. Air supply line


22


extends into air chamber


50


, and is bonded to the air chamber where it enters the air chamber. Air supply line


22


may include a flared end portion


56


to provide more surface area for forming a stronger bond to inner piece


54


of air chamber


50


.




Outer piece


52


and inner piece


54


of air chamber


50


may be bonded together in any suitable manner to form air chamber


50


. For example, outer piece


52


and inner piece


54


may be bonded together with a strong adhesive that is impermeable to the gasses in air. Alternatively, where outer piece


52


and inner piece


54


are formed of a polymer such as polyurethane, they may be bonded together by a suitable plastic welding technique, such as RF welding. The use of RF welding may be advantageous, as it may create a seam with the same strength and tear resistance as the bulk portions of the polyurethane.




During use, a user may exert a great deal of force against hip pads


18


in a very dynamic manner. For example, the user may be exerting force upwardly against upper portion


48


of hip pad


18


at one instant, and then against lower portion


46


of the hip pad at the next instant. Where air is able to flow freely in air chamber


50


between upper portion


48


and lower portion


46


of hip pad


18


, the fit of the hip pad against the user may feel somewhat inconsistent and less secure as air flows within air chamber


50


in response to the user's motions. Therefore, air chamber


50


may also include one or more baffles configured to slow the flow of air between the lower portion of the air chamber, indicated at


58


, and the upper portion of the air chamber, indicated at


60


.




Any suitable structure for slowing the flow of air between lower portion


58


and upper portion


60


of air chamber


50


may be used as a baffle. In the depicted embodiment, the baffle, indicated at


62


, takes the form of a region in the center of air chamber


50


in which outer piece


52


and inner piece


54


of air bladder


50


are bonded to one another. This leaves only a pair of relatively narrow channels


64




a


and


64




b


through which air may flow between the lower portion


58


and upper portion


60


of air chamber


50


. This may help to prevent the rapid shift of air within air chamber


50


during use, and thus may help to increase the stability and consistency of fit of hip pads


18


against the user.




As described above, outer piece


52


and inner piece


54


of air chamber


50


are typically formed from a flexible material. To hold air chamber


50


in the correct shape, and to provide a structure with which hip pad


18


may be attached to hip brace


16


, bladder


42


may also include a rigid support member


64


. Support member


64


may be attached to the other components of bladder


42


in any desired manner. In the depicted embodiment, support member


64


is secured to the other components of bladder


42


by an additional backing piece


66


of material that is bonded to the perimeters of outer piece


52


and inner piece


54


of air chamber


50


to enclose the support member completely. Support member


64


may be formed from any suitable material. One example of a suitable material is rubberized polystyrene, as rubberized polystyrene is stiff, strong, lightweight, and does not absorb water. Likewise, backing piece


66


may also be formed from any suitable material. It may be desirable to form backing piece


66


from the same material as outer piece


52


and inner piece


54


of air chamber


50


to permit backing piece


66


to be bonded strongly to the other pieces via RF welding.




Hip pad


18


may be attached to hip brace


16


in any suitable manner. For example, hip pad


18


may be attached to hip brace


16


with a suitable adhesive, such as contact cement, or with one or more rivets. However, in the depicted embodiment, hip pad


18


includes a pair of threaded bolts


68


for attaching the hip pad to hip brace


16


. The use of bolts to attach hip pad


18


to hip brace


16


may allow the position of hip pad


18


within cockpit to be adjusted, as described in more detail below. While the depicted hip pad includes two bolts for attaching the pad to hip brace


16


, either more or fewer bolts may be used if desired.





FIG. 6

shows a simple schematic illustrating the adjustability of hip pads


18


. Where bladder


42


is drained of air, hip pads


18


are positioned in a looser configuration, closer to the sides of cockpit


12


as indicated in solid lines. On the other hand, where bladder


42


is filled with air, hip pads


18


are positioned in a tighter configuration, further from the sides of cockpit


12


, as indicated in dashed lines at


18


′. It will be appreciated that hip pads


18


are infinitely adjustable between the fully inflated and fully deflated configurations of bladder


42


, and thus may be positioned at any location within the range of possible adjustability, typically 1-3 inches at each hip pad, although the hip pads may have a greater or lesser range of adjustability if desired.





FIGS. 6 and 7

also show a vertical adjustment capability of hip pad


18


, as indicated at


18


″. As described above, each hip pad includes a pair of bolts


68


with which the hip pads are attached to hip braces


16


. In turn, each hip brace


16


may include elongate slots, shown at


72


in

FIG. 7

, configured to receive bolts


68


. The use of elongate slots


72


may allow the position of hip pad


18


relative to hip brace


16


to be adjusted by simply moving bolts


68


along the slots until hip pad


18


is in a desired position, and then fixing the bolts in the slots with nuts


70


. Slots


72


may be oriented in any desired direction, and may have any suitable length. For example, the slots may be oriented in a true vertical orientation, or may be oriented at an angle from the vertical, for example, 30 degrees forward from the vertical, as shown in FIG.


7


. Additionally, where hip brace


18


includes two bolts


68


for attaching the hip pad to hip brace


16


, the pitch of the hip pad may also be varied by loosening and shifting only one bolt while holding the other bolt fixed.
