The present invention is directed to a motorcycle seat assembly and more particularly to an adjustable motorcycle seat assembly with a mounting arrangement configured to provide ergonomic adjustment of seat position.
Motorcycle riders come in all shapes and sizes but motorcycle seats typically are fixed in place offering virtually no adjustability. As a result of motorcycle seats not being very adjustable, if at all, most motorcycles have seats designed to try to fit as many different people as possible but which are not designed to fit the tallest and shortest riders. Even such attempts to try to design motorcycle seats to fit as many people as possible have fallen far short as many riders having a height or size falling within the intended fit range find the seating less than desirable. What ends up happening as a result is that prospective motorcycle purchasers' end up trying a wide variety of motorcycles having different types, sizes and shapes in an attempt to find a motorcycle that fits the rider. Even then, for those that are smaller, shorter, taller and heavier, it can be an exercise in futility often ending up buying a motorcycle with seating that is not very comfortable though more comfortable than anything else they evaluated.
What is needed is a motorcycle seat assembly and mounting arrangement that permits seat adjustment sufficient to fit the motorcycle to the rider instead of the other way around.
The present invention is directed to an ergonomic position-adjustable vehicle seat assembly particularly well suited for use in vehicles having fore-aft operator and passenger seating that is constructed and arranged to enable seat position adjustment of one or both of the operator seating and passenger seating to increase seat occupant comfort as well as provide enhanced operator ergonomics. A preferred ergonomic position-adjustable vehicle seat assembly is configured for use with motorcycles and constructed and arranged to enable at least an operator seat or driver seat to be position-adjustable in one of at least a plurality, preferably at least a plurality of pairs, i.e. at least three, of seat positions enabling the distance an operator or driver is positioned from the steering arrangement, preferably handlebars, of the motorcycle to be adjusted by changing operator or driver seat position thereby advantageously improving operator or driver ergonomics by making it more comfortable for an operator or driver to reach, grasp and use the handlebars. Where also equipped with a passenger seat, such as a pillion, disposed behind the operator or driver seat, such an ergonomic position-adjustable motorcycle seat assembly preferably is further constructed and arranged to enable passenger or rider seat position adjustment substantially in unison with operator or driver seat position adjustment such that both seats move together during seat position adjustment. A particularly preferred embodiment of such a position-adjustable motorcycle seat assembly equipped with a passenger seat, e.g., pillion, is constructed and arranged such that the position of the passenger seat can be changed independently of changing the position of the driver or operator seat thereby producing a position-adjustable motorcycle seat assembly of the present invention that not only provides improved driver or operator ergonomics and comfort but which also advantageously provides improved passenger or rider ergonomics and comfort.
In a preferred embodiment, at least one vehicle seat of the position-adjustable seat assembly is an operator or driver seat of a motorcycle that is configured to be mounted to part of the motorcycle, preferably part of its frame, in one of at least a plurality, preferably at least a plurality of pairs, i.e. at least three, of spaced apart seat positions which enable an operator or driver sitting in the seat to be positioned closer to the steering arrangement, preferably handlebars, and operator controls of the motorcycle when set in one seat position and farther away therefrom when set in another seat position. In one preferred position-adjustable motorcycle driver or operator seat, the seat includes a seat base having at least a plurality, preferably at least a plurality of pairs, i.e. at least three, fore-aft spaced apart seat position setting mounts configured such that the particular one of the mounts that engages the motorcycle in mounting the seat thereto determines or sets seat position. In one such preferred embodiment, each one of the seat position setting mounts includes a coupler configured to facilitate engagement with a portion of the motorcycle frame in mounting the seat thereto in the desired seat position associated with the particular coupler engaged therewith. In still another such preferred embodiment, each coupler can and preferably does include a receptacle defining a coupler socket configured to slidably and/or telescopically receive an outwardly projecting seat mounting tongue of a seat mounting bracket of an underlying seat-supporting portion of the motorcycle frame.
In such a preferred position-adjustable motorcycle operator or driver seat embodiment, a seat anchor preferably also is used in mounting the seat to the motorcycle after seat position adjustment. A preferred seat anchor preferably is a seat mounting bracket that includes at least a plurality, preferably at least a plurality of pairs, i.e. at least three, spaced apart fore-aft operator or driver seat position adjustment settings that enables the mounting bracket to be attached to the driver or operator seat using the seat position setting corresponding to the actual position that the seat is being mounted to the motorcycle. In a preferred embodiment, the position adjustment settings are provided by a plurality, preferably a plurality of pairs, i.e. at least three, of fore-aft spaced apart seat position defining mounting bores formed in the bracket each configured to accommodate a coupler, preferably a fastener, e.g. threaded bolt or stud, used to attach the bracket to the driver or operator seat base and help mount the seat to the motorcycle.
The seat mounting bracket preferably also includes a mounting portion extending rearwardly of the driver or operator seat that is configured not only to anchor or ground the rear of the driver or operator seat to the motorcycle but also to serve as a connector bridge between the driver or operator seat and a passenger seat, e.g. pillion, where the position-adjustable seat assembly is so equipped. In a preferred embodiment, the rearwardly extending mounting portion is a soleplate generally transversely extending between a pair of spaced apart and generally parallel fore-aft extending seat position adjuster arms defining a generally horseshoe-shaped or generally U-shaped seat anchor with each adjuster arm configured with one of a plurality, preferably plurality of pairs, i.e. at least three, driver or operator seat position settings each of which is preferably formed or defined by a corresponding seat position defining mounting bore. In such a preferred mounting bracket embodiment, the soleplate preferably also is equipped with at least a plurality, preferably a plurality of pairs, i.e. at least three, of fore-aft spaced apart passenger seat position determining mounting bores that enable the passenger seat, e.g. pillion, to be mounted thereto using one or more fasteners, e.g. threaded bolts or studs, in one of a plurality, preferably a plurality of pairs, i.e. at least three, of passenger seat positions in a manner that also enables adjustment of the passenger seat, e.g. pillion, to be done independently and/or separately of adjustment of the position of the operator or driver seat. In such a preferred embodiment, a fore-aft extending rear passenger seat mounting bracket is used to attach the rear of the passenger seat, e.g. pillion, to part of the motorcycle in at least a plurality, preferably at least a plurality of pairs, i.e. at least three, seat adjustment positions.

As depicted by
In a preferred embodiment of a position-adjustable motorcycle seat assembly 42 of the present invention, the driver seat 48 preferably is not only at least position-adjustable along a fore-aft direction but also position-adjustable along a generally vertically transverse direction relative to the motorcycle 46 to which the driver seat 48 is mounted. Where the position-adjustable motorcycle seat assembly 42 also provides driver seat adjustability in a generally vertically transverse direction, adjusting or changing the position of the driver seat 48 from one position to another position not only changes the fore-aft distance of the driver seat 48 relative to the handlebars 68 but also displaces the driver seat 48 in a generally upward or vertical direction relative thereto. Such generally upward or vertical driver seat position adjustability advantageously enables the position of the driver seat 48 to be adjusted in a generally vertical or upwards direction relative to the handlebars 68, such as depending on the anthropomorphic characteristics and/or comfort preference of the driver, advantageously enabling the driver seat 48 to be positioned in either an uppermost driver seat position (
Where equipped with a position-adjustable passenger seat 50, such as pillion 52, a preferred position-adjustable motorcycle seat assembly 42 of the present invention enables the position of the position of the driver seat 48 and passenger seat 50, e.g., pillion 52, to be adjusted substantially simultaneously together or in tandem such that adjustment of the position of the driver seat 48 also correspondingly adjusts the position of the passenger seat 50. In a preferred embodiment, the position-adjustable motorcycle seat assembly 42 can be and preferably is constructed and arranged to enable the position of the passenger seat 50, e.g., pillion 52, to be adjusted independently of the position of the driver seat 48. In one such preferred position-adjustable motorcycle seat assembly 42, position adjustment of each position-adjustable seat 48 and/or 50 preferably is independent of one another such that adjustment of the position of the passenger seat 50, e.g., pillion 52, preferably can be adjusted independently of the position of the driver seat 48 and vice versa.
As previously indicated, vehicle 44 preferably is a motorcycle 46 having an elongate longitudinally extending chassis or frame 54 carrying a plurality of fore-aft spaced apart wheels, only a rear wheel 55 of which is shown, a prime mover 56 that preferably is a motor 58, e.g., internal combustion engine 60, which drives at least one of the wheels during motorcycle operation, an energy storage unit 62 that preferably is a fuel tank 64, e.g., tear-drop shaped gasoline tank 64, for providing a source of power to prime mover 56 during motorcycle operation, a steering arrangement 66 that preferably includes handlebars 68 generically depicted in

No. 7,837,260, the entire disclosure of which is hereby expressly incorporated herein by reference, with its frame 52 having one or more portions, e.g., frame rails or tubes, extending longitudinally in a fore-aft direction, substantially the length of the motorcycle 46. Such a motorcycle frame 52 preferably includes a seat-supporting portion 72, e.g., one or more elongate frame rails or tubes, which extends longitudinally in a fore-aft direction underneath the position-adjustable motorcycle seat assembly 42 enabling each seat 48 and/or 50 of the seat assembly 42 to be carried thereby and preferably even mounted thereto. In this regard, motorcycle 46 can and preferably does have a steering arrangement 66 that includes handlebars 68 similar to or substantially the same as that shown and described in the aforementioned '260 patent that preferably include a pair of generally oppositely outwardly extending handlebar grips (not shown) which are grasped by a corresponding hand of an operator or driver (not shown) sitting in the driver seat 48 during driving operation of the motorcycle 46. Although not shown in the drawings, each one of the handlebar grips can be and preferably is equipped with one or more motorcycle controls, such as a throttle control, brake(s), gear selector control, e.g., clutch, lighting control(s), turn signal controls, and the like which can be and preferably are manipulable by a corresponding hand of a driver sitting in the driver seat 48 grasping a respective one of the handlebar grips.
The driver seat 48 of the position-adjustable motorcycle seat assembly 42 is formed of an elongate longitudinally extending saddle 74 having a generally upwardly curved concave outer seat occupant supporting surface 76 upon which rest the buttocks, tuberosity of ischium, and inner thigh portions of both legs of a rider (not shown) straddling the seat 48 when sitting in the seat 48. The seat saddle 74 has a rearwardly upwardly curved cantle 78 extending generally transversely horizontally or widthwise along a rear end 80 of the driver seat 48. The seat occupant supporting surface 76 includes a downwardly inclined seat occupant supporting surface section 82 that extends downwardly from the cantle 78 into a transitional curved central seating surface section 84 which in turn extends forwardly upwardly into an upwardly inclined surface section 86 while tapering widthwise and converging to form a generally upwardly extending pommel 88 at a front end 90 of the driver seat 48. The pommel 88 at the front end 90 of the driver seat 48 is disposed adjacent a rear end 92 of the fuel tank 64 of the motorcycle 42 and the cantle 78 at the rear end 80 of the driver seat 48 is disposed adjacent a front end 94 of the passenger seat 50. Where the position-adjustable motorcycle seat assembly 42 is also equipped with a passenger seat 50, its front end 94 preferably is disposed adjacent the rear end 80 of the driver seat 48 and extends rearwardly therefrom to a rear end 96 of the passenger seat 50 preferably defining an elongate generally oblong or oval longitudinally or fore-aft extending pillion 52.
In a preferred position-adjustable motorcycle seat assembly 42, each position-adjustable seat 48 and/or 50 of such a seat assembly 42 is substantially immovably fixed in place by being grounded to part of the motorcycle frame 54, preferably to seat-supporting portion 72, during seat position adjustment and/or when seat position adjustment is completed. As discussed in more detail below, each position-adjustable seat 48 and/or 50 of at least one preferred position-adjustable motorcycle seat assembly 42 of the present invention is configured to enable a position of each position-adjustable seat 48 and/or 50 of the seat assembly 42 to be moved from one seat position to at least one other seat position and securely retained in that position by substantially immovably fixing in place each position-adjusted seat 48 and/or 50 by grounding it to part of the frame 54.
As previously discussed, at least the driver seat 48 of the position-adjustable motorcycle seat assembly 42 is position-adjustable by being selectively movable between one preset or predetermined driver seat position, such as a first driver seat position shown in
With regard to the position-adjustable driver seat 48 of the present invention, additional reference is made to
The driver seat base 100, e.g., seat pan 98, is elongate, generally oblong, and extends longitudinally in a fore-aft direction when mounted on the motorcycle 46 thereby generally longitudinally orienting the elongate and generally oblong driver seat 48 in a fore-aft direction relative to the motorcycle 46. As discussed in more detail below, the base 100, e.g., pan 98, is configured with an adjustable seat position mounting arrangement 103 that includes a front adjustable seat position mounting arrangement 105 with at least a plurality of front seat position adjustment enabling seat mounts 106, 107 and/or 108 disposed at or adjacent a front end 110 of the base 100 and a rear adjustable seat position mounting arrangement 109 with at least one rear seat position adjustment enabling seat mount 132a, 132b, 133a, 133b, and/or 134a, 134b disposed at or adjacent a rear end 114 of the base 100 configured to enable the driver seat 48 to be position adjustable when mounted to part of the motorcycle 46.

Where it is desired to provide at least three, e.g. at least a plurality of pairs, of relative passenger seat positions, the soleplate 142 of the seat mounting bracket 136 can be further configured to form one or more additional fore-aft spaced apart passenger seat positioning pairs of bores therein that are four-aft spaced apart from one of the pairs of bores 148a, 148b and/or the other one of the pairs of bores 150a, 150b.
Although not depicted in
The passenger seat 50 preferably is attached during motorcycle assembly to the soleplate 142 of the seat mounting bracket 136 using a pair of fasteners (none), preferably bolts (not shown), which extend through a respective one of the first or forward-most passenger seat positioning pair of passenger seat mounting bores 148a, 148b to at least initially position the passenger seat 50 in the first or forward-most passenger seat position where the passenger seat 50 is disposed in a first or forward-most passenger seat position where it is closest to, e.g. abuts against, the driver seat 48. Where custom ordered or subsequently desired to adjust the position of the passenger seat 50 relative to the driver seat 48 from the first or forward-most passenger seat position, the passenger seat 50 is attached to the soleplate 142 of mounting bracket 136 by inserting the fasteners, preferably bolts, through a respective one of the second or farther rearwardly spaced passenger seat positioning pair of passenger seat mounting bores 150a, 150b to locate the passenger seat 50 relative to the driver seat 48 in a second position rearwardly spaced from the first position where the passenger seat 50 is spaced from the driver seat 48 far enough to preferably form a gap or space therebetween.
Such relative position adjustability of the passenger seat 50 relative to the driver seat 48 advantageously enables the passenger seat 50 to be moved or adjusted in position relative to the driver seat 48 from the aforementioned first or forward-most passenger seat position to a second farther rearwardly spaced passenger seat position where there is a space or gap between the driver seat 48 and passenger seat 50. In a preferred embodiment, the passenger seat 50 and mounting plate 136 are configured such that moving the passenger seat 50 from its first or forward-most position to an adjacent second more rearwardly disposed position displaces or moves the passenger seat 50 relative to the driver seat 48 by a distance of at least 5 mm and preferably by a distance of at least 10 mm. In another preferred embodiment, the passenger seat 50 and mounting plate 136 are configured such that moving the passenger seat 50 from its first or forward-most position to an adjacent second more rearwardly disposed position displaces or moves the passenger seat 50 relative to the driver seat 48 by a distance of about 10 mm thereby providing relative passenger seat adjustment therebetween that advantageously accommodates passengers having a wide range of sizes, heights and the like thereby enabling a larger passenger to be spaced farther away from the driver as a result.
To anchor the rear 96 of the pillion 52 to the motorcycle 46 in a manner that also permits seat position adjustment, an elongate generally longitudinally fore-aft extending seat-position adjustable pillion mounting bracket 176 is used that is configured to enable the position of the pillion 52 to be adjusted or moved between at least a plurality of seat positions, e.g., seat position settings, in accordance with the present invention.

An ergonomic position-adjustable vehicle seat assembly 40 constructed in accordance with the present invention capable of such driver seat displacement(s) between driver seat positions in changing driver seat position advantageously enables the position of the driver seat 48 to be adjusted or set between at least one of two positions, preferably between at least one of three or more positions, to a seat position that better accommodates a wider variety of operators or drivers thereby increasing their comfort during motorcycle use and operation. Such an ergonomic position-adjustable vehicle seat assembly 40 constructed in accordance with the present invention capable of providing such seat position displacement(s) when adjusted from one position to the next or adjacent position also advantageously enhances operator or driver comfort and motorcycle ergonomics improving operator or driver customer satisfaction. Finally, such an ergonomic position-adjustable vehicle seat assembly 40 constructed in accordance with the present invention capable of providing such seat position displacement(s) when adjusted from one position to the next or adjacent position also advantageously enables such enhanced comfort levels to be provided to a greater anthropometric range of riders including drivers or operators smaller than or falling outside of the 5th percentile and/or drivers or operators larger than or falling outside of the 95th percentile.
In addition, an ergonomic position-adjustable vehicle seat assembly 40 constructed in accordance with the present invention that also provides passenger seat or pillion adjustability also advantageously enhances passenger or rider comfort preferably in a similar manner to that of the operator or driver. Such an ergonomic position-adjustable vehicle seat assembly 40 of the present invention that is constructed and arranged as described hereinabove to allow the position of the passenger seat 50 or pillion 52 to be changed or moved relative to the driver seat 48 can and preferably does even further improve rider or passenger comfort by enabling the passenger seat 50 or pillion 52 to be displaced from a position adjacent to, adjoining or even abutting the driver seat 48 to a position spaced farther away therefrom where there is even a space of at least 5 mm, and preferably at least 10 mm, between the front 94 of the passenger seat 50 or pillion 52 and the rear 80 of the driver seat 48. Such versatile position adjustability of such constructed and arranged to provide passenger seat 50 or pillion 52 seat position adjustability independent of seat position adjustability of the driver seat 48 enables larger, heavier and/or taller passengers or riders to be better accommodated by enabling the passenger seat 50 or pillion 52 to be moved farther away from the driver seat 48 to provide the passenger or rider more space and/or legroom.
The fasteners used to adjust the position of the driver seat 48 and/or passenger seat 50, e.g., pillion 52, of such an ergonomic position-adjustable vehicle seat assembly 40 of the present invention are preferably tool less helping to produce an ergonomic fore-aft seat position adjustable seating assembly 40 that is easy for an owner or operator of the motorcycle 46 to make fore-aft seat position adjustments to one or both of the driver seat 48 and/or pillion 52. Even without use of tool less fasteners, an ergonomic fore-aft seat position adjustable seating assembly 40 constructed in accordance with the present invention advantageously enables the fore-aft position of one or both of the driver seat 48 and/or pillion 52 to be adjusted either substantially simultaneously in unison as depicted by
