Mechanism for adjusting backrest of a motorcycle

The present invention is a mechanism for adjusting backrest of a seat of a motorcycle that moves backrest towards and away from seat thereby adjusting sitting space as desired for different users. The mechanism includes a connecting bracket and a sliding bracket. Connecting bracket connects backrest and central bracket which is a part of the motorcycle that conventionally connects backrest to fender bracket disposed on a fender. Sliding bracket is connected at a bottom portion of central bracket and slides on fender bracket. When sliding bracket slides, central bracket and connecting bracket slides, thereby sliding backrest towards and away from seat of motorcycle. Thus, as desired space between backrest and seat can be increased or reduced to provide comfortable sitting on seat.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present disclosure relates to a backrest of a motorcycle. More particularly, the present disclosure relates to a mechanism for adjusting backrest of a motorcycle such that backrest moves towards and away from a seat.

2. Description of the Related Art

Owing to confined space of pillion seats sandwiched between a pillion backrest and a rider backrest, pillion riders feel uncomfortable to travel a long journey. Hence, there is a need for a mechanism that adjusts a backrest of a motorcycle so that a rider can adjust by increasing and decreasing space between a seat and backrest and enjoy a comfortable ride.

Several designs for backrest adjustment for motorcycles have been designed in the past. None of them, however, includes a mechanism for adjusting backrest that slides backrest towards and away from a seat of a motorcycle and is structurally compact and featured to provide more space between a backrest and a seat of a motorcycle.

Applicant believes that a related reference corresponds to a U.S. Pat. No. 6,761,401 filed by Leo McGlynn for Telescoping motorcycle seat backrest. The Leo reference discloses a motorcycle seat backrest that telescopes up and down, to remain out of the way when not needed and to be adjustable as to height when needed. However, the backrest is not adjustable for increasing sitting space between the backrest and seat.

Another related application is U.S. Pat. No. 6,224,081 by Harley-Davidson Motor Co Group Inc. for an adjustable backrest for a motorcycle. The patent '081 discloses a backrest that is provided with a torsion adjustment. However, the adjustable backrest disclosed in the reference '081 is silent on increasing space between the backrest and seat.

SUMMARY OF THE INVENTION

It is an object of the present invention to provide a mechanism for adjusting backrest of a seat of a motorcycle that moves backrest towards and away from seat thereby adjusting sitting space as desired.

It is yet another object of the present invention to provide a structurally compact mechanism for adjusting backrest of a seat of a motorcycle for providing sufficient space between backrest and space.

It is still another object of the present subject matter to provide a mechanism for adjusting backrest of a seat of a motorcycle that is easily retrofitted in an existing motorcycle or can be fitted in a new motorcycle.

DETAILED DESCRIPTION OF THE EMBODIMENTS OF THE INVENTION

Referring now to the drawings,FIGS. 1-7, where the present invention is generally referred to with numeral10, it can be observed that a mechanism for adjusting a backrest20of a seat30of a motorcycle40defined with a fender bracket50disposed on a fender60and a central bracket70, in accordance with one embodiment, is provided that includes a connecting bracket80and a sliding bracket90.

Connecting bracket80connects backrest20and central bracket70which is generally a part of a motorcycle. Generally, central bracket70, herein the present disclosure refers to a bracket that conventionally connects backrest20to fender bracket50in existing motorcycles. In one embodiment, connecting bracket80is substantially square in shape, as clearly illustrated inFIGS. 4 and 5. Square shaped connecting bracket80having four sides81,82,83, and84of which adjacently disposed sides83and84is provided with a gap85therebetween and side84is taper. Square shape of connecting bracket80creates an additional structural space between backrest20and central bracket70.

Sliding bracket90is connected at a bottom portion of central bracket70. Sliding bracket90has an upper portion and a lower portion. Upper portion is connected to central bracket70. Lower portion of sliding bracket90selectively slides on fender bracket50such that sliding bracket90slides central bracket70and connecting bracket80and thereby slides backrest20towards and away from seat30.

Thus, by adding connecting bracket80and sliding bracket90, backrest50can move approximately around 4 inches such that a sufficient space is formed between backrest20and seat30. Though, as mentioned one can increase space between backrest20and seat30around 4 inches, however, space can be increased above 4 inches or decreased below 4 inches as per various models of motorcycles.
