Abstract
A motorcycle backrest adjusting system includes a motorcycle that has a seat and a pair of support bars that extend rearward from the seat. A pair of lower brackets is provided and each of the lower brackets is attached to one of the support bars. A pair of upper brackets is provided and each of the upper brackets is moveably coupled to one of the lower brackets. Each of a pair of guide tracks is attached to and extends along one of the upper brackets. A drive apparatus selectively moves the upper brackets with respect to the lower brackets. A control is operationally coupled to the drive apparatus. A backrest is mounted to the upper brackets and faces toward a pair of handlebars of the motorcycle. The backrest is selectively moved toward or away from the seat.
Claims5
An automatic motorcycle backrest adjustment assembly, said assembly comprising:
- a motorcycle having a seat, a pair of support bars being attached to said motorcycle and extending rearward from said seat, said support bars being orientated parallel to each other and being substantially horizontally orientated;
- a pair of lower brackets, each of said lower brackets being attached to one of said support bars, each of said lower brackets including a first vertical panel and second vertical panel each having an upper edge and an upper panel attached to and extending along each of said upper edges, a slot being defined between respective ones of said first and second vertical panels, each of said support bars being positioned in one of said slots, each of a plurality of fasteners extending through one of said support bars and adjacent ones of said first and second vertical panels;
- a pair of upper brackets, each of said upper brackets being moveably coupled to one of said lower brackets;
- a pair of guide tracks, each of said guide tracks being attached to and extending along a length of one of said upper brackets;
- a drive apparatus being fixedly attached to said lower brackets, said drive apparatus being mechanically coupled to said guide tracks, said drive apparatus selectively moving said upper brackets with respect to said lower brackets;
- a control being operationally coupled to said drive apparatus to selectively turn said drive apparatus in a first direction or in a second direction;
- a backrest being mounted to said upper brackets at a fixed angle and facing toward a pair of handlebars of the motorcycle;
- and
- wherein said upper brackets and said backrest may be selectively moved toward or away from said seat.
