ABSTRACT:
A motorcycle seat having a backrest that is angularly adjustable, height adjustable and removable, all without requiring any tool. The backrest is mounted by a bracket to a pivot bracket carried by a frame of a backrest adjustment assembly all of which are disposed below the surface of the seat cushion. The assembly has a prime mover coupled to the frame and pivot bracket and communicates by cable with an actuator allowing selective angular backrest adjustment. The prime mover preferably is a gas cylinder, such as a rigid-in-compression gas spring, or a ball screw. The mounting bracket is pivotally coupled to the pivot bracket and has a coil spring between brackets which urges the mounting bracket rearwardly against the pivot bracket permitting the backrest to be manually urged forwardly to permit entry or exit from the seat and returning to its adjusted position when released. The mounting bracket has a pocket into which a post of the backrest is received and a retaining leaf which engages the post to retain it. The leaf can be urged away from the pocket to remove the post and backrest. A backrest cushion is mounted by a slide to the post and uses a reciprocable spring biased shaft which rides in a detent slot in the post enabling the height of the cushion to be adjusted.
