  • Patent number: 6336626
    Abstract: An improved stirrup suspension utilizes a multi-stage spring suspension to accommodate the different downward forces generated during normal riding as well as jumping. The stirrup suspension includes a housing having a bottom wall and continuous side wall, a slide member slidably received within the housing, a stirrup connector mounted to the lower end of said slide member, a first spring element received around the slide member, and a second spring element also received around said slide member. The first spring element is effective for exerting a force F1 under a minimum load while the second spring element is effective for exerting a force F2 that is greater than F1 under a minimum load. In use, the lower end of the slide member is attached to the stirrup which will move up and down relative to the housing. The slide member slidably moves within housing where a flange member at the top of the slide compresses the first and second spring elements upon the exertion of a downward force on the stirrup.
