Stacked Disk Spring Vibration Isolator with Increased Lateral Load Capacity

A vehicle, comprising:

• a floor;
• a seat comprising;
• a backrest;
• a cushion;
• a frame;
• a slide rail configured to permit the seat to travel in a direction parallel to the floor;
• a vibration isolator comprising:
• at least two disk spring washers, wherein each disk spring washer comprises an inner edge, an outer edge, and a central opening;
• at least one ring-shaped outer spacer, wherein each outer spacer is coupled to the outer edges of one or two disk spring washers of the at least two disk spring washers;
• at least one ring-shaped inner spacer, wherein each inner spacer is coupled to the inner edges of one or two disk spring washers of the at least two disk spring washers;
• a flexible central shaft concentric with the at least two disk spring washers, the at least one outer spacer, and the at least one inner spacer;
• a bottom attachment portion coupled to a lower end of the flexible central shaft and configured to support the at least two disk spring washers;
• and
• a top attachment portion configured to slide along the flexible central shaft,
• wherein the top attachment portion is configured to, with an application of a downward force, reversibly compress the at least two disk spring washers.

A system comprising:

• a vehicle;
• a first component positioned within the vehicle;
• a second component positioned within the vehicle;
• a vibration isolator positioned between the first component and the second component, the vibration isolator comprising:
• at least two disk spring washers, wherein each disk spring washer comprises an inner edge, an outer edge, and a central opening;
• at least one ring-shaped outer spacer, wherein each outer spacer is coupled to the outer edges of one or two disk spring washers of the at least two disk spring washers;
• at least one ring-shaped inner spacer, wherein each inner spacer is coupled to the inner edges of one or two disk spring washers of the at least two disk spring washers;
• a flexible central shaft concentric with the at least two disk spring washers, the at least one outer spacer, and the at least one inner spacer;
• a bottom plate or platform coupled to a lower end of the flexible central shaft and configured to support the at least two disk spring washers;
• and
• a top plate, platform, or plunger configured to slide along the flexible central shaft,
• wherein the top plate, platform, or plunger is configured to, with an application of a downward force, reversibly compress the at least two disk spring washers.
