1. A scissor suspension comprising:
- a first frame;
a second frame;
a scissor assembly moveably connecting the first frame with the second frame, wherein the scissor assembly comprises;
a first arm including a first end and a second end, wherein the first arm is pivotally attached to the first frame proximate to the first end;
a first bearing pivotally connected proximate to the second end of the first arm;
a second arm including a first end and a second end, wherein the second arm is pivotally connected to the first arm between the first and, second ends of the first and second arms;
a first rail attached to the second frame, wherein the first bearing is moveably coupled to the first rail;
a first damper disposed to dampen movement of the second frame relative to the first frame; and
a second damper disposed to dampen movement of the second frame relative to the first bearing.

Abstract
A scissor suspension includes a first arm having a first end and a second end. The first end may be configured for pivotal attachment to a structure and a first bearing may be pivotally connected proximate to the second end of the first arm. A second arm having a first end and a second end may be pivotally connected to the first arm between the first and second ends of the first and second arms. The first bearing may be moveably coupled to the first rail.

8. A method for using a scissor suspension, the scissor suspension comprising a first arm including a first end and a second end, wherein the first arm is pivotally attached to a structure proximate the first end, wherein the scissor suspension further comprises a first bearing pivotally connected proximate to the second end of the first arm and a second arm having a first end and a second end, the second arm being pivotally connected to the first arm between the first and second ends of the first and second arms, wherein the scissor suspension further includes a first rail and a damper disposed to dampen movement of the first rail relative to the structure, wherein the first bearing is moveably coupled to the first rail, the method comprising:
-
moving the first bearing along the first rail in response to an input motion of the structure; wiping a raceway of the-first rail as the first bearing moves along the first rail; and
dampening movement of the first rail relative to the structure. - View Dependent Claims (9, 10, 11, 12, 13)
