Abstract

A counterbalance includes a first attachment strap, and an arbor rotatably supported by the first attachment strap. A second attachment strap is attached to the arbor, and is rotatable with the arbor about a winding axis. A spiral spring interconnects the first attachment strap and the second attachment strap. A spring support is attached to the second attachment strap. The spring support includes an annular wall that is disposed circumferentially about and concentric with the winding axis. The annular wall is radially positioned relative to the winding axis to contact an outermost coil of spiral spring, to position the spiral spring in a spiral orientation about the winding axis, such that each coil of the spiral spring moves away from the winding axis with a substantially constant angular velocity to provide a substantially equal radial spacing between adjacent coils of the spiral spring.

Description

technical field [0001] The present invention relates generally to a balancing mechanism, and more particularly to a balancing mechanism having a helical spring positioned concentrically about a winding axis. Background technique [0002] Balancing mechanisms are often used to bias a first component relative to a second component. For example, a vehicle may include a counterbalance mechanism for biasing the hood or decklid relative to the vehicle structure. The balance mechanism provides a biasing force that assists or assists in moving the first component relative to the second component. The biasing force from the balance mechanism reduces the force the user must apply to lift or move the first part relative to the second part. [0003] The balance mechanism typically includes a spring that is used to provide the biasing force of the balance mechanism. One type of spring used in balancing mechanisms is a coil spring. The helical spring may alternatively be referred to a...
