Seat Adjuster

Uses a tolerance ring between the handle drive gear and seat position gear that acts a simple overload protection – protecting the seat adjuster from operator abuse.


Benefits include:

Tolerance Rings are radial spring fasteners
that are press fitted between two mating components. This generates a retention force that fixes those components together, whilst also satisfying other functional requirements such as Torque Drive, Overload Protection, NVH Performance and Differential Thermal Expansion.


Fasten annular components
Reduce noise & vibration
Compensating for thermal expansion
Predictable & repeatable slip
Avoid resonance frequencies
