Abstract: A locationally adjustable pedal is provided for providing a force input to an automotive vehicle control.

Abstract: A seal and scraper assembly for a ball screw and nut actuator has a resilient seal ring for reception by the nut which includes a radially internal helical thread mating with the screw groove. The seal ring further has a radially compressible annular lip extending at an angle in an axially outboard direction from the outer periphery of the ring to engage and be radially compressed by the nut. A rigid, annular mount ring also has an internal thread received by the screw groove which has an axially inboard portion interfitting with the seal ring so as to permit relative axial movement of the seal ring and mount ring, while preventing relative rotation of the rings.

Abstract: A seal and scraper assembly for a nut and screw actuator has an elastomeric member bonded to a metal ring. The elastomeric member has an annular lip outer portion and a helical thread form inner portion. The inner portion has a plurality of scraper or wiper surfaces interrupting the thread form at an oblique angle and cooperating with a lubricant return surface to direct lubricant, scraped from the screw thread surface, into the housing enclosing the nut and screw actuator. A web portion extends between the outer lip and the inner thread form along the same angle as each scraper surface so that a component of the assembly forces on the outer lip portion are transmitted to the scraper surface so as to increase the thread sealing and scraping forces.
